Description

[Detailed Description of the Invention] [Industrial field of application] The present invention provides a guideline for the drying time to a user in a device that blows warm air onto the hand by holding a wet hand after cleaning to a predetermined position to dry the hand. To provide, the present invention relates to a warm air drying device including a display device that displays elapsed time at the start of use of the device.

[Conventional technology]

Conventionally, a warm air drying device has a structure in which when a hand is held over a predetermined position (in the vicinity of the hot air outlet), the electric motor and the heater are energized by the output signal of a sensor that detects the presence or absence of the hand to perform a hot air discharge operation. Is used.

[Problems to be solved by the device]

However, in the above-mentioned conventional device, the user has a drawback that the degree of dryness of the hand depends only on the sense of touch, and there is no standard for drying.

Also, if the fan makes a lot of noise when the hot air dryer is operating, the user often feels this noise and feels the time it is dry longer than it actually is, and before the hands are completely dried. There is also a problem that the use of the warm air drying device is stopped.

The present invention has been made in view of the above problems, and provides a warm air drying device configured to present a user with a general drying time and a remaining time until drying, and to measure a standard of drying. The purpose is.

[Means for Solving the Problems]

In order to achieve the above object, the warm air drying device according to the present invention holds a hand over a predetermined position, a sensor senses the hand and energizes an electric motor and a heater to discharge hot air to the predetermined position. In the warm air drying device, an elapsed time display unit formed by arranging a plurality of light emitting elements is provided in the apparent part of the machine casing of the warm air drying device, and is installed in the machine casing at the same time as the detection signal of the sensor. The central control mechanism counter is configured to be able to display an index of dryness by lighting or extinguishing or blinking the light emitting elements sequentially in correspondence with time display through a lighting circuit. .

[Action]

That is, in the above configuration, when the sensor detects the presence of the hand, the electric motor and the heater are energized to start the hot air discharge operation, but at the same time as this operation starts, the elapsed time display section provided in the apparent section of the machine casing is started. Lighting or blinking of the arranged light emitting elements informs the user of the average degree of dryness along with the elapsed time.
The user can use this notice as a measure of dryness.

〔Example〕

An embodiment of the warm air drying device according to the present invention will be described below with reference to the drawings.

In the drawing, reference numeral 1 denotes an electric motor installed in a machine casing 2 of the present apparatus, which is formed by attaching fans 4 and 4 to both ends of a rotary shaft 3 protruding from both ends of the electric motor 1. The fans 4 and 4 are fan ducts 5 fixed to the machine casing 2, respectively.
In the air duct of the fan ducts 5 and 5, the fan ducts 5 and 5 are provided so as to be rotatable relative to the base of the fan ducts 5, and the air outlets 6 and 6 of the fan ducts 5 and 5 are opened to the warm air blowout portion 7 of the machine casing 2. It has a structure in which the heaters 8 and 8 are respectively installed inside. Thus, the air blown by the fans 4, 4 is heated by the heaters 8, 8 in the ventilation passages of the fan ducts 5, 5 and is discharged as warm air from the air outlets 6, 6.

Reference numeral 9 denotes an optical sensor having a pair of a light emitting element and a light receiving element for detecting a hand held below the warm air blowing portion 7, and a central control mechanism 10 installed in the machine casing 2 The presence / absence signal of the hand at the partial position is turned on and off, and the electric motor 1 and the heaters 8 and 8 are energized or deenergized via the central control mechanism 10.

Reference numeral 11 denotes an elapsed time display section provided on the front cover section 2a of the machine casing 2, and the plurality of LEDs 1 corresponding to the time display 12 are provided.
The light emitting elements such as 3 are arranged and the LEDs 13, 1 are arranged.
.. are turned on, turned off, or blinked by the counter 14 of the central control mechanism 10 through the lighting circuit 15 in order corresponding to the time display 12.

FIG. 4 shows that the elapsed time display section 11 has 15 LEDs 13,
When the sensor 9 detects a hand, the first LED 13 is delayed by a predetermined time T1.
Blinks at a constant cycle (0.5 second cycle in this embodiment), lights after a predetermined time (2 seconds in this embodiment), and causes the second LED 13 to flash at the same cycle. Then, the LEDs of the second or lower LED are sequentially arranged according to the elapsed time.
Similarly, 13, 13, ... Are blinked and turned on to display the elapsed time.

The time display is full scale, for example, 3 in this embodiment.
When 0 seconds has passed, all the LEDs 13, 13 ... Are extinguished, and when the hand is further detected, the first LED 13
Repeat the above blinking and lighting. In addition, when the detection of the hand by the sensor 9 is stopped, the entire time of the L
The EDs 13, 13 ... Are turned off.

The method of displaying the elapsed time is not limited to the operation example of the LEDs 13, 13, ...
3 and 13 are turned on, and each LED after the passage of time
All LEDs 1, 13 ... Are blinked at a constant cycle and all LEDs 1 are detected by the hand detected by the sensor 9.
It is also possible to turn on 3, 3, ... And turn them off by a subtraction type or a progress type according to the passage of time.
Furthermore, when the time display is full scale, all LEDs are
It is also possible to have a configuration in which 13, 13, ...

It should be noted that it is also a preferable method to display the average dryness in parallel on the time display 12 or change the color development of the LEDs 13, 13 ... In accordance with the dryness.

In the warm air drying device configured as described above, the sensor 9 detects the presence or absence of the hand by holding the hand over a predetermined position (below the warm air blowing portion 7), and the electric motor 1 and the heaters 8, 8 are connected.
The counter 14 of the central control mechanism 10 simultaneously counts the elapsed time and the elapsed time is turned on by the lighting circuit 15
The LEDs 13, 13, ... Of the elapsed time display portion 11 are sequentially turned on, turned off, or blinked via. Therefore, the user can perform the drying operation by checking the average degree of dryness displayed on the elapsed time display unit 11 while holding the warm air discharged from the air outlets 6 and 6 with his / her hand. For this reason, the user is free from the anxiety of relying only on the sense of dryness, and can ensure the dryness.

The structure of the elapsed time display unit 11 is an example of the structure, and the arrangement of the LEDs 13, 13 ... Or the LED 1
Needless to say, the display means in place of 3, 13, ... Is not limited to the above embodiment.

[Effect of device]

Since the hot-air drying device according to the present invention is configured as described above, since the elapsed time display unit for displaying the elapsed operation time is provided in the apparent part of the device casing, the user can set the dryness The effect of giving the user a feeling of satisfaction with the dryness is obtained, and the practical effects of the embodiments of the present invention are great.
