Description
The present invention relates to a heating device for heating a hot water tank of a water purifier, and in particular, to shorten the heating time by using PTC, and to the heating device of the water purifier, which is energy-saving and safety is ensured because there is no heat transfer and good heat dissipation. It is about.
In general, normal temperature water generally means purified water of about 17 ° C, hot water means purified water of 40 ° C to 70 ° C, and hot water means purified water of 80 ° C to 92 ° C. Of course, such a temperature range can be determined relatively, so the temperature ranges of room temperature water, hot water and hot water can be defined differently.
In addition, the normal water heating system of a water purifier filters the room temperature water supplied from the tap water with purified water suitable for drinking water using a filter or the like, and supplies the same to the user by heating or cooling in a predetermined storage tank.
This water purification heating system is applied to a general water purifier capable of providing both cold and hot water.
At this time, the purified water heating system includes a purified water tank in which purified purified water is stored at room temperature, a cooling tank for storing cool water cooled to a constant temperature, and a hot water tank for storing hot water heated to a constant temperature. , Room temperature water is supplied to the hot water tank, the room temperature water is configured to be heated by a heater installed in the hot water tank.
Such water purification heating system can selectively supply cold water of about 4 ° C or hot water of 80 ° C to 92 ° C. Therefore, in order to supply hot water to the user, a heater installed in the hot water tank must be operated to maintain a temperature suitable for the hot water.
In this case, in order to adjust the hot water reaching the high temperature to a temperature desired by the user, for example, within a range of 80 ° C. to 92 ° C., the standby time may take from several tens of seconds to several minutes due to the characteristic of the large specific heat. Moreover, the temperature range of hot water that can be supplied to the user is also very limited.
The heater used in the prior art as described above is a common sheath heater (heater) is used, which is used to protect the heating element, the heating element located in the center of the protective tube, and the insulator charged between the protective tube and the heating element. Include.
The temperature range that can be heated as the sheath heater is limited, and the maximum temperature rise is known to be 30 ° C. when extracting 1 liter of water in a general water purifier.
As a result, the conventional water heating system using the siege heater can provide only cold water and high temperature water, thereby narrowing the user's choice, and increasing the time for heating with high temperature water or the temperature control time in a high temperature state. have.
In addition, in order to provide hot water, it is necessary to maintain a high temperature of hot water at all times, so unnecessary energy is consumed, and a tank for storing hot water must be manufactured and installed inside the water purifier. As the production cost is increased by using the same, the price competitiveness of the water purifier is weakened.
In addition, since the water purifier released without the conventional hot water tank provided inside does not provide hot water, a heating device capable of supplying the drinker after heating the hot water discharged instantaneously by connecting to the water purifier was needed.
It is an object of the present invention to provide a water purifier in which a heating tank for receiving purified water and a heating means for applying heat to the heating tank are PTC heaters.
The present invention provides a filter for water purification and the main body is provided with a receiving space of the cold water tank and hot water tank for cooling or heating and storing the water purified by the filter therein; A case coupled to the main body to form at least a front exterior of the main body; Extraction means for selective extraction of water contained in the cold water tank and the hot water tank; And a take-out part through which water at a temperature selected by the take-out means is taken out, wherein the hot water tank includes a heating bath in which purified water is received and a PTC heater mounted inside the heating bath. It features.
In the water purifier according to the present invention, a heating bath for providing hot water and a heating member for heating purified water mounted thereon are provided as a PTC heater, thereby improving thermal efficiency by heating water purified directly with the PTC heater. Has
In addition, the outer surface of the PTC heater has an advantage that it can solve the problems such as the scale (scale) generated in the direct heating method using an existing sheath heater by anodizing coating treatment.
In addition, the PTC heater has an advantage that even when there is no water in the heating bath, the maximum temperature does not exceed 250 ° C to ensure safety from fire due to overheating.

Looking at this, the water purifier is connected to the water supply to the general household, and is provided with a water purification system for purifying tap water supplied from the tap water.
Looking at the water purification system, one or more water filters are provided inside the water purifier. And it is provided with a cold water tank for storing the purified water from the filter.
The cold water tank is connected to a cold water cock from which cold water is taken out, and a hot water cock from which heated hot water is taken out.
Non-purified tap water supplied from the tap water is subjected to a water purification process while passing through one or more water filters provided in the water purifier.
The purified water is stored in the cold water tank through a connecting pipe. When the water stored in this way reaches a certain level, by operating the stop valve provided in the cold water tank, the water purification process is stopped.
The purified water stored in the cold water tank is divided into cold water and hot water according to the user's needs, and is taken out and drinking.
The stored purified water of the cold water tank is used as cold water and hot water according to the needs of the user. At this time, when the user needs hot water, the purified water stored in the cold water tank is moved to the hot water tank and stored, and the water stored in the hot water tank is heated to a predetermined temperature by using a heating device and then externally heated through the hot water cock.
