the first embodiment,
As shown in fig. 3 to 6, the embodiment of the present invention provides an air conditioner sterilizer for a vehicle, which includes a housing assembly, a sterilizing assembly and an air conditioning assembly 9.
The housing assembly comprises a box 4 and a partition 7. The box body 4 is provided with a containing cavity, and an air inlet 8 and an air outlet 5 which are communicated with the containing cavity. The baffle 7 is arranged on the box body 4 to divide the containing cavity into a disinfection cavity communicated with the air inlet 8 and an air-conditioning cavity communicated with the air outlet 5. The partition plate 7 is provided with a gas passing passage 6 for communicating the sterilization chamber and the air conditioning chamber, and a first blocking part 12 extending to the inside of the sterilization chamber. The first blocking portion 12 is used to divide the sterilization chamber into an air inlet passage 11 communicated with the air inlet 8 and a sterilization passage 13 communicated with the air inlet passage 11 and the air passing passage 6. The first blocking portion 12 is configured to block light from propagating from the disinfection channel 13 to the air inlet 8. The sterilizing assembly includes a uv sterilizing lamp 10 disposed in a sterilizing tunnel 13. The air conditioning assembly 9 is configured in the air conditioning cavity and used for extracting air from the air passage 6 and discharging the air from the air outlet.
Specifically, the partition plate 7 is disposed in the middle of the chamber to divide the chamber into a sterilization chamber and an air conditioning chamber. And, a first blocking part 12 is provided at a side of the partition 7 facing the sterilization chamber. The first blocking part 12 is strip-shaped, extends from the partition board 7 towards the side wall of the box body 4, and divides the disinfection cavity into a lower air inlet channel 11 and an upper disinfection channel 13 which are communicated with each other. The ultraviolet disinfection lamp 10 and the air inlet 8 are respectively arranged at two sides of the first blocking part 12, so that light rays emitted by the ultraviolet disinfection lamp 10 cannot penetrate through the air inlet 8 to irradiate the outside of the air conditioner killing device 2. And, air inlet channel 11 and disinfection passageway 13 that set up from top to bottom, control volume that can be fine to under the prerequisite that does not change current air conditioner's appearance, increase the disinfection function. So that the medical cabin can be disinfected by ultraviolet rays under the condition that people exist in the medical cabin, and the air in the medical cabin is kept clean.
In another embodiment, the first blocking portion 12 extends from one side end portion to the other side end portion of the partition 7. That is, the sterilizing passage 13 communicates with the air inlet passage 11 at one end of the partition 7, and the other end is sealed. The air passage 6 is provided above the sealed end of the first blocking portion 12. So that the air flow flows into the sterilizing channel 13 from one side of the first blocking part 12, flows to the other side of the sterilizing channel 13 and then enters the air passing channel 6. In the case where the second blocking portion 14 is not provided, it is possible to ensure that the air flow passes in front of the ultraviolet sterilizing lamp 10, thereby ensuring the sterilizing effect.
It can be understood that the ultraviolet disinfection lamp 10 can effectively inactivate viruses and bacteria, the inactivation rate is as high as 99.9%, and the defect of oxidation of vehicle-mounted aluminum equipment in a cabin by ozone is avoided. The embodiment divides the air conditioning system of the medical cabin into an air conditioning cavity and a disinfection cavity by rearranging and designing the components of the air conditioning system of the medical cabin. The air-conditioning cavity is internally provided with a heater, an air-steaming conditioner, a condensed water collecting pipe, a high-low pressure passing pipe, a cable and a heat insulation bracket. An ultraviolet disinfection lamp 10 is arranged in the disinfection chamber. The box body 4 adopts an air duct box made of lightproof Wolk composite high-density material.
The ultraviolet disinfection lamp 10 is arranged in the box body 4, and the appearance of the medical cabin of the original ambulance is maintained. The Wolk composite high-density material has smooth and flat surface, corrosion resistance, high hardness, fire resistance, flame retardance, reliable insulating property, no deformation, easy cleaning and good antibacterial effect. The air duct box adopts seamless design, and effectively meets the air purification requirement in the transportation process of the ambulance.
As shown in fig. 6, in the present embodiment, the air inlet 8, the first blocking portion 12, the ultraviolet sterilizing lamp 10 and the air passing channel 6 are sequentially disposed in the middle of the partition 7 from bottom to top. That is, there is a height difference between the ultraviolet ray sterilizing lamp 10 and the air passing channel 6, and the air is easy to flow directly to the air passing channel 6 without passing through the front of the ultraviolet ray sterilizing lamp 10. The partition 7 is therefore also provided with a second stop 14 extending towards the inside of the chamber. The second blocking portion 14 is disposed between the air passage 6 and the ultraviolet sterilizing lamp 10 to guide the air flow passing in front of the ultraviolet sterilizing lamp 10.
Specifically, the second blocking portion 14 is disposed between the air passage 6 and the ultraviolet ray sterilizing lamp 10, and a gap is provided at a position facing the middle portion of the ultraviolet ray sterilizing lamp 10, through which the air in front of the ultraviolet ray sterilizing lamp 10 enters the air passage 6. Thereby ensuring that the air flow entering the air passage 6 passes through the front of the ultraviolet disinfection lamp 10 to ensure the disinfection effect.
As shown in fig. 6, in the present embodiment, the partition 7 is provided with one first stopper 12 and two second stoppers 14. The first stopper 12 extends from the middle of the partition 7 to both sides. And two second stoppers 14 extending from both sides of the partition 7 toward the middle. Both sides of the air inlet passage 11 communicate with the sterilizing passage 13. And, the air intake 8 is provided in the middle of the air intake passage 11. The air passage 6 is arranged in the middle of the disinfection passage 13.
Specifically, the first stoppers 12 extend from the middle of the partition 7 to both sides, and do not extend to the end portions. So that the sterilizing channel 13 and the air inlet channel 11 communicate at both ends of the first barrier 12. The two second blocking parts 14 extend from the two ends of the partition 7 to the middle respectively, the middle is not closed, and a gap for air flow to flow from the middle of the disinfection channel 13 to the air passing channel 6 is reserved. As shown in fig. 6, the air flow flows into the intake passage 11 from the middle of the intake passage 11, and then flows to both sides. Flows into the disinfection channel 13 through both sides of the first barrier and then flows into the gas passage 6 from both sides of the disinfection channel 13.
Allowing airflow to flow into the disinfection passage 13 from both sides of the air intake passage 11. So that the cross-sectional area of flow of the gas stream is twice as large as the cross-sectional area of the single-sided entry. The air input is greatly improved, so that the air conditioning assembly 9 can filter enough air, and the cleanness of the air in the vehicle is ensured.
In this embodiment, the housing 4 is made of a light-impermeable Wolk composite high-density material. The disinfection cavity is divided into 3 layers of air inlet cavities for seamless design. After passing through the air inlet 8 and the air inlet channel 11, the gas flows through the disinfection channel 13, is completely disinfected by the built-in ultraviolet disinfection lamp 10, and clean gas is discharged from the air outlet 5 through the fan. The medical cabin has a compact structure, can ensure the health and safety of personnel in the cabin, can solve the problem of limitation of the arrangement space in the cabin, and increases the space of the medical cabin as much as possible. The air conditioning system in the air duct box can perform air temperature and humidity adjusting functions such as refrigeration, heating, defrosting and the like, not only can provide comfortable environment for passengers, but also can provide a sterilization environment with the ultraviolet disinfection lamp 10 suitable for temperature and humidity.
It can be understood that the present embodiment employs the ultraviolet disinfection lamp 10 disposed in the box body 4 for disinfection, which can prevent the air conditioning system of the medical cabin from being polluted by harmful gas during or after the transportation of the ambulance. The scheme ensures that passengers are not injured by the ultraviolet disinfection lamp 10 and the ozone machine during working, avoids electrostatic field interference of plasma air on nearby electronic equipment, and meets the air circulation sterilizing requirement.
As shown in fig. 5 and 6, the partition 7 is provided with a through hole. The ultraviolet sterilizing lamp 10 passes through the through hole from the air-conditioning chamber and extends into the sterilizing passage 13 to irradiate the sterilizing passage 13. Specifically, the sterilizing lamp is extended into the sterilizing chamber through the through hole from the side of the air-conditioning chamber so as to reduce the protrusion of the ultraviolet sterilizing lamp 10 in the sterilizing passage 13.
