[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0017] like Figure 1-4 As shown, the utility model provides a detachable vehicle-mounted dual-purpose refrigeration device, including a refrigeration unit 1, the refrigeration unit 1 includes a compressor 9, a condenser 8 and a refrigeration chamber 10, the refrigeration chamber 10 is provided with an exhaust port 5 and a return air port 6, an evaporator 12 and a heating component 11 are installed in the flow channel between the exhaust port 5 and the return air port 6 inside the refrigeration chamber 10, the evaporator 12 and the compressor 9 and the condenser 8 form a circulation loop, and also include an insulation box 2 and a cold air panel 3, one of the insulation box 2 and the cold air panel 3 is detachably connected to the refrigeration unit 1, and the exhaust port 5 and the return air port 6 are correspondingly connected to the insulation box 2 or the cold air panel 3.
[0018] Specifically, the evaporator 12 can cool the air flow through the circulation channel between the exhaust port 5 and the return air port 6. The air blown out from the exhaust port 5 is the low-temperature air flow. When the insulated box 2 is connected to the refrigeration unit 1, the refrigeration unit 1 delivers cold air into the insulated box and brings back the heated hot air, thereby circulating to ensure that the temperature in the insulated box 2 continues to drop until it reaches the set temperature. In this way, the insulated box 2 can be used as a refrigerator.
[0019] When the cold air panel 3 is connected to the refrigeration unit 1 , the refrigeration unit 1 inputs cold air to the integrated cold air panel, and the cold air passes through the cold air panel 3 and is sent to the outside.
[0020] In some embodiments, the refrigeration unit 1 is provided with an electric control integrated device 4, which includes a display panel and a control mainboard, and the control mainboard is electrically connected to the compressor 9 and the heating component 11. The refrigeration unit 1 is provided with a return air temperature sensor electrically connected to the control mainboard, and a fan 7 is installed on the inner side of the exhaust port 5, and the fan 7 is electrically connected to the control mainboard. The evaporator 12 is provided with a defrost temperature sensor, and the defrost temperature sensor is electrically connected to the control mainboard.
[0021] After the insulation box 2 is connected to the refrigeration unit 1, when the return air temperature sensor detects that the temperature of the insulation box 2 has reached the set temperature, the temperature value is returned to the control main board, and the control main board controls to stop the operation of the compressor 9 according to the rules. When the refrigerator temperature sensor detects that the temperature of the insulation box 2 has reached the preset startup temperature, the temperature value is returned to the control main board, and the control main board controls to start the operation of the compressor 9 according to the rules. This process is repeated to ensure that the temperature in the insulation box fluctuates around the set temperature. During the refrigeration process, the evaporator surface temperature T1 is continuously detected. When T1 is less than the set temperature T2, the defrost state is entered. At this time, the compressor 9 stops and the defrost heating system starts to work until T1 is greater than the set temperature T3, at which time the defrost heating system stops working, the compressor starts, and the normal refrigeration state is entered.
[0022] When the cold air panel 3 is connected to the refrigeration unit 1, the cold air panel 3 is provided with a return air port to absorb the surrounding hot air and return it to the evaporator for cooling. This is repeated. The refrigeration process continuously detects the evaporator surface temperature T1. When T1 is less than the set temperature T4, it enters the defrosting state. At this time, the compressor 9 stops and the defrosting heating system starts working. When T1 is greater than the set temperature T5, the defrosting heating system stops working, the compressor starts, and it enters the normal refrigeration state. The cold air panel and the insulation box can only be configured for use, and cannot be used at the same time.
[0023] A defrost water receiving tray is installed at the lower part of the evaporator 12, and the defrost generated by defrosting is discharged into the defrost water receiving tray for evaporation, thereby solving the drainage problem.
[0024] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
[0025] In addition, in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.
[0026] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0027] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
