Referring to fig. 3, the drying tunnel assembly 1 includes a first single body 11 and a second single body 12. The first unit 11 is fixedly installed on the laundry treating apparatus, preferably, on a tub 31 (refer to fig. 1) of the laundry treating apparatus. The second unit 12 is connected to the first unit 11, and an air duct is formed between the first unit 11 and the second unit 12, through which hot air is introduced into the tub 31. Specifically, the first unit 11 includes a ventilation portion 114, a mounting portion 111, and a bent portion 115. The second single body 12 is connected to the ventilation part 114, thereby forming an air duct between the ventilation part 114 and the second single body 12; the bent portion 115 is used for connecting the ventilation portion 114 and the mounting portion 111 to form a whole, so that the whole formed structure between the ventilation portion 114 and the mounting portion 111 after being connected by the bent portion 115 is a stepped structure, which is matched with the shape of the barrel 31 for mounting the drying tunnel assembly 1, so as to meet the mounting and fixing requirements of the drying tunnel assembly 1. Specifically, the ventilation portion 114 is located forward and upward of the mounting portion 111 in the direction in which the wind flows. In this way, the position of the mounting portion 111 is lowered compared to the plane of the vent portion 114, so that the plane of the mounting portion 111 is lower than the plane of the vent portion 114, and the outline shape formed by connecting the planes of the vent portion 114, the mounting portion 111 and the bent portion 115 is substantially stepped. The stepped configuration reduces the height of the mounting portion 111, i.e., reduces the depth to which the mounting portion 111 is formed. By the arrangement, the fan installation can be met, the installation part 111 with the large punch forming depth is not needed when the sheet metal part punch forming installation part 111 is used, the punch forming depth required by the installation part 111 is reduced, the production difficulty of the installation part 111 is reduced, the convenience of machining and forming is improved, the installation part 111 can be prevented from generating wrinkles, the inner wall surface is kept to be a flat surface, and the ventilation performance is improved.

As shown in fig. 2 and 3, in a possible embodiment, the bent portion 115 may be inclined or horizontal according to actual assembly requirements. And the planes between the mounting portion 111 and the ventilation portion 114 may be parallel or non-parallel to each other. The drying tunnel assembly 1 formed by the arrangement is matched with the shape of the installation position on the barrel body 31 in shape, and when the drying tunnel assembly is installed, the ventilation part 114 and the installation part 111 can be basically attached to the installation position on the barrel body 31, so that the installation is convenient and fixed, and the reliability and the convenience after the installation are improved.

In one possible embodiment, the drying tunnel assembly 1 further comprises a joint 14, as shown in figures 1 and 2. One end of the joint 14 is connected to the same end of the first unit 11 as the second unit 12, and the other end of the joint 14 is connected to the tub 31 of the laundry treating apparatus. Specifically, the tub 31 is provided with a vent hole for inputting a hot air flow into the tub 31, and then the air passages formed inside the first unit 11 and the second unit 12 are connected to the vent hole. Thus, the transition connection is made by the joint 14, and the convenience of installation is improved. Also, rather than directly through the first monomer 11 and the second monomer 12. Transitioning the connection through joint 14 also reduces the complexity of the shape of first cell 11 and second cell 12, facilitating the manufacturing process of first cell 11 and second cell 12.

As shown in fig. 4, in a possible embodiment, since the air channel is formed between the ventilation part 114 and the second single body 12, a groove 13 may be provided on the ventilation part 114 and/or the second single body 12, so that after the ventilation part 114 and the second single body 12 are connected, a hollow structure is formed by the groove 13, and the air channel is formed between the ventilation part 114 and the second single body 12. In the embodiment of the invention, the first single body 11 and the second single body 12 are arranged into two independent parts, and the two parts can be manufactured by wholly or partially adopting sheet metal parts, so that the forming is convenient and the installation is convenient. First single body 11 second single body 12 joint 14 first single body 11 second single body 12 bent portion 115

As shown in fig. 4 and 5, in the embodiment of the present invention, the ventilation portion 114 and the second single body 12 are both provided with the grooves 13, the grooves 13 respectively extend along the length direction of the ventilation portion 114 and the second single body 12, and after the ventilation portion 114 and the second single body 12 are connected, the grooves 13 therebetween are combined together to form the air duct. Simultaneously, equally divide along length direction's both sides at whole first monomer 11 and second monomer 12 and do not be provided with the connection limit, when connecting, overlap each other with the connection limit of both sides on first monomer 11 and the connection limit correspondence of both sides on second monomer 12 and establish, then fix through screw type fastener or other modes, just realized being connected between first monomer 11 and the second monomer 12. Referring to fig. 5, in the embodiment of the present invention, in order to improve the sealing performance after the first single body 11 and the second single body 12 are connected, and prevent the hot air flowing in the air duct from leaking, a sealing structure 18 is further disposed at the connection position of the first single body 11 and the second single body 12. That is, the sealing structure 18 is arranged between the connecting edges which are connected with each other at the two sides of the first single body 11 and the second single body 12, and the sealing structure 18 seals the gap between the connecting edges which are overlapped with each other, thereby improving the sealing performance of the air duct.

Specifically, as shown in fig. 6 to 8, 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. Accordingly, the seal head 182 is inserted into the seal groove 181, thereby achieving a sealed connection. When the sealing device is arranged, the sealing groove 181 may be formed on the connecting edges at both sides of the first single body 11, and the sealing head 182 may be formed on the connecting edges at both sides of the second single body 12 that are not bent; the sealing head 182 may be formed on the connecting edges of the two sides of the first single body 11, and the sealing groove 181 may be formed on the connecting edges of the two sides of the second single body 12; the sealing grooves 181 and the sealing heads 182 may be respectively disposed on the connecting edges of the first single body 11 and the second single body 12, and when the two connecting edges are connected, the sealing grooves 181 and the sealing heads 182 on the two connecting edges overlapped with each other on the first single body 11 and the second single body 12 are positioned correspondingly to realize matching connection. . In this way, the first unit 11 and the second unit 12 are hermetically connected by the fitting connection between the sealing head 182 and the sealing groove 181.

As shown in fig. 5 and 6, in a specific arrangement, according to installation requirements, the first single body 11 and the second single body 12 are integrally shaped to have a straight portion and a bent portion (e.g., at an end for connecting with the joint 14), and when connecting, the sealing structure 18 on the straight portion of the first single body 11 and the second single body 12 is continuously arranged to realize sealing. When the bent part of the first single body 11 and the bent part of the second single body 12 are correspondingly connected, the sealing structure 18 can be arranged discontinuously, namely, the sealing structure 18 arranged at the bent part is not continuously arranged but distributed discontinuously. Moreover, due to the curved surface structure of the bent part, the two overlapped connecting edges are not tightly attached easily due to internal stress, so that the air duct is not completely sealed. The sealing structure 18 is arranged at the position of the bent part, and the sealing head 182 and the sealing groove 181 are matched and connected to play a role of limiting connection, so that two connecting edges which are overlapped at the position of 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. 4 and 9, in a possible embodiment, the joint 14 can provide a clamping force, and one end of the joint 14 is connected to the same end of the first single body 11 and the second single body 12 after being connected, so that the joint can further clamp the first single body 11 and the second single body 12 connected with each other, so that the connection between the first single body 11 and the second single body 12 is tighter, and the sealing performance of the air duct is improved. Moreover, the joint 14 is arranged to communicate the air duct with the accommodating cavity 311 of the barrel 31, that is, the joint 14 is fixedly connected to the barrel 31, and the air transmission passage 141 for communicating the air duct with the accommodating cavity 311 of the barrel 31 is arranged inside the joint 14. Therefore, the air transmission channel 141 is located between the air channel and the vent hole on the barrel 31 through the connection between the joint 14 and the barrel 31, so as to communicate the air channel with the accommodating cavity 311 of the barrel 31, and the hot air in the air channel can flow into the accommodating cavity 311 of the barrel 31 to dry the clothes.

As shown in fig. 9 and 10, in the embodiment of the present invention, the joint 14 includes a joint body 142 and a cover 143 connected to each other. The connector body 142 and the cover 143 may be connected to each other by a screw-type fastener or a snap structure. Accordingly, a clamping force can be provided during the process of connecting the joint body 142 and the cover 143, and the first unit 11 (see fig. 6) and the second unit 12 disposed between the joint body 142 and the cover 143 can be clamped and fastened. Specifically, the joint body 142 includes a connection end 1421 and a first clamping end 1422 for connecting with the first single body 11, and the connection end 1421 is used for fixedly connecting with the barrel 31; the cover 143 includes a second clamping end 1431 for connecting with the second unit 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, the first unit 11 and the second unit 12 are clamped between the first clamping end 1422 and the second clamping end 1431, 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 cover 143 and the joint body 142 can be fixedly connected to each other, and the first unit 11 and the second unit 12 can be clamped 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, and is used for communicating the air duct with the accommodating cavity 311 of the barrel 31, so as to transmit the hot air flow in the air duct to the accommodating cavity 311 of the barrel 31.

As shown in fig. 9 and 10, in the embodiment of the present invention, in order to ensure the stability of the positions of the first single body 11 (refer to fig. 4) and the second single body 12 sandwiched between the first sandwiching end 1422 and the second sandwiching end 1431, the joint 14 is configured to further include the first mounting structure 1425 and the 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 single body 11; a second mounting structure 1433 is disposed on the second clamping end 1431, the second mounting structure 1433 being configured to allow the second unit 12 to be connected. After connection, the ends of the first and second

unitary bodies

11, 12, respectively, for connection to the fitting 14 are sandwiched between the first and second mounting

structures

1425, 1433. Specifically, the first mounting structure 1425 and the second mounting structure 1433 may be both in the form of a connecting groove, that is, the connecting groove is formed on the first clamping end 1422 and the second clamping end 1431 by a concave manner, and the shape of the connecting groove on the first clamping end 1422 is preferably matched with the shape of the end of the first single body 11 for insertion connection, and similarly, the shape of the connecting groove on the second clamping end 1431 is also preferably matched with the shape of the end of the second single body 12 for insertion connection. Therefore, when the first single body 11 and the second single 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 single body 11 and the second single body 12 can be achieved. Moreover, the length of the connecting groove can also limit the depth of the inserted connection of the first single body 11 and the second single 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. 9 and 10, the connector 14 further includes a plug 144. The plug 144 is protruded from a surface of the connector body 142 facing the barrel 31, and the plug 144 is inserted into a ventilation hole of the barrel 31 (see fig. 1). Like this, when joint 14 and staving 31 fixed connection, can insert the ventilation hole on the staving 31 with bayonet 144, through the cooperation of bayonet 144 and ventilation hole, can play the effect of installation location, improved the convenience of erection joint between joint 14 and the staving 31. Meanwhile, a flow passage 1441 communicated with the gas transmission passage 141 is arranged inside the plug 144, and the flow passage 1441 is used for communicating the gas transmission passage 141 with the accommodating cavity 311 of the barrel body 31, so that hot air in the air duct can enter the barrel body.

In one possible embodiment, the joint 14 further includes a first sealing body 15, as shown in fig. 4 and 10. 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, 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 unit 11 and the second unit 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 performance of the gas transmission passage 141 can be ensured.

In one possible embodiment, as shown in fig. 4 and 10, the joint 14 further includes a second sealing body 16. Specifically, along the shape of the fixing portion 1424, a mounting groove is formed in the fixing portion 1424, the second sealing element 16 is disposed in the mounting groove 1426, and the connecting head 1432 is pressed against the second sealing element 16. In this way, in the process of connecting the connecting head 1432 to the fixing portion 1424, the second sealing body 16 is pressed by the connecting head 1432, so that the second sealing body 16 is elastically deformed, and a gap between the connecting head 1432 and the fixing portion 1424 is sealed. 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 a 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 is assembled to the joint main body 142, the first sealing body 15 can be elastically deformed by being pressed more than the second sealing body 16, and therefore the first sealing body 15 under a force does not block the second sealing body 16 from being elastically deformed, and both the first sealing body 15 and the second sealing body 16 can be deformed by being pressed. Thus, 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 gas transmission channel 141 is further ensured.

As shown in fig. 4 and 10, 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 part 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 convenience in installation between the cover 143 and the connector body 142 is improved. Meanwhile, since the first sealing body 15 is disposed on the fixing portion 1424, the mounting step can also position the mounting position of the first sealing body 15, so that even if the first sealing body 15 is squeezed, the sealing position can still be kept from shifting, and reliable sealing is ensured.

As shown in fig. 5 and 11, in a possible embodiment, since the heating element 22 is disposed in the air duct for heating the air in the air duct, in order to detect the temperature of the hot air in the air duct, so that the temperature of the heated air in the air duct can be maintained within a proper range, the temperature detecting element 20 is disposed to detect the temperature in the air duct, the temperature detecting element 20 detects the temperature of the hot air in the air duct in real time, and can feed back a temperature detecting signal, so that the control system can control the operating state of the heating element 22 according to the temperature detecting signal, and further, the temperature in the air duct can be maintained within a proper range. Specifically, the temperature detecting member 20 is mounted on the first single body 11 (see fig. 4) and/or the second single body 12, and in order to improve the sealing performance of the air duct, in the embodiment of the present invention, a mounting structure 17 that is not communicated with the inside of the air duct is provided on the first single body 11 and/or the second single body 12, and the temperature detecting member 20 is mounted in the mounting structure 17. With this arrangement, the structural integrity of the first unit 11 and/or the second unit 12 is not damaged by the mounting structure 17, and the temperature in the air duct can be transmitted to 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 ingeniously.

In one possible embodiment, the mounting structure 17 is configured as a blind mounting hole, as shown in fig. 11. 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 single body 11 and/or the second single 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.

As shown in fig. 11, in the embodiment of the present invention, it is adopted that the bottom of the blind mounting hole is protruded toward the inside of the air duct. Namely, the blind mounting holes formed in the first single body 11 and/or the second single body 12 protrude toward the inside of the air duct, so as to form a bulge structure. Set up like this, wind blows to the swell at the in-process that flows in the wind channel, and the heat of wind can be received to the swell, and the temperature that received heat made the swell structure risees to conduct to temperature detection spare 20 through the heat transfer, make temperature detection spare 20 can in time detect the temperature state, realize the detection to the temperature in the wind channel. In the present embodiment, the mounting structure 17 is disposed on the second unit 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 member 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.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
