[0004]

SUMMARY OF THE INVENTION It is an object of the present inventors to provide the above-mentioned improved microwave oven or its drying method.

[0005]

The essence of the present invention is to provide at least one of an infrared sensor of 100 ° C. or higher, a humidity sensor, and a weight sensor, which are sensors for detecting temperature, steam, and weight of a microwave oven at 100 ° C. or higher. By installing the above,
The above problems have been solved by providing a method for drying clothes that controls heating and has good heating efficiency.

The outline of the subject matter of the present invention is as follows.

(1) A microwave oven for drying clothes is characterized by having a temperature sensor for detecting the temperature of the inside clothes of 105 ° C. or more and a function of turning off the power at a predetermined temperature of 105 ° C. or more. A microwave oven for drying clothes.

(3) In a microwave oven for drying clothes, a microwave oven characterized by sensing exhaust humidity or the weight of the clothes or the whole.

(4) The microwave oven for drying clothes according to claim 3, wherein the sensor for detecting humidity or weight is a humidity sensor or a weight sensor.

(5) The microwave oven for drying clothes according to claim 4, wherein the humidity sensor or the weight sensor automatically turns off the power when it senses a predetermined value.

(6) For drying clothes, which is characterized in that a plurality of temperature sensors monitor the clothes installation section and the power is automatically turned off when one of them reaches a temperature higher than the boiling point of water. microwave.

(7) The microwave oven for drying clothes has a temperature sensor, a weight sensor or a humidity sensor, and when the temperature sensor is 80 ° C. or higher, the value of the humidity sensor or the weight sensor is substantially at least a predetermined number of seconds. A microwave oven for drying clothes, which is characterized in that the power is automatically turned off when the same value is shown above.

A microwave oven for drying clothes is provided with a sensor for detecting temperature, steam and weight above the boiling point of water. The microwave oven detects temperature, steam and weight above the boiling point of water. These sensors are infrared sensors, humidity sensors, and sensors that can measure temperatures at least above the boiling point of water.
A microwave oven for drying clothes, which is characterized by being a weight sensor.The microwave oven for drying clothes is characterized in that the inside of the main body is made large so that one or more clothes can be hung and hung. A microwave oven for drying clothes, characterized in that it is possible to dry clothes and a switch for a course for drying clothes is turned on.

If a microwave oven for cooking is used,
When drying clothes, it is difficult to control heating, and there is a great possibility that the above-mentioned phenomena such as charring, shrinking, melting, and ignition will occur. Therefore, by paying attention to steam, temperature, and weight, which are changes in the clothes that occur until the clothes are heated and dried, at least one of each sensor is attached, and the change is detected and the clothes are dried. Is to do.

It should be noted that the weight sensor not only measures the change in the weight of the washed clothes, but also the skillful method of measuring the weight of the clothes by measuring the entire microwave oven. This is because it is not only difficult to install a weight sensor that can be measured only with clothes inside the range, but there is a risk of heat generation. Since it takes a whole system, it can be easily done just by using it at the bottom of the range. As an extreme example, a microwave oven may be placed on a commercial scale.

[0017]

The present invention will be described in more detail with reference to the following examples. However, the effectiveness of the present invention is
It should not be construed as limited.

By modifying a commercial 1500W microwave oven,

In FIG. 1, 4. Attach a humidity sensor to the exhaust,

FIG. 2. The infrared temperature measuring instrument was modified and the sensor section was changed to 11. It was installed inside for hanging clothes.
9. The weight sensor was installed at the bottom so that the weight of the clothing can be detected by measuring the entire microwave oven. The temperature sensor is 6. In the temperature control setting section, it can be set above the boiling point of water. Humidity and weight are 7. Humidity control setting section and 8. In the weight control setting section, if the rate of change is set and the humidity is set to 1, it becomes 1
When the humidity changes by only 1% per minute, and the weight is set to 5, the power can be set to be turned off when only 5 g changes per minute.

One piece of polypropylene clothing (250
When g) was washed and dehydrated, the temperature of the upper part reached 105 ° C, and when the power was turned off, the upper part was completely dried and the lower part was almost dry. Regarding humidity and weight, when the rate of change below a certain level per hour (whether it is completely dry or not), the power is turned off. If it is a little dry, then
May be dried in room. 172 for polypropylene
Since it is good if it is less than or equal to the degree, it is necessary to set the value less than that. By mounting the temperature control sensor in this manner, not only polypropylene but also polyester and other various materials can be used.

[0020]

[Preferred range] The amount of water contained in the clothes to be dried does not matter. For example, dehydration by a dehydrator or a dehydration method in which dripping drops are dripping by hand only affects the drying time and does not affect the machine as in a conventional dryer.

Since the drying method uses dielectric heating by high frequency which is a heating method peculiar to a microwave oven, it is preferable that the clothes to be dried do not contain metal. Further, in consideration of the influence on clothing, it is particularly preferable to use a fiber having a low dielectric constant that is less likely to be affected by high frequencies, for example, a fiber such as polypropylene or polyester.

It is preferable that the number of temperature sensors attached is large. It is preferable to attach a plurality of them to the left, right, front, rear, upper part, and lower part, but there is a limit because the manufacturing cost must be considered.

It is preferable that the hanging portion for hanging the clothes is made of a material that is not significantly affected by high frequency heating.

[0024]

[Modifiable Range] The present invention includes the following configurations as the contents of the invention.

It is possible to manufacture a microwave oven for drying clothes by attaching a humidity / temperature / weight sensor to the cooking microwave oven. However, the main body for drying clothes is made larger and a dedicated drying apparatus is used. Treat as.

Although various sensors are attached for drying clothes, the microwave oven for cooking can also be used for heating and cooking food.

Since it is possible that the power source is turned off by heating the parts other than the clothing, a reheating function may be provided. 9
At a temperature of about 5 degrees, there may be a function of notifying by voice that the completion of drying is approaching. Alternatively, the high frequency wave may be emitted in the direction of lower temperature. For example, since the water is likely to drop in the lower part, the lower part may be concentrated.
Considering the case where dripping drops dripping on the bottom of the refrigerator, a saucer, which is a material that is not easily affected by high-frequency heating such as water, may be placed.

Depending on how to put the clothes to be dried, they may be hung on the hanging part, hung, or folded and put on the bottom of the refrigerator.

[0029]

EFFECTS OF THE INVENTION In drying clothes by the heating method of a microwave oven, (1) the time required for drying is short (2) the energy required for drying is small (3) the drying time is determined by the sensor, so it is not necessary to set it. (4) Useless energy is not applied because it automatically stops at the end of drying
