Abstract

PURPOSE:To eliminate the need of a long hour for drying clothes outside a drier and prevent the occurrence of a damp-dry state under an adverse weather condition by detecting the surrounding humidity and temperature of a drier for the concerned clothes before the operation of the drier respectively with humidity and temperature detectors, and informing a user accordingly when an atmospheric condition is not suitable for the natural drying of the clothes. CONSTITUTION:A control device 7 for controlling a drying operation is provided with a humidity detector 8 for detecting humidity surrounding a drier, and a temperature detector 9 for detecting temperature surrounding the drier. A drum having a drying chamber is pivotally supported in the body 1 of the drier in such a way as to be freely rotatable. In addition, the inside of the body 1 is provided with a heater and an air blower for supplying hot air to the drum, and a transmission device and an electric motor for driving the aforesaid air blower and motor. According to the aforesaid construction, it is possible to recognize whether the surrounding condition of the drier is suitable for the natural drying of clothes through the humidity and temperature detectors provided in the drier. As a result, a long hour is not needed for drying the clothes due to natural drying at a place of high humidity on a rainy day or the like, and the occurrence of a damp-dry state condition can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a clothes dryer, and particularly to a clothes dryer that utilizes the relative humidity of outside air during drying.

[Conventional technology]

Although there is no known example of controlling the drying operation by detecting the relative humidity of the outside air during drying, there is a method known in Japanese Patent Application No. 1-92873 that performs laundry according to the weather, and a method that automatically forecasts the weather. There is Utility Model Publication No. 58-13727 as a device.

[Problem to be solved by the invention]

When drying clothes naturally, the humidity of the outside air has a large effect on drying. In other words, if the humidity is high, it will take a long time to dry the clothes, making it impossible to dry them thoroughly. In such cases, you can dry your clothes sufficiently by using a clothes dryer.

However, the only way to determine whether natural drying was suitable during the dry season was to look at the weather forecast and the condition of the sky.

Therefore, an object of the present invention is to provide a clothes dryer that has a means for measuring the relative humidity of the outside air at the time when clothes are to be dried, informing the user of the weather conditions, and allowing the user to use this as a guide when drying clothes. It is to provide.

[Means to solve the problem]

The above problem is solved by installing a humidity detection device in the dryer to measure the relative humidity, and importing the data measured by the humidity detection device into the control device. This is achieved by notifying the user through display means such as a - code.

[Effect]

The humidity detection device, control device, and display device allow you to know the relative humidity of the outside air, so you can avoid drying clothes outside the dryer when the weather is not good and the clothes may take a long time to dry or become half-dry. This can be prevented.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 5.

FIG. 1 is an external view of the dryer of the present invention.

1 is the main body of the dryer, 2 is a door that covers the clothes slot 3 and can be opened and closed freely, and 4 is a display panel that houses an operation board 5 having a display function and a power switch 6.

It is a storage section with a frame structure for holding. 7 is a control device for controlling the drying operation, 8 is a humidity detection device for detecting the humidity around the dryer, and 9 is a temperature detection device for detecting the temperature around the dryer. Although not shown, inside the main body 1, a tram with a drying chamber is rotatably supported, and a heater and a blower device for sending hot air into the tram are provided, and the blower device and the drum are driven. It is equipped with a transmission device and an electric motor for.

2 and 3 are control circuit block diagrams of the present invention. The area inside the broken line 10 indicates the control device section in FIG.
It is composed of a microcomputer 12 and the like.

Some devices use this to drive a motor, heater, etc. to advance the drying operation.

Power is supplied by inserting the plug 11 into the power outlet, and the power switch 6 with an auto-off switch function cuts both loads, and 14 is the door 2 in Figure 1.
This is a door switch that temporarily stops operation when the door is opened. 5 displays the display on the display panel shown in FIG. 4 according to the output signal from the control device 7, and controls the heater switching 15,
This is an operation board for setting the drying switch 16. Reference numerals 8 and 9 are the humidity detection device and the temperature detection device respectively explained in FIG.

Next, the operation of the embodiment of the present invention will be explained.

The ease with which clothes can be naturally dried depends not only on the ambient humidity, but also on the ambient temperature. In other words, even if the humidity is the same, if the temperature is low, it will be difficult to dry, and if the temperature is high, it will be easier to dry.

Each curve in FIG. 5 shows the relationship between temperature and humidity at the same degree of freshness of air, and in the present invention, it is set to equation (1).

4, 8 seek. If this Y is larger than the ambient humidity or the ambient humidity obtained by the humidity detecting device, then (fifth
(shaded area in the figure), the light emitting diode 13 provided on the operation board 5 blinks.

As described above, according to this embodiment, when the ambient humidity is not suitable for drying clothes naturally, the light emitting diode notifies the user of this and allows the user to use the dryer, allowing the clothes to dry naturally for a long time. Clothes can be dried more efficiently without wasting time.

〔Effect of the invention〕

According to the present invention, since it is configured as described above, it produces the effects described below.

The humidity detection device and temperature detection device installed in the dryer can tell you whether the conditions around the dryer are suitable for natural drying or not, so you can dry it naturally in a humid place such as on a rainy day. It can be dried efficiently without taking a long time or drying out.
