DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washing apparatus for washing various articles such as vehicles, including dishes, foods, hands, and the like.

[0002]

2. Description of the Related Art Some cleaning devices include, for example,
As disclosed in Japanese Patent No. 86274, there is an apparatus in which a liquid cleaning medium in the form of droplets or mist is ejected from a cleaning nozzle in an extremely high-speed air flow. As shown in FIGS. 21 and 22, the cleaning nozzle of this type of cleaning device is connected to a low-pressure gas supply source 101 composed of a roots blower by a gas transfer path 102. Gas transfer path 102
Is sent from the cleaning nozzle 103 at a high speed and a large flow rate. A liquid cleaning medium is supplied to the cleaning nozzle 103 from the cleaning medium supply unit 104, and as shown in FIG. 22, a gas-liquid mixed jet composed of a high-speed droplet flow and a high-speed air flow is generated in the nozzle head of the cleaning nozzle 103. Is done. This type of cleaning device can realize a high air flow velocity of about 200 m / s at the maximum, and the air flow velocity of about 200 m / s allows a liquid cleaning medium mixed in a droplet form to have a flow rate of 200 m / s.
Cleaning with a droplet speed of about s is possible, and dirt attached to products in the manufacturing process of electronic components and precision machines can be removed without using chlorofluorocarbon or the like.

[0003]

In the conventional cleaning apparatus described above, the fluid resistance of the nozzle head line and the tip of the nozzle head, which is the fluid outlet, depends on the gas-liquid mixing ratio, and is (liquid amount) / (liquid amount). The fluid resistance increases with an increase in the amount of gas. This is because the fluid resistance of the pipe or the fluid outlet is proportional to the specific gravity of the fluid. For example, when water having a specific gravity of 1000 times that of air is mixed into the nozzle head by 1% by volume, the air fluid 1 + 1000 × 0.01 =
11 times the fluid resistance will be generated. Therefore, when the supply amount of the liquid cleaning medium is changed, the fluid resistance of the nozzle head changes greatly.In order to maintain the jet speed of the gas-liquid mixed jet at a speed at which the gas can be washed, the gas flow rate should be kept constant. In order to maintain the power, it is necessary to control the power of the low-pressure gas supply source 101 according to a change in the fluid resistance of the nozzle head, which is a factor that complicates the configuration.

Further, when the liquid cleaning medium stays in the nozzle head, such as at the start of operation, or when a large amount of the liquid cleaning medium is supplied to the nozzle head, a low-pressure gas supply source 10 is provided.
1 does not provide the amount of air for self-cooling, so that there is a problem that a failure due to overheating of the low-pressure gas supply source 101 is likely to occur. In addition, the liquid cleaning medium supplied to the nozzle head has Since it is necessary to apply a pressure that overcomes the fluid resistance of the portion and a pressurizing pump for pressurizing and supplying the liquid cleaning medium is required, the apparatus is expensive.

There are several other problems associated with supplying a liquid cleaning medium into the nozzle head. For example, when the low-pressure gas supply source 101 stops during the supply of the liquid cleaning medium, the liquid cleaning medium is filled in the nozzle head and flows backward to the gas transport path 102 and further to the low-pressure gas supply source 101 side. It includes the possibility. When the liquid cleaning medium enters the low-pressure gas supply source 101 through the gas conveyance path 102, the blades of the low-pressure gas supply source 101 may be damaged, or may cause a short circuit. Another problem is that scales and mold are easily generated inside the cleaning nozzle 103 or inside the gas transfer path 102 where the liquid cleaning medium may enter due to long-term use, which may cause an unpleasant odor. Maintenance of the inside of the cleaning nozzle 103 and the inside of the gas transfer path 102 must be periodically performed for cleaning and cleaning in order to become a breeding nest of bacteria. in this way,
By supplying the liquid cleaning medium to the nozzle head communicating with the gas transfer path 102, not only is the reliability of the apparatus lowered, but also the need for maintenance is increased.

The present invention has been made in order to solve the above-mentioned conventional problems, and an object thereof is to obtain a simple cleaning device having a structure capable of efficiently cleaning dirt in a short time. The purpose is to improve the reliability, usability, and functions of the device.

BEST MODE FOR CARRYING OUT THE INVENTION

Embodiment 1 FIG. FIG. 1 is a perspective view showing the cleaning device of the first embodiment with a part thereof cut away, and FIGS. 2 and 3 are cross-sectional views of main parts. This washing apparatus is mainly configured as a dishwashing apparatus for washing cooking utensils, dishes and the like. In this cleaning device, the core part that performs the cleaning function is:
A blower system 1 for generating a high-speed airflow and ejecting it to the outside, a cleaning liquid supply system 2 for supplying a cleaning liquid to the high-speed airflow immediately after the ejection,
An accelerator 4 for accelerating the supplied cleaning liquid by a high-speed airflow from the airflow jet nozzle 3 to generate a droplet flow.

The blower system 1 is configured to send the blown air from the blower 5 to the airflow nozzle 3 through a gas flow path to generate a high-speed airflow and blow it out. 6 is mounted. The gas flow path is constituted by an air supply pipe 7 communicating between the blow-off side of the blower 5 and the air flow ejection nozzle 3, and the air supply pipe 7 is constituted by, for example, a vinyl pipe having elasticity and flexibility. The cleaning liquid supply system 2 is configured to supply a cleaning liquid such as tap water, for example, to a liquid nozzle 9 which is a supply unit disposed in the vicinity of the ejection port 8 of the airflow ejection nozzle 3. Flow path 10 formed of a vinyl or metal pipe connecting the liquid nozzle 9 with the water nozzle 9 and a water source such as a water pipe or a faucet and the flow path 10 between the liquid nozzle 9.
Between the constant flow valve 11 and the motor-operated valve
2 are provided.

As shown in FIGS. 2 and 3, the accelerator 4 has a wall structure which does not obstruct the path of the air flow along the traveling direction of the air flow ejected from the air flow jet nozzle 3, and has an acceleration wall 13 facing the air flow. The liquid nozzle 9 is integrally formed near the jet port 8 of the airflow jet nozzle 3 of FIG. The supply port 14 of the liquid nozzle 9 is formed as a row of small holes formed in the acceleration wall 13 in a direction substantially perpendicular to the traveling direction of the air flow along the jet port 8 of the air jet nozzle 3. The accelerator 4
May be configured separately from the liquid nozzle 9, and in this case, is configured as a wall surface structure that is connected to the supply port 14 of the liquid nozzle 9 in the traveling direction of the air flow. The cleaning liquid supplied to the accelerating wall 13 of the accelerator 4 moves while diffusing along the accelerating wall 13 due to the high-speed airflow from the air jet nozzle 3 flowing along the accelerating wall 13, and from the end of the accelerating wall 13 It is blown off and accelerated by the high-speed airflow to become a droplet flow at a speed close to the airflow. This droplet stream is mixed with the air stream to generate a gas-liquid mixed jet 15. In short, the high-speed gas-liquid mixing jet 1 generated through the accelerator 4
If the object 5 is caused to collide directly with the object to be cleaned, the cleaning device can perform a function of cleaning the object to be cleaned.

As a dishwashing apparatus, as shown in FIG. 1, a container provided with a washing space 18 having an opening 17 at an upper portion through which dishes (objects to be washed) such as dishes can be put in and taken out as objects 16 to be washed. A cabinet-type main body 20 to which a body 19 is attached is provided with an air blowing system 1, a cleaning liquid supply system 2, and an accelerator 4. The air jet nozzle 3 is formed in a fan shape, and a rectangular jet port 8 is disposed near the upper portion of one side of the container body 19 toward the washing space 18 so as to be longer in the vertical direction. Detecting means 21 and 22 are provided near the opening 17 of the container body 19 to detect the object 16 to be cleaned, and detect that the object 16 to be cleaned is located in the cleaning space 18. A first detection signal is sent as a start detection signal. In response to the first detection signal, the control unit 23 performs an operation of driving the blower 5 and opening the electric valve 12 that shuts off the cleaning liquid. As the detecting means 21 and 22, for example, a photoelectric sensor or an ultrasonic sensor is used.

In the cleaning apparatus configured as described above, the object 16 to be cleaned is held by hand and the cleaning space 18 of the container 19 is held.
Next, the cleaning operation is performed by making the surface to be cleaned face the airflow jet nozzle 3. That is, when the cleaning object 16 held by the user is inserted through the opening 17 into the cleaning space 18,
The detecting means 21 detects the object 16 to be cleaned, and sends a first detection signal, which is a cleaning start detection signal, to the control unit 23. The control unit 23 receives the first detection signal and opens the electric valve 12 that shuts off the driving of the blower 5 and the cleaning liquid. As a result, gas (air) is taken into the blower 5 through the filter 6, and a high-speed airflow is injected from the airflow jet nozzle 3 through the airflow pipe 7. Is supplied to the liquid nozzle 9 through the constant flow valve 11 and the electric valve 12 at a constant flow rate. The cleaning liquid supplied from the liquid nozzle 9 moves to the accelerator 4 close to the liquid nozzle 9 by the action of airflow, and is accelerated and blown off by the high-speed airflow from the airflow ejection nozzle 3 in the accelerator 4 to be blown off. As a result, a gas-liquid mixed jet 15 mixed with the air flow is jetted onto the cleaning target 16 held in the cleaning space 18.

The gas-liquid mixed jet 15 jetted toward the washing space 18 collides with the object 16 to be washed, and acts as an impact force of a high-speed droplet flow and water flow, and a wiping action due to the collision of the high-speed air flow. Simultaneously. As a result, the dirt adhering to the object 16 to be cleaned is peeled off in a very short time, is washed away, is blown off, and is removed. The dirt-containing droplets are quickly pushed down by airflow along the surface of the cleaning object 16 to the end thereof, are separated from the cleaning object 16 and flow down to the bottom of the container body 19, and are drained from the drain pipe. You.

In the case where the object 16 to be washed is tableware, the speed of the air flow when jetting from the air jet nozzle 3 is preferably about 40 m / s or more from the viewpoint of cleaning performance. Is set at about 80 m / s or less. This value is such that the washing effect is sufficiently obtained, and the gas-liquid mixed jet 15 does not cause pain even if it touches the hand, and the washing can be completed in 3 to 10 seconds per dish without using a detergent. It is.

Even when the air flow speed is about 40 m / s or less, if the degree of dirt is light or tableware to which dirt, such as salad oil or meat sauce, which is relatively easily removed compared to butter, is used. It is possible to wash with a washing liquid without detergent. In addition, if the dishes are rubbed or a detergent is used in combination, the dishes can be washed even at a lower airflow. The flow rate of the cleaning liquid supplied from the cleaning liquid supply system 2 is
Generally, it is a flow rate (10 liters / minute or less) that can be supplied from water supply. In the first embodiment, a flow rate of 8 cubic meters / minute and a cleaning liquid of about 5 liters / minute are used.
A gas-liquid mixed jet 15 of about 0 m / s or less is generated and jetted.

When the cleaning of the object 16 by the gas-liquid mixed jet 15 is completed, the object 16 to be cleaned is once evacuated from the cleaning space 18. By this retraction operation, the detection signal from the detection means 21 is cut off, and the control unit 23 recognizes the user's intention to end the cleaning. That is, in response to the interruption of the detection signal from the detection means 21, the electric valve 12 is closed to stop the supply of the cleaning liquid and stop driving the blower 5.

Thereafter, the user reinserts the object 16 to be washed into the washing space 18, so that the detecting means 22 detects that the object 16 to be washed is located in the washing space 18. A second detection signal is sent as a start detection signal. The control unit 23 receives this second detection signal and drives only the blower 5. As a result, a high-speed airflow is jetted from the airflow jet nozzle 3 toward the cleaning space 18, and droplets attached to the cleaning target 16 are scattered and pushed to wipe off the cleaning target 16, thereby draining the cleaning target 16. . Since the force applied by the airflow to the droplet is superior to the surface tension of the droplet at the end of the object 16, the droplet is peeled off from the object 16 and drained.

When the object 16 to be washed is tableware, the wind speed required to dry it by draining it is 80, for example.
m / sec, but the air volume is, for example, 1 cubic m
/ Min. When the user removes the object 16 to be cleaned from the cleaning space 18 at the time when the draining is completed, the control unit 23 stops driving the blower 5 in response to the interruption of the second detection signal from the detection unit 22. .

As described above, in the cleaning apparatus according to the first embodiment, the cleaning liquid continuously supplied from the water source is accelerated by the accelerator 4 to become a gas-liquid mixed jet 15 and is jetted to the object 16 to be cleaned in the cleaning space 18. As a result, the dirt adhering to the article 16 to be cleaned is separated by the impact force of the sanitary gas-liquid mixing jet 15, falls by the flow of water, and is cleaned in a short time. Thus, the ability to wash various stains in a short time without using a detergent, the amount of water used is also small and hygienic, especially when the user has weak skin or skin disease Not only is it highly effective, it is also effective in terms of environmental protection.

Since the cleaning liquid supply port 14 is provided outside the air flow jet nozzle 3, the cleaning liquid is supplied after the gas is jetted from the air flow jet nozzle 3, so that the cleaning liquid is supplied to the inside of the air flow jet nozzle 3. The gas does not affect the cleaning liquid, and the flow resistance of the flow path and the tip portion (nozzle head) of the airflow jet nozzle 3 does not depend on the supply amount of the cleaning liquid. Therefore, even if the amount of the cleaning liquid is adjusted, the fluid resistance of the air jet nozzle 3 does not change, so that control for adjusting the power of the blower 5 according to the supply amount of the cleaning liquid is not required, and the configuration is simplified. Further, since it is not necessary to supply the cleaning liquid by overcoming the gas pressure in the air flow jet nozzle 3, a pressure pump or the like which has been conventionally required is not required, and the configuration of the cleaning apparatus is simplified and inexpensive.

The detecting means 21 and 22 are provided for the object 16 to be cleaned.
Are connected so as to detect different predetermined positions in the washing space 18 and to send separate detection signals to the control unit 23, so that the user wants to wash or drain. Can be determined. Although the operation can be automatically controlled based on the cleaning time and the blowing time, the degree of contamination of the object 16 to be cleaned generally varies, so that it is more efficient for the user to determine the completion of the cleaning than to determine the completion of the cleaning. .

Further, by making the number of revolutions of the blower 5 variable by the control unit 23, even if the amount of the cleaning liquid is adjusted, the fluid resistance of the air jet nozzle 3 does not change.
The speed of the gas-liquid mixing jet 15 corresponding to the rotation speed of the gas-liquid mixing jet 15 can be obtained.
The speed and the form of the droplets can be adjusted, and a highly responsive cleaning device can be constructed. On the other hand, since the blower 5 cools the internal motor by the gas blown by itself, it is necessary to secure a constant air volume from the viewpoint of the reliability of the device. Even if the liquid amount is adjusted, the fluid resistance of the airflow jet nozzle 3 does not change. Therefore, even if the liquid amount is changed freely, the air volume does not decrease and the motor does not overheat. In addition, since the airflow jet nozzle 3 is separated from the liquid nozzle 9 for supplying the cleaning liquid and the accelerator 4, the cleaning liquid flows backward to the blower 5 even when the airflow from the airflow jet nozzle 3 is stopped. And a highly reliable cleaning device.

As described above, since the cleaning liquid does not enter the inside of the air jet nozzle 3 or the inside of the air supply pipe 7, scale or mold may be generated inside the air jet nozzle 3 or the inside of the air supply pipe 7. In addition, problems such as generation of an unpleasant odor and propagation of bacteria can be avoided, and maintenance such as cleaning and cleaning of the inside of the air jet nozzle 3 and the inside of the air supply pipe 7 is almost unnecessary.

In the first embodiment, since the cleaning device for cleaning tableware and the like is applied as an example, the container body 19 is used.
Although fresh water (tap water) which is easy to handle and use is used as a cleaning liquid, a general cleaning apparatus is a mechanism for forming a blowing system 1, a cleaning liquid supply system 2, and a gas-liquid mixing jet 15. The cleaning liquid is configured to be industrial water, pure water, or a CFC-based cleaning liquid according to the difference between the objects 16 to be cleaned and the type of dirt. Examples of the non-CFC-based cleaning liquid include an alcohol-based cleaning liquid and a terpene-based cleaning liquid.

The blower 5 may be of a type that blows air by a blower fan or a type that discharges air by pressurizing with a pump or the like. The gas-liquid mixing jet 15 may be generated by other gas.

Embodiment 2 4 to 6 show a main part of the cleaning apparatus according to the second embodiment. As can be seen from FIG. 4, this cleaning apparatus has the same basic configuration as that of the first embodiment except for the accelerator 4. Therefore,
The same parts as those in the first embodiment are described in the first embodiment.
The same reference numerals are used as in the first embodiment, and the description thereof is omitted.

The cleaning apparatus according to the second embodiment is provided at the terminal edge of the accelerating wall 13 of the accelerator 4 shown in the first embodiment in order to promote the acceleration of the cleaning liquid by an air current as shown in FIGS. The curved portion 24 is curved in a direction approaching the airflow side. Accordingly, the airflow flows close to the cleaning liquid moving along the acceleration wall surface 13, and acceleration of the cleaning liquid is promoted. In the accelerator 4, the gas flow accelerating the cleaning liquid is decelerated because energy is deprived by the cleaning liquid, and settles down to a speed represented by the following formula, and becomes a gas-liquid mixed jet 15 mixed with the droplet flow. The flow rate Qa of the airflow from the airflow jet nozzle 3
, The wind speed Va and the density ρa, the flow rate Qw of the cleaning liquid, the density ρw
Then, the flow velocity Vo of the gas-liquid mixed jet 15 after acceleration is approximately Qa × ρa × Va ² = (Qa × ρa + Qw × ρw)
× Vo ² .

The accelerator 4 further has a wall surface 25 facing the acceleration wall surface 13 with the airflow interposed therebetween. Acceleration wall 13
The distance A between the air flow jetting nozzle 3 and the wall 25 facing the air flow jetting nozzle 3 is greater than the opening width B of the jet port 8 of the air flow jetting nozzle 3.
And between the wall surface 25. On the other hand, the distance C between the acceleration wall surface 13 and the wall surface 25 on the side far from the airflow ejection nozzle 3 is less than or equal to the distance A on the side near the airflow ejection nozzle 3, and the cleaning liquid in which the airflow moves along the acceleration wall surface 13. . The wall surface 25 can prevent the cleaning liquid from moving along the acceleration wall surface 13 by the air flow, and can prevent movement of the air flow from moving away from the acceleration wall surface 13, so that the function of generating the droplet flow becomes more stable.

Since the cleaning liquid supplied from the liquid nozzle 9 integrated with or separate from the accelerator 4 is accelerated along the accelerating wall 13 to form a high-speed droplet flow, the shape of the accelerating wall 13 is adjusted to the object 16 to be cleaned. By making the surface curved, the gas-liquid mixed jet 15 having an efficient shape can be formed, and the cleaning efficiency can be improved. For example, when the distance between the acceleration wall surface 13 and the wall surface 25 on the outlet side is increased, the gas-liquid mixed jet 15 diffuses in a fan shape with a large angle, and when the distance is reduced, the gas-liquid mixed jet 1
5 will gradually gather on the downstream side. Also, the wall 25
When the length of the gas stream in the traveling direction is increased, the droplet diameter of the droplet stream of the gas-liquid mixed jet 15 increases, and the impact force increases.

As described above, the shape and length of the accelerator 4 formed by the acceleration wall surfaces 13 and 25 contribute to the shape and properties of the gas-liquid mixing jet 15. Therefore, as shown in FIG.
The wall 25 is pivotally supported by the operation of the knob 26 so that the gap between the acceleration wall 13 and the outlet side can be adjusted. It becomes possible to adjust to a shape suitable for cleaning, and the cleaning function is expanded.

As described above, according to the second embodiment, the airflow from the airflow jet nozzle 3 can be efficiently used for accelerating the cleaning liquid, and not only can the size of the cleaning apparatus be reduced, but also the size of the cleaning apparatus can be reduced. Since the energy of the airflow can be used efficiently, the operating cost can be reduced. Further, since the required cleaning performance is obtained by the required minimum airflow and the required minimum wind speed, noise can be reduced, and the airflow not used for accelerating the cleaning liquid collides with the object 16 to be cleaned. Thus, the mist of the atomized cleaning liquid can be prevented from scattering around. Other functions and advantages are the same as those of the first embodiment.

Embodiment 3 FIG. 7 is a perspective view showing a main part of the cleaning apparatus according to the third embodiment. As can be seen from FIG. 7, this cleaning apparatus has the same basic configuration as that of the first embodiment except for the accelerator 4. Therefore, the same portions as those of the first embodiment are denoted by the same reference numerals as those of the first embodiment, and description thereof will be omitted.

In the cleaning device of the third embodiment, the accelerator 4 shown in the first embodiment has a cylindrical structure surrounding the airflow. As shown in FIG. 7, the accelerator 4 has an acceleration wall 13 that surrounds the flow path of the airflow from the airflow jet nozzle 3.
And a wall surface 25 opposed thereto and two other wall surfaces 27,
28. The airflow jetted from the airflow jet nozzle 3 is divided into the acceleration wall surface 13 and the other three wall surfaces 25 and 2.
The cleaning liquid is supplied through the inside of a cylindrical structure surrounded by 7, 28, and in this cylindrical structure.

The gas inlet of the accelerator 4 is formed in a shape substantially similar to the shape of the jet port 8 of the gas jet nozzle 3 so that the gas from the gas jet nozzle 3 can easily enter, and its plane area is equal to that of the gas jet nozzle. 3 is formed to have an area equal to or greater than the plane area of the ejection port 8. The inlet side of the accelerator 4 is provided with a bell mouth portion 29 for facilitating the introduction of an airflow, and the outlet area of the accelerator 4 is configured to be larger than the inlet area so as not to cause a fluid resistance of the passing airflow.

The accelerating wall 13 and the opposing wall 25
Is set to be smaller than the interval on the side close to the airflow jet nozzle 3 so that the airflow approaches the cleaning liquid moving along the acceleration wall surface 13. For this reason, the interval between the other two wall surfaces 27 and 28 is larger at the exit than at the entrance to make the area of the exit larger than the area of the entrance. The cross-sectional shape of the accelerator 4 is determined by what kind of shape of the gas-liquid mixing jet 15 is optimal according to the object 16 to be cleaned, and may be rectangular or oval as shown in the drawing. Furthermore, it may be shaped like a crescent.

By configuring the accelerator 4 in this manner, the direction of the air flow jetted from the air flow jet nozzle 3 in the accelerator 4 is regulated, and the cleaning liquid is accelerated by the air flow whose direction is regulated, and the gas-liquid The mixed jet 15 can be focused and collided with the object 16 to be cleaned without diffusing,
Strong peeling force can be obtained.

As shown in FIG. 8, the air jet nozzle 3 has an uneven surface 30 near the jet port 8 through which the air flow passes.
By forming the cross-sectional shape into a chrysanthemum flower shape or the like, a low-speed airflow is formed by the uneven surface 30 around the high-speed airflow in the center, and the high-speed airflow in the center and the peripheral airflow are formed. It is possible to suppress the generation of noise due to the disconnection with the airflow near the stop state. When such a configuration is adopted, the shape of the inlet of the accelerator 4 is not made to be similar to the shape of the ejection port 8 of the airflow ejection nozzle 3 and the
It is more effective to adopt a cross-sectional shape that includes the ejection port 8 of the above.
In order to reduce the noise of the air flow jet nozzle 3, it is effective to provide a small jet hole around the jet port 8, or to provide a ring having the same shape as the jet port 8 in front of the air jet nozzle 3. Other basic functions are the same as those of the first and second embodiments.

Embodiment 4 FIG. 9 is a perspective view showing a main part of a cleaning apparatus according to the fourth embodiment. As can be seen from FIG. 9, the basic configuration of this cleaning device is the same as that of the first, second, and third embodiments. Therefore, the same portions as those of the first, second, and third embodiments are denoted by the same reference numerals as those of the first, second, and third embodiments, and description thereof is omitted.

The direction in which the cleaning liquid is supplied to the accelerator 4 is substantially perpendicular to the direction of the flow of the air flow from the air flow jet nozzle 3, so that the air flow from the air flow jet nozzle 3 affects the supply amount of the cleaning liquid. The supply amount Q of the cleaning liquid is determined by the head H applied to the cleaning liquid and the minimum sectional area S of the flow path of the cleaning liquid.
Is approximately determined by Q = S × √ (2 × g × H) (g is a gravitational acceleration). Supply port 1 for cleaning liquid to accelerator 4
In the case where the supply amount is small, if the supply is to be performed using a single hole, the supply hole for the cleaning liquid is clogged with scale, etc., so that the hole diameter increases, but this requires a wide range. The cleaning liquid cannot be supplied. For this reason, in the fourth embodiment, the supply port 14 of the liquid nozzle 9 to the cleaning liquid accelerator 4 is constituted by a plurality of small holes arranged along the ejection port 8 of the airflow ejection nozzle 3, The cleaning liquid can be supplied to a much wider range than the supply hole.

The accelerator 4 has a liquid nozzle 9 in which supply ports 14 are formed in multiple stages (two stages in FIG. 9) at a distance in the direction of the flow of the airflow from the airflow jet nozzle 3 and are formed integrally or separately. ing. The cleaning liquid supplied from the upstream supply port 14 and the cleaning liquid supplied from the downstream supply port 14 combine with each other in the course of being accelerated by the airflow from the airflow jet nozzle 3 in the accelerator 4 to form a large liquid. It becomes a gas-liquid mixed jet 15 containing a cleaning liquid having a droplet diameter, and the impact force when colliding with the object 16 to be cleaned is increased, so that a large cleaning power is obtained.

In the middle of the water flow path 10 connecting the electric valve 12 of the cleaning liquid supply system 2 and the supply part to the accelerator 4, the cleaning liquid is once discharged from the supply pipe 31, and introduced again into the supply pipe 32 of another system. A water storage tank 34 for temporarily storing the cleaning liquid that has passed through the discontinuous point 33 is provided above the supply unit. Supply pipe 31
A constant flow valve 11 is mounted in the middle of the flow so that the fluctuation of the supply pressure of the upstream cleaning liquid does not affect the gas-liquid mixing jet 15. As a result, the cleaning performance does not change even when the supply pressure of the upstream cleaning liquid changes.

The supply parts for the motor-operated valve 12, the water storage tank 34, and the accelerator 4 are arranged close to each other.
A supply pipe 32 for the cleaning liquid between the supply unit 4 and the supply unit is
And the shortest path that connects the supply section linearly. Thereby, the supply of the cleaning liquid is stopped by closing the electric valve 12, and the cleaning space 1 of the container 19 is
When the droplets on the surface of the object 16 to be washed are scattered and drained by the force of the air current ejected toward the nozzle 8, the washing liquid remaining in the supply pipe 32 is discharged (supplied) in the shortest time, Draining can be started in a short time, and as a result, the draining is completed in a short time. For example, if the flow path between the water storage tank 34 and the supply unit is trapped, the cleaning liquid remaining in the trap can be continuously supplied to the accelerator 4 in small amounts for a while. Is mixed, so that draining cannot be completed in a short time.

FIG. 10 shows the configuration around the accelerator 4 which can complete the draining in a shorter time. That is,
The supply unit for supplying the cleaning liquid in the accelerator 4 is provided with an uneven portion 35.
The uneven portion 35 is provided such that the direction of the supply port 14 is at an acute angle with respect to the traveling direction of the airflow from the airflow jet nozzle 3. According to this configuration, the air jet nozzle 3
The cleaning liquid is attracted and the supply is promoted by the flow of the airflow from, so that the cleaning liquid remaining in the supply pipe 32 can be discharged (supplied) in a shorter time. Other basic functions are the same as those of the first, second, and third embodiments.

Embodiment 5 11 and 12 are perspective views showing a main part of a cleaning apparatus according to the fifth embodiment. FIG.
As can be seen from FIG. 1, the basic configuration of this cleaning device is the same as that of the first, second, and third embodiments. Therefore,
The same parts as those in the first, second, and third embodiments are denoted by the same reference numerals as those in the first, second, and third embodiments, and description thereof is omitted.

The fan-shaped gas jet nozzle 3 gradually reduces the gas passage cross-sectional area from its gas flow path toward the jet port 8 and expands in the fan-shaped angular direction. Shape. Thereby, the jet direction of the air current from the air jet nozzle 3 becomes radial. Sectional area passage of the air flow, for example, as the pressure of the air flow is increased in proportion to the distance X from the ejection port 8 of the air jet nozzle 3, the cross-sectional area S S ² = So. ²
× Si ² × Xm / ｛(So ² −Si ² ) × X + Si ² × X
m}. Here, Si is the cross-sectional area of the gas flow path, So is the cross-sectional area of the jet port 8 of the air flow jet nozzle 3,
Xm indicates the length of the ejection port 8 of the airflow ejection nozzle 3 (see FIG. 12).

On the other hand, the accelerator 4 accelerates the cleaning liquid radially while maintaining the advancing direction of the radial airflow jetted from the airflow jet nozzle 3 so that the gas-liquid mixed jet 15 is jetted radially. , The fan shape is expanded in accordance with the traveling direction of the airflow. As shown in FIG. 11, since the surface of the accelerator 4 to which the cleaning liquid is supplied is substantially perpendicular to the opening plane of the opening 17 of the container body 19 into and out of the object 16 to be cleaned, The mist of the cleaning liquid generated when the object collides with the object to be cleaned 16 and is subjected to the cleaning is changed into the mist of the cleaning liquid farther from the opening 17 by the opening 1.
The gas-liquid mixing jet 15 on the side closer to 7 is blocked, so that the mist does not easily come out of the opening 17. Also,
The jet direction of the air current from the air jet nozzle 3 is determined by the opening 17.
Because it points to the inside of the washing space 18 without pointing to
The gas-liquid mixed jet 15 that has not collided with the cleaning target 16 collides with the wall surface of the cleaning space 18 and does not jump out of the opening 17 to the outside. As described above, in the cleaning device according to the fifth embodiment, since the mist of the cleaning liquid that jumps out of the opening 17 of the container 19 can be suppressed, the periphery of the device can be kept clean and sanitary. Since the gas-liquid mixed jet 15 can be radiated at a wide spray angle, a wide cleaning range can be covered, and the cleaning target 16 can be efficiently cleaned in a short time.

As shown in FIG. 13, the surface of the accelerator 4 for supplying the cleaning liquid is connected to the opening 1 through which the object 16 to be cleaned is put in and out.
7, the object to be cleaned 1
The object 16 to be washed can be washed only by inserting the member 6 into the washing space 18 through the opening 17 and then withdrawing the object, and it is not necessary to check the washing state, thereby improving the operability.

The airflow jet nozzle 3 is provided with a pressure transmission pipe 37 as an airflow vibration means for connecting the flow path on the supply port 14 side and the flow path on the supply port 36 side, and the airflow from the jet port 8 is supplied by the pressure transmission pipe 37. It vibrates periodically to the port 14 side and the supply port 36 side. Due to the vibration of the airflow, the supply of the cleaning liquid to the supply port 14 side and the supply to the supply port 36 side are repeated periodically. That is, the gas-liquid mixed jet 15 becomes an intermittent jet, a larger impact force is obtained as compared with a continuous jet, and dirt can be more strongly peeled and washed.

The intermittent jet having a high cleaning effect can also be formed by the air jet nozzle 3 having the structure shown in FIG. That is, the flow path in the airflow jet nozzle 3 is branched into a plurality from the middle, and the jet ports 8 are provided in parallel at the ends of each flow path. A shielding plate 38 is provided at a branch portion of the flow path as air vibration means of the flow path, and the shielding plate 38 rotates according to the speed of the air flow, and functions to vary the flow distribution of the air flow to each flow path. . Thereby, the gas-liquid mixed jet 15 of the intermittent jet can be formed. Further, depending on the supply position of the cleaning liquid, the gas-liquid mixed jet 15 can be radiated at a wide injection angle with a small flow rate of air, and a wide cleaning range can be covered, so that the object 16 to be cleaned can be efficiently cleaned in a short time. be able to.

An intermittent jet having a higher cleaning effect is shown in FIG.
As shown in the figure, it can also be formed by the configuration on the accelerator 4 side.

5 are formed.
