[0049] The technical scheme in the embodiment will be described clearly and completely below in conjunction with the accompanying drawings in the embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all of the embodiments. Based on the embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] like Figure 1 and Figure 2 As shown, some embodiments provide a vehicle refrigerator configured to be installed on a vehicle, and the vehicle refrigerator includes a box body 1, a refrigeration system 3 and a heating system 2.

[0052] At least one storage chamber 11 is formed in the box body 1 .

[0053] like Figure 2 As shown, the refrigeration system 3 includes a compressor 33 , an evaporator 31 and a condenser 32 , and the refrigeration system 3 is configured to refrigerate one of the at least one storage chamber 11 . The refrigeration system 3 also includes a throttling element 34 .

[0054] like Figure 1 As shown, the heating system 2 includes a flow channel 21, which is disposed at the housing 1. The flow channel 21 is configured to pass coolant to heat one of the at least one storage chamber 11, and the coolant is configured to come from a coolant circulation system 7 of the vehicle.

[0055] The coolant in the coolant circulation system 7 is used to cool the vehicle's engine. The coolant in the coolant circulation system 7 is used to provide the waste heat from the vehicle's engine to the vehicle refrigerator, thereby achieving heating and insulation functions. This can not only satisfy the heating and insulation effects of the vehicle refrigerator, but also does not increase energy consumption.

[0056] The vehicle refrigerator provided in the embodiment of the present disclosure realizes fast and powerful refrigeration, ice making and preservation functions through the refrigeration system 3, realizes heating and insulation functions through the heating system 2, and by introducing the coolant in the vehicle's coolant circulation system 7 and utilizing the waste heat in the coolant, the vehicle refrigerator has the functions of heating and insulation without increasing energy consumption, thereby better meeting customer needs.

[0057] In some embodiments, the heating system 2 further includes a first flow control valve 22, which is disposed at the inlet end of the flow channel 21. The first flow control valve 22 is used to control the flow rate of the coolant introduced from the coolant circulation system 7 into the flow channel 21 of the vehicle refrigerator to control the temperature of the vehicle refrigerator.

[0058] In some embodiments, the heating system 2 further includes a second flow control valve 23, which is disposed at the outlet end of the flow channel 21. When the first flow control valve 22 is closed, the second flow control valve 23 can be opened to drain the coolant in the flow channel 21, and then the vehicle refrigerator can be cooled by the refrigeration system 3.

[0059] In some embodiments, the heating system 2 further includes a pump 24, which is disposed in the flow channel 21 and is located downstream of the first flow control valve 22. The pump 24 is used to provide power to allow the coolant in the coolant circulation system 7 to enter the flow channel 21. When the first flow control valve 22 is closed, the second flow control valve 23 can be opened, and the coolant in the flow channel 21 can be emptied by the pump 24 to provide power, and then the vehicle refrigerator can be cooled by the refrigeration system 3.

[0060] Optionally, the pump 24 comprises an impeller pump. When the pump 24 is turned off, the coolant in the flow channel 21 can also flow out through the pump 24. The impeller in the impeller pump rotates freely under the flow force of the coolant.

[0061] In some embodiments, Figure 3 As shown, the flow channel 21 is disposed at the bottom of the storage chamber 11 .

[0062] In other embodiments, the flow channel 21 is disposed on the outer periphery of the storage chamber 11 .

[0063] The arrangement of the flow channel 21 can be determined according to the specific volume and heating requirements of the vehicle refrigerator. For a vehicle refrigerator with only one storage chamber 11, the storage chamber 11 has both cooling and heating functions. Due to space limitations, in order to simultaneously arrange the evaporator 31 in the cooling system 3 and the flow channel 21 in the heating system 2 in the storage chamber 11; the evaporator 31 adopts a tubular evaporator 311, which is arranged around the circumference of the storage chamber 11, and the flow channel 21 is arranged at the bottom of the storage chamber 11. Of course, in the case where the storage chamber 11 only has a heating function, the flow channel 21 can also be arranged on the outer periphery of the storage chamber 11.

[0064] In some embodiments, Figure 5 As shown, at least one storage chamber 11 includes a first storage chamber 101 and a second storage chamber 102 , the refrigeration system 3 is configured to cool the first storage chamber 101 , and the flow channel 21 is configured to pass cooling liquid to heat the second storage chamber 102 .

[0065] In some embodiments, the evaporator 31 includes a tubular evaporator 311, which is arranged around the circumference of the first storage chamber 101 or is arranged at the bottom of the first storage chamber 101, and the flow channel 21 is arranged around the circumference of the second storage chamber 102 or is arranged at the bottom of the second storage chamber 102.

[0066] In some embodiments, the arrangement density of the pipes in the upper part of the tube evaporator 311 is greater than that in the lower part. The arrangement density of the flow channels in the upper part of the flow channel 21 is less than that in the lower part.

[0067] Since hot air rises and cold air sinks, in order to ensure that the temperature of the upper part of the vehicle refrigerator can meet the requirements and the temperature in the whole box is uniform, the pipes of the tubular evaporator 31 are arranged densely on the top and sparsely on the bottom, and the flow channel 21 is arranged sparsely on the top and densely on the bottom.

[0068] In some embodiments, Figure 4 As shown, at least one storage chamber 11 includes a first storage chamber 101 , the refrigeration system 3 is configured to cool the first storage chamber 101 , and the flow channel 21 is configured to pass cooling liquid to heat the first storage chamber 101 .

[0069] In some embodiments, the evaporator 31 includes a tubular evaporator 311 , which is disposed around the circumference of the first storage chamber 101 , and the flow channel 21 is disposed at the bottom of the first storage chamber 101 .

[0070] In some embodiments, the arrangement density of the tubes in the upper portion of the tube evaporator 311 is greater than the arrangement density of the tubes in the lower portion.

[0071] Since hot air rises and cold air sinks, in order to ensure that the temperature of the upper part of the vehicle refrigerator can meet the requirements and the temperature in the whole box is uniform, the pipes of the tube evaporator 31 are arranged densely on the top and sparsely on the bottom.

[0072] In some embodiments, the flow channel 21 includes a flow channel formed in a blow plate or a flow channel formed in a tube plate.

[0073] Some embodiments further provide a vehicle, which includes an engine, a coolant circulation system 7, a first pipeline 41 and the vehicle refrigerator in the above embodiment.

[0074] The coolant circulation system 7 is configured to cool the engine. The coolant circulation system 7 is connected to the flow channel 21 of the vehicle refrigerator through the first pipeline 41. Figure 1 As shown, part of the coolant in the coolant circulation system 7 enters the flow channel 21 of the vehicle refrigerator to heat the vehicle refrigerator.

[0075] The vehicle refrigerator is heated by using the coolant in the coolant circulation system 7. The coolant in the coolant circulation system 7 passes through the engine to cool the engine and take away the heat. The hot coolant enters the flow channel 21 of the vehicle refrigerator to provide a heat source, so that the vehicle refrigerator has a heating function without increasing energy consumption.

[0076] The vehicle provided in the embodiment of the present disclosure utilizes its own coolant circulation system 7 to provide waste heat from the engine to the vehicle refrigerator for heating and heat preservation, thereby better meeting customer needs and improving product market competitiveness.

[0077] In some embodiments, the vehicle further includes an onboard air conditioner and a second pipe 42, and the coolant circulation system 7 is connected to the onboard air conditioner through the second pipe 42, so that part of the coolant in the coolant circulation system 7 enters the onboard air conditioner to heat the onboard air conditioner.

[0078] The coolant in the coolant circulation system 7 cools down the vehicle engine. After the coolant absorbs heat, part of the coolant enters the vehicle air conditioner to heat the air conditioner.

[0080] In some embodiments, the vehicle also includes a first control valve 61, which is disposed at the connection between the first connector 51 and the first pipeline 41, and is used to control whether coolant is introduced into the first pipeline 41, and to control the flow rate of coolant entering the first pipeline 41.

[0081] In some embodiments, the vehicle also includes a second connector 52, a third pipeline 43 and a fourth pipeline 44, the third pipeline 43 is connected to the outlet end of the flow channel 21, the fourth pipeline 44 is connected to the coolant discharge end of the vehicle air conditioner, the second connector 52 is connected to the coolant circulation system 7, the third pipeline 43 and the fourth pipeline 44, and the second connector 52 is configured to direct the coolant in the coolant circulation system 7 to the third pipeline 43 and the fourth pipeline 44.

[0082] In some embodiments, the vehicle further includes a second control valve 62 , which is disposed at the connection between the second connector 52 and the third pipeline 43 , and is used to control whether to withdraw the coolant in the third pipeline 43 .

[0083] Optionally, the first joint 51 and the second joint 52 are both three-way joints.

[0084] Some embodiments further provide a control method for the above-mentioned vehicle refrigerator, which includes:

[0085] Turning on the refrigeration system 3 to cool one of the at least one storage chambers 11;

[0086] The coolant is introduced into the flow channel 21 of the heating system 2 to heat one of the at least one storage chamber 11 , and the coolant comes from the coolant circulation system 7 of the vehicle.

[0087] In some embodiments, the at least one storage chamber 11 of the vehicle refrigerator includes a first storage chamber 101 and a second storage chamber 102, and the control method includes:

[0088] Turn on the refrigeration system 3 to cool the first storage chamber 101;

[0089] The coolant is passed into the flow channel 21 to heat the second storage chamber 102 .

[0090] In some embodiments, the at least one storage chamber 11 of the vehicle refrigerator includes a first storage chamber 101, and the control method includes:

[0091] When heating is required, the refrigeration system 3 is turned off, and the coolant is passed into the flow channel 21 to heat the first storage chamber 101;

[0092] When refrigeration is required, the flow of coolant into the flow channel 21 is stopped, and the refrigeration system 3 is turned on to cool the first storage chamber 101 .

[0093] In some embodiments, at least one storage chamber 11 of the vehicle refrigerator includes a first storage chamber 101, the refrigeration system 3 is configured to cool the first storage chamber 101, the flow channel 21 is configured to pass coolant to heat the first storage chamber 101, a first flow control valve 22 is provided at the inlet end of the flow channel 21, and a second flow control valve 23 and a pump 24 are provided at the outlet end of the flow channel 21. The control method of the vehicle refrigerator includes:

[0094] When heating is required, the refrigeration system 3 is turned off, the first flow control valve 22 and the second flow control valve 23 are opened, and the pump 24 is operated; the hot coolant enters the flow channel 21, and the temperature in the first storage chamber 101 is increased by heat transfer, and when the temperature in the first storage chamber 101 reaches the set value, the pump 24 is turned off;

[0095] When refrigeration is needed, the first flow control valve 22 is closed, the second flow control valve 23 is opened, and the pump 24 is operated. After a preset time, the second flow control valve 23 and the pump 24 are closed to discharge the coolant in the flow channel 21, and then the refrigeration system 3 is turned on to cool the first storage chamber 101.

[0096] In some embodiments, the inlet end of the flow channel 21 is connected to the first joint 51 through the first pipeline 41, and the outlet end of the flow channel 21 is connected to the second joint 52 through the third pipeline 43. The first joint 51 and the second joint 52 are respectively connected to the outlet and inlet ends of the coolant circulation system 7.

[0097] The first control valve 61, the second control valve 62, the first flow control valve 22, and the second flow control valve 23 are opened to form a loop between the heating system 2 of the vehicle refrigerator and the coolant circulation system 7 of the vehicle.

[0098] In some embodiments, the vehicle refrigerator further includes a controller, and the controller is configured to implement the above-mentioned control method of the vehicle refrigerator.

[0099] In some embodiments, the vehicle refrigerator further includes a controller, a display and a temperature sensor. The temperature sensor is used to detect the temperature in the storage chamber 11. The controller is electrically connected to the first flow control valve 22, the second flow control valve 23 and the pump 24.

[0100] According to the difference between the set temperature on the display and the temperature detected by the temperature sensor in the storage chamber 11 , the flow rate of the coolant in the flow channel 21 is adjusted by the first flow control valve 22 .

[0101] When the refrigerator needs to be heated and kept warm, the heating mode is entered through the function key on the display, and the temperature is set on the display. At this time, the controller controls the compressor 33 in the refrigeration system 3 to stop, the first flow control valve 22 and the second flow control valve 23 to open, and the pump 24 starts to run; the hot coolant enters the flow channel 21, and the temperature in the storage chamber 11 is increased through heat transfer. The temperature is sensed by the temperature sensor in the vehicle refrigerator. When the temperature reaches the set value, the controller controls the pump 24 to close, and the pump 24 rotates freely. The controller controls the first control valve 61 and the second control valve 62 to close; when the temperature is lower than the set value, the controller controls the first control valve 61 and the second control valve 62 to open; and the storage chamber 11 is kept at the set temperature.

[0102] When the user has a cooling demand, the user enters the cooling mode through the display function key, sets the temperature on the display, and the controller controls the first flow control valve 22 to close, the second flow control valve 23 to open, and the pump 24 to start. After reaching the preset time (for example: 1 minute), the second flow control valve 23 and the pump 24 are closed. At this time, the coolant in the flow channel 21 has been basically emptied (because the use range of the coolant is basically between -30°C and 100°C, so even if there is a small amount of coolant in the flow channel 21, it will not cause ice blockage and affect the next heating demand). The compressor of the car refrigerator is running, and the refrigerant cools the storage chamber 11 through the tubular evaporator 311 to meet the cooling demand. The temperature is sensed by the temperature sensor in the car refrigerator. When the temperature reaches the set value, the controller will control the compressor to stop. When the temperature is higher than the set value, the controller will control the compressor to start; keep the storage chamber 11 at the set temperature.

[0103] The above embodiment is a control method for a single storage chamber of a vehicle refrigerator having both heating and cooling functions; when a single storage chamber of the vehicle refrigerator has both heating and cooling functions, the display is provided with heating and cooling temperature adjustment buttons respectively; when heating is required, the single storage chamber is controlled by the heating temperature adjustment button, and when cooling is required, the single storage chamber is controlled by the cooling temperature adjustment button; the heating and cooling functions need to be switched; the user can adjust the single storage chamber to have cooling or heating functions as needed, and a vehicle refrigerator with a single storage chamber having both heating and cooling functions can reduce the volume and save vehicle space.

[0104] For a storage compartment of a car refrigerator with a heating function and another storage compartment with a cooling function, the display is provided with heating and cooling temperature adjustment buttons respectively; the heating temperature adjustment button controls the storage compartment with the heating function, and the cooling temperature adjustment button controls the storage compartment with the cooling function; there is no need to switch between heating and cooling; the user can place food in the storage compartment with the heating function or the storage compartment with the cooling function as needed.
