Description

  The present invention relates to a bath tub cleaning tool used when cleaning the inside of a household circulation bath tub, and a bath tub cleaning method for cleaning the bath tub using the bath tub cleaning tool.

  A bath tub is connected to the home tub. The hot water in the tub is sucked into the bath tub and heated in the bath tub, and the heated hot water is returned to the tub to increase the temperature of the hot water in the tub. The thing of the formula is known.

  This kind of circulating bath has two-hole type and one-hole type. The two-hole bath is provided with a suction port for sucking hot water in the bathtub and a discharge port for discharging heated hot water into the bathtub. In this apparatus, the suction port is provided below, the discharge port is provided above the suction port, and hot water is naturally convected in the bath using the physical property that heated hot water rises. On the other hand, in the one-hole type, the discharge port and the suction port are provided at the same position, and hot water is forced to circulate in the bath with a pump provided separately.

  In any system, since hot water in the bathtub is circulated in the bath, dirt such as hot water is attached to the bath. Therefore, unless the inside of the bath is regularly cleaned to remove the dirt, there is a problem that the thermal efficiency is lowered, and microorganisms grow to contaminate the hot water.

  In order to clean the two-hole bath, the granular cleaning agent is filled in a bellows-shaped simple container, and the container is pressed into the suction port with hot water in the bathtub, and the cleaning agent is fed. Such a product (for example, product name “Java”: registered trademark) is known.

  Since the suction port is not exposed in the 1-hole bath, the cleaning agent is dissolved in the entire hot water in the bathtub, and the hot water containing the cleaning agent is forced to circulate in the bath and is washed. However, in this method, the cleaning agent must be dissolved in a large amount of hot water, and the concentration of the cleaning agent cannot be increased. Therefore, it is difficult to exert a sufficient cleaning effect.

Therefore, with all the hot water in the bathtub drained, cover the water inlet and drain with a relatively small container, put hot water and cleaning agent into the container, operate the bath, and hot water in the container. There is known a bath tub cleaning tool in which the bath tub is cleaned by circulating the water and the cleaning agent in the bath tub (see, for example, Patent Document 1).
JP-A-8-159695 (FIG. 1)

  In the two-hole cleaning tool filled with the cleaning agent in the above simple container, the suction port for feeding the cleaning agent is provided near the bottom of the bathtub, so put your hands deeply into the bathtub filled with hot water In the unstable posture, the cleaning agent must be sent into the suction port several times. Therefore, workability is bad. In addition, the hot water in which the cleaning agent has dissolved returns to the bathtub from the discharge port, but diffuses directly into the hot water in the bathtub and does not circulate again from the suction port to the bath tub, so that the cleaning agent cannot be used effectively. .

  On the other hand, if the bath tub cleaning tool described in the above publication is used, high-concentration hot water with the cleaning agent dissolved therein can be circulated in the bath tub, and the cleaning agent can be used effectively, It must be closely attached to the wall of the bathtub so that the filled hot water does not leak.

  Moreover, hot water must be circulated while the bath tub is in operation, but if the capacity of the container is small, the hot water temperature immediately rises and the circulation stops in a short time. In order to continue circulation for a certain period of time, it is necessary to increase the capacity of the cleaning tool so that it can be filled with a large amount of hot water. However, if the capacity is increased in this way, the cleaning tool can easily fall off due to its own weight. And the amount of leakage from the wall of the bathtub also increases.

  Particularly, when used for cleaning a two-hole bath, the temperature of the hot water discharged from the discharge port is high, and it is dangerous if the hot water is spilled and applied to the operator.

  Then, this invention makes it a subject to provide the bath kettle washing | cleaning tool which does not produce the above-mentioned trouble, and the bath kettle washing | cleaning method using the bath kettle washing | cleaning tool in view of said problem.

  In order to solve the above problems, a bath tub cleaning tool according to the present invention includes a suction port that sucks hot water in a bathtub and guides it to the bath tub, and a discharge port that discharges hot water heated in the bath tub to the bathtub. The bath is set in the bathtub so as to cover the suction port and the discharge port, and the cleaning water in which the cleaning agent is dissolved is held at least in the opening portion of the suction port so that the cleaning water is sucked into the bath. The pot cleaning tool is characterized in that a cleaning agent inlet formed on the upper surface is opened on the water surface in a state of being set on the wall surface of a bathtub in which hot water is stretched so that the suction port and the discharge port are submerged.

  In the above configuration, since the bath is submerged except for the cleaning agent inlet formed in the upper part of the bath tub cleaning tool, even if the volume of the bath tub cleaning tool is increased to increase the amount of cleaning water stored inside, There is no problem that the washing pot cleaning tool comes off from the bathtub wall due to the weight of the washing water, or the washing water leaks out and the interior becomes empty.

  By the way, it has a frame-like base part provided with a plurality of suction cups adsorbed to the inner wall of the bathtub, and a skirt part whose tip abuts along the inner wall of the bathtub in a state where the base part is adsorbed to the inner wall of the bathtub. If it is provided, even if the wall surface of the bathtub is curved, the skirt portion is appropriately curved and abuts along the wall surface of the bathtub, so that no gap is generated between the wall surface and the bathtub.

  And if hot water is added to the inside from the detergent inlet opening on the water surface, an outflow structure that allows outflow of hot water from the inside to the bathtub side through the submerged portion may be provided.

  In this case, the skirt portion may function as the outflow structure.

  In addition, if the said suction cup is a long suction cup formed so that the longitudinal direction may follow the frame part of a base | substrate part, the raising of a base | substrate part is prevented. The long suction cup preferably has a higher suction cup height than the suction area where the contact angle between the suction cup inclined portion and the suction surface of the suction cup is 35 to 45 °. The surface of the bathtub to which the suction cup adsorbs is often gently curved, and if the height of the suction cup is small, it is necessary to bend the frame part according to the bathtub surface, but it is flexible to various curved surfaces Although it is difficult to cope with the shape of the frame portion without any gap, the curved surface can be easily accommodated when the height of the suction cup is 5 to 10 mm. In the case of a normal circular suction cup, if the contact angle between the suction cup inclined part and the suction surface is 30 ° or more, the contact part of the suction cup and the suction face will be swollen at the time of suction, but the suction will be uncertain. Even if the suction cup has a higher height than the suction area with a contact angle of 35 to 45 °, the contact portion will not be swung at the time of suction and the suction will not be uncertain.

  It is desirable that the suction cup and the skirt portion are connected and formed integrally, and the skirt portion is separated from the inner wall of the bathtub so that the suction of the suction cup to the inner wall of the bathtub can be released.

  If the part where the washing water is stored is configured to be foldable, the storage space can be reduced.

  In addition, even if the capacity of the bath tub cleaning tool is relatively small by providing replacement means that allows the hot water inside the bath tub to flow out to the tub side and replace it with the low temperature hot water in the tub. The internal temperature rise rate can be reduced, and as a result, the duration for circulating hot water in the bath can be lengthened.

  By the way, if the skirt portion is too thick, the suction cup may be peeled off by the elastic force of the skirt portion. Therefore, it is desirable to make the elastic force of the skirt portion small so that the sucker is not easily detached by making the skirt portion thinner than the suction cup.

  To pull the suction cup away from the inner surface of the bathtub in water, a much larger force is required than in the case of pulling it away in the air. In particular, a very large force is required to pull away from the inner surface of the bathtub in the vertical direction. However, if the center position of the suction cup located at the top of the suction cups provided on the left and right sides is set to be lower than the middle position in the vertical direction of the bath pot cleaning tool, the bathtub pot cleaning device Even if it is flipped perpendicularly to the inner surface of the special search, the upper part is first separated from the inner surface of the bathtub, and then the upper end of the suction cup located at the uppermost part of the left and right is pulled away from the wall surface. After that, the suction cup can be pulled away from the wall surface with a small force.

  In addition, on the surface opposite to the surface on which the suction cup is provided, a handle member having rigidity extending in the vertical direction is provided so as to be foldable, and a finger hook portion for hooking a finger on the handle member is formed by being displaced upward. Thus, the bath tub cleaning tool can be adsorbed on the inner surface of the bathtub without putting much hand into the hot water in the bathtub.

  By the way, the cleaning solution in which the cleaning agent is dissolved is heated in the bath, but the amount of the cleaning solution is very small relative to the hot water in the bathtub. For this reason, when the cleaning liquid is heated in the bath, the temperature of the cleaning liquid rises rapidly. If a rod thermometer is used to measure the temperature of the cleaning liquid, the temperature measurement is troublesome, and the cleaning liquid may become cloudy due to a large number of minute bubbles, making it difficult to identify the thermometer index.

  In such a case, at least a part of the wall that separates the hot water and the cleaning liquid in the bathtub is made transparent, and a temperature-sensitive display member whose display changes depending on the temperature of the cleaning liquid is attached to the transparent part from the cleaning liquid side. It is desirable to configure so that the temperature of the cleaning liquid can be visually confirmed from the hot water side.

  In particular, in the case of a two-hole bath, there is often no mechanism for automatically stopping the burner on the bath side even when the temperature of the cleaning liquid rises above the assumed temperature. In such a case, an opening is formed in a part of the wall portion that isolates the hot water in the bathtub from the cleaning liquid, and the temperature of the cleaning liquid is set to a predetermined temperature by a temperature-sensitive member that changes its shape when the temperature is reached. Until it reaches, the opening is closed, and when the temperature reaches a predetermined temperature, the opening is opened, and a cleaning liquid temperature rise prevention mechanism for allowing the hot cleaning liquid to escape to the bathtub side may be provided.

  With this configuration, for example, even when an operator leaves the bathroom while cleaning the bath, when the temperature of the cleaning liquid is heated to a predetermined temperature or more, the opening is opened, and one of the high temperature cleaning liquid The part is replaced with low-temperature hot water in the bathroom, and the temperature rise of the cleaning liquid is suppressed.

  In order to solve the above-mentioned problems, a bath tub cleaning method according to the present invention is a method for cleaning a bath tub using the bath tub cleaning tool according to any one of claims 1 to 11, wherein the discharge port has a discharge port. An attachment step in which the bath tub cleaning tool is attached to the inner wall of the bathtub so that the upper part opens on the water surface and covers the discharge port and the suction port, with the hot water in the bathtub until the water level is submerged. It is characterized by comprising a cleaning step of supplying a cleaning agent into the interior and operating the bath tub to circulate the hot water and the cleaning agent inside the bath tub to wash the bath tub.

  According to this method, it is possible to wash the bath with hot water having a high concentration of the detergent even in a state where hot water is stretched in the bathtub.

  If a bath tub cleaning tool having an outflow structure is used, the bath tub can be further washed with clean hot water after the cleaning step, and the cleaning liquid can be discharged from the bath tub.

  By the way, it is desirable that a foaming agent that foams when put into water is put into a bath tub cleaning tool, and the hot water or cleaning agent in the bath tub cleaning tool is stirred by bubbles generated by the foaming agent.

  When the hot water or the cleaning agent in the bath tub cleaning tool is thus agitated by foaming, the cleaning agent can easily flow into the bath side, and the cleaning effect can be improved. Moreover, the temperature difference in the vertical direction in the bath tub cleaning tool can be reduced, and in particular, the vicinity of the water surface can be prevented from becoming abnormally hot. The foaming agent may be added at the same time as the cleaning agent. However, foaming is performed when the cleaning agent is first added and dissolved, and when the bath tub is operated to circulate the cleaning agent in the cleaning tool inside the bath tub. An agent may be added. Even if the foaming agent is added at any timing, the concentration and temperature of the cleaning agent in the cleaning tool can be made more effective and uniform by the generated bubbles.

  As is apparent from the above description, the bath tub cleaning tool according to the present invention is used in a state where hot water is stretched in the bathtub. Since the cleaning tool is difficult to drop off from the wall surface of the bathtub and there is little leakage of the hot water inside, there is no need for the operator to continue to hold the bath cleaning tool by hand during the cleaning operation.

  Referring to FIG. 1, reference numeral 1 denotes a bath tub cleaning tool (hereinafter simply referred to as a cleaning tool) according to the present invention. The cleaning tool 1 is attached to the wall surface of the bathtub BT. However, in this embodiment, the bathtub BT has a suction port for sucking hot water in the bathtub BT into an external bath pot (not shown) and a discharge port for discharging hot water heated in the bath pot into the bathtub BT. The suction part C is provided, and when the cleaning tool 1 is attached to the wall surface of the bathtub BT, the suction part C is attached so as to cover the cleaning tool 1.

  Note that when the cleaning tool 1 is attached, hot water is stretched in the bathtub BT, and the water surface W is located above the suction portion C, that is, the suction portion is completely submerged. . Then, when the cleaning tool 1 is attached to the wall surface of the bathtub BT in this manner, hot water enters the cleaning tool 1 and the heights of the water surfaces W inside and outside the cleaning tool 1 become the same height.

  The upper surface of the cleaning tool 1 is open, and the cleaning agent can be poured into the cleaning tool 1 from the opening. This cleaning agent may be solid, powder, liquid, or the like, but in the present embodiment, a tablet-like material is used as shown in FIG. When the cleaning agent T is put into the cleaning tool 1 in this way, the cleaning agent T settles down to the bottom of the cleaning tool 1. Then, the cleaning agent T is located in the vicinity of the discharge part C. The cleaning agent T contains a foaming agent such as sodium carbonate, and generates foam when it is put into water. Since the bubbles rise in the cleaning tool 1, the cleaning liquid generated in the cleaning tool 1 can be continuously stirred for a long time.

  When the bath tub is operated in this state, a pump (not shown) is operated to suck the hot water in the cleaning tool 1 from the discharge part C to the bath tub. At that time, since the cleaning agent T is dissolved in hot water, the dissolved cleaning agent is sucked together with the hot water into the bath with a pump. When the cleaning agent reaches the bath, the hot water containing the cleaning agent is heated, so that the cleaning agent is activated, and dirt such as scale attached to the inside of the bath is peeled off or dissolved.

  Then, the hot and cold water that has passed through the bath tub is discharged into the cleaning tool 1 from the suction part C. The hot water discharged in this way contains a high-concentration cleaning agent, is isolated from the inside of the bathtub BT by the cleaning tool 1, and is again sucked from the discharge part C to the bath.

  By the way, in the so-called 1-hole type bath tub provided with such a suction / discharge section C, the temperature of the hot water to be sucked is monitored by a sensor, and when the temperature reaches a set temperature, the operation of the pump and the bath tub is automatically performed. Is configured to stop automatically. Therefore, if the capacity in the cleaning tool 1 is small and the hot water temperature in the cleaning tool 1 rises in a short time, the pump and the bath tub stop before the bath is sufficiently cleaned, and the cleaning operation cannot be continued.

  In order to eliminate such a problem, the capacity of the cleaning tool 1 must be increased to some extent. However, if the capacity is increased more than necessary, the concentration of the cleaning agent decreases, so that a large amount of cleaning agent needs to be introduced. Therefore, in the present embodiment, in view of the heating capability of a general household bath tub, 0.5 to 20 liters of hot water is stored in the cleaning tool 1. This capacity is preferably set to 1 to 10 liters, more preferably 1.5 to 5 liters.

  By the way, the cleaning tool 1 includes a frame-shaped base portion 2 and a partition wall portion 3 that is detachably attached to the base portion 2 as shown in FIG. The base portion 2 is integrally formed of a flexible resin, and suction cups 21 for attachment to the flat surface of the bathtub BT are formed at four locations. In addition, a seal portion 22 corresponding to a skirt portion slightly curved outward is formed integrally with the base portion 2 on the left and right sides and the bottom side of the base portion 2. Although the function of the seal portion 22 will be described later, the seal portion 22 constitutes an outflow structure.

  Holding parts 23 are formed on the inner sides of the left and right and bottom parts of the base part 2, and holding grooves 24 are formed on the outer side of the holding part 23 as shown in FIG. 4. The partition wall 3 is attached to the base body 2 by inserting the partition wall 3 into the holding groove 24.

  An engagement protrusion 25 is formed on the outer peripheral surface side of the holding portion 23, and when the partition wall 3 is inserted into the holding groove 24, the engagement protrusion 25 is engaged with the engagement window 31 formed in the partition wall 3. In addition, the partition wall portion 3 was prevented from inadvertently dropping off from the base body portion 2. Since the holding part 23 is formed of a flexible resin as described above, the partition part 3 can be easily detached from the base part 2.

  On the other hand, the partition wall 3 can be folded when removed from the base 2 as shown in FIG. 5. After the cleaning operation is completed, the partition 3 is detached from the base 2 and folded as shown in FIG. Can be reduced. In the present embodiment, the partition wall 3 is folded by folding the left and right side surfaces 32 inward and folding the bottom surface 33 into a mountain shape.

  By the way, as shown in FIG. 6, the above-described seal portion 22 is bent with the tip end outside when the base portion 2 is attached to the wall surface of the bathtub BT. Therefore, it will contact | abut to the wall surface of bathtub BT by own elastic force. If it will be in such a state, even if the hot water in the bathtub BT tries to flow out into the cleaning tool 1, it is blocked by the seal portion 22 and cannot flow in. Moreover, since the height of the water surface W in the bathtub BT and the water level in the cleaning tool 1 are the same height, there is no flow from the inside of the cleaning tool 1 toward the bathtub BT, so that the cleaning liquid in the cleaning tool 1 is removed. The sealed portion 22 prevents the dissolved hot water from leaking into the bathtub B.

  In addition, in this Embodiment, in order to attach the base | substrate part 2 to the wall surface of bathtub BT, the suction cup 21 was used. The suction cup 21 is adsorbed by pressure from the outside by making the inside vacuum. Therefore, when the suction cup 21 is used in water as in the present embodiment, the water pressure acts as an adsorption force, and a stronger adsorption force can be exhibited compared to the case where it is used in the air. Therefore, even if the cleaning tool 1 is not held by hand during the cleaning operation, it is strongly fixed to the wall surface of the bathtub BT.

  Now, when the pump and bath tub are continuously operated for a predetermined time as described above and the bath tub is sufficiently cleaned, the upper opening in the cleaning tool 1 is left with the pump and bath tub operating. Inject clean water from the area. Then, the water level in the cleaning tool 1 rises above the surrounding water surface W. Therefore, the pressure in the cleaning tool 1 becomes higher than the surrounding pressure, and the hot water in the cleaning tool 1 leaks out to the bathtub BT side through between the seal portion 22 and the wall surface of the bathtub BT.

  If clean water is poured into the cleaning tool 1, the temperature of the hot water in the cleaning tool 1 is lowered, so that the bath tub continues to operate. Since the hot water in the cleaning tool 1 is replaced with clean water, clean hot water is circulated and rinsed in the bath, so that no cleaning liquid remains in the bath. This completes the washing process of the bath tub, then removes the stopper of the drain of the bathtub to drain the hot water in the bathtub BT, and finally removes the cleaning tool 1 from the wall of the bathtub BT.

  By the way, in the said embodiment, although demonstrated by the 1-hole type thing with which the water inlet and discharge port were united, even if it applies this invention to a 2-hole type thing, there is no problem. However, in the case of the two-hole type, hot water is not forcedly circulated in the bath pot by a pump, but is circulated by natural convection. Moreover, the temperature of the hot water to be sucked in is not detected, so that hot hot water stays in the upper part of the cleaning tool 1 and there is a possibility that a sufficient amount of hot water cannot be circulated in the bath.

  Therefore, as shown in FIG. 7, a replacement window 34 functioning as replacement means is provided in a part of the partition wall 3. This replacement window 34 is formed so as to straddle the water surface W up and down, and a part of high-temperature hot water sucked from the water inlet OL and discharged from the discharge port IL passes through the replacement window 34 to the bathtub BT side. leak. Then, along with the outflow of the high temperature water, the low temperature hot water in the bathtub BT flows into the cleaning tool 1 through the replacement window 34, lowers the hot water temperature in the cleaning tool 1, and the temperature in the cleaning tool 1. Reduce inequality. Then, as in the case described above, after the cleaning is completed, clean water is injected from above and the cleaning liquid in the bath is discharged.

  By the way, in said embodiment, in order to attach the base | substrate part 2 to the wall surface of the bathtub BT, although the four circular suction cups 21 were used, while raising the adsorption | suction power further, the floating from the bathtub BT of the base part 2 was used. In order to prevent this, as shown in FIG. 8, a long suction cup 26 may be formed integrally with the base 2 instead of being circular. The long suction cups 26 are formed so that the longitudinal direction thereof is along the frame of the base portion 2. In the present embodiment, a total of three long suction cups 26 are formed. In addition, you may form the base | substrate part 2 in the U shape open | released upwards.

  By comprising in this way, since the whole base | substrate part 2 adsorb | sucks to the bathtub BT, the floating of the base | substrate part 2 from bathtub BT is prevented. A seal portion 22 was formed between the long suction cups 26. Since the seal portion 22 is formed continuously with the long suction cup 26, when the base portion 2 is removed from the bathtub BT while adsorbed to the bathtub BT, if the seal portion 22 is lifted, the long suction cup 26 is removed. It can be easily removed from the bathtub BT.

  By the way, when the thickness of the seal part 22 is thick, even if it is made to adsorb | suck to the bathtub BT with the long suction cup 26, there exists a possibility that the long suction cup 26 may remove | deviate with the elastic force of the seal part 22. FIG. Therefore, the thickness t1 of the seal portion 22 is made thinner than the thickness t2 of the long suction cup 26. Desirably, t1 is about 30% to 80% of t2.

  Moreover, although the form of folding the partition wall portion 3 was described with reference to FIG. 5, as shown in FIG. 9, the partition wall portion 3 may be folded while the partition wall portion 3 remains attached to the base body portion 2. . In the embodiment shown in FIG. 9, the volume of the partition wall portion 3 is reduced by folding the bottom surface 33 inward and folding the left and right side surfaces 32 into a mountain shape.

  Furthermore, it may be modified as shown in FIG. In the example shown in the figure, the skirt portion 22 is formed inside the long suction cup 26. In addition, a frame-shaped reinforcing plate 35 is provided at a substantially intermediate position in the vertical direction. Thereby, the rigidity in the assembled state can be increased. Since the reinforcing plate 35 can be flipped up like the bottom plate 33, there is no hindrance to folding.

  Moreover, it provided so that height L2 of the center position of the long suction cup 26 provided in right and left may be located below the intermediate position M of the whole height L1. By lowering the position of the long suction cup 26 in this manner, when the long suction cup 26 is pulled away from the bathtub BT, the upper end portion of the long suction cup 26 is pulled away from the bathtub BT together with the skirt portion 22, and the long suction cup 26 is easily pulled away from the bathtub BT. Can do. By the way, in the present embodiment, one long suction cup 26 is provided on each of the left and right sides, but a plurality of long suction cups may be provided on each of the left and right sides. May be set so that the center position is located below M.

  In the case shown in FIG. 10, three engagement claws 36 are further attached near the upper end. The engaging claw 36 can extend the height of the main body by engaging the foldable extension plate 4 with the engaging claw 36. In the present embodiment, the extension plate 4 is formed of a thin plastic plate. Thereby, an extension board will have moderate flexibility, and it can contact | adhere to a wall surface like a skirt part by slightly abutting and contacting with respect to the wall surface of bathtub BT.

  For example, as shown in FIG. 11, when the suction part C is disposed below and the water depth is deep, the extension plate 4 is placed in the posture shown on the left in FIG. It can be used with its length extended upward.

  In addition, as shown in FIG. 12, when the stool portion CH is formed on the inner wall of the bathtub BT and the sucking portion C is provided below the stool portion CH, the chemical solution is placed on the stool portion CH side. leak. Therefore, the extension plate 4 is reversed from the mounting state shown in FIG. 11 as shown on the right side of FIG. 10 and inserted from above to the position where it abuts against the reinforcing plate 35, and the upper half of the opening is closed with this extension plate 4. It is desirable to prevent the chemical liquid from flowing out to the stool portion CH side.

  Incidentally, a foldable handle portion 37 is provided in order to facilitate the suction and removal of the long suction cup 26. In addition, a finger hook portion 37a that can be gripped by placing a finger on the handle portion 37 is provided so as to be displaced upward. Thereby, when adsorb | sucking the elongate suction cup 26 to the bathtub BT, it becomes possible to press from diagonally upward, and to separate | separate from upper direction when removing. Note that the length of the handle portion 37 in the vertical direction preferably extends over substantially the entire length of the main body, but it is preferable that the length extends over at least 70%.

  Furthermore, in each of the above embodiments, the temperature display means may be provided in a portion located below the water surface W in a state of being attached to the bathtub BT, that is, a portion submerged in hot water. This temperature display means may be applied with a paint containing a temperature-sensitive dye, or a film containing a temperature-sensitive dye may be applied, and the color changes at a predetermined temperature so that the user can know the temperature of hot water. Thus, it is configured by displaying characters, symbols, and others.

  And it sets so that two temperature ranges, for example, 50-60 degreeC and 70-80 degreeC, may be displayed. In daily washing, the hot water in the bath can be decomposed and washed by heating the hot water to 50-60 ° C. In addition, dirt such as stubborn hot water attached to the bath for many years can be decomposed and washed by heating the hot water to 70 to 80 ° C. Therefore, the user needs to adjust the hot water temperature according to the purpose of cleaning, but if the temperature display means is provided, the user can easily know the hot water temperature.

  This temperature-sensitive temperature display will be described with reference to FIGS. In the configuration shown in FIG. 13, at least the wall portion 38 is formed of a transparent resin. And the temperature sensitive display member 5 was stuck on the inner surface of this wall part 38. FIG. The temperature-sensitive display member 5 has an adhesive layer attached to the surface 5 a, and the surface 5 a is in close contact with the inner side surface of the wall portion 38. In addition, if air remains between the surface 5a and the wall part 38 at the time of this sticking, the display of the temperature sensitive display member 5 cannot be visually recognized from the outside by total reflection. Therefore, stick with care not to leave any air. Moreover, by sticking in this way, the back surface 5b of the temperature-sensitive display member 5 can be in direct contact with the cleaning liquid. Therefore, the temperature of the cleaning liquid is immediately transmitted from the back surface 5b to the front surface 5a. On the other hand, the wall portion 38 functions as a heat insulating wall so that the influence of the hot water temperature on the bathtub side does not affect the temperature sensitive display member 5.

  For example, as shown in FIG. 14, nothing is displayed on the surface 5 a of the temperature-sensitive display member 5 in a temperature range of 40 ° C. or less (FIG. 14A), but “appropriate temperature” in the temperature range of 50 to 60 ° C. Is displayed ((b)). When the temperature further increases to 70 to 80 ° C., “high temperature” is displayed. If the temperature is further increased, the temperature becomes unsuitable for cleaning, so that further heating is unnecessary. Therefore, “fire extinguishing” is displayed larger ((d)). In addition to the display of such characters, symbols and numbers may be displayed, or the temperature of the cleaning liquid may be made visible by a change in color.

  Returning to FIG. 13, in the embodiment shown in this figure, the short suction cups 26 a are provided above the left and right long suction cups 26, respectively. The length of the short suction cup 26a is preferably about 40% to 70% of the long suction cup 26. And by providing the short suction cup 26a in this way, it will be hold | maintained by five suction cups, and even if any one suction cup will come off, there is no possibility that the whole may drop out. In addition, by adopting the short suction cup 36a having a smaller suction area than the long suction cup 36, the total suction force does not increase so much, and a large force is not required when pulling away from the wall surface of the bathtub BT. Further, since the seal portion 22 is protruded above the short suction cup 26a by the distance S, when peeling from above, the upper end portion of the seal portion 22 is first separated from the bathtub BT, and then the short suction cup 26a is connected to the seal portion. Therefore, the short suction cup 26a can be easily separated from the bathroom BT.

  Further, in the present embodiment, connecting pieces 41 separated from the left and right are provided at three positions at the lower end of the extension plate 4, and the connecting projections 36 a are inserted into the connecting holes 42 formed in the connecting piece 41 so that the extension plate 4 is attached to the main body. I tried to install it.

  However, in the state where the extension plate 4 is attached to the main body, the upper end portion of the extension plate 4 is particularly easily separated from the bathtub BT, so that the upper end width h1 of the skirt portion 43 is wider than the lower end width h2. With this configuration, the upper end portion of the extension plate 4 is prevented from leaving the bathtub BT. The same effect can be obtained even if the upper end of the side surface portion 44 is formed wider than the lower end instead of the skirt portion 43.

  In addition, as in the case shown in FIG. 9, the main body can also be folded in the present embodiment, but if it is simply folded, it will be slightly restored from the fully folded state to the spreading direction by the elastic force of the main body. Accordingly, a storage claw 35b is formed on the wall portion 38 so that the main body does not spread by engaging the storage claw 35b with the base portion 35a of the reinforcing plate 35 as shown in FIG.

  By the way, in the two-hole type bath side, the water temperature in the upper part of the cleaning tool 1 tends to become high as described above. It is only necessary for the operator to always monitor during the cleaning work, but if the worker leaves the bathroom during the cleaning work, the cleaning work should be stopped even if the water temperature in the cleaning tool 1 rises abnormally. I can't.

  As shown in FIG. 16, an opening 6 is provided in the wall portion 38 so that the hot cleaning liquid in the cleaning container 1 is replaced with the cold hot water in the bathtub BT through the opening 6, and the temperature in the cleaning container 1 is changed. I tried not to get too hot. However, it is desirable that the opening 6 is closed until the temperature in the cleaning container 1 becomes high.

  Therefore, the opening 6 is closed with a heat-shrinkable resin film 7. Adhesive materials are adhered to the resin film 7 in the vicinity of the upper and lower ends, and the adhesive film is adhered to an adhesive surface 61 surrounding the opening 6, thereby closing the opening 6 with the resin film 7. It was decided.

  However, as shown in FIG. 17, the width of the sticking surface 61 in the vertical direction was made different between the upper part and the lower part. That is, the vertical dimension X1 of the upper sticking surface was made longer than the vertical dimension X2 of the lower sticking surface. When the temperature in the cleaning container 1 rises and reaches a predetermined temperature, the resin film 7 contracts. In particular, since the amount of shrinkage in the vertical direction is large, the adhesive material is peeled off and the resin film 7 is peeled off from the sticking surface 61. However, when the resin film 7 is completely peeled off, subsequent collection is troublesome. However, since the upper and lower dimensions of the sticking surface 61 are different as described above, only the lower part of the resin film 7 is always peeled off, and the upper part remains stuck on the sticking surface 61.

  Note that the adhesive material need not be used. For example, as shown in FIG. 18, the upper and lower portions of the opening 6 are bent and raised to form the claw portion 62, and the resin film 7 is formed by the wall portion 38 and the claw portion 62. May be sandwiched. Note that the amount of bending of the upper claw 62 may be reduced so that the resin film 7 is more strongly sandwiched by the upper claw 62 than the lower claw 62.

  In addition, as shown in FIG. 19, the door portion 38 a may be formed by cutting the wall portion 38 in a longitudinal U shape in the vertical direction. The door portion 38a is bent outward so as to be opened by an elastic force, and the resin plate 71 is hooked on the door portion 38a so as not to open the door portion 38a. A small hole may be formed in the resin plate 71, and the hole may be held by being engaged with a boss 38b protruding from the back surface of the wall portion 38. And if the temperature in the washing container 1 rises, the resin board 71 will shrink | contract, it will remove | deviate from the door part 38a, and the door part 38a will open.

  In addition, this invention is not limited to an above-described form, You may add a various change in the range which does not deviate from the summary of this invention. For example, in the above embodiment, the base portion 2 and the partition wall portion 3 are formed separately, but may be formed integrally.
