[Previous Technical Literature] [Patent Literature]

[Patent Document 1] Japanese Patent Laid-Open No. 2011-046446

If the drinking machine is installed in a living room or a dining room, the drinking water can be used at any time, which is convenient, but the casing of the drinking machine can occupy a part of the indoor space of the living room or the restaurant. That is, the space occupied by the drinker is during the period of unused drinking water. Becomes useless invalid space.

Here, the inventor notices the possibility that if the drinking space of the drinking machine is used to purify the indoor air of the living room or the restaurant during the period in which the drinking water is not used, the drinking water can be used at any time. The air in the living room or dining room is also excellent, enabling an extremely comfortable indoor environment.

The problem to be solved by the present invention is to provide a drinking machine that can achieve an extremely comfortable indoor environment in a limited living space.

In order to solve the above problems, the present invention provides a brewing machine of the following constitution.

A drink-making machine, comprising: a casing comprising: a cylinder wall extending in an up-and-down direction; a top plate disposed to close the upper portion of the cylinder wall; and a bottom plate for closing the lower portion of the cylinder wall The method comprises: a cold water tank and a warm water tank, which are housed inside the casing; a cooling device that cools the drinking water in the cold water tank; a heating device that heats the drinking water in the warm water tank; the cold water tap and the warm water a faucet disposed on a front side of the casing; a cold water injection path communicating between the cold water tank and the cold water faucet; and a warm water injection path connecting the warm water tank and the warm water faucet; The brewing machine is characterized in that an air cleaner is housed and disposed in the casing, and the air cleaner has an air intake port for sucking air outside the casing, and filtering the air sucked from the air suction port. And discharging the air purified by the filter to an air outlet of the outside of the casing.

In this way, during the period when the drinking water is not used, the air cleaner installed in the casing of the drinker can also be used to purify the air. Therefore, by setting the drinker in the living room or restaurant In addition to the use of good drinking water, the indoor air in the living room or dining room can be improved, and an extremely comfortable indoor environment can be realized in a limited living space.

As the cooling device, there may be employed a compressor that is fixed to a bottom plate of the casing, and a heat exchanger that exchanges heat between a high-temperature refrigerant ejected from the compressor and outside air; an expansion valve And reducing the temperature by decompressing the refrigerant of the heat exchanger; and cooling the coil, which is wound around the cold water tank by heat exchange between the low temperature refrigerant passing through the expansion valve and the cold water tank Outer week. In this case, the air cleaner is preferably disposed in a space in the casing and disposed in a region below the cold water tank and the warm water tank and above the compressor.

In this way, the air cleaner can be accommodated inside the casing on the one hand, and the difference in drinking water for moving the drinking water from the cold water tank and the warm water tank to the cold water tap and the warm water tap can be ensured.

As the heat exchanger, a metal serpentine tube formed by bending a refrigerant from the upper side toward the lower side while reciprocating the refrigerant on the back surface of the casing may be employed. In this case, the air intake port and the air ejection port may be opened to the rear side of the casing by the air intake port, and the air discharge port may be opened to the front side of the casing. The mouth is located on the same side of the back side of the casing where the serpentine tube is located, so the dust contained in the air moving toward the air suction port adheres to the serpentine tube, and the heat exchange of the serpentine tube due to the adhered dust The efficiency is reduced. Therefore, it is preferable that the air suction port and the air ejection port are provided to open on the front side of the casing.

Thus, since the air suction port is located on the opposite side (the front side of the casing) on the back side of the casing where the serpentine tube is located, it is possible to prevent the dust contained in the air moving toward the air suction port from adhering to the serpentine tube. And it can prevent the heat exchange efficiency of the serpentine tube from being lowered due to the adhesion of dust.

In the case where the filter is a flat member, the filter may be attached in a direction orthogonal to the front and rear directions of the casing, but it is difficult to ensure the area of the filter in such a manner. It is difficult to ensure the purification function of the air. Therefore, it is preferable that the filter is installed in such a manner that the direction in which the air passes through the filter is the left-right direction of the casing so as to intersect the left-right direction of the casing, and is disposed between the air suction port and the filter. The upstream side ventilation path and the arrangement of the downstream side ventilation path between the filter and the air ejection port. In this way, the area of the filter can be easily ensured and the air purification function can be ensured.

Preferably, the air cleaner is detachable from the housing. Thus, cleaning or maintenance of the air cleaner is facilitated by removing the air cleaner from the housing.

The brewing machine of the present invention can purify the air during the period when the drinking water is not used, and also the air purifier contained in the casing of the brewing machine. Therefore, by setting the brewing machine in a living room or a dining room, in addition to being able to use the drinking water at any time, the air in the living room or restaurant can be improved, and in a limited living space. A very comfortable indoor environment.

Fig. 1 is a view showing the brewing machine of the embodiment of the present invention as seen from the front side.

Figure 2 is a cross-sectional view taken along line II-II of Figure 1.

Figure 3 is a cross-sectional view showing the vicinity of the air cleaner of the brewing machine shown in Figure 1.

Fig. 1 shows a brewing machine 1 according to an embodiment of the present invention. The drink dispenser 1 has a casing 2 disposed on the horizontal floor surface F, a cold faucet 3 disposed on the front side of the casing 2, a warm water faucet 4, and an air cleaner 5 housed in the casing 2.

As shown in Fig. 2, the casing 2 has a cylindrical wall 6 extending in the up-and-down direction, a top plate 7 provided to close the upper portion of the cylindrical wall 6, and a bottom plate 8 provided to close the lower portion of the cylindrical wall 6. The tubular wall 6 is composed of a pair of left and right side panels 9, a front panel 10 that connects the front edges of the side panels 9, and a back panel 11 that connects the rear edges of the side panels 9. The front and rear directions are viewed from the user who has poured out the drinking water from the cold water tap 3 or the warm water tap 4, and the front side is the front side. The far side is the rear.

A replacement raw water container 12 is detachably mounted to the top plate 7 of the casing 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 the case of full water. The raw water container 12 is formed to have flexibility so as to shrink with a decrease in the amount of remaining water inside. A cold water tank 14 and a warm water tank 15 are housed inside the casing 2. The top plate 7 is provided with a raw water introduction pipe 16 for introducing drinking water from the raw water container 12 into 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 fixed and 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 an end portion of the raw water introduction pipe 16 on the cold water tank 14 side. When the raw water container 12 is of a type that has a rigidity that does not deform even if the amount of remaining water inside is reduced, the float valve 17 is not required. In this case, the water level in the cold water tank 14 is the same height as the end portion of the raw water introduction pipe 16 on the cold water tank 14 side. A decorative cover 18 covering the raw water container 12 is attached to the upper portion of the casing 2.

A cooling device 20 that cools the drinking water contained in the cold water tank 14 is attached to the cold water tank 14. The cooling device 20 has a compressor 21, a heat exchanger 22, an expansion valve 23, and a cooling pipe 24. The compressor 21 is fixed to the bottom plate 8 of the casing 2. The heat exchanger 22 is a metal serpentine tube which is formed by bending along the back surface of the casing 2 so that the refrigerant reciprocates left and right while moving downward from above. The compressor 21, the heat exchanger 22, the expansion valve 23, and the cooling pipe 24 are connected by a pipe for a refrigerant so that the refrigerant can be sequentially passed through and circulated. The cooling pipe 24 is spirally wound around the outer periphery of the lower portion of the cold water tank 14.

The compressor 21 sucks the refrigerant from the cooling pipe 24, compresses the refrigerant, raises the temperature of the refrigerant, and ejects the high-temperature high-pressure refrigerant to the heat exchanger 22 side. The heat exchanger 22 receives the high-temperature and high-pressure refrigerant discharged from the compressor 21, and exchanges heat 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 passing through the expansion valve 23, and Heat exchange is performed between the refrigerant and the cold water tank 14. The compressor 21 is actuated when the temperature of the cold water tank 14 becomes higher than a certain threshold. At this time, the cooling pipe 24 is cooled at a low temperature of about 15 ° C to minus 30 ° C to cool the drinking water in the cold water tank 14 . . In this manner, the drinking water in the cold water tank 14 is maintained at a specific low temperature (about 5 ° C).

One end of the cold water discharge path 25 connecting the cold water tank 14 and the cold water tap 3 is connected to the bottom surface of the cold water tank 14, and the low temperature drinking water can be injected from the cold water tank 14 by the operation of opening the cold water tap 3 Cup and so on. Here, the cold water tap 3 is a method in which the low temperature drinking water in the cold water tank 14 is injected from the cold water tap 3 through the cold water discharge path 25 by its own weight (that is, the low temperature drinking water can be injected without using a pump). It is disposed at a lower position on the bottom surface of the cold water tank 14. The capacity of the drinking water of the cold water tank 14 is smaller than the capacity of the raw water container 12, and is about 2 to 4 liters.

The warm water tank 15 is disposed below the cold water tank 14. A heating device 26 for heating the drinking water contained in the warm water tank 15 is attached to the warm water tank 15. In the figure, an example in which a heater (sheath heater) is used for the heating device 26 is shown, but a band heater may also be used. The armor heater is attached to a metal pipe and accommodates a heating wire that generates heat by energization, and is installed so as to extend through the wall surface of the warm water tank 15 and extend into the interior of the warm water tank 15. The band heater is a cylindrical heat generating body in which a heating wire that generates heat by energization is embedded, and is attached to the outside of the warm water tank 15 to be attached. The heating device 26 maintains the drinking water in the warm water tank 15 at a high temperature (about 90 ° C).

On the upper surface of the warm water tank 15, a warm water injection path 27 connecting the warm water tank 15 and the warm water tap 4 is connected, and the high temperature drinking water can be injected from the warm water tank 15 by opening the warm water tap 4 to Cup and so on. The capacity of the warm water tank 15 is about 1 to 2 liters.

The cold water tank 14 and the warm water tank 15 communicate with each other via the tank connecting pipe 28. When the drinking water is poured from the warm water tank 15, the drinking water equivalent to the drinking water flows into the warm water tank 15 from the cold water tank 14 through the tank connecting pipe 28. The warm water tank 15 is always kept in a full water state. Here, the warm water tap 4 is caused by the high temperature drinking water in the warm water tank 15 due to the weight of the drinking water in the cold water tank 14. The pressure is discharged from the warm water tap 4 through the warm water discharge path 27 (that is, the drinking water can be injected without using a pump), and is disposed at a lower position on the bottom surface of the cold water tank 14.

As shown in FIG. 1, the housing 2 is provided with a housing opening 30 for accommodating the air cleaner 5. The accommodating opening 30 is opened to the front panel 10 of the casing 2 so that the air cleaner 5 can be attached and detached from the front side of the casing 2. The air cleaner 5 is disposed in a space inside the casing 2, and is disposed below the cold water tank 14 and the warm water tank 15 and above the compressor 21.

As shown in FIG. 3, the accommodating opening portion 30 has an inner bottom plate 31 for supporting the air cleaner 5 from the lower side, a pair of left and right inner side plates 32 from the left and right side supporting air cleaners 5, and an upper side opposite to the inner bottom plate 31. The top plate 33 is inside. The air cleaner 5 has a casing 34 having a size accommodating in the housing opening 30 of the casing 2, an air suction port 35 and an air ejection port 36 (refer to FIG. 1) which is equal to the front opening of the casing 34; 37, which is housed in the outer casing 34; an upstream side ventilation path 38 that communicates between the air suction port 35 and the filter 37; a downstream side ventilation path 39 that communicates between the filter 37 and the air ejection port 36; and a centrifugal fan 40, which is disposed in the middle of the downstream side ventilation path 39.

The filter 37 is a planar member formed of fibers in a manner of air permeability, and purifies the air by capturing the dust or fine particles in the air with the filter 37 by passing the air through the filter. The filter 37 is attached in a direction crossing the left and right direction of the casing 2 so that the direction in which the air passes through the filter 37 is the left-right direction of the casing 2. As such a planar filter 37, for example, a corrugated shape in which a sheet-like filter material is laminated in a front-rear direction or a vertical direction of the casing 2 can be employed. In the drawing, the orientation of the filter 37 is an orientation orthogonal to the left-right direction of the casing 2, but may be an orientation that obliquely intersects the left-right direction of the casing 2.

The air intake port 35 is disposed below the filter 37, and is provided with an upstream side ventilation path 38 in an L shape so as to communicate between the air suction port 35 and the filter 37. Further, the air ejection port 36 is disposed above the filter 37, and a downstream side ventilation path 39 is provided in an L shape so as to communicate between the air ejection port 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 be rotated about an axis parallel to the left-right direction of the casing 2 . When the impeller 42 rotates, the air flow passing through the filter 37 from the upstream side ventilation path 38 toward the downstream side ventilation path 39 is generated by the negative pressure generated inside the impeller 42. At this time, the air outside the casing 2 is sucked from the air suction port 35 to the inside of the outer casing 34, and the air is sequentially discharged from the air discharge port 36 through the upstream side ventilation path 38, the filter 37, and the downstream side ventilation path 39. To the outside of the outer casing 34 (outside of the casing 2).

The drinker 1 can also purify the air by the air cleaner 5 housed in the casing 2 of the brewing machine 1 while the drinking water is not being used. Therefore, by setting the brewing machine 1 indoors in a living room or a restaurant, in addition to being able to use the drinking water at any time, the air in the living room or the dining room is also improved, and can be realized in a limited living space. Extremely comfortable indoor environment.

Further, the drink dispenser 1 is disposed in a space inside the casing 2, and is disposed below the cold water tank 14 and the warm water tank 15, and an air cleaner 5 is disposed above the compressor 21. Therefore, the air cleaner 5 can be housed inside the casing 2 while ensuring the difference in drinking water for moving the drinking water from the cold water tank 14 and the warm water tank 15 to the cold water tap 3 and the warm water tap 4.

In addition, the air intake port 35 and the air discharge port 36 of the air cleaner 5 can be opened to the rear side of the casing 2 by the air suction port 35, and the air discharge port 36 is opened to the front side of the casing 2, However, since the air suction port 35 is located on the same side of the back side of the casing 2 where the heat exchanger 22 (the serpentine tube) is located, the dust contained in the air moving toward the air suction port 35 adheres to the heat exchange. The device 22 has a tendency to lower the heat exchange efficiency of the heat exchanger 22 due to the adhered dust.

On the other hand, the above-described brewing machine 1 is installed such that the air suction port 35 and the air ejection port 36 of the air cleaner 5 are opened to the front side of the casing 2. Thereby, since the air suction port 35 is located on the opposite side of the back side of the casing 2 where the heat exchanger 22 (the serpentine tube) is located (the positive of the casing 2) The surface side prevents the dust contained in the air moving toward the air suction port 35 from adhering to the heat exchanger 22, and prevents the heat exchange efficiency of the heat exchanger 22 from being lowered due to the adhesion of the dust.

The filter 37 may be attached in a direction orthogonal to the front and rear directions of the casing 2, but it is difficult to secure the area of the filter 37 in such a manner, and it is difficult to secure the air purifying function.

On the other hand, the above-described brewing machine 1 is provided with a filter 37 in a direction intersecting the left-right direction of the casing 2, and an upstream side ventilation path 38 provided between the communication air suction port 35 and the filter 37, And the arrangement of the downstream side ventilation path 39 between the communication filter 37 and the air ejection port 36, thereby easily securing the area of the filter 37 and ensuring the air purification function.

Further, since the above-described brewing machine 1 can remove the air cleaner 5 from the casing 2, it is easy to clean or maintain the air cleaner.

In the above embodiment, the drinker 1 of the type in which the drinking water is introduced into the cold water tank 14 from the replacement raw water container 12 is exemplified, but the present invention can also be applied to the introduction of drinking water from the sewer via the purified water filter. A type of open water dispenser for cold water tanks 14.
