Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a cleaning device for a circulating bath kettle, and in particular, can clean not only the circulation pipe of the bath kettle, but also the scales deposited in the water chamber. Cleaning device for a simple circulating bath.

[Prior Art] As shown in Fig. 10, a circulating bath kettle used in a general household connects a bathtub (a) and a bathtub (b) with a circulation pipe (c), and a lower opening of the bathtub. (Suction port) (d) The water flowing into the bath kettle is heated by the burner (e), and the natural circulation force of the hot water is passed through the circulation pipe upper part and the bathtub upper opening (discharge port) (f). It has a structure that returns it to the bathtub. Also, the bath kettle has an inner torso and an outer torso.
And a water chamber (i) is formed between the inner body (g) and the outer body (h). Further, as shown in FIG. 11, the water chamber (i) and the circulation pipe (c) are communicated with each other by a thin pipe (n) branched from the circulation pipe.

Therefore, the circulating water flows through the thin pipe (nu) to the water chamber (ri).
It is configured to circulate inside. This water room
Is formed to enhance the thermal efficiency and to protect the bath pot (b) from heat.

By the way, as shown in the figure, the circulation pipe is intricately curved, and the narrowed water chamber (re) is formed inside the bath kettle as described above. It adheres and deposits on the inner walls of the pipe (C) and the water chamber (R). Especially in the water chamber, water is introduced and discharged only through the thin tube (nu), and the width itself is also narrow, so it is difficult to circulate the water sufficiently and it is easy for extra scale to accumulate. Had a problem. It is unsanitary to continue to use the bath in such a state, and in a remarkable case, sludge-like scales are discharged from the opening on the bath side, resulting in a very unpleasant result. Also, it goes without saying that the thermal efficiency is also negative.

Therefore, various methods have been hitherto tried for removing the scales deposited on the circulation pipe of the bath and the water chamber. The simplest method is to connect one end of a hose to the tap of the water supply and squeeze the other end to inject pressurized water through the upper and lower openings of the bathtub. However, it is not very effective because it can reach the pressurized water.

In addition, there is a circulating water circulation cleaning method by so-called thermal convection in which a commercially available detergent is administered to hot water in a bath and the kettle is ignited and heated. This is effective for cleaning the circulation pipe to some extent, but the water cannot be sufficiently cleaned because it is difficult for the circulating water to enter the narrowed narrow tube and the water chamber. In addition, since the detergent is poured into the bathtub while the hot water at a considerable water level (at least until the upper opening of the bathtub is completely hidden) is poured, a large amount of detergent is required to secure an effective concentration.

Furthermore, recently, a disposable instrument for connecting a bellows-shaped container to a lower opening of a bath and pumping a foaming agent into a circulation pipe is commercially available. In this method, the molten metal adhered and accumulated by the bubbles generated by the foaming agent is used as a peeling melt. However, in this case, most of the bubbles are generated near the inlet of the circulation pipe, and the generated bubbles are immediately combined to form a large air mass. However, there is a problem in that a sufficient cleaning effect cannot be expected because the wastewater cannot be reached and is discharged as it is through the circulation pipe to the outside of the kettle.

[Problems to be Solved by the Invention] The present invention can easily eliminate the thin pipes of the circulating bath kettle and the scales accumulated in the water chamber, which could not be sufficiently washed by the above-mentioned various conventional methods, and can be used for various purposes. An object of the present invention is to provide a cleaning device for a circulation type bath kettle that has a simple structure and can be easily used.

[Means for Solving the Problems] In order to achieve the above object, a circulating bath heater cleaning device according to the present invention is inserted into a circulation pipe of a circulating bath heater from a lower opening of a bath at one end of an air supply pipe. A porous bubble generating member, a pump means connected to the other end of the air supply pipe, and a fixing for inserting and fixing the air supply pipe in the lower opening of the bathtub in the middle of the air supply pipe. The means is attached, and an expandable and contractible bellows portion is provided in the middle of the air supply pipe between the bubble generating member and the fixing means, whereby the length of the air supply pipe between the bubble generating member and the fixing means is increased. In the cleaning device for a circulating bath with adjustable height, the bubble generating member comprises:
It is characterized in that it is arranged at a position reaching an inlet of a thin tube which communicates the circulation pipe with the water chamber of the circulation type bath.

Further, another circulating bath heater cleaning device according to the present invention is
A porous bubble generating member inserted into the circulation pipe of the circulating bath from the lower opening of the bath is connected to one end of the air supply pipe, and a pump means is connected to the other end of the air supply pipe to connect the air supply pipe to the air supply pipe. A water injection port is provided between the pump means and a fixing means for inserting and fixing the air supply pipe in the lower opening of the bathtub in the middle of the air supply pipe, and the bubble generating member and the fixing means. The expandable and contractible bellows part is provided in the middle of the air supply pipe between the two, thereby making it possible to adjust the length of the air supply pipe between the bubble generating member and the fixing means, and the bubble generating member and the circulation pipe. An air supply means arranged at a position reaching an inlet of a thin tube communicating with a water chamber of the circulating bath kettle, and one end of a substantially L-shaped pipe member for connecting with an upper opening of the bath. Attach the fixing means and connect the cup member to the other end Characterized in the that was configured so that the air discharge means.

The bath side of the air supply means and the bath side of the air discharge means may be connected and connected by a connecting pipe member to circulate the water filled in the circulating bath via the water inlet.

[Operation] When the circulating bath heater cleaning device according to the present invention is used, air is pumped from the pump means to the air supply pipe, and when the air passes through the bubble generating member connected to the tip of the air supply pipe. As a result, a large number of minute bubbles rise up in the circulation pipe of the bath and the water chamber and are discharged from the upper opening of the bath. In the meantime, the scales deposited on the circulation pipe of the bath kettle, the water chamber, etc. are separated and melted.

An expandable and contractible bellows portion is provided in the middle of the air supply pipe between the bubble generating member and the fixing means, so that the length of the air supply pipe between the bubble generating member and the fixing means can be adjusted. Therefore, even when the bubble generating member is used in various bathtubs having different distances from the lower opening of the bathtub to the thin tube, the bubble generating member can be arranged at a position reaching the inlet of the thin tube.

The air supply means is connected to the upper opening of the bathtub, and the air supply means is inserted and fixed in the lower opening of the bathtub. The air supply means is provided with a water injection port to supply water into the bathtub. In the case of being configured so as to be able to perform cleaning, only the water with which the bath pot is filled can be used for cleaning.

Further, when the air discharge means and the air supply means are connected to each other on the bathtub side by using a connecting pipe member, the wash water filled in the bathtub can be circulated.

[Embodiment] An embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a cleaning device 2 for a circulating bath kettle according to the present invention.
A first embodiment (hereinafter simply referred to as "cleaning instrument") is shown.

The cleaning instrument 2 has an air supply pipe 4 made of vinyl chloride or the like with an air bubble generating member 6 attached to one end thereof, and a hose 8 connected to the other end thereof. Furthermore, the hose 8
Pump means 10 is attached to the tip of the. In addition, the air pipe 4
By extending itself, the pump means 10 may be directly connected without the hose 8. A plug 12, which is a fixing means for fixing the cleaning instrument to the lower opening of the bathtub, is inserted in the middle of the air supply pipe 4 as described later.

The bubble generating member 6 is formed of a porous material such as urethane foam. Further, although a manual pump is illustrated as the pump means 10 in the figure, a pump driven by an electric motor or an electromagnetic type may be adopted.

FIG. 2 is a simplified cross-sectional view showing the usage state of the cleaning instrument 2 according to this embodiment, and FIG. 3 is a simplified cross-sectional view taken along the line II-II.

The cleaning instrument 2 is inserted into the lower portion 22 of the circulation pipe 20 of the bathtub 18 from the lower opening 16 of the bath 14 filled with water as shown in the figure, with the bubble generating member 6 at the head, and fixed by the plug 12. To be done. At this time, the bubble generating member 6 is positioned so as to block the inlet of the thin tube 26 that connects the water chamber 24 and the lower portion 22 of the circulation pipe (FIG. 3). That is, the length 1 (FIG. 1) of the air supply pipe sandwiched between the bubble generating member 6 and the plug 12 is configured so that the bubble generating member 6 is sufficiently close to the inlet of the thin tube 26. It should be noted that it is convenient to make the length of l adjustable so that it can be used in various bathtubs having different distances from the lower opening 16 of the bathtub to the thin tube 26. For the adjustment, a bellows portion 28 is provided in the middle of the air supply pipe 4 between the bubble generating member 6 and the plug 12, and the length of the air supply pipe itself can be varied by the expansion and contraction, or the position of the plug 12 can be changed back and forth. This can be realized by arranging the length 1 to be variable by shifting the length.

In the above-mentioned manner, the cleaning device 2 is attached to the bathtub 14 and the bath kettle 18.
When the pump 10 is operated and air is sent to the tip of the air supply pipe after being attached to the air conditioner, a large number of fine bubbles are generated from the bubble generating member 6. A part of the bubbles rises in the vertical portion 30 of the circulation pipe, passes through the upper portion 32 of the circulation pipe, and is discharged from the upper opening 34 of the bath. In the meantime, the bubbles stimulate the scale deposited on the inner wall of the circulation pipe, causing it to peel off and melt. On the other hand, the air bubbles generated in the vicinity of the inlet of the thin tube 26 enter the water chamber 24 formed between the inner shell 38 and the outer shell 40 of the bathtub 18 through the thin tube. In this way, bubbles that enter from below the water chamber 24
It goes up inside, reaches the upper part 32 of the circulation pipe through another thin tube 42 connected to the upper part of the water chamber, and is discharged from the upper opening 34 of the bath as it is. In the meantime, the scales adhered to the inside of the thin tubes 26 and 42 and the wall surface of the water chamber 24 are peeled off and melted. At this time, if the gas burner 43 of the bathtub is ignited for an appropriate time to heat the water in the bathtub, the melting effect can be further enhanced.

As described above, air is continuously sent for a predetermined time to sufficiently stimulate the scales in the circulation pipe 20 and the water chamber 24, and then the water in the bathtub is drained. And as a finishing touch, the top and bottom openings of the bathtub
From the 34,16, pressurized water is injected with a hose and washed to discharge the remaining scale of the scale.

As described above, in the present embodiment, since bubbles are generated near the inlet of the thin tube 26, it is possible to send bubbles to the thin tubes 26, 42 and the water chamber 24 which could not be sufficiently washed by the conventional washing method. , Can effectively peel and melt the scales adhered to them.

FIG. 4 shows a second embodiment of the cleaning instrument according to the present invention. The cleaning implement 44 according to the present embodiment includes an air discharging means 46 attached to the upper opening 34 of the bath and a lower opening of the bath.
The air supply means 48 mounted on the 16 is provided.

The air discharge means 46 has a substantially L shape bent at a substantially right angle in the middle.
A stopper 52 made of rubber or the like, which is a fixing means, is inserted through one end of the character-shaped pipe member 50, and a shibuki retainer 54, which is a cup member, is detachably connected to the other end. The Shibukidome 54
The opening of the cup is covered with a sponge 55. The air discharging means 46 is configured such that the stopper 52 is provided in the upper opening of the bath.
It is inserted into 34 and is fixed so that the Shibuki residue 54 is held up. At this time, the air discharging means 46 needs to be arranged so that the connecting portion 56 of the shibuki terminal 54 is located at least higher than the upper portion 32 of the circulation pipe. Although the plug 52 inserted into the upper opening 34 is illustrated as the fixing means of the air discharging means 46, a cap member fitted to the edge of the upper opening 34 may be adopted (not shown). .

The air supply means 48 has the same basic structure as that of the cleaning instrument 2 according to the first embodiment. That is, the bubble generating member 6 is attached to the tip of the air supply pipe 4, and the other end is connected to the pump means 10 via the hose 8. Also,
A plug 12, which is a fixing means for fixing to the lower opening 16 of the bathtub, is inserted in the middle of the air supply pipe 4. However, in the air supply means 48 according to this embodiment, a water injection port 60 for supplying water into the bathtub 18 is provided at an appropriate position between the air supply pipe 4 and the pump means 10. Cleaning device 2 according to one embodiment
Is different from. In the figure, the water injection port 60 is provided immediately in front of the pump means 10, but due to the action of the valves 62 and 64, water does not enter the pump even when water is being injected.

FIG. 5 is a simplified sectional view similar to FIG. 3, showing the usage state of this embodiment.

First, the plug 52 of the air discharging means 46 is inserted into the upper opening 34 of the tub 14 from which water has been drained, and the air supplying means 48 is inserted into the lower opening 16 of the tub. At this time, the bubble generating member 6 is a thin tube.
It goes without saying that they are positioned so as to block the entrances of 26.

If a commercially available cleaning agent is previously administered to the circulation pipe 20 before the air supply means 48 is inserted, more effective cleaning can be performed.

Next, water is supplied from the water injection port 60, and the circulation pipe 20 and the water chamber 24 of the bathtub are filled with water through the pores of the bubble generating member 6 attached to the tip of the air supply pipe 4.

After that, the pump 10 is operated to feed air to generate bubbles. As described above, the bubbles are the circulation pipe 20 and the water chamber.
In addition to stimulating the scale in the inside of 24, the cleaning agent can more strongly wash the scale. Further, at this time, by igniting the gas burner 43 of the bath kettle and heating it for a predetermined time, the melting of the scale can be promoted.

A large amount of bubbles are generated by using the cleaning agent, but this can be solved by adding an appropriate defoaming agent. Still, a small amount of bubbles may still be generated, but since this is also captured by the sponge 55 that closes the opening of the Shibuki residue 54, it does not overflow to the outside.

By the way, the air discharge means 46 includes the circulation pipe 20 and the water chamber.
In addition to the role of the exhaust port for discharging the bubbles that have passed through 24 to the outside of the bath kettle 18 and the role of the Shibuki residue, the connection portion 56 of the Shibuki residue is higher than the upper portion 32 of the circulation pipe as described above. Since it is arranged so as to be located, it also plays a role of a stopper for preventing the water filled in the bath pan 18 from flowing out.

In the case of the present embodiment, unlike the first embodiment, the water filled in the bathtub 14 is not used as the washing water for the bath kettle 18, but the bath kettle 18 closed by the air discharge means 46 and the air supply means 48. Since only the water that fills the inside is used as washing water, there is an advantage that a sufficient washing effect can be achieved by administering a small amount of detergent.

In the case of this embodiment as well, as in the first embodiment, as a finishing of the cleaning, the adhered residue is discharged by injecting pressurized water from the upper and lower openings 34, 16 of the bath 14.

FIG. 6 shows a third embodiment of the cleaning apparatus according to the present invention. The cleaning device 66 according to the present embodiment is provided with the air discharge means 46 and the lower opening 16 mounted in the upper opening 34 of the bath.
The air supply means (48) attached to is connected to and connected to the bathtub side by a connecting pipe material. As this connecting pipe material, a combination of two long and short pipes is used. That is, the air supply pipe 4 of the air supply means 48 is inserted into a short pipe 68 having a diameter larger than this, and the plug 70 previously penetrated into the air supply pipe 4 is inserted into the short pipe 68.
By fitting the right end 72 of the air pipe 4 to the short pipe 68
Hold hollow inside. As a result, as shown in FIG. 7, a gap 74 for circulating water is formed between the air supply pipe 4 and the short pipe 68. Next, one end 78 of the long pipe 76 is vertically connected to the short pipe 68, and
The other end 80 of 76 is communicatively connected to the air discharge means 46. The left end 82 of the short pipe 68 is penetrated by a stopper 84 made of rubber or the like as a fixing means. By inserting the stopper 84 into the lower opening 16 of the bath, the bubble generating member 6 of the air supplying means 6 Is inserted and fixed in the bath kettle 18.

The configurations of the air discharge means 46 and the air supply means 48 are the same as those of the second embodiment.

 FIG. 8 shows the usage of this embodiment.

As shown in the drawing, by attaching air discharge means 46 to the upper opening 34 of the drained bathtub 14 and air supply means 48 to the lower opening 16, the circulation pipe 20 and the water chamber 24 of the bath can be washed. A closed water circulation system is formed with the device 66. When using the cleaning agent, the cleaning agent and the defoaming material are administered in the circulation pipe 20 before the air supply means 48 is attached.
Next, water is supplied from the water injection port 60 to fill the bath kettle 18 and the cleaning device 66 with water, and air is sent by the pump 10.
The air becomes fine bubbles from the bubble generating member 6 attached to the tip of the air supply means 48, and becomes the circulation pipe 20 and the water chamber 24.
Combined with the effect of the cleaning agent that is released and administered inside, it peels off and melts the scale that has adhered to the inside of the bath. At this time, as in the case of the first and second embodiments, if the gas burner 43 is ignited to appropriately heat the water in the bath kettle, the cleaning effect is further enhanced. In the case of this embodiment, since the water circulation system is formed as described above, the wash water in the bath 18 is circulated by the force of the air (air bubbles) emitted and the natural circulation force of the heated water. Therefore, as compared with the case of the first and second embodiments, the scales in the circulation pipe 20 and the water chamber 24 can be cleaned more effectively.

Depending on the bathtub, the distance between the upper opening 34 and the lower opening 16 may be different, but this can be dealt with by making the middle of the long pipe 76 a bellows shape and making the length variable (see the figure). Is omitted). Alternatively, several types of long pipes 76 having different lengths may be prepared and a length suitable for the bathtub may be appropriately selected.

The three embodiments of the cleaning apparatus according to the present invention have been described above, and their mutual relationships will be described below.

That is, if the cleaning effects are arranged in descending order, the order of the third, second, and first embodiments will be obtained, but this is also a troublesome order. Therefore, when cleaning a bath kettle that has been used for many years, it is cleaned according to the third embodiment, which has the highest cleaning effect, and thoroughly removes dirt for many years. After that,
The cleanliness can be maintained by carrying out the cleaning periodically according to the second or first simple example as appropriate.

If this cleaning device is configured as shown in FIG. 9, it is possible to use one cleaning device as three types of embodiments without separately providing the above three types of cleaning devices. That is, the air discharge means is based on the third embodiment.
The 46 and the long pipe 76 and the long pipe 76 and the short pipe 68 are detachably configured by a screwing method or the like. And
After removing the long pipe 76 from the air discharge means 46 and the short pipe 68, the connection openings 90, 92 of the air discharge means 46 and the short pipe 68 can be closed by the caps 86, 88 and the like. As a result, when it is desired to use it as the third embodiment, it is used with the long pipe 76 attached, and when it is desired to use it as the second embodiment, the long pipe 76 is removed to close the connection openings 90 and 92, respectively. To use. Needless to say, if it is desired to use it as the first embodiment, the air discharging means 46 may simply be excluded from the example of the second embodiment.

[Effects of the Invention] As described above, the present invention is configured to generate bubbles near the inlet of the thin tube that connects the water chamber of the circulating bath kettle and the circulation pipe, and thus cannot be sufficiently washed in the past. It is possible to effectively clean the scales deposited and accumulated in the water chamber. Further, since the length of the air supply pipe between the bubble generating member and the fixing means can be adjusted by the expandable and contractible bellows portion, the bubble generating member is surely arranged at a position reaching the inlet of the thin tube. It can be used for various bathtubs having different distances from the lower opening of the bathtub to the narrow tube.

The air supply means is connected to the upper opening of the bathtub, and the air supply means is inserted and fixed in the lower opening of the bathtub. The air supply means is provided with a water injection port to supply water into the bathtub. Since it is configured so that it can be washed using only the water filled in the bath kettle, as a result, a sufficient washing effect can be obtained by using a small amount of detergent.

Furthermore, since the air discharge means and the air supply means are connected and connected on the bathtub side by using the connecting pipe material, the wash water filled in the bath can be circulated, and a stronger wash effect can be realized. it can.
