Description

Detailed Description of the Invention 【Technical field】

The present invention controls the warm air temperature of a warm air drying device that cleans a local area with warm hot water discharged from a nozzle of a warm water cleaning device after use, for example, and then blows warm hot air to a wet location to dry it. On how to do.

BACKGROUND ART The warm air temperature of a warm air drying device provided in a warm water washing device designed to wash a local area with warm water after use is high immediately after the start of drying, but the temperature gradually changes depending on the dryness of water. It is necessary to lower it. Further, there are individual differences in the appropriate use temperature of the hot air for drying. For this reason, in the conventional warm air drying device, the user individually sets the warm air temperature immediately after the start of drying and the finally calm warm air temperature by using two kinds of temperature setting buttons. Therefore, when the user sets the warm air temperature according to the individual difference, it is necessary to select two set temperatures and set them with the temperature setting button, which is a disadvantage in that the temperature operation is troublesome.

[Object of the invention]

The present invention has been made in view of the above technical background, and an object thereof is to simplify the setting of the warm air temperature of the warm air drying device.

DISCLOSURE OF THE INVENTION

The hot-air temperature control method of the hot-air drying device of the present invention, when the hot-air temperature is selected and the temperature setting buttons a, b, ..., H are set, high-temperature hot air of a constant temperature T ₁ is jetted out first, The set temperature
The feature is that the temperature of the warm air is gradually decreased toward T ₂ . However, the temperature of the warm air immediately after the start of drying is fixed, and as the set temperature of the warm air blown out from the warm air drying device, it is sufficient to set only the temperature of the warm air that will eventually settle down. It is not necessary to set the temperature of the hot air immediately after, and the temperature of the hot air can be easily set. That is, there are individual differences in the operating temperature of the hot air for drying the topical area, but there is almost no individual difference in the operating temperature because the hot air does not directly contact the skin immediately after the start of drying when a large amount of water remains locally. Even if the temperature of the warm air immediately after the start of drying is kept constant, the drying can be performed comfortably and the troublesomeness of temperature setting can be reduced. Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. First
In the figure, the relationship between the preferable warm air temperature of the warm air drying device (not shown) and the elapsed time is shown in a graph. That is, in the section a, since many water droplets are locally attached and the skin surface is wet, heat is not directly transmitted to the skin even if hot air is blown, and there is no individual difference in heat sensation. Also, since much water is attached, it is necessary to dry at high temperature T ₁ . In section (b), the skin surface begins to dry, so it is necessary to gradually lower the warm air temperature. In interval C there are individual differences in operating temperature for is progressing drying of the skin surface, set temperature T ₂ that is set individually
Need to be dried. FIG. 2 shows a temperature setting button having eight push buttons a, b, ..., H capable of setting the temperature in eight steps. The temperature setting buttons a, b, ..., H are provided on the upper surface of the main body of the apparatus in which a hot water tank of a normal hot water washing apparatus (not shown) and an electronic circuit for control are built. The eight temperature setting buttons a, b, ..., H correspond to the following set temperatures, for example. a …… T ₂ = 49 ℃ b …… T ₂ = 52 ℃ c …… T ₂ = 55 ℃ d …… T ₂ = 58 ℃ e …… T ₂ = 61 ℃ f …… T ₂ = 64 ℃ g… … T ₂ = 67 ° C h …… T ₂ = 70 ° C Also, the warm air temperature T _{1 in} section a immediately after the start of drying is a constant temperature.
It is fixed at 70 ℃. Then, when the user selects the set temperature T ₂ according to the individual difference and presses the temperature setting buttons a, b, ..., h, hot air at a constant high temperature T ₁ (70 ° C) is initially discharged. Then, the temperature of the warm air gradually decreases, and finally reaches the set temperature T ₂ , and thereafter, the set temperature T ₂ is maintained. Here, when each set temperature T ₂ is set, a pattern such as the number of stages of temperature change and the temperature change time to shift from the initial temperature T ₁ to the set temperature T ₂ is built in the hot water cleaning device in advance. It is stored in the control microcomputer. FIG. 3 shows how the temperature setting button d is pressed to set the temperature to T ₂ = 58 ° C. Therefore, if the user selects and sets the temperature around the time when the local area where there is individual difference begins to dry, the warm air temperature in the stage from the beginning to the drying is automatically controlled according to the program, and the warm air drying device Is easy to use. In the illustrated example, the warm air temperature is set to 8 stages, but it is of course possible to set the number of stages other than this.

【The invention's effect】

According to the present invention, when the temperature of the hot air is selected and the temperature setting button is set as described above, first, hot air of a constant temperature higher than the set temperature is ejected, and the temperature of the hot air is gradually increased toward the set temperature. Since the warm air temperature is kept at the set temperature after being lowered to the set temperature, the final set temperature of the hot air blown out from the warm air drying device is the final temperature. Since it is only necessary to set the temperature of the warm air that is calm and the initial temperature control is performed automatically, it is possible to easily set the temperature of the hot air and reduce the troublesomeness of the temperature setting. There are advantages. Moreover, since a large amount of water remains locally and the hot air does not directly hit the skin immediately after the start of drying, it is possible to dry comfortably even if the temperature of the hot air immediately after the start of drying is kept higher than the set temperature and constant. Is something that can be done.
