Meanwhile, connecting edges are respectively arranged on the two sides of the first drying channel single body 11 and the second drying channel single body 12 along the length direction, when the two connecting edges are connected, the connecting edges on the two sides of the first drying channel single body 11 and the connecting edges on the two sides of the second drying channel single body 12 are correspondingly overlapped, and then the two connecting edges are fixed through screw fasteners or other modes, so that the connection between the first drying channel single body 11 and the second drying channel single body 12 is realized.

As shown in fig. 8, in the embodiment of the present invention, in order to improve the sealing performance after the first drying tunnel single body 11 and the second drying tunnel single body 12 are connected, so that the hot air flowing in the air duct does not leak, a sealing structure 18 is further disposed at the connection position of the first drying tunnel single body 11 and the second drying tunnel 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 drying tunnel single body 11 and the second drying tunnel single body 12, and the sealing structure 18 seals the gap between the connecting edges which are overlapped with each other, thereby playing the role of improving the air duct sealing performance.

Specifically, as shown in fig. 7 to 9, 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.

In one possible embodiment, the joint 14 further includes a second sealing body 16, as shown in fig. 5 and 14. Specifically, along the shape of the fixing portion 1424, a mounting groove 1426 is formed on 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.

Specifically, the fan 21 is located in the cavity 231 of the volute 23, and the wind generated by the rotation of the fan 21 flows out through the wind outlet 232 and enters the wind channel. As shown in fig. 4 and 5, in one possible embodiment, in order to enable the wind in the cavity 231 to be smoothly discharged into the wind channel, a volute tongue structure 236 is disposed at an end of the sealing member 235 at the wind outlet 232, and the volute tongue structure 236 is used to guide the wind in the cavity 231 to be discharged in time, and can prevent the discharged wind from flowing back and circulating in the cavity 231, which results in the situation that the wind cannot be discharged, and is beneficial to improving the exhaust efficiency of the fan 21. Moreover, the volute tongue structure 236 is formed by bending the sealing element 235 directly, and additional independent structure setting is not needed, so that the convenience of setting the volute tongue structure 236 is improved, and the difficulty of producing and manufacturing the volute 23 is reduced.

As shown in fig. 4, the volute tongue structure 236 includes a wind guide portion 2361 and a wind blocking portion 2362, one end of the wind guide portion 2361 is connected to the sealing member 235, and the other end of the wind guide portion 2361 is connected to the wind blocking portion 2362. Specifically, the air guide portion 2361 is bent toward the outside in the width direction of the air outlet 232, so that the air guide portion 2361 can be prevented from reducing the width of the air outlet 232, and the air outlet 232 can be ensured to have a sufficient air discharge area and the air inside the cavity 231 can be guided to be discharged. The wind blocking portion 2362 is a plate-shaped structure and is located at a side close to the wind passage. This wind-break portion 2362 sets up and is used for blockking the wind that flows out by air outlet 232 to flow back to in the cavity 231, makes from air outlet 232 exhaust wind after getting into the wind channel, through the blockking of wind-break portion 2362, can avoid the wind of high-speed flow to take place the swirl and flow back to in the cavity 231. In actual installation, the wind shielding portion 2362 is preferably disposed in an inclined manner, so that the shape of the air outlet 232 is substantially as follows: from the direction that wind flows out to the wind channel in by cavity 231, the width crescent of air outlet 232 to wind has bigger and bigger area of passing through at the in-process that air outlet 232 flows out, has promoted exhaust smoothness and easy nature.

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

In a possible embodiment, the wind guide portion 2361 is formed in an arc shape, and the radius of the wind guide portion 2361 is smaller than the radius of the fan 21. Specifically, the size of the shape of the wind guide portion 2361 affects the amount of noise generated when wind flows through the wind guide portion 2361. Therefore, in the embodiment of the present invention, the radius of the air guide portion 2361 is preferably set to 3% to 6% of the radius of the fan 21. Thus, the shape of the air guide portion 2361 can reduce noise while satisfying the discharge of the guide air, and improve the comfort in actual use.

As shown in fig. 5 and 6, 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 drying tunnel single body 11 and/or the second drying tunnel single body 12, and in order to improve the sealing performance of the air duct, referring to fig. 16, 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 drying tunnel single body 11 and/or the second drying tunnel single body 12, and the temperature detecting member 20 is mounted in the mounting structure 17. This is so arranged that the structural integrity of the first drying tunnel unit 11 and/or the second drying tunnel unit 12 is not damaged by the mounting structure 17, and the temperature in the air duct can be transferred 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 ingeniously.

In one possible embodiment, the mounting structure 17 is configured as a blind mounting hole, as shown in fig. 15 and 16. 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 drying tunnel single body 11 and/or the second drying tunnel 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. 6 and 16, in the embodiment of the present invention, it is adopted that the bottom of the blind mounting hole is projected toward the inside of the air duct. Namely, the blind installation holes arranged on the first drying tunnel single body 11 and/or the second drying tunnel single body 12 protrude towards 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 embodiment of the present invention, the mounting structure 17 is disposed on the second drying tunnel 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.

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 the connection 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. Set up like this, not only can satisfy the installation demand of fan, when through sheet metal component stamping forming installation department 111, need not the great installation department 111 of stamping forming degree of depth moreover, reduced the required stamping forming's of installation department 111 degree of depth, make the production degree of difficulty of installation department 111 obtain reducing, improved machine-shaping's convenience, also can prevent that installation department 111 from producing the fold, make the internal face keep for the planomum, promoted ventilation performance.
