For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] Based on the problem that the sub-unit of the existing air-conditioning equipment has a low air outlet speed and poor humidification effect as pointed out in the background technology, the utility model provides a sub-unit of an air-conditioning equipment and an air-conditioning equipment, which optimizes the humidification air duct inside the sub-unit, sets the water film as a tubular structure, thereby forming two humidification air ducts inside and outside the water film, so that the airflow can flow upward from the two humidification air ducts into the air supply cavity at the same time, thereby improving the humidification effect while ensuring the air flow and air outlet effect.

[0039] Specifically, Figures 1 to 6 As shown, the air conditioning device of the utility model includes a cabinet 1 and a sub-machine 2 that can be stored in the cabinet 1. The sub-machine 2 of the utility model includes: a base 21, the bottom of the base 21 has a walking mechanism; a shell 22, the shell 22 is installed on the base 21, and forms a receiving chamber with the base 21, a partition 23 is arranged in the receiving chamber, the partition 23 divides the receiving chamber into an air supply chamber 221 and a humidification chamber 222 vertically distributed from top to bottom, and a vent 231 connecting the air supply chamber 221 and the humidification chamber 222 is arranged on the partition 23; an air inlet 2221, the air inlet 2221 is arranged on the side of the humidification chamber 222, connecting the humidification chamber 222 with the external space; an air outlet 2211, the air outlet 2211 is arranged on the top of the air supply chamber 221, connecting the air supply chamber 221 with the external space; an air supply device 2 4. The air supply device 24 is installed in the air supply chamber 221, and can suck in air from the air inlet 2221 and discharge it from the air outlet 2211; the humidifying device, the humidifying device is installed in the humidifying chamber 222, and includes a water tank 251 and a water film 252 installed on the water tank 251, the bottom of the water film 252 is directly or indirectly in contact with the water in the water tank 251 to absorb moisture, the top of the water film 252 extends to the vent 231 and maintains a certain gap with the vent 231, the water film 252 is set to a tubular structure, and a first humidifying air duct 254 is formed between the outer wall of the water film 252 and the inner wall of the humidifying chamber 222, and the inner cavity of the water film 252 forms a second humidifying air duct 255, and air can pass through the water film 252 to flow upward in the first humidifying air duct 254 and the second humidifying air duct 255.

[0040] Exemplarily, the bottom of the cabinet 1 has a recovery chamber and a recovery port, and the recovery port connects the recovery chamber with the external space. The sub-machine 2 can enter the recovery chamber through the recovery port to be used in combination with the cabinet 1, or it can be separated from the cabinet 1 and run independently. Specifically, the bottom of the sub-machine 2 has a walking mechanism, and the walking mechanism can be flexibly set to a universal wheel, a ball bearing or a slider, etc. The utility model preferably installs a universal wheel at each of the four corners of the bottom of the sub-machine 2 to ensure the flexible movement of the sub-machine 2. When the sub-machine 2 needs to be separated from the cabinet 1, the user only needs to pull it out of the recovery chamber and flexibly push it to the room where it needs to be used. The power supply during operation is guaranteed by its own power supply or by connecting it to a nearby power supply, thereby overcoming the defect of a smaller air conditioning range of a traditional air-conditioning indoor unit due to its fixed position. When the sub-machine 2 is finished using, the sub-machine 2 only needs to be pushed into the recovery chamber. This arrangement can not only store the sub-machine 2 and save external space, but also perform maintenance work such as charging on the sub-machine 2 in the recovery chamber.

[0041] A door body is also provided at the recycling port, which can seal and shield the recycling chamber so as to protect the sub-machine 2 and make the cabinet 1 more tidy and beautiful.

[0042] The sub-machine 2 can be set with multiple functions as needed. In addition to the traditional temperature adjustment function, it can also be set to purify, humidify and sterilize the indoor air to meet the increasingly diverse usage needs of users.

[0043] The sub-machine 2 of the utility model can humidify, purify and sterilize the indoor air at the same time. The existing sub-machine 2 is installed with a water film 252 and a water tank 251. The water film 252 has certain water absorption and air permeability, can absorb moisture and allow air flow to pass through, and can humidify the air flow after absorbing water, thereby reducing the air humidity and achieving the purpose of humidification.

[0044] In actual applications, the specific shape and installation position of the water film 252 will affect the humidification effect of the airflow. For example, in order to further improve the humidification effect, many humidification devices seal the water film 252 in the air flow channel or on the air inlet and outlet 2211, so that the airflow must all pass through the water film 252 to ensure sufficient contact between the airflow and the water film 252. However, the disadvantage of this solution is that when the airflow passes through the water film 252, the gas flow rate will be significantly reduced due to the resistance of the water film 252, affecting the air supply efficiency. Therefore, it is necessary to increase the power and speed of the fan to compensate for the loss of flow rate, but this will increase the manufacturing cost.

[0045] In order to make the humidification effect and air supply efficiency of the sub-machine 2 meet the design requirements, a water film bracket 253 is arranged in the sub-machine 2 of the utility model. The water film bracket 253 is arranged as an annular frame structure. Due to the plasticity of the water film 252, the water film 252 can be fixed on the water film bracket 253 to form a tubular structure of the water film 252, and is installed on the water tank 251 in the vertical direction. The shape and size of the inner cavity of the water film 252 are adapted to the opening of the water tank 251. After the water is stored in the water tank 251, the bottom of the water film 252 can be in direct contact with the water surface, or it can be connected to the water tank 251 through a water absorption pipeline. As long as the water film 252 can absorb water, an annular air duct 2212 is formed between the outer wall of the water film 252 and the inner wall of the shell 22, that is, the first humidification The tubular inner cavity of the wet air duct 254 and the water film 252 forms a second humidification air duct 255. A certain gap is maintained between the top of the water film 252 and the vent 231, so that the first humidification air duct 254 and the second humidification air duct 255 are both connected with the vent 231. Under the action of the fan, the external air first enters the first humidification air duct 254 through the air inlet 2221. In the first humidification air duct 254, a part of the air directly goes up through the vent 231 into the air supply chamber 221, and the other part of the air passes through the water film 252 into the second humidification air duct 255, and goes up along the second humidification air duct 255 through the vent 231 into the air supply chamber 221. The two parts of air are mixed in the air supply chamber 221 and finally discharged through the air outlet 2211.

[0046] The airflow is humidified and supplied simultaneously through two humidification air ducts. On the one hand, the contact area between the airflow and the water film 252 is increased, so that the water film 252 can fully humidify the airflow and improve the humidification efficiency; on the other hand, a part of the air is made to flow directly upward into the air supply chamber 221 through the second humidification air duct 255 without passing through the water film 252, thereby avoiding the deceleration effect of the water film 252 on the air, which is beneficial to ensure the circulation speed of the air inside the sub-machine 2 and meet the requirements of the air supply volume. At the same time, there is no need to configure a higher-power motor to increase the air supply volume and control costs.

[0047] It should be noted that, in actual applications, those skilled in the art can flexibly set the type of water film 252, such as organic water film 252, inorganic glass fiber water film 252, aluminum alloy water film 252 or stainless steel water film 252, etc., as long as it can reduce the humidity of the airflow. Such flexible adjustments and changes do not deviate from the principle and scope of the present utility model and should be limited within the protection scope of the present utility model.

[0048] Preferably, if Figure 4 and Figure 5 As shown, the sub-unit 2 of the present invention further includes a purification device 26 installed in the air inlet 2221 .

[0049] Exemplarily, the purification device 26 is detachably installed on the inner side of the air inlet 2221, so that the sub-machine 2 has an air purification function, which can purify the external air entering the sub-machine 2, filter out various dust, bacteria, viruses and other foreign matter mixed in the air flow, and finally send clean air to the room through the air outlet 2211. At the same time, it avoids the influence of larger particles in the air on the operation of the equipment, which is beneficial to improve the service life of the equipment.

[0050] It should be noted that, in actual applications, those skilled in the art can flexibly set the type of purification device 26, such as a HEPA filter, an electrostatic electret filter or an activated carbon filter, etc., as long as it can improve the air purification effect. Such flexible adjustment and change does not deviate from the principle and scope of the present utility model and should be limited within the protection scope of the present utility model.

[0051] Preferably, if Figure 4 and Figure 5 As shown, the purification device 26 of the present invention is configured as a HEPA filter.

[0053] Preferably, if Figure 3 and Figure 5 As shown, the sub-unit 2 of the present invention further includes an air inlet grille, which is detachably mounted on the air inlet 2221 .

[0054] Through such an arrangement, on the one hand, the air inlet grille can protect the internal components at the air inlet 2221; on the other hand, through rapid disassembly and assembly, internal components such as the internal filter can be quickly replaced and maintained.
