 Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The dryer 1 is provided with an outer box 2, a drying chamber 3 for accommodating clothes 8 contained in the outer box 2, and an air circulation device 4 for circulating heated air through the drying chamber 3. The outer shape of the outer box 2 has a substantially rectangular parallelepiped shape, and is formed so that a plurality of units can be installed in close contact in the lateral direction. Above the front wall 31 of the outer box 2, a timer 21 for individually setting the drying time of the clothes 8 stored in the drying chamber 3 and an end lamp 22 for displaying the end of the drying time are provided. Is provided.

The drying chamber 3 has a front wall 31 also serving as an outer wall of the outer box body 2, and has an opening 32 in the front wall 31 that opens a substantially upper half portion. The upper edge of the opening 32 reaches the lower edge of the front wall 31 of the outer box 2, and the lower edge is located substantially at the center of the front wall 31 in the height direction. On the other hand, the lower half of the front wall 31 is closed so that the circulated heated air can easily return to the air circulation device 4. In the drying room 3, a hanger bar 33 is suspended substantially at the center in the depth direction between the inner surfaces so that a plurality of clothes 8 are suspended inside.

The hanger bar 33 has cutouts 33a formed on the upper surface thereof at predetermined pitches for engaging with hangers 33b for hanging the garments 8. The above-described timer 21 and end lamp 22 are provided corresponding to the position of the notch 33a, so that the drying time of the garment 8 can be easily checked. As described above, since the notch 33a is provided at the predetermined pitch in the hanger bar 33, a gap is formed between the clothes 8 suspended from the clothes 8 in the depth direction with the left and right facing each other. The heated air sent from the garment 4 is evenly circulated, and the clothes 8 are dried efficiently.

An air circulating device 4 for circulating the heated air to the drying chamber 3 includes a heated air outlet 54 opened on the ceiling wall 34 of the drying chamber 3 and heated air opened on the floor 36 of the drying chamber 3. A ventilation path 5 having a suction port 36a, a heating device 6 for heating heated air sent from the ventilation path 5 to the drying chamber 3, and a blower 7 for blowing air into the drying chamber 3 and the ventilation path 5. Is provided. The heating device 6 has a heating element and a control section for controlling the heating value of the heating element. The heating device 6 can automatically adjust the heating value so that the atmosphere in the drying chamber 3 has a constant temperature. It is configured in. The blower 7 is installed at the intersection of a vertical passage 51 and a lower horizontal passage 53 constituting a blower passage 5 to be described later, and blows air from the lower side of the vertical passage upward. The blower 7 has, for example, a configuration including a motor and a fan that is driven to rotate by the motor, and a fan widely known in this field can be used. Further, the blower 7 controls the heated air blown out from the blowout port 54 so as to have a flow rate and a wind pressure functioning as an air curtain described later.

The air passage 5 includes a vertical passage 51 provided outside the rear wall 35 of the drying chamber 3, that is, between the outer box 2, and an upper end of the vertical passage 51 extending outside the ceiling wall 34 of the drying chamber 3. The upper horizontal passage 52 is provided between the outer casing 2 and the outlet 54 and communicates with the outlet 54. The outer casing 2 extends along the outside of the floor 36 of the drying chamber 3 from the lower end of the vertical passage 51. And a lower horizontal passage 53 communicating with the suction port 55. The outlet 54 has a long opening on the left and right sides, and is provided in a plurality substantially in parallel with the front wall 31. Therefore, the heated air flowing out of each outlet 54 circulates so as to be substantially orthogonal to the left and right sides of the suspended garment 8. The suction port 55 is open substantially over the entire floor surface 36 and is closed by a protective net 55a on a mesh such as a punched metal so as to allow ventilation.

The vertical passage 51 constituting the air passage 5 is provided at upper and lower suction openings 51 a and 51 b for selectively taking in outside air, and at a position below the lower suction opening 51 b, and circulating heating is provided. A heating device 6 is provided at an intermediate position between the upper suction opening 51a and the lower suction opening 51b, which has an exhaust opening 51c for discharging air to the outside. Each of the upper and lower suction openings 51a and 51b and the exhaust opening 51c has a lid 51d that can be opened and closed. The lids 51d of the upper and lower suction openings 51a, 51b open and close upward, so that the air sent from the blower 7 is not discharged to the outside, and the cross-sectional area of the ventilation path 5 is increased by the open lid. As a result, the air flow passing through the portion becomes faster, and the outside air efficiently flows into the vertical passage 51 from the upper and lower suction openings 51a and 51b. The outside air is introduced from the upper suction opening 51a in order to reduce the change in the texture due to drying when the clothes 8 are dried. The lid 51d of the exhaust opening 51c opens and closes downward, so that part of the air sent from the blower 7 is guided to the lid 51d and discharged to the outside. By adjusting the opening angle of the lid 51d, the amount of air to be discharged can be adjusted.

The upper lateral passage 52 has a blow guide wall 52a that is inclined downward at a front end thereof. The blow guide wall 52a is inclined so as to cover the front outlet 54, and guides the heated air sent from the rear of the upper horizontal passage 52 to the front outlet 54. Therefore, the heated air blown out from the front blowout port 54 blows downward near the inside of the opening 32.

In such a configuration, the clothes 8 to be dried are hung on the hanger 33 b, carried into the drying chamber 3 from the opening 32, and hung from the respective cutouts 33 a of the hanger bar 33. The clothes 8 to be dried may be prepared by mixing thick and thin clothes. Next, a drying time suitable for each garment is set by the timer 21 at a position corresponding to the position where the garment 8 is suspended. Then, when the heating device 6 and the blower 7 are energized, an airflow is generated in the blower passage 5 as shown by an arrow in FIG. Thus, the outside air sucked from the lower suction opening 51b is heated by the heating device 6, and the heated air mixed with the outside air sucked from the upper suction opening 51a flows into the drying chamber 3. I do. The heated air that has flowed into the drying chamber 3 reaches the floor 36 through the surroundings of the garment 8, and is sucked through the suction port 55 of the floor 36 in a state of containing moisture, and flows from the lower horizontal passage 53 to the blower 7. Circulate. A part of the heated air containing moisture is discharged to the outside from the exhaust opening 51c, sent to the blower 7 and reaches the heating device 6, where it is heated and dried. In this manner, the heated air circulates through the drying chamber 3 through the air passage 5 to dry the clothes 8.

Since the heated air exits from the outlet 54 of the ceiling wall 34 of the drying chamber 3, it functions as an air curtain for the opening 32 of the front wall 31. That is, since the heated air flows from the upper side to the lower side of the drying chamber 3 at a predetermined wind pressure and speed, the inside near the opening 32 has a lower pressure than the outside of the dryer 1. Therefore, heated air does not leak from the drying chamber 3 to the outside through the opening 32. Therefore, even though the opening 32 is provided, the drying chamber 3 is equivalent to the case where the drying chamber 3 is sealed, and the temperature in the drying chamber 3 does not decrease and is always kept at a temperature suitable for drying the clothes 8, so that the efficiency is improved. The clothes 8 can be dried well. In addition, since the opening 32 is provided, the user can touch the clothes at a desired time during the drying operation to know the degree of drying of the clothes 8 and prevent overdrying by the timer.

The present invention is not limited to the embodiment described above. In the above-described embodiment, the heating device including the infrared heater has been described. However, the heating device includes a heating element using a medium such as a dichrome wire, a semiconductor heating element, a ceramic heater, or heating steam. Is also good. In addition, the configuration of each unit is not limited to the illustrated example, and various modifications can be made without departing from the spirit of the present invention.
