{DRINKING WATER SUPPLYING DEVICE}

(Cross reference of related application)

This international application claims priority to Japanese Patent Application No. 2014-127992, filed on June 23, 2014, with reference to the entire contents of Japanese Patent Application No. 2014-127992 It shall be used in this international application.

The present invention relates to a beverage supply apparatus, and more particularly, to a beverage supply apparatus that supplies raw water supplied from a replaceable water supply tank as a beverage with improved water quality.

For example, as shown in Patent Documents 1 and 2, a cold water tank is disposed in an upper portion of the inside of a water cooler main body, the inside of the cold water tank is divided into a low water portion and a cold water portion by a separating member, A cartridge in which activated carbon is wrapped in a nonwoven fabric and accommodated, for example, is provided on the lower surface of the member, and the cartridge is used to filter the tap water to supply it as drinking water.

However, in the conventional art, since water is forced to pass through the water quality improving material (by passing water through the water quality improvement material) by the water pressure from the upstream side, the water passes through the water quality improvement material Or in the extreme case, a specific water channel is generated in the water quality improving material, and the water is passed through only the water, and the water quality improving effect is extremely reduced.

Japanese Patent Application Laid-Open No. H05-149663 WO2007 / 094364

In the conventional beverage supply device, it has been required to sufficiently secure the time for the raw water to contact the water quality improvement material in order to improve the water quality by the water quality improvement material.

Therefore, it is desirable to provide a beverage supply apparatus capable of achieving sufficient water quality improvement.

In the first aspect of the present invention, there is provided a beverage supply apparatus comprising: a raw water supply section; a water quality improvement section provided downstream of the raw water supply section and containing at least one water quality improvement material; And a water supply portion for discharging the water stored in the fresh water storage portion as drinking water, wherein the water quality improvement portion includes a water quality improvement portion for improving water quality of the water quality improvement portion, And the upper part of the clean water reservoir are communicated with the atmosphere.

Therefore, the pressure applied to the upper portion of the at least one water quality improving material is only a predetermined water pressure corresponding to the atmospheric pressure and the water level position determined by the water level positioning portion. Further, when the full water level is set near the top of the at least one water quality improvement material, the pressure applied to the top of the at least one water quality improvement material becomes a pressure substantially determined only by the atmospheric pressure.

In addition, since the fresh water storage portion on the downstream side of the water quality improvement portion also communicates with the atmosphere, the pressure on the outlet side of the water quality improvement portion does not suddenly become negative when the water supply portion is opened. Thereby, a large pressure is not applied to the upper portion of the at least one water quality improving material, and the lower portion of the at least one water quality improving material is also sucked out with a large pressure. Therefore, the water in the water quality improving material is allowed to flow at the rate of descending by its own weight, and does not descend at the rate higher than the rate of descending.

Also, there is no problem that the effect of improving the water quality is extremely reduced by making the water pass through only the passage by making a specific water passage which is not intended by the at least one water quality improving material. Therefore, a water quality improvement part, in which a sufficient water quality improvement time is obtained, is obtained by the water speed of the water in the at least one water quality improvement material, and water quality improved water quality can always be obtained.

When the water level in the clean water storage portion rises and exceeds the lower end of the water quality improvement portion, a pressure difference of the water level exceeding the lower end is applied to the outlet side of the water quality improvement portion in addition to the atmospheric pressure, It acts only in a direction to suppress the flow rate in one of the water quality improving materials and does not increase the flow rate. Therefore, the water quality improvement effect is increased or decreased in comparison with the case where water flows naturally by the self weight in the at least one water quality improving material.

According to one aspect of the present invention, in the above water quality improvement portion, a plurality of water quality improvement materials (at least two kinds of water quality improvement materials) are disposed vertically, and a flow rate suitable for water quality improvement by the water quality improvement material It is also possible to control using the flow resistance in the disposed water quality improving material.

Generally, as a material for improving the adsorption, spouting, and antibacterial water quality, a water quality improving material made of a powder, a granule, or a pellet is known in order to increase a contact area with water. And water is brought into contact with the surface of the water quality improvement material for a predetermined period of time, whereby the water quality improvement effect is exerted. In this case, the effect of water quality improvement may vary depending on the flow rate per unit volume of the water quality improving material. In other words, by controlling the flow rate per unit amount of the water quality improving material, a desired level of water quality improving effect can be obtained.

On the other hand, the filter material of the filtration system often has an integral structure in a sheet-like shape and a solid shape, and by varying the dimensions of the other side of the area and the thickness, for example, .

Therefore, first, the desired flow rate is determined on the basis of the total amount of the water quality improving material for the former (adsorption / spouting / antibacterial water quality improving material), and for the latter (filtering material of the filtration system) So that the desired flow rate can be obtained. Therefore, the design of the water quality improvement section becomes natural and easy.

In one aspect of the present invention, a flow rate restraining member may be disposed at the bottom of the water quality improvement portion, and a flow rate appropriate for water quality improvement by the at least one water quality improvement material may be formed or adjusted using the flow rate restraining member.

A sufficient water quality improvement effect can be obtained by providing the flow rate restraining member at the bottom of the at least one water quality improvement member even if the at least one water quality improvement member alone does not provide sufficient effect of improving water quality due to too much flow rate.

In one aspect of the present invention, the water quality improvement section may be immersed in the fresh water storage section, or may be provided with a cooling section for cooling the fresh water storage section.

Even if the room temperature rises due to a change in temperature due to the season or a change in the indoor environment in which the beverage supply device is installed or the like, the at least one water quality improving material in the water quality improvement part So that the propagation of bacteria and the like on the at least one water quality improving material can be suppressed.

According to the beverage supply apparatus of the first aspect of the present invention, since the water passes through the water quality improvement material at a constant flow rate, it is possible to stably realize the improvement of the water quality.

2 is a vertical sectional view of the beverage supply apparatus.
3 is a partial cross-sectional view of the beverage supply apparatus.

The embodiments described below are merely examples, and various design modifications performed by those skilled in the art within the scope of the present invention are included in the scope of the present invention.

In Fig. 1, the beverage supply device is installed in the floor F. The housing 201 of the beverage supply device has a vertically elongated rectangular parallelepiped shape which swells forward slightly. In the front surface (the left side in Fig. 1) of the housing 201, an intermediate position in the vertical direction is concave. In the concave portion 211, known water supply cocks 175 and 170 for hot water and cold water are provided as water supply portions.

The lower surface of the recess 211 is formed by the drip tray 214 of the drinking cup. The feed cocks (175, 170) are provided with a lever body (215) which is curved and extends downward. The water supply cocks 175 and 170 are configured to be opened by pressing the lever body 215 from the front.

The top of the housing 201 is closed by a head cover 110 having a rectangular shape when viewed in plan view. The head cover 110 has a guide portion 111 formed therein. The head cover 110 has a function of supporting the bottle 120 in a state in which the liquid container 120 (hereinafter referred to as " bottle ") such as bottle water (see Fig. 2) is turned upside down. The guide portion 111 is recessed downward in one position (rear position in this embodiment) in the main direction. At the bottom of the recessed portion 118, an air communication portion 133 penetrating the bottom face in the vertical direction is provided.

As shown in Figs. 2 and 3, raw water 121 is stored inside the bottle 120. Fig. In the bottle 120, as shown in Figs. 4 and 5, the inside and outside air are blocked by a detachable liquid-supply cap 122. The liquid-supply cap 122 has a sealing valve 123. A force by the elastic member 124 acts on the sealing valve 123 so that the bottle 120 alone is in an airtight state as shown in Fig. 6 (a). As a result, the opening of the bottle 120 is blocked by the sealing valve 123. Therefore, in the state of the bottle 120 as a whole, there is no leakage of liquid.

Next, a description will be given based on Fig. 2 and Fig. The guide portion 111 has a bottle guide 112 having a shape that shifts from a mortar shape to a straight shape. On the bottom portion 113, a projection 114 on the tube and an opening 115 are formed. The guide portion 111 guides the bottle 120 in the bottle guide 112 so that the opening 115 and the liquid level cap 122 of the bottle 120 are engaged. The inside of the opening hole 115 is formed by an opening 116 which is open to the inside of the system.

When the liquid-supply cap 122 of the bottle 120 moves from the portion of the truncated cone in the guide portion 111 to the straight portion and reaches the bottom portion 113 of the bottle guide 112, The seal valve 123 attached to the liquid level cap 122 is opened and the liquid level cap 122 is opened as shown in Fig. 6 (b) . A flow path is formed between the opening 115 in the projection 114 on the tube and the bottle 120 and a flow path formed between the opening 115 and the bottle 120, Thereby constituting an example of the raw water supply unit.

The water quality improvement system will be described from an initial state. The water quality improving water 121a flowing out from the opening 116 is introduced into the inlet 131 which is the first section of the water quality improving portion and the first water quality is improved by the mesh 132 provided at the bottom of the inlet 131 .

Also, the water quality improving water 121a is subjected to the second water quality improvement with the activated carbon 137, which is the second section of the water quality improving portion. The activated carbon 137 may be in the form of powder, granule, pellet, or solid. The activated carbon 137 is covered with a water permeable package (not shown) for easy replacement, and is stored in the activated carbon storage portion 139 on the tube. A mesh 157 is provided on the bottom surface of the activated carbon accommodating portion 139 as in the first section.

Dust and microorganisms are adsorbed and collected by the mesh 132 and the activated carbon 137, and deodorization is performed. The objects to be captured by the activated carbon 137 are calcium hypochlorite, trihalomethane, organic substances, odor substances, and chlorine-based organic substances. As the activated carbon 137, fibrous activated carbon prepared by using a plant-derived natural fiber or mineral-derived synthetic fiber, or a mixture of natural fiber and synthetic fiber carbonized and prepared using a binder is preferable. The activated carbon 137 may be supplemented with biological minerals. Biological minerals can be supplied as isotonic solutions with mineral components (K, Ca, Na, Mg) in balance very close to body fluids.

Further, the water quality improving water 121a is subjected to the third water quality improvement by the hollow fiber membrane 141, which is the third section of the water quality improving section. The hollow fiber membrane 141 is formed by collecting and fixing hollow fibers. (One end of the hollow fiber membrane 141) is exposed, and the water molecules absorbed from the surface of the hollow fiber are released from the other end (the other end of the hollow fiber) of the hollow fiber. Thus, .

In this embodiment, the hollow fiber membrane 141 is set on the tube-shaped guide case 142, and the guide case 142 is provided on the lower side of the activated carbon 137 as the second section. Specifically, the guide case 142 is screwed and fixed to the threaded portion 138 of the activated carbon accommodating portion 139.

The portion indicated by reference numeral 144 is a threaded portion in the guide case 142. In the hollow fiber membrane 141 as the third section, the water quality improving water 121a passes downward at a permeation rate defined by the hollow fiber membrane 141 and falls downward and is discharged from the lower end 143 of the hollow fiber membrane 141 . And the lower end portion 143 becomes a discharge portion (discharge portion of the water quality improvement portion) which is a portion where the water with improved water quality spontaneously falls and is discharged.

As the hollow fiber membrane 141, an aggregate of fibers having a pore diameter of 0.01 to 0.09 mu m and provided with perforations on the peripheral wall of the slit is favorable.

In the water quality improvement system, the water quality improving water 121a flowing out from the opening 116 is filtered by the water quality improving material, thereby causing the flow resistance. The mesh 132, the activated carbon 137, and the hollow fiber membrane 141 correspond to examples of the water quality improving material.

Therefore, water tends to stay in the water quality improvement system. Amount of the water-quality-improving water 121a from the opening 116 >> amount of the water-quality-improving water 121a passing through the hollow fiber membrane 141 in the third section ", for example . Therefore, the water level in the water quality improvement system gradually rises, and once the water level of the water quality improvement water 121a rises to the full water level position 117, the outflow from the opening 116 is temporarily suppressed.

Specifically, when the water level in the inlet portion 131 of the water quality improvement portion rises to the full water level position 117 slightly higher than the bottom portion 113 in the bottle guide 112, the drop of water from the inside of the bottle 120 It stops automatically. And the full number positioning section defines the full number position 117 thereof. In the present embodiment, the full water level position 117 is determined by the position of the bottom portion 113 in the inlet portion 131 when the water quality improving portion is engaged at the engaging portion 136, do.

The purified water 121b after the water quality improvement is introduced and stored in the clean water storage portion. The fresh water storage portion is open to the atmosphere through the communicating tube 154 and the communication hole 134. A filter (not shown) is provided on the upper portion (upper inlet portion) of the communicating tube 154, and the clean water storage portion communicates with the atmosphere through a filter. The filter allows the clean air to communicate with the clean water reservoir. In the clean water storage section, one region is constituted by the partition plate 151 and the upper and lower chambers. The upper chamber is the storage tank 150, and the lower chamber is the storage tank cooling chamber 155. [

The head cover 110 communicates with the atmosphere outside the housing through the communicating tube 154 and the communication hole 134 formed by a hole penetrating the housing 201. The storage tank 150 and the storage tank cooling chamber 155 of the purified water storage portion are covered with the heat insulating fixing member 130. The heat insulating fixing member 130 has a function of insulating and simultaneously fixing the storage tank 150 and the storage tank cooling chamber 155. The heat insulating fixing member 130 is formed of, for example, a heat insulating material such as foamed styrol.

For example, it is assumed that the liquid level position 152 is near the bottom of the storage tank cooling chamber 155, and the liquid level position 152 is gradually raised. The state in which the water quality improving water 121a falls from the hollow fiber membrane 141 as the third section as the purified water 121b in the storage tank 150 is defined as the pattern 1 (atmospheric release) The state is determined by the relationship of forces.

The liquid level position 152 continues to increase as the time elapses, while the pressure of the water level difference of the overflow level is applied to the outlet side of the water quality improvement portion in addition to the atmospheric pressure, 150 and is balanced at the time when the purified water 121b rises to the full water level position 117 and the outflow of the purified water 121b from the opening 116 stops. The state in which the hollow fiber membrane 141 as the third section flows into the clean water 121b of the storage tank 150 is defined as a pattern 2 (underwater release).

The hot water tank 160 is further provided below the clean water storage portion. A clean water inlet 156 for introducing the purified water 121b is provided in the vicinity of the partition plate 151 and a supply pipe 153 is provided so that the liquid above the storage tank cooling chamber 155 can be introduced. The lower end of the supply pipe 153 is close to the lower portion 161 of the hot water tank 160.

A hot water supply pipe 163 (not shown in some drawings) is connected to the upper portion 162 of the hot water tank 160 for hot water discharge. The hot water supply pipe 163 is also connected to the hot water cock 175. In the state of Fig. 3, the hot water cock 175 is closed, and the clean water 121b can hardly flow into the hot water tank 160 filled with air.

The purified water 121b of the storage tank 150 flows into the hot water tank 160 through the supply pipe 153 to fill the hot water tank 160. [ The liquid level position 152 at the full water level position 117 of the storage tank 150 is temporarily lowered temporarily because the purified water 121b is supplied to the volume of the hot water tank 160. [ Therefore, until the balance is broken and the clean water 121b flows out again from the opening portion 116 and the liquid surface position 152 returns to the full water level position 117 along the pattern 1 and the pattern 2 described above Continue.

A heating unit and a heating control unit not shown are provided in the hot water tank 160 and the purified water 121b of the hot water tank 160 is maintained at a desired temperature by the heating unit and the heating control unit.

On the other hand, the purified water 121b accumulated in the storage tank cooling chamber 155 becomes the desired temperature cold water by the refrigerator 167 provided below the main body. The refrigerant transfer tube is extended from the freezer 167 and the cooling medium transfer tube is wound around the outer periphery of the storage tank cooling chamber 155 to form the cooling part 169. The purified water 121b accumulated in the storage tank cooling chamber 155 is cooled through the cooling section 169. [ The refrigerator 167 is controlled by a sensor (not shown) mounted on the storage tank cooling chamber 155 and a temperature control unit (not shown).

The use state of the cold / hot water will be described. The bottom of the storage tank cooling chamber 155 and the cold water cock 170 are connected by a cold water supply pipe (not shown). In order to discharge cold water stored at a desired temperature, the cold water cock 170 is opened.

The cold water cock 170 is opened from the bottom of the storage tank cooling chamber 155 through a cold water discharge pipe (not shown) by the water head difference between the full water level position 117 and the position (height) The cooled purified water 121b is supplied from the cold water cock 170.

On the other hand, the discharge of hot water is as follows. More specifically, since the hot water supply pipe 163 (not shown) is connected to the hot water tank 175 from the hot water tank 160, when the hot water cock 175 is opened, the full water level position 117 and the hot water cock 175 The purified water 121b which has become hot water is supplied from the hot water cock 175 by the water head difference between the position (specifically, the height and the height of the cold water cock).

At this time, purified water 121b of the same amount as the supplied hot water is supplemented from the storage tank 150 to the hot water tank 160 through the supply pipe 153. The reason why the supply pipe 153 is disposed at the bottom and the hot water supply pipe 163 is disposed at the upper portion in the hot water tank 160 is that, It is preferable to set the lower part of the container and the upper part of the container to the upper part.

The water level positioning unit formed in the raw water introduction portion of the water quality improvement unit can be configured to detect the water level in the upper portion of the water quality improvement material by using a water level sensor such as an optical type or float type. It is also possible to provide a solenoid valve in the flow path of the raw water supply portion and close the solenoid valve at a predetermined full position by a signal from the water level sensor.

As another embodiment of the raw water supply portion, it is possible to use, as a tank, a soft tank which contracts according to the amount of raw water used. Alternatively, as the tank, a tank-shaped tank in which a raw water supply portion is provided on the upper portion and an upper portion is opened to the atmosphere may be used. In this case, a water level sensor such as an optical type or float type sensor is used as the water level positioning portion provided at the raw water introduction portion of the water quality improvement portion so that the water level of the upper portion of the water quality improvement material can be detected. It is preferable to adopt a configuration in which In this case, implementation is facilitated.
