It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The individual features described in the embodiments can be combined in any suitable manner without departing from the scope, for example different embodiments and aspects can be formed by combining different features. Various possible combinations of the various specific features of the invention are not described in detail to avoid unnecessary repetition.

The ventilation assembly provided by the embodiment of the invention is internally provided with the conveying channel, and can be used for equipment needing sealed conveying of generated fluid media (such as wind), such as a blast pipe of ventilation equipment. As shown in fig. 1, in the embodiment of the present invention, for convenience of understanding, the ventilation assembly is applied to a clothes treatment apparatus, and the clothes treatment apparatus at least has a clothes drying function, so that the ventilation assembly is used for conveying hot air flow required for drying clothes. When the clothes drying device works, hot air flows in the ventilation assembly and is conveyed into the barrel body 31 of the clothes device through the ventilation assembly, and drying treatment on wet clothes in the barrel body 31 is achieved.

As shown in fig. 2 and 3, the vent assembly includes a first vent body 11, a second vent body 12, and a joint 14. The first ventilating body 11 is installed at the laundry treating apparatus, and the second ventilating body 12 is connected to the first ventilating body 11. The first ventilating body 11 and/or the second ventilating body 12 are/is provided with the groove 13, so that after the first ventilating body 11 and the second ventilating body 12 are connected, a hollow structure is formed by the groove 13, an air channel is formed between the first ventilating body 11 and the second ventilating body 12, and hot air generated in the working process flows in the air channel and enters the barrel body. In the embodiment of the invention, the first ventilating body 11 and the second ventilating body 12 are arranged into two independent parts, and the two parts can be made of sheet metal parts wholly or partially, so that the first ventilating body and the second ventilating body have the advantages of convenience in molding and convenience in installation. In assembling, the first vent body 11 and the second vent body 12 are connected to each other, and further, a joint 14 is connected to the same end of the first vent body 11 and the second vent body 12 after they are connected. The joint 14 can provide clamping force, and under the clamping effect of the joint 14, the first ventilating body 11 and the second ventilating body 12 which are connected with each other can be further clamped, so that the connection between the first ventilating body 11 and the second ventilating body 12 is tighter, and the sealing performance of the air channel is improved. The joint 14 is also configured to communicate the air duct with the receiving cavity 311 (see fig. 1) of the tub, that is, the other end of the joint 14 is fixedly connected to the tub 31, and the joint 14 is provided with an air duct 141 for communicating the air duct with the receiving cavity 311 of the tub 31. Therefore, the connection of the joint 14 connects the air duct with the accommodating cavity 311 of the tub 31, so that the hot air in the air duct can flow into the tub 31 to dry the clothes.

In a possible embodiment, grooves 13 are formed in the first ventilating body 11 and the second ventilating body 12, the grooves 13 extend along the length direction of the first ventilating body 11 and the second ventilating body 12, and the grooves 13 between the first ventilating body 11 and the second ventilating body 12 are combined together to form an air channel after the first ventilating body 11 and the second ventilating body 12 are connected. Meanwhile, the two sides of the first ventilating body 11 and the second ventilating body 12 in the length direction are respectively provided with a connecting edge, when the first ventilating body 11 and the second ventilating body 12 are connected, the connecting edges on the two sides of the first ventilating body 11 and the connecting edges on the two sides of the second ventilating body 12 are correspondingly overlapped, and then the first ventilating body 11 and the second ventilating body 12 are fixed through screw fasteners or other modes, so that the connection between the first ventilating body 11 and the second ventilating body 12 is realized. As shown in fig. 4 and 5, in the embodiment of the present invention, in order to improve the sealing performance after the first ventilation body 11 and the second ventilation body 12 are connected, a sealing structure 18 is further provided at the connection position of the first ventilation body 11 and the second ventilation body 12. Namely, the sealing structure 18 is arranged between the connecting edges which are connected with each other at the two sides of the first ventilating body 11 and the second ventilating body 12, and the sealing structure 18 seals the gap between the two connecting edges which are overlapped with each other, thereby playing the role of improving the air duct sealing performance.

As shown in fig. 4 to 7, the seal structure 18 includes a seal groove 181 and a seal head 182. The sealing groove 181 is formed by bending the connecting edge, the sealing head 182 is an end portion of the connecting edge which is not bent, and the sealing head 182 can be coupled to the sealing groove 181. Thus, the sealing head 182 is inserted into the sealing groove 181 to achieve a sealing connection. When the sealing device is arranged, the sealing grooves 181 may be formed on the connecting edges at both sides of the first vent body 11, and the sealing heads 182 may be arranged on the connecting edges at both sides of the second vent body 12 that are not bent; the sealing heads 182 may be formed on the connecting edges of the two sides of the first ventilating body 11, and the sealing grooves 181 may be formed on the connecting edges of the two sides of the second ventilating body 12; or, the sealing groove 181 and the sealing head 182 may be respectively disposed on the connecting edges of the first ventilating body 11 and the second ventilating body 12, and when the first ventilating body 11 and the second ventilating body 12 are connected, the sealing groove 181 and the sealing head 182 on the two connecting edges overlapped with each other on the first ventilating body 11 and the second ventilating body 12 are corresponding in position, so that the matching connection can be realized. In this way, the sealing head 182 and the sealing groove 181 are engaged with each other to seal the first vent body 11 and the second vent body 12.

As shown in fig. 4 and 6, in a specific arrangement, according to installation requirements, the first ventilation body 11 and the second ventilation body 12 have a straight portion and a bent portion, and when connected, the sealing structure 18 on the straight portion of the first ventilation body 11 and the second ventilation body 12 is continuously arranged to realize sealing. When the bent part of the first ventilating body 11 and the bent part of the second ventilating body 12 are correspondingly connected, the sealing structure 18 can be arranged discontinuously, that is, the sealing structure 18 at the bent part is not continuously arranged but distributed discontinuously. Moreover, due to the curved surface structure of the bent part, the condition that two connecting edges overlapped with each other are not tightly attached easily occurs due to internal stress, and the air duct is not completely sealed. The sealing structure 18 is arranged at the bent part, and the sealing head 182 and the sealing groove 181 are matched and connected to limit the connection position, so that the two overlapped connecting edges at the bent part can be tightly attached, and the air duct can be kept in a sealed and air-tight connection state. In a specific arrangement, at least one of the two connecting edges that are overlapped can be manually bent at the position of the bent portion to achieve the sealing connection.

As shown in fig. 2 and 3, in the embodiment of the present invention, the joint 14 includes a joint body 142 and a cover 143 that are connected to each other, and the joint body 142 and the cover 143 may be connected to each other by a screw-type fastener or a snap-fit structure. Therefore, a clamping force can be provided in the process of connecting the joint body 142 and the cover 143, and the first vent body 11 and the second vent body 12 provided between the joint body 142 and the cover 143 are clamped and fastened. Specifically, referring to fig. 8, the joint body 142 includes a connection end 1421 and a first clamping end 1422 for connecting with the first vent body 11, the connection end 1421 is used for fixedly connecting with the barrel 31 (refer to fig. 1); the cover 143 includes a second clamping end 1431 for connecting with the second ventilating body 12 and a connecting head 1432 for connecting with the joint body 142, and the joint body 142 is provided with an installation notch 1423 and a fixing portion 1424. The shape of the mounting notch 1423 remains substantially the same as the contour shape of the cover 143. During assembly, the cover 143 is covered on the mounting notch 1423, and the first ventilating body 11 and the second ventilating body 12 are clamped between the first clamping end 1422 and the second clamping end 1431, and then the first clamping end 1422 and the second clamping end 1431 are connected to each other, and the connecting head 1432 is fixedly connected to the fixing portion 1424. In this way, the lid 143 and the joint body 142 can be fixedly connected to each other, and the first vent body 11 and the second vent body 12 can be sandwiched and fixed to each other. The cover 143 covers the mounting notch 1423, and the air transmission channel 141 is formed between the connector body 142 and the cover 143, for communicating the air duct with the accommodating cavity 311 of the barrel 31, so as to transmit the hot air in the air duct to the accommodating cavity 311 (refer to fig. 1) of the barrel 31.

As shown in fig. 3 and 8, in the embodiment of the present invention, in order to ensure the stability of the positions of the first and

second vent bodies

11 and 12 sandwiched between the first and second sandwiching ends 1422 and 1431, the joint 14 is configured to further include a first mounting structure 1425 and a second mounting structure 1433. A first mounting structure 1425 is disposed on the first clamping end 1422, and the first mounting structure 1425 is used for connecting the first ventilating body 11 (refer to fig. 2); a second mounting structure 1433 is disposed on the second clamping end 1431, the second mounting structure 1433 being configured to allow the second vent body 12 to be coupled thereto. After connection, the ends of the first vent body 11 and the second vent body 12, respectively, for connection to the connector 14 are sandwiched between the first mounting structure 1425 and the second mounting structure 1433. Specifically, the first mounting structure 1425 and the second mounting structure 1433 may be in the form of connection grooves, that is, the connection grooves are formed on the first clamping end 1422 and the second clamping end 1431 by means of a recess, respectively, and the shape of the connection groove on the first clamping end 1422 is preferably matched with the shape of the end for insertion connection on the first ventilating body 11, and similarly, the shape of the connection groove on the second clamping end 1431 is also preferably matched with the shape of the end for insertion connection on the second ventilating body 12. Therefore, when the first ventilation body 11 and the second ventilation body 12 are connected, one ends for connection and fixation are respectively inserted into the corresponding connecting grooves, assembly and connection can be reliably achieved, and under the limit fixation of the connecting grooves, the effect of limiting the connecting positions of the first ventilation body 11 and the second ventilation body 12 can be achieved. In addition, the length of the connecting groove can also limit the depth of the inserted connection of the first ventilating body 11 and the second ventilating body 12, so that the inserted length can meet the requirement of reliable connection. Meanwhile, in order to improve the sealing performance after connection, a sealing element can be arranged in the connecting groove, sealing is carried out through the sealing element, and the sealing performance after integral assembly is improved.

As shown in fig. 3 and 8, the connector 14 further includes a plug 144. The plug 144 is protruded from a surface of the connection end 1421 facing the barrel 31 (see fig. 1), and the plug 144 is configured to be inserted into a ventilation hole of the barrel 31. Therefore, when the connector 14 is fixedly connected with the barrel body 31, the plug 144 can be inserted into the ventilation hole in the barrel body 31, and the plug 144 can be matched with the ventilation hole to play a role in installation and positioning, so that the convenience in installation and connection between the connector 14 and the barrel body 31 is improved. Meanwhile, a flow passage 1441 communicated with the gas transmission passage 141 is provided inside the plug 144, and the flow passage 1441 is used for communicating the gas transmission passage 141 with the accommodating cavity 311 (refer to fig. 1) of the barrel 31, so that hot air in the air duct can enter the barrel.

In one possible embodiment, the vent assembly further includes a first sealing body 15, as shown in fig. 2 and 3. The first sealing body 15 is interposed between the connection head 1432 and the fixing portion 1424, and seals a gap between the connection head 1432 and the fixing portion 1424. Specifically, referring to fig. 8, the fixing portion 1424 is preferably provided in a manner matching the contour shape of the cover 143, and the first sealing body 15 is provided between the connection head 1432 and the fixing portion 1424. In this way, the first sealing body 15 is provided between the cover 143 and the joint body 142 except for the portion for sandwiching the first vent body 11 and the second vent body 12, so that when the cover 143 and the joint body 142 are assembled and connected, the first sealing body 15 is elastically deformed by pressing the first sealing body 15, and the gap between the connection head 1432 and the fixing portion 1424 can be sealed, and the sealing property of the gas transmission passage 141 can be ensured.

In one possible embodiment, the vent assembly further includes a second sealing body 16, as shown in fig. 2 and 3. Specifically, along the shape of the fixing portion 1424, a mounting groove 1426 (see fig. 8) is formed in the fixing portion 1424, the second sealing body 16 is disposed in the mounting groove 1426, and the connecting head 1432 is pressed against the second sealing body 16. In this way, when the connection head 1432 is connected to the fixing part 1424, the connection head 1432 presses the second sealing body 16 to elastically deform the second sealing body 16, thereby sealing a gap between the connection head 1432 and the fixing part 1424. Further, by providing the second sealing body 16 in the mounting groove 1426, the mounting position of the second sealing body 16 can be defined by the mounting groove 1426, and it is possible to ensure that the sealing position does not shift even if the second sealing body 16 is pressed, and sealing reliability is high. In this arrangement, the second sealing body 16 and the first sealing body 15 together seal the gap between the connecting head 1432 and the fixing portion 1424, thereby further improving the sealing performance of the air duct 141.

In one possible embodiment, the first sealing body 15 is provided as being made of sponge, while the second sealing body 16 is provided as being made of rubber or silicone or the like. Because the sponge can take place elastic deformation's performance great, compare in sponge material, rubber or silica gel can take place elastic deformation's performance slightly less than sponge material. This is provided so that the top surface of the first sealing body 15 is higher than the top surface of the second sealing body 16. Therefore, even if the height of the first sealing body 15 is higher than the height of the second sealing body 16 when the cover 143 and the joint main body 142 are assembled and connected, the first sealing body 15 can be elastically deformed by being pressed by a larger amount than the second sealing body 16, and therefore the first sealing body 15 does not block the second sealing body 16 from being elastically deformed by being pressed by a force, and both the first sealing body 15 and the second sealing body 16 can be deformed by being pressed. Therefore, under the double sealing action of the first sealing body 15 and the second sealing body 16, the sealing performance between the cover body 143 and the joint body 142 is reliably improved, and the sealing performance of the air transmission channel 141 is further ensured.

As shown in fig. 3 and 8, in one possible embodiment, the joint 14 further includes a rib 146. The rib 146 is disposed on the connector body 142 around the contour of the mounting notch 1423. Thus, an installation step is formed between the rib 146 and the fixing portion 1424, the cover 143 is disposed on the installation step, and the position where the cover 143 covers the installation notch 1423 can be located by the installation step, so that the convenience of installation between the cover 143 and the joint body 142 is improved. Meanwhile, since the first sealing body 15 (see fig. 2) is disposed on the fixing portion 1424, the mounting step can also position the mounting position of the first sealing body 15, so that the sealing position can be maintained without being displaced even if the first sealing body 15 is pressed, thereby ensuring reliable sealing.

The ventilation assembly provided by the embodiment of the invention adopts the structure that the first ventilation body 11 and the second ventilation body 12 are connected with each other, and an air channel is formed between the first ventilation body 11 and the second ventilation body 12. Meanwhile, the joint 14 is arranged at the same end of the first ventilating body 11 and the second ventilating body 12 after the first ventilating body 11 and the second ventilating body 12 are connected, the first ventilating body 11 and the second ventilating body 12 can be clamped through the joint 14, the connection tightness between the first ventilating body 11 and the second ventilating body 12 is improved, and the air channel can be reliably sealed. Moreover, the joint 14 is internally provided with double seals, so that the whole sealing performance of the ventilation assembly is further improved, and the use requirement of reliably conveying hot air flow through the ventilation assembly is met.

As shown in fig. 9 and 10, the embodiment of the present invention further provides a drying component 2, which includes a blower 21, the above-mentioned ventilation assembly, a heating element 22 and a volute 23.

The volute 23 may be fixedly mounted by being connected to the ventilation assembly and/or the barrel 31, and after the volute 23 is fixedly mounted, the fan 21 is located in the cavity 231 and rotates in the cavity 231. Specifically, the fan 21 is disposed at one end of the first ventilating body 11, which is not connected to the joint 14 after being connected to the second ventilating body 12, and the wind generated by the rotation of the fan 21 can be output from the wind outlet 232 and enter the wind channel. The heating element 22 can generate heat after being powered on, so that the air in the air duct can be heated, and the hot air flows to form hot air flow and is input into the accommodating cavity 311 of the tub 31, so as to dry the wet clothes in the accommodating cavity 311 of the tub 31.

Specifically, the temperature detecting element 20 is mounted on the first ventilation body 11 and/or the second ventilation body 12, and in order to improve the sealing performance of the air duct, a mounting structure 17 that is not communicated with the inside of the air duct is provided on the first ventilation body 11 and/or the second ventilation body 12, and the temperature detecting element 20 is mounted in the mounting structure 17. With this arrangement, the structural integrity of the first vent body 11 and/or the second vent body 12 is not damaged due to the mounting structure 17, and the temperature in the air duct can be transmitted into the mounting structure 17. Therefore, the arrangement mode not only can detect the temperature in the air duct, but also ensures the sealing performance of the air duct, avoids the situation that the sealing performance of the air duct is damaged due to the arrangement of the temperature detection piece 20, meets the use requirement that the sealing performance of the air duct can be ensured while the temperature in the air duct is detected, and the installation structure 17 and the temperature detection piece 20 are good in arrangement ingeniousness.

The open end of the blind mounting hole faces outward (i.e., the side away from the air duct), and the temperature detecting member 20 is typically a temperature sensor. The blind mounting holes can reduce the wall thickness of the first ventilation body 11 and/or the second ventilation body 12, and the temperature in the air duct can be quickly transferred to the inner wall surfaces of the blind mounting holes through heat transfer. Thus, when mounting, the temperature detection member 20 is fixed in the mounting blind hole, and the temperature detection member 20 is brought into close contact with the inner wall surface of the mounting blind hole. Therefore, the temperature on the inner wall surface of the mounting blind hole can be detected by the temperature detection piece 20 in time, and the accuracy of temperature detection is improved.

In the present embodiment, it is adopted that the mounting structure 17 is provided on the second vent body 12.

Specifically, since the temperature detecting member 20 is not directly disposed in the air duct, the temperature detecting member 20 detects the temperature by means of thermal conductivity sensing. Therefore, in an actual setting, the difference between the value of the actual temperature in the air duct and the value of the temperature detected by the temperature detecting element 20 can be corrected to ensure the accuracy of the temperature detection. Meanwhile, a plurality of mounting structures 17 can be arranged at intervals, and a temperature detection piece 20 is fixed in each mounting structure 17. Therefore, the temperature in the air duct is detected by the plurality of temperature detection pieces 20, and the accuracy of temperature detection in the air duct is improved in the temperature detection mode.
