Description

DETAILED DESCRIPTION OF THE INVENTION The invention relates to the structure of a conventional example of household clothing, which is equipped with a rotatably equipped drum and which dries the clothes in the drum using hot air, and its problems. In a clothes dryer, the rotation speed of the motor that rotates the drum that houses the clothes and the fan that blows hot air is always constant and does not change, regardless of the amount of clothes to be dried. Ta. However, with this configuration, it cannot be said that optimal drying can be performed depending on the amount of cloth. For example, when there is little fabric flow, a piece of clothing will stick to the wall of the drum, making it difficult for the fabric to wrap around the drum, making it difficult to dry the clothing, and causing large energy losses.

OBJECTS OF THE INVENTION An object of the invention is to provide a clothes dryer that overcomes these conventional problems and can perform efficient drying even when operating at a small capacity.

Structure of the Invention The uninvented clothes dryer includes a drum that accommodates clothes and rotates, a fan that blows hot air for drying the clothes into the drum, and a heat source for the hot air.
, I-L+61;l-H1djhh-H1djhh-Jfifu7e--a control switch that controls the operation of the motor and controls the rotation of the drum, and a changeover switch that changes the operation of the controller according to the amount of cloth. and, in particular,
During small capacity operation, the controller lowers the rotational speed of the motor by changing the changeover switch, thereby improving the fabric rotation of the clothes and allowing efficient drying.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below based on the attached drawings. In FIGS. 1 and 2, 1 is a controller that controls the operation of the dryer, and 2 is a motor that rotationally drives a drum 3 that accommodates clothes and a fan 4 that blows hot air. The motor 2 may be provided separately for the drum 3 and fan 4. 5 is a heater that heats the drying air. 6 to 12 indicate the operation parts of the dryer, 6 is the start switch to start the operation, and 7 is the dryer's 4. '14U is a drying changeover switch, and 8 is a drying changeover display device. Further, 9 is a heater switch for switching the amount of heat generated by the heater 5, and 10 is a heater switching display device. 11 is responsible for the operation of controller 1.11f
This is a selector switch, 12 is a changeover display device.

The operation in the above configuration will be explained.

When the user presses the start switch 6 to start operation,
The motor 2 is driven to rotate the drum 3 and fan 4, and at the same time, the heater 5 is energized. As a result, the clothes J''1 inside the drum 3 roll, and the hot air energizes the inside of the drum 3 to start drying the clothes.

At this time, if the amount of batter in the drum 3 is small, as shown in Figure 3 (A
) As shown in the figure, the clothes will stick to the inner wall of the drum, making it difficult for the clothes to be exposed to heat, resulting in poor efficiency in terms of weight and weight.

Therefore, by using the changeover switch 11, when there are few clothes (
In the embodiment, when the operation of the controller 1 is switched to the rated capacity (or lower), on-off control of the voltage and current applied to the motor 2 is performed, and this decreases the driving force, causing the rotational speed of the drum 3 to decrease to 20. The rotation speed of the clothes decreases by ~30 cm, and as a result, as shown in Figure 2), the clothes spread out without sticking to the inner wall of the drum 3, causing the clothes to become exposed to the hot air. As a result, energy loss is reduced (energy saving rate 20-30%), and efficient drying operation can be performed. Note that the control 1I4I of the motor 2 can also be configured to directly lower the rotation speed instead of on-off control. and again,
The motor 2 may be controlled not only in one stage but also in multiple stages.

Effects of the Invention As described above, according to the uninvented clothes dryer, a changeover switch is provided to change the operation of the controller according to the cloth h↓, and the changeover switch controls the operation of the motor and controls the rotation of the drum. Regardless of the amount of clothes in the drum, the fabric can be wrapped around easily, efficiently blowing hot air, and have a great effect on energy and time savings.Even if the amount of clothes is small, it can be spread out and transferred to another place. Therefore, it is possible to reduce the occurrence of wrinkles, which is a drawback of clothes dryers.
