Hereinafter, with reference to the accompanying drawings will be described a specific content for practicing the present invention through an embodiment of the present invention.

Although not shown in the drawings, the present invention relates to a water purifier, and an embodiment of the present invention basically includes a configuration having a general water purifier. That is, it is provided with the main body which forms an external appearance, and the filter which is provided in the center of a main body, and refine | purifies the raw water which flows in into a main body. Furthermore, in some cases, a reservoir for storing the water filtered from the filter may be provided. In addition, it may be configured to have a cold water function, in this case, a cold water unit including a cooling system for generating cold water by cooling the water from the reservoir, and protrudes to the outside of the main body to take in cold water and hot water It may be configured to include hot water collecting cock and cold water collecting cock. Each of the above components is interconnected by a hose for forming a channel, a wiring for control, and the like. However, the components generally used in water purifiers and the like of the above components are not shown in detail, and detailed description thereof will be omitted.

Referring to Figure 2, the water purifier of the present invention, forming a receiving space 115 therein, the vacuum vessel 100 to form a heat insulating vacuum portion 114 by the inner wall 120 and the outer wall 110, and the A cover 130 for sealing the opening 102 formed in the lower portion of the vacuum vessel, an inlet tube 140 extending through the cover to the receiving space, and penetrates the upper surface of the vacuum vessel to the receiving space. It comprises an elongated outlet pipe 150, and an air vent pipe 160 for discharging the steam in the vacuum vessel.

The vacuum container 100 is provided with an opening 102 at the bottom, forming an accommodation space 115 therein, and is formed a heat insulating vacuum 114 to form a vacuum around. That is, it is similar to the shape which turned over a vacuum bottle.

The adiabatic vacuum part 114 refers to a space surrounded by the inner wall 120 and the outer wall 110 forming the vacuum container, the vacuum between the inner wall and the outer wall. End portions of the inner wall and the outer wall are in close contact with each other to maintain a vacuum.

The accommodation space 115 forms a space in which hot water is stored, and a lower portion thereof is connected to the opening. The opening 102 is a hole formed in the lower portion of the vacuum container 100 and is sealed by the cover 130. The opening forms a space for the purified water to be accommodated in the accommodating space inside the vacuum vessel and a space for the various devices to enter the vacuum vessel.

On the other hand, the heat insulating vacuum section 114 may be equipped with a getter 101 provided between the inner wall and the outer wall to maintain the vacuum of the vacuum vessel. The getter 101 absorbs the gas generated in the adiabatic vacuum and maintains the vacuum. Since the heat transfer blocking of the vacuum vessel depends on the vacuum degree of the vacuum part, a getter is used in most vacuum vessels.

The cover 130 may be formed to fit the shape of the opening 102 to seal the lower portion of the vacuum vessel, and may be detachably attached or attached to the lower portion of the vacuum vessel so as not to be detached. In more detail, the cover may be coupled to the bottom of the vacuum container in various ways. For example, curling, flange bonding, welding, bolting, and the like may be various. However, the combination of the vacuum container and the cover does not affect the present invention because it is not related to the technical idea of the present invention.

The cover 130 is provided with various devices. Since it is difficult to mount the devices in the vacuum part in the vacuum container to maintain the vacuum, they can be mounted on the vacuum container provided in the cover coupled to the vacuum container. Such devices may include an inlet tube 140, an air vent tube 160, a heater 170, a thermostat 175, a thermostat, a drain tube 180, a temperature sensor 190, and the like.

The inlet pipe 140 transmits an external purified water to the receiving space 115 inside the vacuum container to accommodate the purified water in the vacuum container. The vacuum vessel generally functions as a hot water tank (hot water tank). Therefore, by receiving the external purified water through a filter or the like to heat the purified water through a heater or the like to generate and store hot water.

In this case, the water purifier may be divided into a direct equation and a low equation according to a method of accepting an external integer. Direct water refers to a method of receiving water outside the water purifier as a water purifier, purifying it through a filter, etc., and then directly sending it to a cold water tank or a hot water tank so that the water can be taken out after storage. Water storage refers to a method of receiving water outside the water purifier as a water purifier, purifying it through a filter, etc., storing it in a water storage tank, and supplying it to a cold water tank or a hot water tank as needed.

The inlet pipe 140 is supplied directly into the vacuum vessel by receiving a purified water passed directly through the filter in the case of direct water, and supplied to the inside of the vacuum vessel by receiving purified water from the water storage tank.

The heater 170 functions to generate hot water by heating the purified water supplied into the vacuum vessel by the inlet pipe. Therefore, the cover 130 is mounted on the cover 130 so as to be exposed to the accommodation space 115, and the purified water is heated by receiving power from an external power source. In FIG. 2, the heater is formed in a '∩' shape, but the heater for heating the purified water generally corresponds to a known technique, and various shapes may be used. For example, the coil may be wound in a coil shape in the accommodation space.

The temperature sensor 190 is a device such as a thermocouple (thermocouple), is mounted to penetrate the cover 130, it can measure the temperature of the purified water heated in the receiving space (115).

The thermostat (175, thermostat) refers to a device for automatically adjusting the temperature by detecting the temperature of the enclosed space, and is connected to the temperature sensor and the heater to automatically adjust the temperature of the hot water stored in the vacuum vessel to the required level. Adjust with As shown schematically in FIG. 2, the thermostat 175 is coupled to the lower portion of the cover 130 and is electrically connected to the heater and the temperature sensor.

The air vent pipe 160 forms a path to discharge the steam generated in the vacuum container to the outside of the container. The purified water stored in the vacuum vessel is heated by the heater 170 to hot water. Here, steam is generated while the purified water is heated. When steam is generated in the enclosed space, the steam pressure is increased because the volume of the steam is large, thereby preventing the inflow of purified water through the inlet pipe 140. Therefore, in order to smoothly flow the purified water should be discharged, the passage through which the steam is discharged is the air vent pipe (160)

The drain pipe 180 is for discharging or discharging the hot water stored in the vacuum vessel without being normally taken out through a takeout cock or the like, and is provided through the cover.

Meanwhile, in the present invention, hot water stored in the receiving space inside the vacuum container is discharged to the outside of the vacuum container through the water outlet pipe 150. Referring to FIG. 2, the discharge pipe 150 is formed to extend through the upper surface of the vacuum vessel to the accommodation space 115.

The outlet pipe 150 is not mounted to the cover, unlike the inlet pipe 140, is provided on the upper portion of the vacuum vessel. In general, hot water tries to rise and cold water tries to descend so that the water in the container varies with temperature. Based on the water having a boiling point of 100 ° C, the temperature of the upper side of the vacuum vessel is approximately 75 ° C, the temperature of the middle part of the vacuum vessel is about 30-40 ° C, and the bottom temperature of the vacuum chamber close to the heater. Shows a temperature distribution of about 50 ℃. Therefore, the temperature range of the hot water desired by the user is distributed on the upper side of the vacuum vessel. That is, when the outlet pipe is provided in the cover, because the outlet pipe must be extended from the bottom to the top, there is a problem such as the length of the tube or heat loss. However, in the present invention, since the outlet pipe is placed on the upper portion of the vacuum vessel in which the temperature range of hot water desired by the user is distributed, the length of the tube does not have to be long, heat loss is reduced, and the structure is simplified. Furthermore, the outlet pipe is not provided on the cover but is provided on the upper side of the vacuum container, thereby eliminating the situation where the devices are concentrated on the cover, and penetrating to the upper side of the vacuum container without forming a through hole in the cover where leakage may occur. To reduce the risk of leakage, to facilitate assembly and repair, and to take out the high temperature purified water continuously and efficiently in consideration of the temperature distribution of water in the container.

On the other hand, with respect to the extent to which the outlet pipe 150 is extended to the receiving space 115, described in more detail with reference to Figure 2, the inlet 151 of the outlet pipe from the lower inner wall (120a) of the vacuum vessel The height H1 to is configured to be smaller than the height H2 from the lower inner wall 120a of the vacuum vessel to the inlet 161 of the air vent pipe. The inlet 161 of the air vent pipe is located higher than the inlet 151 of the outlet pipe.

In Figure 2 the inner height (Hv) of the vacuum vessel is at least greater than the height (H1) to the inlet of the outlet pipe. In particular, the height H1 from the lower inner wall of the vacuum vessel to the inlet of the discharge pipe may be configured to be 0.8 times or more and 0.9 times or less of the height Hv from the lower inner wall of the vacuum vessel to the upper inner wall. have.

For example, when the height Hv inside the tank is 200 mm, the height H1 up to the inlet of the outlet pipe may be designed to a vacuum vessel of 180mm or more and 190mm or less. Here, preferably, the height H2 to the inlet of the air vent pipe may be mounted to be larger than 195 mm and smaller than 200 mm when the air vent pipe starts inside the vacuum vessel, which will be described later. In case of starting from the outlet pipe outside the container, it may be over 200mm.

This is because the steam is less dense than the water, the water rises and the water descends so that the steam outlet is high and the water outlet is low. Accordingly, the present invention provides an effect capable of continuously and efficiently extracting high temperature purified water in consideration of the temperature distribution of water in the container.

Meanwhile, as an embodiment of the present invention, Figure 3 shows a form applied to a direct type water purifier. 3 is a schematic view showing an embodiment to which the vacuum container of the present invention is applied in a direct type water purifier.

In FIG. 3, the air vent pipe 160 extends through the cover 130 to the accommodation space. At this time, the water purifier of the present invention further includes a sump container 210 provided on the outside of the vacuum container.

The sump container 210 is configured to store and discharge the purified water discharged in addition to the takeout cock. If water or steam is discharged from an airtight container, a space that can be accepted under atmospheric pressure is required. However, in the direct type water purifier, since the water storage tank is not provided separately, the water collecting tank 210 is required as a place for storing water under atmospheric pressure.

In Figure 3, the sump 210 is connected to the drain pipe 180 to receive the purified water discharged from the vacuum vessel. In addition, the outlet 162 of the air vent pipe is connected to the sump 210, is configured so that the discharged steam is condensed and stored in the sump.

On the other hand, the air vent pipe 160 may be provided inside the inlet pipe 140. That is, it is provided inside the inlet pipe 140 and penetrates the cover. However, even in this case, the air vent pipe 160 extends further upward than the outlet of the inlet pipe, and is located at an inlet 161 of the air vent pipe higher than the inlet 151 of the outlet pipe. In addition, the air vent pipe 160 penetrates from the inside of the inlet pipe to the outside in the outside of the vacuum container and is connected to the sump container 210.

 Referring to FIG. 3, raw water passed through a filter is supplied through a raw water inlet pipe 201 and distributed to a vacuum vessel 100 or a cold water tank 220 which is a hot water tank through a three-way valve 230 and 3way-valve. do. In this case, the raw water distributed to the vacuum container 100 is supplied through the inlet pipe 140, and the raw water distributed to the cold water tank is supplied through the cold water tank inlet pipe 202. The purified water supplied to the cold water tank 220 is cooled in the cold water tank and is taken out through the cold water tank discharge pipe 221.

In the case of the above configuration of the present embodiment, the steam discharged from the vacuum vessel through the air vent pipe is heat-exchanged with the purified water introduced into the vacuum vessel through the inlet pipe. That is, the air vent pipe is provided inside the inlet pipe and penetrates the cover, thereby having a structure such as a double pipe. Therefore, the exhaust steam and the inlet purified water flowing in opposite directions are heat exchanged because the mutual temperatures are different.

In the aspect of the above configuration of the present invention, in a direct-type water purifier that generates hot water by directly supplying water to the hot water tank without having a separate reservoir, heat exchange between the steam discharged through the air vent and the purified water obtained To reduce power consumption. In addition, it is possible to efficiently discharge the steam in the container to continuously take out the high temperature purified water.

On the other hand, Figure 4 shows an embodiment in which the vacuum vessel of the present invention is applied to a low water purifier. In Figure 4, the air vent pipe 160 is configured to extend through the cover 130 to the receiving space 115. In this case, the water purifier of the present embodiment further includes a reservoir 240 provided outside the vacuum container.

The reservoir 240 is a place to temporarily store the purified water in order to sufficiently maintain the flow rate of the water purifier. In the case of water purifiers, it is difficult to supply sufficient purified water when necessary unless sufficient flow rate is secured through the stored purified water, and in the case of having a cold / cold water purification function, power consumption may be excessively required because of rapid cooling or heating. Therefore, a sufficient flow rate is secured in advance through such a reservoir. In addition, when water or steam is discharged from the sealed container, a space that can be accepted under atmospheric pressure is required. In the low water purifier as shown in FIG. 4, the water reservoir 240 is used as a place for storing water under atmospheric pressure.

In FIG. 4, the outlet 162 of the air vent pipe is connected to the upper portion 242 of the reservoir, so that the discharged steam is condensed and stored in the reservoir.

On the other hand, the air vent pipe 160 may be provided inside the inlet pipe 140. That is, it is provided inside the inlet pipe 140 and penetrates the cover. However, even in this case, the air vent pipe 160 extends further upward than the outlet of the inlet pipe, and is located at an inlet 161 of the air vent pipe higher than the inlet 151 of the outlet pipe. In addition, the air vent pipe 160 penetrates from the inside of the inlet pipe to the outside in the outside of the vacuum vessel and is connected to the reservoir 210. In this case, the inlet pipe is connected to the lower portion 241 of the reservoir.

 Referring to FIG. 4, raw water that has passed through a filter is supplied to the water storage tank 240 through the raw water inlet pipe 201, and is distributed to the vacuum vessel 100 or the cold water tank 220, which is a hot water tank. In this case, the purified water distributed to the vacuum container 100 is supplied through the inlet pipe 140, and the raw water distributed to the cold water tank is supplied through the cold water tank inlet pipe 202. The purified water supplied to the cold water tank 220 is cooled in the cold water tank and is taken out through the cold water tank discharge pipe 221.

In the case of the above configuration of the present embodiment, the steam discharged from the vacuum vessel through the air vent pipe is heat-exchanged with the purified water introduced into the vacuum vessel through the inlet pipe. That is, the air vent pipe is provided inside the inlet pipe and penetrates the cover, thereby having a structure such as a double pipe. Therefore, the exhaust steam and the inlet purified water flowing in opposite directions are heat exchanged because the mutual temperatures are different.

In the aspect of the above configuration of the present invention, in the water purifier having a separate reservoir in the water purifier to supply the purified water stored in the reservoir to the hot water tank to generate hot water, the steam discharged through the air vent and the purified water obtained Heat exchange with to reduce power consumption. In addition, it is possible to efficiently discharge the steam in the container to continuously take out the high temperature purified water.

On the other hand, Figure 5 shows another embodiment of the vacuum vessel of the present invention that can be applied to a direct or low water purifier. In FIG. 5, the water purifier of the present invention may be configured such that the air vent pipe 160 branches above the water outlet pipe inlet 151 in the water outlet pipe 150.

In this case, the water purifier of the present embodiment may further include a sump provided on the outside of the vacuum container so that the water purifier may be used in a direct type water purifier, or may be used in a low water purifier to further include a reservoir.

When used in a direct water purifier, the outlet 162 of the air vent pipe is connected to a sump, and when used in a water purifier, the outlet 162 of the air vent pipe is connected to a reservoir.

On the other hand, the portion of the outlet pipe 150 extending through the upper portion of the vacuum container to the outside is wrapped with a heat insulating material. Thus, heat loss is prevented.

The side of the configuration as described above of the present embodiment, the inlet 161 of the air vent pipe to the outside of the vacuum vessel can prevent the hot water to flow out of the air vent pipe. Furthermore, the inlet of the air vent pipe is at least higher than the inlet of the outlet pipe.

The aspect of the above configuration of the present embodiment, in consideration of the temperature distribution of the water in the container to be able to continuously and efficiently take out the high temperature purified water, it is possible to discharge the steam in the container efficiently to continuously take out the high temperature purified water Make sure

On the other hand, the end shape of the inflow pipe used for the water purifier vacuum container of this invention can be improved more efficiently. This is because the hot water is going to rise and the cold water is going to fall so that the water in the container varies according to the temperature, so that the purified water is evenly distributed so that the heating can be performed more efficiently.

This configuration is shown in FIG. In FIG. 6, the inlet pipe 140 has an end 141 located inside the receiving space is closed, and at least two or more openings 142 are formed at the side of the inlet pipe extending along the receiving space. It can also be configured.
