Description
Technical Field
[0001] This application relates to the field of air conditioning, and more particularly to an air conditioner and its water-washing fresh air device. Background Technology
[0002] With the development of air treatment technology, equipment for purifying and humidifying air is becoming more and more common. Household appliances such as air conditioners are gradually being equipped with water washing devices and fresh air devices to increase product functionality and improve user experience.
[0003] Patent application CN112556009A discloses a water-washing fresh air device comprising a water tank, a water-washing component, a fresh air component, and an air-driven unit. The water tank includes a first chamber containing a washing liquid. The water-washing component is disposed within the first chamber and is at least partially immersed in the washing liquid, thereby causing the washing liquid to form a water film that purifies the air entering the water tank. The water tank has an air outlet and at least two air inlets. The air-driven unit is connected to the air outlet to drive air into the water tank and out through the air outlet. The fresh air component is connected to any one of the at least two air inlets to provide outdoor air to the water tank. This invention provides a water-washing fresh air device that achieves both water-washing and fresh air functions while reducing costs.
[0004] Regarding the above technical solution, the fresh air only passes through the inner cavity of the water tank and is cleaned by a water film. The contact area between the fresh air and the water film is small, resulting in poor water washing effect of the fresh air. Summary of the Invention
[0005] To improve the water washing effect of fresh air, this application provides an air conditioner and a water washing fresh air device thereof.
[0006] Firstly, the water-washing fresh air device provided in this application adopts the following technical solution:
[0007] A water-washing fresh air device includes a water tank, an air inlet mechanism, and a water washing mechanism. The water washing mechanism includes a rotating cylinder, several blades, and a water washing motor. An air outlet is provided on the top of the water tank. The rotating cylinder is rotatably disposed inside the water tank, and the water washing motor drives the rotating cylinder to rotate. The blades are evenly spaced along the circumference of the rotating cylinder, and the blades are also evenly spaced along the length of the rotating cylinder. Several air outlets are provided on the circumferential sidewall of the rotating cylinder, and the air outlets are located between two adjacent blades arranged circumferentially on the rotating cylinder. The air inlet mechanism drives air into the rotating cylinder.
[0008] By adopting the above technical solution, when in use, the water level in the water tank is higher than the rotating cylinder. The air intake mechanism drives fresh air into the rotating cylinder, which is driven to rotate by the water washing motor. At the same time, the fresh air is divided into several small airflows by the air outlet and emerges from underwater. The rotation of the rotating cylinder causes the blades to rotate, thereby further dispersing the small airflows underwater, so that the airflow is fully washed, improving the water washing effect of the air. The airflow is divided into multiple small airflows, improving the water mist carrying capacity and increasing indoor humidity.
[0009] Optionally, the end of the blade away from the rotating cylinder is provided with bristles, and at least one water mist rod is provided on the inner wall of the water tank. When the rotating cylinder rotates, the bristles brush over the water mist rod.
[0010] By adopting the above technical solution, the water mist content in the water tank is increased by setting a brush to brush over the water mist rod, while the water mist diameter is reduced, making it easier for the airflow to carry the water mist out of the water tank, thereby increasing the indoor humidity. The higher water mist content in the water tank further allows for full contact with the airflow, and the water mist adsorbs and settles the tiny particles in the airflow, thus improving the washing effect.
[0011] Optionally, the water mist rod includes a water removal rod and a misting rod, wherein the horizontal height of the water removal rod is lower than that of the misting rod.
[0012] By adopting the above technical solution, the horizontal height of the water removal rod is lower than that of the fogging rod. When the brush leaves the water surface, it first brushes over the water removal rod to scrape off the excess water on the brush bristles, and then passes over the fogging rod, making the water mist more delicate and facilitating the airflow to carry the water mist out.
[0013] Optionally, the rotating cylinder is provided with several partitions, which isolate the inner cavity of the rotating cylinder to form several isolation chambers, and the air outlets arranged in the same row along the axis of the rotating cylinder are connected to the same isolation chamber.
[0014] By adopting the above technical solution, the baffle makes the airflow evenly distributed in each isolation chamber, making the air outlet more uniform.
[0015] Optionally, the air intake mechanism includes an installation pipe fixed to the side wall of the water tank, the end of the rotating cylinder is rotatably connected to the end of the installation pipe through a sealed bearing, the end of the installation pipe facing away from the rotating cylinder is located outside the water tank, and a fresh air duct is connected to the installation pipe;
[0016] The air intake mechanism also includes an impeller, a central gear, a side gear, and an internal gear ring. An installation plate is provided inside the installation pipe. The impeller is rotatably connected to the installation plate. The central shaft of the impeller and the central shaft of the rotating cylinder are coaxially arranged. The central gear is coaxially fixed with the impeller. The side gear is rotatably arranged on the installation plate and meshes with the central gear. The internal gear ring is coaxially arranged on the inner wall of the rotating cylinder and meshes with the side gear.
[0017] By adopting the above technical solution, the rotation of the rotating cylinder drives the internal gear ring to rotate, which in turn causes the side gear ring and the central ring to rotate. This allows the impeller to rotate at a high speed while the airflow enters the rotating cylinder from the mounting cylinder, thus forming air supply.
[0018] Optionally, the installation pipe and the fresh air pipe are connected by a flange, and a fresh air filter is provided at the connection between the installation pipe and the fresh air pipe.
[0019] By adopting the above technical solution, the fresh air filter removes larger dust particles, reducing the difficulty of water washing and the frequency of water replacement in the water tank.
[0020] Optionally, the fresh air duct includes a first connecting pipe and a second connecting pipe that are interconnected, and the first connecting pipe and the second connecting pipe are respectively provided with an on / off valve.
[0021] By adopting the above technical solution, the first connecting pipe is connected to the outside and the second connecting pipe is connected to the inside. The opening and closing are controlled by the opening and closing valves respectively, so as to facilitate the selection of the air supply position. When selecting indoor air supply, the indoor air is washed with water, thereby improving the air quality; when selecting outdoor air supply, the freshness of the air is improved, thereby improving the air quality.
[0022] Secondly, the air conditioner provided in this application adopts the following technical solution:
[0023] An air conditioner that incorporates the aforementioned water-washing fresh air device.
[0024] By adopting the above technical solutions, air conditioners can easily wash and humidify the air, thereby improving the comfort of air conditioner use.
[0025] In summary, this application includes at least one of the following beneficial technical effects:
[0026] 1. Fresh air is divided into several small streams of airflow by the air outlet and emerges from underwater. The rotating cylinder rotates, causing the blades to rotate, which further disperses the small streams of airflow underwater, so that the airflow is thoroughly washed with water, improving the air washing effect and increasing the water mist carrying capacity.
[0027] 2. By setting up brush bristles and a water mist rod, the water mist formed is fine and easily carried by airflow, thereby increasing indoor humidity;
[0028] 3. By setting up baffles, the air output from the vents is made more uniform. Attached Figure Description

[0034] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0035] This application discloses a water-washing fresh air device. (Refer to...) Figure 1 , Figure 2 A water-washing fresh air device includes a water tank 1, an air intake mechanism 2, and a water washing mechanism 3. The air intake mechanism 2 drives fresh air into the water tank 1, and the water washing mechanism 3 washes the fresh air entering the water tank 1.
[0036] Reference Figure 2 , Figure 3 The water tank 1 has an air outlet 11 at its top. The air inlet mechanism 2 includes an installation pipe 21, an impeller 22, a central gear 23, a side gear 24, and an internal gear ring 25. The installation pipe 21 is fixed to the middle of the side wall of the water tank 1, with one end inside the water tank 1 and the other end extending outside. An installation plate 26 is fixed to the inner wall of the installation pipe 21, with both ends of the installation plate 26 fixed to the inner wall of the installation pipe 21. The impeller 22 is rotatably connected to the side of the installation plate 26 away from the inner cavity of the water tank 1. The central gear 23 is coaxially fixed to the impeller 22. The side gear 24 is rotatably connected to the side of the installation plate 26 away from the impeller 22, and the central gear 23 is coaxially fixed to the impeller 22. The side gear 24 is rotatably connected to the installation plate 26 and meshes with the central gear 23.
[0037] Reference Figure 3 , Figure 4The washing mechanism 3 includes a rotating drum 31 and a washing motor 32. The rotating drum 31 is rotatably connected to the end of the mounting pipe 21 facing the water tank 1 via a sealed bearing, thereby rotatably connecting the rotating drum 31 inside the water tank 1. The washing motor 32 is fixed to the side wall of the water tank 1 away from the mounting pipe 21. The motor shaft of the washing motor 32 is rotatably connected to the side wall of the water tank 1 via a sealed bearing. The motor shaft of the washing motor 32 and the rotating drum 31 are coaxially fixed, and the washing motor 32 drives the rotating drum 31 to rotate.
[0038] Reference Figure 3 , Figure 4 The axis of the rotating cylinder 31 is horizontal, and the axis of the impeller 22 coincides with the axis of the rotating cylinder 31. The central gear 23 and the side gear 24 are both located inside the end of the rotating cylinder 31 facing the mounting pipe 21. The internal gear ring 25 is coaxially fixed to the inner wall of the rotating cylinder 31, and the internal gear ring 25 meshes with the side gear 24. When the water washing motor 32 drives the rotating cylinder 31 to rotate, the impeller 22 also rotates, and the impeller 22 sends fresh air into the rotating cylinder 31.
[0039] Reference Figure 4 A fresh air duct 4 is connected to the end of the mounting pipe 21 away from the rotating cylinder 31 via a flange 5; a fresh air filter 6 is fixed at the connection between the mounting pipe 21 and the fresh air duct 4. Two opposing positioning blocks 211 are fixed on the inner wall of the mounting pipe 21, and the fresh air filter 6 abuts against the side of the positioning block 211 away from the water tank 1.
[0040] Reference Figure 4 The fresh air duct 4 includes a first connecting pipe 41 and a second connecting pipe 42 that are interconnected. Each of the first connecting pipe 41 and the second connecting pipe 42 is equipped with an on / off valve 7. The first connecting pipe 41 is used to connect to the outside, and the second connecting pipe 42 is used to connect to the inside.
[0041] Reference Figure 4 The washing mechanism 3 also includes several blades 33, which are evenly spaced along the circumference of the rotating cylinder 31. The length direction of the blades 33 extends along the radial direction of the rotating cylinder 31. The blades 33 are also evenly spaced along the length direction of the rotating cylinder 31. Several air outlets 311 are provided on the circumferential sidewall of the rotating cylinder 31, and the air outlets 311 are located between two adjacent blades 33 arranged circumferentially on the rotating cylinder 31.
[0042] Reference Figure 4All blades 33 have bristles 331 fixed at their ends away from the rotating cylinder 31, and the length direction of the bristles 331 on each blade 33 is the same as the length direction of the blade 33. At least one water mist rod 8 is fixed to the inner wall of the water tank 1. In this embodiment, five water mist rods 8 are fixed, and the length direction of the five water mist rods 8 is the same as the length direction of the rotating cylinder 31. The height of each water mist rod 8 is higher than the top of the rotating cylinder 31. When the rotating cylinder 31 rotates, each bristle 331 brushes past the five water mist rods 8 in sequence after leaving the water surface. The diameter of the bristles 331 is 0.2-0.5 mm; finer bristles 331 produce finer water mist.
[0043] Reference Figure 2 , Figure 4 The water mist rod 8 includes a water removal rod 81 and a misting rod 82. The water removal rod 81 is at a lower horizontal height than the misting rod 82. When the brush leaves the water surface, it first brushes over the water removal rod 81 to scrape off excess water from the bristles 331, and then passes over the misting rod 82 to make the water mist finer, making it easier for the airflow to carry the water mist out.
[0044] Reference Figure 3 , Figure 4 A partition 9 is provided inside the rotating cylinder 31, which isolates the inner cavity of the rotating cylinder 31 to form several isolation chambers 91. The length direction of the partition 9 is the same as the length direction of the rotating cylinder 31. The ends of the partition 9 in the width direction are fixed to each other, and the width direction of the other ends is evenly distributed in a direction away from the axis of the rotating cylinder 31. In this embodiment, six partitions 9 are provided, thereby forming six isolation chambers 91. The cross-section of the isolation chamber 91 is fan-shaped. The air outlets 311 arranged in the same row along the axis of the rotating cylinder 31 are connected to the same isolation chamber 91. This makes it easy for the airflow to be evenly distributed in each isolation chamber 91 and for the air outlets 311 to emit air evenly.
[0045] The implementation principle of the water-washing fresh air device in this application embodiment is as follows: When the water-washing fresh air device is in use, the water level in the water tank 1 is higher than that in the rotating cylinder 31. The water-washing motor 32 drives the rotating cylinder 31 to rotate. Through the internal gear ring 25, the side gear 24 and the central gear 23, the impeller 22 rotates, thereby sending indoor or outdoor air into the rotating cylinder 31 through the fresh air duct 4. At the same time, the fresh air is divided into several small airflows by the air outlet 311 and emerges from underwater. The rotation of the rotating cylinder 31 causes the blades 33 to rotate, thereby further dispersing the small airflows underwater, so that the airflow is fully washed, improving the water washing effect of the air. The airflow is divided into multiple small airflows, improving the water mist carrying capacity and increasing the indoor humidity.
[0046] This application also discloses an air conditioner that incorporates the aforementioned water-washing fresh air device. This allows the air conditioner to conveniently wash and humidify the air, improving the comfort of air conditioner use.
[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
