[0032] In the relevant existing technology, the defrosting of the evaporator assembly of the car refrigerator will produce defrost water. When there is a lot of defrost water, it is easy to overflow the evaporator into the refrigerator's storage space when the vehicle is bumpy or tilted at a large angle, which may damage the items stored in the storage space.
[0033] This utility model proposes a vehicle-mounted refrigerator designed to alleviate the problem of spillage from the evaporator into the refrigerator's storage space when encountering bumpy roads or significant tilting, thus damaging the stored items. This vehicle-mounted refrigerator can be a compressor-type refrigerator, a thermoelectric (semiconductor refrigeration) type refrigerator, or a hybrid compressor-thermoelectric refrigeration system. Compressor-type refrigerators include direct-cooling and air-cooling types; the following explanation will focus on an air-cooling type refrigerator.
[0034] Please see Figures 1 to 3 In one embodiment of the present invention, the vehicle refrigerator 10 includes a cabinet 100, a refrigeration system, and an evaporating dish 300. The cabinet 100 is provided with a storage cavity. The refrigeration system is located in the cabinet 100 and is used to regulate the temperature of the storage cavity. The refrigeration system includes an evaporator assembly 200. The evaporating dish 300 is located in the cabinet 100 and below the evaporator assembly 200. It is used to collect and evaporate the defrost water generated when the evaporator assembly 200 defrosts. The bottom wall of the evaporating dish 300 is provided with a plurality of recesses 310.
[0035] The cabinet 100 is the main frame of the vehicle refrigerator 10. The cabinet 100 forms a storage cavity for storing food or other items. The cabinet 100 is usually also the mounting carrier for other components of the vehicle refrigerator 10. Typically, the cabinet 100 is also used for installation and fixation to the vehicle body.
[0036] The refrigeration system is responsible for regulating the temperature inside the storage cavity to maintain it at a suitable low temperature, thereby achieving the purpose of refrigeration or freezing. A refrigeration system typically includes components such as a compressor, condenser, and evaporator. The compressor, condenser, and evaporator are interconnected to form a refrigerant circulation heat exchange loop. Of course, in an extended embodiment of this example, by incorporating valves and piping, the refrigeration system can also be used as a heating system.
[0037] The evaporator assembly 200 is used to exchange heat with the air inside the storage cavity, thereby reducing the temperature of the storage cavity. In this embodiment, it may include an evaporator and an evaporating fan, or an evaporator and a piping assembly, or an evaporator, an evaporating fan, and a piping assembly. During the defrosting process, the evaporator of the evaporator assembly 200 will produce frost water, which needs to be effectively drained. Defrosting of the evaporator at this location can be achieved by adding a heating assembly 600, or by combining a valve and a piping assembly to convert the evaporator at this location into a condenser, thereby causing the refrigerant to condense and release heat, thus achieving defrosting.
[0038] Evaporating dish 300 is used to collect defrost water generated by evaporator assembly 200 during the defrosting process. Evaporating dish 300 is positioned below evaporator assembly 200, which can be understood as directly below. Of course, it can also be positioned according to the shape of housing 100. For example, the position of evaporating dish 300 should be such that all defrost water from the evaporator can enter evaporating dish 300.
[0039] Furthermore, the bottom wall of the evaporating dish 300 is provided with multiple recesses 310. This should be understood as the bottom wall of the evaporating dish 300 referring to the inner wall surface of the bottom of the evaporating dish 300. Figure 1 or Figure 2 As shown, the bottom wall of the evaporating dish 300 has multiple recesses 310, which can be understood as being formed by the outward concavity of the bottom wall of the evaporating dish 300. The recesses 310 can have various shapes; defined by their cross-section, they can be semi-circular, triangular, fan-shaped, etc.; defined by their external shape, they can be block-shaped, strip-shaped, or ring-shaped. The number of evaporating portions can be two, three, four, five, six, or more. Thus, by providing multiple recesses 310 on the bottom wall of the evaporating dish 300, the contact area of the defrosting water can be increased, thereby increasing the evaporation rate of the water. These recesses 310 help accelerate the evaporation of the defrosting water, and to a certain extent, can alleviate the problem of excessive water accumulation in the evaporating dish 300. This can prevent the water from easily overflowing into the refrigerator's storage space when encountering bumps or significant vehicle tilt, thus avoiding damage to the items stored in that space.
[0040] It is worth mentioning that the multiple recesses 310 of the evaporating dish 300 also increase the volume of the evaporating dish 300. For example, the multiple recesses 310 of the evaporating dish 300 can be combined with the arrangement of other devices in the cabinet 100 at the evaporating dish 300. By embedding the multiple recesses 310 into the gaps between these other devices, the problem of excessive water accumulation can be alleviated when the amount of defrosting water is constant. This can alleviate the problem of water easily overflowing from the evaporating dish 300 into the refrigerator's storage space when encountering vehicle bumps or a large vehicle tilt, thus preventing damage to the items stored in the storage space.
[0041] The technical solution of this utility model is to provide multiple recesses 310 on the bottom wall of the evaporating dish 300, thereby increasing the volume of the evaporating dish 300 and the defrosting evaporation area, which can alleviate the problem of excessive water accumulation. This can also alleviate the problem that when encountering vehicle bumps or when the vehicle is tilted at a large angle, the evaporating dish 300 is likely to overflow into the refrigerator's storage space and damage the items stored in the storage space.
[0042] In one embodiment, the box body 100 is provided with a door 110 for sealing or opening the storage cavity, so that the left and right directions of the box body 100 are defined facing the front of the box body 100. Among the plurality of recesses 310, at least one of the recesses 310 extends along the left and right directions of the box body 100.
[0043] The box 100 is provided with a cover or a door 110 for opening the storage cavity. In other words, by providing a closed cover or an openable door 110, the box 100 can be easily opened to allow items to enter and exit the storage cavity.
[0044] Facing the door 110, the left and right directions of the cabinet 100 are defined. The position of the door 110 determines the front position of the car refrigerator 10. In this embodiment, the door 110 serves as a reference point to clarify the left and right directions of the cabinet 100, facilitating the positioning of the extension direction of the recess 310. When the car refrigerator 10 is applied to a vehicle, the driver is used as the reference, referring to the driver's left and right directions. Of course, in this embodiment, a vertical left-right relationship is not emphasized; it can be a relationship with a certain angle. For example, please refer to... Figure 3 The left and right directions can be like Figure 3 As shown.
[0045] Because the height of the recess 310 is relatively low, water flows downhill. When encountering vehicle bumps or situations where the vehicle is tilted at a large angle, the recess 310, which extends in the left and right direction, can play a buffering role to a certain extent.
[0046] In this embodiment, by extending at least one of the recesses 310 along the left and right directions of the cabinet 100, the recesses 310 extending along the left and right directions can play a buffering role to a certain extent when encountering vehicle bumps or situations with a large tilt, thereby further alleviating the problem of overflowing the evaporation dish 300 into the refrigerator's storage space and damaging the items stored in the storage space.
[0047] Furthermore, each of the recesses 310 extends in the left-right direction, and the plurality of recesses 310 are arranged at intervals in the front-back direction; in this way, multiple buffer sections can be formed, thereby further alleviating the problem of overflowing the evaporation dish 300 into the refrigerator's storage space and damaging the items stored in the storage space.
[0048] In one embodiment, at least one of the plurality of recesses 310 is arranged in a ring shape. Thus, when encountering vehicle bumps, the ring-shaped recess 310 can better form multiple buffer sections extending in all directions, thereby further mitigating the problem of spillage from the evaporator dish 300 into the refrigerator's storage space and damaging the items stored therein.
[0049] In one embodiment, the vehicle refrigerator 10 includes a water storage box 400, and at least one of the plurality of recesses 310 is connected to the water storage box 400 via a drain pipe 500, so that the evaporating dish 300 and the water storage box 400 are in communication.
[0050] The drain pipe 500 can be independently installed or integrated with the evaporating dish 300. The water storage box 400 mainly stores the defrost water generated in the vehicle refrigerator 10. It is connected to the water storage box 400 through at least one of the recesses 310 via the drain pipe 500. The drain pipe 500 connects the recesses 310 and the water storage box 400 to form a passage, so that the defrost water at the evaporating dish 300 can flow from the evaporating dish 300 into the water storage box 400 through the recesses 310. This further increases the storage space for defrost water in the vehicle refrigerator 10, thereby further alleviating the problem of overflowing from the evaporating dish 300 into the refrigerator's storage space and damaging the items stored in that space.
[0051] In some embodiments, a pressure switch is provided in the flow path between the first recess 310 and the water storage box 400, and the pressure switch is used to control the opening and closing of the drain pipe 500.
[0052] The pressure switch is normally closed. When the defrost water in the evaporating dish 300 accumulates to a certain amount, the pressure switch is opened, and the defrost water in the evaporating dish 300 is discharged into the water storage box 400. In this way, a certain amount of defrost water can be carried into the storage cavity by the evaporator during normal cooling, so that the storage cavity will not become too dry.
[0053] In one embodiment, the plurality of recesses 310 includes a first recess 310, which has the greatest depth and is connected to the water storage box 400 via the drain pipe 500. The water storage box 400 is generally located below the evaporating dish 300, which reduces the length of the drain pipe 500.
[0054] In one embodiment, each of the recesses 310 is connected to the water storage box 400 via the drain pipe 500. Thus, the technical solution of this embodiment can accelerate the rate at which defrost water enters the water storage box 400, providing significant assistance when there is an excess of defrost water.
[0055] In one embodiment, the housing 100 includes an outer shell and an inner liner, the inner liner being disposed within the outer shell. The inner liner includes an inner shell and an air duct partition disposed within the inner shell, the air duct partition dividing the inner shell into an installation cavity and a storage cavity. The air duct partition has an air outlet and an air return outlet respectively connecting the installation cavity and the storage cavity, forming a circulating air duct between the installation cavity, the air outlet, the storage cavity, and the air return outlet. An evaporator assembly 200 and an evaporating dish 300 are disposed within the inner shell, the evaporator assembly 200 and the evaporator being located within the installation cavity. A water storage box 400 is disposed within the outer shell, the water storage box 400 being located between the outer shell and the inner liner.
[0056] In one embodiment, the vehicle refrigerator 10 further includes a heating component 600 disposed in the mounting cavity.
[0057] The heating component 600 is located in the mounting cavity, and the evaporator of the evaporator assembly 200 is also located in the mounting cavity. The function of the heating component 600 is to provide heat energy. By heating the mounting cavity, the temperature of the mounting cavity rises. Since the evaporator of the evaporator assembly 200 is also located in the mounting cavity, as the temperature of the mounting cavity rises, the frost layer on the surface of the evaporator melts into water.
[0058] The heating element 600 typically transfers heat to the surface of the evaporator through a resistance heater, heat pipe, or other type of heating device to quickly melt the frost layer. Furthermore, by placing the heating element 600 inside the mounting cavity, the heating element 600 can be kept closer to the evaporator, or the heating element 600 can be placed directly on the evaporator.
[0059] This utility model also proposes a vehicle, which includes a vehicle body and a vehicle-mounted refrigerator 10, wherein the vehicle-mounted refrigerator 10 is disposed in the vehicle body. The specific structure of the vehicle-mounted refrigerator 10 is as described in the above embodiments. Since this vehicle adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
[0060] The vehicle mentioned can be a motorhome, luxury bus, or other self-driving tour vehicle. The vehicle typically includes a vehicle body, which usually comprises a chassis, engine, transmission system, braking system, steering system, running system, fuel system, cooling system, electrical instrumentation system, and safety protection devices.
[0061] The vehicle body is the main part of the vehicle, consisting of the roof, floor, side walls, and doors. Its main function is to provide a cabin for passengers to sit in.
[0062] In some embodiments, the vehicle cabin has a driver's seat and a passenger seat, and the vehicle refrigerator 10 is located between the driver's seat and the passenger seat.
[0063] In one embodiment, the vehicle body has a width direction, and at least one of the plurality of recesses 310 extends along the width direction.
[0064] The width direction of the vehicle body can be understood as the direction in which the driver's seat and passenger seat are arranged.
[0065] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model.
