Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to a waterless humidification module and an air conditioner. Background Art

[0002] Waterless humidification modules are primarily used in air conditioners. Their primary function is to humidify incoming indoor air without the need for additional water, reducing the humidification module's structure, the overall size of the air conditioner, and its manufacturing cost. Typically, an adsorption material is placed on an adsorption rotor. One portion of the rotor acts as an adsorption material, absorbing moisture from the air and discharging the adsorbed air outdoors. Another portion of the rotor acts as a desorption material. Air from a fan is heated by a heater before entering the adsorption rotor. Once inside, the hot air absorbs moisture from the adsorption material, achieving humidification and discharging the humidified air into the room. The air from the fan, heated by the heater, exerts a certain amount of resistance on the heater. If the heater is not securely fixed, it can easily become detached. Therefore, improved heater securing is needed. Currently, most existing technologies use relatively complex structures to secure the heater, making installation complex and difficult to maintain.

DETAILED DESCRIPTION

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0025] First embodiment

[0026] See also Figure 1 and Figure 2 This embodiment provides a waterless humidification module 100. The waterless humidification module 100 provided in this embodiment fixes the heater 140 through the outer frame 150, has a simple structure, is more convenient to install, and is easy to maintain.

[0027] The waterless humidification module 100 is used in the air conditioner 10, primarily for humidifying incoming indoor air without the need for additional water. This reduces the size of the humidification module, the overall size of the air conditioner 10, and the manufacturing cost. Generally, an adsorption material is placed on the adsorption rotor 110. A portion of the adsorption rotor 110 acts as an adsorbent, absorbing moisture from the air and discharging the adsorbed air outdoors. Another portion of the adsorption rotor 110 acts as a desorption agent. Air blown from the fan 130 is heated by the heater 140 before entering the adsorption rotor 110. Once inside the rotor, the hot air absorbs moisture from the adsorption material, achieving humidification. The humidified air is then discharged into the room. When the fan 130 is heated by the heater 140, it exerts a certain amount of resistance on the heater 140. If the heater 140 is not firmly fixed, it is easy for it to become detached. Therefore, it is necessary to improve the fixing effect of the heater 140. Currently, most existing technologies use relatively complex structures to fix the heater 140, resulting in complex installation and difficult maintenance. The waterless humidification module 100 provided in this embodiment fixes the heater 140 through the outer frame 150, which has a simple structure, is more convenient for installation, and is easy to maintain.

[0028] In this embodiment, the waterless humidification module 100 includes: an adsorption wheel 110, a wheel lower cover 120, a fan 130, a heater 140, an outer frame 150, a fixing member 156 and a snap-fit ​​member 160. The adsorption wheel 110 is mounted on the wheel lower cover 120, the fan 130 is mounted on the side of the adsorption wheel 110 away from the wheel lower cover 120, the heater 140 is mounted on the outer frame 150, the heater 140 and the outer frame 150 are arranged between the fan 130 and the adsorption wheel 110, and are used to heat part of the air blown out by the fan 130. The snap-fit ​​member 160 is mounted on the outer frame 150, the snap-fit ​​member 160 cooperates with the wheel lower cover 120, and the fixing member 156 is fixedly connected to the outer frame 150 and the wheel lower cover 120.

[0029] In this embodiment, the fastener 160 is set on the outer frame 150. When installing the outer frame 150, the fastener 160 is first matched with the lower plate of the rotating wheel to position the outer frame 150 first, and then the outer frame 150 and the lower plate of the rotating wheel are fixed by the fixing member 156. The structure is simple, the installation is convenient, and the maintenance is convenient.

[0030] In this embodiment, when the waterless humidification module 100 is in operation, the fan 130 is positioned above the heater 140, while the adsorption rotor 110 and its lower rotor cover 120 are positioned below the heater 140. A portion of the air blown by the fan 130 passes directly through the adsorption rotor 110. The adsorption material on the adsorption rotor 110 absorbs moisture from the air, and the treated air is then discharged outdoors. The remaining air, heated by the heater 140, passes through the adsorption rotor 110, which contains the adsorption material. The heated air then desorbs moisture from the adsorption material, thereby humidifying the air. The humidified air then enters the room, humidifying the indoor air.

[0031] In this embodiment, the heater 140 needs to quickly make the air reach a higher temperature, so the temperature of the heater 140 is relatively high, and the outer frame 150 is mainly used to fix the heater 140, so the outer frame 150 needs to be resistant to high temperatures. The outer frame 150 is made of high-temperature resistant materials, specifically, nylon materials or PPC materials. That is to say, the outer frame 150 is a nylon outer frame 150 or a PPC outer frame 150. Nylon materials and PPC materials can work at high temperatures for a long time, are firm and reliable, have little deformation, and have good heat dissipation. The overall surface temperature of the outer frame 150 can reach more than 300 degrees, far exceeding the surface limit temperature of the heater 140 of 250 degrees.

[0032] Among them, PPC material refers to polymethyl ethylene carbonate.

[0033] At the same time, the outer frame 150 is a PPC outer frame 150 or a nylon outer frame 150, which avoids direct contact between metal and the heater 140, has good insulation and high electrical safety, and can be promoted on a large scale.

[0034] See also Figure 3 and Figure 4 In this embodiment, the fastener 160 includes a fixing section 162 and a stop section 164 , one end of the fixing section 162 is connected to the outer frame 150 , and the other end of the fixing section 162 is connected to the stop section 164 , and the stop section 164 cooperates with the lower cover 120 of the rotor.

[0035] In this embodiment, the fixing section 162 connects the outer frame 150 and the stop section 164 so that the outer frame 150 and the stop section 164 are spaced apart. The stop section 164 extends into the structure of the rotor lower cover 120 and is clamped in the rotor lower cover 120 .

[0036] Similarly, an avoidance groove 170 is provided on the main body 154, and a protrusion is provided on the wheel lower cover 120. The avoidance groove 170 cooperates with the protrusion to realize the positioning of the main body 154, and the outer frame 150 is fixed to the wheel lower cover 120 through the fastener 160 on the main body 154.

[0037] In this embodiment, a first fixing hole 152 is provided on the outer frame 150 , a second fixing hole is provided on the rotor lower cover 120 , and the fixing member 156 cooperates with the first fixing hole 152 and the second fixing hole.

[0038] The fixing member 156 is a fastening screw. After the latch 160 engages with the lower rotor cover 120, the fixing member 156 extends into the first fixing hole 152 and the second fixing hole, thereby securing the outer frame 150 to the lower rotor cover 120. Fastening the screws secures the outer frame 150 to the lower rotor cover 120, enabling modular installation and facilitating after-sales maintenance.

[0039] In this embodiment, the outer frame 150 includes a body 154 and a fixing member 156 . The fixing member 156 is mounted on the body 154 . The fixing member 156 is a hollow structure and is used to fix the heater 140 .

[0040] In this embodiment, the fixing member 156 is a hollow structure for installing the heater 140. The hollow fixing member 156 enables the air blown out by the fan 130 to pass through the heater 140 and flow to the adsorption wheel 110 with adsorption material, desorbing the moisture attached to the adsorption material, thereby achieving the purpose of humidification.

[0041] In this embodiment, the fixing member 156 includes multiple fixing plates 157 and multiple clamping portions 158. The multiple fixing plates 157 are installed on the main body 154 to form a fixing cavity 159. The heater 140 is installed in the fixing cavity 159. The multiple clamping portions 158 are respectively installed on the multiple fixing plates 157.

[0042] In this embodiment, multiple fixing plates 157 form a fixing cavity 159. During the installation of the heater 140, the heater 140 first slides relative to the holding portion 158. After sliding into place, the holding portion 158 holds the heater 140 in the fixing cavity 159.

[0043] For ease of description, the end of the fixing cavity 159 closest to the retaining portion 158 is defined as the top, and the end away from the retaining portion 158 is defined as the bottom. The fixing member 156 has a hollow structure, meaning that the fixing cavity 159 is a mid-frame structure. The opening at the bottom of the fixing cavity 159 is smaller than the outer dimensions of the heater 140. The bottom of the fixing cavity 159 restrains the heater 140 in the direction away from the retaining portion 158, while the retaining portion 158 restrains the heater 140 in the direction toward the retaining portion 158, thereby securing the heater 140 within the fixing cavity 159.

[0044] In this embodiment, the projection of the heater 140 at the bottom of the fixed cavity 159 is a rectangle, and the opening at the bottom of the fixed cavity 159 is also a rectangle. The width of the bottom opening is smaller than the width of the heater 140, and the length of the bottom opening is smaller than the length of the heater 140. This means that the outer dimensions of the bottom opening are smaller than the outer dimensions of the heater 140, thereby ensuring that the heater 140 will not fall out of the opening.

[0045] In this embodiment, there are multiple clamping parts 158, and the multiple clamping parts 158 are arranged at intervals on multiple fixed plates 157. When the heater 140 is installed in the fixed cavity 159, the multiple clamping parts 158 clamp the heater 140 from all sides, thereby fixing the heater 140 at the top of the fixed cavity 159.

[0046] See also Figure 5 In this embodiment, the holding portion 158 includes a connecting section 1582 and a guide section 1584. One end of the connecting section 1582 is connected to the fixed plate 157, and the other end is connected to the guide section 1584. The heater 140 can slide relative to the guide section 1584. When the heater 140 and the guide section 1584 are out of sliding, the heater 140 is clamped into the fixed cavity 159.

[0047] Among them, the connecting section 1582 is mainly used to connect the fixing plate 157 and the guide section 1584. During the installation of the heater 140, the heater 140 gradually slides from the guide section 1584 away from the connecting section 1582 to one end close to the connecting section 1582 relative to the guide section 1584. When the heater 140 and the guide section 1584 are out of sliding, the heater 140 is clamped between the bottom of the fixing cavity 159 and the clamping section, thereby fixing the heater 140.

[0048] In this embodiment, the guide section 1584 includes a guide surface 1586 and a stop surface 1588. The guide surface 1586 is arranged obliquely relative to the connecting section 1582, and the stop surface 1588 is provided below the guide section 1584 and connected to the connecting section 1582. During installation of the heater 140, the heater 140 first abuts against the guide surface 1586 and slides relative to the guide surface 1586. When the heater 140 and the guide surface 1586 are disengaged from each other, the heater 140 is inserted between the guide section 1584 and the bottom of the fixing cavity 159, abutting against the stop surface 1588 of the guide section 1584, thereby securing the heater 140.

[0049] It is easy to understand that the guide section 1584 is protruded on the connecting section 1582, and the stop surface 1588 is set on the part of the guide section 1584 that protrudes relative to the connecting section 1582. When the heater 140 is fixed in the fixed cavity 159, the stop surface 1588 limits the heater 140 in the top direction of the fixed cavity 159.

[0050] It should be noted that, in addition to the scheme in which the guide segment 1584 protrudes from the connecting segment 1582, the guide segment 1584 can also be flush with the connecting segment 1582. That is, the guide segment 1584 does not have the stop surface 1588, but only has the guide surface 1586. The guide segment 1584 can only serve as a guide and cannot limit the position of the heater 140. Because the guide segment 1584 with only the guide surface 1586 does not have a limiting function, the number of guide segments 1584 with only the guide surface 1586 is relatively small.

[0051] In this embodiment, there are multiple fixed cavities 159 and multiple heaters 140 , and the multiple heaters 140 are arranged along the radial direction of the adsorption wheel 110 .

[0052] In this embodiment, there are multiple heaters 140, and the multiple heaters 140 are arranged along the radial direction of the adsorption wheel 110. The heating area can cover the entire fan-shaped desorption area of ​​the wheel. The larger the heating area of ​​the air blown out by the fan 130, the better the desorption effect of the moisture attached to the adsorption material, the larger the utilization area of ​​the adsorption wheel 110, and the humidification efficiency of the adsorption wheel 110 is improved.

[0053] Preferably, in this embodiment, there are two heaters 140 and two fixed cavities 159 . The two heaters 140 are respectively disposed in the two fixed cavities 159 , and the two heaters 140 are disposed side by side in the radial direction of the adsorption wheel 110 .

[0054] In this embodiment, the plurality of heaters 140 are at least partially staggered.

[0055] In this embodiment, the partial staggered arrangement of the multiple heaters 140 can increase the heating area of ​​the air blown out by the fan 130. The larger the heating area of ​​the air blown out by the fan 130, the better the desorption effect of the moisture attached to the adsorption material, the larger the utilization area of ​​the adsorption wheel 110, and the improved humidification efficiency of the adsorption wheel 110.

[0056] In this embodiment, two adjacent fixed cavities 159 are connected, and the gap between two adjacent heaters 140 prevents part of the air from flowing out of the two adjacent heaters 140 without being heated, thereby increasing the heating area of ​​the air blown out by the fan 130.

[0057] In this embodiment, the waterless humidification module 100 further includes a reinforcing rib 180 , one end of which is connected to the body 154 , and the other end is connected to the fixing plate 157 , mainly used to enhance the strength of the fixing plate 157 and improve the fixing effect of the fixing plate 157 on the heater 140 .

[0058] Similarly, there are multiple reinforcing ribs 180 , and one fixing plate 157 is connected to the main body 154 via at least one reinforcing rib 180 .

[0059] Under the premise of meeting the strength requirement, the height of the surface of the reinforcing rib 180 is lower than the upper surface height of the heater 140, which is conducive to the cold air passing through the heater 140 from bottom to top and diffusing on the main body of the adsorption wheel 110, thereby increasing the effective desorption area of ​​the adsorption wheel 110.

[0060] In this embodiment, a wire groove 190 is further provided on the main body 154 . The wire groove 190 is used for allowing the connecting wires of the heater 140 to pass through, thereby facilitating the wiring of the heater 140 .

[0061] To sum up, the waterless humidification module 100 provided in this embodiment, in this embodiment, the fastener 160 is set on the outer frame 150. When installing the outer frame 150, the fastener 160 is first matched with the lower plate of the rotor, the outer frame 150 is first positioned, and then the outer frame 150 and the lower plate of the rotor are fixed by the fixing member 156. The structure is simple, the installation is convenient, and the maintenance is convenient.
