Description

독립냉각방식 냉장고Independent Cooling Refrigerator

본 발명은 냉매를 압축하는 압축기와, 상기 압축기로부터의 냉매를 증발시켜 냉동실 및 냉장실에 공급하는 냉기를 각각 생성하는 냉동실증발기 및 냉장실증발기<와, 상기 각 증발기에서 생성된 냉기를 냉동실과 냉장실로 각각 송풍하는 냉동실팬 및 냉장실팬을 갖는 독립냉각방식 냉장고에 관한 것이다.The present invention provides a compressor for compressing a refrigerant, a freezer compartment evaporator and a refrigerator compartment evaporator for generating cool air for evaporating the refrigerant from the compressor and supplying it to the freezer compartment and the refrigerating compartment, respectively, and the cold air generated by each evaporator to the freezer compartment and the refrigerator compartment, respectively. An independent cooling method refrigerator having a freezing chamber fan and a refrigerating chamber fan to be blown.

냉장고는 냉동실 및 냉장실에 냉기를 공급하기 위한 냉각시스템을 가지고 있다. 냉각시스템은 압축기, 응축기 및 증발기 등으로 구성되며, 압축기는 외부전원으로부터 전원을 공급받아 냉매를 압축하고, 압축기에서 압축된 냉매는 응축기에서는 응축되며, 증발기에서는 응축기에서 응축된 냉매를 증발시켜 냉기를 생성한다. 증발기에서 생성된 냉기는 송풍팬에 의해 냉장실 및 냉동실로 송풍된다.The refrigerator has a cooling system for supplying cold air to the freezer compartment and the refrigerating compartment. The cooling system consists of a compressor, a condenser and an evaporator, and the compressor receives power from an external power source to compress the refrigerant, and the refrigerant compressed in the compressor is condensed in the condenser, and the evaporator evaporates the refrigerant condensed in the condenser. Create The cold air generated in the evaporator is blown into the refrigerating chamber and the freezing chamber by the blowing fan.

독립냉각방식 냉장고에서는 냉동실 및 냉장실에 각각 대응하여 상호 직렬로 연결된 한 쌍의 증발기가 마련되어 있으며, 각 증발기에서 생성된 냉기는 그에 부속된 송풍팬에 의하여 냉동실 및 냉장실에 공급된다. 냉동실과 냉장실은 그 설정온도가 각각 다르고, 그에 따라 각 증발기에 부속된 송풍팬의 동작 시간이 다르므로 냉동실 냉각시스템과 냉장실 냉각시스템은 각각 다르게 제어되어야 한다.In the independent refrigerator type refrigerator, a pair of evaporators connected to each other in series are respectively provided corresponding to the freezer compartment and the refrigerating compartment, and the cold air generated in each evaporator is supplied to the freezer compartment and the refrigerating compartment by a blower fan attached thereto. The freezer compartment and the refrigerating compartment have different set temperatures, and thus the operating time of the blower fan attached to each evaporator is different, so the freezer compartment cooling system and the refrigerating compartment cooling system must be controlled differently.

이러한 냉각시스템의 온도를 제어하기 위하여, 종래의 냉장고에는 냉동실 및 냉장실의 온도를 측정하는 온도센서와 마이컴 등으로 구성된 제어장치가 설치되어 있다. 마이컴은 냉동실 및 냉장실의 온도센서로부터 측정된 온도에 기초하여 압축기 및 각 송풍팬의 작동을 제어한다.In order to control the temperature of such a cooling system, a conventional refrigerator is provided with a control device composed of a temperature sensor and a microcomputer for measuring the temperature of the freezer compartment and the refrigerating compartment. The microcomputer controls the operation of the compressor and each blower fan based on the temperature measured from the temperature sensors of the freezer compartment and the refrigerator compartment.

그런데, 이러한 종래의 독립냉각방식 냉장고에서는 냉동실 및 냉장실의 온도제어를 위해 비교적 고가의 온도센서 및 마이컴과 비교적 복잡한 제어프로그램을 필요로 한다. 그래서, 이러한 전자제어방식은 전체적 제조비용이 증대하며, 부품의 수가 많으므로 작동불량이 발생할 가능성이 높다.However, such a conventional independent cooling type refrigerator requires a relatively expensive temperature sensor and a microcomputer and a relatively complicated control program for temperature control of the freezer compartment and the refrigerator compartment. Therefore, this electronic control method increases the overall manufacturing cost, and there is a high possibility of malfunction due to the large number of parts.

따라서, 본 발명의 목적은, 비교적 간단하고 저렴한 구조로 냉동실 및 냉장실의 온도제어가 가능하고 작동불량이 적은 독립냉각방식 냉장고를 제공하는 것이다.Accordingly, it is an object of the present invention to provide an independent cooling type refrigerator having a relatively simple and inexpensive structure, capable of controlling the temperature of the freezer compartment and the refrigerating compartment and having a low malfunction.

An independent cooling method refrigerator having a freezing compartment fan and a refrigerating compartment fan, each of which is blown into a freezing compartment and a refrigerating compartment, comprising: a freezing chamber thermostat for controlling power to the freezing compartment fan and the compressor according to a predetermined set temperature in the freezing compartment, and a predetermined inside the refrigerating compartment. Independent cooling method characterized in that it comprises a refrigerator compartment thermostat for controlling the power supply of the refrigerator compartment fan according to the set temperature of the refrigerator compartment thermostat, the freezer compartment fan and the compressor are connected in parallel to the freezer compartment thermostat. Achieved by the refrigerator.

이하, 도면을 참조하여 본 발명을 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the drawings.

도 1은 본 발명에 따른 독립냉각방식 냉장고의 단면도이고, 도 2는 독립냉각방식 냉장고의 냉각시스템 구성도이다. 이들 도면에 도시된 바와 같이, 독립냉각방식 냉장고는 냉동실(11)과 냉장실(15)이 형성되어 있는 본체(10)와, 냉동실(11) 및 냉장실(15)의 전면에 각각 형성되어 있는 개구를 회동개폐하는 냉동실도어(12) 및 냉장실도어(16)를 가진다. 냉장고 본체(10)의 후방 하부에는 냉매를 압축하는 <단일의 압축기(2)와 이 압축기(2)에서 압축된 고온 고압의 가스를 응축시키는 응축기(3)가 마련되어 있으며, 응축기(3)에서 응축된 냉매를 증발시켜 냉기를 생성하는 냉동실증발기(4) 및 냉장실증발기(5)가 응축기(3)에 직렬로 순차 연결되어 있다. 또한, 냉동실증발기(4) 및 냉장실증발기(5)에서 생성된 냉기는 냉동실송풍팬(6)과 냉장실송풍팬(7)에 의해 냉동실(11) 및 냉장실(15)에 각각 공급된다.1 is a cross-sectional view of an independent cooling refrigerator according to the present invention, Figure 2 is a block diagram of a cooling system of the independent cooling refrigerator. As shown in these figures, the independent cooling refrigerator includes an opening formed in the main body 10 in which the freezing compartment 11 and the refrigerating compartment 15 are formed, and the front surfaces of the freezing compartment 11 and the refrigerating compartment 15, respectively. It has a freezing compartment door 12 and the refrigerating compartment door 16 which rotate and open. A single compressor 2 for compressing the refrigerant and a condenser 3 for condensing the gas of a high temperature and high pressure compressed by the compressor 2 are provided at the rear lower part of the refrigerator main body 10, and the condenser 3 is condensed. The freezer compartment evaporator 4 and the refrigerator compartment evaporator 5 which evaporate the refrigerant to generate cold air are sequentially connected to the condenser 3 in series. In addition, the cold air generated by the freezer compartment evaporator 4 and the refrigerator compartment evaporator 5 is supplied to the freezer compartment 11 and the refrigerating compartment 15 by the freezer compartment blower 6 and the refrigerator compartment blower 7, respectively.

이에 의해, 압축기(2)가 구동하면, 냉매는 응축기(3)를 거쳐 냉동실증발기(4) 및 냉장실증발기(5)에서 증발하여 주위 공기를 냉각시킴으로써 냉기를 생성하고, 각 증발기(4,5)에서 생성된 냉기는 냉동실송풍팬(6) 및 냉장실송풍팬(7)에 의하여 냉동실(11) 및 냉장실(15)로 각각 공급된다.Thereby, when the compressor 2 is driven, the refrigerant evaporates in the freezer compartment evaporator 4 and the refrigerating chamber evaporator 5 via the condenser 3 to cool the ambient air, thereby producing cold air, and the respective evaporators 4 and 5. The cold air generated in the is supplied to the freezing compartment 11 and the refrigerating compartment 15 by the freezing compartment blowing fan 6 and the refrigerating compartment blowing fan 7, respectively.

도 3은 본 발명에 따른 독립냉각방식 냉장고의 온도제어를 위한 제어회로도이다. 이 도면에 도시된 바와 같이, 압축기(2), 냉동실팬모터(6′) 및 냉장실팬모터(7′)는 전원공급부(1)에 대해 병렬로 연결되어 있다. 또한, 전원공급부(1)로부터의 전원공급은 냉동실서모스탯(8)을 통해 압축기(2), 냉동실팬모터(6′) 및 냉장실팬모터(7′)에 공급된다. 냉동실서모스탯(8)은 냉동실(11)내에 설치되어 소정의 설정온도에 따라 각 요소들(2,6′,7′)로 향한 전원을 단속한다. 또한, 냉장실팬모터(7′)로의 분기전원라인내에는 냉장실서모스탯(9)이 설치되어, 냉장실(15)내의 온도에 따라 냉장실팬모터(7′)로의 전원공급을 단속한다.3 is a control circuit diagram for temperature control of the independent cooling type refrigerator according to the present invention. As shown in this figure, the compressor 2, the freezer compartment fan motor 6 'and the refrigerating compartment fan motor 7' are connected in parallel to the power supply unit 1. In addition, the power supply from the power supply unit 1 is supplied to the compressor 2, the freezer compartment fan motor 6 'and the refrigerating compartment fan motor 7' through the freezer compartment thermostat 8. The freezer compartment thermostat 8 is installed in the freezer compartment 11 to intercept power to each of the elements 2, 6 ′, 7 ′ according to a predetermined set temperature. In addition, a refrigerating chamber thermostat 9 is provided in the branch power supply line to the refrigerating chamber fan motor 7 'and intermittently supplies power to the refrigerating chamber fan motor 7' according to the temperature in the refrigerating chamber 15.

이러한 구성에 의하여, 냉동실(11)내의 온도가 소정의 설정온도 이상 올라가면 냉동실서모스탯(8)은 ON으로 되고, 전원은 압축기(2)와 냉동실팬모터(6′) 및 냉장실팬모터(7′)로 공급되어 냉매의 순환에 의해 냉동싸이클이 반복된다. 이 <때, 냉동실증발기(4)와 냉장실증발기(5)에서는 냉기가 계속 생성되며, 생성된 냉기는 냉동실송풍팬(6)에 의하여 냉동실(11)로 공급된다. 또한, 냉동실(11)의 온도가 설정온도 이하로 내려가면 냉동실서모스탯(8)은 OFF 상태로 되어 압축기(2)와 냉동실팬모터(6′) 및 냉장실팬모터(7′)로의 전원공급이 중단된다. 그러므로, 냉매의 순환에 의한 전체적인 냉동싸이클의 동작은 정지하며, 냉동실송풍팬(6) 및 냉장실송풍팬(7)도 동작을 멈추게 된다.By this configuration, when the temperature in the freezer compartment 11 rises above a predetermined set temperature, the freezer compartment thermostat 8 is turned on, and the power is supplied to the compressor 2, the freezer compartment fan motor 6 'and the refrigerating compartment fan motor 7'. The refrigeration cycle is repeated by circulation of the refrigerant. At this time, in the freezer compartment evaporator 4 and the refrigerator compartment evaporator 5, cold air continues to be generated, and the generated cold air is supplied to the freezer compartment 11 by the freezer compartment blower fan 6. In addition, when the temperature of the freezer compartment 11 falls below the set temperature, the freezer compartment thermostat 8 is turned off, and the power supply to the compressor 2, the freezer compartment fan motor 6 ', and the refrigerating compartment fan motor 7' is stopped. It stops. Therefore, the operation of the entire refrigeration cycle by the circulation of the refrigerant is stopped, and the freezing compartment blowing fan 6 and the refrigerating compartment blowing fan 7 also stop the operation.

한편, 냉동실서모스탯(8)이 ON 상태로 지속되는 동안, 냉장실(15)의 온도가 소정의 설정온도 이상으로 되어 냉장실서모스탯(9)이 ON 상태로 되면 냉장실팬모터(7′)는 구동되며 냉장실송풍팬(7)을 동작시킨다. 이에 따라, 냉장실증발기(5)에 의해 생성된 냉기가 냉장실(15)로 공급된다. 또한, 냉동실서모스탯(8)이 ON 상태인 동안 냉장실(15)내의 온도가 설정온도 이하이면 냉장실서모스탯(9)은 OFF 상태로 되며 이 때에는 냉장실팬모터(7′)가 구동하지 않으므로 냉장실(15)에는 냉기가 공급되지 않는다.On the other hand, the refrigerator compartment fan motor 7 'is driven when the temperature of the refrigerator compartment 15 becomes higher than a predetermined set temperature while the refrigerator compartment thermostat 9 is turned ON while the freezer compartment thermostat 8 is kept ON. And operates the refrigerating chamber blowing fan 7. As a result, cold air generated by the refrigerator compartment evaporator 5 is supplied to the refrigerator compartment 15. In addition, if the temperature in the refrigerating chamber 15 is lower than the set temperature while the freezer thermostat 8 is ON, the refrigerating chamber thermostat 9 is turned OFF. 15) No cold air is supplied.

이와 같이, 냉장실송풍팬(7)은 냉동실서모스탯(8)이 ON인 기간 중 냉장실서모스탯(9)이 ON인 시간에만 동작하고, 냉동실서모스탯(8)이 OFF 상태이면 냉장실송풍팬(7)도 동작하지 않는다.As described above, the refrigerating air blowing fan 7 operates only at the time when the refrigerating room thermostat 9 is ON during the freezing chamber thermostat 8 is ON, and the refrigerating air blowing fan 7 when the freezing chamber thermostat 8 is OFF. ) Doesn't work either.

이러한 방식으로 회로를 구성한 이유는, 대분분의 경우, 냉동실(11)의 냉각시간이 냉장실(15)의 냉각시간보다 길게 되며, 냉동실(11)의 냉각작동이 이루어지는 동안에 냉장실(15)을 냉각시켜도 충분히 냉장실(15)의 온도를 적정 수준으로 유지할 수 있기 때문이다.The reason why the circuit is constructed in this manner is that, in most cases, the cooling time of the freezing chamber 11 is longer than that of the refrigerating chamber 15, and even if the refrigerating chamber 15 is cooled while the freezing chamber 11 is being cooled. This is because the temperature of the refrigerating chamber 15 can be sufficiently maintained at an appropriate level.

한편, 냉동실서모스탯(8) 및 냉장실서모스탯(9)은 바이메탈이나 온도변화에 따라 수축과 팽창을 하는 가스에 의해 수축 및 팽창을 하는 벨로우즈를 이용한 서모스탯 등 다양한 종류의 서모스탯이 사용될 수 있으며, 제작 방식에 따라 사용자가 설정온도를 조절할 수도 있다. 또한, 냉동실증발기 및 냉장실증발기가 병렬로 연결되어 있는 독립냉각방식 냉장고의 경우에는 냉동실 및 냉장실의 온도에 따라 각 증발기로의 냉매의 순환이 각각 다르게 단속되는데, 이러한 독립냉각방식 냉장고에서도 본 발명은 적용될 수 있다.On the other hand, the freezer thermostat (8) and the refrigerating chamber thermostat (9) can be used in a variety of thermostats, such as thermostats using a bellows that is expanded and contracted by a gas that shrinks and expands according to bimetal or temperature change. According to the manufacturing method, the user can adjust the set temperature. In addition, in the case of the independent refrigerator type refrigerator in which the freezer evaporator and the refrigerator compartment evaporator are connected in parallel, the circulation of the refrigerant to each evaporator is differently regulated according to the temperature of the freezer compartment and the refrigerator compartment. Can be.

이에 따라, 냉동실과 냉장실의 온도변화에 따라 냉동실 및 냉장실로의 냉기공급을 기계적으로 조절할 수 있으며, 마이컴과 같은 전자식 제어장치나 그에 부속되는 부품을 설치할 필요가 없고, 마이컴에 의한 제어동작을 수행시키기 위한 별도의 프로그램을 작성하지 않아도 된다.Accordingly, the supply of cold air to the freezer compartment and the refrigerating compartment may be mechanically controlled according to the temperature change of the freezer compartment and the refrigerating compartment, and there is no need to install an electronic control device such as a microcomputer or its components, and to perform a control operation by the microcomputer. You do not have to write a separate program for that.

이상 설명한 바와 같이, 본 발명에 따르면, 비교적 간단하고 저렴한 구조로 냉동실 및 냉장실의 온도제어가 가능하고 작동불량이 적은 독립냉각방식냉장고가 제공된다.As described above, according to the present invention, a freezer compartment and a refrigerating compartment temperature control in a relatively simple and inexpensive structure is provided, and an independent refrigeration type refrigerator is provided in which the malfunction is small.
