Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air jet drying device for wiping an article after washing with an air stream to dry the article.

[0002]

2. Description of the Related Art At the work site where food is manufactured and handled, it is important to keep hands and feet and equipment used clean. As is well known, performing washing such as washing with water is a simple and effective means for cleaning. However, for example, in order to make the limbs hygienic and clean, it is necessary to hygienically perform not only the washing treatment but also the drying treatment after washing. It is widely practiced to wipe your hands wet with a towel or a handkerchief, but if the towel or a handkerchief is dirty, wiping will result in an unclean state.

Therefore, there has been developed a drying device as disclosed in, for example, Japanese Patent Laid-Open No. 23918/1990, which directly dries washed and wet hands without using a towel or the like. As shown in FIG. 9, the drying device disclosed in the above publication has an electric motor 101 and blades 102 rotated by the electric motor 101.
And a heating means by the electric heater 103. The air blower forms an air flow blown to the hand dryer 104 by the rotation of the sirocco type blades 102, and the electric heater 103 heats the air flow formed by the blower to heat the air blown to the hand dryer 104. Let the wind.

In the hand dryer having the above structure, the hand can be hygienically dried by holding the wet hand over the hand drying unit 104 in which warm air is blown. That is, the water content of the hand hit by the warm air is evaporated by the heat and is blown away by the air to be removed from the hand. The drying device of the above publication is devised so that the blowing temperature of the warm air is constant regardless of the temperature of the sucked air in order to shorten the drying time and obtain comfort. Although this drying device is limited to the target to be dried, a device for drying an article that has been wet with water generally has a configuration similar to this drying device.

[0005]

In the conventional drying apparatus as described above, for example, in the case where the hand is the object to be dried, the temperature of the warm air is set relatively low because the warm air is directly applied to the hand. In addition, since the wind speed is relatively low, it takes a long time for the drying process. Such a problem is inherent in a drying device that attempts to remove water by the action of both heat and wind, even if there is a difference in the object to be dried.

The present invention has been made in order to solve the above-mentioned problems, and a problem thereof is to obtain a compact air jet drying apparatus capable of performing a drying process in a very short time, and the function of the apparatus. To improve cleanliness and waterproofness, and to obtain an easy-to-use air jet drying device.

EXAMPLES Example 1. First, the basic structure of an air jet drying apparatus as an embodiment of the present invention will be described with reference to FIG. In FIG. 1, the outer shell 1 of the main body is formed into a cylindrical body with both ends closed. A box structure member 2 that also serves as an attachment structure for attaching to a mounting partner such as a wall surface is fixed to the peripheral surface of the main body outer shell 1 in the vertical direction. The box structure member 2 has an opening at the lower end, and the inner space thereof is an intake port 3 formed in the outer peripheral portion of the main body shell 1 at the upper part
Have been contacted. The suction port 3 is opened near the upper end of the main body shell 1, and a circuit case 4 incorporating a control circuit and the like is attached to the upper part of the main body shell 1 facing the suction port 3. Immediately below the circuit case 4, a silencer 6 having a suction passage 5 in the center is attached with the suction passage 5 in the vertical direction. Immediately below the silencer 6, a high-pressure air generator 7 is provided with a suction passage 5
It is assembled with its suction side facing the end and its discharge side downward. The discharge side of the high-pressure air generator 7 is surrounded by the chamber structure 8 and is located in the lower portion of the main body outer shell 1.
At the lower part of the chamber structure 8, a blowout nozzle 9 having an integral structure or a separate structure is provided. The air outlet 10 of the air outlet nozzle 9 is open downward at the lower end of the main body shell 1.

When the high-pressure air generator 7 is operated in the above structure, external air is sucked from the opening at the lower end of the box structure member 2, passes through the box structure member 2, and the suction port at the upper part of the main body outer shell 1. 3 is sucked into the outer shell 1 of the main body, is sucked into the suction passage 5 of the muffler 6 while being in contact with the circuit case 4, and is sucked into the high-pressure air generator 7. The high-pressure air generator 7 raises the pressure of the sucked air, converts it into high-pressure air, and sends it into the chamber structure 8. The high-pressure air sent to the chamber structure 8 is vigorously blown out of the outer shell 1 of the main body from the blow-out port 10 as high-speed air having high kinetic energy by the blow-out nozzle 9 connected to this. If the wet object to be dried is exposed to the high-speed air, the water that wets the surface of the object to be dried is immediately blown off and is wiped from the surface of the object to be dried.

Embodiment 2. This embodiment is a specific application example in which the air jet drying device having the basic structure shown in the first embodiment is applied as a drying device for drying a hand. However, the basic configuration is the same as that of the first embodiment. Therefore, the same parts as those of the first embodiment are designated by the same reference numerals in the drawings, and the description thereof will be omitted.

FIG. 2 and FIG. 3 show an air jet drying apparatus according to the second embodiment of the present invention. The box structure member 2 is hooked to a mounting member such as a wall surface, screwed, or a power line is passed through. A mounting structure 11 is provided for the purpose. An air filter 12 that obliquely traverses the inside of the box structure member 2 is detachably mounted in the box structure member 2 so as to face the opening at the lower end and to have a large filtration area with a small projected plane area. The diameter of the main body outer shell 1 is determined based on the outer diameter of the high-pressure air generating portion 7 since there are almost no components to be installed in parallel in the main body outer shell 1, and actually 25 cm to
It is about 30 cm. Body outer shell 1 is a circular top lid 1
3 and a cylindrical body 14 and a spherical lower lid 15,
The body portion 14, the upper lid 13 and the lower lid 15 are all assembled by fitting. These upper and lower fitting portions 16 are formed so that the upper one is externally fitted to the lower one. That is, the diameter of the upper lid 13 is larger than that of the body portion 14, and the upper lid 13 covers the upper end of the body portion 14 from the outside. The diameter of the body portion 14 is larger than that of the lower lid 15, and the lower end of the body portion 14 covers the upper end of the lower lid 15 from the outside. As a result, the waterproof property of the fitting portion 16 of the main body outer shell 1 can be improved with a simple configuration, and troubles due to water intrusion can be avoided.

The circuit case 4 incorporated in the uppermost part of the outer shell 1 of the main body is of a hermetically sealed type, and the radiating fins are exposed on the outer peripheral side, and the outer peripheral surface is attached to the suction port 3 of the outer shell 1 of the main body. There is. Therefore, the air flowing in from the suction port 3 comes into contact with the heat radiation fins of the circuit case 4 and flows toward the silencer 6, so that the circuit case 4 is effectively cooled.

The silencer 6 is attached to a middle stage in the outer shell 1 of the main body, the outer shell 17 and the inlet side of the suction passage 5 are made of a rigid body, and the inside is filled with a sound deadening material 18 such as urethane resin. There is. The inlet of the suction passage 5 widens toward the end and opens upward.
Is formed by and extends linearly downward to open. A space is provided between the outer circumference of the muffler 6 and the inner circumference of the body portion 14, and a damping material or a sound absorbing material can be interposed in this portion as necessary.

The high-pressure air generator 7 includes a DC brushless motor 19 (a normal commutator motor may be used, but a DC brushless motor is better for compactness and higher performance), and a DC brushless motor 19 It consists of a turbo fan 20 that rotates by
Is attached so that the discharge side faces downward, facing the end of the suction passage 5. A sound deadening material 18 made of urethane resin is attached to the outer periphery of the DC brushless motor 19.

An outlet nozzle 9 is integrally formed in a tubular shape in the lower portion of the chamber structure 8. Blowing nozzle 9
The air outlet 10 is open downward in the vicinity of the spherical projecting end of the lower lid 15 (on the side opposite to the side on which the box structure member 2 is located). A sensor 21 for detecting the presence or absence of a hand to be dried is attached near the outlet 10 on the spherical protruding end of the lower lid 15 which is closer to the rear portion than the outlet 10.
The hand detection output of the sensor 21 is processed by the control circuit in the circuit case 4, and the high pressure air generator 7 is processed through the drive circuit.
To operate.

In the air jet drying apparatus having the above structure, when the wet hand is put out below the lower lid 15 of the outer shell 1 of the main body, the sensor 21 detects the presence of the hand and the high pressure air generating section 7 operates to blow out the air. High-speed air is blown from the nozzle 9 toward the hand. The air passing through the box structure member 2 becomes clean after dust is filtered by the air filter 12, and is sucked into the body outer shell 1. Therefore, the adhesion of dust to the components inside the main body outer shell 1 is small, and the high-speed air blown toward the hand is also clean. The operation of the high-pressure air generator 7 that handles a large air volume normally causes a relatively large operating noise, but the noise generated on the suction side is silenced by the silencer 6, and the noise from the DC brushless motor 19 is Since the sound deadening material 18 attached to the outer periphery of the material silences the sound, the cleanliness is quite high.

When the hand is extended, the lower lid 15 is formed in a spherical shape which bulges downward, and when the both hands are naturally extended, the lower lid 15 fits within the palm of the furniture, so that there is no sense of discomfort and the air outlet is present. It is easy to use because there is a part where 10 is visible. By moving the extended hand appropriately and applying high-speed air to the entire hand, the moisture adhering to the hand is blown off and wiped from the hand. The time during this period is as short as 10 seconds. The user has a feeling that the water in the hand is removed, and when the user who notices that the hand is dried returns his hand, the sensor 21 detects the absence of the hand and the driving is stopped.

Example 3. This embodiment relates to the blow-out nozzle 9 of the air jet drying device for drying the hand shown in the second embodiment. Therefore, the basic configuration other than the blowing nozzle 9 is the same as that of the second embodiment, and the same parts as those of the second embodiment are denoted by the same reference numerals in the drawings and their description is omitted.

FIG. 4 and FIG. 5 show the air jet drying apparatus of the third embodiment. The air jet drying apparatus of this embodiment is characterized by the shape of the blowing nozzle 9.
That is, the air outlet 10 of the air outlet nozzle 9 is opened as a linear slit in a direction perpendicular to the direction in which the hand is extended.
The length of the air outlet 10 is set so as to cover the entire hands when the two hands are naturally aligned and extended. As a result, the high-speed air blown out from the air outlet 10 has a curtain shape, and has a function of blowing off the moisture in a wide range, so that the hand can be dried more quickly.
Since the other functions are the same as those of the second embodiment, the description thereof will be omitted.

Example 4. In this embodiment, the nozzles of the air jet drying device for drying the hand shown in the third embodiment are arranged in parallel. Therefore, except for the configuration related to the nozzle, it is the same as that of the third embodiment, and the same parts as those of the third embodiment are denoted by the same reference numerals in the drawings and their description is omitted.

FIG. 6 and FIG. 7 show the air jet drying apparatus of the fourth embodiment. The air jet drying apparatus of this embodiment is characterized in that the nozzles are arranged side by side in front of and behind the sensor 21. That is, the blowing nozzle 9 of Example 3 was used as the main nozzle, and 50 mm to 70 mm
This is a configuration in which a sub nozzle 23 having another linear air outlet 22 is disposed in the back at a distance. The outlet 22 of the sub nozzle 23 is configured to be shorter on the left and right than the outlet 10 of the main nozzle. The distance between the outlets 10 and 22 arranged in parallel is set in consideration of factors such as the flow velocity of high-speed air, but if they are too close, the air blown out from both outlets 10 and 22 will attract each other, and the reaching distance will become shorter and If it passes, the effect of paralleling is lost. That is, the sub-nozzle 23 forms an air flow for eliminating the influence of the static air around the blow-out nozzle 9 which is the main nozzle.

The high-speed air from the single blow-out nozzle 9 as shown in the third embodiment is affected by the stationary air in the surroundings and is rapidly attenuated, so that only a relatively short reach can be obtained. When the influence of the stationary air is reduced by the sub nozzle 23, the attenuation of the high speed air from the blowing nozzle 9 which is the main nozzle is reduced, the reaching distance is extended, and the high speed air becomes planar as a whole. As a result, the hand can be dried even at a position away from the air outlet 10, and the ease of use and the improvement of the drying function can be achieved. Since the other functions are the same as those of the third embodiment, the description thereof will be omitted.

Example 5. In this embodiment, the blowing nozzle 9 of the air jet drying apparatus for drying the hand shown in the third or fourth embodiment is used.
It is configured obliquely toward the front. Therefore, except for the configuration related to the blow-out nozzle 9, it is the same as that of the third and fourth embodiments, and the same parts as those are denoted by the same reference numerals in the drawings and their description is omitted.

FIG. 8 shows an air jet drying apparatus of the fifth embodiment. In the air jet drying apparatus of this embodiment, the blowing nozzle 9 is obliquely arranged on the front side, which is the user side, so that high-speed air is blown obliquely forward from the outlet 10. It may be configured with a single blow-out nozzle 9 as in the third embodiment, or may be used as a main nozzle as in the fourth embodiment, and another linear blow-out port 22 may be provided at a depth of 50 mm to 70 mm from the main nozzle. Sub nozzle 23 with
May be provided. In this case, the sub nozzle 2
Similarly, 3 is also inclined diagonally to the front side.

By inclining the blow-out nozzle 9 obliquely to the front side, the blowing direction of the high-speed air is directed toward the front of the body shell 1, and the hand drying process is performed at a position where the body shell 1 does not obstruct the visual field. be able to. As a result, the user can naturally carry out the hand drying process by extending his or her hand as if the user were to wash his or her hand by hand, for example, to the faucet of the tap, which improves usability.
The other functions are the same as those of the third or fourth embodiment, and the description thereof will be omitted.

Although most of the above embodiments have been described with respect to the air jet drying device for drying the hand, the present invention can be applied to various drying target drying devices in the basic configuration. For example, it can be used for a dry treatment of hands and feet around a food manufacturing site and a dry treatment after washing of used equipment.
