However, the water dispenser is often placed on the floor of the floor or the like. Moreover, if the ground water is wetted by the water when the water dispenser leaks, it will cause corrosion or discoloration of the ground. In particular, when a little water leaks (for example, when water leaks in a manner of leaking a small amount of water), it is difficult for the leaked water to appear in a visible form, so that it is easy to find a leak later, and as a result, corrosion on the ground is likely to occur.

Therefore, the inventors of the present application have studied the provision of a water dispenser bracket as a countermeasure against the ground being wetted. That is, the study sets the water dispenser bracket under the frame of the water dispenser, just in case When the water dispenser leaks, the ground is prevented from getting wet by blocking the water with the water dispenser bracket.

However, when the water dispenser bracket is disposed under the frame of the water dispenser, if the water dispenser bracket is formed of a material that is relatively easy to slide by plastic (hard resin) or metal, the person leans on the water dispenser, or In the event of an earthquake, the frame of the water dispenser will slip on the water dispenser bracket and cause the frame of the water dispenser to fall over.

The problem to be solved by the present invention is to prevent the frame from slipping over the water dispenser bracket and tipping over when the water dispenser bracket is disposed under the frame of the water dispenser.

In order to solve the above problems, in the present invention, the following configuration is adopted for the water dispenser.

A water dispenser comprising: a frame body comprising: a tube wall extending in an up and down direction; a top plate disposed to cover an upper portion of the tube wall; and a bottom plate for covering the above a cold water storage tank is disposed inside the frame; a cold water stopcock for injecting the drinking water in the cold water storage tank to the outside of the frame; and a water dispenser bracket having support a water dispenser mounting surface of the bottom plate of the frame; wherein the bottom plate is made of resin, and a plurality of ribs are formed on the lower surface of the bottom plate to form a plurality of columnar recesses opening downward; The water dispenser mounting surface of the machine bracket is provided with a columnar convex portion embedded in at least one of the plurality of columnar recesses, and the columnar convex portion is fitted to the columnar recess The frame body and the water dispenser bracket are coupled to each other so as not to move horizontally.

In this way, since the relative movement of the frame body and the water dispenser bracket is restricted by the fitting of the columnar convex portion and the columnar concave portion, the frame can be prevented from being placed on the water dispenser when the person leans on the water dispenser or an earthquake occurs. The situation on the frame that slipped and fell over. Also, the resin of the existing water dispenser When the bottom plate has a rib for reinforcement on the lower surface, it can be directly used without following the bottom plate. Moreover, the rib portion provided on the bottom plate of the frame body has both the reinforcing function of the bottom plate and the anti-overturn function of the frame body, and is effective.

Preferably, the columnar projections are provided on the water dispenser mounting surface by two or more of the columnar recesses that are respectively inserted into the plurality of columnar recesses at the separated positions.

In this way, when a moment load (that is, a force in a direction in which the frame rotates in the horizontal plane) acts between the frame and the water dispenser bracket, the frame and the water dispenser bracket can be prevented from moving relative to each other.

Preferably, the water dispenser bracket has a configuration in which a peripheral wall portion provided to surround the water dispenser mounting surface is provided.

In this way, in the event that the water dispenser leaks, the surrounding wall portion surrounding the water dispenser mounting surface blocks the water, so that the ground can be effectively prevented from getting wet.

Preferably, the water dispenser bracket is configured to have a water leakage indicator that changes between a notification state and a non-notification state of water leakage according to presence or absence of water in a region surrounded by the peripheral wall portion.

In this way, since the water leakage indicator changes to the state of the water leakage notification based on the water accumulated in the area surrounded by the peripheral wall portion, the water leakage can be detected early in case of water leakage.

Preferably, the water dispenser bracket further includes a sump extending along the peripheral wall portion between the water dispenser mounting surface and the peripheral wall portion, and the water leakage indicator is disposed to communicate with the sump By.

In this way, it is easy to cause the water on the water dispenser bracket to reach the water leakage indicator through the sump, and the water leakage can be found early.

Preferably, the bottom of the trough of the sump is provided with an inclination which gradually decreases as approaching the water leakage indicator.

In this way, since the water accumulated in the sump is guided by the inclination of the groove bottom of the sump To the leak indicator, the leak indicator also changes to the leak notification state during the period when the amount of water leaking is small. Therefore, water leakage can be found early.

The water dispenser bracket may have a support leg extending downward from the outer peripheral portion of the water dispenser mounting surface so as to form a robot housing space for accommodating the self-propelled cleaning robot between the water dispenser mounting surface and the ground. Constitute.

As described above, when the self-propelled cleaning robot is housed in the robot accommodating space, the water dispenser and the self-propelled cleaning robot are arranged in an up-and-down arrangement, thereby saving space. Therefore, it is easy to ensure the placement of the self-propelled cleaning robot and the water dispenser in a limited living space.

The water dispenser of the present invention restricts the relative movement of the frame body and the water dispenser bracket by the fitting of the columnar convex portion and the columnar concave portion, so that when the person leans on the water dispenser or an earthquake occurs, the water dispenser can be prevented. The frame body slides over the water dispenser bracket and falls over.

As shown in FIG. 5, on the lower surface of the bottom plate 8, a plurality of ribs 35 which are formed to intersect each other so as to form a plurality of columnar recesses 34 opened downward are provided. The bottom plate 8 is formed by injection molding of a resin. Each of the ribs 35 is formed in a plate shape that hangs from the lower surface of the bottom plate 8. Although the figure shows a plurality of ribs 35 arranged in a straight line extending in parallel, and a plurality of linear ribs 35 extending in a line orthogonal to the ribs 35, the ribs 35 are The arrangement is not limited thereto. For example, a plurality of linear ribs 35 extending linearly from the center of the bottom plate 8 and a plurality of ribs 35 extending concentrically with the ribs 35 may be disposed.

As shown in FIG. 3, FIG. 5, and FIG. 6, the water dispenser mounting surface 4a of the water dispenser bracket 4 is provided so as to be embedded in at least one of the columnar recesses 34 of the lower surface of the bottom plate 8. There is a columnar convex portion 36. The columnar convex portion 36 has a shape that restricts the relative movement in the horizontal direction when being embedded in the columnar concave portion 34 (here, the outer surface has a vertical surface 36a parallel to the inner surface 34a extending in the vertical direction of the columnar concave portion 34, And by restricting the horizontally moving surface by contacting the vertical surface 36a with the inner surface 34a, the frame body 3 and the water dispenser bracket 4 are horizontal by the fitting of the columnar convex portion 36 and the columnar concave portion 34. Linked in a way that does not move relative to each other. The horizontal gap between the columnar recessed portion 34 and the columnar convex portion 36 is 2 mm or less, preferably 1 mm or less. Further, the columnar convex portions 36 are provided in the water dispenser mounting surface 4a by two or more (four in the drawing), and are respectively embedded in the plurality of columnar recesses 34 on the lower surface of the bottom plate 8 at the separated positions. Two or more columnar recesses 34.

As shown in FIG. 3 and FIG. 7, the water dispenser bracket 4 has a mounting surface for the water dispenser from which the robot accommodating space 5 for accommodating the self-propelled cleaning robot 2 is formed between the water dispenser mounting surface 4a and the floor surface F. The outer peripheral portion of 4a extends downward and contacts a plurality of support legs 37, 38 of the ground F. The plurality of support legs 37 and 38 include a pair of left and right support legs 37 on the front side of the casing 3 of the water dispenser 1, and a pair of left and right support legs 38 on the rear side of the frame 3. Each of the support legs 37, 38 is formed to be higher than the height of the self-propelled cleaning robot 2. Moreover, the interval between the pair of right and left support legs 37 on the front side is set to be larger than the width of the self-propelled cleaning robot 2, and the self-propelled cleaning robot 2 can pass the left and right pairs from the front side of the water dispenser bracket 4. The support legs 37 are self-propelled into and out of the robot accommodating space 5. Further, the water dispenser bracket 4 has a charging terminal supporting member 39 on the rear side of the robot accommodation space 5.

The self-propelled cleaning robot 2 includes a traveling device 40 for walking on the ground F, a dust collecting device 41 for cleaning the garbage of the ground F, and a built-in rechargeable battery 42, and driving the traveling device with electric power supplied from the rechargeable battery 42 40 and the dust collecting device 41, and automatically walk on the ground F and perform cleaning. In the embodiment, the self-propelled cleaning robot 2 has a circular shape having a diameter of 25 to 35 cm from the top as shown in Fig. 7 .

The robot accommodating 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 accommodating space 5. In the charging terminal 43, the self-propelled cleaning robot 2 is housed in the robot housing space 5, and the charging terminal 44 is provided at a position where the self-propelled cleaning robot 2 is in contact. The charging terminal supporting member 39 supports the charging terminal 43 in such a manner as to restrict the charging terminal 43 from moving rearward. The charging terminal supporting member 39 and the charging terminal 43 can be in contact only, but if the fixing mechanism such as a screw is fixed to each other, the position of the charging terminal 43 is more stable, which is preferable. In addition, when the self-propelled cleaning robot 2 completes the cleaning of the ground F, it returns to the robot accommodating space 5 for charging by itself, and when the self-propelled return cannot be returned, the self-propelled cleaning robot 2 is returned to the robot accommodating space 5 Charge it.

The length in the upper and lower directions of the robot housing space 5 is set to be about 0.5 to 5.0 cm longer than the height of the self-propelled cleaning robot 2. By setting it to be larger than 0.5 cm, the interference between the self-propelled cleaning robot 2 and the water dispenser bracket 4 can be surely prevented, and by setting it to be less than 5.0 cm, the length of the support legs 37, 38 of the water dispenser bracket 4 can be suppressed. Therefore, the posture of the frame 3 of the water dispenser 1 is stabilized. Further, the water dispenser bracket 4 is sized to converge from the upper side to the virtual square having a side length of 50 cm (preferably 45 cm) in order to suppress the occupied area when it is placed on the floor surface F.

As shown in FIG. 8, the water leakage indicator 33 has a floating body housing recess 50 that is open to the upper surface of the water dispenser bracket 4 and extends to the inside of the support leg 37, and a water detecting floating body that is inserted into the floating body housing recess 50. 51. The floating body housing recess 50 is a structure in which water flows from the sump 31 into the floating body housing recess 50 so that the water does not leak to the floor surface F. The water detecting floating body 51 has a head portion 52 and a body portion 53 extending downward from the head portion 52. When there is no water in the floating body housing recess 50, the head portion 52 of the water detecting floating body 51 is exposed to the outside, and the main body portion 53 of the water detecting floating body 51 is hidden in the floating body housing recess 50, and is invisible from the outside.

The water detecting floating body 51 is formed in such a manner that the whole body has a smaller specific gravity than water, as shown in FIG. As shown, when water enters the floating body housing recess 50, it rises due to the buoyancy of water. In the figure, as the water detecting floating body 51, a hollow structure in which the surface is covered with a non-foaming resin is used, and a whole molded body by a foaming resin may be used.

The head 52 of the water detecting floating body 51 is marked with the same color as the surface of the peripheral wall portion 30 of the water dispenser bracket 4. On the other hand, the body portion 53 of the water detecting floating body 51 (that is, the portion exposed from the floating body housing recess 50 when the buoyancy of water rises) is marked with a leaking notice color. When the peripheral wall portion 30 of the water dispenser bracket 4 is marked with a color such as black, gray, white, light blue, or brown, the color of the leaking water is exemplified as a color different from the color of the peripheral wall portion 30 of the water dispenser bracket 4. , for example, red, yellow, etc. Red and yellow can also be marked alternately.

The water leakage indicator 33 changes between the notification state of the water leakage and the non-announce state depending on the presence or absence of water. Specifically, when there is no water in the floating body housing recess 50, as shown in FIG. 8, the water detecting floating body 51 is in a lowered state, so that the body portion 53 attached to the water detecting floating body 51 cannot be seen outside. The leaking water notices the color and becomes a non-reporting state of water leakage. When the water flows into the floating body housing recess 50, as shown in Fig. 9, the water detecting floating body 51 rises due to the buoyancy of the water, and the water leakage marked on the body portion 53 of the water detecting floating body 51 can be seen outside. The notification color is the state of notification of water leakage.

As shown in Fig. 2, in the casing 3 of the water dispenser 1, a power supply line 60 for supplying power to a cooling device 19, a heating device 26, and a control circuit (not shown) for controlling the operation of the devices is provided. The charging terminal 43 is provided with a power supply line 62 for supplying electric power to the rechargeable battery 42 of the self-propelled cleaning robot 2 from the power outlet 61. Further, the charging terminal 43 is provided with a power tap 63 that branches from the power source line 62 and supplies electric power. The power tap 63 is connected to the plug 64 provided at the front end of the power cord 60 of the water dispenser 1.

The water dispenser 1 restricts the relative movement of the frame body 3 and the water dispenser bracket 4 by the fitting of the columnar convex portion 36 and the columnar concave portion 34, so that when the person leans on the water dispenser 1, or an earthquake occurs, The situation in which the frame 3 is prevented from slipping and falling over on the water dispenser bracket 4 is prevented.

Further, when the bottom plate 8 made of resin of the conventional water dispenser 1 has the rib 35 for reinforcement on the lower surface, the water dispenser 1 can be directly used without following the bottom plate 8. Further, the rib 35 provided on the bottom plate 8 of the casing 3 has both the reinforcing function of the bottom plate 8 and the anti-overturning function of the casing 3, and is effective.

Further, the water dispenser 1 is provided with two or more columnar convex portions 36 of the water dispenser mounting surface 4a of the water dispenser bracket 4, and is embedded in a plurality of columnar recesses 34 respectively fitted to the lower surface of the bottom plate 8. When two or more columnar recesses 34 are separated from each other, when a moment load (that is, a force for rotating the frame 3 in the horizontal plane) acts between the frame 3 and the water dispenser bracket 4, The frame 3 is prevented from moving relative to the water dispenser bracket 4.

Moreover, in the case of the water dispenser 1 in the case of water leakage, since the peripheral wall portion 30 surrounding the water dispenser mounting surface 4a blocks the water, the floor surface F can be effectively prevented from being wetted.

Further, since the water dispenser 1 is based on water accumulated in the area surrounded by the peripheral wall portion 30 of the water dispenser bracket 4, the water leakage indicator 33 changes to a leaking state of the leaking water, so that water leakage can be detected early in case of water leakage. . In particular, when the casing 3 of the water dispenser 1 leaks a little water (for example, when water leaks in a manner such as leakage of a small amount of water), it is difficult for the leaked water to appear in a visible form, so that it is easy to find a leak later, and as a result, it is easy to produce Corrosion of the ground F, etc., in this case, water leakage can also be found at an early stage, and corrosion of the ground F can be effectively prevented.

Further, since the water dispenser 1 is provided with the sump 31 that communicates with the water leakage indicator 33 between the water dispenser mounting surface 4a and the peripheral wall portion 30, the water on the water dispenser bracket 4 easily reaches the water leakage through the sump 31. The indicator 33 can detect water leakage at an early stage.

Further, since the water dispenser 1 is attached to the bottom of the tank sump 31 and the bottom of the second sump 32, it is provided with an inclination which gradually decreases as it approaches the water leakage indicator 33, and thus is accumulated in each of the sumpes 31, 32. The water is directed to the water leakage indicator 33, and the water leakage indicator 33 also changes to a water leakage notification state at a stage where the amount of water leaked is small. Therefore, water leaks can be detected as early as possible.

Further, when the water dispenser 1 is attached to the robot accommodating space 5 between the water dispenser mounting surface 4a and the floor F, the water dispenser 1 and the self-propelled cleaning robot 2 are installed. It saves space because it is arranged up and down. Therefore, it is easy to ensure the placement of the self-propelled cleaning robot 2 and the water dispenser 1 in a limited living space.

Further, the water dispenser 1 does not use a plurality of power outlets 61, and the power source of the water dispenser 1 and the charging power source of the self-propelled cleaning robot 2 are secured by a single power outlet 61. Therefore, both the self-propelled cleaning robot 2 and the water dispenser 1 can be provided in a place where the number of the power outlets 61 that can be used is small.

Other examples of the water leakage indicator 33 are shown in Figs. 10 and 11 . The parts corresponding to the above-described embodiments are denoted by the same reference numerals and will not be described.

A water-absorbent polymer 54 is provided in the floating body housing recess 50. The water detecting floating body 51 has a lower end surface 51a opposed to the inner bottom surface 50a of the floating body housing recess 50. The water-absorptive polymer 54 is disposed between the lower end surface 51a of the water detecting floating body 51 and the inner bottom surface 50a of the floating body housing recess 50. The water-absorptive polymer 54 is swelled to 100 times or more of its own weight by absorbing water. As such a water-absorbing polymer 54, a sodium polyacrylate is exemplified.

Similarly to the above-described embodiment, the water leakage indicator 33 changes between the notification state of the water leakage and the non-announce state depending on the presence or absence of water. Specifically, when there is no water in the floating body housing recess 50, as shown in FIG. 10, since the water detecting floating body 51 is in a lowered state, the body portion 53 attached to the water detecting floating body 51 cannot be seen outside. The leaking water informs the color and becomes a non-reporting state of water leakage. Further, when water enters the floating body housing recess 50, as shown in FIG. 11, the water-absorbing polymer 54 in the floating body housing recess 50 absorbs water and expands, and the expanded water-absorbing polymer 54 rises in water detection. The lower end surface 51a of the floating body thereby raises the water detecting floating body 51, and the noticeable color of the water leakage marked on the main body portion 53 of the water detecting floating body 51 is visible outside, and becomes a state of water leakage notification.

When the water leakage indicator 33 shown in FIGS. 10 and 11 is used, the water detecting floating body 51 is raised by the expansion force of the water-absorbing polymer 54, so that the water detecting floating body 51 rises compared with the buoyancy of water. In this case, the water detecting float 51 can be made larger. Therefore, when the water detecting floating body 51 is lifted up by the water absorbing polymer 54, the water detecting floating body 51 is largely protruded from the floating body accommodating recess 50. Out, but can indeed inform the leak.

In the above embodiment, as the water leakage indicator 33, a person who detects the floating body using water is exemplified, and another type of water leakage indicator 33 may be employed. For example, a water leakage indicator 33 that uses a material that is discolored by water can also be used.

Further, in the above embodiment, the water dispenser 1 of the type in which the drinking water is introduced into the cold water storage tank 15 from the replacement raw water container 13 is exemplified, and the present invention can also be applied to introduce drinking water from the sewer via the purified water filter. A water dispenser of the type of cold water storage tank 15.
