冰箱及其控制方法 Refrigerator and control method

本发明涉及一种冰箱,具体地说,涉及一种冰箱及控制它的方法,它能够实施对冰箱故障状态的自我检查并自动地将与故障有关的信息通过因特网发送给服务中心。 The present invention relates to a refrigerator, and more particularly, it relates to a refrigerator and a control method, it is possible to implement a fault condition of the refrigerator self-examination and automatically transmits information about the failure to the service center via the Internet.

一般说来,冰箱具有一个制冷循环,即吸收冷藏室和冷冻室内的热量并将所吸收的热量发射出冷藏室和冷冻室之外,以便使冷藏室和冷冻室内部的温度保持在比室温更低的温度。 In general, a refrigerator having a refrigeration cycle, i.e., absorb heat the refrigerating compartment and the freezing compartment and the absorbed heat emitted outside the refrigerator compartment and the freezer compartment, refrigerator compartment and the freezer compartment so that the internal temperature is maintained at room temperature for more than low temperatures. 蒸发器(冷却器)(未示出)在低于冷藏室和冷冻室内部温度的温度下吸收冷藏室和冷冻室内部的热量。 An evaporator (cooler) (not shown) absorption refrigerator and freezer at a temperature below the heat inside the refrigerator compartment and the freezer compartment inside temperature.

一般说来,为了保持冷冻室内部的温度不高于-18℃,蒸发器的温度应该不高于-23℃。 In general, in order to maintain the temperature inside the freezer compartment is not higher than -18 ℃, the evaporation temperature should be no higher than -23 ℃.

因此,蒸发器的温度在冷藏室和冷冻室内部是最低的,当冷藏室和冷冻室内部有一定数量的潮气(霜)时,在冷藏室和冷冻室内部的潮气就聚集在具有最低温度的蒸发器上,蒸发器的效率会下降,因此,就要周期性地去除潮气(霜)。 Accordingly, the evaporation temperature inside the refrigerator compartment and the freezer compartment is the lowest, when the refrigerator compartment and the freezer compartment has a number of internal moisture (cream), moisture in the inside of the refrigerator compartment and the freezer compartment having gathered at the lowest temperature evaporator, evaporator efficiency drops, therefore, it is necessary to periodically remove the moisture (cream).

图1是说明按照已有技术的普通冰箱的透视图。 Figure 1 is a prior art in accordance with the ordinary refrigerator perspective.

如图1所示,冰箱包括一个冷冻室3,一个冷藏室4,用于储存(保鲜)食品,以及门2、5,用于有选择地开启和关闭冷冻室3和冷藏室4。 1, the refrigerator includes a freezing chamber 3, a refrigerating compartment 4, for storing (fresh) food, and a gate 2,5, for selectively opening and closing the freezing compartment 3 and refrigerating compartment 4. 更详细地说,冰箱1能够在一定程度上保持冷冻室3和冷藏室4内部的温度而保持储存在冷冻室3和冷藏室4中的食物的新鲜度。 In more detail, a refrigerator capable of maintaining the freezing compartment 3 and the temperature inside the refrigerating compartment 4 to some extent while maintaining the freshness stored in the freezing compartment 3 and refrigerating compartment 4 of food.

为了维持储存在冷冻室3和冷藏室4中的食物的新鲜度,冰箱1有一个由下列部件构成的制冷循环,即压缩制冷剂的压缩机(未示出)、产生冷却空气以吸收储存在冰箱中的食物的热量的蒸发器(未示出)、对在蒸发器中受到高压的制冷剂解除压力的膨涨阀(未示出)、以及将从膨涨阀来的制冷剂凝结成为液体(water)的凝结器(未示出)。 In order to maintain freshness stored in the freezing compartment 3 and refrigerating compartment 4 in food, the refrigerator 1 has a refrigeration cycle by the following parts, i.e., for compressing a refrigerant compressor (not shown), to generate cooling air in the absorbent storage an evaporator (not shown), by pressure of the refrigerant in the evaporator pressure releasing swell valve (not shown), and a valve to swell from the refrigerant refrigerator heat food condensed into liquid (water) in the condenser (not shown). 当制冷剂循环用于冰箱1中时,冷冻室3和冷藏室4内部的温度便由冷却空气所设定,这冷却空气是由蒸发器产生的并在冷冻室3和冷藏室4中循环。 When a refrigerant cycle for a refrigerator, a freezing chamber 3 and the temperature inside the refrigerating compartment 4 will be set by cooling air, the cooling air which is generated by the evaporator and circulated in the freezing compartment 3 and refrigerating compartment 4.

但是,当冰箱1出毛病时,用户通常并不确切地知道故障的原因,并且会通过电话、传真等向维护人员请求维修。 However, when the refrigerator one go wrong, users often do not know exactly what the cause, and will request repairs to maintenance personnel by phone, fax, etc. 然而,直接向维护人员打电话对某些用户而言可能会有麻烦。 However, a direct call to the maintenance staff for some users may have trouble. 更详细地说,当用户召唤维护人员时,维护人员可能通过电话向用户提出若干问题而判断故障的原因,但是并不是所有的用户能够回答出维护人员所提问题的正确答案。 More specifically, when a user call maintenance personnel, maintenance personnel may raise a number of questions to the user via phone and determine the cause of failure, but not all users will be able to answer the question of maintenance personnel the correct answer. 例如,并不熟悉家用电器的用户就不能够回答出维护人员的各种问题。 For example, users are not familiar with appliances maintenance personnel will not be able to answer a variety of questions.

在召唤维护人员之后,尽管维护人员来访并正确地判断出故障的原因,但在没有所需部件或设备时,维护人员仍不能修复故障而只能再度来访。 After the call maintenance personnel, although the maintenance staff and visitors to properly determine the cause of the failure, but in the absence of the necessary parts or equipment, maintenance personnel still can not fix the fault and can only re-visit.

与此同时,当用户并不认识到冰箱出故障时,用户可能因冰箱的故障而受到伤害。 At the same time, when the user does not know when the refrigerator fails to users may be due to failure of the refrigerator and hurt. 例如,当温度设定功能并不正常工作时,储存在冷冻室3和冷藏室4中的食物将丧失其新鲜度,而在最坏情况下将会坏掉。 For example, when the temperature setting function is not working properly, stored in the freezing compartment 3 and the refrigerating chamber 4 in the food will lose its freshness, and in the worst case will be broken.

此后,冰箱1的构造和操作将参照附图2而作说明。 Thereafter, the construction and operation of the refrigerator 1 will be described with reference to the accompanying drawings and 2.

图2是说明按照已有技术的冰箱操作控制装置的构造的方块图。 Figure 2 is a refrigerator constructed according to the prior art operation control device of a block diagram.

如图2所示,该操作控制装置包括一提供交流电源的电源单元24,一通过使用传感器并输出传感信号而检测冷冻室3和冷藏室4内部温度的温度传感单元26,一根据从用户来的请求信号输出一个指令信号的输入单元22,一由电源单元24提供的交流电源而运行的微型计算机25,它按照从温度传感单元26来的传感信号输出各种控制信号,并根据从输入单元22输出的指令而执行有关操作,一按照微型计算机25的控制信号显示冷冻室3和冷藏室4的当前状态(温度)的显示单元21,以及一按照微型计算机25的控制信号操作压缩机的马达(未示出)的负载单元23。 2, the operation control means includes a power supply providing AC power supply unit 24, by using a sensor and a sensor output signal and detecting the freezing compartment 3 and refrigerating compartment 4 the internal temperature of the sensing unit 26, according to a from 22, a microcomputer 24 by the power supply unit to provide AC power and run 25, which outputs various control signals in accordance with the temperature sensing unit 26 for sensing a signal from a user input unit outputs a request signal to the command signal, and And run the operation according to the output from the command input unit 22, a microcomputer 25 according to the control signal display 21, and a control signal in accordance with the operation of the microcomputer 25 of the current state of the freezer compartment 3 and 4 of the refrigerator compartment (temperature) of the display unit compressor motor (not shown) load cell 23.

首先,电源单元24向微型计算机25提供交流电源。 First, the power supply unit 24 to provide AC power to the microcomputer 25.

微型计算机25在电源单元24向它提供交流电源后就控制冰箱1的各个组成部分,更详细地说,微型计算机25被输入从温度传感单元26输出的传感信号并控制负载单元23。 The microcomputer 25 in the power supply unit 24 which provides AC power to the various components of the control after the refrigerator 1, and more particularly, the microcomputer 25 is input to the sensor signal from the temperature sensing unit 26 and controls the output of load cell 23. 在这里,负载单元23按照从微型计算机25来的控制信号操作冰箱1。 Here, the load cell 23 according to the operation control signal 25 to the microcomputer 1 from the refrigerator. 此外,微型计算机25被输入从温度传感单元26来的传感信号并控制显示单元21。 In addition, the microcomputer 25 is input from the temperature sensing unit 26 to the sensor signal and controls the display unit 21. 在这里,显示单元21按照从微型计算机25来的控制信号显示当前状态(温度),以便通知用户冰箱的当前状态(温度)。 Here, the display unit 25 to the microcomputer 21 in accordance with a control signal from the display of the current status (temperature), to notify the user of the current status of the refrigerator (temperature).

与此同时,微型计算机25对通过温度传感单元26检测的冷冻室3和冷藏室4内的温度是否高于最初设定的温度进行判断。 At the same time, the temperature inside the 4 microcomputer 25 through the temperature sensing unit 26 detects the freezing compartment 3 and the refrigerating compartment is higher than the initially established temperature is determined.

在判断过程中,当冷冻室3和冷藏室4内的温度低于初始设定的温度时,微型计算机25就控制负载单元23使其将压缩机的马达关掉。 In the determination process, when the temperature inside the freezer compartment 4 and a refrigerator compartment 3 is lower than the initial set temperature, the microcomputer 25 controls the load on the compressor unit 23 so that it will turn off the motor.

相反,在判断过程中,当冷冻室3和冷藏室4内的温度高于最初的设定温度时,微型计算机25就控制负载单元23使其将压缩机的马达通电。 On the contrary, in the determination process, when the temperature inside the freezer compartment 4 and a refrigerator compartment 3 is higher than the initial set temperature, the microcomputer 25 controls the load on the motor unit 23 is energized so that the compressor. 更详细地说,微型计算机25通过重复地控制负载单元23来调节冷冻室3和冷藏室4内部的温度,即当冷冻室3和冷藏室4内的温度高于初始设定的温度时就使压缩机的马达通电,而当冷冻室3和冷藏室4内的温度低于初始设定的温度时就控制负载单元23去关掉压缩机的马达。 More specifically, the microcomputer 25 repeatedly by the control unit 23 to adjust the load freezing compartment 3 and the temperature inside the refrigerator compartment 4, i.e., when the temperature inside the freezer compartment 4 and the refrigerating chamber 3 higher than the initial set temperature when it makes the compressor motor is energized, and when the temperature inside the freezer compartment 4 and a refrigerator compartment 3 is lower than the initial set temperature to control the loading unit 23 to turn off the compressor motor.

但是,当冰箱出毛病时,用户就要在检查功能有故障的部件或部件中的缺陷后通过电话或书面形式请求修理。 However, when the refrigerator out of order, the user must check the function after a failure in part or component defect repair requests by phone or in writing. 此后,维护人员来访并检验故障,但是由于需要时间来检查功能故障并准备所需部件,因而不能提供快速维护。 Since then, the maintenance staff to visit and examine the fault, but because it takes time to check and prepare the required components malfunctions, and therefore can not provide quick maintenance.

如上所述,在按照现有技术的冰箱1中,当冰箱出毛病时,不太懂得家用电器的用户不能正确地回答维护人员的问题。 As mentioned above, in accordance with the prior art refrigerator when the refrigerator go wrong, do not know the user appliances can not correctly answer questions maintenance personnel.

此外,当冰箱1出毛病时,尽管维护人员来访并正确地判断了故障的原因,但当没有所需的部件或设备时,维护人员就得再次上门,因此不能提供快捷和正确的维护。 In addition, when the refrigerator one go wrong, although maintenance personnel visiting and correctly determine the cause of the failure, but without the required parts or equipment, the maintenance personnel have the door again, and therefore can not provide fast and proper maintenance.

另外,当用户没有认识到冰箱有故障时,储存在冷冻室3和冷藏室4中的食物将丧失新鲜度而在最坏的情况下将会坏掉。 Further, when the user does not recognize that there is a fault to the refrigerator, the freezing chamber 3 and stored in the refrigerating compartment 4 will lose freshness of food and in the worst case will be broken.

因此,本发明的目的是提供一种冰箱及控制它的方法,它能够通过立即检测到冰箱中的故障并自动地通过电子邮件将有关故障的信息发送到维修中心或者送给维护人员,从而快速地维修冰箱的故障。 Accordingly, an object of the invention is to provide a refrigerator and control method for it, and it can be automatically sent by the refrigerator immediately detected fault information via e-mail about the failure to the maintenance center or to the maintenance personnel to quickly Failure to repair the refrigerator.
