Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a hand dryer for drying hands by blowing warm air.

[Conventional technology]

As the bathroom vanity, a type that can easily wash not only the face but also the hair has become widespread, and in addition to this, those having various additional functions have come into wide use. For example, a dryer provided with a hot air dryer is accepted as a preferable one for public toilets such as department stores and restaurants in terms of cleanliness. Also, not only the dryer,
There is also a system in which detergent, water spouting, and drying are automatically performed so that hand washing and drying can be performed hygienically without touching the equipment at all.

The dryer using warm air is integrated into the washbasin or
Or, a type in which a dedicated casing is arranged at the back or side of the washbasin and housed in this is generally used. For example,
As the latter having a fixed structure, Japanese Utility Model Application No. 62-1423
There are those described in the specification and drawings of No. 63.

[Problems to be solved by the device]

Hot air from the dryer is blown downward into the washbasin or horizontally to the front. This is a structural ingenuity that has the one purpose of preventing the scattering of warm air and efficiently drying the hands.

On the other hand, the level of the washbasin is such that the user can bend his / her back a little, as can be seen even when washing hands and the like. For this reason,
When the hot air blowing direction of the dryer is horizontal or diagonally below,
The posture is such that you can bend your hips until you dry after washing your hands.
Therefore, especially for a tall person, an uncomfortable posture is forced, resulting in poor usability.

Also, when the warm air blows out to the front side, it is blown to the human body. For this reason, it may be uncomfortable under environmental conditions such as summer or excessive heating.

Therefore, an object of the present invention is to make it possible to dry the hands comfortably without taking an unreasonable posture, and to eliminate the discomfort to the person due to the blowing of warm air so that the person can use it comfortably.

[Means for Solving the Problems]

In order to achieve the above object, the hand dryer of the present invention has a main body integrated with a counter or a wash basin incorporated in the counter, and a hot air supply passage from a warm air generator is connected to the main body. Provided with a jet head for blowing warm air on the main body,
The jet head is characterized in that it has a jet axis which faces the back side of the counter or the washbasin and upward.

〔Example〕

Hereinafter, the features of the present invention will be specifically described with reference to the embodiments shown in the drawings.

FIG. 1 is a side view of a vanity equipped with a hand dryer of the present invention, and FIG. 2 is a perspective view.

In the figure, the faucet is attached to the counter 10 that is fixed using the wall.
The washbasin 10a with 10b is integrated, and the main body 1 of the hand dryer is disposed on the left side of the washbasin 10a with an appropriate distance (for example, about 550 to 600 mm).

FIG. 3 is a view showing a built-in structure of the main body 1 of the hand dryer and a warm air generating mechanism. Although the shape of the main body 1 shown in FIGS. 1 and 2 is slightly different,
The outline is the same.

As shown in the figure, the main body 1 has a rim 1a placed on a counter 10 and is fixed by penetrating the counter 10. Further, a warm air blowing seat 2 and a detection seat 3 for detecting the hand of a person to operate and stop the warm air generating mechanism are formed on the upper surface. The warm air blowing seat 2 is formed as an inclined surface which is oriented so as to face the back side, and the ejection head 2a is attached to the surface thereof. On the other hand, the detection seat 3 has an inclined surface that is raised so as to face the front side, and is equipped with a photoelectric sensor 3a that uses infrared rays and is directed to the front.

On the other hand, below the counter 10, the warm air generator 4 is arranged. The hot air generator 4 includes a hot air fan 5 and a controller 6 in the casing 4a. The warm air fan 5 has an impeller inside the housing 5a.
5b and a heater 5c are provided, and a fan motor 5d for rotating the impeller 5b is attached to the outside of the casing 4a. A duct 5e and a connector duct 5f utilizing a bellows tube are connected to the housing 5a. The connector duct 5f is connected to the lower end of the main body 1 and serves as a system for sending warm air into the internal flow path 2b formed up to the ejection head 2a.
The warm air temperature is detected by a temperature sensor 5g inserted in the housing 5a.

On the other hand, the controller 6 controls energization of the heater 5c and the fan motor 5d of the warm air fan 5, and the photoelectric sensor
The signal from 3a controls energization and de-energization of these devices. In such control, when a person holds his / her hand in front of the photoelectric sensor 3a, the reflected light of infrared rays is reflected by the photoelectric sensor 3a.
Is detected, hot air is blown based on this, and the blowing is stopped when the human hand is no longer detected. For example, the flow is such that the photoelectric sensor 3a detects a human hand, the detection signal is input to the controller 6, power supply to the heater 5c and the fan motor 5d starts, and power supply continues until the human hand is no longer detected. When the hand is removed, the photoelectric sensor 3a detects that the hand is not present, and the detection signal is input to the controller so that the heater 5c and the fan motor 5d are de-energized. Therefore, by incorporating a control circuit for performing such control in the controller 6, a person can dry his or her hand without touching the handle or switch of the device. Instead of such control, the fan motor 5d and the heater 5c are activated by detecting the hand of the person by the photoelectric sensor 3a, and after a certain time has elapsed, these operations are automatically stopped. Of course, it is possible.

Further, since the temperature of the hot air supplied by the hot air sensor 5g is detected, a system for inputting this detection signal to the controller 6 and controlling the energization of the heater 5c so that the temperature is always set is provided. . As a result, hot air of a constant temperature can be constantly supplied, and accidents such as poor drying and burns can be prevented. In addition, if an operation unit for adjusting the temperature is separately provided, comfortable drying can be performed even under the external temperature conditions.

In the above configuration, if you hold your hand in front of the photoelectric sensor 3a, the warm air from the warm air generator 4 is sent to the main body 1,
It is blown out from the ejection head 2a. Since this jet head 2a is on the photoelectric sensor 3a side, that is, on the opposite side to the user and is in an upward posture, warm air flows out in the direction of the arrow in FIG. For this reason, the warm air blows out obliquely upward as compared with the conventional case where the warm air flows horizontally or downward, so that a person can dry his hands in a comfortable posture without bending his waist deeply.

Further, since the warm air from the ejection head 2a flows away in the direction in which the person's back is turned, the warm air does not blow on the human body. Therefore, even in the summer or when the heating is too strong, it can be comfortably used without being steamed with warm air. Further, even if the water droplets on the hand are blown off by the warm air, the water droplets fly away from the person, so that clothes or the like are not wetted.

In addition, although the main body 1 of the hand dryer is incorporated in the counter 10 in the above embodiment, it is of course possible to integrate it into the washbasin 10a.

[Effect of device]

As explained above, in the hand dryer of the present invention,
The warm air is directed toward the person and flows upward. Therefore, the position of the hand can be raised compared to the conventional method of blowing the warm air downward or horizontally, and the user can dry the hand in a comfortable posture without bending the hip deeply. Further, since the warm air does not flow to the side where a person is present, the hot air does not make the person uncomfortable when the temperature is high, and the water drops on the hands do not wet the body.
