Drinking machine

Technical Field

The present invention relates to a water dispenser for supplying drinking water.

Background

Although water dispensers have been mainly used in offices, hospitals, and the like, in recent years, due to increased concerns about safety and health of water, water dispensers have become widespread in general households. Generally, a water dispenser includes: a cabinet, a cold water tank housed inside the cabinet, and a cold water faucet for pouring drinking water in the cold water tank to the outside of the cabinet, and drinking water that is good for drinking can be used whenever the cold water faucet is operated (for example, patent document 1 below).

Disclosure of Invention

However, the water dispenser is often installed on a floor surface such as a wooden floor. In addition, in the case of water leakage in the water dispenser, if the water is applied to the floor surface, the floor surface is corroded or discolored. In particular, when water leaks little by little (for example, when water leaks so that a small amount of water seeps out), the leaked water is hardly visible to the eyes, and therefore, the water leakage is likely to be detected at night, and as a result, corrosion of the floor surface and the like are likely to occur.

Therefore, the inventors of the present application have studied to provide a water dispenser tray as a countermeasure for preventing the floor surface from being wetted. Namely, the following were studied: a water dispenser tray is arranged below the shell of the water dispenser, and the water dispenser tray is used for receiving water in case of water leakage of the water dispenser, so that the floor surface is prevented from being wetted.

However, in the case where the water dispenser tray is provided under the cabinet of the water dispenser, if the water dispenser tray is formed of a material that is relatively easy to slide, such as plastic (hard resin) or metal, the cabinet of the water dispenser may slide on the water dispenser tray and the cabinet of the water dispenser may fall over when a person leans on the water dispenser or an earthquake occurs.

The problems to be solved by the present invention are: when the water dispenser tray is arranged under the shell of the water dispenser, the shell is prevented from sliding on the water dispenser tray and overturning.

In order to solve the above problems, the water dispenser of the present invention has the following structure.

A water dispenser, comprising:

the device comprises a shell, a first sealing ring, a second sealing ring and a sealing ring, wherein the shell is composed of a cylinder wall, a top plate and a bottom plate, the cylinder wall extends along the vertical direction, the top plate is used for sealing the upper part of the cylinder wall, and the bottom plate is used for sealing the lower part of the cylinder wall;

a cold water tank housed inside the cabinet;

a cold water tap which injects drinking water in the cold water tank to the outside of the cabinet; and

a water dispenser tray having a water dispenser mounting surface supporting the bottom plate of the housing,

wherein,

the bottom plate is made of resin, a plurality of reinforcing ribs are provided on a lower surface of the bottom plate, the plurality of reinforcing ribs intersect with each other so that a plurality of columnar recesses open downward are formed,

the water dispenser tray is characterized in that the water dispenser mounting surface of the water dispenser tray is provided with columnar convex parts embedded in at least 1 columnar concave part of the columnar concave parts, and the shell and the water dispenser tray are connected through the embedding of the columnar convex parts and the columnar concave parts, so that the shell and the water dispenser tray cannot move horizontally relative to each other.

Therefore, the relative movement of the shell and the water dispenser tray is limited by the embedding of the columnar convex part and the columnar concave part, so that the shell can be prevented from sliding on the water dispenser tray and overturning when a person leans against the water dispenser or an earthquake occurs. In addition, when the lower surface of the resin bottom plate of the existing water dispenser is provided with a reinforcing rib, the bottom plate can be directly used without additional processing. In addition, the reinforcing ribs provided on the bottom plate of the casing are effective in simultaneously achieving the function of reinforcing the bottom plate and the function of preventing the casing from falling over.

Preferably, the 2 or more columnar protrusions are provided on the drinking water machine installation surface so as to be fitted into 2 or more columnar recesses located at positions separated from each other among the plurality of columnar recesses.

Therefore, even if moment load (namely force in the direction of rotating the water dispenser in the horizontal plane) acts between the shell and the water dispenser tray, the shell and the water dispenser tray can be prevented from moving relatively.

Preferably, the following configuration is adopted: the water dispenser tray has a peripheral wall portion configured to surround the water dispenser mounting face.

Therefore, in case of water leakage of the water dispenser, the peripheral wall part surrounding the built-in surface of the water dispenser blocks water, so that the floor surface can be effectively prevented from being wetted.

Preferably, the following structure is adopted: the water dispenser tray has a water leakage indicator in an area surrounded by the peripheral wall portion, and the water leakage indicator changes between a water leakage warning state and a non-warning state according to the presence or absence of water.

Thus, the water leakage indicator changes to a state of warning notification of water leakage in response to water accumulated in the area surrounded by the peripheral wall portion, and therefore, in the event of water leakage, water leakage can be detected early.

Preferably, the following structure is adopted: the water dispenser tray further includes a water collection groove, the water leakage indicator is disposed in communication with the water collection groove, and the water collection groove extends along the peripheral wall portion between the water dispenser mounting surface and the peripheral wall portion.

Therefore, water on the water dispenser tray can easily reach the water leakage indicator through the water collecting groove, and water leakage can be found out early.

Preferably, the trough bottom of the water collection trough is provided with an inclination arranged to: gradually decreasing as the water leak indicator is approached.

Thus, the water leakage indicator is guided to the water leakage indicator by the inclination of the bottom of the water collection tank, and thus the water leakage indicator is in a water leakage warning state even when the amount of water leakage is small. Therefore, water leakage can be detected early.

In addition, the following structure may be adopted: the water dispenser tray is provided with supporting legs extending downwards from the outer peripheral part of the water dispenser carrying surface, so that a robot accommodating space for accommodating the self-propelled cleaning robot is formed between the water dispenser carrying surface and the floor surface.

Thus, when the self-propelled cleaning robot is accommodated in the robot accommodating space, the water dispenser and the self-propelled cleaning robot are arranged in the vertical direction, thereby saving space. Therefore, the placement positions of the self-propelled cleaning robot and the water dispenser can be easily secured even in a limited living space.

The water dispenser limits the relative movement of the shell and the water dispenser tray through the embedding of the columnar convex part and the columnar concave part, so that the shell of the water dispenser can be prevented from sliding on the water dispenser tray and overturning when people lean against the water dispenser or an earthquake occurs.

The water dispenser 1 includes a housing 3 and a water dispenser tray 4, the housing 3 being disposed above a horizontal floor surface F, the water dispenser tray 4 being configured to: the housing 3 is spaced from the floor surface F up and down. A robot housing space 5 into which the self-propelled cleaning robot 2 is to be moved is formed between the water fountain tray 4 and the floor surface F.

As shown in fig. 2, the water dispenser 1 includes a housing 3, and the housing 3 includes a cylindrical wall 6 extending in the vertical direction, a top plate 7 provided to close an upper portion of the cylindrical wall 6, and a bottom plate 8 provided to close a lower portion of the cylindrical wall 6. The tubular wall 6 is composed of a pair of left and right side panels 10, a front panel 11 connecting front edges of the side panels 10 to each other, and a rear panel 12 connecting rear edges of the side panels 10 to each other. In the present embodiment, the tubular wall 6 is formed in a square tubular shape having a substantially square outer periphery, but may be formed in a cylindrical shape having a substantially circular outer periphery.

A replaceable raw water tank 13 is detachably attached to the top plate 7 of the housing 3. The raw water tank 13 is placed on the top plate 7 of the housing 3 in a posture in which the water outlet 14 is directed downward. The capacity of the raw water container 13 is about 8 to 20 liters in a full water state. A water inlet pipe 16 for introducing drinking water from the raw water tank 13 placed on the top plate 7 into the cold water tank 15 inside the cabinet 3 is provided on the top plate 7 of the cabinet 3. A decorative cover 17 covering the raw water tank 13 is attached to the upper portion of the housing 3.

A cold water tank 15 for storing low-temperature drinking water and a warm water tank 18 for storing high-temperature drinking water are stored in the housing 3. The cold water tank 15 is provided with a cooling device 19 for cooling the drinking water stored in the cold water tank 15. The cooling device 19 is configured to: a refrigerant pipe 20 wound around the outer periphery of the cold water tank 15, a compressor 21 fixed to the bottom plate 8 of the casing 3, and a condenser 22 fixed to the rear panel 12 of the casing 3 are connected by a pipe 23. The refrigerant pipe 20 is cooled to about-15 to-30 ℃ by the operation of the compressor 21, and keeps the temperature of the drinking water in the cold water tank 15 low (about 5 ℃).

A cold water outlet pipe 24 for discharging the low-temperature drinking water in the cold water tank 15 to the outside of the cabinet 3 is connected to the bottom surface of the cold water tank 15. A cold water tap 25 operable from the outside of the cabinet 3 is provided in the cold water pouring pipe 24, and low-temperature drinking water can be poured from the cold water tank 15 into a cup or the like by opening the cold water tap 25. The volume of the drinking water in the cold water tank 15 is smaller than that of the raw water container 13, and is about 2-4 liters.

The warm water tank 18 is disposed below the cold water tank 15. A heating device 26 for heating the drinking water stored in the hot water tank 18 is attached to the hot water tank 18. Although the example in which the sheathed heater is used as the heating device 26 is shown in the figure, a band heater may be used. The sheathed heater is obtained by housing a heating wire that generates heat when energized in a metal pipe, and is attached so as to penetrate the wall surface of the hot water tank 18 and extend inside the hot water tank 18. The band heater is a cylindrical heating element in which a heating wire for generating heat by energization is embedded, and is attached to the outer periphery of the warm water tank 18 in close contact therewith. The heating device 26 keeps the drinking water in the warm water tank 18 at a high temperature (about 90 ℃).

A hot water supply passage 27 for supplying the high-temperature drinking water in the hot water tank 18 to the outside of the housing 3 is connected to the upper surface of the hot water tank 18. A hot water tap 28 operable from the outside of the cabinet 3 is provided in the hot water discharge path 27, and high-temperature drinking water can be discharged from the hot water tank 18 to a cup or the like by opening the hot water tap 28. The hot water faucet 28 is disposed on the front side of the cabinet 3 in the same manner as the cold water faucet 25. The capacity of the warm water tank 18 is about 1-2 liters.

The cold water tank 15 and the warm water tank 18 are communicated with each other via a tank connection pipe 29, and if drinking water is poured out from the warm water tank 18, the same amount of drinking water as the drinking water flows into the warm water tank 18 from the cold water tank 15 via the tank connection pipe 29, and the warm water tank 18 is always kept in a full water state.

As shown in fig. 3 and 4, the water dispenser tray 4 includes: a water fountain installation surface 4a that supports the bottom plate 8 of the casing 3, a peripheral wall portion 30 that is provided so as to surround the water fountain installation surface 4a when viewed from above, a water collection tank 31 that extends along the peripheral wall portion 30 between the water fountain installation surface 4a and the peripheral wall portion 30, a second water collection tank 32 that extends so as to communicate between the center of the water fountain installation surface 4a and the water collection tank 31, and a water leakage indicator 33 that is disposed in a region surrounded by the peripheral wall portion 30.

The water dispenser placement surface 4a is a surface having an area equal to or larger than the area of the bottom plate 8 of the casing 3, so that the water dispenser placement surface 4a can stably support the casing 3 placed on the water dispenser placement surface 4 a. In the figure, the water dispenser installation surface 4a is a horizontal plane. The peripheral wall portion 30 has a shape in which a portion protruding to a position higher than the water fountain placement surface 4a is continuously formed so as to surround the water fountain placement surface 4a, and can trap water to a position higher than the water fountain placement surface 4a in the event of water leakage from the casing 3 placed on the water fountain placement surface 4 a.

As shown in fig. 4, the water collection tank 31 extends annularly so as to surround the bottom plate 8 of the housing 3 of the water dispenser 1 when viewed from above. The second water collection tank 32 extends from directly below the bottom plate 8 of the cabinet 3 of the water dispenser 1 to the outside of the bottom plate 8, and communicates with the water collection tank 31. The water leakage indicator 33 is arranged at the front side of the casing 3 of the water dispenser 1, and the water collecting tank 31 is configured as follows: communicating with the water leak indicator 33. The bottom of the water collection tank 31 and the bottom of the second water collection tank 32 are inclined: the water gradually decreases as it approaches the water leakage indicator 33, and the water is guided to the water leakage indicator 33 by the inclination of the bottom of each of the water collecting grooves 31 and 32 regardless of the part of the water collecting groove 31 or the second water collecting groove 32 into which the water flows.

As shown in fig. 5, a plurality of ribs 35 are provided on the lower surface of the bottom plate 8, and the plurality of ribs 35 intersect with each other so that a plurality of columnar recesses 34 open downward are formed. The bottom plate 8 is formed by resin injection molding. Each rib 35 is formed in a plate shape that hangs down from the lower surface of the bottom plate 8. In the figure, an example is shown in which a plurality of straight ribs 35 extending in parallel and a plurality of straight ribs 35 extending so as to be orthogonal to the ribs 35 are arranged, but the arrangement of the ribs 35 is not limited to this, and for example, a plurality of straight ribs 35 extending radially from the center of the bottom plate 8 and a plurality of ribs 35 extending concentrically with the ribs 35 may be arranged.

As shown in fig. 3 and 6, on the water fountain installation surface 4a of the water fountain tray 4, columnar protrusions 36 are provided so as to fit into at least 1 of the columnar recesses 34 on the lower surface of the bottom plate 8. The columnar protrusion 36 is shaped to restrict relative movement in the horizontal direction when fitted into the columnar recess 34 (here, a shape having a vertical surface 36a parallel to an inner surface 34a extending in the vertical direction of the columnar recess 34 on the outer periphery and restricting horizontal movement by the contact of the vertical surface 36a with the inner surface 34 a), and the fitting of the columnar protrusion 36 with the columnar recess 34 connects the housing 3 and the water fountain tray 4 so that the both do not move horizontally relative to each other. The horizontal play between the columnar recesses 34 and the columnar protrusions 36 is 2mm or less, preferably 1mm or less. In addition, 2 or more (4 in the figure) columnar projections 36 are provided: and 2 or more columnar recesses 34 at positions separated from each other, of the plurality of columnar recesses 34 fitted to the lower surface of the bottom plate 8.

As shown in fig. 3 and 7, the water fountain tray 4 includes a plurality of support legs 37 and 38 extending downward from the outer peripheral portion of the water fountain installation surface 4a and contacting the floor surface F, so that a robot housing space 5 housing the self-propelled cleaning robot 2 is formed between the water fountain installation surface 4a and the floor surface F. The support legs 37 and 38 are composed of a pair of left and right support legs 37 located on the front side of the housing 3 of the water dispenser 1 and a pair of left and right support legs 38 located on the rear side of the housing 3. Each of the support legs 37 and 38 is formed as: is longer than the height of the self-propelled cleaning robot 2. The distance between the pair of front left and right support legs 37 is set as follows: is wider than the self-propelled cleaning robot 2, so that the self-propelled cleaning robot 2 can pass between the pair of left and right support legs 37 from the front side of the water dispenser tray 4 and enter and exit the robot housing space 5 by itself. Further, the water dispenser tray 4 has a charging terminal support member 39 on the rear side of the robot housing space 5.

The self-propelled cleaning robot 2 includes: the cleaning robot includes a traveling device 40 for traveling the self-propelled cleaning robot 2 on the floor surface F, a dust collecting device 41 for removing dust on the floor surface F, and a built-in rechargeable battery 42, and the traveling device 40 and the dust collecting device 41 are driven by electric power supplied from the rechargeable battery 42 to automatically travel on the floor surface F for cleaning. In the present embodiment, the self-propelled cleaning robot 2 has a circular shape with a diameter of 25 to 35cm when viewed from above, as shown in fig. 7. The height of the floor surface F from the upper surface is set to 5-10 cm when the self-propelled cleaning robot 2 is traveling on the floor surface F.

The robot housing space 5 is provided with a charging terminal 43 that charges the rechargeable battery 42 in a state where the self-propelled cleaning robot 2 is housed in the robot housing space 5. The charging terminal 44 is provided at a position of the charging terminal 43 that contacts the self-propelled cleaning robot 2 in a state where the self-propelled cleaning robot 2 is housed in the robot housing space 5. The charging terminal support member 39 supports the charging terminal 43 so as to restrict the charging terminal 43 from moving rearward. The charging terminal support member 39 and the charging terminal 43 may be merely in contact, and if they are fixed to each other by a fixing mechanism such as a screw, the position of the charging terminal 43 is more stable, which is highly desirable. Note that, the self-propelled cleaning robot 2 returns to the robot housing space 5 by itself and is charged when the cleaning of the floor surface F is completed, but when the self-propelled cleaning robot 2 is not returned by itself, the self-propelled cleaning robot 2 is returned to the robot housing space 5 and is charged.

The width of the robot housing space 5 in the vertical direction is set to: about 0.5 to 5.0cm greater than the height of the self-propelled cleaning robot 2. By setting the distance to be greater than 0.5cm, interference between the self-propelled cleaning robot 2 and the water fountain tray 4 can be reliably prevented, and by setting the distance to be less than 5.0cm, the lengths of the support legs 37 and 38 of the water fountain tray 4 can be suppressed, and the posture of the housing 3 of the water fountain 1 can be stabilized. The water fountain tray 4 is sized to be accommodated in a virtual square having a side length of 50cm (preferably 45cm) when viewed from above, so as to suppress an occupied area when installed on the floor surface F.

As shown in fig. 8, the water leakage indicator 33 includes: a float receiving recess 50 opened on the upper surface of the water dispenser tray 4 and extending along the inside of the support leg 37, and a water detection float 51 inserted into the float receiving recess 50. The structure of the float receiving recess 50 is: when water flows into the float receiving recess 50 from the water collection tank 31, the water is trapped inside so that the water does not leak to the floor surface F. The water detection float 51 includes a head portion 52 and a body portion 53 extending downward from the head portion 52. When there is no water in the float housing recess 50, the head 52 of the water detection float 51 is exposed to the outside, and the body 53 of the water detection float 51 is hidden in the float housing recess 50, so that it is not visible from the outside.

The water detection float 51 is formed as: as a whole, the specific gravity is lower than that of water, and when water enters the float receiving recess 50, the water rises due to the buoyancy of the water, as shown in fig. 9. Although the water detection float 51 has a hollow structure with its surface covered with a non-foamed resin in the drawing, it may be formed entirely of a foamed resin.

The head 52 of the water detection float 51 is colored in the same color as the surface of the peripheral wall 30 of the water dispenser tray 4. On the other hand, the body portion 53 of the water detection float 51 (i.e., the portion exposed from the float storage recess 50 when the buoyancy of water increases) is colored with a warning color of water leakage. When the peripheral wall portion 30 of the water dispenser tray 4 is colored in black, gray, white, light blue, brown, or the like, the color for warning of water leakage may be different from the color of the peripheral wall portion 30 of the water dispenser tray 4, for example, red, yellow, or the like. It is also possible to impart red and yellow alternately.

The water leakage indicator 33 changes between a water leakage warning state and a non-warning state depending on the presence or absence of water. Specifically, when there is no water in the float housing recess 50, the water detection float 51 is in a lowered state as shown in fig. 8, and therefore the water leakage warning color of the main body 53 of the water detection float 51 is not visible from the outside, and the water leakage non-warning state is achieved. When water enters the float receiving recess 50, as shown in fig. 9, the water detection float 51 rises due to the buoyancy of the water, and the water leakage warning color of the body portion 53 of the water detection float 51 is visible from the outside, thereby setting the water leakage warning state.

As shown in fig. 2, a housing 3 of the water dispenser 1 is provided with a power supply line 60 for supplying power to the cooling device 19, the heating device 26, and a control circuit, not shown, for controlling operations of these devices. The charging terminal 43 is provided with a power cord 62 for supplying power from the power outlet 61 to the rechargeable battery 42 of the self-propelled cleaning robot 2. The charging terminal 43 is provided with a power tap 63 that is branched from the power cord 62 and supplies power. A plug 64 provided at the tip of the power cord 60 of the water dispenser 1 is connected to the power tap 63.

In the water dispenser 1, the relative movement of the casing 3 and the water dispenser tray 4 is limited by the embedding of the columnar convex part 36 and the columnar concave part 34, so that the casing 3 can be prevented from sliding on the water dispenser tray 4 and overturning when a person leans against the water dispenser 1 or an earthquake occurs.

In the water dispenser 1, when the reinforcing rib 35 is provided on the lower surface of the resin bottom plate 8 of the conventional water dispenser 1, the bottom plate 8 can be used as it is without additional processing. In addition, the reinforcing rib 35 provided on the bottom plate 8 of the housing 3 is effective in achieving both the function of reinforcing the bottom plate 8 and the function of preventing the housing 3 from falling over.

In addition, in the water dispenser 1, the 2 or more columnar projections 36 of the dispenser mounting surface 4a of the dispenser tray 4 are provided: the columnar recesses 34 are fitted into the columnar recesses 34 on the lower surface of the bottom plate 8 at positions spaced apart from each other by 2 or more, and therefore, even if a moment load (i.e., a force in a direction of rotating the housing 3 in a horizontal plane) acts between the housing 3 and the water fountain tray 4, the housing 3 and the water fountain tray 4 can be prevented from moving relative to each other.

In addition, in the water dispenser 1, the peripheral wall portion 30 surrounding the dispenser installation surface 4a blocks water in the event of water leakage, and therefore the floor surface F can be effectively prevented from being wetted.

In the water dispenser 1, the water leakage indicator 33 changes to a water leakage warning state according to the water accumulated in the area surrounded by the peripheral wall portion 30 of the water dispenser tray 4, and therefore, in the event of water leakage, water leakage can be detected early. In particular, when the casing 3 of the water dispenser 1 leaks a little by little (for example, when a slight amount of water seeps), the leaked water is hardly visible to the eyes, and therefore, the leakage is likely to be detected at a late date, and as a result, corrosion of the floor surface F is likely to occur.

In the water dispenser 1, the water collection tank 31 communicating with the water leakage indicator 33 is provided between the dispenser mounting surface 4a and the peripheral wall portion 30, so that water on the dispenser mounting surface 4a easily reaches the water leakage indicator 33 through the water collection tank 31, and water leakage can be detected early.

In addition, in the water dispenser 1, the bottom of the water collection tank 31 and the bottom of the second water collection tank 32 are inclined such that: since the water level gradually decreases as it approaches the water leakage indicator 33, the water accumulated in the water collecting tanks 31 and 32 is guided to the water leakage indicator 33, and the water leakage indicator 33 is in a water leakage warning state even when the water leakage amount is small. Therefore, water leakage can be found extremely early.

In the water dispenser 1, when the self-propelled cleaning robot 2 is housed in the robot housing space 5 between the dispenser installation surface 4a and the floor surface F, the water dispenser 1 and the self-propelled cleaning robot 2 are arranged vertically, and therefore space is saved. Therefore, the placement positions of the self-propelled cleaning robot 2 and the water dispenser 1 can be easily secured even in a limited living space.

In addition, in the water dispenser 1, it is not necessary to use a plurality of power outlets 61, and the power for the water dispenser 1 and the power for charging the self-propelled cleaning robot 2 can be secured by a single power outlet 61. Therefore, even in a place where the number of available power outlets 61 is small, both the self-propelled cleaning robot 2 and the water dispenser 1 can be installed.

Fig. 10 and 11 show another example of the water leakage indicator 33. The same reference numerals are given to portions corresponding to those of the above embodiments, and the description thereof will be omitted.

A water-absorbent polymer 54 is provided in the float receiving recess 50. The water detection float 51 has a lower end surface 51a facing the inner bottom surface 50a of the float receiving recess 50. The water-absorbent polymer 54 is disposed between the lower end surface 51a of the water detection float 51 and the inner bottom surface 50a of the float receiving recess 50. The water-absorbent polymer 54 absorbs water and swells 100 times or more its own weight. Examples of the water-absorbent polymer 54 include sodium polyacrylate.

The water leakage indicator 33 is also changed between a water leakage warning state and a non-warning state depending on the presence or absence of water, as in the above-described embodiment. Specifically, when there is no water in the float housing recess 50, the water detection float 51 is in a lowered state as shown in fig. 10, and therefore the water leakage warning color of the main body 53 of the water detection float 51 is not visible from the outside, and the water leakage non-warning state is achieved. When water enters the float receiving recess 50, as shown in fig. 11, the water-absorbent polymer 54 in the float receiving recess 50 absorbs water and swells, and the swollen water-absorbent polymer 54 pushes up the lower end surface 51a of the water detection float, so that the water detection float 51 rises, and the water leakage warning color of the body portion 53 of the water detection float 51 is visible from the outside, thereby achieving a water leakage warning state.

When the water leakage indicator 33 shown in fig. 10 and 11 is used, the water detection float 51 is raised by the expansion force of the water-absorbent polymer 54, and therefore, the water detection float 51 can be raised significantly as compared with the case where the water detection float 51 is raised by the buoyancy of water. Therefore, when the water detection float 51 is pushed up by the water-absorbent polymer 54, the water detection float 51 protrudes largely from the float housing recess 50, and the water leakage can be reliably notified.

In the above embodiment, the water leakage indicator 33 is described by taking as an example a water leakage indicator using a water detection float, but other types of water leakage indicators 33 may be used. For example, a water leak indicator 33 using a material that changes color if wetted with water may be used.
