Detailed Implementation
[0020] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0021] This invention provides an in-vehicle device and a vehicle. Several embodiments are given below to describe the in-vehicle device and vehicle provided by this invention in detail.
[0022] The vehicle-mounted equipment provided in this embodiment, such as Figure 1 As shown, it includes an oxygen generating component and a refrigerator component; the oxygen generating component includes an oxygen generating mechanism and a nitrogen storage tank 9; the nitrogen outlet of the oxygen generating mechanism is connected to the nitrogen storage tank 9, and the nitrogen discharged from the nitrogen outlet can flow into the nitrogen storage tank 9; the refrigerator component includes a heat exchange area, the nitrogen storage tank 9 is connected to the heat exchange area, and the nitrogen discharged from the nitrogen storage tank 9 can flow into the heat exchange area.
[0023] The oxygen generator is an on-board unit. While producing oxygen, it also generates a large amount of high-purity nitrogen. Nitrogen is chemically stable and does not participate in the oxidation of food components, nor does it support microbial growth. Aerobic microorganisms (bacteria, molds) experience metabolic inhibition and a reduction in reproduction rate of over 90% in low-oxygen environments.
[0024] Nitrogen gas discharged from nitrogen storage tank 9 flows into the heat exchange area. After being heated to a suitable temperature in the heat exchange area, the nitrogen gas flows into the refrigerator compartment 12 of the refrigerator assembly to preserve food. Using nitrogen to preserve food can prevent the photo-oxidation of fats caused by direct irradiation of dairy products by UV lamps, prevent the refrigerator assembly from producing odors, and eliminate the need for regular cleaning of UV lamp tubes with alcohol, making it highly convenient to use.
[0025] Furthermore, in the prior art, the nitrogen emitted by the vehicle-mounted oxygen generator is wasted by direct discharge. The vehicle-mounted device provided in this embodiment can use the nitrogen emitted by the oxygen generator to preserve food, thereby improving the utilization rate of the nitrogen emitted by the oxygen generator.
[0026] Furthermore, the oxygen generating mechanism includes an air compressor 2, a cooler 16, and a molecular sieve 3 connected in sequence; the molecular sieve 3 is provided with an oxygen outlet and a nitrogen outlet.
[0027] Air compressor 2 is connected to cooler 16 via high-pressure exhaust pipe 17, and cooler 16 is connected to molecular sieve 3 via molecular sieve inlet pipe 18. Oxygen outlet of molecular sieve 3 is connected to oxygen storage tank 4 via molecular sieve outlet pipe 19. Oxygen storage tank 4 is connected to oxygen supply terminal via oxygen supply channel 20.
[0028] Outdoor air enters the air compressor 2 and is compressed and pressurized into high-temperature, high-pressure air. The high-temperature, high-pressure air then enters the air cooler 16 for cooling, becoming low-temperature, high-pressure air. After entering the molecular sieve 3, the oxygen discharged from the oxygen outlet enters the oxygen storage tank 4 through the adsorption effect of the molecular sieve 3. The oxygen in the oxygen storage tank 4 enters the oxygen supply terminal (there can be multiple oxygen supply terminals, including the first oxygen supply terminal 5, the second oxygen supply terminal 6, the third oxygen supply terminal 7, and the fourth oxygen supply terminal 8 in this embodiment) through the oxygen supply channel 20, providing high-concentration oxygen to vehicle users. The nitrogen discharged from the nitrogen outlet is sent to the nitrogen storage tank 9, and the nitrogen in the nitrogen storage tank 9 enters the heat exchange area.
[0029] Furthermore, the oxygen generating unit also includes a filter 1, which is connected to the inlet of the air compressor 2.
[0030] Filter 1 is fixed at the inlet of air compressor 2. Outdoor air is filtered by filter 1 and then enters air compressor 2 for compression. Filter 1 can filter the air and prevent impurities from entering air compressor 2.
[0031] The nitrogen outlet and the nitrogen storage tank 9 can be connected by a pump, and the nitrogen discharged from the nitrogen outlet can be pumped into the nitrogen storage tank 9.
[0032] In this embodiment, the nitrogen outlet and the nitrogen storage tank 9 are connected via the air compressor 2.
[0033] The nitrogen outlet of molecular sieve 3 is connected to nitrogen storage tank 9 through nitrogen venting channel 21 of molecular sieve 3.
[0034] Among them, the air compressor 2 can be a two-cylinder air compressor 2, or a four-cylinder air compressor 2, or any other multi-cylinder air compressor 2.
[0035] For example, the air compressor 2 is a dual-cylinder air compressor 2. The inlet of one cylinder of the air compressor 2 is connected to the outside air, and the outlet of the other cylinder is connected to the cooler 16. The other cylinder of the air compressor 2 is connected to the nitrogen outlet and the nitrogen storage tank 9. Nitrogen can be discharged from the nitrogen outlet to the nitrogen storage tank 9 by the vacuum action of the other cylinder.
[0036] By using an air compressor 2, both air compression and nitrogen discharge into the nitrogen storage tank 9 can be achieved, thereby improving the functionality of the air compressor 2 and increasing the integration of the vehicle equipment.
[0037] Furthermore, an evaporator 10 is provided in the heat exchange area, and a cooler 16 is provided in the heat exchange area.
[0038] Outdoor air enters air compressor 2 through filter 1, and is pressurized by air compressor 2 into high-temperature and high-pressure air. The high-temperature and high-pressure air enters cooler 16, which is located in the heat exchange area. The high-temperature and high-pressure air in cooler 16 exchanges heat with the low-temperature nitrogen in the heat exchange area and is cooled into low-temperature and high-pressure air.
[0039] Using low-temperature nitrogen gas in the heat exchange zone to cool the high-temperature, high-pressure air in the cooler 16 can improve energy utilization.
[0040] Furthermore, the refrigerator assembly also includes an insulation layer 13 and a refrigerator compartment 12; the insulation layer 13 surrounds the refrigerator compartment 12 and the heat exchange area.
[0041] The heat exchange area is located on the back side of the back panel of the refrigerator 12, and the insulation layer 13 is arranged around the outside of the refrigerator 12 and the heat exchange area to insulate the heat exchange area and the refrigerator 12.
[0042] Furthermore, the heat exchange area is provided with an air inlet 14 and a return air inlet 15 at intervals; the air inlet 14 and the return air inlet 15 are respectively connected to the refrigerator 12 and the heat exchange area.
[0043] A fan 11 is also installed in the heat exchange area.
[0044] In summer, the refrigerator components activate a cooling cycle. The refrigerator components include a cooling system comprising a compressor, condenser, expansion valve, and evaporator 10. Low-temperature, low-pressure refrigerant from the expansion valve enters the evaporator 10 via the evaporator inlet pipe 23, transferring its cooling capacity to nitrogen in the heat exchange area. The nitrogen cools down, becoming low-temperature nitrogen. This low-temperature nitrogen enters the refrigerator compartment 12 via the fan 11 and air inlet 14, and then returns to the heat exchange area via the return air inlet 15, completing a full cycle and achieving the low-temperature nitrogen preservation function. The evaporator 10 also has an evaporator exhaust pipe 24.
[0045] When the refrigerator unit turns on the heating mode in winter, the high-temperature and high-pressure air compressed by the air compressor 2 enters the cooler 16. The fan 11 in the heat exchange area blows the nitrogen in the refrigerator compartment 12 into the heat exchange area from the return air vent 15. After passing through the cooler 16, the nitrogen absorbs the heat of the high-temperature and high-pressure air. The heated nitrogen then enters the refrigerator compartment 12 through the air inlet 14, thus realizing a complete heating cycle.
[0046] Furthermore, a nitrogen concentration sensor is installed inside the refrigerator 12; when the nitrogen concentration inside the refrigerator 12 is lower than a preset value, the nitrogen storage device 9 supplies nitrogen to the heat exchange area.
[0047] The nitrogen storage tank 9 is connected to the heat exchange area through the nitrogen storage tank exhaust pipe 22. The nitrogen storage tank exhaust pipe 22 is equipped with a solenoid valve. The nitrogen concentration sensor is connected to the controller. The nitrogen concentration sensor detects the nitrogen concentration in the refrigerator 12. When the nitrogen concentration in the refrigerator 12 decreases and falls below a preset value, the controller controls the solenoid valve to open. The nitrogen storage tank 9 delivers high-concentration nitrogen to the heat exchange area until the nitrogen concentration in the refrigerator 12 reaches the preset value. Then, the controller controls the solenoid valve to close, thus intelligently ensuring the nitrogen concentration in the refrigerator 12.
[0048] Furthermore, the refrigerator assembly also includes a condenser; temperature sensors are respectively provided at the air inlet 14, the air return 15, and the air inlet of the condenser.
[0049] Temperature sensors are installed at the air inlet 14, air return 15, and air inlet of the condenser. The temperature sensors are connected to the controller, the air inlet damper at the front of the cooler 16, the fan 11, and the compressor of the refrigeration system of the refrigerator assembly. The controller adjusts the opening of the air inlet damper at the front of the cooler 16, the speed of the fan 11, and the speed of the compressor of the refrigeration system of the refrigerator assembly by real-time temperature detection by multiple temperature sensors, so as to maintain a suitable temperature inside the refrigerator 12 and maintain a suitable temperature for the air entering the molecular sieve 3.
[0050] The vehicle-mounted device provided in this embodiment can supply nitrogen to the refrigerator components. The nitrogen supplied to the refrigerator compartment 12 is of high quality and can achieve low-temperature nitrogen preservation. A dryer can be installed between the nitrogen storage tank 9 and the heat exchange area to keep the nitrogen dry, thereby preventing water accumulation and ice formation inside the refrigerator compartment 12.
[0051] The vehicle provided in this embodiment includes the vehicle-mounted equipment provided in this embodiment. Nitrogen gas discharged from the nitrogen storage tank 9 flows into the heat exchange area. After being heated to a suitable temperature in the heat exchange area, the nitrogen gas flows into the refrigerator compartment 12 of the refrigerator assembly to preserve food. Using nitrogen to preserve food can prevent photo-oxidation of fats caused by direct UV light irradiation of dairy products, prevent odors from developing in the refrigerator assembly, and eliminate the need for periodic cleaning of the UV lamp tubes with alcohol, making it highly convenient to use.
[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
