Description

Water-cooled water heater

The present invention relates to a domestic water bath, and more particularly, to a water-cooled water bath in which a steam condensation part of an upper portion of a cooling tower separately installed outside a heating vessel is cooled by using cooling water to rapidly condense and collect steam collected in the steam condensation part. It is about.

In general, the home bath is placed in a heating container made of a material such as glass and placed in a filter formed with a plurality of through holes, and put water and food, respectively, and heated by electricity to heat the food such as herbal medicine or tea. On the other hand, the steam generated when cooking food using such a domestic water bath contains a large amount of nutrients of the food, when the steam is released to the outside of the water bath is a significant loss of nutrients. Therefore, a steam condenser is additionally installed in the upper water bath of the upper model so that steam generated during cooking is collected and then condensed and returned to the heating vessel.

As shown in Figure 1 and 2, the conventional home water heater in the main body 12 with an electric component (not shown), such as a heater therein, and detachably seated on the upper side of the main body 12, glass A heating vessel 14 consisting of a heating vessel 14, a handle 16 disposed outside the heating vessel 14, a filter 18 seated inside the heating vessel 14, and an upper side of the heating vessel 14. It is provided with a steam condenser 19 to facilitate the collection, condensation, return of steam generated during cooking.

On the other hand, when the herbal medicine or tea is decanted using the home water heater having such a configuration, the condensation rate of the steam collected in the steam condenser 19 is inversely proportional to the internal and external temperatures of the steam condenser 19. That is, the lower the internal and external temperature of the steam condenser 19, the faster the vapor condenses. However, the conventional domestic water bath having the configuration as described above is produced without considering the speed of the steam condensation operation proceeds in the steam condenser 19, so the rate of steam condensation and return is relatively slow. Therefore, only a part of the steam generated when the medicine and the like for a long time is liquefied and returned, not a small amount of steam is liquefied and returned to the outside of the bath without being liquefied and returned properly, resulting in a significant loss of nutrients In addition to the food, depending on the food may emit a strong odor that is unpleasant to the user.

The present invention has been made to solve the problems described above, the object is to cool the steam condensation of the upper portion of the cooling tower separately installed outside the heating vessel by using the cooling water to quickly condense the steam trapped inside the steam condensation portion to recover It is to provide a water-cooled water heater.

The water-cooled water bath of the present invention for achieving the above object is configured as follows. That is, in the water bath to collect and liquefy the vapor generated from the heating vessel during cooking, it is installed separately from the heating vessel, to collect and condense the steam introduced through a predetermined connection pipe connected to the heating vessel on the top A cooling tower having a steam condensation unit, a storage tank for storing coolant for cooling the steam condensation unit, a cooling water pipe for guiding the cooling water of the storage tank to circulate into and out of the steam condensation unit, and an open end of one side of the cooling water pipe It is characterized by consisting of a pressurized pump for forcibly injecting the coolant, and pressurized so that the injected coolant can move on the cooling water pipe.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the water-cooled bath in accordance with a preferred embodiment of the present invention.

3 is an exploded perspective view of the water-cooled water heater according to the present invention, and FIG. 4 is a side cross-sectional view schematically illustrating the water-cooled water heater of FIG. 3. As shown in Figures 3 and 4, the water-cooled water bath of the present invention is a heating vessel 120, the steam is generated from the heating vessel 120 is seated on the filter 122 containing the food, such as medicines, tea, etc. Steam condensation unit 130 to collect, the connection tube 140 connecting the heating vessel 120 and the steam condensation unit 130, the cooling tower 150 for supporting the steam condensation unit 130, steam condensation unit The storage tank 160 for storing the cooling water for cooling the 130 and the cooling water pipe 162 for guiding the water in the storage tank 160 to circulate into and out of the vapor condensation unit 130 are roughly divided.

In other words, the above-described heating vessel 120 is configured to be seated on the upper side of the main body 110, the predetermined amount of water inside the filter 122 containing the medicine is placed in the heating vessel 120. After storage, the heater (not shown) of the main body 110 is boiled for a predetermined time.

On the other hand, the cooling tower 150 provided in the water-cooled water bath having the configuration as described above is installed upright side by side with the heating vessel 120 in a state supported by one side end of the main body 110, the interior is formed with a cooling water pipe 162 is convenient to house. In addition, the steam condensation unit 130 seated on the upper side of the cooling tower 150 is configured by the upper case 132 and the lower case 134 are formed to be mutually connected, and the bottom of the lower case 134 is formed to be inclined at a predetermined angle to form steam. The condensation water in the condensation unit 130 allows the condensation water to easily flow into the heating vessel 120 through the thermal conduit tube 140.

In addition, the cooling water for cooling the steam condensation unit 130 is stored in the storage tank 160 installed to be supported on one side of the cooling tower 150, and the steam condensation is carried out from the storage tank 160 via the space part inside the cooling tower 150. The cooling water pipe 162 installed to reach the inner upper side of the unit 130 guides the cooling water of the storage tank 160 to be circulated into and out of the vapor condensation unit 130. At this time, the two open ends 162a and 162b of the coolant pipe 162 are positioned inside the water storage tank 160, and the coolant forced into the open end 162a of the coolant pipe 162 opens the coolant pipe 162. After circulation, the water is discharged through the other open end 162b of the cooling water pipe 162 to be recovered into the water storage tank 160. In addition, the cooling water pipe 162 located in the steam condensation unit 130 once stands up in the longitudinal direction of the steam condensation unit 130 to reach a predetermined point on the upper side and spirally wound down from the peak to the vicinity of the cooling tower 150. It is preferable to form so that. The cooling water introduced into the spiral cooling water pipe 162 reaches a predetermined point on the inside of the steam condensation unit 130 along the upright pipe, and then drops while rotating several times along the spiral pipe. Therefore, the time that the cooling water stays inside the steam condensation part 130 is extended, and thus the cooling effect is also improved.

On the other hand, the pressure pump 164 installed on one side of the water storage tank 160 forcibly injects cooling water into one open end 162a of the cooling water pipe 162, and the injected cooling water facilitates the inside of the steam condensation unit 130. After the circulation is continuously pressurized to be discharged through the other open end (162b) of the cooling water pipe (162). As such, the cooling water discharged after circulating the inside of the steam condensation unit 130 by the pressing force of the pressure pump 164 is heated by heat taken from the high temperature steam trapped in the steam condensation unit 130. In the case of re-injection into the cooling water pipe 162, since a large cooling effect cannot be expected, it is necessary to lower the temperature of the cooling water. To this end, a cooling fan 166 is installed at one side of the storage tank 160 to blow cold air to the high temperature cooling water, and a heat sink 168 rotated by a drop of cooling water below the open end 162b through which the cooling water is discharged. Install to cool the coolant. In addition, it is preferable to adjust the amount of cooling water flowing into the pressure pump 164 through the blocking film 169 formed through the hole between the falling point of the cooling water and the pressure pump 164.

Referring to the operation of the water-cooled water bath of the present invention configured as described above in detail as follows. 3 and 4, the appropriate amount of water is stored in the inside of the heating vessel 120, and the medicine or tea to be attached to the filter 122 is placed in the heating vessel 120. As such, when the heating container 120 is placed on the main body 110 in the state in which the filter 122 is seated, the food contained in the filter 122 is added while boiling water. In this case, the steam generated while the water in the heating vessel 120 starts to boil is moved in the connection pipe 140 and collected into the steam condensation unit 130 seated on the cooling tower 160. As such, when the pressure pump 164 is operated by operating an operation switch (not shown) installed at one side of the main body 110 to liquefy and return the steam collected in the steam condensation unit 130, the water storage tank 160 is inside. The cooling water is forced into the open end 162a of the cooling water pipe 162 located at the upper portion of the cooling water pipe 162a. The cooling water forcedly introduced as described above is moved upward through the pipe using the pressing force of the pressure pump 164, and enters the vapor condensation unit 130 through the space part inside the cooling tower 150. As such, the coolant entering the steam condensation unit 130 reaches a predetermined point above the steam condensation unit 130 along the upright tube, and then rotates along the spirally formed tube from the vertex to the vicinity of the cooling tower 150. Fall down. In this process, since the coolant takes heat from the high temperature steam trapped inside the steam condensing unit 130 and warms it, thereby lowering the temperature of the steam, the steam trapped in the steam condensing unit 130 condenses more quickly.

The high temperature cooling water discharged through the other open end 162b of the cooling water pipe 162 after the inside of the steam condensation unit 130 is reached in the heat sink 169 installed at the drop point, and the cooling fan ( 166) meets the cold air blown by. Therefore, the cooling water is cooled to a low temperature again, flows into the pressure pump 164 through the through hole formed in the lower side of the blocking film 169 and is re-injected into one open end 162a of the cooling water pipe 162.

As described above, the water-cooled water bath of the present invention is installed so as to install a water storage tank for storing the cooling water for cooling the steam condensation unit at the upper part of the cooling tower separately installed outside the heating vessel, and from the water tank to the inside of the steam condensation unit through the cooling tower. The cooling water is circulated through and into the steam condensate to cool the steam condensate.

Therefore, as the steam condensation part is rapidly cooled, the steam containing a large amount of nutrients in the food is also rapidly cooled and condensed to be returned, thereby minimizing the amount of steam flowing out of the water bath to the minimum to effectively prevent the loss of nutrients in the food. Depending on the type, it is possible to suppress the emission of a strong odor that may cause discomfort to the user.
