It only refers to representative 'cleaning object' in which the apparatus according to the present invention is used,

The present invention can be used in various fields such as sneaker washing or bathroom cleaning as well as tableware, and should not interpret the protection scope of the present invention by limiting the selection of the term 'tablet'.

First, as shown in Figures 1 and 2, the automatic dishwashing apparatus (A) according to the present invention is largely a housing (H), a drive unit (M) including a motor 20 embedded in the housing, the drive Frame (F) rotated by the unit, it comprises a cleaning member (W) such as a scrubber mounted on the frame.

The outer shape of the housing (H) is shown in a simplified form in the figure, but the convenience of gripping. It may have various shapes in consideration of slip prevention, design elements, and the like.

The switch of the control unit C including the microcomputer C1 for controlling the motor M and the like is provided on the outer surface of the housing,

The switch can be introduced in various structures at various locations in consideration of convenience of operation, prevention of malfunctions during the cleaning process, and waterproofness.

Basically equipped with a main switch (Ca) for the power on / off and a sliding switch (Cb) for adjusting the rotational speed of the motor (M),

If necessary, the motor can be configured to operate when pressurized by hand when using the cleaning device so that it can be easily pressed while holding the housing for cleaning.

Various types of switches can be implemented in a structure surrounded by an elastomer or other synthetic resin coating on the outer surface for waterproofing.

Regarding the convenience of washing or portability, the housing (H) has a built-in rechargeable battery (B), so the automatic dishwashing device (A) can be used easily even when there is no power supply. Can be used by connecting.

In addition, ordinary batteries can be purchased and used. Instead of providing a separate internal space,

It is preferable that the rechargeable battery B is configured to be removable rather than fixed, so that the rechargeable battery B can be removed and a commercial battery can be put therein.

Furthermore, it is preferable to prevent the problem of waterproofness when connecting a commercial external power source. In the present invention, the cable (E) connection part, especially the consultation part of the housing (H), is inserted into the cable (E) insertion part 17a (Fig. 2, upper right) Is a structure that can be opened and closed by the cap (10).

The cable E insertion portion 17a is provided with a normal connecting terminal E1 (see the enlarged plan view in the upper right of FIG. 2),

When necessary, when the cable (E) is connected, the switch (Ca) is turned on to rotate the motor 20, and electricity is used for cleaning.

When the motor is not operated, it is preferable to configure the microcomputer C1 to switch to the internal battery B charging mode.

As can be seen in FIGS. 1 and 2, the cap 10 has a fixing piece 13B at the lower part of the cap when the cable E insertion part 17a is closed to the fixing groove 13b of the housing H body. It is fitted in an interference fit method to prevent random separation,

At the time of separation opening, the cap is easily opened by inserting a finger into the finger insertion groove 10a formed at the right position of the cap 10,

Open cap 10 is coupled to the housing (H) by a connecting string 11 (possible to introduce a variety of other connecting members) made of a synthetic resin material having a strong elasticity,

The fixing piece 13A of the upper part of the cap can be fixedly coupled to the fixing groove 13a on the left side of the housing so that it is not dirty and is not stuck in the washing process.

In addition, as can be seen in Figure 2, the lower surface of the cap is provided with a packing ring (15a), the coupling portion of the housing (H) is also provided with a packing ring (15b),

The two packing rings 15a and 15b are structured to interlock with each other when the cap is closed to ensure waterproofness.

As shown in Figure 2, when the cable (E) is plugged in the waterproof packing to form a cable (E) insertion portion (17a) around the connection terminal (E1) in particular in order to ensure the waterproofness in the cleaning process ( 17) (rubber or other elastomeric material) was introduced.

The cable (E) insertion portion (17a) of the waterproof packing 17 is particularly narrowed from the top to the bottom so that the cable is tightly clamped to the waterproof packing (17) insertion portion (17a) when the cable (E) is fully coupled Intrusion of water can be prevented.

In addition, in the present invention to prevent any separation of the cable (E) coupled during cleaning

A locking groove (Ea) is formed in the cable (E), and in the housing (H), a locking protrusion (18) carried by the spring (18b) is formed to be coupled to each other.

The inclined end portion 18a of the locking protrusion 18 has a structure in which the locking protrusion 18 can be naturally pushed to the right by the input force when the lower portion of the cage E is inserted.

If the right retraction of the locking protrusion 18 is necessary for cable separation, pressing the button 19 exposed to the outside causes the spring 19b to be compressed and the inclined end 18a of the locking pusher 18a which is inclined to be compressed. ) And pressurization is possible, the retraction of the locking projection 18 and the separation of the cable (E).

On the other hand, the housing (H) has a separate detergent container (D), the detergent is discharged to the end of the shaft 21 through the tube (D2) by the pumping means is supplied to the cleaning member.

The detergent container D is shaped to have a substantially hollow cylindrical shape so as not to interfere with the arrangement of other components (parts) while providing a compact structure as possible,

In the hollow part of the detergent container the insertion part 17a for the other components, in particular the cable E, is arranged,

It is preferable to have an inclined bottom portion which is concentrated to a portion connected with the tube D2 so that the detergent can be completely discharged.

The pumping means may use an electric pump, but for the simple configuration, the air is supplied to the detergent container D by introducing a manual pump D1 and repeatedly pressing a button that is supported by a spring.

The detergent may be discharged to the end of the tube D2 by the pressure of air.

The pump D1 may be opened to refill the detergent toward the opening.

If there is no air pressure inside the detergent container, the detergent is not discharged to the end of the tube (D2), it is not necessary to introduce a separate opening and closing means at the end of the tube (D2).

However, due to problems such as aging of the packing part, the confidentiality of the pipe where the detergent is stored and discharged may not be maintained due to the aging of the packing part.

In consideration of this, opening and closing means may be introduced.

Opening and closing means is made of a material that is elastic and coupled to the end of the tube, for example, is closed and closed if no external force is applied.

Introducing an exit member that opens when a certain external force is applied

When the air is supplied to the detergent container (D) by the pump (D1) it can be configured to allow a certain amount of detergent to open and discharge the outlet member by the pressure of the air.

Next, the drive unit M is composed of a motor 20 embedded in the housing H and a shaft 21 protruding outside the housing (lower).

The shaft 21 rotated by the motor has a detachable part to implement an easy replacement of the cleaning member and a random separation prevention function,

The detachable part of the shaft has a non-circular structure in order to prevent idling of the replaceable frame F, which allows introduction of various general commercial cleaning members as well as customized cleaning members.

In the drawings, the cross-sectional shape is hexagonal, but if necessary, the cross-sectional shape may be a half-moon shape or various other shapes.

In addition, in Fig. 1, the elements constituting the detachable portion shown are hooks 21A, and the hooks 21A embedded in the hollow portion of the shaft 21 are the locking protrusions 21a and the pressing protrusions 21b exposed on the shaft outer surface. In order to obtain elasticity for the engaging projection 21a and the pressing projection 21b from its unique material and shape, various elastic structures can be introduced as necessary.

The replaceable frame (F) is coupled to and detached from the detachable portion of the drive unit (M) shaft 21 through the fastening portion 37,

Basically, it has a hexagonal groove structure that fits the shaft shape,

The separation prevention groove 37a to which the pressing protrusion 21b of the hook 21A is coupled is formed on each side of the hexagonal portion of the fastening portion 37, so that the insertion of the hook pressing protrusion 21b when combined with the separation preventing function is arbitrary. It can be implemented at the same time so that it does not matter in the direction.

In addition, in the right middle plan view and the lower right front sectional view of FIGS. 1 and 1, the frame F has a lower plate 31 to which the cleaning member W is in contact, and an intermediate plate having a narrower cross-sectional area than the lower plate. Plate 33,

The term 'plate', including the upper plate 35, does not mean to strongly constrain the shape to some extent. For example, [A] of Figure 4 has a lower 'plate' (31A) protruding to increase the convenience of cleaning the corner portion of the cleaning object (P1), such as a pan,

As such, the upper and lower 'plate' should be selected as a term arbitrarily selected for convenience of explanation, and should be interpreted as a meaning that allows various modifications to achieve a specific and smooth purpose for various washing functions of the frame (F).

Narrower than the cross-sectional lower plate 31 of the intermediate plate 33 is to prevent separation of the combined cleaning member (W).

In addition, the upper plate 35 above the middle plate 33 preferably has a larger cross-sectional area than the middle plate.

As can be seen in FIG. 3, this is particularly intended to cover the gripping portion 39A of the clamp 39 introduced for use with a common commercial scrubber.

In addition, in consideration of the frame F being rotated, it is preferable that the frame has a symmetrical shape so as not to apply an eccentric load to the shaft 21 and the motor 20.

To this end, the illustrated frame F has a circular planar shape of the upper and lower plates 35 and 31, and the intermediate plate 33 has an elliptical shape.

In addition, it is preferable that the intermediate plate 33 is elliptical and smaller in area than the lower plate 31.

This prevents the clamp 39 or its gripping portion 39A for introducing a commercial scrubber from protruding from the upper and side surfaces thereof so as not to injure the user or damage the object to be cleaned such as tableware.

The cleaning member fixed to the intermediate plate 33 is to prevent the situation that the idle separately without rotating with the frame (F) rotated by the rotational force of the motor,

If necessary, the cross-sectional shape of the intermediate plate may be such that any of these functions can be achieved equally (more preferably, to provide symmetry, preferably rotational symmetry with respect to the shaft, which is the axis of rotation). It may be non-circular in shape.

In addition, while the intermediate plate 33 is preferably smaller than the upper plate 35 in order to achieve the function,

In addition, the upper plate is possible in order for the pressurized carbon portion 39B of the clamp 39 having an elliptical shape to fit into the shape of the intermediate plate 33 can be easily introduced into the intermediate plate 33 beyond the upper plate 35. Small one is preferable,

The outer diameter of the upper plate 35 is equal to or slightly larger than the length of the elliptical long axis of the intermediate plate 33 in order to realize the ease of coupling of the clamp and the prevention of the protrusion of the grip portion (the clamp itself is the upper plate when viewed in plan view). It is preferable that the top plate is larger than the middle plate so that it does not protrude to the outside).

Accordingly, the cross-sectional area (ie, outer diameter) of the upper plate is preferably smaller than the cross-sectional area (ie, outer diameter) of the lower plate.

The grip portion 39A of the clamp 39 is located at the shortened portion of the elliptical intermediate plate 33,

In this case, it is preferable to provide a method for preventing the eccentric force from being applied to the shaft 21 due to the grip portion 39A of the clamp 39 during rotation.

For example, this is a projection 39a (see FIG. 3 right top plan view, FIG. 3 right top plan view) provided in a symmetrical form opposite to the grip portion 39A of the clamp 39, which corresponds to an exploded perspective view of the left side and another modification. May be).

In addition, any frame structure may be variously selected and applied in a manner of minimizing a problem that may occur due to a unique shape while achieving the above-described function with respect to the structure of the frame.

In the automatic dishwashing apparatus (A) according to the present invention, the custom-made washing member (W) of the washing members has a washing unit (W1) and the mounting band portion (W2) of the upper portion of the washing unit.

The washing unit (W1) is embedded with a sponge (W1a) surrounded by a rough coating to improve cleaning power,

The mounting band portion W2 accommodates the lower plate 31 of the frame F in a pocket shape.

Specific materials and sizes may be variously selected depending on the type of the object to be cleaned.

The mounting band part corresponds to a kind of 'clamping means' for fixing the cleaning member to the middle plate of the frame.

In particular, the intermediate plate 33 of the frame (F) has a recessed middle portion 33B, the elastic band (W2a) of the upper portion of the mounting band portion (W2) of the cleaning member (W) is introduced into the middle plate 33B Any rotation of the cleaning member (W) during rotation for cleaning was to be prevented.

In the drawing, the plate-shaped portion 33C and the plate-shaped portion 33A are formed at the upper and lower portions of the middle plate 33B, respectively.

If necessary, the plate portion may be omitted and may have a structure in which the upper plate is directly connected to the upper portion of the plate portion.

In addition, in the modification shown in the front sectional view in the lower right part of FIG. 1, a plurality of wedges 33a formed on the outer circumferential surface of the lower plate 33A are formed, so that the fabric forming the mounting band portion W2 of the cleaning member W is formed. Hanging to assist in the prevention of separation of the cleaning member.

Elastic band (W2a) of the cleaning member may be a separate rubber band, or may mean the elasticity of the fabric itself forming the mounting band portion (W2), functionally means the narrowest inlet of the upper end of the mounting band portion do.

Next, as shown in Figure 3, a commercial washing member (Wg), such as various scrubber towels generally available on the market can be fixed to the intermediate plate 33 of the frame (F) through the clamping means. .

In a state where all or part of the edge of the commercial cleaning member (Wg) is in contact with the intermediate plate (33) of the frame (F)

Press both grip portions 39A of the clamp 39, which is a kind of clamping means, to widen the pressurized carbon portion 39B as much as possible.

Through the top plate 35 of the frame

When the grip portion 39A is placed, the pressurized carbon portion 39B presses the edge of the commercial cleaning member Wg, thereby fixing the cleaning member.

In the middle of the pressurizing portion 39B of the clamp 39 has a trimming portion 39C, when the wedge 33a is provided on the lower portion 33A of the frame intermediate plate 33 as shown in the lower right variant of FIG. And the pressurized carbon part of the clamp do not contact,

In addition, the trimming part 39C can be fixed by exposing the edge of the commercial cleaning member Wg.

Next, various cleaning members W are illustrated in FIG. 4. First, in [A], there is a top-shaped cleaning member Wa suitable for cleaning a portion such as a corner of a cleaning object P1 such as a pan. Suitably, the lower plate 31A of the frame F also has a top shape (the bottom plate may have a flat plate shape and only the cleaning member may have a top shape).

[B] shows a cleaning member Wb provided in the rod-shaped frame Fb, which is suitable for cleaning the cleaning object P2 in the form of a bottle such as a baby bottle.

The cleaning member Wc shown in [C] is provided in the rod-shaped frame Fb and is suitable for wiping a narrow cleaning object P3 such as a nipple.

In Fig. 4 [B] and [C], it is preferable to have a fastening part for connecting to the drive unit shaft at the top of the rod-shaped frame Fb,

The rod-shaped frame Fb is omitted and may be used in a manner in which the shaft 21 is directly fastened to the hexagonal groove fastening portion of the frame as shown in FIG. 1.

In addition, Figure 5 shows a washing member of various forms,

First, [A-1] on the left is a soft and soft cleaning member made of so-called sponge or microfiber, and [A-2] is a cleaning member having a medium rough (or rough) hardness and relatively evenly distributed abrasive particles. It is a good model to use when cleaning high-quality tableware or weak materials. [A-3] is a strong (or rough) and hard material. Coarse and strong abrasive particles are spread evenly on synthetic yarn, so it has excellent cleaning power. Even if you use it, it is a model that can maintain the rough texture as it is, and [A-4] is an iron scrubber made of stainless steel, and it is effective for removing rust, sticking, and food waste that are not easily removed.

Next, [B-1] on the right side is provided with a brush, which is suitable for washing shoes, etc., and [B-2] corresponds to a washing member product including a collection of cleaning pieces such as fabrics, natural or artificial leather.

On the other hand, the present invention is provided with an uninterruptible power supply means associated with the battery to ensure the time for emergency repair, etc. can be used by the automatic dishwashing device for a certain time even if the commercial AC power is cut off due to power failure, etc. It can be called a kind of battery charging circuit.

The uninterruptible power supply means the charging circuit for connecting the external power and the battery as a core,

As shown in FIG. 6, when the commercial AC power is input, the charging circuit 143 converts the commercial AC power into driving power and supplies the motor to the motor.
