Hereinafter, an embodiment of an electric heating apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic diagram of an electric heating apparatus according to the present invention, Figure 2 is an exploded perspective view showing a coupling structure of the distributor and the distributor heater included in the electric heating apparatus according to the present invention, Figure 3 is an electric heating according to the present invention Partial cross section of the device.

The electric heating device according to the present invention is a heating device that heats water using electricity instead of burning water by burning oil or gas, and a plurality of indoor spaces 10 are supplied through a supply pipe 200 to supply water filled therein. Distributor 100 for distributing and supplying the pipe, the distributor heater 110 for heating the water inside the distributor 100, and the water passing through the respective interior space 10 piping through the recovery pipe 400 Supply unit 500, a circulation pump 600 for pumping the water inside the recovery unit 500 to the distributor 100, and the supply water mounted on each supply pipe 200 to open and close each supply pipe 200 independently The on / off valve 300 and the controller 800 for controlling the operation of the distributor heater 110 and the supply water on / off valve 300 respectively by receiving an operation signal from the user.

In this case, the indoor space 10 refers to a space provided inside the building such as a room or a living room, and the piping refers to an indoor space 10 when hot water passes inside such as a hot water pipe embedded in the floor of the room or living room. It means hot water line heating). In this embodiment, since the electric heating device according to the present invention is described as an example of supplying hot water to the four indoor space (10) piping, the distributor 100 is configured to connect four supply pipes 200, The number of supply pipes 200 connected to the distributor 100 may be variously changed according to the number of indoor spaces 10 to which hot water is to be supplied.

On the other hand, the distributor 100 may be manufactured in any shape as long as the inner space can be formed so that a predetermined amount or more of water can be filled therein, but the inner wall is so that the filled water flows smoothly to the supply pipe 200 side The spherical shape, that is, is preferably formed in a cylindrical shape as shown in this embodiment. In addition, the distributor heater 110 includes a heater coil 112 that generates heat when an electric current is applied from the outside. When the heater 100 is mounted in the distributor 100, the heater coil 112 is drawn into the distributor 100. It is configured to be in direct contact with the water filled in the dispenser 100. At this time, when the distributor heater 110 is mounted to the distributor 100, the entire heater coil 112 may be drawn into the distributor 100, or only a part of the heater coil 112 may be drawn into the distributor 100. have.

In the electric heating device according to the present invention configured as described above, as soon as the heater coil 112 for heating the water is heated in the distributor 100, the respective indoor spaces 10 are supplied to the pipes. The phenomenon that the temperature of the hot water falls can be prevented as much as possible, thereby increasing the energy efficiency. In addition, since the electric heating device according to the present invention heats the water inside the distributor 100, a separate boiler is not required, and thus the configuration is very simple, which significantly reduces the manufacturing cost and reduces the size of the entire product. There is an advantage that it can.

Meanwhile, the hot water is supplied only to the pipes installed in the first indoor space 11 and the second indoor space 12 among the four indoor spaces 10, and the third indoor space 13 and the fourth indoor space 14 are provided. If it is not necessary to supply hot water to the pipe installed in the user, the user operates the controller 800, the third supply water opening and closing valve 330 and the fourth supply pipe 240 installed in the third supply pipe 230, the fourth The supply water opening and closing valve 340 is closed, and the first supply water opening and closing valve 310 installed in the first supply pipe 210 and the second supply water opening and closing valve 320 installed in the second supply pipe 220 remain open. The hot water heated inside the distributor 100 is supplied only to the first supply pipe 210 and the second supply pipe 220 and not to the third supply pipe 230 and the fourth supply pipe 240. Can be. Of course, in this case, water is recovered only through the first recovery pipe 410 and the second recovery pipe 420 to the recovery device 500, and the third recovery pipe 430 and the fourth recovery pipe 440. Water is not recovered.

In this case, in order to enable the on-off valve to be operated by the operation of the controller 800, the on-off valve should be applied as an electronic valve, the electronic valve that is operated to open and close the flow path by the signal input as described above is applicable to the present invention. Since the product is widely commercialized in the art, a detailed description thereof will be omitted. As such, when the electric heating device according to the present invention is used, only some of the indoor spaces 10 of the plurality of indoor spaces 10 can be heated, so that the effect of energy saving can be obtained and hot water is supplied only by the operation of the controller 800. It is very easy to use because the route can be set.

On the other hand, the hot water heated by the heating device is not only used for heating for heating each indoor space 10, but may also be used as living water. Therefore, the electric heating device according to the present invention uses the water drawn-out pipe 700 for drawing out the water in the distributor 100 to the outside so that the user can use the hot water heated in the distributor 100 as the living water. The water opening and closing valve 710 for opening and closing the outlet pipe 700 may be further included. Of course, the controller 800 should be configured to control the operation of the use water on-off valve 710 when receiving the operation signal from the user.

At this time, since the amount of hot water heated in the distributor 100 is limited, the hot water inside the distributor 100 is supplied to the pipe of each indoor space 10 and at the same time supplied to the living water through the use water outlet pipe 700. If so, the user may not be able to use a sufficient amount of hot water he or she desires. In order to solve such a problem, the controller 800 may be configured to close all the feed water on / off valves 300 when opening the use water on / off valve 710. For example, when the user opens the hot water valve to use hot water as household water while the hot water generated in the distributor 100 is being used as the heating water through the supply pipe 200, the controller 800 supplies all the supply water. The open / close valve 300 may be configured to close and open only the use water open / close valve 710. In addition, even when the user selects the hot water exclusive mode in the state in which the electric heating apparatus according to the present invention is not operating, the controller 800 closes all the water supply valves 300 and only the water valves 710 used. Can be configured to open.

On the other hand, the larger the capacity of the distributor heater 110 can quickly heat the water inside the distributor 100, but the power consumption increases as the capacity of the distributor heater 110 increases, so the distributor heater 110 has an appropriate capacity. Is preferably selected. However, when more hot water is required, such as a hot water supply mode or a high speed heating mode, the distributor heater 110 alone has a disadvantage in that the user cannot continuously supply hot water at a satisfactory temperature. Therefore, in the electric heating device according to the present invention, as shown in this embodiment, a separate recovery heater 510 is provided in a recovery unit 500 in which water that has passed through all the pipes of each indoor space 10 is recovered. By passing the water cooled to low temperature while passing through the piping of the indoor space 10 in the recoverer 500 to the secondary in the distributor 100, it can be configured to generate hot water of a higher temperature. Thus, when a heater for heating water is provided not only in the distributor 100 but also in the recovery unit 500, the hot water of a higher temperature can be supplied when the hot water supply mode or the high speed heating mode is selected, and thus the user's satisfaction is very high. Even if the heater 110 fails, hot water can be supplied to the recovery heater 510 without a hitch until repair of the distributor heater 110 is completed, thereby increasing the user's reliability.

Compared with the distributor heater 110, the recovery heater 510 differs only in the mounting position whether the recovery heater 510 is mounted on the recovery machine 500 or the distributor 100, and the configuration and operation principle are substantially different. Since the same, detailed description thereof will be omitted.

4 is a perspective view of a cooling unit 900 included in the second embodiment of the electric heating apparatus according to the present invention, and FIG. 5 is a partial cross-sectional view of the second embodiment of the electric heating apparatus according to the present invention.

The electric heating apparatus according to the present invention may be configured to cool the indoor space 10 by cooling the water inside the distributor 100 and then supplying the pipes to the respective indoor spaces 10. That is, the electric heating device according to the present invention includes a compressor 910, a condenser 920, an expansion valve 930, and an evaporator 940, and the evaporator 940 is mounted to be introduced into the distributor 100. A cooling unit 900 for cooling the water in the distributor 100 may be further provided.

The cooling unit 900 is configured to endotherm the refrigerant phase-changed by the low-temperature low-pressure gas passing through the expansion valve 930 through the evaporator 940, as shown in this embodiment distributor 100 If the cooling unit 900 is further provided in the low-temperature water is supplied to the piping of each indoor space 10 it is possible to cool each indoor space (10). At this time, the cooling unit 900 phase-changes the gaseous refrigerant to a high temperature and high pressure liquid refrigerant in the compressor 910 and lowers the temperature of the liquid refrigerant in the condenser 920, and expands the low temperature and high pressure liquid refrigerant expansion valve 930. ) And endothermic reaction occurs in the evaporator 940 by rapidly expanding the gas phase into a low-temperature, low-pressure gas phase refrigerant. Such a cooling unit 900 is widely used in a conventional cooling device. Is omitted.

On the other hand, the heater coil 112 is generally formed long along the longitudinal direction of the recovery machine 500, wherein the evaporator 940 is the heater coil so that the entire outer surface of the heater coil 112 can be in contact with the water filled in the distributor 100. Parallel to 112 and may be formed to be spaced apart from the heater coil (112).

In addition, in order to further lower the temperature of the water discharged from the distributor 100, the cooling unit 900 may be equally installed in the recovery unit 500. When the cooling unit is installed in the distributor 100 and the recovery unit 500, respectively, the temperature of the water discharged from the distributor 100 can be further lowered, so that the cooling effect of the indoor space 10 can be further improved. There is an advantage that the cooling capacity can be adjusted by selectively operating the cooling unit 900 installed in the cooling unit 900 and the recovery unit 500 installed in the 100. At this time, since the cooling unit 900 installed in the recovery unit 500 is substantially the same as the cooling unit 900 installed in the distributor 100, a detailed description of the configuration and operation principle will be omitted.

Meanwhile, in the present embodiment, only the case where the separate cooling unit 900 is mounted to each of the distributor 100 and the recovery unit 500 is illustrated, but only one cooling unit 900 is provided, but the evaporator 940 is bifurcated. Branched to may be configured to be introduced into the distributor 100 and the recovery 500, respectively. Thus, only one cooling unit 900 is provided, but the two-pronged evaporator 940 is configured to be introduced into the distributor 100 and the recovery unit 500, respectively, even if only one compressor 910 and one condenser 920 are operated. Since the water in the distributor 100 and the collector 500 can be cooled, there is an advantage in that the amount of power consumed for cooling can be reduced.

6 is a perspective view of a cooling unit 900 included in the third embodiment of the electric heating apparatus according to the present invention.

The evaporator 940 for cooling the water supplied to the piping of the indoor space 10 may be formed in a linear shape to be parallel to the heater coil 112 as shown in FIG. 4, as shown in FIG. 6. Likewise, the heater coil 112 may be formed to surround the spiral. As shown in FIG. 6, since the length of the evaporator 940 is long to spirally surround the heater coil 112, the contact area with water is increased, thereby improving water cooling efficiency.

As such, when the evaporator 940 is formed in a spiral shape, the evaporator 940 may wrap the heater coil 112 to be in contact with the outer surface of the heater coil 112, and the outer surface of the heater coil 112. The heater coil 112 may be wrapped to be spaced apart. When the evaporator 940 contacts the outer surface of the heater coil 112 and surrounds the heater coil 112, the evaporator 940 and the heater coil 112 are fixedly coupled to each other so that the evaporator 940 and the heater coil 112 are fixed to each other. There is an advantage that the structural strength of the improved. In addition, when the evaporator 940 surrounds the heater coil 112 without being in contact with the outer surface of the heater coil 112, the area in which the evaporator 940 is in contact with the water and the heater coil 112 are in contact with the water. Since the area is increased, there is an advantage that the heating efficiency and the cooling efficiency are improved. That is, the shapes of the evaporator 940 and the heater coil 112 may be variously changed according to various conditions.
