JP 2011-046446 A

  Installing a water server in a living room or dining room is convenient because you can use drinking water at any time. However, the water server's housing occupies a part of the indoor space of the living room and dining room. Will do. That is, the space occupied by the water server becomes a useless dead space while not using drinking water.

  Here, the inventor can only use delicious drinking water at any time without using drinking water as long as the indoor air of the living room or dining room can be purified using the space occupied by the water server. In addition, the room air in the living room and dining room became delicious, and I realized the possibility of realizing a very comfortable indoor environment.

  The problem to be solved by the present invention is to provide a water server capable of realizing a very comfortable indoor environment in a limited living space.

In order to solve the above problems, the present invention provides a water server having the following configuration.
A casing comprising a cylindrical wall extending in the vertical direction, a top plate provided so as to close an upper portion of the cylindrical wall, and a bottom plate provided so as to close a lower portion of the cylindrical wall;
A cold water tank and a hot water tank housed in the housing;
A cooling device for cooling the drinking water in the cold water tank;
A heating device for heating the drinking water in the hot water tank;
A cold water faucet and a hot water faucet disposed on the front side of the housing;
A cold water pouring path communicating between the cold water tank and the cold water faucet;
In a water server having a hot water pouring path communicating between the hot water tank and the hot water faucet,
An air suction port for sucking air outside the housing, a filter for purifying air sucked from the air suction port, and an air outlet for discharging the air purified by the filter to the outside of the housing A water server characterized in that an air purifier is provided in the casing.

  If it does in this way, even if it does not utilize drinking water, it will become possible to purify air with the air cleaner accommodated in the case of the water server. Therefore, by installing this water server in the living room or dining room, it is possible not only to use delicious drinking water at any time, but also the indoor air in the living room and dining room will be delicious. An extremely comfortable indoor environment can be realized.

  As the cooling device, a compressor fixed on the bottom plate of the housing, a heat exchanger for exchanging heat between the high-temperature refrigerant discharged from the compressor and the outside air, and the heat exchanger passed An expansion valve that reduces the temperature by depressurizing the refrigerant, and a cooling pipe that is wound around the outer periphery of the cold water tank so as to exchange heat between the low-temperature refrigerant that has passed through the expansion valve and the cold water tank Things can be adopted. In this case, it is preferable that the air purifier is arranged in a region below the cold water tank and the hot water tank and above the compressor in the space in the housing.

  If it does in this way, the head of drinking water for moving drinking water from a cold water tank and a warm water tank to a cold water faucet and a warm water faucet can be secured, accommodating an air cleaner inside the case.

  As the heat exchanger, a metal serpentine tube formed by bending so as to move the refrigerant from above to below while reciprocating left and right along the rear surface of the housing can be adopted. In this case, the air inlet and the air outlet can be provided such that the air inlet opens on the rear surface side of the casing and the air outlet opens on the front side of the casing. Then, since the air suction port is located on the same side as the rear surface side of the housing where the serpentine tube is located, dust contained in the air moving toward the air suction port adheres to the serpentine tube, and the attached dust The heat exchange efficiency of the serpentine tube may be reduced. Therefore, it is preferable that the air inlet and the air outlet are provided so as to open to the front side of the casing.

  In this case, since the air suction port is located on the opposite side (front side of the housing) to the rear surface side of the housing where the serpentine tube is located, dust contained in the air moving toward the air suction port A situation of adhering to the tube can be prevented, and a decrease in heat exchange efficiency of the serpentine tube due to adhesion of dust can be prevented.

  When the filter is a planar member, it is possible to assemble the filter in a direction orthogonal to the front-rear direction of the housing, but in this way, it is difficult to ensure the area of the filter, and the air purification function It is difficult to secure. Therefore, the upstream side air passage that connects the air suction port and the filter is assembled by assembling the filter in a direction intersecting the left and right direction of the housing so that the direction in which the air passes through the filter is the left and right direction of the housing. It is preferable to employ a layout in which a downstream air passage that communicates between the filter and the air outlet is provided. If it does in this way, it will become easy to ensure the area of a filter, and it will become possible to secure the purification function of air.

  The air cleaner is preferably removable from the housing. If it does in this way, cleaning and maintenance of an air cleaner will become easy by removing an air cleaner from a case.

  The water server of the present invention can purify the air with an air purifier housed in the housing of the water server even when drinking water is not used. Therefore, by installing this water server in the living room or dining room, it is possible not only to use delicious drinking water at any time, but also the indoor air in the living room and dining room will be delicious. An extremely comfortable indoor environment can be realized.

The figure which looked at the water server of this embodiment from the front side Sectional view along the line II-II in FIG. Sectional drawing of the vicinity of the air cleaner of the water server shown in FIG.

  FIG. 1 shows a water server 1 according to an embodiment of the present invention. The water server 1 is housed in the casing 2, which is disposed on the horizontal floor F and has a vertically elongated casing 2, a cold water faucet 3 and a hot water faucet 4 disposed on the front side of the casing 2, and the casing 2. The air purifier 5 is provided.

  As shown in FIG. 2, the housing 2 is provided so as to close the cylindrical wall 6 extending in the vertical direction, the top plate 7 provided to close the upper part of the cylindrical wall 6, and the lower part of the cylindrical wall 6. And a bottom plate 8. The cylindrical wall 6 includes a pair of left and right side plates 9, a front plate 10 that connects the front edges of the side plates 9, and a rear plate 11 that connects the rear edges of the side plates 9. The front-rear direction is the front side and the back side is the rear side as viewed from the user who pours drinking water from the cold water tap 3 or the hot water tap 4.

  A replaceable raw water container 12 is detachably set on the top plate 7 of the housing 2. The raw water container 12 is placed on the top plate 7 with the water outlet 13 facing downward. The capacity of the raw water container 12 is about 10 to 20 liters in a full water state. The raw water container 12 is formed with flexibility so as to contract as the amount of residual water inside decreases. A cold water tank 14 and a hot water tank 15 are accommodated in the housing 2. The top plate 7 is provided with a raw water introduction pipe 16 for introducing drinking water from the raw water container 12 to the cold water tank 14.

  One end of the raw water introduction pipe 16 is detachably connected to the raw water container 12, and the other end of the raw water introduction pipe 16 is fixedly connected to the cold water tank 14. A float valve 17 that opens and closes according to the water level in the cold water tank 14 is provided at the end of the raw water introduction pipe 16 on the cold water tank 14 side. When the raw water container 12 is of a type formed with rigidity so as not to be deformed even if the amount of residual water inside is reduced, the float valve 17 is unnecessary. In this case, the water level in the cold water tank 14 is the same height as the end of the raw water introduction pipe 16 on the cold water tank 14 side. A decorative cover 18 that covers the raw water container 12 is attached to the top of the housing 2.

  The cold water tank 14 is provided with a cooling device 20 for cooling the drinking water stored in the cold water tank 14. The cooling device 20 includes a compressor 21, a heat exchanger 22, an expansion valve 23, and a cooling pipe 24. The compressor 21 is fixed on the bottom plate 8 of the housing 2. The heat exchanger 22 is a metal serpentine tube formed by bending so as to move the refrigerant from above to below while reciprocating left and right along the rear surface of the housing 2. The compressor 21, the heat exchanger 22, the expansion valve 23, and the cooling pipe 24 are connected by a refrigerant pipe so that the refrigerant passes through and circulates in order. The cooling pipe 24 is spirally wound around the lower outer periphery of the cold water tank 14.

  The compressor 21 sucks the refrigerant from the cooling pipe 24, compresses the refrigerant to increase the temperature of the refrigerant, and discharges the refrigerant that has become high temperature and pressure to the heat exchanger 22 side. The heat exchanger 22 receives the high-temperature and high-pressure refrigerant discharged from the compressor 21 and performs heat exchange between the refrigerant and the outside air. The expansion valve 23 receives the refrigerant that has passed through the heat exchanger 22 and depressurizes the refrigerant to lower the temperature. The cooling pipe 24 receives the low-temperature and low-pressure refrigerant that has passed through the expansion valve 23, and performs heat exchange between the refrigerant and the cold water tank 14. The compressor 21 operates when the temperature of the cold water tank 14 becomes higher than a predetermined threshold value. At this time, the cooling pipe 24 becomes a low temperature of minus 15 ° C. to minus 30 ° C., and the drinking water in the cold water tank 14 is discharged. Cool down. In this way, the drinking water in the cold water tank 14 is kept at a predetermined low temperature (about 5 ° C.).

  One end of a cold water pouring channel 25 communicating between the cold water tank 14 and the cold water faucet 3 is connected to the bottom surface of the cold water tank 14, and a cup of low-temperature drinking water from the cold water tank 14 is opened by the operation of opening the cold water faucet 3. Can be poured into Here, the cold water faucet 3 allows the low temperature drinking water in the cold water tank 14 to be poured out of the cold water faucet 3 through its cold water outlet channel 25 by its own weight (that is, without using a pump) It is arranged at a position lower than the bottom surface of the cold water tank 14 so that it can be poured out. The capacity of the drinking water in the cold water tank 14 is smaller than the capacity of the raw water container 12 and is about 2 to 4 liters.

  The hot water tank 15 is disposed below the cold water tank 14. A heating device 26 for heating the drinking water stored in the hot water tank 15 is attached to the hot water tank 15. In the figure, an example in which a sheathed heater is employed for the heating device 26 is shown, but a band heater can also be employed. The sheathed heater accommodates 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 15 and extend inside the hot water tank 15. The band heater is a cylindrical heating element in which a heating wire that generates heat when energized is embedded, and is attached in close contact with the outer periphery of the hot water tank 15. The heating device 26 keeps the drinking water in the hot water tank 15 at a high temperature (about 90 ° C.).

  Connected to the upper surface of the hot water tank 15 is a hot water pouring path 27 that communicates between the hot water tank 15 and the hot water faucet 4, and hot water is poured from the hot water tank 15 into a cup or the like by opening the hot water faucet 4. It can come out. The capacity of the hot water tank 15 is about 1 to 2 liters.

  The cold water tank 14 and the hot water tank 15 communicate with each other via the tank connection pipe 28, and when drinking water is poured out from the hot water tank 15, the same amount of drinking water as that drinking water passes through the tank connection pipe 28 to The hot water tank 15 flows into the hot water tank 15 from the tank 14 so that the hot water tank 15 is always kept full. Here, the hot water faucet 4 is such that hot drinking water in the hot water tank 15 is poured out from the hot water faucet 4 through the hot water pouring channel 27 by pressure due to the weight of the drinking water in the cold water tank 14 (that is, the pump So that high-temperature drinking water can be poured out without using the water).

  As shown in FIG. 1, the housing 2 is provided with a housing opening 30 for housing the air purifier 5. The accommodation opening 30 opens in the front plate 10 of the housing 2 so that the air cleaner 5 can be attached and detached from the front side of the housing 2. The air purifier 5 is disposed in an area below the cold water tank 14 and the hot water tank 15 and above the compressor 21 in the space in the housing 2.

  As shown in FIG. 3, the accommodation opening 30 includes an inner bottom plate 31 that supports the air cleaner 5 from below, a pair of left and right inner plates 32 that support the air cleaner 5 from the left and right, and an upper side of the inner bottom plate 31. And an inner top plate 33 opposite to the inner top plate 33. The air cleaner 5 includes a case 34 having a size that can be accommodated in the accommodation opening 30 of the housing 2, an air inlet 35 and an air outlet 36 (see FIG. 1) that open to the front surface of the case 34, and a case 34, a filter 37 housed in 34, an upstream ventilation path 38 communicating between the air suction port 35 and the filter 37, a downstream ventilation path 39 communicating between the filter 37 and the air outlet 36, and a downstream side. And a centrifugal fan 40 provided in the middle of the ventilation path 39.

  The filter 37 is a flat member formed of fibers so as to have air permeability, and when air is passed through the filter 37, the filter 37 captures dust and fine particles in the air, so that the air is collected. Purify. The filter 37 is incorporated in a direction intersecting the left-right direction of the housing 2 such that the direction in which air passes through the filter 37 is the left-right direction of the housing 2. As such a planar filter 37, for example, a bellows-like filter member in which a sheet-like filter medium is folded so as to be stacked in the front-rear direction or the vertical direction of the housing 2 can be employed. In the figure, the direction of the filter 37 is orthogonal to the left-right direction of the housing 2, but it is also possible to make the direction obliquely intersect with the left-right direction of the housing 2.

  The air suction port 35 is disposed below the filter 37, and an upstream air passage 38 is provided in an L shape so as to communicate between the air suction port 35 and the filter 37. The air outlet 36 is disposed above the filter 37, and a downstream side air passage 39 is provided in an L shape so as to communicate between the air outlet 36 and the filter 37.

  The centrifugal fan 40 includes an electric motor 41 and a cylindrical impeller 42 that is rotationally driven by the electric motor 41. The impeller 42 is disposed adjacent to the filter 37 so as to rotate around an axis parallel to the horizontal direction of the housing 2. When the impeller 42 rotates, a negative pressure generated inside the impeller 42 causes a flow of air from the upstream side air passage 38 to the downstream side air passage 39 through the filter 37. At this time, air outside the housing 2 is sucked into the case 34 from the air suction port 35, and the air passes through the upstream side air passage 38, the filter 37, and the downstream side air passage 39 in this order from the air outlet 36. It is discharged to the outside of the case 34 (outside the housing 2).

  The water server 1 can purify air with the air purifier 5 accommodated in the housing 2 of the water server 1 even when drinking water is not used. For this reason, installing this water server 1 in a living room or dining room will not only allow you to use delicious drinking water at any time, but also make the indoor air in the living room and dining room delicious, resulting in limited living space. It is possible to realize a very comfortable indoor environment.

  In the water server 1, the air purifier 5 is arranged in a region below the cold water tank 14 and the hot water tank 15 and above the compressor 21 in the space in the housing 2. Therefore, it is possible to secure a drop of drinking water for moving drinking water from the cold water tank 14 and the hot water tank 15 to the cold water faucet 3 and the hot water faucet 4 while accommodating the air purifier 5 inside the housing 2. It has become.

  By the way, the air inlet 35 and the air outlet 36 of the air purifier 5 are provided so that the air inlet 35 opens on the rear surface side of the housing 2 and the air outlet 36 opens on the front surface side of the housing 2. In this case, the air suction port 35 is located on the same side as the rear surface side of the housing 2 where the heat exchanger 22 (serpentine tube) is located. Therefore, the air suction port 35 moves toward the air suction port 35. The dust contained in the air that adheres to the heat exchanger 22, and the attached dust may reduce the heat exchange efficiency of the heat exchanger 22.

  On the other hand, the water server 1 described above is provided with the air inlet 35 and the air outlet 36 of the air purifier 5 opened to the front side of the housing 2. Thereby, since the air inlet 35 is located on the opposite side (front side of the casing 2) to the rear surface side of the casing 2 where the heat exchanger 22 (serpentine tube) is located, the air inlet 35 moves toward the air inlet 35. Thus, it is possible to prevent the dust contained in the air from adhering to the heat exchanger 22 and to prevent the heat exchange efficiency of the heat exchanger 22 from being lowered due to the adhesion of dust.

  The filter 37 can be assembled in a direction orthogonal to the front-rear direction of the housing 2. However, in this case, it is difficult to secure the area of the filter 37 and it is difficult to secure the air purification function.

  On the other hand, the water server 1 is assembled with the filter 37 in a direction crossing the left-right direction of the housing 2, the upstream side air passage 38 communicating between the air suction port 35 and the filter 37, the filter 37 and the air Since the layout provided with the downstream side air passage 39 communicating between the air outlets 36 is adopted, the area of the filter 37 can be easily secured, and the air purification function can be secured.

  Moreover, since the water server 1 can remove the air cleaner 5 from the housing 2, the air cleaner 5 can be easily cleaned and maintained.

  In the above embodiment, the water server 1 of the type that introduces drinking water from the replaceable raw water container 12 to the cold water tank 14 has been described as an example. However, the present invention is applied to the cold water tank 14 from the water supply via the water purification filter. The present invention can also be applied to a water server of a type that introduces drinking water.
