The utility model discloses an air purification module, air purification module can air-purifying to dust collecting device in can the self-cleaning air purification module simplifies dust collecting module's clean mode, improves dust collection efficiency, reduces dust collecting device dismouting operation.

Referring to fig. 1, in an embodiment of the air purification module 100 of the present invention, the air purification module 100 includes a housing 110, a water washing device 120, a dust collecting device 130, and a cleaning member 140. The housing 110 has an air inlet 111, an air outlet 112, and a clean air duct communicating the air inlet 111 and the air outlet 112. The water washing device 120 is disposed in the purification air duct and is adapted to wash air passing through the purification air duct. The dust collector 130 is disposed above the washing device 120. The cleaning member 140 is provided to the cleaning duct, and the cleaning member 140 is adapted to use water for cleaning the dust collecting device 130 when the water is supplied to the cleaning member 140.

Specifically, the shape of the casing 110 may be various, and in order to better fit with the air conditioner, the shape of the casing 110 may be set according to the model of the air conditioner indoor unit, which is not particularly limited herein, and is described as a cylindrical configuration. The housing 110 is generally cylindrical and extends in the up-down direction, for example, the housing 110 may be square or circular, and the purge air duct in the housing 110 also extends in the up-down direction. The bottom of the shell 110 is provided with an air inlet 111, and the air inlet 111 is communicated with the lower end of the purification air duct; the housing 110 has an air outlet 112 at the top thereof, and the air outlet 112 is communicated with the upper end of the purification air duct.

When the air purification module 100 purifies air, the air enters the purification air duct from the air inlet 111 and flows along the purification air duct from bottom to top, and the air is washed and purified by the washing device 120 when passing through the washing device 120; the purified air continues to flow upward, and when passing through the dust collecting device 130, the air is again dedusted by the dust collecting device 130, so that the air is further purified into cleaner air, and finally, the cleaner air is blown out from the air outlet 112 through the upper end of the purification air duct.

The dust collecting device 130 is tiled along the cross section of the purification air duct to cover the cross section of the purification air duct as much as possible, so that the air in the purification air duct can pass through the dust collecting device 130, and the dust removal efficiency is improved. As for the dust removing manner of the dust collecting device 130, the dust collecting device 130 is an electrostatic dust collecting device, which is a dust collecting method of electrically adsorbing dust particles to electrodes by ionizing gas by generating an electrostatic field. In an electrostatic field, air molecules are ionized into positive ions and electrons, and the electrons encounter dust particles in the process of running to the positive electrode, so that the dust particles are negatively charged, adsorbed to the positive electrode and collected. After the dust collecting device 130 is used for a period of time, only water needs to be supplied to the cleaning member 140, and the dust collecting device 130 is cleaned by the cleaning member 140, so that the dust collecting device 130 is automatically cleaned without manually disassembling and assembling the dust collecting device 130 by a user.

The cleaning member 140 may be any one or more of a nozzle 140b, a nozzle, a steam generator 140a, and a drain plate. The water droplets or mist formed by the cleaning members 140 eventually flow downward to be discharged outward or return to the water supply tank 160 for reuse. In theory, the cleaning member 140 may be disposed above the dust collecting device 130, may be disposed below the dust collecting device 130, and may be disposed around the dust collecting device 130. The particular type of cleaning elements 140 may be varied.

Referring to fig. 1, for example, when the cleaning member 140 is a steam generator 140a, the steam generator 140a can also be disposed above, below, or laterally to the dust collecting device 130. When water is supplied to the steam generator 140a, the steam generator 140a heats and evaporates the water to form high-temperature steam, and blows the high-temperature steam toward the dust collecting device 130, and the high-temperature steam can not only adsorb and dissolve dust on the dust collecting device 130, but also kill microorganisms such as bacteria on the dust collecting device 130 at a high temperature.

Referring to fig. 3, for another example, when the cleaning member 140 is a nozzle 140b or a nozzle (not shown), the nozzle 140b can be disposed above, below, or laterally to the dust collecting device 130. When water is supplied to the spray head 140b, the spray head 140b can spray the water toward the dust collecting device 130, and dust on the dust collecting device 130 is dissolved in the water and carried away by the water flow.

For another example, when the cleaning member 140 is a water leaking plate (not shown), the water leaking plate has a plurality of water leaking holes, and when water is supplied to the water leaking plate, the water flows down to the dust collecting device 130 through the plurality of water leaking holes, and the dust on the dust collecting device 130 is dissolved in the water and carried away by the water flow. After the washing is finished, when the air purification module 100 is opened to purify the air, the air can pass through the water leakage holes of the water leakage plate and flow upwards, and the air flow is not obstructed.

The technical scheme of the utility model, through will purifying and set up washing piece 140 in the wind channel, washing piece 140 is used for when supplying water to washing piece 140, is used for wasing dust collecting device 130 with water, realizes dust collecting device 130 self-cleaning, need not the manual dismouting dust collecting device 130 of user, reduces the operation of wasing dust collecting device 130, and then avoids taking place because of the condition that many times unpick and wash and cause dust collecting device 130 to lead to the fact the circular telegram is bad, and the efficiency of removing dust is greatly improved, extension dust collecting device 130's life.

Referring to fig. 1, based on the above embodiment, the water washing device 120 includes a rotating body 121 and a driving member 122, the rotating body 121 is rotatably disposed in the purifying air duct, and the driving member 122 is connected to the rotating body 121. The rotating body 121 is adapted to rotate at a high speed by the driving member 122 when water is applied to the rotating body 121, and throw the water in a radial direction thereof to form countless water drops having an extremely small particle size. The water drops absorb impurities in the air flow and take away the impurities, and the supergravity water throwing and air purifying are realized. For example, fine particles, pollen, biological bacteria, volatile organic compounds (such as formaldehyde and benzene) in the purified air. In addition, the water drops are mixed into the air, and the effect of humidifying the air can be achieved. The purified air is blown out to the indoor environment through the outlet 112.

The rotating body 121 actually includes a rotating frame and a plurality of screens (not shown) provided on the rotating frame. Wherein a part of the screens can surround the rotating bracket along the circumference of the rotating bracket and are sequentially arranged at intervals along the radial direction of the rotating bracket; the other part of the screen cloth can be sequentially distributed in a flat-laying shape at intervals along the rotating axis direction of the rotating bracket. When the rotating body 121 rotates at a high speed, the rotating body 121 throws out the water sprayed by the water applying member 123 along the radial direction, the thrown water meets the screen mesh and is cut into a plurality of fine water particles by the screen mesh, and the water particles scour the air and fully contact with the air, so that various impurities in the air are effectively blended into the air and taken away, and the purification efficiency is greatly improved.

The rotation speed at which the driver 122 rotates the rotating body 121 is not limited in practice. However, it is considered that when the linear velocity of the outer edge of the rotating body 121 is too small, the velocity of the water thrown out by the rotating body 121 is small, and the air cleaning effect is poor, and when the linear velocity of the outer edge of the rotating body 121 is too large, the energy consumption for rotating the rotating body 121 is large and the noise generated is large, and further, the improvement of the air cleaning effect by continuously increasing the linear velocity of the outer edge of the rotating body 121 is small.

Therefore, in the present embodiment, when the air purification module 100 is required to operate, the linear velocity of the outer edge of the rotating body 121 is 10m/s to 45 m/s. Such as but not limited to: 10m/s, 15m/s, 18m/s, 20m/s, 25m/s, 30m/s, 35m/s, 38 m/s. The linear velocity of the outer edge of the rotating body 121 is limited to 10m/s to 45m/s, so that the velocity of the water thrown out by the rotating body 121 is ensured to be high, and the noise generated by the rotation of the rotating body 121 is small.

In order to supply water to the rotating body 121, the water washing device 120 further includes a water application member 123, and the water application member 123 may be disposed above or below the rotating body 121, and the water application member 123 is communicated with a water source through a water pump to spray water from the water source to the rotating body 121. The water application member 123 may be a spray head, a spray pipe, or a water leakage plate. As for the water source, the water source may be a water tank provided by the user himself or a water supply tank 160 provided inside the housing 110, which will be described in detail later.

Referring to fig. 1, in an embodiment, the air purification module 100 further includes a water supply tank 160, the water supply tank 160 is disposed in the housing 110, and the water supply tank 160 is communicated with the water washing device 120 and/or the cleaning member 140 and is used for supplying water to the water washing device 120 and/or the cleaning member 140. Specifically, the water washing device 120 and the washing member 140 are both communicated with the water supply tank 160. As for the specific manner in which both the water washing device 120 and the washing member 140 communicate with the water supply tank 160, the following two embodiments are exemplified herein:

referring to fig. 1, in one embodiment, the air cleaning module 100 further includes a first water pump 101 and a second water pump 102, the first water pump 101 communicating the water supply tank 160 with the water washing device 120, and the second water pump 102 communicating the water supply tank 160 with the cleaning member 140.

Specifically, the first water pump 101 and the second water pump 102 are both provided in the water supply tank 160. The first water pump 101 connects the water supply tank 160 to the water application member 123 of the water washing apparatus 120, and the second water pump 102 connects the water supply tank 160 to the washing member 140. The first water pump 101 and the second water pump 102 are independently operated without interference, so that the water can be independently supplied to the washing part 140 and the water applying part 123 of the water washing device 120.

Referring to fig. 2, in another embodiment, the difference from the previous embodiment is that the air purification module 100 further includes a first water pump 101 and a reversing valve 103, the reversing valve 103 has a water inlet end, a first water outlet end and a second water outlet end, the water inlet end is communicated with the water supply tank 160 through the first water pump 101, the first water outlet end is communicated with the water washing device 120, and the second water outlet end is communicated with the cleaning member 140.

Specifically, the first outlet end of the reversing valve 103 is communicated with the water applying member 123 of the water washing device 120, and the second outlet end is communicated with the washing member 140. The reversing valve 103 is an electromagnetic reversing valve 103, and the reversing valve 103 can switch the opening and closing of the first water outlet end and the second water outlet end. For example, when the water supply for the cleaning member 140 is required, the reversing valve 103 is controlled to open the first water outlet end and close the second water outlet end, so that the water can be supplied to the cleaning member 140 independently. On the contrary, when water needs to be supplied to the water applying member 123, the reversing valve 103 is controlled to open the second water outlet end and close the first water outlet end, so that water can be supplied to the water applying member 123 independently. Therefore, a water pump can be omitted, and the effects of saving cost and power consumption can be achieved.

The above two embodiments, in which the water washing device 120 and the washing member 140 are both in communication with the water supply tank 160, may be alternatively selected according to the needs, and are not particularly limited herein.

In addition, the small-particle-size negative ions also have good biological activity, are easy to permeate the blood brain barrier of a human body, enter the human body to exert the biological effect, and are beneficial to improving the physical health state of a user and prolonging the service life.

Based on this, it is considered that in the process of cleaning the dust collecting device 130 by the cleaning member 140, the water drops applied to the dust collecting device 130 by the cleaning member 140 may drop downwards to the negative ion generating device 170, and may cause short circuit of electrical components or circuits on the negative ion generating device 170. To avoid this, a waterproof structure (not shown) is optionally provided at the negative ion generating device 170 to prevent water applied from the cleaning member 140 from dropping to the negative ion generating device 170. The waterproof structure can be a water baffle above the anion generator, or a waterproof adhesive tape, and the waterproof adhesive tape is used for wrapping wires and the like.

In addition, a water filtering member 180 is further provided between the negative ion generating device 170 and the rotating body, and the water filtering member 180 is used for filtering moisture in the air passing through the water filtering member 180 from the cleaning air duct, thereby preventing the moist air from damaging the negative ion generating device 170.

Based on any of the above embodiments, the air purification module 100 further includes a fan device 150, and the fan device 150 is disposed above the cleaning member 140 to drive air to enter the purification air duct from the air inlet 111 and to be blown out from the air outlet 112.
