Abstract
Description
Technical Field
[0001] This invention relates to the field of air conditioning technology, and more specifically, to a waterless humidifier with fresh air supply and an indoor unit and an air conditioner having the same. Background Technology
[0002] Most traditional wall-mounted air conditioners currently lack humidification functions, primarily because humidification requires manual water filling, which is inconvenient due to the high placement of the unit. In recent years, waterless humidifying air conditioners have emerged on the market. These typically employ an outdoor moisture-absorbing wheel device that transfers moisture absorbed outdoors to the indoor unit via pipes, thus controlling indoor humidity.
[0003] However, the above-mentioned waterless humidifiers still have significant drawbacks in actual use: 1) Due to the complex outdoor environment, the moisture-absorbing wheel device is difficult to protect when it is located outdoors, which will affect its service life and moisture absorption effect; 2) Since the moisture-absorbing wheel device is located outdoors, it is not easy to clean its filter or replace the moisture-absorbing wheel device. After a long period of use, the humidification effect of the air conditioner will be greatly affected. Summary of the Invention
[0004] In view of this, the technical problem to be solved by the present invention is: firstly, to provide a waterless humidifier with fresh air, so that the waterless humidifier can be installed indoors, eliminating the negative impact of the outdoor environment on the waterless humidifier, and at the same time enabling the waterless humidifier to have the dual functions of humidification and fresh air exchange.
[0005] To address the aforementioned technical problem in the first aspect, this invention proposes a waterless humidifier with fresh air intake, installed on the indoor unit of an air conditioner. The waterless humidifier includes, in sequence along the fresh air distribution direction, an outdoor fresh air inlet, an air duct distribution structure, an adsorption zone, and a desorption zone. A moisture-absorbing wheel is rotatably connected to both the adsorption zone and the desorption zone. The adsorption zone has a dehumidified air outlet, and the desorption zone has a moisture-absorbing air outlet. The dehumidified air outlet is connected to the outdoor side through an air outlet duct, and the moisture-absorbing air outlet is connected to the indoor side.
[0006] The waterless humidifier with fresh air as described in this invention allows the waterless humidifier to be installed indoors, eliminating the negative impact of the outdoor environment on the waterless humidifier, while also enabling the waterless humidifier to have the dual functions of humidification and fresh air exchange.
[0007] Preferably, the outdoor fresh air inlet is located inside the indoor unit and is connected to the outdoor side through an air guide structure.
[0008] When the waterless humidifier only has an indoor embedded part, the outdoor fresh air inlet is located inside the indoor unit and connected to the outdoor side through the air guide structure. This can further enhance the overall compactness of the waterless humidifier and make installation, cleaning and maintenance more convenient.
[0009] Preferably, the air duct diversion structure includes a volute air duct assembled from a right volute and a left volute, with a volute tongue disposed on the left volute. The left volute has an adsorption zone inlet leading to the adsorption zone at the rear end of the volute tongue, and a desorption zone inlet leading to the desorption zone is provided on the left end adjacent to the outer periphery of the volute tongue.
[0010] Under the influence of wind inertia, most of the fresh air will flow to the adsorption zone, which is conducive to the better performance of the adsorption zone. At the same time, the design of the volute air duct also helps to avoid the risk of backflow when fresh air enters the waterless humidifier.
[0011] Preferably, the waterless humidification device is equipped with a single fan in the volute air duct, and the single fan is a suction fan.
[0012] The combination of a single fan and a volute duct completely avoids the risk of backflow when fresh air enters the waterless humidifier. At the same time, the waterless humidifier only needs to have a single fan installed in the volute duct, which helps to further enhance the compactness of the overall structure of the waterless humidifier, making it easier to install the whole unit inside the indoor unit. It also helps to reduce the production and operating costs of the waterless humidifier.
[0013] Preferably, the waterless humidification device includes a moisture-absorbing rotor device located at the left end of the left volute. The moisture-absorbing rotor device is assembled from right to left as a right cover, the moisture-absorbing rotor, and a left cover. Two right partitions are arranged in the right cover, and two left partitions are arranged in the left cover. The right partitions cooperate with the left partitions to divide the moisture-absorbing rotor device into an adsorption zone and a desorption zone, wherein the volume of the adsorption zone is larger than the volume of the desorption zone.
[0014] As the desiccant rotates continuously, waterless humidification can be achieved. In addition, it helps to accumulate more sufficient air to be dehumidified in the adsorption zone, thereby further improving the waterless humidification effect of the desiccant device.
[0015] Preferably, the left volute and the right cover of the rotor are integrally formed.
[0016] It facilitates the rapid diversion of fresh air into the adsorption and desorption zones of the moisture-absorbing rotor device, improving the waterless humidification effect; at the same time, it saves material costs and makes the overall structure of the waterless humidification device more compact, making it easy to install the whole unit inside the indoor unit.
[0017] Preferably, a fresh air purification device is provided at the rear end of the outdoor fresh air inlet and at the right end of the air duct diversion structure, and the right volute is arranged close to the left end air outlet surface of the fresh air purification device.
[0018] Compared to other structures such as filters, fresh air purification devices have a better purification effect.
[0019] Preferably, the moisture-absorbing wheel is a moisture-absorbing material made of molecular sieve or silica gel, and an electric heating device is provided in the desorption zone.
[0020] Molecular sieves or silica gel have good hygroscopic properties, which can effectively adsorb moisture in the adsorption zone. They are also readily available and inexpensive. Meanwhile, electric heating devices have good heating and safety performance, and can play a good auxiliary heating role in the desorption zone to cooperate with the moisture-absorbing wheel for moisture release.
[0021] The technical problem to be solved by the present invention is that: in the second aspect, an indoor unit is provided, and / or in the third aspect, an air conditioner is provided, so that the waterless humidification device can be installed indoors, eliminating the negative impact of the outdoor environment on the waterless humidification device, and at the same time enabling the waterless humidification device to have the dual functions of humidification and fresh air exchange.
[0022] To solve the aforementioned technical problem in the second aspect, the present invention provides an indoor unit having a waterless humidification device with fresh air as described in any embodiment of the first aspect.
[0023] To solve the aforementioned third technical problem, the present invention provides an air conditioner having a waterless humidification device with fresh air as described in any embodiment of the first aspect.
[0024] Compared with the prior art, the waterless humidification device with fresh air and the indoor unit and air conditioner having it described in this invention have the following beneficial effects:
[0025] 1) This allows waterless humidifiers to be installed indoors, eliminating the negative impact of the outdoor environment on them;
[0026] 2) This enables the waterless humidifier to have the dual functions of humidification and fresh air exchange. Attached Figure Description

Detailed Implementation
[0037] To make the above-mentioned objectives, technical solutions, and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only some embodiments constituting the present invention, and are only used to explain the present invention and do not constitute a limitation thereof. Unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other.
[0038] Example 1
[0039] like Figure 1-7As shown, the present invention proposes a waterless humidification device with fresh air, which is installed on the indoor unit of an air conditioner. The waterless humidification device includes, in sequence along the fresh air distribution direction, an outdoor fresh air inlet 1, an air duct distribution structure 2, an adsorption zone 3, and a desorption zone 4. The adsorption zone 3 and the desorption zone 4 are rotatably connected to a moisture-absorbing wheel 62. The adsorption zone 3 has a dehumidified air outlet 31, and the desorption zone 4 has a moisture-absorbing air outlet 41. The dehumidified air outlet 31 is connected to the outdoor side through an air outlet duct, and the moisture-absorbing air outlet 41 is connected to the indoor side.
[0040] Specifically, after entering the waterless humidifier through the outdoor fresh air inlet 1, the outdoor fresh air is divided into the adsorption zone 3 and the desorption zone 4 by the air duct diversion structure 2. In the adsorption zone 3, the outdoor fresh air is dehumidified by the moisture absorption rotor 62 and then discharged to the outside through the dehumidified air outlet 31, which is connected to the outdoor side through an air outlet duct. In the desorption zone 4, the outdoor fresh air is dehumidified by the moisture absorption rotor 62 and then discharged to the room through the dehumidified air outlet 41.
[0041] Therefore, the waterless humidifier with fresh air as described in this invention allows the waterless humidifier to be installed indoors, eliminating the negative impact of the outdoor environment on the waterless humidifier, while also enabling the waterless humidifier to have the dual functions of humidification and fresh air exchange.
[0042] Preferably, the outdoor fresh air inlet 1 is located inside the indoor unit and is connected to the outdoor side through an air guide structure.
[0043] Specifically, although the waterless humidifier is installed entirely on the indoor unit of the air conditioner, this does not preclude it from including either an indoor recessed portion or an outdoor extended portion; of course, the waterless humidifier can also consist only of an indoor recessed portion. When the waterless humidifier includes an outdoor extended portion, the outdoor fresh air inlet 1 can be directly located on the outdoor side. In this case, the filter and other accessories can be located on the left end of the outdoor fresh air inlet 1, and thus still embedded in the indoor unit for easy cleaning and replacement later. In this invention, along the overall flow direction of the fresh air intake, the upstream direction of the fresh air intake, i.e., the direction closer to the outdoor side, is marked as the right end, and the downstream direction of the fresh air intake, i.e., the direction closer to the indoor side, is marked as the left end.
[0044] When the waterless humidifier only has an indoor embedded part, the outdoor fresh air inlet 1 is located inside the indoor unit and is connected to the outdoor side through the air guide structure. This can further enhance the overall compactness of the waterless humidifier and make installation, cleaning and maintenance more convenient.
[0045] As one example of the present invention, when the indoor unit is a wall-mounted unit, the installation position of the waterless humidifier is as follows: Figure 1As shown, the waterless humidifier is fully embedded inside the indoor unit and is located on one side of the indoor unit so as to be arranged side by side with the indoor unit air conditioning system.
[0046] Preferably, the air duct diversion structure 2 includes a volute air duct 21 assembled from a right volute 51 and a left volute 611, with a volute tongue 22 disposed on the left volute 611. The left volute 611 is provided with an adsorption zone inlet 32 leading to the adsorption zone 3 at the rear end of the volute tongue 22. The left volute 611 is adjacent to the outer periphery of the volute tongue 22 and is provided with a desorption zone inlet 42 leading to the desorption zone 4 along the left end.
[0047] Specifically, since the volute duct 21 is assembled from a right volute 51 and a left volute 611, outdoor fresh air enters the right volute 51 through the outdoor fresh air inlet 1. Its flow direction is changed within the volute duct 21, and it then flows along the volute duct 21 to the volute tongue 22, where it is split into the adsorption zone 3 and the desorption zone 4. Because the flow direction of the outdoor fresh air is changed within the volute duct 21, under the influence of wind inertia, most of the fresh air will obviously flow towards the adsorption zone 3, which is beneficial for the better adsorption effect of the adsorption zone 3. In this invention, the aforementioned "most of the fresh air" can also be referred to as "air to be dehumidified," and similarly, the small portion of fresh air flowing towards the desorption zone 4 can also be referred to as "air to be humidified." Furthermore, the volute duct 21 also helps to avoid the risk of backflow when fresh air enters the waterless humidification device.
[0048] Preferably, the waterless humidification device is equipped with a single fan 23 in the volute duct 21, and the single fan 23 is a suction fan.
[0049] Specifically, the single fan 23 is an extraction fan that can draw a large amount of fresh outdoor air into the waterless humidifier. The single fan 23 works in conjunction with the volute duct 21 to completely avoid the risk of backflow when fresh air enters the waterless humidifier. At the same time, under the continuous suction force of the extraction fan, the adsorption zone 3 will also be continuously supplied with air to be dehumidified. The dehumidified air is discharged to the outside through the dehumidified air outlet 31 and the air outlet duct with low backflow resistance. Therefore, the waterless humidifier only needs to be equipped with a single fan 23 in the volute duct 21. This helps to further enhance the compactness of the overall structure of the waterless humidifier, making it easy to install the whole unit inside the indoor unit. It also helps to reduce the production and operating costs of the waterless humidifier.
[0050] Preferably, the waterless humidification device includes a moisture-absorbing rotor device 6 located at the left end of the left volute 611. The moisture-absorbing rotor device 6 is assembled from right to left as a right rotor cover 61, a moisture-absorbing rotor 62, and a left rotor cover 63. Two right partitions 612 are arranged in the right rotor cover 61, and two left partitions 631 are arranged in the left rotor cover 63. The right partitions 612 and the left partitions 631 cooperate to divide the moisture-absorbing rotor device 6 into an adsorption zone 3 and a desorption zone 4, wherein the volume of the adsorption zone 3 is larger than the volume of the desorption zone 4.
[0051] Specifically, the moisture-absorbing wheel 62 is mounted in the center of the moisture-absorbing wheel device 6 and can be driven by the wheel drive motor 621 to rotate simultaneously in the adsorption zone 3 and the desorption zone 4 within the moisture-absorbing wheel device 6. In the adsorption zone 3, the moisture-absorbing wheel 62 continuously absorbs moisture from the air to be dehumidified; in the desorption zone 4, the moisture-absorbing wheel 62 releases the absorbed moisture, which is then absorbed by the air to be dehumidified and discharged into the room along with the dehumidified air. Thus, with the continuous rotation of the moisture-absorbing wheel 62, waterless humidification can be achieved continuously.
[0052] The moisture-absorbing rotor device 6 can usually be set up in a relatively sealed manner according to the disc-shaped space. At this time, both the adsorption zone 3 and the desorption zone 4 will be arranged in a fan shape. The central angle of the fan shape of the adsorption zone 3 will be larger than that of the fan shape of the desorption zone 4, which is conducive to accumulating more sufficient air to be dehumidified in the adsorption zone 3, thereby further improving the waterless humidification effect of the moisture-absorbing rotor device 6.
[0053] Preferably, the left volute 611 and the right cover 61 of the rotor are integrally formed.
[0054] Specifically, the right side of the integrally molded device is the left volute 611, and the left side is the right cover of the rotor 61. Furthermore, the adsorption zone inlet 32 and the desorption zone inlet 42 will be directly opened on the right cover of the rotor 61 without the need for a connection through intermediate accessories. This facilitates the rapid diversion of fresh air into the adsorption zone 3 and desorption zone 4 of the moisture-absorbing rotor device 6, improving the waterless humidification effect. At the same time, it also saves material costs and makes the overall structure of the waterless humidification device more compact, making it easier to install the whole device into the indoor unit.
[0055] Preferably, the moisture-absorbing wheel 62 is a moisture-absorbing material made of molecular sieve or silica gel, and an electric heating device 43 is provided in the desorption zone 4.
[0056] Specifically, molecular sieves or silica gel have good hygroscopic properties, which can effectively adsorb moisture in adsorption zone 3, and they are readily available and inexpensive. The electric heating device 43 also has good heating and safety performance, and can effectively provide auxiliary heating in desorption zone 4 to cooperate with the moisture-absorbing rotor 62 in releasing moisture. Of course, this invention does not specifically limit the materials used to prepare the moisture-absorbing rotor 62 or the specific arrangement of the heating device in desorption zone 4. Those skilled in the art will understand that the moisture-absorbing rotor 62 can be made of other hygroscopic materials, and other types of heating devices can be provided in desorption zone 4, all according to actual needs.
[0057] Preferably, a fresh air purification device 5 is provided at the rear end of the outdoor fresh air inlet 1 and at the right end of the air duct diversion structure 2, and the right volute 51 is arranged close to the left end air outlet surface of the fresh air purification device 5.
[0058] Specifically, when outdoor fresh air enters the waterless humidifier through the outdoor fresh air inlet 1, it is first purified by the fresh air purification device 5. Compared with other structures such as filters, the fresh air purification device 5 has a better purification effect. As one example of the present invention, the fresh air purification device 5 can be configured as an insert type with an insert housing. In this case, the right volute 51 is set close to the left end air outlet surface of the insert housing to facilitate the later maintenance of the fresh air purification device. As another example of the present invention, the right volute 51 can also be integrally formed with the left end air outlet surface of the fresh air purification device 5 or the left end air outlet surface of the insert housing.
[0059] Finally, it should be noted that the waterless humidifier with fresh air described in this invention is not limited to installation on the indoor unit of a wall-mounted air conditioner. Those skilled in the art will understand that the overall appearance and structure of the waterless humidifier with fresh air described in this invention has great plasticity, and it can also be adapted to be installed on the indoor unit of most floor-standing air conditioners.

[0062] The present invention also provides an air conditioner having the waterless humidification device with fresh air as described in Embodiment 1.
[0063] Specifically, those skilled in the art will understand that when the indoor unit and / or air conditioner provided in Embodiment 2 have the waterless humidification device with fresh air as described in Embodiment 1, the solution to the corresponding technical problem and the achievement of the technical effect can be found in the description of the waterless humidification device with fresh air in Embodiment 1, and will not be repeated here.
[0064] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
