Description

Technical Field

[0001] This utility model relates to the field of automotive environmental sterilization technology, and in particular to an ultraviolet sterilization device and an automotive air conditioning system for vehicle air conditioning. Background Technology

[0002] Car air conditioning filters can effectively filter out large solid particles such as dust, pollen, and soot from the air entering the car, thus improving the air quality inside the vehicle and enhancing the physical and mental health of passengers.

[0003] However, as the air conditioning filter is used for a longer period of time, its filtration effect will decrease. The tiny particles adsorbed by the air conditioning filter will enter the car through the air conditioning intake duct. Long-term inhalation by passengers can cause skin allergies and respiratory diseases.

[0004] In addition, when the air conditioning system is running, moisture in the air condenses on the surface of the evaporator. Some of this water remains in the evaporator and air conditioning pipes after the air conditioning is turned off. This moisture combines with microorganisms and pollutants in the air, creating a breeding ground for molds, Aspergillus, Penicillium, L. Bacillus, and mites in the damp and dark air conditioning system. These bacteria are carried into the car through the air conditioning system's ducts and cannot be filtered out by the air conditioning filter, directly affecting people's physical and mental health. Utility Model Content

[0005] The purpose of this invention is to provide an ultraviolet sterilization device and an in-vehicle air conditioning system for use in vehicle air conditioning, thereby solving the problem that existing technologies cannot kill bacteria inside vehicles.

[0010] A blocking grille is disposed on the inner and / or outer side of the air inlet and the inner and / or outer side of the air outlet; the blocking grille is used to prevent the ultraviolet light emitted by the LED ultraviolet germicidal lamp from escaping from the sterilization chamber.

[0011] Furthermore, the air inlet and the air outlet are arranged opposite to each other.

[0012] Furthermore, the inner wall of the sterilization chamber and both the inner and outer sides of the barrier grid are coated with ultraviolet light absorbing material.

[0013] Furthermore, the length extension direction of the barrier grille is consistent with the airflow direction.

[0014] The second aspect of this utility model provides a vehicle air conditioning system, including a filter, a blower, an evaporator core, a heater core and a control unit, and also includes the aforementioned ultraviolet sterilization device for vehicle air conditioning.

[0015] Furthermore, the blower is electrically connected to the blower motor, and the control unit is electrically connected to the blower motor.

[0016] Furthermore, the evaporator core is located downstream of the blower, and the evaporator core is used to cool the air flowing through the blower.

[0017] Furthermore, the heater core is located downstream of the evaporator core, and an air mixing control damper is provided between the heater core and the evaporator core. The air mixing control damper is electrically connected to the control unit. The control unit controls the opening of the air mixing control damper to adjust the amount of air delivered to the heater core after passing through the evaporator core, and the amount of air bypassing the heater core after passing through the evaporator core.

[0018] Furthermore, it also includes an internal / external circulation control damper, which is installed at the air inlet of the vehicle air conditioning system and is electrically connected to the control unit; the control unit controls the switching of the position of the internal / external circulation control damper to activate the internal circulation mode / external circulation mode.

[0029] The technical solution of this utility model 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 this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] like Figure 1 The diagram shows a structure of an ultraviolet sterilization device for vehicle air conditioning, which includes a sterilization chamber 1, an LED ultraviolet sterilization lamp 2, and a barrier grille 3.

[0031] Specifically, the sterilization chamber 1 has several air inlets 101 and air outlets 102, and the air inlets 101 and air outlets 102 are arranged opposite to each other, with the opening direction of the air inlets 101 and air outlets 102 consistent with the air flow direction.

[0032] In this embodiment, the sterilization chamber 1 is positioned between the filter 4 and the blower 5 in the vehicle air conditioner. The air inlet 101 of the sterilization chamber 1 is connected to the air outlet of the filter 4, and the air outlet 102 of the sterilization chamber 1 is connected to the air inlet of the blower 5. The blower 5 introduces the airflow filtered by the filter 4 into the sterilization chamber 1 for bacterial sterilization, and then blows the sterilized airflow into the downstream equipment.

[0033] LED ultraviolet germicidal lamps 2 are installed inside the sterilization chamber 1. The number and location of the germicidal lamps can be arranged reasonably according to needs, as long as it is ensured that the ultraviolet light emitted by the ultraviolet germicidal lamps does not overflow from the sterilization chamber 1 and does not cause radiation to passengers or affect human health.

[0034] To prevent ultraviolet light emitted by the LED ultraviolet germicidal lamp 2 from overflowing into the sterilization chamber 1, in this embodiment, a blocking grille 3 is provided at the air inlet 101 and the air outlet 102. The blocking grille 3 encloses the air inlet 101 and the air outlet 102 to prevent the ultraviolet light emitted by the LED ultraviolet germicidal lamp 2 from passing through the air inlet 101 and the air outlet 102 and emitting radiation risks to the external environment. The blocking grille 3 can be located on the inner side (air outlet end) and / or the outer side (air inlet end) of the air inlet 101, and on the inner side (air inlet end) and / or the outer side (air outlet end) of the air outlet 102. The specific arrangement can be reasonably configured according to needs.

[0035] In this embodiment, the length extension direction of the blocking grille 3 is consistent with the airflow direction, and the cross-section of the blocking grille 3 can be circular or square, as long as it can ensure a good blocking effect on ultraviolet light.

[0036] In addition, to further prevent ultraviolet light from escaping from the sterilization chamber 1, in this embodiment, ultraviolet light absorbing materials are coated on the inner wall of the sterilization chamber 1 and on the inner and outer sides of the blocking grid 3. For example, inorganic ultraviolet light absorbing materials such as titanium dioxide, zinc oxide or carbon black can be coated; or organic ultraviolet light absorbing materials such as salicylates or benzophenone can be coated.

[0037] like Figure 2 The diagram shows the structure of a vehicle air conditioning system, which includes a filter 4, a blower 5, an evaporator core 6, a heater core 7, a control unit 8, an air mixing control damper 10, an internal and external circulation control damper 11, and a mode control damper 12.

[0038] Filter 4 is used to filter the airflow entering the vehicle air conditioning system before it is discharged. In this embodiment, an internal / external circulation control damper 11 is installed at the airflow inlet, i.e., the air intake of the vehicle air conditioning system. This damper is electrically connected to the control unit 8. The control unit 8 controls the switching of the internal / external circulation control damper 11, selectively switching the air intake mode of the vehicle air conditioning system between internal and external circulation modes. Regardless of whether it is internal or external circulation mode, the airflow must first be filtered by filter 4 before being sent to downstream equipment.

[0039] The blower 5 provides power for the airflow within the vehicle's air conditioning system. One end of the blower 5 is electrically connected to a blower motor 9, and the aforementioned control unit 8 is also electrically connected to the blower motor 9. The control unit 8 sends control signals to the blower motor 9, which then provides the corresponding driving force to the blower 5.

[0040] After being filtered by filter 4, the airflow is then transported to the aforementioned ultraviolet sterilization device for disinfection and sterilization by the blower 5. After sterilization, the airflow is then transported to the evaporator core 6 downstream of the blower 5. The evaporator core 6 is used to cool the airflow passing through the blower 5, thereby lowering its temperature.

[0041] A heater core 7 is disposed downstream of the evaporator core 6, and an air mixing control damper 10 is disposed between the heater core 7 and the evaporator core 6. This damper is also electrically connected to the control unit 8. In this embodiment, the control unit 8 controls the opening of the air mixing control damper 10 to adjust the airflow rate entering the heater core 7 after passing through the evaporator core 6, and the airflow rate bypassing the heater core 7 after passing through the evaporator core 6 (i.e., the airflow rate that does not enter the heater core 7). In other words, by controlling the opening of the air mixing control damper 10, it is configured to selectively heat the airflow processed by the evaporator core 6.

[0042] In this embodiment, a mode control damper 12 is also provided. The mode control damper 12 is also electrically connected to the aforementioned control unit 8, and the opening degree of the mode control damper 12 is controlled by the control unit 8. The mode control damper 12 includes a defrost mode damper, a face blowing mode damper, and a foot blowing mode damper, which are installed in the vehicle air conditioning system. By controlling the corresponding mode dampers, the defrost mode damper, face blowing mode damper, and foot blowing mode damper can be selectively opened or closed as needed.

[0043] In summary, by installing an ultraviolet sterilization device in the vehicle's air conditioning system, this utility model sterilizes the airflow after it has been filtered and then transports it to downstream equipment. This effectively kills bacteria carried in the air inside the vehicle, greatly improving the environmental quality inside the car and benefiting the physical and mental health of passengers.

[0044] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the protection scope of this utility model.
