Description

Technical Field

[0001] The utility model belongs to the technical field of air conditioning, and in particular relates to a water washing device and an air conditioner. Background Art

[0002] Common indoor pollution includes PM2.5, VOC (organic compounds) and PM10. Some of these pollutants will penetrate into residents' homes through gaps in doors and windows, while others are evaporated from furniture and generated by users' daily lives. These pollutants can harm human health through breathing, skin contact, food or water pollution, etc.

[0003] Existing technologies often use spray dust removal to absorb harmful substances from the air. Tiny water mist particles collide with dust particles and VOCs in the air, capturing them in the water droplets and thus achieving dust reduction and air purification. The higher the probability of contact and collision between dust particles, VOCs, and water mist particles, the greater the probability of capturing harmful substances (dust particles and VOCs) in the air, and the cleaner the air. Improving the probability of contact and collision between harmful substances and water mist particles, and thereby improving the water mist's ability to adsorb (capture) harmful substances, is a pressing technical challenge. Utility Model Content

[0004] Therefore, the utility model provides a water washing device and an air conditioner, which can solve the technical problem in the prior art that the probability of water mist particles contacting harmful substances in the air is low.

[0005] The utility model provides a water washing device, which is arranged on an air conditioner. The water washing device includes a water tank and an air supply component located above the water tank. A water mist generator is arranged in the inner cavity of the water tank, and an air inlet is arranged on the side wall of the water tank. The inner cavity of the water tank is connected to the inlet of the air supply component through a tortuous channel.

[0006] In some embodiments, the adsorption channel is S-shaped.

[0007] In some embodiments, a dehumidification unit is provided between the air supply assembly and the water tank, and the outlet of the zigzag passage is connected to the inlet of the air supply assembly through the dehumidification unit.

[0008] In some embodiments, the air supply assembly includes a fan and a casing mounted outside the fan, the inlet of the casing is the inlet of the air supply assembly, the outlet of the casing is the outlet of the air supply assembly, and the fan can rotate forward and reverse.

[0009] In some embodiments, a spoiler is provided in the tortuous channel.

[0010] In some embodiments, a guide portion is provided below the dehumidification portion, the zigzag channel is provided on the guide portion, the guide portion is provided with an outer peripheral surface opposite to the inner wall surface of the water tank, and the air inlet is opposite to the outer peripheral surface of the guide portion.

[0011] In some embodiments, the dehumidification part includes a dehumidification component and a first flared channel arranged below the dehumidification component with the large end facing upward, the large end of the first flared channel is adjacent to the dehumidification component, and the small end of the first flared channel is connected to the outlet of the tortuous channel.

[0012] In some embodiments, the dehumidification part also includes a second flared channel arranged above the dehumidification component, the large end of the second flared channel faces downward and is adjacent to the dehumidification component, and the small end of the second flared channel is connected to the inlet of the air supply component.

[0013] In some embodiments, a sterilization device is also provided in the water tank.

[0014] The utility model provides an air conditioner, comprising the water washing device.

[0015] The operation of the air supply component creates a negative pressure (a pressure lower than the marked atmospheric pressure) at the inlet area of ​​the air supply component. This negative pressure causes the air outside the water washing device to enter the inner cavity of the water tank through the air inlet. The water mist generator operates to gradually atomize the water in the water tank. The atomized water vapor floats upward, and the water vapor is initially mixed with the air entering the water tank through the air inlet before entering the tortuous channel under the action of negative pressure. The water vapor collides with dust particles, VOCs, etc. in the air, and some dust particles and VOCs are captured by the water vapor. Due to the tortuous channel, the path of the mixed gas (the mixed gas includes water vapor and the air entering the water tank through the air inlet) becomes longer before reaching the air supply component. The longer path increases the probability and duration of collision and contact between water vapor and harmful substances (harmful substances include dust particles and VOCs), thereby improving the air purification efficiency and helping to improve the air quality.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] In the description of the present invention, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0026] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0027] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of this utility model.

[0028] See also Figure 1-4 As shown, a water washing device is arranged on an air conditioner, and the water washing device includes a water tank 1, an air supply component 2 located above the water tank 1, a water mist generator 3 is arranged in the inner cavity of the water tank 1, and an air inlet 101 is arranged on the side wall of the water tank 1. The inner cavity of the water tank 1 is connected to the inlet of the air supply component 2 through a tortuous channel 4.

[0029] The tortuous channel 4 can extend the airflow path from the inner cavity of the water tank 1 to the inlet of the air supply component 2 to be greater than the straight-line distance.

[0030] The operation of the air supply component 2 generates a negative pressure (a pressure lower than the marked atmospheric pressure) in the inlet area of ​​the air supply component 2. This negative pressure causes the air outside the water washing device to enter the inner cavity of the water tank 1 through the air inlet 101. The water mist generator 3 operates to gradually atomize the water in the water tank 1. The atomized water vapor floats upward. The water vapor is initially mixed with the air entering the water tank 1 through the air inlet 101 and then enters the tortuous channel 4 under the action of negative pressure. The water vapor collides with the dust particles, VOCs, etc. in the air, and some dust particles and VOCs are captured by the water vapor. Because the tortuous channel 4 makes the path of the mixed gas (the mixed gas includes water vapor and the air entering the water tank 1 through the air inlet 101) longer before reaching the air supply component 2, the longer path increases the probability and duration of the collision and contact between water vapor and harmful substances (harmful substances include dust particles and VOCs), thereby improving the air purification efficiency and helping to improve the air quality.

[0031] Specifically, water tank 1 contains clean water, such as tap water or condensed water. Water mist generator 3 includes an ultrasonic atomizer, which vibrates the water in tank 1 into a mist containing water droplets with a particle size of approximately 100 μm. The mist floats above the liquid water in tank 1 and captures harmful particles in the air. Multiple water inlets and multiple zigzag channels 4 are provided to improve air purification efficiency.

[0032] Preferably, Figure 3 As shown, the adsorption channel is S-shaped.

[0033] The adsorption channel is arranged in an S shape, which is beneficial to processing and production and improves production efficiency.

[0034] Preferably, Figure 2-3 As shown, a dehumidifier 5 is provided between the air supply component 2 and the water tank 1 , and the outlet of the zigzag channel 4 is connected to the inlet of the air supply component 2 via the dehumidifier 5 .

[0035] After the water vapor and harmful substances are fully contacted and mixed in the tortuous channel 4, most of the harmful substances are captured in the water vapor. When the water vapor flows through the dehumidification part 5, the tiny liquid particles in the water vapor are adsorbed by the dehumidification part 5. Since the harmful substances are captured by the tiny water droplets (tiny water droplets) in the water vapor, the harmful substances in the air entering the fan 201 are greatly reduced, thereby improving the quality of the indoor air.

[0036] The dehumidification component 501 can be a stainless steel oil mist separation filter, a polyurethane foam sponge, etc.

[0037] Preferably, Figure 2 As shown, the air supply component 2 includes a fan 201 and a casing 202 mounted outside the fan 201. The inlet of the casing 202 is the inlet of the air supply component 2, and the outlet of the casing 202 is the outlet of the air supply component 2. The fan 201 can rotate forward and reverse.

[0038] Forward rotation of fan 201 causes air in water tank 1 to enter casing 202 through its inlet and exit through its outlet; this allows air (water mist and air) to flow through zigzag passage 4 and past dehumidifier 5. Reverse rotation of fan 201 causes outside air to enter casing 202 through its inlet and exit through its outlet. Air exiting casing 202 passes through dehumidifier 5, separating some of the moisture within it and causing it to drip downward. This dripping moisture then enters water tank 1. In this way, both forward and reverse rotation of fan 201 ensure continuous operation of dehumidifier 5.

[0039] The fan 201 is preferably a centrifugal fan. The airflow generated when the centrifugal fan is reversed is relatively small. However, the moisture adsorbed by the dehumidification component can also be separated from the dehumidification part to a certain extent under the action of airflow and gravity.

[0040] Preferably, Figure 3 As shown, a spoiler 601 is provided in the zigzag channel 4 .

[0041] By arranging the spoiler 601 in the zigzag channel 4, the airflow becomes turbulent when water vapor and harmful substances flow in the zigzag channel 4. The turbulent airflow can increase the probability of collision and contact between tiny water droplets and harmful substances, which is beneficial to improving the capture of harmful substances.

[0042] Preferably, Figure 3 As shown, a guide portion 602 is provided below the dehumidification portion 5, the zigzag channel 4 is provided on the guide portion 602, the guide portion 602 is provided with an outer peripheral surface opposite to the inner wall surface of the water tank 1, and the air inlet 101 is opposite to the outer peripheral surface of the guide portion 602.

[0043] The air entering the water tank 1 from the air inlet 101 first collides with the outer peripheral surface of the guide portion 602, slowing down the flow of the air so that the harmful substances in the air and the water vapor can fully mix, collide and contact.

[0044] Preferably, Figure 3 As shown, the dehumidification part 5 includes a dehumidification component 501 and a first flared channel 701 arranged below the dehumidification component 501 with the large end facing upward, the large end of the first flared channel 701 is adjacent to the dehumidification component 501, and the small end of the first flared channel 701 is connected to the outlet of the tortuous channel 4.

[0045] The airflow flowing out of the zigzag channel 4 flows in a diffused manner in the first expansion channel 701, which increases the contact area between the airflow and the dehumidification component 501, improves the dehumidification effect of the airflow, and effectively avoids or reduces the capture of water vapor containing harmful substances into the room.

[0046] Preferably, Figure 3 As shown, the dehumidification part 5 also includes a second flared channel 702 arranged above the dehumidification component 501, the large end of the second flared channel 702 faces downward and is adjacent to the dehumidification component 501, and the small end of the second flared channel 702 is connected to the inlet of the air supply component 2.

[0047] By setting up a second flared channel 702, the airflow flowing through the dehumidification component 501 shrinks and flows into the air supply component 2 after passing through the second flared channel 702, which is beneficial to reducing the flow resistance of the airflow after flowing through the dehumidification component 501. For the air supply component 2, when the speed of the airflow flowing out of the air supply component 2 is made consistent, the volume and power of the air supply component 2 can be reduced, thereby reducing energy consumption.

[0048] Preferably, Figure 3 As shown, a sterilizing device 8 is also provided in the water tank 1 .

[0049] After the air enters the water tank 1 from the air inlet 101, the sterilization device 8 can sterilize the air to further improve the air quality. The sterilization device 8 may include an electrolyzed water sterilization device 8, a hydrogen peroxide sterilization device 8, or an ultraviolet sterilization device 8.

[0050] The utility model provides an air conditioner, comprising the water washing device.

[0051] The water washing device is detachably installed at the bottom of the air conditioner for easy maintenance.

[0052] like Figure 5 As shown, the working process of the water washing device is:

[0053] Step 1: The user turns on the water washing function (the water washing function can be turned on only when the air conditioner is powered on);

[0054] Step 2: Detect the water level. If the water level is less than L, remind the user to add water. If the water level is greater than or equal to L, proceed to the next step.

[0055] Step 3: Turn on the sterilization device 8 (ultraviolet sterilization module) in the water tank 1 and run it for 5 minutes;

[0056] Step 4: Turn on the fan 201 and the ultrasonic water mist generator to wash the indoor air;

[0057] Step 5: The water washing function continues to operate;

[0058] Step 6: If the water washing device receives a signal to turn off the water washing function, the next step is executed; if the water washing device does not receive a signal to turn off the water washing function, the next step is executed;

[0059] Step 7: Turn off the fan 201, the ultrasonic water mist generating device and the sterilizing device 8.

[0060] It is easy for those skilled in the art to understand that, under the premise of no conflict, the advantageous technical features of the above-mentioned methods can be freely combined and superimposed.

The above description is only a preferred embodiment of the present invention.
