Description

Technical Field

[0001] This utility model relates to the field of air treatment technology, specifically providing an air conditioner with ultraviolet sterilization function. Background Technology

[0002] Air conditioners typically regulate indoor temperature by exchanging heat between indoor air and an indoor heat exchanger. During operation, to save energy and quickly reach the preset temperature, doors and windows are usually closed. Over time, this leads to an increase in bacteria and particulate matter concentrations in the indoor air. Bacteria, fungi, and other microorganisms can also proliferate inside the air conditioner and enter the room with the airflow, reducing indoor air quality. Therefore, air conditioners are often equipped with sterilization modules to disinfect the air passing through them, thereby improving indoor air quality.

[0003] Currently, the most commonly used sterilization modules are ultraviolet (UV) sterilization devices, which sterilize and disinfect objects by irradiating them with ultraviolet light emitted by the device. However, they can only sterilize and disinfect the air and surfaces within their irradiation range, and the irradiation area of ​​UV sterilization devices is usually quite limited, resulting in poor sterilization effectiveness.

[0004] Accordingly, a new technical solution is needed in this field to solve the above problems. Utility Model Content

[0005] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problems of limited irradiation area and poor sterilization effect of ultraviolet sterilization devices in the prior art.

[0006] This utility model provides an air conditioner with ultraviolet sterilization function. The air conditioner is equipped with an ultraviolet sterilization device, which includes a mounting bracket and an ultraviolet part disposed on the mounting bracket. The ultraviolet sterilization device is mounted to the air conditioner through the mounting bracket. The ultraviolet part includes a first ultraviolet component and a second ultraviolet component. When the first ultraviolet component is powered on, the ultraviolet rays emitted are directed along a first direction, and when the second ultraviolet component is powered on, the ultraviolet rays emitted are directed along a second direction. There is an angle between the first direction and the second direction.

[0007] In the preferred embodiment of the air conditioner described above, the angle between the first direction and the second direction is in the range of 60° to 120°.

[0008] In the preferred embodiment of the air conditioner described above, the first direction and the second direction are perpendicular to each other.

[0009] In the preferred embodiment of the above-mentioned air conditioner, the air conditioner includes an indoor unit, the indoor unit includes a casing, the casing has an air inlet, the ultraviolet sterilization device is disposed near the air inlet, and one of the first direction and the second direction extends along the length direction of the air inlet.

[0010] In the preferred embodiment of the above-mentioned air conditioner, a heat exchanger is provided inside the casing, the first direction extends along the length of the air inlet, and the second direction is the direction toward the heat exchanger.

[0011] In the preferred embodiment of the above-mentioned air conditioner, a mounting cavity is formed on the mounting bracket, and the first ultraviolet component and the second ultraviolet component are disposed in the mounting cavity. The mounting cavity is provided with a first through hole and a second through hole at positions corresponding to the first ultraviolet component and the second ultraviolet component, respectively, so as to allow the ultraviolet rays emitted by the first ultraviolet component and the second ultraviolet component to irradiate outward along the first direction and the second direction, respectively.

[0012] In the preferred embodiment of the above-mentioned air conditioner, the mounting bracket includes a base and a cover. A first mounting structure is provided on the base. The mounting cavity is formed by the cover, the first mounting structure, and the base. A first through hole is provided in the first mounting structure, and a second through hole is provided in the position where the base is located inside the mounting cavity.

[0013] In the preferred embodiment of the aforementioned air conditioner, the first ultraviolet component includes at least one LED; and / or

[0014] The second ultraviolet component is a lamp tube.

[0015] In the preferred embodiment of the air conditioner described above, the ultraviolet sterilization device further includes a power supply module, which is disposed on the mounting bracket and is used to supply power to the first ultraviolet component and the second ultraviolet component.

[0016] In the preferred embodiment of the above-mentioned air conditioner, the mounting cavity is provided with a first wire passage hole and a second wire passage hole, so that the electrical wires electrically connected to the first ultraviolet component and the second ultraviolet component can pass through the first wire passage hole and the second wire passage hole respectively and then be electrically connected to the power supply module.

[0017] In this invention, an air conditioner is equipped with an ultraviolet (UV) sterilization device. This device includes a mounting bracket and an ultraviolet (UV) section disposed on the bracket. The UV sterilization device is mounted to the air conditioner via the mounting bracket. The UV section includes a first UV component and a second UV component. When the first and second UV components are energized, the emitted UV rays irradiate along a first direction and a second direction, respectively, with an angle between the first and second directions. By having the first and second UV components irradiate the two directions with an angle, the irradiation area of ​​the UV rays is increased, significantly improving the sterilization effect.

An ultraviolet sterilization device is positioned near the air inlet, extending along the length of the air inlet in one of a first direction or a second direction. This allows for complete coverage of the air inlet area, sterilizing and disinfecting all air flowing through the area, thereby better sterilizing and disinfecting the air in the indoor space and achieving a better sterilization effect.

[0027] The preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. It should be noted that although this embodiment uses a negative ion generator installed on a wall-mounted air conditioner as an example, the negative ion generator can obviously also be installed on a cabinet air conditioner, central air conditioner, ducted air conditioner, or other types of air conditioners, or on an air purifier, sterilizer, or other types of air handling equipment.

[0028] It should be noted that in the description of this utility model, terms such as "inner," "outer," "left," and "right," indicating directional or positional relationships, are based on the directional or positional relationships shown in the accompanying drawings. These are merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, it should be noted that in the description of this invention, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] Furthermore, it should be noted that, in the description of this application, unless otherwise expressly specified and limited, the terms "connected" and "connected" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0030] Currently, the ultraviolet (UV) sterilization devices installed on air conditioners have a limited irradiation area, resulting in poor sterilization performance. Therefore, the UV sterilization device of this application features an angle between the irradiation directions of the UV rays emitted by the first and second UV components when energized, effectively increasing the UV irradiation area and covering the entire interior of the air conditioner, thus significantly improving the sterilization effect.

[0031] The following is combined Figures 1 to 4 This paper describes possible implementation methods of the air conditioner with ultraviolet sterilization function according to the present invention.

[0032] like Figures 1 to 4 As shown, the wall-mounted air conditioner includes an indoor unit, which includes a casing 1, a heat exchanger 3, and an indoor fan installed inside the casing 1. The casing 1 has an air inlet 11 and an air outlet (not shown). Under the action of the indoor fan, the air in the indoor space enters the casing 1 through the air inlet 11, exchanges heat with the heat exchanger 3, and then returns to the indoor space through the air outlet, thereby achieving the purpose of adjusting the temperature of the indoor space. The air conditioner of this application is equipped with an ultraviolet sterilization device 2 at the air inlet 11. The ultraviolet sterilization device 2 includes a mounting bracket 21 and an ultraviolet part 22. The ultraviolet part 22 is installed on the mounting bracket 21 and positioned near the right end of the air inlet 11. In this way, the ultraviolet rays emitted by the ultraviolet part 22 can form an irradiation area near the air inlet 11, and sterilize the air flowing through the irradiation area. The ultraviolet (UV) unit 22 includes a first UV component 221 and a second UV component 222. When the UV sterilization device is powered on, the UV rays emitted by the first UV component 221 irradiate along a first direction, and the UV rays emitted by the second UV component 222 irradiate along a second direction, with an angle between the first and second directions. In this way, by irradiating the entire interior of the casing 1 with the UV rays emitted by the first UV component 221 and the second UV component 222 along two directions with an angle, the UV rays emitted by the UV sterilization device can cover the entire interior of the casing 1, effectively increasing the irradiation area and greatly improving the sterilization effect.

[0033] It should be noted that the ultraviolet sterilization device 2 can also be located at the left end near the air inlet 11, or at other locations within the air duct.

[0034] In one possible implementation, the angle between the first direction and the second direction ranges from 60° to 120°. For example, the angle between the two directions can be 60°, 75°, 90°, 100°, 120°, etc. Within this angle range, more area inside the housing 1 can be covered as much as possible, and a larger area can be irradiated, thereby achieving a better sterilization effect.

[0035] like Figure 1As shown, the first direction extends along the length of the air inlet 11, and the second direction is towards the heat exchanger 3. The first and second directions are perpendicular to each other. That is, the ultraviolet rays emitted by the first ultraviolet component 221 irradiate from right to left along the length of the air inlet 11 to sterilize the air entering the casing 1 through the air inlet 11. The ultraviolet rays emitted by the second ultraviolet component 222 irradiate towards the interior of the casing 1 and the heat exchanger 3 to sterilize the surface of the heat exchanger 3. By making the first and second directions perpendicular to each other, comprehensive coverage of all areas inside the casing 1 is achieved from both horizontal and perpendicular directions. This sterilizes not only the air flowing through the casing 1 but also the surface of the heat exchanger 3 and the indoor fan, frame, and drip tray within its irradiation area, resulting in a better sterilization effect and improved indoor air quality.

[0036] It should be noted that, alternatively, the second direction can extend along the length of the air inlet 11, while the first direction can face the heat exchanger 3. When the first direction extends along the length of the air inlet 11, the second direction can also face the filter, the inner wall of the housing 1, or other possible components or locations within the housing 1. Obviously, the first and second directions may not be perpendicular to each other; that is, the angle between the two directions is not 90°, but rather 75°, 60°, or other smaller angles, or 100°, 120°, or other larger angles. Without departing from the basic principles of this application, those skilled in the art can flexibly choose the extension directions of the first and second directions according to the specific application scenario, as long as it increases the ultraviolet irradiation area and improves the sterilization effect.

[0037] It should be noted that the length of the air inlet 11 is approximately... Figure 1 The horizontal direction in the middle, towards heat exchanger 3, is approximately... Figure 1 The direction perpendicular to the paper.

[0038] like Figures 2 to 4 As shown and in accordance with Figure 2As shown, the mounting bracket 21 includes a base 211 and a cover 212. The base 211 is generally a plate-like structure, and the cover 212 is generally an inverted dome-like structure. A first mounting structure 213 is provided near the left end of the base 211. This first mounting structure 213 is generally a first rectangular mounting plate 2131, which extends vertically from the upper surface of the base 211. A mating portion 2132 is formed at the end of the first rectangular mounting plate 2131 away from the base 211. This mating portion 2132 is formed by inwardly recessing from the outer wall of the first rectangular mounting plate 2131 and is adapted to fit with the cover 212. When the cover 212 is placed on the first mounting structure 213, the lower end of the cover 212 fits with the mating portion 2132, and the outer wall of the cover 212 is flush with the outer wall of the first rectangular mounting plate 2131. Furthermore, when the cover 212 is in place, the cover 212, the first mounting structure 213, and the base 211 form a relatively closed mounting cavity. The first ultraviolet component 221 and the second ultraviolet component 222 are placed inside the mounting cavity, which can isolate them from the external environment and prevent electrical components from getting damp or even being damaged due to severe dampness.

[0039] Continue to refer to Figures 2 to 4 And in accordance with Figure 2 As shown, the first ultraviolet component 221 includes a lamp plate 2211 and two lamp beads 2212 disposed on the lamp plate 2211. For example, the lamp beads 2212 are LED lamp beads, mercury lamps, or xenon lamps. A limiting structure is provided inside the mounting cavity near the first sidewall 21311 of the first rectangular mounting plate 2131. This limiting structure consists of two pairs of opposing limiting plates, and the lamp plate 2211 is fitted into this limiting structure. Two first through holes 214 are provided on the first sidewall 21311 of the first rectangular mounting plate 2131 at positions corresponding to the two lamp beads 2212. This first sidewall 21311 is near the left end of the base 211 and, when installed, is located at the foremost end of the ultraviolet sterilization device 2. The first through holes 214 are generally rectangular. The outer wall of the first sidewall 21311 has inclined surfaces corresponding to each first through hole 214. The distance between these two inclined surfaces gradually increases from the inside out, forming a generally trumpet-shaped structure. When installed, the first ultraviolet component 221 is located at the front end of the ultraviolet sterilization device 2, and the ultraviolet rays emitted by it can pass through the first through hole 214 and extend along the first direction to irradiate the air inlet 11.

[0040] A second rectangular mounting plate 216 is disposed within the mounting cavity. This second rectangular mounting plate 216 is smaller than the first rectangular mounting plate 2131 and is located near the second sidewall 21312 of the first rectangular mounting plate 2131. The second sidewall 21312 is positioned opposite the first sidewall 21311. A roughly rectangular second through-hole 215 is provided within the second rectangular mounting plate 216 on the base 211. That is, the second through-hole 215 is located at the bottom of the mounting bracket 21 and, when installed, faces the heat exchanger 3. The second ultraviolet component 222 includes a lamp tube 2221, for example, a U-shaped lamp tube 2221, at least a portion of which is aligned with the second through-hole 215. When installed, the lamp 2221 can be aligned with the heat exchanger 3, and the ultraviolet light emitted can pass through the second through hole 215 and shine on the heat exchanger 3 to sterilize the surface of the heat exchanger 3 and the indoor fan, frame, water tray, etc. in the irradiation area, so as to avoid secondary pollution caused by bacteria growing on the surface of the heat exchanger 3.

[0041] It should be noted that lamp 2221 can be a low-pressure mercury lamp, which emits ultraviolet light to irradiate the surface of heat exchanger 3, and also produces a small amount of ozone. Driven by the indoor fan, ozone diffuses within the casing 1, eliminating odors caused by bacteria, mold, etc. Of course, lamp 2221 can also be configured as a straight line, W-shaped, wavy, or other possible shapes.

[0042] like Figures 1 to 4As shown, the ultraviolet sterilization device 2 also includes a power supply module 23, which is located near the right end of the base 211. This power supply module 23 includes a circuit board, transformer, transistor, capacitor, resistor, etc., and is connected to an external power source via a terminal block 26. It converts the external power source into stable DC power that meets the requirements of the ultraviolet sterilization device, for example, converting 220V AC power into 12V DC power, thereby powering the first ultraviolet component 221 and the second ultraviolet component 222. A first wire through hole 2133 is provided on the third sidewall 21313 of the first rectangular mounting plate 2131, and a second wire through hole 2134 is provided on the fourth sidewall 21314. A third wire through hole 2161 is provided on the second rectangular mounting plate 216 at a position corresponding to the second wire through hole 2134. The first end of the first conductor 24 is electrically connected to the first ultraviolet component 221, and the second end passes through the first wire hole 2133 and is then electrically connected to the power supply module 23. The first end of the second conductor 25 is electrically connected to the second ultraviolet component 222, and the second end passes through the third wire hole 2161 and the second wire hole 2134 and is then electrically connected to the power supply module 23, thereby enabling the power supply module 23 to supply power to the first ultraviolet component 221 and the second ultraviolet component 222. Furthermore, two hooks 217 are symmetrically arranged on the base 211 near the power supply module 23. These hooks 217 can respectively hook the first conductor 24 and the second conductor 25, keeping the wiring neat and organized. It should be noted that the external power source can be the main power module of the wall-mounted air conditioner or an external power source for the wall-mounted air conditioner. Of course, the power supply module 23 can also be a module that stores electrical energy, such as a rechargeable battery, a storage battery, or a dry cell battery.

[0043] Continue to refer to Figures 1 to 4 The base 211 also includes a second mounting structure 218, which comprises a circular hole 2181 and two strip holes 2182, located between the ultraviolet section 22 and the power supply module 23. This allows fasteners (e.g., bolts, screws) to pass through the circular hole 2181 and the strip holes 2182 respectively and connect to the heat exchanger 3, thus enabling the ultraviolet sterilization device 2 to be installed on the wall-mounted air conditioner. Obviously, the second mounting structure 218 can also be located on the left side of the ultraviolet section 22 or the right side of the power supply module 23. Alternatively, the second mounting structure 218 can be configured as a plug extending downwards from the base 211, or as Velcro, or as a magnet, to install the ultraviolet sterilization device 2 on the wall-mounted air conditioner via plugging, bonding, magnetic adsorption, or other methods. Without departing from the basic principles of this application, those skilled in the art can flexibly choose the specific location and form of the second mounting structure 218 according to the specific application scenario, as long as it enables the ultraviolet sterilization device 2 to be installed on the wall-mounted air conditioner.

[0044] In summary, in the preferred embodiment of this utility model, by setting the ultraviolet (UV) unit 22 on the mounting bracket 21, making the UV unit 22 include a first UV component 221 and a second UV component 222, and making the irradiation directions of the UV rays emitted by the first UV component 221 and the second UV component 222 form an angle, the irradiation area of ​​the UV rays can be effectively increased, greatly improving the sterilization effect. By making the first direction and the second direction perpendicular to each other, the first direction extending along the length of the air inlet 11, and the second direction facing the heat exchanger 3, it is possible to achieve full coverage of the air inlet 11, sterilize the air entering the casing 1 through the air inlet 11, and sterilize the surface of the heat exchanger 3, as well as the indoor fan, frame, water tray, etc. located within its irradiation area, thereby better improving the air quality of the indoor space.

[0045] Of course, the alternative implementation methods described above, as well as the alternative implementation methods and preferred implementation methods, can be used in combination to create new implementation methods that are suitable for more specific application scenarios.

[0046] Furthermore, those skilled in the art will understand that although some embodiments described herein include certain features but not others included in other embodiments, combinations of features from different embodiments are intended to be within the scope of this invention and form different embodiments.
