The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0032] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0033] In the present invention, unless otherwise specified, the directional words used, such as "up" and "down", usually refer to the directions shown in the drawings, or to the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention.

[0034] In order to solve the problem that the water-washed air technology in the prior art has poor dust removal and adsorption effects on indoor air, the present application provides an air treatment device and an air conditioner having the same.

[0035] like Figure 1 and Figure 2 As shown, the air handling device includes a housing 10 and a venturi tube 20. The housing 10 has an air inlet 11, a mounting cavity 12 and an exhaust port 13, and water is stored in the mounting cavity 12. The venturi tube 20 is arranged in the mounting cavity 12, and the venturi tube 20 includes a contraction tube section 21, a throat 22 and a diffusion tube section 23 connected in sequence. The contraction tube section 21 is connected to the air inlet 11, and the throat 22 has a liquid inlet hole 221. The water in the mounting cavity 12 enters the throat 22 through the liquid inlet hole 221; the end of the diffusion tube section 23 away from the contraction tube section 21 is located below the liquid level of the water. Among them, the exhaust port 13 is located above the liquid inlet hole 221.

[0036] By applying the technical solution of this embodiment, when it is necessary to adsorb and settle dust and harmful particles in the indoor air, the indoor air is introduced into the contraction tube section 21 of the venturi tube 20 through the air inlet 11. According to Bernoulli's theorem, the faster the fluid flow rate, the smaller the pressure. When the airflow passes through the contraction tube section 21, the path is increased, and the flow time remains unchanged. Therefore, the gas flow rate is accelerated and the flow rate reaches a maximum at the throat 22. Therefore, the pressure at the throat 22 is the minimum. The water stored in the installation cavity 12 is sucked into the venturi tube 20 through the liquid inlet hole 221. Under the action of the high-speed fluid, the inhaled water is crushed into droplets with extremely small particle size and interacts with the inhaled air to form water mist. The water mist will settle and dissolve the dust and harmful particles in the air to achieve the effect of purifying the air. The purified air and water mist both enter the diffusion pipe section 23. Since the diffusion pipe section 23 is immersed in the water, the water mist can be removed to prevent it from being blown into the room. The purified air is finally blown out from the exhaust port 13 to achieve the purpose of washing the air with water and removing dust and harmful particles, thereby solving the problem of poor dust removal and adsorption effect of water washing air technology on indoor air in the prior art, and improving the air treatment efficiency of the air treatment device.

[0037] In this embodiment, the venturi tube 20 is a commonly used device in fluid mechanics. Its design is based on Bernoulli's theorem, which describes that in a stable flow, the velocity of the fluid is inversely proportional to the pressure. When liquid passes through the throat 22, the high-speed flowing gas causes the fluid to break and atomize, making the water particle size much smaller than 150um, and the dust reduction effect is best when the droplet size is between 50 and 150um, thereby improving the dust removal effect of the air treatment device.

[0038] In this embodiment, the contraction pipe section 21 , the throat pipe 22 and the diffusion pipe section 23 are coaxially arranged.

[0039] Optionally, the air treatment device further includes a pipeline, and both ends of the pipeline are respectively connected to the water and the liquid inlet hole 221 to introduce the water into the liquid inlet hole 221.

[0040] like Figure 1As shown, the air handling device further includes a partition 30, which is arranged in the housing 10 to separate the installation cavity 12 into a first chamber 121 and a second chamber 122. The first chamber 121 is located above the second chamber 122 and is connected to the air inlet 11, and the air outlet 13 is connected to the second chamber 122. The partition 30 has a through hole 31, and the first chamber 121 is connected to the contraction tube section 21 through the through hole 31. Among them, the orthographic projection of the through hole 31 on the contraction tube section 21 is located on the contraction tube section 21 or in the contraction tube section 21. In this way, the installation cavity 12 is divided into the first chamber 121 and the second chamber 122 arranged up and down by the partition 30, the first chamber 121 is used to buffer the indoor air, and the second chamber 122 is used to place the venturi tube 20, thereby making the space layout inside the housing 10 more reasonable and compact, and improving the internal space utilization rate of the housing 10. At the same time, the above-mentioned arrangement of the through hole 31 ensures that the air inlet 11 can be communicated with the contraction tube section 21 to realize the air intake of the venturi tube 20 .

[0041] In this embodiment, the orthographic projection of the through hole 31 on the contraction tube section 21 is located on the contraction tube section 21, and the indoor air enters the contraction tube section 21 through the air inlet 11 and the through hole 31 in sequence to improve the flow smoothness of the indoor air.

[0042] Optionally, there is one venturi tube 20; or, there are multiple venturi tubes 20, and the multiple venturi tubes 20 are arranged at intervals along the length direction and / or width direction of the housing 10; or, the multiple venturi tubes 20 are arranged at intervals along the circumference of the housing 10. In this way, the above arrangement makes the number of venturi tubes 20 more flexible to meet different usage requirements and working conditions, and also improves the processing flexibility of the staff; on the other hand, when there are multiple venturi tubes 20, the multiple venturi tubes 20 can improve the processing capacity and effect of the air treatment device, and are suitable for rooms of different sizes or different air quality requirements.

[0043] In this embodiment, there are four venturi tubes 20 , and the four venturi tubes 20 are arranged at intervals along the length direction of the casing 10 .

[0044] It should be noted that the number of the venturi tubes 20 is not limited thereto, and can be adjusted according to working conditions and usage requirements. Optionally, the number of the venturi tubes 20 is two, three, five, six, or more.

[0045] In other embodiments not shown in the drawings, a plurality of venturi tubes are arranged at intervals along the width direction of the casing.

[0046] In other embodiments not shown in the drawings, a plurality of venturi tubes are arranged at intervals along the circumference of the casing.

[0047] In other embodiments not shown in the drawings, a plurality of venturi tubes are arranged at intervals along the length direction and the width direction of the casing.

[0048] Optionally, there is one air inlet 11; or, there are multiple air inlets 11, and the multiple air inlets 11 are arranged at intervals along the height direction and / or circumference of the housing 10; and / or, there is one exhaust port 13; or, there are multiple exhaust ports 13, and the multiple exhaust ports 13 are arranged at intervals along the height direction and / or circumference of the housing 10. In this way, the above-mentioned setting, on the one hand, makes the selection of the number of air inlets 11 and exhaust ports 13 more flexible to meet different usage requirements and working conditions, and also improves the processing flexibility of the staff; on the other hand, when there are multiple air inlets 11 and / or exhaust ports 13, it can ensure that the air treatment device evenly inhales and exhausts air in different directions, which can not only improve the uniformity and efficiency of air treatment, but also effectively avoid dead corners, so that the air quality of the entire room is improved.

[0049] In this embodiment, there is one air inlet 11 and two air outlets 13 .

[0050] It should be noted that the number of the air inlets 11 is not limited thereto, and can be adjusted according to working conditions and usage requirements. Optionally, the number of the air inlets 11 is two, three, four, five, or more.

[0051] In other embodiments not shown in the drawings, a plurality of air inlets are arranged at intervals along the height direction of the casing.

[0052] In other embodiments not shown in the drawings, a plurality of air inlets are arranged at intervals along the circumference of the casing.

[0053] In other embodiments not shown in the drawings, a plurality of air inlets are arranged at intervals along the height direction and the circumferential direction of the casing.

[0054] It should be noted that the number of the exhaust ports 13 is not limited thereto and can be adjusted according to working conditions and usage requirements. Optionally, the number of the exhaust ports 13 is three, four, five, or more.

[0055] In other embodiments not shown in the drawings, a plurality of exhaust ports are arranged at intervals along the height direction of the casing.

[0056] In other embodiments not shown in the drawings, a plurality of exhaust ports are arranged at intervals along the circumference of the casing.

[0057] In other embodiments not shown in the drawings, a plurality of exhaust ports are arranged at intervals along the height direction and the circumferential direction of the casing.

[0058] like Figure 2As shown, the contraction pipe section 21 includes a straight pipe section 211 and a tapered pipe section 212, and the straight pipe section 211 is connected to the throat pipe 22 through the tapered pipe section 212. In the direction from the straight pipe section 211 to the throat pipe 22, the inner diameter of the tapered pipe section 212 gradually decreases. In this way, the above arrangement can effectively increase the flow rate at the throat pipe 22, reduce the pressure, and improve the atomization effect of the water liquid, so that the particles and harmful substances in the air are more easily captured by the water liquid, further improving the purification efficiency of the air treatment device.

[0059] Optionally, the air treatment device further includes a mounting frame and a fan. The mounting frame is arranged in the straight pipe section 211. The fan is arranged on the mounting frame to draw air into the contraction pipe section 21 through the air inlet 11. In this way, by arranging the fan and the mounting frame, it is possible to ensure that the indoor air passes through the venturi tube 20 stably and efficiently, thereby improving the air treatment efficiency. At the same time, the above arrangement makes the disassembly and assembly of the fan easier and simpler, and reduces the difficulty of disassembly and assembly.

[0060] Optionally, the air treatment device further comprises a support structure, which is arranged in the installation cavity 12 to support the venturi tube 20. There is a preset distance between the end of the diffuser tube section 23 away from the contraction tube section 21 and the inner bottom surface of the installation cavity 12. In this way, the above arrangement can ensure the stable operation of the venturi tube 20, and avoid the displacement of the venturi tube 20 due to vibration, which affects the air treatment effect. At the same time, the above arrangement can also effectively prevent water backflow, and ensure the long-term stable operation of the air treatment device.

[0061] Optionally, the air treatment device further includes a sterilization module and a detection device. The sterilization module is disposed in the installation cavity 12, and the detection device is disposed in the installation cavity 12 to detect the height of the water liquid in the installation cavity 12. In this way, by providing the sterilization module and the detection device, bacteria and viruses in the water liquid can be effectively killed, the sanitation and safety of the atomized water vapor can be ensured, and a healthier and safer air environment can be provided for users.

[0062] Optionally, the sterilization module is an ultraviolet sterilization device.

[0063] In this embodiment, the air treatment device further includes a control module, and the control module is electrically connected to the detection device, the sterilization module, and the fan. When the detection value of the detection device is greater than or equal to the preset liquid level value, the sterilization module is controlled to start by the control module, and after the sterilization module runs for a preset time t, the fan is controlled to start by the control module. In this way, the above-mentioned intelligent control method can ensure sterilization and air purification when there is sufficient water, improve the safety and efficiency of the operation of the air treatment device, and can also effectively avoid energy waste caused by excessive operation, saving the user's use cost.

[0064] Optionally, the air treatment device further includes a liquid supply device, which is in communication with the installation cavity 12, for supplying liquid into the installation cavity 12. The liquid supply device is electrically connected to the control module, and when the detection value of the detection device is less than a preset liquid level value, the liquid supply device is controlled by the control module to supply liquid into the installation cavity 12. In this way, by setting an intelligent connection between the liquid supply device and the control module, water can be automatically replenished, which not only ensures the continuous operation of the air treatment device, but also effectively avoids the decline in treatment effect caused by insufficient water, and provides users with more stable and reliable air treatment services.

[0065] Optionally, the air treatment device further includes an alarm module, which is electrically connected to the control module. When the detection value of the detection device is less than a preset liquid level value, the control module controls the alarm module to send an alarm signal. In this way, the alarm module can promptly remind the user to replenish water to avoid the air treatment device from being unable to operate normally due to lack of water, which not only improves the user experience, but also effectively avoids air treatment device failures caused by human negligence, thereby extending the service life of the air treatment device.

[0066] Optionally, the speed of the fan is greater than or equal to 70 m / s and less than or equal to 90 m / s. In this way, by controlling the speed of the fan, it is possible to ensure that the air treatment device operates efficiently while maintaining a low noise level, thereby improving user comfort.

[0067] In this embodiment, the speed of the fan is 90 m / s. Thus, at the above speed, the Venturi tube 20 can control the water mist particle size within 50-150 um, and the higher the speed, the smaller the water mist particle size, thereby controlling the size of the water mist.

[0068] like Figure 3 As shown, the present application also provides an air conditioner, comprising the above-mentioned air treatment device.

[0069] Optionally, the air conditioner is a cabinet air conditioner.

[0070] In this embodiment, the air handling device is installed on the lower half of the air conditioning cabinet, and the air inlet 11 and the air outlet 13 of the air handling device are both arranged on the lower side of the air conditioning cabinet.

[0071] In this embodiment, the control method of the air treatment device is as follows:

[0072] Step 1: Power on the air conditioner;

[0073] Step 2: Detect the water level. If the water level is less than L, the user is reminded to add water. The next step is not performed until the water level is greater than L.

[0074] Step 3: Turn on the UV sterilization module and run it for 5 minutes to sterilize the water in the air handling device to prevent the purified air from blowing bacteria growing in the housing 10 into the room;

[0075] Step 4: Start the fan of the air handling device. At this time, the air handling device begins to remove dust from the indoor air.

[0076] During the continuous operation of the air treatment device, it is determined in real time whether the user turns off the air treatment function.

[0077] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0078] The air handling device includes a housing and a venturi tube. The housing has an air inlet, a mounting cavity and an exhaust port. Water is stored in the mounting cavity. The venturi tube is arranged in the mounting cavity. The venturi tube includes a contraction tube section, a throat tube and a diffusion tube section connected in sequence. The contraction tube section is connected to the air inlet. The throat tube has a liquid inlet hole. The water in the mounting cavity enters the throat tube through the liquid inlet hole. The end of the diffusion tube section away from the contraction tube section is located below the liquid level of the water. The exhaust port is located above the liquid inlet hole. In this way, when it is necessary to adsorb and settle the dust and harmful particles in the indoor air, the indoor air is introduced into the contraction section of the Venturi tube through the air inlet. According to Bernoulli's theorem, the faster the fluid flow rate, the smaller the pressure. When the airflow passes through the contraction section, the path is increased, and the flow time remains unchanged. Therefore, the gas flow rate is accelerated and the flow rate reaches the maximum at the throat. Therefore, the pressure at the throat is the smallest, and the water stored in the installation cavity is sucked into the Venturi tube through the liquid inlet hole. Under the action of high-speed fluid, the inhaled water is crushed into droplets with extremely small particle size and interacts with the inhaled air to form water mist. The water mist will settle and dissolve the dust and harmful particles in the air to achieve the effect of purifying the air. The purified air and water mist both enter the diffusion pipe section. Since the diffusion pipe section is immersed in water, the water mist can be removed to prevent it from blowing into the room. The purified air is finally blown out from the exhaust port to achieve the purpose of washing the air with water and removing dust and harmful particles, thereby solving the problem of poor dust removal and adsorption effect of water-washed air technology on indoor air in the prior art, and improving the air treatment efficiency of the air treatment device.
