Detailed Implementation

[0020] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0021] Reference Figure 1 and Figure 2 The hot air duct shell of the first aspect of this utility model includes: an upper shell 100 and a lower shell 200; the upper shell 100 includes a first air inlet 110 and a first air guide 120, the first air inlet 110 and the first air guide 120 are arranged sequentially along the air outlet direction, the first air inlet 110 and the first air guide 120 are integrally formed to form the upper shell 100, and the edge of the upper shell 100 is bent downward to form a first sidewall 140; the lower shell 200 includes a second The air intake 210 and the second air guide 220 are arranged sequentially along the air outlet direction. The second air intake 210 and the second air guide 220 are integrally formed to form the lower housing 200. The edge of the lower housing 200 is bent upward to form the second side wall 240. The second side wall 240 is inserted and engaged with the first side wall 140 to splice the upper housing 100 and the lower housing 200. The upper housing 100 and the lower housing 200 are connected together by screws.

[0022] The first air intake 110 is used to install the motor, and the second air intake 210 is provided with an air inlet 211. When the motor rotates, air enters through the air inlet 211. The first guide section 120 and the second guide section 220 cooperate to form an air duct. The heating element extends into the air duct from one side. The air entering the air duct from the air inlet 211 is heated into hot air by the heating element. The second guide section 220 has an air outlet 230, from which the hot air flows out. By integrally molding the first air intake 110 and the first guide section 120, as well as the second air intake 210 and the second guide section 220, the number of parts is reduced, the assembly process of the hot air duct shell is simplified, the skill requirements for the operator are reduced, and the assembly accuracy and sealing are improved. At the same time, the integral molding also improves the structural strength of the upper shell 100 and the lower shell 200.

[0023] Understandably, referring to Figure 3 A insertion groove 141 is provided on the side of the first sidewall 140 facing the second sidewall 240, and an insertion part 241 protrudes from the second sidewall 240. The insertion part 241 matches the insertion groove 141, and the insertion part 241 and the insertion groove 141 are inserted into each other. Through the insertion groove 141 and the insertion part 241, the upper housing 100 and the lower housing 200 can be quickly positioned. After the upper housing 100 and the lower housing 200 are assembled together, the positional offset during assembly can be reduced, and it is convenient to quickly lock with screws, thereby improving assembly efficiency and enhancing the sealing between the upper housing 100 and the lower housing 200.

[0024] It is also understandable that, referring to Figure 3 A sealant is provided inside the insertion groove 141, located between the inner wall of the insertion groove 141 and the insertion part 241. By providing sealant inside the insertion groove 141, the sealant fills the gap between the insertion groove 141 and the insertion part 241, and simultaneously abuts against both the inner wall of the insertion groove 141 and the insertion part 241, further enhancing the sealing performance between the upper housing 100 and the lower housing 200. It should be noted that the sealant can be common materials such as silicone rubber and polyurethane adhesive, which have good high-temperature resistance and aging resistance, and can maintain a sealing effect for a long time.

[0025] Understandably, referring to Figure 1 and Figure 2 The first air intake 110 has a first recess 113, and the first recess 113 has a plurality of first threaded holes 114. The motor is installed into the first recess 113, which facilitates quick positioning of the motor and improves assembly efficiency. Then, the motor is locked by screws threaded into the first threaded holes 114, which is convenient and quick.

[0026] Understandably, referring to Figure 1 and Figure 2 The first air intake 110 is provided with multiple first reinforcing ribs 111, which are arranged radially along the first recess 113 and are spaced apart circumferentially around the first recess 113. When the motor is locked, the first air intake 110 is subjected to applied pressure. By providing the first reinforcing ribs 111, the structural strength of the first air intake 110 is enhanced, preventing damage to the upper housing 100.

[0027] It is also understandable that, referring to Figure 1 and Figure 2 The first air intake 110 is provided with at least one second reinforcing rib 112, which is arranged circumferentially along the first recess 113. The second reinforcing rib 112 is also connected to multiple first reinforcing ribs 111. By adding the second reinforcing rib 112 and connecting it with the first reinforcing ribs 111, the first reinforcing ribs 111 and the second reinforcing ribs 112 are connected to form a mesh structure, which further improves the structural strength of the first air intake 110, increases the load-bearing capacity of the first air intake 110, and reduces the risk of damage.

[0028] Understandably, referring to Figure 1 and Figure 2The first air intake 110 is equipped with a cold water nozzle 115 and a protective plate 116, with the protective plate 116 surrounding the cold water nozzle 115. The cold water nozzle 115 connects to an external water source, facilitating the introduction of cold water into the air duct, accelerating the cooling rate of the upper housing 100 and lower housing 200, and preventing overheating that could damage other components. The protective plate 116 protects the cold water nozzle 115, reducing the risk of damage. Furthermore, by placing the cold water nozzle 115 in the first air intake 110, when cold water is introduced, the fan blades disperse the water into a mist, which flows along the air duct towards the air outlet 230, increasing the contact area between the cold water and the upper housing 100 and lower housing 200, thus improving the cooling effect.

[0029] Understandably, referring to Figure 1 and Figure 2 An installation portion 130 is provided on the outer side of the first guide portion 120. The installation portion 130 has an installation hole 131 and a second threaded hole 132. The installation hole 131 passes through the first guide portion 120. The installation hole 131 is used to position the temperature detector. The temperature detector is installed into the installation hole 131 by screws engaging with the second threaded hole 132, which facilitates quick installation of the temperature detector and improves assembly efficiency. The detection end of the temperature detector extends into the air duct through the installation hole 131, improving the temperature detection accuracy.

[0030] The fan of the second aspect embodiment of this utility model includes a hot air duct housing as described in the first aspect embodiment of this utility model. A first air inlet 110 is used to mount a motor, and a second air inlet 210 is provided with an air inlet 211. When the motor rotates, air enters through the air inlet 211. A first guide section 120 and a second guide section 220 cooperate to form an air duct. A heating element extends into the air duct from one side. The air entering the air duct from the air inlet 211 is heated into hot air by the heating element. The second guide section 220 has an air outlet 230 from which the hot air flows out. By integrally molding the first air inlet 110 and the first guide section 120, as well as the second air inlet 210 and the second guide section 220, the number of parts is reduced, the assembly process of the hot air duct housing is simplified, the skill requirements for the operator are reduced, and the assembly accuracy and sealing performance are improved. Simultaneously, the integral molding also improves the structural strength of the upper housing 100 and the lower housing 200.

[0031] The washing machine according to a third aspect of this utility model includes a fan according to a second aspect of this utility model. The first air inlet 110 and the first air guide 120 are integrally formed, as are the second air inlet 210 and the second air guide 220, which improves the structural strength of the upper shell 100 and the lower shell 200, reduces the number of parts in the hot air duct shell, simplifies the assembly process, reduces human-caused risks, and improves assembly accuracy and sealing performance.

[0032] The above description is only a preferred embodiment of the present utility model.
