It is provided to supply air to the space formed in , and the second supply port 219b may be provided to supply air to the space formed between the fourth heating element 914 and the second heating element 912.

As shown in FIG. 2, since the drying chamber 211 provided in the present invention is provided with an inlet 211a on the upper surface, the air that has completed heat exchange with the clothes enters the cabinet 1 through the inlet 211a. Some of the air discharged inside the cabinet (1) is discharged to the outside of the cabinet (1) through the entrance (131), etc., and the rest is discharged to the drying chamber (211) through the air supply unit (4). ) is resupplied.

Although the air discharged from the inlet 211a is air that has completed heat exchange with clothing, it is air that possesses thermal energy compared to the outside air flowing in through the cover through hole 151. Therefore, in the present invention, the air supply unit 4 resupplies some of the air discharged through the inlet 211a to the drying chamber 211, which has the effect of saving energy required for drying (clothes with high drying efficiency). There is an effect of providing a processing device).

For this purpose, the amount of air discharged from the drying chamber 211 and supplied to the air supply unit 4 is set to be greater than the amount of air supplied to the air supply unit 4 through the cover through hole 151. desirable. According to the experiment, the ratio of the amount of air discharged from the drying chamber 211 and supplied to the air supply unit 4 and the air supplied to the air supply unit 4 through the cover through hole 151 is 60:40. The drying efficiency is the best when set to 55:45.

The amount of air discharged from the drying chamber 211 and supplied to the air supply unit 4 and the amount of air supplied to the air supply unit 4 through the cover through hole 151 are determined by the area of the inlet 211a, Through the total area of the cover through hole 151, the area of the first inlet 431a, the second inlet 432a, the area of the first supply port 219a, and the area of the second supply port 219b. It is adjustable.

The first side guide 718a and the second side guide 719a are provided to extend from both ends of the slot 716a toward the rear frame 717. Therefore, the first side guide 718a provides a space where one side of the mesh frame body 771 is accommodated, and the second side guide 719a provides a space where the other side of the mesh frame body 771 is accommodated. We will provide a space where

The length L1 of the front frame with respect to the direction in which the mesh frame 77 is inserted (-Z-axis direction) is the front frame of the mesh frame with respect to the direction in which the mesh frame 77 is inserted (-Z-axis direction). It is desirable to set it longer than the direction length (ML1). In addition, the depth of the first side guide 718a facing away from the second side frame 719 (-X axis direction) is the side width (ML4, mesh frame first side) of the mesh frame body 771. The depth (L2) of the second side guide 719a is set longer than the width of the first side frame 718 and faces away from the first side frame 718 (X-axis direction). The depth L2 is the side width of the mesh frame body 771. It is desirable to set it longer than (ML2, width of the second side of the mesh frame). This is to minimize exposure of the film FR formed on the first mesh 76 to the outside.

The rear guide 717a is a means of providing a space into which the rear surface of the mesh frame body 771 is inserted. The rear guide 717a is designed to move the surface of the rear frame 717 away from the front frame 716. It may be provided as a groove bent concavely in the direction (-Z axis direction), or may be provided as a rear frame through hole (see FIG. 9) provided to penetrate the rear frame 717.

In any case, the length L3 of the rear guide in the direction in which the mesh frame 77 is inserted is longer than the rear surface length ML3 of the mesh frame body 771 in the direction in which the mesh frame is inserted. must be set.

In order to prevent the first mesh 76 from sagging, the first rack frame F1 may be provided with a plurality of mesh supports 713 connecting the front frame 716 and the rear frame 717.

As shown in FIG. 7, the lower surface of the front frame 716 is provided with an insulating part insertion groove 715 to which the insulating part 79 is fixed, and the upper surface of the front frame 716 is provided with a handle 724. ) may be provided.

The first side frame 718 and the second side frame 719 include a first axis fastening part (not shown) to which the first rack first axis 215a is detachably coupled, and a first rack second axis 216a. ) are each provided with a second shaft fastening portion 78 that is detachably coupled. The first side frame 718 is provided with a first bent portion 751 bent in a direction (X-axis direction) away from the first side 215 of the drying chamber, and the second side frame 719 is provided with a first bent portion 751. A second bent portion 753 is provided that is bent in a direction away from the second side 216 of the drying chamber (-X axis direction). Since the shapes and functions of the first shaft fastening portion, the second shaft fastening portion 78, the first bending portion 751, and the second bending portion 753 have been previously described, detailed descriptions will be omitted.

The present invention can be modified and implemented in various forms, and its scope is not limited to the above-described embodiments. Therefore, if the modified embodiment includes elements of the claims of the present invention, it should be considered to fall within the scope of the present invention.
