Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a particle jet type washing apparatus, and more particularly to a particle jet type washing apparatus which can be suitably used as an apparatus for washing the body of an elderly person requiring care.

[0002]

2. Description of the Related Art With the advent of a rapidly aging society in recent years, the number of elderly people requiring care is increasing year by year, but bathing is one of the major problems in the care of elderly people. Conventionally, as a method of washing the body of such an elderly person when taking a bath, there are a method of rubbing the body with a towel, a method of spraying shower water on the body, a method of fluidizing slurry to wash the body, and the like. However, each of these methods has advantages and disadvantages due to the inconvenience that the caregiver takes a lot of time, the cleaning effect is insufficient, etc. The reality is that there is currently no cleaning device that can satisfy both elderly people.

In view of such circumstances, the applicant of the present invention has previously proposed, in Japanese Unexamined Patent Publication No. 2001-95880, a cleaning device that can be suitably used for cleaning the body of an elderly person. This device jets the particles into a jet and collides them with the user's body. Since the particles have a large frictional collision effect on the skin, an excellent cleaning effect can be obtained and the caregiver's labor It was a very excellent device that can significantly reduce

However, this body washing device also has the following problems. When using this particle jet type body cleaning device, the particles are blown up upward with vigorous force, so the upper part of the cleaning tank is closed with a lid to prevent the particles from jumping out of the cleaning tank. , The user puts the top of the neck over the top of the lid and enters the washing tank. Then, with the lid closed, the particles are jetted by ejecting gas into the cleaning tank, but the pressure in the cleaning tank becomes higher than the outside air due to the ejection of gas, so Some of them sometimes complained of pressure on their bodies.

Further, since the pressure inside the cleaning tank becomes higher than the outside air, the lid easily comes off. Therefore, it is necessary to make the structure for attaching the lid to the cleaning tank complicated and strong. Further, since the pressure in the cleaning tank was higher than the outside air, it was easy for particles to fly out from the holes provided in the lid. Therefore, the inner peripheral surface of the hole must be closely attached to the neck of the user, and the user sometimes feels cramped around the neck.
Further, the gas ejected from the bottom of the cleaning tank is curved by the Coanda effect (wall surface effect) and flows along one wall surface of the cleaning tank, so that the distribution of particles in the cleaning tank becomes uneven. I was not able to wash the user's body evenly. Regarding the problem due to this Coanda effect, the applicant of the present invention first applied for the patent application 2000-3.
Although it is possible to solve the problem by combining the jet oscillating mechanism proposed in Japanese Patent No. 46464, there is a drawback that the apparatus becomes complicated.

[0006]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and can be used comfortably without giving the user's body an uncomfortable feeling such as a feeling of pressure or cramping. In addition, the lid mounting structure can be simplified, and the distribution of particles can be made uniform with a simpler configuration, and the user's body can be evenly and reliably washed. It is an object of the present invention to provide a possible particle jet type cleaning device.

Further, a cyclone or a mist catcher (16) is provided between the blower (12) and the intake port (4), and foreign matters such as dust and water contained in the gas are introduced into the blower (12). It is supposed to be captured before.

An air supply port (6) for introducing outside air into the tank is provided at the bottom and side of the cleaning tank (1). An air supply pipe (23) communicating with the outside air is connected to the air supply port (6), and when the inside of the cleaning tank (1) becomes a negative pressure state by the drive of the blower (12), the air supply pipe (23).
The outside air is taken in from the end of the and is introduced into the air supply port (6). Then, the outside air introduced from the bottom of the cleaning tank (1) plays a role of blowing up the particles (2) upward to form a jet, and the outside air introduced from the side portion of the cleaning tank (1) is
It plays the role of colliding the granules (2) from the front and back of the body of the user (H). Further, the air supply pipe (23) is provided with a heater (1
7) is in communication with the outside air, and a steam pipe for flowing steam generated from the steam boiler (18) is connected between the heater (17) of the air supply pipe (23) and the air supply port (6). The outside air introduced from the end of the air supply pipe (23) is warmed by the heater (17), mixed with water vapor, and then introduced into the cleaning tank (1).

A midsole plate (5) having an opening through which the granules (2) can pass is disposed slightly above the bottom surface of the washing tank (1). The insole plate (5) is a plate on which the user (H) rides, and is composed of, for example, a wire mesh.

Between the inner bottom plate (5) and the bottom of the cleaning tank (1), a gas blow-out portion is provided for jetting the particles (2) into the cleaning tank (1) by jetting the gas. (7)
Are formed. FIG. 2 is a diagram in which the vicinity of the gas blowing portion (7) is extracted, and FIGS. 3 and 4 are perspective views showing an example of the configuration of the gas blowing portion (7). The gas blowing part (7) has an opening plate (8) having an opening through which the granules (2) cannot pass but gas can pass, and an inclined surface (9) adjacent to the opening plate (8). And a standing plate (91) which is vertically erected from the lower end of the inclined plate (9) to the surface of the opening plate (8). The inclined plate (9) is formed by the opening plate (8). Is inclined towards.

In the present invention, the method of providing the opening of the gas blowing portion (7) is not particularly limited, but typical examples are shown in FIGS. 3 and 4. The gas blowing part (7) shown in FIG. 3 is formed by the hypotenuses of triangular columnar members whose inclined surfaces (9) are arranged in parallel and at a distance from each other, and a strip-shaped opening plate ( 8) is provided, and in the case of this example, the opening is formed in a slit shape. The gas blowing part (7) shown in FIG. 4 is configured such that the four inclined surfaces (9) are inclined downward toward the four sides of the opening plate (8) having a quadrangular shape in plan view, In the case of this example, the openings are formed in the shape of holes.

The opening plate (8) is made of a wire mesh or the like which can be opened and closed by a hinge (10), and the granules (2) are provided on the upper surface thereof.
Is placed. The figure shows a state in which the aperture plate (8) is closed. In this state, the granules (2) cannot fall below the aperture plate (8), but the hinge plate (10) serves as a fulcrum to support the aperture plate (2). By rotating 8) downward, the granules (2)
Will fall toward the bottom of the cleaning tank (1).

The inclination angle (θ) of the inclined surface (9) is larger than the static friction angle (repose angle) of the granules (2), so that it falls on the inclined surface (9). The granules (2) drop quickly and reliably onto the aperture plate (8) and are immediately blown up again by the gas taken in through the air supply port (6).

The greatest feature of the cleaning apparatus according to the first embodiment is that, as a conventional method, the particles (2) are spouted in the cleaning tank (1). The point is that a method of taking in outside air by sucking the gas out of the cleaning tank (1) to bring it into a negative pressure state is adopted instead of the method of supplying the gas by pressure to the chamber. That is, in the cleaning apparatus of the first embodiment, the inlet (4) is provided in the upper lid (3) that closes the upper part of the cleaning tank (1), and the air supply port (6) is provided in the bottom of the cleaning tank (1). By sucking the gas in the cleaning tank (1) from the intake port (4), the inside of the cleaning tank (1) is made into a negative pressure state and the outside air is taken in from the air supply port (6), whereby the cleaning tank (1) Inside, a flow of gas from the bottom to the top is formed to jet the granules (2).

By adopting such a configuration, the pressure in the cleaning tank (1) is always lower than the outside air (atmospheric pressure), and therefore, the user's body is not squeezed and the elderly person is not affected. Even if there is, it becomes possible to use it comfortably. In addition, since the pressure in the cleaning tank (1) is lower than the outside air, the upper lid (3) is constantly pressed by the outside air and is unlikely to come off during use. It can be very simple. Also,
Since the pressure in the cleaning tank (1) becomes lower than the outside air, the granules (2) are less likely to be ejected to the outside from the hole provided in the upper lid (3) in order to put the upper part of the user's neck into the cleaning tank. It is possible to loosen the degree of adhesion of the user around the neck, and it is possible to eliminate the cramping feeling that the user feels around the neck with conventional devices.

FIG. 5 is a sectional view showing a second embodiment of the cleaning apparatus according to the present invention. Since the basic configuration of the cleaning device of the second embodiment is the same as that of the first embodiment, the same reference numerals are given to the same configurations and the description thereof will be omitted. Only different configurations will be described below. The cleaning device of the second embodiment,
Similar to the device of the first embodiment, as a method for making the granules (2) into a jet in the cleaning tank (1), a conventional method of feeding gas under pressure into the cleaning tank (1) is used. Without
The method is characterized in that a method of sucking gas from the inside of the cleaning tank (1) to bring it into a negative pressure state is adopted, but the gas supplied into the cleaning tank (1) is not the outside air but the intake port (4).
It is different from the device of the first embodiment in that it is the gas sucked from the device.

That is, in the cleaning apparatus of the second embodiment,
An intake port (4) provided in an upper lid (3) that closes the upper part of the cleaning tank (1) and an air supply port (6) provided in the bottom portion of the cleaning tank (1) are circulated through a circulation path (19). Gas in the cleaning tank (1) that has been suctioned from the intake port (4) and is supplied from the air supply port (6) through the circulation path (19). It is configured to form a flow of gas towards and to atomize the granules (2).

A blower (12) is connected to an intermediate part of the circulation path (19), and the blower (12) is driven to suck the gas in the cleaning tank (1) from the suction port (4) to suck it. The gas thus supplied is supplied into the cleaning tank (1) from the air supply port (6) through the circulation path (19).

The blower (12) and the intake port (4)
Cyclone or mist catcher between (16)
Is provided so that foreign matters such as dust and water contained in the gas are trapped before being introduced into the blower (12). In addition, a heater (17) is provided between the blower (12) and the air supply port (6), and a steam boiler (18) is provided in a passage connecting the heater (17) and the air supply port (6). ) Is connected to a steam pipe, and the gas passing through the blower (12) is heated by a heater (1
After being heated by 7), it is mixed with steam and introduced into the washing tank (1).

The passage connecting the heater (17) and the air supply port (6) is branched, and the branch pipe is the ejector (1).
It is connected to the particle collection tank (14) via 3). The ejector (13) is connected to an openable / closable particle discharge port (15) provided at the bottom of the cleaning tank (1), and when the particle discharge port (15) is opened, the inside of the cleaning tank (1) is closed. The granules (2) are sucked along with the flow of gas toward the granule collection tank (14), taken out from the granule discharge port (15) and collected in the granule collection tank (14). It

In the apparatus of the second embodiment, since the gas in the cleaning tank (1) is sucked from the intake port (4), the inside of the cleaning tank (1) is in a negative pressure state, and the first embodiment described above is used. It is possible to exert the same action and effect as. Also,
In this second embodiment, from the intake port (4) to the cleaning tank (1)
By adopting a configuration in which the gas inside is sucked and circulated to the air supply port (6), the following excellent operational effects can be exhibited. First, since the inside of the cleaning tank (1) is in a negative pressure state close to the atmospheric pressure, the user's body is hardly burdened. Further, since the gas sucked out from the cleaning tank (1) can be introduced into the blower (12) by utilizing its momentum and directly sent to the air supply port (6),
The power of the blower (12) can be greatly reduced. Moreover, since the gas once warmed by the heater (17) is circulated and used, the heat quantity required for warming the gas can be small, and the power of the heater (17) can be greatly reduced.

As described above, the cleaning apparatus of the second embodiment using the gas circulation system has many advantages as compared with the simple suction type apparatus of the first embodiment, but it uses the gas by circulating it. In consideration of hygiene, a sterilization mechanism is added to the circulation route piping. As the sterilization mechanism, as shown in FIG. 6, a nozzle (20) is arranged in the pipe of the circulation path (19), and the sterilizing agent and water contained in the sterilizing agent tank (21) are mixed to form the nozzle. The configuration of jetting from (20) into the pipe is preferably adopted.

Further, in the cleaning apparatus according to the present invention,
It is preferable to provide a direction control unit for controlling the jet direction of the particles above the opening of the gas blowing unit (7). Figure 7
FIG. 4 is a schematic view showing the vicinity of the gas blowing section (7) and the direction control section, which is extracted and shown in the cleaning apparatus according to the present invention. In order to make the drawing easier to see, only one gas blowing portion (7) is shown, and the configuration other than the gas blowing portion (7) and the direction control portion is omitted. The direction control unit
A control plate (2) is disposed above the opening of the gas blowing portion (7) so as to face each other in parallel and sandwich the opening.
2).

The control plate (22) may be an iron plate or the like having no holes, but it is preferable that the control plate (22) is an opening plate such as a wire mesh having a large number of openings through which the particles (3) cannot pass. This is because by using the control plate (22) as an opening plate, it is possible to suppress the pressure loss of gas to be small.

The arrangement of the control plate (22) can be changed according to the shape of the opening of the gas blowing section (7). For example, when the shape of the opening is a slit as shown in FIG. As shown in FIG. 8, the two control plates (2
2) may be arranged to face each other along both sides of the slit. When the shape of the opening is a quadrangle as shown in FIG. 4, four control plates (22) are provided as shown in FIG. It suffices to arrange them by combining them into a truncated pyramid shape.

The distance (D) between the opposing control plates (22) is set to be equal to or larger than the width (d) of the opening as shown in FIG. This is the distance (D) between the control plates (22)
Is smaller than the width (d) of the opening, particles (2) that do not pass between the control plates (22) are generated, and the jet direction of the particles cannot be sufficiently controlled.

When mounting the control plate (22), the granules (2) falling on the inclined surface (9) are opened by the opening plate (8).
In order to guide it upward, it is necessary to provide a gap between the lower end of the control plate (22) and the inclined surface (9) so that the granules (2) can pass therethrough. (Note that this configuration is omitted in FIGS. 8 and 9.) As a method of attaching the control plate (22) in this way,
As shown in FIG. 10, a leg (24) extending downward is provided on the control plate (22), and the leg (24) may be fixed to the inclined surface by an arbitrary method such as screwing or welding. still,
FIG. 10 shows an example of fixing with screws.

It is generally known that when a gas jet has a gradient, the jet is deflected to the left or right along the wall surface, and this phenomenon is called the Coanda effect (wall surface effect). In the cleaning apparatus according to the present invention, since the opening of the gas blowing portion (7) is provided with a gradient, the distribution of the particles (2) in the cleaning tank is biased due to the Coanda effect as shown in FIG. Occurs, and a good cleaning effect cannot be obtained.

However, as described above, by providing the direction control section for controlling the jet direction of the particles above the opening of the gas blowing section (7), the particles blown up from the opening face each other in parallel. Control plates (2
It is guided vertically upward through the space between 2). As a result, even if the gas bends due to the Coanda effect, the granular material (2) rises to a position considerably above the cleaning tank in a substantially symmetrical manner as shown in FIG. 12, and an excellent cleaning effect can be obtained. Becomes In FIG. 12, the solid line shows the flow of gas and the broken line shows the flow of particles. In addition, the applicant of the present application first applied for a configuration in which such a direction control unit is provided.
It is also possible to combine the jet rocking mechanism proposed in No. 00-346464. A combination of the direction control unit and the jet oscillating mechanism makes the apparatus a little complicated, but it is preferable because an extremely excellent cleaning effect can be obtained.

As described above, according to the first aspect of the present invention, the pressure inside the cleaning tank is always lower than the outside air (atmospheric pressure), giving a feeling of pressure to the user's body. It is possible that even elderly people can use it comfortably. Further, since the pressure in the cleaning tank is lower than the outside air, the upper lid is less likely to come off during use, and the structure for attaching to the cleaning tank can be made very simple. Furthermore, since the pressure inside the cleaning tank is lower than the outside air, it is difficult for the granules to pop out to the outside, and the seal around the user's neck can be loosened. It is possible to eliminate the cramped feeling.

According to the invention of claim 2, in addition to the effect of the invention of claim 1, since the inside of the cleaning tank is in a negative pressure state close to the atmospheric pressure, the user's body is hardly burdened. Produce an effect. Further, the gas sucked from the cleaning tank can be circulated by utilizing its momentum and sent to the air supply port as it is, so that the power of the circulation blower can be greatly reduced. Furthermore, when heating the gas supplied into the cleaning tank with a heater, the gas that has been warmed is circulated and used, so the amount of heat required to warm the gas can be small, and the power of the heater can be greatly reduced. It will be possible. According to the invention of claim 3, it is possible to reduce the deviation of the particles in the cleaning tank due to the Coanda effect, and it is possible to obtain an excellent cleaning effect. According to the invention of claim 4, the pressure loss of gas due to the provision of the direction control unit can be suppressed low.
