[0042] The following is in conjunction with the appendix Figure 1-3 The drying unit of this utility model is described in an embodiment.

[0043] The drying unit of this utility model embodiment includes a first housing 1 and an infrared drying unit 2.

[0044] like Figure 1-3 As shown, the first housing 1 has a hot air channel 101 and an air inlet 102 and an air outlet 103 connected to the hot air channel 101. The infrared drying unit 2 is disposed in the hot air channel 101. The infrared drying unit 2 includes a second housing 4. A part of the second housing 4 is connected to the wall of the hot air channel 101, and another part of the second housing 4 is spaced apart from the wall of the hot air channel 101 to define the air outlet 103 connected to the hot air channel 101.

[0045] The second housing 4 has a heating window 405 on the side facing outward, and an infrared heating plate 13 is provided inside the second housing 4. The heating window 405 is located at the heating window 405.

[0046] The drying unit of this utility model embodiment is equipped with an infrared drying unit 2 at the air outlet 103 of the hot air channel 101. This allows the drying unit to heat and dry the material by blowing out hot air, and also to heat and dry the material by using infrared light emitted by the infrared heating plate 13. The combination of hot air heating and infrared heating enriches the heating method of the drying unit of this utility model embodiment, and also greatly improves the heating efficiency of the drying unit of this utility model embodiment.

[0047] Therefore, the drying unit of this utility model embodiment has the characteristics of rich heating methods and high heating efficiency.

[0048] In some embodiments, a filter plate 3 is provided in the hot air channel 101, and the filter plate 3 is provided with a plurality of filter holes 301. The filter plate 3 is located upstream of the infrared drying unit 2.

[0049] The drying unit of this utility model embodiment can filter the hot air flowing in the hot air channel 101 by setting a filter plate 3 in the hot air channel 101.

[0050] In some embodiments, the first housing 1 is a rectangular structure, that is, the first housing 1 itself has length, width, and height, such as... Figure 3 As shown, the hot air channel 101 extends in its height direction, the air inlet 102 is located at the upper end of the first housing 1, and the air outlet 103 is located at the lower end of the second housing 4.

[0051] It is understandable that the height direction of the first housing 1 can be vertical. Hot air enters the hot air channel 101 through the air inlet 102 located at the upper end of the first housing 1, and after being filtered by the filter plate 3, it is discharged from the air outlet 103 located at the lower end of the first housing 1.

[0052] In some embodiments, the second housing 4 has a first end 401 and a second end 402 opposite to each other in the length direction of the first housing 1, and both the first end 401 and the second end 402 are connected to the inner wall of the hot air channel 101.

[0053] The second housing 4 also has a third end 403 and a fourth end 404 opposite each other in the width direction of the first housing 1, at least one of the third end 403 and the fourth end 404 being spaced apart from the wall of the hot air passage 101 to define an air outlet 103.

[0054] For example, the third end 403 of the second housing 4 is spaced apart from the wall of the hot air channel 101, defining the air outlet 103;

[0055] For example, the fourth end 404 of the second housing 4 is spaced apart from the wall of the hot air channel 101, defining the air outlet 103;

[0056] For example, the third end 403 and the fourth end 404 of the second housing 4 are spaced apart from the wall of the hot air channel 101, defining two air outlets 103.

[0057] In some embodiments, as shown in the figure, the lower edge of the third end 403 has a first guide portion 5 extending downward and outward, and a first bending portion 7 corresponding to the first guide portion 5 in the first housing 1, the first bending portion 7 extending downward and outward; and / or,

[0058] The lower edge of the fourth end 404 has a second guide portion 6 that extends downward and outward, and the lower edge of the first housing 1 corresponding to the second guide portion 6 has a second bend portion 8 that extends downward and outward.

[0059] For example, the lower edge of the third end 403 has a first guide portion 5 that extends downward and outward, and a first bending portion 7 corresponding to the first guide portion 5 in the first housing 1. The first bending portion 7 extends downward and outward, and the first guide portion 5 and the first bending portion 7 define an air outlet 103.

[0060] For example, the lower edge of the fourth end 404 has a second guide portion 6 that extends downward and outward, and the lower edge of the first housing 1 corresponding to the second guide portion 6 has a second bend portion 8 that extends downward and outward. The second guide portion 6 and the second bend portion 8 define an air outlet 103.

[0061] For example, the lower edge of the third end 403 has a first guide portion 5 that extends downward and outward, and the first housing 1 has a first bending portion 7 corresponding to the first guide portion 5. The first bending portion 7 extends downward and outward, and the lower edge of the fourth end 404 has a second guide portion 6 that extends downward and outward. The lower edge of the first housing 1 has a second bending portion 8 corresponding to the second guide portion 6. The second bending portion 8 extends downward and outward, and the first guide portion 5, the first bending portion 7, the second guide portion 6, and the second bending portion 8 all define an air outlet 103.

[0062] Understandably, as mentioned above,

[0063] When the third end 403 of the second housing 4 is spaced apart from the wall of the hot air channel 101, the lower edge of the third end 403 has a first guide portion 5 that extends downward and outward, and a first bending portion 7 corresponding to the first guide portion 5 of the first housing 1. The first bending portion 7 extends downward and outward, and the first guide portion 5 and the first bending portion 7 define the air outlet 103.

[0064] When the fourth end 404 of the second housing 4 is spaced apart from the wall of the hot air channel 101, the lower edge of the fourth end 404 has a second guide portion 6 that extends downward and outward, and the lower edge of the first housing 1 corresponding to the second guide portion 6 has a second bending portion 8 that extends downward and outward. The second guide portion 6 and the second bending portion 8 define the air outlet 103.

[0065] When the third end 403 and the fourth end 404 of the second housing 4 are both spaced apart from the wall of the hot air channel 101, the lower edge of the third end 403 has a first guide portion 5 that extends downward and outward, the first housing 1 has a first bending portion 7 corresponding to the first guide portion 5, the first bending portion 7 extends downward and outward, the lower edge of the fourth end 404 has a second guide portion 6 that extends downward and outward, the lower edge of the first housing 1 corresponding to the second guide portion 6 has a second bending portion 8, the second bending portion 8 extends downward and outward, and the first guide portion 5, the first bending portion 7, the second guide portion 6, and the second bending portion 8 all define an air outlet 103.

[0066] In other words, when the third end 403 and the fourth end 404 of the second housing 4 are spaced apart from the wall of the hot air channel 101, the air outlet 103 defined by the first guide portion 5, the first bending portion 7, the second guide portion 6, and the second bending portion 8 forms an outward V-shaped structure.

[0067] In some embodiments, the air outlet 103 is provided with a connector 9, one end of which is connected to the second housing 4, and the other end of which is connected to the first housing 1.

[0068] Furthermore, there are multiple connectors 9, which are spaced apart along the length of the first housing 1.

[0069] The drying unit of this utility model embodiment, by providing multiple connectors 9, can better fix the second housing 4 inside the hot air channel 101 of the first housing 1, thereby greatly improving the structural stability of the drying unit of this utility model embodiment.

[0070] In some embodiments, an infrared reflector 12 is provided inside the second housing 4, and the infrared reflector 12 is disposed on the inner wall of the second housing 4.

[0071] Specifically, such as Figure 3 As shown, in the vertical direction, that is, in the height direction of the first housing 1, the infrared reflector 12 can be set on the top wall of the second housing 4. Similarly, it can be understood that, in order to simplify the structure, the infrared reflector 12 can be used as the top plate of the second housing 4, so that there is no need to set up extra structural components.

[0072] It is understandable that the infrared reflector 12 can reflect infrared rays, thereby enabling the infrared heating plate 13 to emit infrared rays in one direction and improving the infrared emission efficiency of the infrared emitting plate.

[0073] In some embodiments, at least one of the first end 401 and the second end 402 is provided with a first observation port 10, and the first housing 1 is provided with a second observation port 11 corresponding to the first observation port 10 and connected to the first observation port 10, so as to facilitate observation of the working status of the infrared heating plate 13.

[0074] It is understood that a first observation port 10 can be provided at the first end 401 of the second housing 4, or a second observation port 11 can be provided at the second end 402 of the second housing 4. Similarly, a first observation port 10 can be provided at both the first end 401 and the second end 402 of the second housing 4.

[0075] In other words, the specific settings can be configured according to actual needs.

[0076] This utility model also provides an oven.

[0077] The oven of this utility model embodiment includes the drying unit of the above embodiment.

[0078] The oven of this utility model embodiment is equipped with an infrared drying unit 2 at the air outlet 103 of the hot air channel 101 of the drying unit. This allows the drying unit to heat and dry the material by blowing out hot air, and also to heat and dry the material by using infrared light emitted by the infrared heating plate 13. The combination of hot air heating and infrared heating enriches the heating method of the oven of this utility model embodiment, and also greatly improves the heating efficiency of the oven of this utility model embodiment.

[0079] Therefore, the oven of this utility model embodiment has the characteristics of rich heating methods and high heating efficiency.

[0080] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
