Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of refrigerators, and in particular relates to a forced convection cooling and heating vehicle-mounted refrigerator. Background Art
[0002] At present, most of the outdoor refrigerators in vehicles are direct cooling refrigerators. However, direct cooling refrigerators can only use natural convection inside the refrigerator, and the heat transfer efficiency is very low. Therefore, the cooling speed is generally very slow, especially when items are placed in the refrigerator, which will cause the cooling time to be too long, thus greatly affecting the user experience. If the vehicle refrigerator is made into an indirect air-cooled refrigerator, the air-cooled refrigerator evaporator module will occupy most of the box volume, and the discharge of condensed water formed by the defrosting of the air-cooled refrigerator evaporator in the vehicle refrigerator still cannot be solved. Utility Model Content
[0003] To solve the problems mentioned in the above background technology, the purpose of the utility model is to provide a forced convection vehicle refrigerator, which circulates the air in the box, increases the refrigeration speed and avoids the generation of defrost water.
[0004] The utility model discloses a forced convection cooling and heating vehicle refrigerator, comprising a compressor, a condenser, a drying filter, an evaporator, a capillary tube, a refrigerator liner, a refrigerator shell, a condenser heat dissipation fan, and an in-box turbulence fan; the compressor is installed on the rear side of the refrigerator shell through a bracket, the compressor is connected to the condenser, the condenser heat dissipation fan is installed on the side wall of the condenser, the condenser is connected to the capillary tube through the drying filter, the capillary tube is connected to the evaporator, the outlet of the evaporator is connected to the compressor, the refrigerator liner is installed inside the refrigerator shell, a groove is provided on the upper side of the refrigerator liner, and the in-box turbulence fan is installed in the groove.
[0005] Preferably, the groove outlet of the refrigerator inner tank is inclined to serve as a wind guide.
[0006] Preferably, a heating film is installed in the refrigerator liner.
[0007] Preferably, a defrost heating wire is installed on the upper part of the turbulence fan in the box.
[0008] Preferably, a compressor driving module is installed on the side wall of the bracket, and the compressor driving module is electrically connected to the compressor.
[0009] Preferably, the bracket is L-shaped.
[0010] Preferably, a refrigerator door is mounted on the front side of the refrigerator housing via a rotating shaft.
[0011] Preferably, a display operation panel is installed on the upper side of the refrigerator door.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] Adding a fan to a direct cooling refrigerator can circulate the air inside the box, which increases the refrigeration speed while avoiding the generation of defrost water. At the same time, the refrigerator can also be a heating refrigerator, which also increases the heating efficiency. The fan can be designed as a hidden structure, which will not affect the original design capacity, and can greatly improve the user experience and practicality of the product.

[0023] like Figure 1 , Figure 2 As shown, this specific embodiment adopts the following technical scheme: it includes a compressor 1, a condenser 2, a drying filter 3, an evaporator 4, a capillary 5, a refrigerator liner 8, a refrigerator shell 9, a condenser heat dissipation fan 10, and an in-box turbulence fan 11; the rear side of the refrigerator shell 9 is equipped with a compressor 1 through a bracket, the compressor 1 is used for refrigeration, and is used in conjunction with the condenser 2, the drying filter 3, the evaporator 4, the capillary 5, and the condenser heat dissipation fan 10, the compressor 1 is connected to the condenser 2, the condenser heat dissipation fan 10 is installed on the side wall of the condenser 2, the condenser heat dissipation fan 10 is used for heat dissipation, the condenser 2 is connected to the capillary 5 through the drying filter 3, the capillary 5 is connected to the evaporator 4, the outlet of the evaporator 4 is connected to the compressor 1, the refrigerator liner 8 is installed inside the refrigerator shell 9, and a groove is provided on the upper side of the refrigerator liner 8, as shown in FIG. Figure 5 As shown, the outlet of the groove of the refrigerator liner 8 is inclined to serve as a wind guide; Figure 4 As shown, an in-box turbulent fan 11 is installed in the groove. When the refrigerator is running in cooling mode or heating mode, the in-box turbulent fan 11 is turned on to force convection of the air in the box into a turbulent state, thereby accelerating the cooling and heating efficiency; Figure 2 As shown, a defrost heating wire 12 is installed on the upper part of the in-box turbulence fan 11. When the refrigerator is set to the cooling mode, the defrost heating wire 12 will be turned on regularly to prevent the in-box turbulence fan blades from freezing due to the refrigerator temperature being too low.
[0024] like Figure 1 As shown, in order to achieve heating for the refrigerator in this specific embodiment, the following technical solution is specifically adopted: a heating film 13 is installed in the refrigerator inner tank 8, and the heating film 13 is used to heat the refrigerator inner tank 8.
[0025] like Figure 2 As shown, in order to control the compressor in this specific implementation, a compressor driving module 6 is installed on the side wall of the bracket, and the compressor driving module 6 is electrically connected to the compressor 1; the bracket is L-shaped.
[0026] like Figure 3 As shown, in order to facilitate user operation in this specific embodiment, the following technical solutions are specifically adopted: a refrigerator door 14 is installed on the front side of the refrigerator shell 9 through a rotating shaft; a display operation panel 7 is installed on the upper side of the refrigerator door 14, and the display operation panel 7 is used for the user to set the temperature and working mode of the cold and warm boxes.
[0027] The working principle of this specific implementation mode is: when the refrigerator is set to cooling mode, the defrost heating wire 12 will be opened regularly to prevent the fan blades of the turbulence fan 11 in the box from freezing due to the refrigerator temperature being too low; the refrigerator is designed with a rapid cooling / heating mode, at which time the turbulence fan 11 in the box will run at full load to ensure the heat exchange efficiency, and the refrigerator is designed with an energy-saving mode. When the refrigerator reaches the set temperature, the turbulence fan 11 in the box stops running to ensure that the temperature is maintained while reducing energy consumption; the refrigerator is designed with a constant temperature mode, at which time the turbulence fan 11 in the box will run at 20% to 70% of the power to ensure that the temperature of each point in the box is uniform.
[0028] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.

[0029] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
