Description

[Detailed Description of the Invention] The present invention achieves a uniform temperature distribution in drying clothes by blowing air heated in a heating chamber into a drying chamber.

Reference numeral 1 denotes a clothes dryer main body which has a door 2 for loading clothes on the front and an intake port 3 at the upper part of the back, and the inside of the main body is divided into a heating chamber 5 and a drying chamber 6 through a partition plate 4. ing.

7 is a rotating drum installed in the drying chamber 6, which has a large number of ventilation holes 8, 8... in the peripheral wall and a clothes input port 9 in the front.
A drive shaft 10 protrudes from the rear surface of the drilled waist and is connected to a motor 12 via a pulley 11 and the like.

Reference numeral 13 denotes an exhaust side filter provided in the drying chamber, and is obliquely attached to the lower side of a ceiling plate 16 extending from a blower casing 15 in which a blower 14 is installed.

The reason why this filter is attached to the lower side of the ceiling plate 16 is to prevent buttons etc. from falling from clothing from directly hitting the filter 13, and also to prevent unnecessary lint from falling onto the filter. This is to prevent such things from adhering.

Further, the partition plate 4 is provided with an air outlet 17 for sucking the air heated in the heating chamber 5 into the drying chamber 6.
A burner 18 is provided inside the heating chamber 5 along one side edge of the air outlet 17 .

Reference numeral 19 denotes a cover that covers the hot air outlet 17 and the burner 18, and cold air holes 20° 21 are perforated in both side walls, respectively.

A vertical wall 22 is formed between the outlet 17 and the burner 18, and a hot air volume 23 is formed between the upper edge of the vertical wall and the inner surface of the cover 19.

In the above configuration, when the burner 18 is ignited and the motor 12 is rotated, the rotating drum 7 and the blower 14 are rotated.

When the blower 14 rotates, air is taken into the heating chamber 5 through the intake port 3, and the air enters the cover 19 through the cold air inlet 20.21.

Air entering from one cold air outlet 21 is heated by the burner 18, becomes high temperature, and flows from the hot air outlet 23 to the outlet 17.

The air entering from the other cold air outlet 20 is not heated by the burner 18 and directly goes to the outlet 17, where it mixes with the hot air and reaches an appropriate temperature, and is then transferred to the drying chamber 6.
It squirts inside.

The air at an appropriate temperature blown into the drying chamber enters the rotating drum 7 through the ventilation holes 8, dries the clothes in this drum, exits the rotating drum again, passes through the exhaust side filter 13, and enters the blower 14. It is sucked in and discharged from the discharge port 24.

Since the filter 13 is provided below the ceiling plate 16, the air leaving the rotating drum 7 goes around the suction part 25 formed at the tip of the ceiling plate 16 and enters the filter 13. The air is sucked in, and the air flow is biased toward the suction portion 25 side.

As a result, the amount of air flowing through the burner 18 is large on the side A near the suction section 25 and small on the side B far from the suction section. The temperature becomes high and the temperature distribution becomes uneven, resulting in uneven drying of the clothes in the rotating drum 7.

In order to correct such uneven temperature distribution, this proposal
Of the pair of cold air inlets 20, 21, the cold air inlet 20 and the hot air inlet 23, which are farther from the burner 18, are made uneven in vertical width.

That is, the cold air inlet 20 has a vertical dimension C on the side closer to the suction part 25 of the exhaust side filter made small and the vertical dimension d on the far side larger. is made large, and the vertical dimension f on the far side is made small.

As a result, on the side closer to the suction part 25, the amount of air passing through the cold air population 20 is small and the amount of air passing through the hot air population 23 is large, so the temperature when mixed becomes high, correcting the tendency for the temperature to become low. can do.

On the other hand, on the side far from the suction part 25, the amount of air passing through the cold air inlet 20 is large and the amount of air passing through the hot air population 23 is small, so the temperature when both are mixed tends to be low and the temperature tends to be high. can be corrected.

As described above, the present invention reduces the amount of cold air blown out or increases the amount of hot air blown out on the side closer to the suction part.
Even if the air flow is uneven, the temperature distribution can be made uniform, and clothes can be dried evenly, which is a practical effect.
