As shown in fig. 3-5, in one possible embodiment, the first connection structure 313 includes a connection post 3131 and a connection hole 3132 provided on the connection post 3131. The coupling hole 3132 is generally extended in the axial direction of the coupling post 3131, and the coupling hole 3132 is preferably of a screw structure so that a screw-type fastener can be screwed in to achieve screw coupling. And the second connection structure 237 includes a connection lug 2371 and a through hole 2372 provided on the connection lug 2371, the through hole 2372 being used for passing one end of a fastener and screwing into the connection hole 3132 on the connection post 3131 to enable connection between the first connection structure 313 and the second connection structure 237, thereby enabling the scroll casing 23 to be fixedly mounted on the tub 31.

As shown in fig. 1 and 6, in one possible embodiment, the tunnel body includes a first tunnel cell 11, a second tunnel cell 12, a blower 21, and a heating element 22. The first drying tunnel monomer 11 is installed on the clothes treating apparatus, the second drying tunnel monomer 12 is connected with the first drying tunnel monomer 11, and specifically, a groove 13 is formed on the first drying tunnel monomer 11 and/or the second drying tunnel monomer 12, so that after the first drying tunnel monomer 11 and the second drying tunnel monomer 12 are connected, a hollow structure is formed through the groove 13, and an air channel is formed between the first drying tunnel monomer 11 and the second drying tunnel monomer 12. In the embodiment of the invention, the first drying tunnel monomer 11 and the second drying tunnel monomer 12 are arranged into two independent parts, and all or part of the two parts can be manufactured by sheet metal parts, so that the drying tunnel has the advantages of convenient molding and convenient installation.

As shown in fig. 5 and 6, the fan 21 is used for conveying wind into the air duct, and the volute 23 is covered above the fan 21, and the fan 21 is covered by the volute 23, so that the use safety is improved. The interior of the scroll casing 23 is formed with a cavity 231 accommodating the blower 21 and an air outlet 232 for supplying air to the air duct, the air outlet 232 being in communication with the air duct. In particular, the fan 21 may be connected to the volute 23 and/or the first drying tunnel cell 11 to achieve a fixed installation. After the scroll casing 23 is fixed, the fan 21 is positioned in the cavity 231, and rotates in the cavity 231 to generate wind, which is output from the air outlet 232 and enters the air duct. The heating member 22 is disposed in the air duct, generates heat after being energized to heat the air in the air duct, and the hot air flows to form a hot air flow and is inputted into the accommodating chamber 311 of the tub 31 for drying the wet laundry in the accommodating chamber 311 of the tub 31.

In the drying tunnel provided in the embodiment of the present invention, during the drying process of the clothes, the air is heated to become dry hot air flow, and enters into the accommodating cavity 311 of the tub body 31, and takes away the water vapor on the wet clothes to be converted into warm and humid air, and the warm and humid air can be directly exhausted after being exhausted from the accommodating cavity 311 of the tub body 31; the water may be precipitated by the condensation device, converted into low-temperature dry air, then sucked into the duct by the fan 21, heated again to dry hot air, and then fed into the accommodating chamber 311 of the tub 31 to dry the laundry. The drying tunnel body has various working modes for clothes drying treatment, and the specific setting mode can be selected according to actual use requirements, and is not limited herein.

As shown in fig. 2, in the embodiment of the present invention, grooves 13 are formed on the first drying tunnel monomer 11 and the second drying tunnel monomer 12, the grooves 13 are respectively extended along the length direction of the first drying tunnel monomer 11 and the second drying tunnel monomer 12, and after the first drying tunnel monomer 11 and the second drying tunnel monomer 12 are connected, the grooves 13 therebetween are combined together to form an air duct. Meanwhile, connecting edges are respectively arranged on two sides of the first drying tunnel monomer 11 and the second drying tunnel monomer 12 along the length direction, and when the connecting edges are connected, the connecting edges on two sides of the first drying tunnel monomer 11 and the connecting edges on two sides of the second drying tunnel monomer 12 are correspondingly overlapped with each other, and then are fixed through screw fasteners or other modes, so that the connection between the first drying tunnel monomer 11 and the second drying tunnel monomer 12 is realized. In the embodiment of the present invention, as shown in fig. 7 and 8, in order to improve the tightness of the first drying tunnel monomer 11 and the second drying tunnel monomer 12 after being connected, the hot air flowing in the air duct will not leak, and a sealing structure 18 is further disposed at the connection position of the first drying tunnel monomer 11 and the second drying tunnel monomer 12. Namely, a sealing structure 18 is arranged between the connecting edges of the two sides of the first drying tunnel monomer 11 and the second drying tunnel monomer 12, and a gap between the two mutually overlapped connecting edges is sealed through the sealing structure 18, so that the effect of improving the air duct tightness is achieved.

Specifically, as shown in fig. 7 to 10, the seal structure 18 includes a seal groove 181 and a seal head 182. The seal groove 181 is formed by bending the connecting edge, and the seal head 182 is an end portion of the connecting edge which is not bent, and the seal head 182 can be connected to the seal groove 181 in a fitting manner. Thus, the sealing head 182 is inserted into the sealing groove 181 to achieve a sealing connection. When the two-side sealing device is arranged, a sealing groove 181 can be formed on the connecting edges at two sides of the first drying tunnel monomer 11, and the connecting edges which are not bent at two sides of the second drying tunnel monomer 12 are arranged to be sealing heads 182; alternatively, the connecting edges at two sides of the first drying tunnel monomer 11 may form sealing heads 182, and the connecting edges at two sides of the second drying tunnel monomer 12 may be configured as sealing grooves 181; the sealing grooves 181 and the sealing heads 182 are respectively arranged on the connecting edges of the first drying tunnel monomer 11 and the second drying tunnel monomer 12, and when the sealing heads are connected, the positions of the sealing grooves 181 and the sealing heads 182 on the two mutually overlapped connecting edges of the first drying tunnel monomer 11 and the second drying tunnel monomer 12 are corresponding to each other so as to realize matching connection. By the arrangement, the first drying tunnel monomer 11 and the second drying tunnel monomer 12 are in sealing connection through the matched connection between the sealing head 182 and the sealing groove 181.

In a specific arrangement, as shown in fig. 7 and fig. 9, according to the installation requirement, the shape of the whole first drying tunnel unit 11 and the second drying tunnel unit 12 has a straight part and also has a bent part, and when the two drying tunnel units are connected, the sealing structure 18 positioned on the straight parts of the first drying tunnel unit 11 and the second drying tunnel unit 12 is sealed in a continuous arrangement mode. When the bent part of the first drying tunnel monomer 11 and the bent part of the second drying tunnel monomer 12 are correspondingly connected, the sealing structure 18 can be discontinuously arranged, namely the sealing structure 18 at the position of the bent part is discontinuously arranged, and the sealing structure is discontinuously distributed. Moreover, the bending part is in a curved surface structure, so that the situation that the joint of two mutually overlapped connecting edges is not tight is easy to occur due to internal stress, and the air duct is not completely sealed. The sealing structure 18 is arranged at the position of the bent part, the sealing head 182 and the sealing groove 181 are connected in a matched mode, the function that the connecting position is limited is achieved, the two mutually overlapped connecting edges at the position of the bent part can be kept tightly attached, and the air duct can be kept in a sealed and air-leakage-free connecting state. In a specific arrangement, at least one of the two connecting edges which are to be stacked can be manually bent at the position of the bent portion to achieve a sealed connection.

As shown in fig. 6 and 11, in one possible embodiment, the laundry treating device further comprises a joint 14. One end of the joint 14 is connected with the drying tunnel body, and the other end of the joint 14 is connected with the barrel body 31. Specifically, one end of the joint 14 is connected to the same end of the first drying tunnel monomer 11 and the second drying tunnel monomer 12 after being connected, the joint 14 can provide clamping force, and under the clamping action of the joint 14, the joint can further clamp the first drying tunnel monomer 11 and the second drying tunnel monomer 12 which are connected with each other, so that the connection between the first drying tunnel monomer 11 and the second drying tunnel monomer 12 is tighter, and the sealing performance of the air duct is improved. Moreover, the connector 14 is also provided for communicating the air duct with the accommodating chamber 311 of the tub 31, i.e., the other end of the connector 14 is fixedly connected to the tub 31, and the inside of the connector 14 is provided with an air-delivering passage 141 for communicating the air duct with the accommodating chamber 311 of the tub 31. Thus, the connection of the connector 14 is used for communicating the air duct with the accommodating cavity 311 of the drum 31, so that the hot air flow in the air duct can flow into the drum 31 to perform the drying treatment of clothes.

As shown in fig. 11 and 12, in the embodiment of the present invention, the connector 14 includes a connector body 142 and a cover 143 that are connected to each other, and the connector body 142 and the cover 143 may be connected to each other by a screw type fastener or a snap structure. Thus, a clamping force can be provided in the process of connecting the joint body 142 and the cover 143, and the clamping and fastening of the first drying tunnel monomer 11 and the second drying tunnel monomer 12 arranged between the joint body 142 and the cover 143 can be achieved. Specifically, the joint body 142 includes a connection end 1421 and a first clamping end 1422 for connecting with the first drying tunnel unit 11, where the connection end 1421 is fixedly connected with the tub 31 (refer to fig. 1); the cover 143 includes a second clamping end 1431 for connecting with the second drying tunnel 12 and a connector 1432 for connecting with the connector body 142, and a mounting notch 1423 and a fixing portion 1424 are formed on the connector body 142. The shape of the mounting notch 1423 remains substantially the same as the contour shape of the cover 143. When in assembly, the cover 143 is covered on the mounting notch 1423, the first drying tunnel unit 11 and the second drying tunnel unit 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. Thus, the cover 143 and the joint body 142 can be fixedly connected, and the first drying tunnel unit 11 and the second drying tunnel unit 12 can be clamped and fixed. The cover 143 is covered on the mounting notch 1423, and the air channel 141 is formed between the connector body 142 and the cover 143, so as to communicate the air channel with the accommodating cavity 311 of the tub 31, and to convey the hot air flow in the air channel into the accommodating cavity 311 (refer to fig. 1) of the tub 31.

As shown in fig. 11 and 12, in an embodiment of the present invention, to ensure stability of the positions of first and

second tunnel cells

11, 12 sandwiched between first and second clamping ends 1422, 1431, joint 14 is configured to further include first and second mounting

structures

1425, 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 drying tunnel unit 11 (refer to fig. 6); a second mounting structure 1433 is disposed on the second clamping end 1431, the second mounting structure 1433 being configured for attachment of a second drying tunnel cell 12. After connection, one end of each of the first and second drying

tunnel cells

11, 12 for connection to the adapter 14 is sandwiched between the first and second mounting

structures

1425, 1433. Specifically, the first mounting structure 1425 and the second mounting structure 1433 may each be in the form of a connecting slot, that is, connecting slots are formed on the first clamping end 1422 and the second clamping end 1431 respectively in a recessed manner, and the shape of the connecting slot on the first clamping end 1422 is preferably matched with the shape of one end for insertion connection on the first drying tunnel monomer 11; likewise, the shape of the attachment slot on second clamping end 1431 is preferably also matched to the shape of the end of second channel element 12 for insertion attachment. Therefore, when in connection, one ends of the first drying tunnel monomer 11 and the second drying tunnel monomer 12 which are used for connection and fixation are respectively inserted into the corresponding connecting grooves, so that assembly connection can be reliably realized, and the limiting and fixing of the connecting grooves can play a role in limiting the connection positions of the first drying tunnel monomer 11 and the second drying tunnel monomer 12. In addition, the length of the connecting groove can also limit the depth of the connection between the first drying tunnel monomer 11 and the second drying tunnel monomer 12, so that the inserted length can meet the requirement of reliable connection. Meanwhile, in order to improve the tightness after connection, a sealing piece is arranged in the connecting groove, the sealing piece is used for sealing, and the tightness after whole assembly is improved.

As shown in fig. 11 and 12, the connector 14 further includes a plug connector 144. The plug 144 is protruding on the surface of the connection end 1421 facing the barrel 31, and the plug 144 is used for being inserted into the vent hole on the barrel 31. Thus, when the connector 14 is fixedly connected with the barrel 31, the plug 144 can be inserted into the vent hole on the barrel 31, and the plug 144 and the vent hole are matched to play a role in installation and positioning, so that the convenience of installation and connection between the connector 14 and the barrel 31 is improved. Meanwhile, a flow passage 1441 communicating with the gas transmission passage 141 is provided in the plug 144, and the gas transmission passage 141 is communicated with the accommodating chamber 311 (see fig. 1) of the tub body 31 through the flow passage 1441, so that the hot air in the air duct can enter the tub body.

As shown in fig. 6 and 11, in one possible embodiment, the joint 14 further comprises a first sealing body 15. The first sealing body 15 is sandwiched between the connector 1432 and the fixing portion 1424, and is used for sealing a gap between the connector 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 connector 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 portions for sandwiching the first drying tunnel cell 11 and the second drying tunnel cell 12, and when the cover 143 and the joint body 142 are assembled and connected, the first sealing body 15 is pressed to elastically deform the first sealing body 15, so that the gap between the joint head 1432 and the fixing portion 1424 can be sealed, and the sealing performance of the gas transmission passage 141 is ensured.

As shown in fig. 6 and 11, in one possible embodiment, the joint 14 further includes a second seal 16. Specifically, along the shape of the fixing portion 1424, a mounting groove 1426 is formed in the fixing portion 1424, the second sealing body 16 is disposed in the mounting groove 1426, and the connector 1432 is pressed against the second sealing body 16. In this way, the connector 1432 can elastically deform the second sealing body 16 by pressing the second sealing body 16 through the connector 1432 during the connection with the fixing portion 1424, and further, the gap between the connector 1432 and the fixing portion 1424 can be 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 ensured that the second sealing body 16 can be kept at the sealing position without being deviated even if it is pressed, and the sealing reliability is good. In this arrangement, the second sealing body 16 and the first sealing body 15 seal the gap between the connector 1432 and the fixing portion 1424 together, so as to further improve the tightness of the gas transmission channel 141.

In one possible embodiment, the first sealing body 15 is provided to be made of sponge, and the second sealing body 16 is provided to be made of rubber or silicone or the like. Because the sponge can generate elastic deformation, compared with the sponge material, the rubber or the silica gel can generate elastic deformation with the performance slightly smaller than that of the sponge material. This is arranged such that the top surface of the first sealing body 15 is higher than the top surface of the second sealing body 16. Therefore, when the cap 143 is assembled and connected to the joint body 142, even if the height of the first sealing body 15 is higher than the height of the second sealing body 16, the first sealing body 15 can elastically deform under compression to a greater extent than the second sealing body 16, so that the first sealing body 15 under stress does not block the second sealing body 16 from elastically deforming, and both the first sealing body 15 and the second sealing body 16 can deform under compression. In this way, under the dual sealing action of the first sealing body 15 and the second sealing body 16, the sealing performance between the cover 143 and the connector body 142 is reliably improved, and the sealing performance of the gas transmission channel 141 is further ensured.

Meanwhile, since the first sealing body 15 is provided on the fixing portion 1424, the installation step can also position the installation position of the first sealing body 15 (refer to fig. 6), so that the first sealing body 15 can maintain the sealing position without being deviated even if being pressed, and reliable sealing is ensured.

As shown in fig. 13 and 14, in one possible embodiment, the volute 23 is further connected with the first drying tunnel unit 11, and a mounting portion 111 matching the shape of the blower 21 is provided on the first drying tunnel unit 11, the mounting portion 111 is used for accommodating the blower 21, the volute 23 is covered above the blower 21 and at least abuts against the mounting portion 111, so that the blower 21 can be mounted between the volute 23 and the mounting portion 111 in a sealing manner, and the volute 23 is connected with the mounting portion 111. Specifically, referring to fig. 15 and 16, a first connection part 112 is provided at the mounting part 111 of the first drying tunnel 11, a second connection part 233 is provided at the scroll casing 23, and the first connection part 112 and the second connection part 233 are stacked on each other and fixedly connected to each other by a screw-type fastener. Meanwhile, at least the first connecting piece 113 is provided on the first connecting portion 112, at least the second connecting piece 234 is provided on the second connecting portion 233, and the first connecting piece 113 and the second connecting piece 234 are connected by means of a clamping manner. Specifically, it is preferable that the first connecting portion 112 and the second connecting portion 233 are each provided in a flange structure and have substantially the same shape therebetween so as to be able to maintain the mating connection. In connection, the first connection portion 112 and the second connection portion 233 are stacked on each other, and the positions of the first connection member 113 and the second connection member 234 can be aligned, so that the first connection member 113 and the second connection member 234 can be engaged with each other. The setting like this has realized that the connection between spiral case 23 and the installation department 111 both is fixed through screw class fastener, again is fixed through the mode of mutually block between first connecting piece 113 and the second connecting piece 234, this kind of mode through screw class fastener and block connection realize being connected between spiral case 23 and the installation department 111, not only can reduce the quantity that screw class fastener set up, promote the convenience of spiral case 23 installation, simultaneously, the mode of block connection can reduce and destroy the condition of first connecting portion 112 and second connecting portion 233 structural integrity because of setting up the screw hole, and then promoted the leakproofness between spiral case 23 and the installation department 111.

As shown in fig. 6, in the embodiment of the present invention, the first connector 113 includes a first body 1131 and a first fastener 1132. The first body 1131 is disposed on the first connection part 112; the second connecting member 234 includes a second body 2341 and a second fastening member 2342, and the second body 2341 is disposed on the second connecting portion 233. Specifically, the first body 1131 is preferably configured in a plate-like structure, one end of the first body 1131 is connected to the first connecting part 112, and the other end of the first body 1131 extends upward. Similarly, the second body 2341 is preferably configured in a plate-like structure, and one end of the second body 2341 is connected to the second connection portion 233, and the other end of the second body 2341 also extends upward. While the first clasp 1132 is disposed on the first body 1131 and the second clasp 2342 is disposed on the second body 2341. The first latch 1132 and the second latch 2342 are disposed at positions required to ensure that the two can be connected. Therefore, during assembly connection, the first body 1131 and/or the second body 2341 are elastically deformed by extrusion, so that the first fastening member 1132 and the second fastening member 2342 are fastened with each other to realize connection, and the connection operation is convenient.

In actual setting, the first fastening member 1132 may be set as a fastening hook, and the second fastening member 2342 is a fastening hole; or the first fastening member 1132 is provided as a fastening hole, and the second fastening member 2342 is a fastening hook. The shape of the clamping hole is kept to be matched with that of the clamping hook, so that the clamping hook can be clamped into the clamping hole to achieve hooking, and the connection convenience is good.

In one possible embodiment, as shown in fig. 5, in order to improve the tightness of the connection between the volute 23 and the mounting portion 111, a sealing member 235 is further disposed on the volute 23, and the sealing member 235 is continuously disposed along the contour shape of the volute 23 and avoids the location of the air outlet 232. Specifically, referring to fig. 3 and 4, the upper end of the sealing member 235 is connected to the bottom of the edge of the scroll 23, and the lower end of the sealing member 235 extends downward, so that when the scroll 23 is connected to the first drying tunnel 11, the lower end of the sealing member 235 can be inserted into the mounting portion 111 of the first drying tunnel 11 and pressed against the bottom wall of the mounting portion 111. By this arrangement, the seal member 235 is provided between the scroll casing 23 and the mounting portion 111 except for the air outlet 232, and the lower end of the seal member 235 is pressed against the bottom wall of the mounting portion 111 to maintain the pressed state, so that the gap between the lower end of the seal member 235 and the bottom wall of the mounting portion 111 can be sealed, and the air leakage can be prevented. In addition, since the connection between the scroll casing 23 and the mounting portion 111 is also achieved by the first connection portion 112 and the second connection portion 233 being overlapped with each other, the overlapping between the first connection portion 112 and the second connection portion 233 also plays a role of sealing. Therefore, two structures for sealing are arranged at the connection position of the volute 23 and the mounting part 111, double-effect sealing is realized at the connection position of the volute 23 and the mounting part 111, the sealing effect is improved, and the wind generated by the fan 21 cannot leak.

In the above description, the lower end of the sealing member 235 is the end of the sealing member 235 facing the direction of the mounting portion 111, and the upper end of the sealing member 235 is the end opposite to the lower end of the sealing member 235. The second connection portion 233 is continuously disposed along the contour of the scroll case 23, and is formed in a ring shape such that an inner edge of the second connection portion 233 is vertically connected to the sidewall of the sealing member 235, and an outer edge of the second connection portion 233 extends outward for fixedly connecting with the first connection portion 112.

Specifically, the fan 21 is located in the cavity 231 of the volute 23, and wind generated by rotation of the fan 21 flows out through the air outlet 232 and into the air duct. As shown in fig. 5 and 14, in one possible embodiment, in order to enable the air in the cavity 231 to be smoothly discharged into the air duct, a volute tongue structure 236 is disposed at one end of the sealing member 235 at the air outlet 232, where the volute tongue structure 236 is used for guiding the air in the cavity 231 to be discharged in time, and preventing the discharged air from flowing back and circulating in the cavity 231, so that the air cannot be discharged, which is beneficial to improving the air discharging efficiency of the blower 21. In addition, the volute tongue structure 236 is directly formed by bending the sealing element 235, and no additional independent structural arrangement is needed, so that the convenience of setting the volute tongue structure 236 is improved, and the difficulty of manufacturing the volute 23 is reduced.

As shown in fig. 5 and 14, the volute tongue structure 236 includes a wind guide portion 2361 and a wind shielding portion 2362, one end of the wind guide portion 2361 is connected to the seal 235, and the other end of the wind guide portion 2361 is connected to the wind shielding portion 2362. Specifically, the air guide portion 2361 is bent toward the outside of the width direction of the air outlet 232, so that the air guide portion 2361 can be prevented from causing a reduction in the width of the air outlet 232, and the air inside the cavity 231 can be guided to be discharged while ensuring that the air outlet 232 has a sufficient air discharge area. The wind shielding portion 2362 has a plate-like structure and is located at a side close to the air duct. The wind shielding portion 2362 is provided to block the air flowing out from the air outlet 232 from flowing back into the cavity 231, so that the air discharged from the air outlet 232 is prevented from flowing back into the cavity 231 by the vortex generated by the blocking of the wind shielding portion 2362 after entering the air duct. In practice, the wind shielding portion 2362 is preferably inclined, so that the air outlet 232 is formed in a shape substantially as follows: the width of the air outlet 232 is gradually increased from the direction that the air flows out of the cavity 231 into the air channel, so that the air has an increasingly larger passing area in the process of flowing out through the air outlet 232, and the smoothness of the exhaust is improved.

In the above, the outer side in the width direction of the air outlet 232 means a direction in which the width of the air outlet 232 can be increased.

In one possible embodiment, the air guiding portion 2361 is provided in a circular arc shape, and the radius of the air guiding portion 2361 is made smaller than the radius of the blower 21. Specifically, the size of the shape of the wind guide 2361 affects the size of noise generated when wind flows through the wind guide 2361. Thus, in the embodiment of the present invention, the radius of the air guide 2361 is preferably set to 3% to 6% of the radius of the fan 21. In this way, the shape of the air guide portion 2361 can reduce noise while satisfying the discharge of the guide air, and the comfort of the actual use can be improved.

As shown in fig. 9 and 14, in one 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 air in the air duct, the temperature of the air heated in the air duct can be kept in a proper range, the temperature detecting element 20 is used for detecting the temperature of the air in the air duct in real time, and the temperature detecting signal can be fed back, so that the control system can control the working state of the heating element 22 according to the temperature detecting signal, and further the temperature in the air duct can be kept in a proper range. Specifically, the temperature detecting member 20 is mounted on the first drying tunnel unit 11 and/or the second drying tunnel unit 12, and in order to improve the tightness of the air duct, in the embodiment of the present invention, a mounting structure 17 that is not communicated with the interior of the air duct is provided on the first drying tunnel unit 11 and/or the second drying tunnel unit 12, and the temperature detecting member 20 is mounted in the mounting structure 17. This is provided because the mounting structure 17 does not cause the structural integrity of the first drying tunnel cell 11 and/or the second drying tunnel cell 12 to be compromised and the temperature within the tunnel can be transferred into the mounting structure 17. Therefore, the arrangement mode not only can realize the detection of the temperature in the air duct, but also ensures the tightness of the air duct, avoids the condition that the tightness of the air duct is damaged due to the arrangement of the temperature detection piece 20, meets the use requirement that the tightness of the air duct can be ensured while the temperature in the air duct is detected, and has good installation structure 17 and the temperature detection piece 20.

As shown in fig. 9 and 14, in one possible embodiment, the mounting structure 17 is configured as a mounting blind hole. The open end of the mounting blind hole faces outward (i.e., the side away from the air duct), and the temperature detecting member 20 is typically a temperature sensor. The arrangement of the mounting blind holes can play a role in reducing the wall thickness of the first drying tunnel monomer 11 and/or the second drying tunnel monomer 12, and the temperature in the air duct can be quickly transferred to the inner wall surface of the mounting blind holes through heat transfer. Thus, during installation, the temperature detecting member 20 is fixed in the installation blind hole, and the temperature detecting member 20 is tightly attached to the inner wall surface of the installation blind hole. Therefore, the temperature on the inner wall surface of the mounting blind hole can be timely detected by the temperature detecting piece 20, and the accuracy of temperature detection is improved.

In one possible embodiment, as shown in fig. 14, it is employed to project the bottom of the mounting blind hole toward the inside of the air duct. That is, the mounting blind holes arranged on the first drying tunnel monomer 11 and/or the second drying tunnel monomer 12 are protruded towards the inside of the air duct to form a bulge structure. The setting like this, the wind blows to the swell in the in-process that flows in the wind channel, and the heat of wind can be received to the swell, and the heat of receipt makes the temperature of swell structure rise to conduct to temperature detection spare 20 through heat transfer, make temperature detection spare 20 can in time detect temperature state, realize the detection to the temperature in the wind channel. In an embodiment of the present invention, mounting structure 17 is provided on second drying tunnel cell 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. Thus, in the actual setting, the difference between the actual temperature value in the air duct and the temperature value 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 may be arranged at intervals, and a temperature detecting member 20 is fixed in each mounting structure 17. Therefore, the temperature in the air duct is detected through the plurality of temperature detecting pieces 20 at the same time, and the accuracy of temperature detection in the air duct is improved in the temperature detecting mode.

As shown in fig. 1 and 17, in one possible embodiment, the first drying tunnel unit 11 is integrally formed by stamping a sheet metal part, and in order to reduce the difficulty in stamping the first drying tunnel unit 11, the overall shape of the first drying tunnel unit 11 is configured to include the mounting portion 111, the ventilation portion 114, and the bending portion 115 described above. The first drying tunnel unit 12 is connected with the ventilation part 114, so that an air channel is formed between the ventilation part 114 and the first drying tunnel unit 12; the bending part 115 is used for connecting the ventilation part 114 and the installation part 111 to form a whole, so that after the ventilation part 114 and the installation part 111 are connected through the bending part 115, the formed whole is in a ladder-shaped structure, and the shape of the whole is matched with the shape of the barrel body 31 for installing the ventilation assembly, so that the installation and fixation of the ventilation assembly can be satisfied. Specifically, the ventilation portion 114 is located above and in front of the mounting portion 111 in the direction in which the wind flows. In this way, the mounting portion 111 is submerged in comparison with the plane of the ventilation portion 114, so that the plane of the mounting portion 111 is lower than the plane of the ventilation portion 114, and the profile shape formed by connecting the ventilation portion 114, the mounting portion 111 and the bending 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. The installation requirement of the fan can be met, and when the installation part 111 is formed through sheet metal part stamping, the installation part 111 with larger stamping forming depth is not needed, so that the required stamping forming depth of the installation part 111 is reduced, the production difficulty of the installation part 111 is reduced, the convenience of machining 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.

In the above description, the plane of the ventilation part 114, the mounting part 111 and the bending part 115 refers to the plane of the first drying tunnel 11 contacting with the second drying tunnel 12 or the volute 23.

In one possible embodiment, as shown in fig. 1 and 17, the bent portion 115 may be provided in an "inclined" or "horizontal" shape, depending on the 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 ventilation assembly is so formed that its shape can be matched with the shape of the mounting position on the tub body 31, and when mounted, the ventilation part 114 and the mounting part 111 can be kept substantially in contact with the mounting position on the tub body 31, so that the mounting is facilitated, and the reliability and convenience after the mounting are improved.
