Description

Technical Field

[0001] This invention relates to the field of air treatment technology, and in particular to an air treatment module, an indoor air conditioning unit, and an air conditioner. Background Technology

[0002] As living standards gradually improve, air conditioners are becoming increasingly popular, and their functions are constantly being updated. Some air conditioner products on the market now include air handling functions such as humidification or sterilization. In related technologies, air conditioners are equipped with an air handling module, which includes a water collection tank and a wet membrane installed within the tank.

[0019] In one embodiment, the wet membrane is one in number, with the middle part of the wet membrane located above and covering the air vent, and the two ends of the wet membrane located in the two water absorption grooves respectively.

[0020] In one embodiment, the water receiving tank further includes an electrolytic cell, which is disposed between the water injection tank and the air outlet and between the two water absorption tanks, and the electrolytic cell connects the water injection tank and the water absorption tank; the air treatment module further includes an electrolysis device, which is disposed inside the electrolytic cell.

[0021] In one embodiment, the water injection tank has an outlet on one side along its length, the outlet is connected to the electrolytic cell through a bypass channel, the electrolytic cell is connected to a water suction tank away from the bypass channel, and a connecting channel is provided between the two water suction tanks.

[0023] In one embodiment, the wet film is arranged in a ring shape.

[0024] The present invention also proposes an indoor unit for an air conditioner, including a casing and an air handling module, wherein the air handling module is disposed within the casing, and the air handling module includes:

[0025] A water receiving trough, wherein an air vent is formed in the middle of the water receiving trough;

The air handling module has a good air handling effect; at the same time, as the wet membrane rotates, it can move into the water receiving tank and come into contact with the water in the tank, so that the wet membrane is wetted. Then the wet membrane is removed from the water receiving tank to block the air outlet. This ensures that the entire wet membrane can be wetted by the water in the water receiving tank, and also ensures that the moisture (especially the disinfectant water containing hypochlorous acid) in various parts of the wet membrane is evenly distributed, thereby further improving the air handling effect of the air handling module for humidification or sterilization; in addition, the air handling module has a simple structure, is easy to disassemble and assemble, and is convenient for maintenance or replacement.

When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0050] This invention proposes an air handling module. The humidification module can be used independently or as part of an indoor air conditioning unit; no specific limitation is made here.

[0051] Please see Figures 1 to 5 This invention proposes an air handling module 100, which includes a water receiving tank 110, a wet film assembly 150, and a driving device 160. An air outlet 113 is formed in the middle of the water receiving tank 110; the wet film assembly 150 includes a wet film support 152 and a wet film 151, the wet film 151 being sleeved on the wet film support 152 and rotatable relative to the wet film support 152, the lower end of the wet film 151 being located within the water receiving tank 110, and the wet film 151 at least partially covering the air outlet 113; the driving device 160 is used to drive the wet film 151 to rotate.

[0052] In this embodiment of the invention, an air passage 113 is formed in the middle of the water receiving tank 110 to facilitate airflow through the air passage 113. The shape of the air passage 113 can be various, such as square or approximately square, circular or approximately circular, elliptical or approximately elliptical, etc., without specific limitation. Because the air passage 113 is formed in the middle of the water receiving tank 110, the air passage area of ​​the air passage 113 is greatly increased, and the humidification area of ​​the wet film 151 is increased, thereby improving the air handling effect of the air handling module 100. The water receiving tank 110 has a first flange 111 and a second flange 112 facing each other. The air passage 113 is formed on the inner side of the first flange 111, and the second flange 112 is located on the outer periphery of the first flange 111. The height of the second flange 112 can be the same as the height of the first flange 111. Of course, for ease of assembly, the height of the second flange 112 can also be higher than the height of the first flange 111, without specific limitation.

[0053] As for the structure of the water receiving tank 110, there are various types. For example, in order to increase the air passing area of the air passing opening 113, thereby increasing the humidifying area of the wet film 151 and improving the humidifying efficiency and humidifying capacity, the water receiving tank 110 may include a water injection tank 120 and water absorption tanks 130 provided on both sides of the water injection tank 120. The water absorption tanks 130 are connected to the water injection tank 120, and the water injection tank 120 and the water absorption tanks 130 on both sides thereof enclose the air passing opening 113. Specifically, the water absorption tanks 130 are provided on opposite sides of the air passing opening 113. For a square air passing opening 113, the water absorption tanks 130 may be provided on opposite sides of the air passing opening 113 along its length direction, or may be provided on opposite sides of the air passing opening 113 along its width direction. It should be noted that there are various ways for the water injection tank 120 to be connected to the water absorption tanks 130. For example, both sides of the water injection tank 120 are respectively connected to the water absorption tanks 130 on both sides thereof, so that the water in the water injection tank 120 can flow into the two water absorption tanks 130 respectively. Another example is that one side of the water injection tank 120 is connected to one of the water absorption tanks 130, and the two water absorption tanks 130 are connected through a communication channel 131 (as shown in Figure 5 ), so that the water in the water injection tank 120 can flow into one of the water absorption tanks 130 and then flow into the other water absorption tank 130 through the communication channel 131.

[0054] In the embodiment of the present invention, the humidifying component includes a wet film support 152 and a wet film 151. Specifically, the wet film 151 is arranged in a substantially circular shape, and the wet film 151 is suitable for humidifying the air flow passing through it. The lower end of the wet film 151 is located in the water receiving tank 110, that is, the lower end of the wet film 15 is immersed in the water receiving tank 110. The wet film 151 is rotatable relative to the wet film support 152, so that one of the side of the wet film 151 facing the air passing opening 113 and the side facing away from the air passing opening 113 can move into the water receiving tank 110, and the other can move out of the water receiving tank 110. That is, during the rotation of the wet film 151, the wet film 151 can move into the water receiving tank 110 and contact the water in the water receiving tank 110, so that the wet film 151 is wetted, and then the wetted wet film 151 is moved out of the water receiving tank 110 to block above the air passing opening 113. This can ensure that the entire wet film 151 can be wetted by the water in the water receiving tank 110, and can also ensure that the moisture (especially the disinfectant water containing hypochlorous acid) in each part of the wet film 151 is distributed more evenly, thereby effectively improving the air treatment effect of humidifying or sterilizing and disinfecting of the air treatment module 100.

[0055] The wet membrane 151 at least partially covers the air vent 113, which can be understood as the wet membrane 151 covering part of the air vent 113, or the wet membrane 151 covering the entire air vent 113. For example, in one embodiment, the wet membrane 151 may have an upwardly convex arc-shaped structure, with the middle part of the wet membrane 151 located above and covering the air vent 113, and the two ends (lower ends) of the wet membrane 151 respectively located within the two water absorption grooves 130. In this embodiment, the wet membrane 151 may cover the entire air vent 113. As another example, in another embodiment, the lower end of the wet membrane 151 is located within the water absorption groove 130, and the wet membrane 151 is inclined upwards towards the air vent 113. In this embodiment, the wet membrane 151 is inclined, and the number of wet membranes 151 can be one, two, or more, without specific limitation. When there are two wet membranes 151, the two wet membranes 151 are located on opposite sides of the air outlet 113, with their lower ends located within the two water absorption grooves 130, and their upper ends inclined towards each other. It is worth noting that the upper ends of the two wet membranes 151 can abut against each other, thus covering the entire air outlet 113; alternatively, a gap can be left between the upper ends of the two wet membranes 151, allowing them to cover only a portion of the air outlet 113. No specific limitations are imposed here; selection and design can be based on actual usage needs.

[0056] In addition, in this embodiment of the invention, the driving device 160 is mainly used to drive the wet film 151 to rotate. The driving device 160 may include a motor or a cylinder, etc. There are many ways in which the driving device 160 drives the wet film 151 to rotate. For example, the driving device 160 drives the rotating shaft to rotate, thereby causing the wet film 151 to rotate; another example is that the driving device 160 drives the rotating shaft to rotate through a transmission assembly, thereby causing the wet film 151 to rotate. The transmission assembly may include a gear transmission assembly or a rack and pinion transmission assembly, etc. The driving method of the driving device 160 will be described in detail below, and will not be repeated here.

[0057] The air handling module 100 of the present invention includes a water receiving tank 110, a wet film assembly 150, and a driving device 160. An air outlet 113 is formed in the middle of the water receiving tank 110. The wet film assembly 150 includes a wet film support 152 and a wet film 151. The wet film support 152 is mounted on the water receiving tank 110, and the wet film 151 is sleeved on the wet film support 152 and rotatable relative to the wet film support 152. The lower end of the wet film 151 is located within the water receiving tank 110, and the wet film 151 at least partially covers the air outlet 113. The driving device 160 is used to drive the wet film 151 to rotate. Because the air outlet 113 is formed in the middle of the water receiving tank 110, the air passage area of ​​the air outlet 113 is greatly increased, thus increasing the size of the wet film 151. The humidification area of ​​the air handling module 100 is increased, thereby improving the air handling effect. Simultaneously, as the wet membrane 151 rotates, it moves into the water collection tank 110 and comes into contact with the water there, becoming wet. The wet membrane 151 is then removed from the water collection tank 110 to cover the air outlet 113. This ensures that the entire wet membrane 151 is moistened by the water in the water collection tank 110, and also ensures that the moisture (especially the disinfectant containing hypochlorous acid) is evenly distributed across all parts of the wet membrane 151, further improving the humidification or sterilization effect of the air handling module 100. Furthermore, the air handling module 100 has a simple structure, is easy to disassemble and assemble, and is convenient for maintenance or replacement.

[0058] Please see Figures 1 to 4 In one embodiment, there are two wet membranes 151, with the lower ends of the two wet membranes 151 located in the corresponding two water absorption grooves 130, and the upper ends of the two wet membranes 151 inclined towards each other.

[0059] Specifically, the wet membrane 151 is set at an angle to the bottom surface of the water absorption tank 130. Considering that the angle between the wet membrane 151 and the bottom surface of the water absorption tank 130 is greater than 60°, the area of ​​the air outlet 113 covered by the wet membrane 151 may be small, resulting in a smaller humidification area of ​​the wet membrane 151 and an increase in the overall height of the humidification module. On the other hand, if the angle between the wet membrane 151 and the bottom surface of the water absorption tank 130 is less than 30°, the width of the water absorption tank 130 may increase, thereby reducing the air passage area of ​​the air outlet 113 and resulting in a smaller humidification area of ​​the wet membrane 151. Therefore, in order to ensure that the air outlet 113 has a large air passage area and the wet film 151 has a large humidification area, while also reducing the overall height of the humidification module and reducing the installation space required to install the humidification module, the included angle between the wet film 151 and the bottom surface of the water absorption tank 130 can be greater than or equal to 30° and less than or equal to 60°.

[0060] Please see Figure 4 and Figure 6 In this embodiment, the wet film support 152 is installed on the water receiving tank 110. The two opposite ends of the wet film support 152 are respectively provided with a first rotating shaft 154 and a second rotating shaft 155. The wet film 151 is sleeved between the first rotating shaft 154 and the second rotating shaft 155. The driving device 160 drives and connects to the first rotating shaft 154.

[0061] Specifically, the first rotating shaft 154 and the second rotating shaft 155 are rotatable relative to the wet film support 152. The first rotating shaft 154 is the driving shaft, and the second rotating shaft 155 is the driven shaft. When the driving device 160 drives the first rotating shaft 154 to rotate, the rotation of the first rotating shaft 154 will drive the wet film 151 sleeved on the first rotating shaft 154 to rotate, and the rotation of the wet film 151 will also drive the second rotating shaft 155 to rotate. There are two possible positional relationships between the first rotating shaft 154 and the second rotating shaft 155. One is that the first rotating shaft 154 is located at the upper end of the wet film support 152, and the second rotating shaft 155 is located at the lower end of the wet film support 152; the other is that the first rotating shaft 154 is located at the lower end of the wet film support 152, and the second rotating shaft 155 is located at the upper end of the wet film support 152. No specific limitation is made here.

[0062] Please see Figure 1 , Figure 2 and Figure 6In this embodiment, the structure of the wet film support 152 can also be varied. For example, the wet film support 152 includes two mounting brackets 153 arranged opposite to each other. The two mounting brackets 153 are respectively located on both sides of the wet film 151. The two ends of the first rotating shaft 154 are rotatably connected to the two mounting brackets 153 respectively, and the two ends of the second rotating shaft 155 are rotatably connected to the two mounting brackets 153 respectively.

[0063] Considering that there are two wet membranes 151 in this embodiment, to facilitate the assembly of the wet membrane assembly 150, the two wet membranes 151 can be mounted on the same wet membrane support 152. For example, please refer to... Figure 2 The mounting bracket 153 includes a first mounting portion 1531 and a second mounting portion 1532 disposed at both ends of the first mounting portion 1531. The first mounting portion 1531 extends horizontally, and the second mounting portion 1532 is inclined from the first mounting portion 1531 toward the water absorption tank 130. The lower end of the second mounting portion 1532 is located inside the water absorption tank 130. The two ends of the first rotating shaft 154 are rotatably connected to the first mounting portions 1531 of the two mounting brackets 153 respectively, and the two ends of the second rotating shaft 155 are rotatably connected to the second mounting portions 1532 of the two mounting brackets 153 respectively.

[0064] Specifically, the first mounting part 1531 is provided with a first mounting hole for mounting the first rotating shaft 154, and the second mounting part 1532 is provided with a second mounting hole for mounting the second rotating shaft 155. There are two first mounting holes, located at opposite ends of the first mounting part 1531, and the second mounting hole is located at the lower end of the second mounting part 1532. The first mounting part 1531 and the second mounting part 1532 can be a mounting plate, a mounting groove 222, or a mounting block, etc., without specific limitations.

[0065] Optionally, please refer to Figure 7 To reduce the friction between the wet film 151 and the rotating shafts 154 and 155, and to facilitate the rotation of the wet film 151, a plurality of collars 158 can be provided on the first rotating shaft 154 and 155. These collars 158 are spaced apart along the axial direction of the first rotating shaft 154 and 155. This reduces the contact area between the wet film 151 and the first rotating shaft 154 and 155, thereby reducing the friction between the wet film 151 and the first rotating shaft 154 and 155, and facilitating the rotation of the wet film 151.

[0066] To further reduce the contact area between the wet film 151 and the first rotating shaft 154, a plurality of protrusions 159 can be provided on the peripheral wall of the collar 158 of the first rotating shaft 154, with the plurality of protrusions 159 distributed at intervals along the circumference of the collar 158. And / or, to further reduce the contact area between the wet film 151 and the second rotating shaft 155, a plurality of protrusions 159 can be provided on the peripheral wall of the collar 158 of the second rotating shaft 155, with the plurality of protrusions 159 distributed at intervals along the circumference of the collar 158. It should be noted that the protrusions 159 have a smooth surface that contacts the wet film 151.

[0067] Please see Figure 2 In this embodiment, the wet membrane support 152 further includes a connecting portion 1533, which is disposed between and connects the two mounting brackets 153. Thus, when the wet membrane assembly 150 needs to be removed, the wet membrane support 152 can be directly removed, improving the ease of assembly and disassembly of the wet membrane assembly 150.

[0068] Of course, in other embodiments, the two wet films 151 may be respectively mounted on the two wet film supports 152.

[0069] Please see Figure 2 , Figure 6 and Figure 7 In one embodiment, a first gear 156 is provided at one end of the first rotating shaft 154, and a second gear 163 meshing with the first gear 156 is provided on the drive shaft of the drive device 160. Thus, the drive device 160 can drive the first rotating shaft 154 to rotate via the gear set formed by the first gear 156 and the second gear 163, thereby driving the wet film 151 to rotate. Specifically, when the drive device 160 drives the second gear 163 to rotate, the second gear 163 meshes with the first gear 156, further driving the first gear 156 to rotate, thereby driving the first rotating shaft 154 to rotate, and the rotation of the first rotating shaft 154 will drive the wet film 151 to rotate.

[0070] It should be noted that the drive device 160 is mounted on the water receiving tank 110. To facilitate the disassembly of the drive device 160 and the wet film assembly 150, a linkage gear 157 can be provided on the wet film support 152 (e.g., Figure 6As shown, the linkage gear 157 meshes with the first gear 156, and the first gear 156 meshes with the linkage gear 157. This allows the drive device 160 and the second gear 163 located on the drive shaft of the drive device 160 to be directly disassembled for maintenance or replacement of the drive device 160. Optionally, the linkage gear 157 may be located above the first gear 156.

[0071] In this embodiment, the number of driving devices 160 can be one, in which case the driving device 160 simultaneously drives two first rotating shafts 154, meaning the driving device 160 can simultaneously drive two wet films 151 to rotate. Alternatively, the number of driving devices 160 can be two, in which case each driving device 160 drives one corresponding first rotating shaft 154, meaning each driving device 160 can drive one corresponding wet film 151 to rotate. Specifically, as... Figure 2 As shown, the drive device 160 includes a drive motor 161 and a motor mount 162 for mounting the drive motor 161, and the motor mount 162 is mounted on the water receiving tank 110.

[0072] Please see Figure 1 and Figure 3 In one embodiment, the drive device 160 is located on the side of the wet film 151 near the water injection tank 120, which makes the structure of the air handling module 100 more compact.

[0073] Please see Figure 4 Considering that there are two wet membranes 151, and a gap is formed between the two wet membranes 151, in order to prevent the airflow flowing upward from the air outlet 113 from flowing out through the gap, and to ensure that all the airflow flowing upward from the air outlet 113 passes through the wet membranes 151 and carries away the moisture on the wet membranes 151, so as to achieve better humidification and sterilization effects, optionally, a guide 180 is provided above the air outlet 113, and the guide 180 is used to guide the airflow to the wet membranes 151.

[0074] The structure of the air guide 180 can vary. For example, in one embodiment, the air guide 180 has a downwardly concave arc-shaped structure. In this embodiment, the air guide 180 serves two purposes: firstly, it guides the airflow, ensuring that all the airflow from the air outlet 113 flows upward toward the wet membrane 151, carrying away moisture from the wet membrane 151 as it passes through it, effectively improving humidification and sterilization; secondly, it catches water dripping from the upper end of the wet membrane 151, improving the safety of the air handling module 100.

[0075] For example, in another embodiment, the flow guide 180 is generally arranged in a "V" shape. Specifically, the flow guide 180 includes two flow guides, which are inclined from bottom to top in a direction away from each other, without being specifically limited here.

[0076] Based on the above embodiments, please refer to Figure 5 To enable the air handling module 100 to have a sterilization and disinfection function, removing bacteria, fungi, and other pathogens from the air, especially from object surfaces, the air handling module 100 may include an electrolysis device 170, which is located within the water receiving tank 110. The electrolysis device 170 can treat the liquid in the water receiving tank 110 into a substance with sterilization and disinfection effects, such as hypochlorous acid. When the wet membrane 151 absorbs the liquid in the water absorption tank 130, this sterilization and disinfection substance is adsorbed along with the liquid by the wet membrane 151. After the airflow passes through the wet membrane 151, it is not only humidified by the wet membrane 151 but also disinfected. Simultaneously, the sterilization and disinfection substance can be carried into the surfaces of objects in the room through the air for disinfection.

[0077] The specific installation location of the electrolysis unit 170 will be described in detail below.

[0078] Please see Figure 5 In one embodiment, the water receiving tank 110 further includes an electrolytic tank 140, which is located between the water injection tank 120 and the air outlet 113 and between the two water absorption tanks 130. The electrolytic tank 140 connects the water injection tank 120 and the water absorption tank 130. The electrolysis device 170 is located inside the electrolytic tank 140.

[0079] To prevent water in the water injection tank 120 from flowing directly into the water absorption tank 130 without being electrolyzed by the electrolysis device 170, in one embodiment, an outlet 121 can be provided on one side of the water injection tank 120 along its length. The outlet 121 is connected to the electrolysis tank 140 through a bypass channel 122. The electrolysis tank 140 is connected to a water absorption tank 130 away from the bypass channel 122, and a connecting channel 131 is provided between the two water absorption tanks 130.

[0080] In this embodiment, the connecting channel 131 and the electrolytic cell 140 are arranged opposite each other and are located on opposite sides of the air outlet 113. The electrolytic cell 140, the water absorption tank 130, and the connecting channel 131 together enclose the air outlet 113. In this way, the water in the water injection tank 120 first flows into the electrolytic cell 140 through the bypass channel 122, and generates disinfectant water containing hypochlorous acid under the electrolysis action of the electrolysis device 170. This disinfectant water then flows further into a water absorption tank 130 away from the bypass channel 122, and then flows into another water absorption tank 130 through the connecting channel 131, and is finally adsorbed by the wet film 151 located in the water absorption tank 130.

[0081] In another embodiment, an outlet 121 can be provided on the side of the water injection tank 120 near the electrolysis tank 140. The outlet 121 is directly connected to the electrolysis tank 140, and both sides of the electrolysis tank 140 are respectively connected to the two suction tanks 130. In this way, the water in the water injection tank 120 can flow directly into the electrolysis tank 140, and under the electrolysis action of the electrolysis device 170, a disinfectant containing hypochlorous acid is generated. This disinfectant flows from both sides of the electrolysis tank 140 into the suction tanks 130, and is finally adsorbed by the wet film 151 located in the suction tank 130.

[0082] Further, please refer to Figure 1 and Figure 2 The air handling module 100 also includes a cover plate 190, which covers the upper opening of the water injection tank 120. The cover plate 190 has a water injection port 191 for injecting water into the water injection tank 120. To prevent water from overflowing from the water injection tank 120, a sealing cap 192 can be provided at the water injection port 191.

[0083] Please see Figure 8 and Figure 9 The present invention also proposes an air conditioner indoor unit 200, which includes a housing 210 and an air handling module 100 disposed in the housing 210.

Without loss of generality, the housing 210 is provided with an indoor air inlet, an indoor air outlet, and a heat exchange duct connecting the indoor air inlet and the indoor air outlet. A heat exchanger and a fan are provided within the heat exchange duct.

[0085] In one embodiment, the housing 210 is further provided with a fresh air inlet and a fresh air outlet. The indoor unit 200 of the air conditioner also includes a fresh air module 220 disposed within the housing 210. The fresh air module 220 has a fresh air inlet, a fresh air outlet 221, and a fresh air duct connecting the fresh air inlet and the fresh air outlet 221. The fresh air inlet is connected to the fresh air inlet, and the fresh air outlet 221 is connected to the fresh air outlet, so that outdoor fresh air can flow in through the fresh air inlet, further flow into the fresh air duct, and finally flow out from the fresh air outlet.

[0086] To sterilize and disinfect fresh air, the air handling module 100 can be installed inside the fresh air duct. Furthermore, for ease of installation, a mounting slot 222 can be provided on the fresh air duct, allowing the air handling module 100 to be pulled out and installed within the slot 222, thus facilitating the installation, disassembly, and replacement of the air handling module 100.

[0087] The present invention also proposes an air conditioner, which includes an indoor unit 200 and an outdoor unit. The indoor unit 200 includes a housing 210 and an air handling module 100.
