Description

Technical Field

[0001] This utility model relates to the field of dehumidifier technology, and in particular to a low-noise dehumidifier. Background Technology

[0002] Most dehumidifiers on the market have rectangular evaporators and condensers. To accommodate these shapes, the air ducts in dehumidifiers are also mostly rectangular or designed in other irregular shapes. Current rectangular evaporators and condensers occupy a lot of space, requiring larger impellers and more powerful motors to match them. This results in greater vibration and noise during operation. Furthermore, rectangular or irregularly shaped air ducts encounter greater exhaust resistance and lower exhaust efficiency, which also contributes to the increased noise.

[0003] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a low-noise dehumidifier, which aims to solve the technical problem of high noise in existing dehumidifiers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A low-noise dehumidifier includes a frame and a circular air outlet duct, an arc-shaped condenser, an arc-shaped evaporator, and an arc-shaped air inlet plate disposed on the frame. The arc-shaped condenser, arc-shaped evaporator, and arc-shaped air inlet plate are arranged vertically and are positioned from the inside to the outside of the air inlet of the frame. The circular air outlet duct is disposed on the upper part of the frame, and a fan wheel and a drive motor are disposed on its top. A first partition plate is fixedly disposed below the circular air outlet duct. The first partition plate, the arc-shaped condenser, the arc-shaped evaporator, and the arc-shaped air inlet plate form an air duct.

[0007] In the aforementioned low-noise dehumidifier, the bottom surface of the circular air outlet duct is provided with two first limiting structures, and the tops of both ends of the arc-shaped condenser are respectively embedded in the two first limiting structures; the first limiting structures are used to restrict the displacement of the arc-shaped condenser.

[0008] In the aforementioned low-noise dehumidifier, the first limiting structure includes a first rear wall and a first outer wall; a first groove is provided on the first rear wall; a first heat exchange tube is provided on the arc-shaped condenser; and the exposed portion of the first heat exchange tube is inserted into the first groove.

[0009] In the aforementioned low-noise dehumidifier, a first connecting piece is provided on each of the two ends of the arc-shaped condenser, and a plurality of first fixing holes are provided on the first connecting piece; a plurality of second fixing holes are provided on the left and right ends of the first partition; the plurality of first fixing holes and second fixing holes are provided correspondingly; the first fixing holes and second fixing holes are used for fasteners to pass through, so that the arc-shaped condenser is fixedly connected to the first partition.

[0010] In the aforementioned low-noise dehumidifier, a first protrusion is provided on the outer side of the first connecting piece; a second protrusion is provided on the first outer side wall; the first protrusion is located inside the second protrusion and is used to restrict the arc-shaped condenser from moving outward.

[0011] In the aforementioned low-noise dehumidifier, a second limiting structure is provided on both sides of the bottom surface of the circular air outlet duct; the second limiting structure is located outside the first limiting structure and is engaged with the top of both ends of the arc-shaped evaporator to limit the displacement of the top of the arc-shaped evaporator.

[0012] The low-noise dehumidifier includes a support member inside the frame, and the arc-shaped condenser and arc-shaped evaporator are mounted on the support member; two third limiting structures are provided on the top surface of the support member; and the bottoms of both ends of the arc-shaped condenser are respectively embedded in the two third limiting structures.

[0013] In the aforementioned low-noise dehumidifier, the bottom of the first partition is fixedly connected to the top of the support member.

[0014] The low-noise dehumidifier is further provided with two fourth limiting structures on the top surface of the support member. The fourth limiting structures are located outside the third limiting structure and are used to limit the displacement of the bottom of the arc-shaped evaporator.

[0015] The low-noise dehumidifier includes a water collection trough on the top surface of the support member and a drain pipe at the bottom of the water collection trough; an arc-shaped evaporator positioned above the water collection trough; a water tank positioned below the water collection trough; the water tank being detachably connected to the frame; and the drain pipe being connected to the water tank.

Detailed Implementation

[0027] This utility model provides a low-noise dehumidifier. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0028] In the description of this utility model, it should be understood that the terms "upper," "lower," "left," and "right," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or a specific orientational structure and operation. Therefore, they should not be construed as limitations on this utility model. Furthermore, "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0029] Please see Figure 1 and Figure 2 This utility model provides a low-noise dehumidifier, including a frame 1 and a circular air outlet duct 2, an arc-shaped condenser 3, an arc-shaped evaporator 4, and an arc-shaped air inlet plate 5 disposed on the frame 1; the arc-shaped condenser 3, the arc-shaped evaporator 4, and the arc-shaped air inlet plate 5 are arranged vertically and are arranged from the inside to the outside on the air inlet of the frame 1; the circular air outlet duct 2 is disposed on the upper part of the frame 1, and a fan wheel 6 and a drive motor 9 are disposed on its top; a first partition 21 is fixedly disposed below the circular air outlet duct 2; the first partition 21, the arc-shaped condenser 3, the arc-shaped evaporator 4, and the arc-shaped air inlet plate 5 enclose and form an air duct.

[0030] Specifically, the arc-shaped air inlet plate 5 is detachably connected to the frame 1. The arc-shaped condenser 3 and arc-shaped evaporator 4 are vertically arranged and extend upwards to form an arc-shaped structure. Both ends of the arc-shaped condenser 3 are connected to the first partition plate 21, thereby forming an air duct, the bottom of which is closed. When the dehumidifier is running, air is drawn in from the side arc-shaped air inlet plate 5, and after passing through the arc-shaped evaporator 4 and arc-shaped condenser 3 in sequence, the air moves upwards and is discharged through the upper circular air outlet pipe 2. With the same volume, compared with the cuboid evaporator and condenser, the arc-shaped condenser 3 and arc-shaped evaporator 4 of this invention are narrower and directly participate in forming the air duct, which can effectively reduce the size of the air duct, thereby requiring a smaller impeller 6 and a lower power drive motor 9, reducing vibration and noise during dehumidifier operation.

[0031] Please see Figure 4 and Figure 5 In one embodiment, the bottom surface of the circular air outlet duct 2 is provided with two first limiting structures 22, and the tops of both ends of the arc-shaped condenser 3 are respectively embedded in the two first limiting structures 22; the first limiting structures 22 are used to restrict the displacement of the arc-shaped condenser 3. Specifically, the inner side and the left and right sides of the arc-shaped condenser 3 are all restricted by the first limiting structures 22.

[0032] Please see Figures 3-5 , Figure 8 and Figure 9 In one embodiment, the first limiting structure 22 includes a first rear wall 221 and a first outer wall 222; a first groove 223 is provided on the first rear wall 221; a first heat exchange tube 32 is provided on the arc-shaped condenser 3; the exposed portion of the first heat exchange tube 32 is inserted into the first groove 223. By further forming a snap-fit ​​structure, the connection between the arc-shaped condenser 3 and the circular air outlet duct 2 can be made tighter, reducing collisions between the various structures during vibration, thereby reducing noise.

[0033] Please see Figure 3 and Figure 4 In one embodiment, the two ends of the arc-shaped condenser 3 are respectively provided with first connecting pieces 31, and the first connecting pieces 31 are provided with a plurality of first fixing holes 312; the left and right ends of the first partition 21 are respectively provided with a plurality of second fixing holes 211; the plurality of first fixing holes 312 and second fixing holes 211 are correspondingly provided; the first fixing holes 312 and second fixing holes 211 are used for fasteners to pass through, so that the arc-shaped condenser 3 and the first partition 21 are fixedly connected. By further connecting the arc-shaped condenser 3 and the first partition 21, the various structures forming the air duct can be more tightly connected and formed as a whole. When the drive motor 9 causes vibration, the various structures will not collide due to loose connections.

[0034] Please see Figure 3 , Figure 5 , Figure 8 and Figure 9 In one embodiment, a first protrusion 311 is provided on the outer side of the first connecting piece 31; a second protrusion 224 is provided on the first outer side wall 222; the first protrusion 311 is located inside the second protrusion 224, and is used to restrict the arc-shaped condenser 3 from moving outward. When the top of the arc-shaped condenser 3 is inserted into the first limiting structure 22, the first protrusion 311 will also be stuck inside the second protrusion 224. Under the obstruction of the second protrusion 224, the first protrusion 311 cannot move outward, thereby preventing the arc-shaped condenser 3 from moving outward.

[0035] Please see Figure 5 and Figure 9In one embodiment, a second limiting structure 23 is respectively provided on both sides of the bottom surface of the circular air outlet pipe 2; the second limiting structure 23 is located outside the first limiting structure 22 and is engaged with the top of both ends of the arc-shaped evaporator 4 to limit the displacement of the top of the arc-shaped evaporator 4. Preferably, the second limiting structure 23 adopts the same structure as the first limiting structure 22; a second heat exchange tube 41 is provided on the arc-shaped evaporator 4; the exposed part of the second heat exchange tube 41 is engaged in the second limiting structure 23. The second limiting structure 23 also serves to limit the arc-shaped evaporator 4 from moving inward, outward, leftward, or rightward.

[0036] Please see Figure 6 In one embodiment, a support member 7 is provided inside the frame 1, and the arc-shaped condenser 3 and the arc-shaped evaporator 4 are disposed on the support member 7; two third limiting structures 73 are provided on the top surface of the support member 7; the bottoms of both ends of the arc-shaped condenser 3 are respectively embedded in the two third limiting structures 73.

[0037] Please see Figure 7 Preferably, the third limiting structure 73 includes a second rear wall 731; a second groove 733 is provided on the second rear wall 731; the exposed part of the second heat exchange tube 41 is inserted into the second groove 733. A third groove 734 is provided on the second outer side wall 732. The width of the first connecting piece 31 on the arc-shaped condenser 3 is greater than the thickness of the arc-shaped condenser 3, and its outer side protrudes from the arc-shaped condenser 3. The bottom of the first connecting piece 31 is inserted into the third groove 734, which restricts the outward movement of the arc-shaped condenser 3. By simultaneously and tightly fixing the top and bottom of the arc-shaped condenser 3, the overall structure can be more tightly connected and the noise during operation can be reduced. A second partition 71 is provided on the top of the support member 7. The second partition 71 closes the bottom of the air duct, so that air can only enter from the side arc-shaped air inlet plate 5. The arc-shaped condenser 3 and the arc-shaped evaporator 4 are disposed on the second partition 71.

[0038] Please see Figure 2 In one embodiment, the bottom of the first partition 21 is fixedly connected to the top of the support member 7, further strengthening the connection strength of each component structure.

[0039] Please see Figure 6In one embodiment, two fourth limiting structures 74 are further provided on the top surface of the support member 7. The fourth limiting structures 74 are located outside the third limiting structure 73 and are used to limit the displacement of the bottom of the arc-shaped evaporator 4. Preferably, a second connecting piece 42 is provided on each of the two ends of the arc-shaped evaporator 4, and the outer end of the second connecting piece 42 also protrudes from the arc-shaped evaporator 4. When the fourth limiting structure 74 adopts a structure mirroring the first limiting structure 22, the fourth limiting structure 74 can also engage with the protruding part of the second connecting piece 42 and form a block, thereby limiting the arc-shaped evaporator 4 from moving outward.

[0040] Please see Figure 6 In one embodiment, a water collection trough 75 is provided on the top surface of the support member 7, and a drain pipe is provided at the bottom of the water collection trough 75; the arc-shaped evaporator 4 is disposed above the water collection trough 75; a water tank 8 is disposed below the water collection trough 75; the water tank 8 is detachably connected to the frame 1; and the drain pipe communicates with the water tank 8. Specifically, the water collection trough 75 is disposed on the second partition 71. A support part 72 is also provided below the second partition 71 for supporting the second partition 71.

[0041] In summary, by setting up an arc-shaped condenser 3, an arc-shaped evaporator 4, and a first partition 21 to form an air duct, this invention can effectively reduce the actual volume of the air duct and the power requirement of the drive motor 9, thereby reducing the vibration and noise generated by the drive motor 9 during operation. Furthermore, the air duct structure formed by this invention and the circular air outlet duct 2 result in lower air resistance, which also helps to further reduce noise generation during exhaust.

[0042] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of this utility model, and all such substitutions or changes should fall within the protection scope of the appended claims of this utility model.
