Description

Technical Field

[0001] This utility model relates to the field of household appliance sealing device technology, specifically a fan cover assembly and a clothes dryer. Background Technology

[0002] A sealing device, including a fan cover and an air vent, is installed on the rear cover of the dryer to reduce vibration and noise during use. The fan cover uses sponge strips to form the first seal against the rear cover, followed by a sound insulation panel and the air vent to form the second seal. This sequential arrangement of the fan cover, sound insulation panel, and air vent creates two layers of seal for the rear of the dryer, resulting in a complex structure and low modularity, which is detrimental to production. Furthermore, the increasing area of ​​the fan cover, sound insulation panel, and air vent leads to higher material and labor costs. Additionally, the two layers of seal increase the distance between the rear cover and the rear of the dryer, increasing its footprint and making it inconvenient to integrate with home décor. Utility Model Content

[0003] To address the above problems, this utility model provides a fan cover assembly and a clothes dryer, which can at least solve some of the problems in the prior art.

[0004] The first aspect of this utility model provides a fan cover assembly suitable for a clothes dryer, comprising: an isolation plate, which is disposed facing the fan of the clothes dryer; a fan cover, wherein the shape of the isolation plate matches the fan cover, the fan cover is fastened to the isolation plate in the direction facing the isolation plate, and a sound insulation cavity is formed between the fan cover and the isolation plate; and a soundproofing material located inside the sound insulation cavity.

[0005] By using the above methods, a sealed soundproof cavity is formed by setting up an isolation plate and a fan cover. Sound-absorbing material is then placed inside this cavity to improve sound insulation and reduce vibration and noise. Since the fan cover is the outermost component, the area of ​​the isolation plate and sound-absorbing material is less than or equal to the area of ​​the fan cover, reducing their overall size and material costs. The shape of the isolation plate matches the shape of the fan cover, simplifying the structure, reducing mold manufacturing costs, and facilitating production. The reduced distance between the rear of the dryer and its outermost edge minimizes its footprint, meeting the requirements for an ultra-thin design and allowing for seamless integration with other home décor styles.

[0006] Optionally, a first sponge strip and a second sponge strip are provided on the side of the fan cover facing the dryer, with the first sponge strip tightly connected to the inner circumference of the fan cover. This ensures a tight seal between the dryer and the fan cover.

[0007] Optionally, the fan cover is provided with isolation ribs, and the second sponge strip is connected to the end of the isolation ribs in a close-fitting manner. In this way, the isolation ribs isolate the roller bearings of the dryer, and the second sponge strip is provided at the isolation ribs to further prevent dust in the air duct from adhering to the roller bearings.

[0008] Optionally, the shape of the sound-absorbing material can be matched to the fan cover. These methods further enhance the sound insulation effect.

[0009] Optionally, multiple sound-damping materials can be used. Through the above method, multiple sound-damping materials are combined into a shape that matches the fan cover, refining the components, facilitating assembly, and allowing for the replacement of specific sections of the sound-damping materials. This prevents excessive localized vibration that could reduce the sound-damping effect, saves materials, and allows for precise replacement.

[0010] Optionally, the dryer includes a rear cover, with the end of the fan shroud facing the dryer abutting against the rear cover. This method achieves a rear-side seal for the dryer via the fan shroud.

[0011] Optionally, the isolation plate and the fan cover are connected by screws. This method facilitates the assembly and disassembly of the isolation plate and the fan cover.

[0012] A second aspect of this invention provides a clothes dryer having the aforementioned fan cover assembly. This enables a rear-side seal for the clothes dryer.

[0013] Optionally, the dryer includes a rear cover and a fan that are adjacent to each other, with the fan shroud assembly fastened to the rear cover. In this way, the fan shroud assembly can achieve a seal on the rear side of the dryer through the rear cover, while also reducing vibration and noise when the fan is in use or the dryer is operating.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] <Fan shroud assembly 100>

[0023] Figure 1 This is a schematic diagram of the structure of the fan cover assembly 100 in the embodiment of this utility model. Figure 2 This is a first structural schematic diagram of the dryer 200 in this embodiment of the present utility model. Figure 3 for Figure 2 A magnified view of point A in the middle. Combined with... Figure 1 and refer to Figure 2 and Figure 3 This utility model provides a fan cover assembly 100 suitable for a clothes dryer 200. The fan cover assembly 100 includes a partition plate 110, a sound-absorbing material 120, and a fan cover 130 arranged sequentially. The lower half of the partition plate 110 is in close contact with the fan (e.g., the one at the rear of the clothes dryer 200) on the back. Figure 3 The fan 220 shown is positioned opposite to the isolation plate 110. The fan cover 130 is fastened to the isolation plate 110 in the direction facing it, forming a soundproof cavity 140. The isolation plate 110 separates the fan 220 of the dryer 200 from the fan cover 130, providing a buffering effect. The shape of the isolation plate 110 matches the fan cover 130 to ensure the airtightness of the soundproof cavity 140. Sound-absorbing material 120 is located within the soundproof cavity 140, which can reduce and weaken noise.

[0024] Through the above methods, the mutually matched isolation plate 110 and fan cover 130 form a sealed soundproof cavity 140, achieving a seal on the rear side of the dryer 200. Sound-absorbing material 120 is placed inside the soundproof cavity 140 to improve sound insulation and reduce vibration and noise from the fan 220. Since the fan cover 130 is the outermost component, the area of ​​the isolation plate 110 and the sound-absorbing material 120 is less than or equal to the area of ​​the fan cover 130. Compared to the prior art where the sound-absorbing material 120 and the air supply cover are both located on the outer side of the fan cover 130 and their areas are larger than the fan cover 130, this embodiment reduces the area of ​​the isolation plate 110 and the sound-absorbing material 120, and also reduces the material cost of the air supply cover. The shape of the isolation plate 110 matches the shape of the fan cover 130, ensuring the airtightness of the soundproof cavity 140 and simplifying the structure, reducing mold manufacturing costs and facilitating production. The distance between the rear of the dryer 200 and the outermost part of the dryer 200 (i.e., the outermost part of the fan cover 130) is reduced, which reduces the space occupied by the dryer 200, meets the requirements of the ultra-thin style, and makes it easier to integrate with other home decorations.

[0025] The various components of the fan cover assembly 100 of this utility model will be described below with reference to the accompanying drawings.

[0026] <Isolation Panel 110>

[0027] like Figure 2 and Figure 3 As shown, the isolation plate 110 is fixedly connected to the fan cover 130 by screws passing through the sound insulation cavity 140. Correspondingly, the screws pass through the sound-absorbing material 120 inside the sound insulation cavity 140. This method facilitates the assembly and disassembly of the isolation plate 110 and the fan cover 130.

[0028] An air duct (not shown) is formed between the side of the isolation plate 110 away from the soundproof material 120 and the rear cover plate 210 of the dryer 200. Referring to the air ducts in existing dryers, it will not be described in detail here.

[0029] <Soundproofing cavity 140, soundproofing material 120>

[0030] like Figure 1 and Figure 3 As shown, the fan cover 130 and the isolation plate 110 are interlocked to form a sound insulation cavity 140, and the sound-absorbing material 120 is located inside the sound insulation cavity 140. The shape of the sound-absorbing material 120 matches the fan cover 130, so that the sound-absorbing material 120 can fill the cross section of the sound insulation cavity 140 in the height direction, further improving the sound insulation effect of the fan cover assembly 100.

[0031] Continue to refer to Figure 1 The soundproofing material is in multiple 120s, for example, Figure 2There are three sound-damping materials 120. The three sound-damping materials 120 are combined to form a shape that matches the fan cover 130, further refining the components and facilitating assembly. At the same time, it is possible to replace parts of the sound-damping material 120, avoiding the material waste caused by replacing the entire sound-damping material 120, preventing excessive local vibration of the sound-damping material 120 that would reduce the sound-damping effect, achieving precise replacement and saving on the maintenance cost of the sound-damping material 120.

[0032] <Fan Cover 130>

[0033] Figure 4 This is a second structural schematic diagram of the clothes dryer 200 in this embodiment of the present utility model. (In conjunction with...) Figure 1 and refer to Figure 4 The fan cover 130 is semi-enclosed, with one side protruding outwards. A rear cover 210 is provided at the rear of the dryer 200. The protruding side of the fan cover 130 abuts against the rear cover 210 in the direction facing the dryer 200, thus achieving a locking mechanism. In this way, the rear of the dryer 200 is sealed by the fan cover 130.

[0034] like Figure 1 and Figure 3 As shown, an isolation rib 131 is provided in the upper middle position of the fan cover 130. The isolation rib 131 is circular and is used to isolate the roller bearing (not shown) of the dryer 200. Correspondingly, the isolation rib 131 passes through the soundproof material 120 and the isolation plate 110.

[0035] It is worth noting that in this embodiment, the fan cover assembly 100 integrates the isolation plate 110 and the soundproof material 120 on the fan cover 130. When installing the fan cover assembly 100 onto the dryer 200, it is only necessary to install the integrated fan cover assembly 100 onto the rear cover plate 210 of the dryer 200. This improves the degree of modularization, reduces the consumables required for installation (such as screws), simplifies the installation process, and saves labor costs.

[0036] like Figure 1 and Figure 2 As shown, a first sponge strip 141 and a second sponge strip 142 are provided on the side of the fan cover 130 facing the rear cover 210 of the dryer 200. The shape of the first sponge strip 141 matches the fan cover 130 and is connected to the inner circumference of the fan cover 130 in a close-fitting manner, so that the fan cover 130 and the rear cover 210 of the dryer 200 are tightly fitted. In this way, the airtightness between the dryer 200 and the fan cover 130 is ensured.

[0037] The shape of the second sponge strip 142 matches that of the isolation rib 131, and it is connected to the end of the isolation rib 131 in a close-fitting manner. In this way, dust in the circulating air duct, including the fan 220, is prevented from adhering to the surface of the roller bearing of the dryer 200, ensuring the normal rotation of the roller bearing.

[0038] <Clothes Dryer 200>

[0039] The second aspect of this utility model provides a clothes dryer 200 having the aforementioned fan cover assembly 100. This assembly enables rear-side sealing of the clothes dryer 200 and provides vibration damping and noise reduction when the fan 220 is rotating or the clothes dryer 200 is operating.

[0040] <Rear cover 210, Fan 220>

[0041] like Figure 2 and Figure 3 As shown, the dryer 200 includes a rear cover 210 and a fan 220 arranged adjacent to each other. The fan cover assembly 100 is fastened to the rear cover 210. In this way, the fan cover assembly 100 can seal the rear side of the dryer 200 through the rear cover 210, while also reducing vibration and noise when the fan 220 is in use or the dryer 200 is working.

[0042] The installation process of the fan cover assembly 100 in the embodiments of this utility model will be described below.

[0043] The first sponge strip 141 is placed around the fan cover 130, and the second sponge strip 142 is placed around the insulating rib 131. The sound-absorbing material 120 is placed on the fan cover 130. The insulating plate 110 is placed on the sound-absorbing material 120. Screws are then inserted through the insulating plate 110 and the sound-absorbing material 120, and integrated and fixed to the fan cover 130 to form the fan cover assembly 100. With the fan cover assembly 100 facing the rear end of the dryer 200, and the position of the insulating rib 131 corresponding to the roller bearing on the dryer 200, the fan cover assembly 100 is fastened to the rear cover 210 of the dryer 200, achieving a seal between the fan cover assembly 100 and the rear of the dryer 200.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
