Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a clothes dryer.

[Conventional technology]

Conventional clothes dryers detect the drying state of dried items using a humidity sensor or temperature sensor, operate with hot air until drying is completed, and then operate with cold air for a certain period of time. Another type of operation control is to perform hot air operation for a certain period of time and then perform cold air operation for a certain period of time in the same way as above, and even if the hot air operation time in the above fixed time operation control is the shortest,
There was no control for hot air operation time of 5 minutes or less.

Furthermore, when drying naturally, in order to prevent clothes that have become tangled and wrinkled during the dehydration process during washing from getting wrinkled after drying, before hanging them to dry,
They unfolded the tangled clothes, pounded and pulled them to smooth out the wrinkles, and then hung them to dry.

[Problem to be solved by the invention]

'' The process of hanging to dry as described in Section 2 was extremely tedious and took a long time to dry. In order to solve these problems, we devised a method in which the dryer operates with hot air or blows air for a predetermined period of time necessary to remove tangles and wrinkles from clothes before operation, and then hangs the clothes to dry. In other words,
This operating means makes it possible to provide a very efficient drying method that does not require manual loosening, pulling, or tapping to remove wrinkles from tangled clothes before hanging them to dry. However, among the clothes dryers of the above-mentioned prior art, after the start of operation, the hot air operation continues until drying is completed, or even when operating for a fixed time, there is no one that starts the hot air operation or the cold air operation for less than 5 minutes. So,
It was not possible to obtain the effect described in 1. ``more efficiently''. In addition, for users, the shorter the dryer run time, the shorter the time it takes to hang dry, which is convenient, but since the time it takes to loosen wrinkles differs depending on the volume of the clothes, it is more efficient and shorter. To loosen wrinkles, it was necessary to change the operating time of hot or cold air depending on the capacity. Furthermore, conventionally, after the hot air operation, the cold air operation that is performed to cool the clothes and the clothes input slot is for a fixed period of time, and in order to obtain the above effect in a shorter time, it is necessary to change the cooling air time depending on the capacity of the clothes. there were.

An object of the present invention is to solve the above-mentioned problems when hanging clothes to dry, and to provide a clothes dryer that more efficiently loosens tangles and wrinkles formed during washing. Still another object of the present invention is to provide a clothes dryer that completes the process of loosening wrinkles and cooling the clothes and the clothes input port in as short a time as possible, allowing the user to hang them to dry without bothering the user. It's about doing.

=3- [Means for solving the problem] In order to achieve the above purpose, after the start of operation, hot air operation is performed for the minimum necessary time required to remove lumps and wrinkles from clothes before operation, and then operation is stopped. This is achieved by controlling the operation to In addition, in order to achieve other purposes, after starting operation, we first perform a capacity prediction operation to predict the capacity of dry matter, and if the capacity is large, we perform hot air operation and Longer cold air operation
When the capacity is small, this is achieved by controlling the operation by shortening the hot air operation and the cold air operation and stopping the operation.

[Effect]

By controlling the operation described above, tangles formed during washing are loosened by the rotational movement of the drum, wrinkles are smoothed out by hot or cold air, and the operation is stopped. By hanging drying after the above operation, you can avoid the trouble of manually loosening wrinkles and tangles, patting, and stretching the laundry before hanging it to dry, making the drying process more efficient. I can do it.

Furthermore, after the start of operation, the shortest hot air operation time is determined according to the capacity, so wrinkles can be removed in a shorter time and tangles can be loosened, making the above-mentioned line drying work more efficient. .

Furthermore, since the cold air operation time for cooling clothes and the input port is changed depending on the capacity, there is no extra cold air operation time, and the hanging drying work can be performed efficiently.

〔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 outer frame of the dryer, 2 is a door that covers the clothes slot 3 and can be opened and closed freely;
4 is a display panel section, 5 is an operation board, and 6 is a power switch. Reference numeral 7 denotes a control device that drives and controls the electric motor, heater, etc. based on instructions from the microcomputer. Inside the outer frame 1, as shown in FIG. 2, there is a drum 8 which is a drying chamber.
The drum belt 11, the fan belt 12, and the electric motor 13 are used to drive the blower 10 and the drum 8. It is equipped with

Next, the operation of the embodiment of the present invention will be explained based on the operation flowchart of the embodiment shown in FIG. In the clothes dryer having the above configuration, turn on the power switch 6 and start the operation.
When ~ is activated, the electric motor 13 is driven to rotate the drum 8 containing dry clothes, and at the same time the air blower 'fl1.
Rotate O. As a result, the air in the drum 8 is sucked into the blower 10 through the drum intake port 14, passes through the circulation duct 15, and is sent to the heater 9, where it is heated to become warm air and circulated inside the drum 8. . Clothes and the moisture contained in them are heated by this warm air. While performing the above operation, perform capacity prediction operation. Next, the operation of the capacity prediction operation will be explained based on FIG. 5.

The difference ΔT I-I between the temperature measured by the temperature detection device 16 provided in a part of the drum intake port 14 and the outside air temperature measured by the temperature detection device 17 is determined by the following three drying periods as well as the drying process. Changes in pattern. After the start of operation, clothing and moisture contained in clothing are heated and ΔT
A preheating period in which H continues to rise, a constant rate drying period in which the moisture contained in the clothing constantly evaporates and ΔTH reaches a constant temperature ΔTHHx, and a decreasing rate drying period in which moisture evaporates and ΔTH increases by 2. It is. During the preheating period, a certain period of time T. (In this example, it is set to 3 minutes) ΔT I (as shown in FIG. 5, the larger the capacity (G1: small amount).

G2: Medium amount, G3: Large amount) ΔTH,, ΔTH,.

It becomes small like ΔTH3. In other words, the drum intake port 14
The capacity of the clothes in the drum 8 can be predicted by detecting the difference ΔTH between the temperature provided in a part of the drum 8 and the outside temperature at a certain fixed time after the start of operation. On the other hand, Figure 4 shows the hot air operation time required to remove tangles and wrinkles during washing, and the cold air operation time required for the user to no longer feel the clothes and clothing input port 3 being hot after hot air operation, and these are shown for each capacity. This is what is shown. This information is stored in the control device 7, and the hot air operation time T1 and the cold air operation time T2 are determined based on the capacity predicted by the capacity prediction operation, and the control device determines the hot air operation time T1. After operating for the cold air operation time T2, the command to stop operation +I- is issued.

According to this example, the tangles and wrinkles caused during washing can be loosened and the wrinkles removed by the warm air operation of the dryer, and the wrinkles can be further removed. Since the operation ends, there is no wasted operation, and the process can be completed more efficiently and in a shorter time, allowing for long-lasting hanging drying. Furthermore, by performing the second operation control, it is possible to eliminate the trouble of manually loosening, stretching, and pulling clothes when hanging them to dry. In addition, regardless of the size of the capacity, the cold air operation can efficiently cool the clothes and the clothes input port within a predetermined time required to cool them, and the clothes can be taken out more safely. The cold air operation described in Section 2 is a process designed to make it safer to take out clothes, and even if this process is not included, it will have no effect on the effects of loosening tangles and removing wrinkles from clothes. It is not a hindrance.

In addition, the capacity prediction operation method does not require the method of predicting based on the difference between the temperature at the drum outlet and the temperature of the outside air as in the embodiment. Regardless of the location of temperature measurement or the means for predicting temperature, as long as the capacity of clothing can be predicted, the operation and effects of the present invention will not be affected in any way.

〔Effect of the invention〕

According to the present invention, the tangles and wrinkles formed during washing can be loosened and wrinkled by the hot air operation of the dryer without the trouble of manually loosening or pulling them, and the wrinkles can be further removed regardless of the size of the capacity. You can hang dry with a good finish more efficiently and in a shorter time without unnecessary operation.

In addition, regardless of the size of the clothes, the cold air operation can efficiently cool the clothes and the clothes input port in the shortest time required to cool them, and the clothes can be taken out more safely.
