Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to an in-vehicle refrigerator / heater. This application also relates to a center console device including such an in-vehicle refrigerator / heater. Background Technology

[0002] Some vehicles are equipped with onboard refrigerators to meet passengers' needs for refrigerating items such as cold drinks.

[0003] Some existing vehicle-mounted air coolers / heaters include a housing defining a cavity, an evaporator, and a fan. The evaporator and fan are housed in a vertical side panel of the housing, and an air outlet is provided on this side panel. The fan drives the evaporator to generate cold air, which is then blown into the cavity through the air outlet in a direction generally perpendicular to the vertical side panel, thereby cooling the cavity. However, this cooling method can lead to uneven temperature distribution within the cavity, resulting in a poor user experience for the vehicle-mounted air cooler / heater. Utility Model Content

[0004] To address the aforementioned technical problems, the first aspect of this application proposes a vehicle-mounted heating and cooling box. The vehicle-mounted heating and cooling box includes a box body, including a box body panel defining a receiving cavity; and a temperature-changing component adapted to generate a working airflow with a preset temperature; wherein, an air inlet channel is provided on the box body panel, the air inlet channel communicating with the temperature-changing component and extending away from the temperature-changing component; a plurality of air outlets communicating with the receiving cavity are provided on the air inlet channel; the working airflow is adapted to flow from the temperature-changing component into the air inlet channel and enter the receiving cavity through the air outlets.

[0005] In one embodiment, the cross-sectional area of ​​the air inlet channel gradually decreases along the direction away from the temperature-changing component.

[0006] In one embodiment, the air inlet channel is located at the top of the cavity along the height direction of the cavity.

[0009] In one embodiment, the air inlet channel includes a groove disposed on the housing plate, one end of the groove being in communication with the temperature-changing component; the groove includes a groove bottom facing the receiving cavity, and a plurality of air outlets are configured on the groove bottom.

[0010] In one embodiment, the groove is formed on the housing plate and has a slot opposite to the bottom of the groove; the air inlet channel also includes a cover plate that extends along the extension direction of the groove and covers the slot.

[0011] In one embodiment, the housing is also configured with a return air duct, which is connected to the housing cavity and the temperature-changing component. The working airflow is adapted to flow from the housing cavity into the return air duct and form a return airflow, which flows through the return air duct to the temperature-changing component.

[0012] In one embodiment, the return air duct is located below the cavity along the height direction of the cavity.

[0013] In one embodiment, a cold storage module is installed in the return air duct.

[0061] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0062] Figure 1A vehicle 1 according to one embodiment of this application is schematically shown. Figure 1 As shown, vehicle 1 includes two front seats 11 and a center console device 2 located between the two front seats 11.

[0063] Figure 2 A central control unit 2 according to one embodiment of this application is schematically shown. (As...) Figure 2 As shown, the center console device 2 includes a vehicle-mounted refrigerator / heater 3. For example, the vehicle-mounted refrigerator / heater 3 is located at the front of the center console device 2 facing the vehicle's main instrument panel 12, and the door 302 of the vehicle-mounted refrigerator / heater 3 is located on the front side of the center console device 2. In this way, the front-seat occupants of the vehicle can easily open the door 302 to take items 303 into the vehicle-mounted refrigerator / heater 3. Figure 3 and Figure 4 The central control unit 2 according to other embodiments of this application is schematically shown. Figure 3 In the center console device 2 shown, the vehicle-mounted refrigerator / heater 3 is located at the front of the center console device 2 facing the main instrument panel 12 of the vehicle. The door 302 of the vehicle-mounted refrigerator / heater 3 is located on the top surface of the center console device 2, and the door 302 is a single door. Figure 4 In the center console device 2 shown, the in-vehicle refrigerator / heater 3 is located at the front of the center console device 2 facing the main instrument panel 12 of the vehicle. The door 302 of the in-vehicle refrigerator / heater 3 is located on the top surface of the center console device 2, and the door 302 is a double door. It should be understood that, depending on the actual situation, the in-vehicle refrigerator / heater can also be installed in other locations in the vehicle (e.g., between the rear seats), and the form of the door can also be determined according to the actual situation. For simplicity, the following text will refer to... Figure 2 The implementation scheme of this application is described using the central control unit 2 and the vehicle-mounted refrigerator / heater box 3 as examples.

[0064] Reference Figure 5 and Figure 6The vehicle-mounted refrigerator / heater 3 includes a housing 31. The housing 31 includes a housing panel 310 defining a receiving cavity 301. The receiving cavity 301 is used to receive items 303. For example, the housing 31 is generally rectangular to match the shape of the front of the center console assembly 2. In this case, the housing panel 310 includes a bottom panel 311, a top panel 312, and a first side panel 313a, a second side panel 313b, and a third side panel 313c connected between the bottom panel 311 and the top panel 312. The third side panel 313c is opposite to the door 302, and the first side panels 313a and 313b are opposite to each other and connected to the third side panel 313c. In one embodiment, each of the top panel, bottom panel, and these side panels includes an outer panel 314, an inner panel 315, and an insulation layer 316 between the outer panel 314 and the inner panel 315. For example, the insulation layer 316 may include a vacuum insulation panel 316a and / or a foam layer 316b. Vacuum insulation panels and foam layers are well known to those skilled in the art and will not be described in detail here. For example, the foam layer may be a polyurethane foam layer.

[0065] In this application, the direction from the first side panel 313a to the second side panel 313b is defined as the width direction W of the vehicle-mounted refrigerator / heater box 3, the direction from the third side panel 313c to the door 302 is defined as the length direction L of the vehicle-mounted refrigerator / heater box 3, and the direction from the bottom plate 311 to the top plate 312 is defined as the height direction H of the vehicle-mounted refrigerator / heater box 3.

[0066] In the center console device 2 of this application, the first side panel 313a and the second side panel 313b of the vehicle-mounted refrigerator / heater 3 are respectively used as part of the two side panels 21 of the center console device 2, and are respectively formed as part of the outer surface of the two side panels 21 of the center console device 2. Taking the first side panel of the vehicle-mounted refrigerator / heater as an example, in some prior art, the vehicle-mounted refrigerator / heater is completely housed in the center console device, and the first side panel of the vehicle-mounted refrigerator / heater and the corresponding side panel of the center console device are spaced apart along the width direction. Compared with this prior art, in the technical solution of this application, the first side panel of the vehicle-mounted refrigerator / heater is used as part of the corresponding side panel of the center console device (that is, the first side panel of the vehicle-mounted refrigerator / heater and the corresponding side panel of the center console device are integrated into one). Thus, given a fixed width at the front of the center console (i.e., the dimension approximately along the width direction W of the vehicle-mounted refrigerator / heater 3), the width of the vehicle-mounted refrigerator / heater 3 in this application is greater than that of prior art vehicle-mounted refrigerators / heaters, resulting in a larger width of the receiving cavity 301. Consequently, the volume of the receiving cavity 301 of the vehicle-mounted refrigerator / heater 3 in this application is also larger, allowing for the placement of more items within the receiving cavity. For example, the volume of the receiving cavity in a prior art vehicle-mounted refrigerator / heater is approximately 8.56L, while the volume of the receiving cavity in the vehicle-mounted refrigerator / heater of this application is approximately 10.95L.

[0067] Reference Figure 6 and Figure 7The vehicle-mounted hot / cold box 3 also includes a temperature-regulating assembly 32, which generates a working airflow with a preset temperature. Depending on the specific situation, the temperature-regulating assembly 32 may include a cooling module 321 and a heating module 322 (e.g., Figure 10 The refrigeration module 321 is used to generate cold air as a working airflow to lower the temperature within the receiving cavity 301 (e.g., to freeze or refrigerate the item 303 within the receiving cavity 301). The heating module 322 is used to generate warm air as a working airflow to raise the temperature within the receiving cavity 301 (e.g., to heat the item 303 within the receiving cavity 301). When using the vehicle-mounted hot / cold box 3, the refrigeration module 321 and the heating module 322 are typically operated selectively (i.e., when the refrigeration module 321 is operating, the heating module 322 is not operating; and vice versa). In one embodiment, the refrigeration module may be an evaporator, and the heating module may be a resistance wire. Of course, depending on the actual situation, the refrigeration module and / or the heating module may also be other forms, which are not limited here.

[0068] For example Figure 6 The cooling module 321 (or temperature-changing assembly 32) is disposed on the third side plate 313c. For example, a mounting cavity 305 is constructed within the third side plate 313c, and the cooling module 321 (or temperature-changing assembly 32) is mounted within the mounting cavity 305. In the case where the temperature-changing assembly 32 simultaneously includes both the cooling module 321 and the heating module 322 (e.g.) Figure 10 As shown, the refrigeration module 321 and the heating module 322 are arranged side by side along the height direction H on the third side panel 313c, which helps to reduce the volume of the vehicle-mounted refrigerator / heater box 3, thereby facilitating the installation of the vehicle-mounted refrigerator / heater box 3 on the center console device 2.

[0069] For simplicity, the technical solution of this application will be described below using the refrigeration module 321 as an example.

[0070] Reference Figure 5 and Figure 7 Both the first side plate 313a and the second side plate 313b are provided with air inlet channels 33 (that is, the first air inlet channel 334a on the first side plate 313a and the second air inlet channel 334a on the second side plate 313b). Figure 7 As shown, both the first air inlet channel 334a and the second air inlet channel 334a are connected to the refrigeration module 321 (or mounting cavity 305) and extend away from the refrigeration module 321. For example, both the first air inlet channel 334a and the second air inlet channel 334a extend generally along the length direction L from the third side plate 313c toward the door 302. Both the first air inlet channel 334a and the second air inlet channel 334a are provided with multiple air outlets 335 that communicate with the receiving cavity 301. These air outlets 335 are spaced apart from each other along the extension direction of the corresponding air inlet channel.

[0071] When using the vehicle-mounted refrigerator / heater box 3, the cold air generated by the refrigeration module 321 flows into the first air inlet channel 334a and the second air inlet channel 334a. As the cold air flows away from the refrigeration module 321 along the first and second air inlet channels 334a, it enters the receiving cavity 301 through these air outlets 335. This ensures that the cold air is blown relatively evenly to all parts of the receiving cavity 301, which helps to rapidly lower the temperature within the receiving cavity 301. Furthermore, regardless of whether the location within the receiving cavity 301 is near or far from the refrigeration module 321, it is exposed to cold air of approximately the same temperature, resulting in good temperature uniformity within the receiving cavity 301 of the vehicle-mounted refrigerator / heater box 3 of this application.

[0072] In one embodiment, the temperature-regulating component 32 also includes a fan 323 (such as...). Figure 6 (As shown). Fan 323 is used to drive the cold air generated by the cooling module 321 into the first air intake channel 334a and the second air intake channel 334a. Also as... Figure 6 As shown, the fan 323 is also mounted on the third side plate 313c (within the mounting cavity 305), thereby reducing the volume of the vehicle-mounted heat and cold box 3.

[0073] For example Figure 5 As shown, the first air inlet channel 334a is positioned near the top edge of the first side plate 313a, and the second air inlet channel 334a is positioned near the top edge of the second side plate 313b (i.e., these air inlet channels are located at the top of the receiving cavity 301 along the height direction H). Thus, when cold air enters the receiving cavity 301 from the air outlet 335, due to its higher density, it gradually moves downwards from the top of the receiving cavity 301 along the general height direction H, simultaneously cooling the receiving cavity 301 from top to bottom. This prevents the temperature at the top of the receiving cavity 301 from being higher than the temperature at the bottom, thereby improving the temperature uniformity within the receiving cavity 301 and also contributing to a rapid temperature reduction within the receiving cavity 301.

[0074] In one embodiment, multiple air inlet channels are provided on the first side panel, and these air inlet channels are arranged side by side along the height direction of the receiving cavity. Multiple air outlets are provided on each air inlet channel. The same applies to the second side panel. Thus, both the first and second side panels have multiple air outlets along the height direction of the receiving cavity. When using the vehicle-mounted refrigerator / heater box, cold air flows into the receiving cavity from multiple locations along the height direction, which further improves the temperature uniformity within the receiving cavity and allows the temperature inside the receiving cavity to drop more quickly. In another embodiment, air inlet channels extending in a tortuous manner along the height direction of the receiving cavity can also be provided on the first and second side panels, and multiple air outlets are provided on multiple channel segments. This also achieves multiple air outlets on both the first and second side panels along the height direction of the receiving cavity. It should be understood that these air inlet channels or multiple channel segments are all arranged close to the top of the receiving cavity along the height direction of the receiving cavity, so that cold air can smoothly move from the top of the receiving cavity downwards, thereby cooling the receiving cavity from top to bottom along the general height direction.

[0075] Depending on the specific circumstances, a third air inlet channel can also be provided on the third side panel (for example, the third air inlet channel can be located at the top edge of the third side panel), and multiple air outlets can also be provided on the third air inlet channel. This helps to further improve the temperature uniformity within the containment cavity, and also helps to reduce the temperature within the containment cavity more quickly.

[0076] The first air inlet channel 334a and the second air inlet channel 334a have the same structure. For simplicity, only the structure of the first air inlet channel 334a will be described below. In one embodiment, the first air inlet channel 334a is configured such that its cross-sectional area gradually decreases along the direction away from the cooling module 321. According to this structure, although the amount of cold air in the first air inlet channel 334a gradually decreases along the direction away from the cooling module 321, the gradually decreasing cross-sectional area of ​​the first air inlet channel 334a ensures that the flow velocity of the cold air in the first air inlet channel 334a remains essentially unchanged or decreases only slightly. In this way, the cold air can flow smoothly into the receiving cavity 301 not only through the air outlet near the cooling module 321, but also through the air outlet away from the cooling module 321. In other words, the cold air can smoothly enter the receiving cavity 301 from each of the air outlets 335 of the first air inlet channel 334a. This also ensures that all locations within the receiving cavity 301 are exposed to cool air of approximately equal temperature, further improving the temperature uniformity within the receiving cavity 301. The specific dimensions of the cross-sectional area of ​​the first and second air inlet channels can be determined based on actual conditions and will not be elaborated here.

[0077] In one embodiment, the size of the air outlet 335 farther from the cooling module 321 is larger than the size of the air outlet 335 closer to the cooling module 321. This ensures that the flow rate of cold air from each air outlet 335 is approximately the same, which also helps to further improve the temperature uniformity within the receiving cavity 301. The specific size of the air outlet 335 can be determined according to actual conditions and will not be elaborated here.

[0078] like Figure 11 As shown, a groove 336 is formed on the outer surface of the first side panel 313a away from the receiving cavity 301. The groove 336 has a first end 336a and a second end 336b opposite to each other. The first end 336a communicates with the mounting cavity 305 (or the refrigeration module 321), and the second end 336b is closed. The groove 336 also has a groove bottom 337 facing the receiving cavity 301 and a slot 338 opposite to the groove bottom 337. An air outlet 335 is formed on the groove bottom 337. The slot 338 is covered by a cover plate 339 extending along the extending direction of the groove 336. Thus, the groove 336 and the cover plate 339 together define a first air inlet channel 334a. According to this structure, the first air inlet channel 334a is part of the first side panel 313a, which simplifies the structure of the vehicle-mounted refrigerator / heater box 3.

[0079] In one embodiment, a separate groove may also be provided. The groove has an open first end and a closed second end. Additionally, the groove has a bottom and a corresponding opening. Multiple air outlets are provided on the bottom. When assembling such a groove onto a first side plate, the opening is fitted onto the first side plate from the inside of the receiving cavity, with the bottom facing the receiving cavity, and the first end of the groove communicating with the mounting cavity (or cooling module). Thus, the groove and the first side plate together define a first air inlet channel. In other embodiments, a separate tubular member may also be provided, with a first end open and a second end closed, and multiple air outlets provided on the sidewall of the tubular member. When assembling such a tubular member onto the inner surface of the first side plate facing the receiving cavity, the first end of the tubular member communicates with the mounting cavity (or cooling module), and the multiple air outlets face the receiving cavity. Thus, the tubular member independently defines a first air inlet channel.

[0080] Reference Figure 6 and Figure 9 The housing 31 also includes a return air duct 34. For example, along the height direction H of the receiving cavity 301, the return air duct 34 is located below the receiving cavity 301. Furthermore, the return air duct 34 communicates with the receiving cavity 301 and the mounting cavity 305 (or the cooling module 321). Thus, the air inlet duct 33, the receiving cavity 301, the return air duct 34, and the mounting cavity 305 together form a circulating airflow channel. When using the vehicle-mounted refrigerator / heater box 3, driven by the fan 323, cold air enters the air inlet duct 33 from the mounting cavity 305 and enters the receiving cavity 301 through the air outlet 335 (e.g., Figure 7 As shown in the airflow direction 304), the denser cold air flows relatively quickly downwards along the height direction H within the receiving cavity 301. The cold air then flows smoothly downwards into the return air channel 34 (as shown in the image). Figure 8 and Figure 9 After the airflow direction (as shown in 304) is oriented, a return airflow is formed in the return air channel 34. Under the suction of the fan 323, the return airflow smoothly returns to the mounting cavity 305 (as shown in 304). Figure 10 The airflow direction (as shown in 304) is further cooled by the cooling module 321 to form a working airflow (i.e., cold air). In this way, the airflow in the vehicle-mounted heating and cooling box 3 generally circulates up and down along the height direction H, which realizes the rapid reduction of the temperature in the receiving cavity 301 and the relatively uniform temperature in the receiving cavity 301.

[0081] For example Figure 9 As shown, a cold storage module 343 is provided within the return air duct 34. The temperature of the recirculating airflow within the return air duct 34 remains low, thus cooling the cold storage module 343 (i.e., the cold storage module 343 stores cold energy). When the vehicle-mounted cooler / heater 3 is not in operation (e.g., when the vehicle-mounted cooler / heater 3 is powered off), the cold storage module 343 provides cooling to the items 303 within the containment cavity 301. This is beneficial for electric vehicles, as powering off the vehicle-mounted cooler / heater helps extend the vehicle's driving range. Furthermore, when the vehicle-mounted cooler / heater 3 is in use, the operating airflow first lowers the temperature within the containment cavity 301, and then enters the return air duct 34 to form a recirculating airflow that cools the cold storage module 343. Throughout the entire airflow cycle, the cold storage module 343 does not compete with the containment cavity 301 for cold energy, which helps to rapidly lower the temperature within the containment cavity 301. Cold storage modules are well known to those skilled in the art and will not be described in detail here.

[0082] In one embodiment, such as Figure 9 As shown, the return air duct 34 and the receiving cavity 301 are separated by a partition plate 341. The partition plate 341 is generally parallel to the bottom plate 311, and multiple connecting holes 342 are provided on the partition plate 341 to enable communication between the return air duct 34 and the receiving cavity 301.

[0083] For example Figure 9 As shown, a drawer 306 is provided within the receiving cavity 301 for holding items 303. Multiple ventilation holes 307 are located on the side wall of the drawer 306. The ventilation holes 307 connect the receiving cavity 301 and the drawer 306. In this way, working airflow can enter the drawer 306 through the ventilation holes 307 to cool the items 303 inside the drawer 306. Working airflow within the drawer 306 also flows out of the drawer 306 through the ventilation holes 307, for example, flowing towards the return air channel 34, making airflow circulation smoother. In one embodiment, the ventilation holes are configured as elongated shapes extending along the height direction H (e.g., Figure 9 (As shown). Of course, depending on the actual situation, the ventilation holes can also be other shapes. For example, the ventilation holes are generally circular, and multiple such ventilation holes are provided along the height direction H on the side wall of the drawer.

[0084] To facilitate the reciprocating sliding of drawer 306 along its length L, guide rails 344 (such as...) are provided on the divider 341. Figure 5 (As shown). A sliding foot 308 matching the guide rail 344 is provided on the drawer 306. After the sliding foot 308 is slidably engaged with the guide rail 344, the drawer 306 can smoothly slide back and forth along the length direction L, and the drawer 306 is not easy to wobble along the width direction W and the height direction H, which improves the quality of the vehicle refrigerator / warmer 3.

[0085] For example Figure 5 As shown, after the guide rail 344 is installed on the partition 341, the return air channel 34 forms an irregularly shaped space. Usually, such irregularly shaped spaces are difficult to use, resulting in a non-compact structure and large volume of the vehicle-mounted refrigerator / heater box. In this application, the cold storage module 343 is set in this irregularly shaped space (or return air channel 34), which improves the structural compactness of the vehicle-mounted refrigerator / heater box 3. This helps to reduce the volume of the vehicle-mounted refrigerator / heater box 3 while keeping the volume of the receiving cavity 301 unchanged, thereby facilitating the installation of the vehicle-mounted refrigerator / heater box 3 on the center console device 2.
