[0038] In existing car refrigerators, there is a situation where the storage compartment of the car refrigerator exchanges heat with the car cabin. Taking a five-seat, two-row car as an example, the car refrigerator is usually installed in the armrest position inside the car, that is, between the driver and the front passenger seats. In this case, the heat dissipation vent of the car refrigerator is usually located near the rear seats. When the refrigerator starts working, the heat from the condenser and compressor is exhausted to the heat dissipation vent through the condenser fan, and then into the car cabin. The temperature of the hot air from the heat dissipation vent is generally 30~40°C. When the compressor runs for a long time, the second-row users or the driver and front passenger users will clearly feel hot air blowing directly on their ankles, which is not a good experience.

[0039] The utility model provides a vehicle refrigerator, aims at reducing the air outlet temperature of the heat dissipation port of the vehicle refrigerator, reduces the heat accumulation in the vehicle cabin generated by the operation of the vehicle refrigerator, thereby improving the use experience of the user, the vehicle refrigerator is usually used on the vehicle, of course, the vehicle refrigerator can also be used independently, for example, outdoor refrigerator, below will take the vehicle refrigerator is usually installed in the armrest position in the vehicle as an example to introduce, for the convenience of understanding and illustration, in the description of the utility model in the specification Figures 1 to 9 In the description of the utility model in the specification, the solid line arrow indicates the opening.

[0040] The vehicle refrigerator generally includes the compressor type vehicle refrigerator, the thermoelectric refrigeration (semiconductor refrigeration) type vehicle refrigerator or the compression thermoelectric hybrid refrigeration etc., the compressor type vehicle refrigerator includes the direct cooling type vehicle refrigerator and the air cooling type vehicle refrigerator, the utility model mainly aims at the air cooling type vehicle refrigerator or the composite refrigeration type vehicle refrigerator with air cooling system.

[0041] Below, taking the air cooling type vehicle refrigerator as an example to expand the description.

[0042] Please refer to Figures 1 to 9 In the embodiment of the utility model, the vehicle refrigerator 10 includes the box body 100, refrigeration system 200 and water storage box 300, the box body 100 is equipped with storage cavity 101, heat dissipation air duct 102 and the heat dissipation port 102b that is communicated with heat dissipation air duct 102;Refrigeration system 200 is arranged in the box body 100 and is used to adjust the temperature of storage cavity 101;The refrigeration system 200 includes evaporator 240, condenser 220 and heat dissipation fan 230, the evaporator 240 is used to heat exchange with storage cavity 101, the condenser 220 and heat dissipation fan 230 are arranged in heat dissipation air duct 102;Water storage box 300 is arranged in heat dissipation air duct 102, the top of water storage box 300 is equipped with opening 301, and the opening 301 is communicated with the heat dissipation channel.

[0043] Among them, the box body 100 is the main frame of the vehicle refrigerator 10, and the box body 100 is also usually the installation carrier of other components of the vehicle refrigerator 10, usually, the box body 100 is used to install and fix with the vehicle main body.The box body 100 usually includes shell 120 and inner container 130, and the space is formed between the shell 120 and the inner container 130, which is used to fill the foaming material to form the heat preservation layer.The inner container 130 constructs storage cavity 101, which is used to store food or other articles, and the number of storage cavity 101 can be one or more;The shell 120 constructs heat dissipation air duct 102, or other shell and shell 120 together form the heat dissipation air duct 102.

[0044] The refrigeration system 200 is responsible for adjusting the temperature in the storage cavity 101 to a suitable low temperature state, so as to achieve the purpose of refrigeration or freezing. The refrigeration system 200 usually includes a compressor 210, a condenser 220, an evaporator 240 and the like. The compressor 210, the condenser 220 and the evaporator 240 are in communication with each other to form a refrigerant circulation heat exchange loop. Usually, the refrigeration system 200 also includes a heat dissipation fan 230. The heat dissipation fan 230 can quickly take away the heat released by the condenser 220 by forced air flow, thereby improving the heat dissipation efficiency of the condenser 220. Through rapid heat dissipation, the condenser 220 can more effectively condense the refrigerant into a liquid state. Of course, the heat dissipation requirement of the condenser 220 will be different under different ambient temperatures. The heat dissipation fan 230 can adjust the air volume according to the actual needs, so as to adapt to different working environments. The heat dissipation fan 230 can be a centrifugal fan or an axial flow fan.

[0045] The water storage box 300 is used to hold liquid. The structure of the water storage box 300 can be various, such as a regular shape like a cylinder or a square box, or an irregular shape. The opening 301 can be circular, oval or square. Here, examples are not given one by one.

[0046] Since the water storage box 300 is arranged in the heat dissipation air duct 102, the water storage box 300 is provided with an opening 301. The opening 301 is usually arranged at the upper part, for example, the opening 301 can be arranged in the upper half of the water storage box 300, preferably, the opening 301 is arranged on the top surface of the water storage box 300.

[0047] The opening 301 is in communication with the heat dissipation air duct 102. In this way, the opening 301 at the top of the water storage box 300 is in communication with the heat dissipation air duct 102, which enables the air in the heat dissipation air duct 102 to directly contact the water in the water storage box 300. The flowing air can take away the water vapor evaporated in the water storage box 300. Since evaporation absorbs heat, the temperature of the air flow in the heat dissipation air duct 102 after passing through the water storage box 300 can be reduced.

[0048] The area of the opening 301 is usually large. For example, when the opening 301 is arranged on the top surface of the water storage box 300, the area of the opening 301 is usually greater than 50% of the area of the top surface of the water storage box 300, for example, 60%, 70%, 80%, 90% or 100%. In this way, heat dissipation can be better.

[0049] For example, the water storage box 300 is arranged as a square box, the opening 301 is arranged at the top of the water storage box 300, and further, the opening 301 is arranged as an open opening. At this time, the area of the opening 301 is 100% of the area of the top surface of the water storage box 300.

[0050] It can be understood that the top of the water storage box 300 is provided with an opening 301, and liquid can be added into the water storage box 300 from the opening 301, of course, a special water adding port can also be provided to realize water adding to the water storage box 300. The liquid can be manually added by the user, or the water storage box 300 is connected to a water source through a pipeline, or the liquid can be defrosting water generated by the evaporator 240.

[0051] In the extension direction of the heat dissipation air duct 102, the water storage box 300, the condenser 220 and the heat dissipation fan 230 can be arranged in sequence, the condenser 220, the heat dissipation fan 230 and the water storage box 300 can be arranged in sequence, or the condenser 220, the water storage box 300 and the heat dissipation fan 230 can be arranged in sequence.

[0052] The technical scheme of the utility model, through setting water storage box 300 in heat dissipation air duct 102, when water storage box 300 holds liquid, the air in heat dissipation air duct 102 can directly contact with the water in water storage box 300, and the flowing air can take away the water vapor evaporated in water storage box 300, because of heat absorption of evaporation, can reduce the temperature of the airflow of heat dissipation air duct 102 after passing through water storage box 300, in this way, the outlet air temperature of the heat dissipation port 102b of the vehicle-mounted refrigerator 10 can be reduced.

[0053] In a preferred embodiment, the water storage box 300 is used to store the defrosting water generated by the evaporator 240,

[0054] In this embodiment, based on the scheme of the air-cooled vehicle-mounted refrigerator 10, the defrosting water of the evaporator 240 is further collected and stored. Since the water storage box 300 is located between the compressor 210 and the heat dissipation fan 230 of the condenser 220, the temperature of the defrosting water of the evaporator 240 is generally equivalent to the temperature inside the refrigerator, which is generally around 0-10°. When the heat dissipation fan 230 is working, it drives the airflow in the heat dissipation air duct 102 to flow, and the airflow can take away the cold energy of the relatively low-temperature water storage box 300, thereby reducing the temperature of the air discharged from the heat dissipation port 102b. At this time, based on the principle of energy conservation, the temperature of the air blown out of the heat dissipation port 102b is equivalent to the temperature inside the vehicle cabin, and at this time, the user cannot feel the direct blowing of hot air, which can improve the user experience.

[0055] In this embodiment, the water storage box 300 receives the defrosting water generated by the evaporator 240, which can solve the defrosting problem of the vehicle-mounted refrigerator 10 and reduce the outlet air temperature of the heat dissipation port. In addition, since the temperature of the defrosting water is generally low, the temperature of the heat dissipation port 102b can be further reduced.

[0056] In some embodiments, the compressor 210 is also arranged in the heat dissipation air duct 102, and the heat dissipation air duct 102 can also dissipate heat for the compressor 210. Through the secondary use of defrosting water, the heat dissipated by the compressor 210 and the condenser 220 is neutralized.

[0057] In an exemplary embodiment, the box 100 comprises a shell 120, an inner container 130, and a mounting bracket 110. The inner container 130 has the storage cavity 101. The inner container 130 is arranged in the shell 120. The evaporator 240 is arranged in the inner container 130. The inner container 130 is provided with a water collecting groove 140. The water collecting groove 140 is located below the evaporator 240 and is used to collect defrosting water generated when the evaporator 240 defrosts. The mounting bracket 110 is arranged in the shell 120. The mounting bracket 110 and the shell 120 form the heat dissipation air duct 102. The heat dissipation port 102b is arranged in the mounting bracket 110. The condenser 220, the heat dissipation fan 230, and the water storage box 300 are arranged in the mounting bracket 110. The water storage box 300 is arranged below the water collecting groove 140. The water collecting groove 140 communicates with the water storage box 300.

[0058] The inner container 130 is provided with the water collecting groove 140, and the water collecting groove 140 communicates with the water storage box 300. In this way, defrosting water generated when the evaporator 240 defrosts is collected by the water collecting groove 140 and discharged into the water storage box 300.

[0059] In an embodiment, the mounting bracket 110 comprises a bottom plate 111 and first and second side plates 112 and 113 arranged on opposite sides of the bottom plate 111. The first side plate 112 is provided with the air inlet 102a. The second side plate 113 is provided with the heat dissipation port 102b. The condenser 220 is arranged on one side of the bottom plate 111 close to the air inlet 102a. The water storage box 300 is arranged on one side of the bottom plate 111 close to the heat dissipation port 102b. The heat dissipation fan 230 is arranged on the condenser 220. The heat dissipation fan 230 is located between the condenser 220 and the water storage box 300.

[0060] The mounting bracket 110 comprises a bottom plate 111 and first and second side plates 112 and 113 arranged on the bottom plate 111. Generally, the bottom plate 111, the first side plate 112, and the second side plate 113 are connected with the shell 120. The bottom plate 111, the first side plate 112, the second side plate 113, and the shell 120 are integrally formed. Alternatively, the bottom plate 111, the first side plate 112, and the second side plate 113 are mounted on the shell 120 as an independent component. Alternatively, the bottom plate 111, the first side plate 112, and the second side plate 113 are integrally formed and then mounted on the shell 120.

[0061] The condenser 220 is arranged on the side of the bottom plate 111 of the mounting bracket 110 close to the air inlet 102a, so that the cold air of the incoming air directly contacts the condenser 220, helping the condenser 220 to dissipate heat more quickly. The heat released by the condenser 220 is quickly taken away by the fan, thereby reducing the temperature of the condenser 220 itself, helping to reduce the overall energy consumption of the system and reducing the efficiency loss caused by excessive temperature. The condenser 220 and the water storage box 300 are distributed on opposite sides of the bottom plate 111, and the heat dissipation fan 230 is located between them. The heat dissipation fan 230 takes away the hot air from the condenser 220, so that the air temperature at the heat dissipation port 102b is lower, reducing the influence of the water vapor in the evaporative water storage box 300 on the condenser 220.

[0062] In order to facilitate the rapid evaporation of water in the water storage box 300, thereby reducing the outlet air temperature of the heat dissipation port 102b, the area of the opening 301 should be as large as possible, for example, an open setting. However, in this way, when the vehicle is jolted or the inclination angle is large, the water in the water storage box 300 is easy to spill. In order to solve this problem, in an embodiment, the vehicle-mounted refrigerator 10 includes a water absorption assembly 400 arranged in the water storage box 300.

[0063] The water absorption medium of the water absorption assembly 400 is usually required to have good air permeability and water absorption, such as non-woven fabric, wet film, sponge or polyester fiber, etc. In this way, when the vehicle is jolted or the inclination angle is large, the water absorption assembly 400 can to some extent alleviate the spilling of water in the water storage box 300.

[0064] The structure of the water absorption member 410 is usually determined by its water absorption medium. For example, if it is a sponge, it usually does not need to be fixed by a mounting structure. If it is a wet film, it usually has a mounting structure. If it is a non-woven fabric, it can be fixed by a mounting structure or without a mounting structure to form a non-woven fabric water absorption module.

[0065] For example, by arranging multiple layers of non-woven fabric along the length direction at intervals, the multiple layers of non-woven fabric are connected and formed by another non-woven fabric. The non-woven fabric water absorption module can effectively seal water in the fiber gap, thereby reducing the overflow or spilling of liquid water. When the water is absorbed into the module, it will be firmly adsorbed in the fiber, maintaining a certain degree of moisture, and reducing the problem of water overflow caused by excessive water.

[0066] The non-woven fabric itself has strong water absorption, can quickly absorb water and evenly distribute it throughout the module. Due to the fiber structure and high porosity of the non-woven fabric, it can effectively hold water, thereby providing a lasting water absorption effect. The structure of the non-woven fabric makes it have good air permeability. After the water is absorbed, it can quickly evaporate outward through the open structure of the non-woven fabric, which helps to accelerate the evaporation speed of water. In this embodiment, the use of non-woven fabric as a water absorption medium helps to accelerate the cooling of the heat dissipation air duct 102.

[0067] Further, the water absorption assembly 400 is exposed to the opening 301, that is, the water absorption assembly 400 is exposed to the liquid surface of the water storage box 300. Due to the good air permeability of the water absorption medium of the water absorption assembly 400, the exposure of the water absorption assembly 400 to the opening 301 can accelerate the evaporation of the liquid in the water storage box 300, thereby further reducing the outlet air temperature of the heat dissipation port 102b.

[0068] In an exemplary embodiment, as shown in Figure 5 The water absorption assembly 400 includes a water absorption element 410, and the water absorption element 410 is floating in the water storage box 300, and part of the water absorption element 410 is exposed to the opening 301.

[0069] In this embodiment, the water absorption element 410 is floating in the water storage box 300, so that the water absorption element 410 can always float on the water surface when the water level is low or fluctuates. In this way, the water absorption element 410 can effectively reduce the splashing or outflow of water, especially in the case of sudden braking of the vehicle, jolting of the vehicle, or driving on a steep slope, which helps to prevent water from spilling out of the water storage box 300.

[0070] Part of the water absorption element 410 is exposed to the opening 301 of the water storage box 300, which can make the water more evenly distributed and quickly absorbed or evaporated, while avoiding too much water being directly exposed to the outside air, thereby reducing the risk of water overflow. When the water level is too high, the floating water absorption element 410 will float on the water surface, preventing the water level from rising to the overflow position and further reducing the possibility of water outflow.

[0071] The water absorption element 410 usually has a large surface area, which can allow more water to evaporate into the air by absorbing water and being retained in the opening 301 of the water storage box 300, thereby effectively accelerating the evaporation process of water. In a high-temperature or low-humidity environment, the evaporation speed of water will be significantly improved.

[0072] In another exemplary embodiment, the water absorption assembly 400 includes a plurality of water absorption elements 410, and the plurality of water absorption elements 410 are stacked along the depth direction of the water storage box 300, and the water absorption element 410 on the top surface is exposed to the opening 301.

[0073] In this embodiment, by stacking multiple water absorption members 410, the total surface area of the water absorption members 410 can be increased in a limited space, so that water can be absorbed in a larger area, which helps to better maintain the stable water level of the water storage box 300; the water absorption members 410 at the top are exposed to the opening 301 of the water storage box 300, so that when the water level of the water storage box 300 is high, water will not overflow, but will be absorbed by the exposed water absorption members 410 and kept within the water level range. The water absorption members 410 located at the opening 301 of the water storage box 300 are exposed to the outside air and directly contact the air, which can accelerate the evaporation process of water. As the air temperature in the heat dissipation air duct 102 can be effectively regulated due to the heat exchange between the heat dissipation air duct 102 and the vehicle cabin, this arrangement can also regulate the humidity of the vehicle cabin.

[0074] In yet another exemplary embodiment, referring to Figure 6 and Figure 7 , the water absorption assembly 400 includes a plurality of water absorption members 410, which are arranged at intervals along a first direction, and the first direction is arranged at an angle to the extension direction of the heat dissipation air duct 102; one end of the plurality of water absorption members 410 is located at the water storage box 300, and the other end of the plurality of water absorption members 410 is exposed to the opening 301.

[0075] The first direction is the arrangement direction of the water absorption members 410, which is arranged at an angle to the extension direction of the heat dissipation air duct 102, mainly to reduce the resistance of the water absorption members 410 to the airflow, and also to increase the contact area between the water and the air to promote water evaporation.

[0076] One end of the water absorption member 410 is located at the water storage box 300, and the other end of the water absorption member 410 is exposed to the opening 301 and directly contacts the outside air, which can promote the evaporation of water. Water evaporates from the surface of the water absorption member 410 into the air, significantly increasing the evaporation speed. In particular, when the water absorption members 410 are arranged at an angle, water can be more evenly distributed at the opening 301, improving the evaporation efficiency.

[0077] The technical solution of this embodiment can increase the contact area between the airflow and the water absorption members 410, thereby enhancing the evaporation effect. When the airflow passes through the air duct, the evaporation of water is accelerated.
