DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clothes dryer.

[0002]

2. Description of the Related Art As a clothes drying system, a combination of a rotary dryer and a cabinet dryer having a heat source independently in a unit shape is known.

[0003]

However, in this known example, since the cabinet type dryer is also provided with its own heat source, the heat cost is high and the equipment is troublesome and expensive.

Further, since the exhaust pipes coming out of both the rotary dryer and the cabinet dryer cannot be joined on the way, each of them needs its own exhaust pipe, and it is difficult to construct two pipes. After the building has been constructed, construction may not be possible.

An object of the present invention is to provide a clothes dryer having a rotary type and a cabinet type function which is energy saving type and can be easily installed.

[0006]

The clothes dryer according to the present invention is as follows.

[0007] A partition wall is provided in the casing to form a rotary drying unit with a heating source on one side and a static drying chamber without a heating source on the other side. The structure is such that the gas is introduced into the stationary drying chamber via the first exhaust passage in the casing, and an exhaust port is provided in an upper portion of the static drying chamber, and the exhaust port and the exhaust duct outside the casing are connected to the second exhaust port. Connecting the first exhaust passage to the second exhaust passage in the casing; and branching the first exhaust passage and the bypass exhaust passage. A first switching damper is incorporated in the section, and a second switching damper is attached to the junction of the second exhaust passage and the bypass passage. , A. When only the rotary drying section is used, the first switching damper and the second switching damper are operated to discharge the exhaust of the rotary drying section to the outside of the casing via the bypass exhaust passage, b. When both the rotary drying section and the still drying chamber are used at the same time, the exhaust gas discharged from the rotary drying section is introduced into the still drying chamber via the first exhaust passage, and the exhaust gas from the still drying chamber is exhausted. Through the second exhaust passage to the outside of the casing, c. When only the stationary drying chamber is used, the rotary drying unit is operated to introduce the exhaust gas from the first exhaust passage into the stationary drying chamber, and the exhaust gas in the stationary drying chamber is discharged from the second exhaust passage to the outside of the casing. A clothes dryer characterized by discharging.

[0008]

The rotary drying section has its own heating source, and can be dried independently by putting clothes in the rotary drum. on the other hand,
Since there is no heat source in the static drying room, drying operation cannot be performed independently. Therefore, the following drying mode is controlled by the controller.

A. When only the rotary drying section is used, the first switching damper and the second switching damper are operated to discharge the exhaust of the rotary drying section to the outside of the casing via the bypass exhaust passage, b. When both the rotary drying section and the static drying chamber are used at the same time, the exhaust gas discharged from the rotary drying section is introduced into the static drying chamber via the first exhaust passage, and the exhaust gas from the static drying chamber is exhausted. Through the second exhaust passage to the outside of the casing, c. When only the static drying chamber is used, the rotary drying section is operated to introduce the exhaust gas from the first exhaust passage into the static drying chamber, and the exhaust gas in the static drying chamber is passed through the second exhaust passage. Discharge outside the casing.

[0010] When a stationary drying chamber is used,
When the drying is sufficiently performed, the damper may be switched to exhaust air to the outside of the casing via the bypass exhaust passage, and an overdrying prevention control function not introduced to the stationary drying chamber may be added. The state of drying in the still drying chamber can be detected by a humidity sensor, a temperature sensor, or the like mounted in the second exhaust passage. Alternatively, it is also possible to set a time (timer) at the time of use.

1 shows a clothes dryer according to the present invention. 1 is a casing made of a heat-resistant material in a closed structure, 2
Is a partition wall vertically partitioning the inside of the casing 1, a tall stationary drying chamber 3 is formed on the left side, and a rotary dryer (part) 4 having a heating source is incorporated on the right side. Have been.

Reference numeral 5 denotes a first exhaust passage connecting an exhaust port 4 'of the rotary dryer 4 and an inlet 5' formed in the lower part of the still drying chamber 3, and 6 denotes an exhaust gas formed in the upper part of the still drying chamber 3. A second exhaust passage connecting the port 7 and the exhaust duct 8 outside the casing 1, a bypass exhaust passage 9 connecting the first exhaust passage 5 and the second exhaust passage 6, and a branch portion of the bypass exhaust passage 9. The switching damper 11 mounted on the second exhaust passage 6
And a switching damper 12 attached to the junction of the bypass exhaust passage 9 as a controller to perform the following control.

A. When only the rotary dryer 4 is used, the first switching damper 10 and the second switching damper 11
To exhaust the exhaust air of the rotary dryer 4 from the casing 1 to the outside via the exhaust duct 8 via the bypass exhaust passage 9.

B. When both the rotary dryer 4 and the stationary drying chamber 3 are used at the same time, the exhausts discharged from the rotary dryer 4 are operated via the first exhaust passage 5 by operating the dampers 10 and 11. The air is introduced into the still drying chamber 3, and the exhaust air from the still drying chamber 3 is discharged from the casing 1 via the second exhaust passage 6 to the outside via the exhaust duct 8. This situation is shown in FIG.

C. When only the stationary drying chamber 3 is used, the rotary dryer 4 is operated to introduce the exhaust gas from the first exhaust passage 5 into the stationary drying chamber 3. (2) The air is discharged outside from the exhaust passage 6 via the exhaust duct 8 outside the casing 1.

In the figure, reference numeral 13 denotes a washing machine.

[0017]

As described above, the present invention incorporates a rotary dryer in a casing, introduces exhaust gas discharged from the rotary dryer into a stationary drying chamber, and puts the clothes placed in the stationary drying chamber. No heat source is required on the stationary drying chamber side to dry the components. For this reason, an energy-saving type clothes dryer can be constructed. In addition, since it is only necessary to extend one exhaust pipe from the casing to the outside, there is no need to attach two exhaust pipes as in the conventional case, which can reduce equipment costs, construction work, and problems in building strength. Is also gone.
