Description

Thermal storage electric water heater partition structure

The present invention relates to an electric water heater; in particular, it relates to a partition structure of a heat storage electric water heater that can achieve the dual functions of preheating and instantaneous heat.

According to the general electric water heater, please refer to Fig. 1, it consists of an outer cylinder 1, and a partition 10 is welded to the inner wall of the outer cylinder 1, so that the interior of the outer cylinder 1 is divided into lower parts by the partition 10. The water storage area 11 and the upper water storage area 12; in addition, the separator 10 is provided with a heat flow hole 13 and a return hole 14 respectively, so that the heat flow hole 12 and the return hole 14 can communicate with the lower water storage area 11 and 14 respectively. In the upper water storage area 12, a hollow short tube 15 extending downward for an appropriate distance is formed on the outer peripheral side of the heat flow hole 13, so that one end of the heating tube 16 can be accommodated in the hollow short tube 15; The cylinder 1 is provided with a normal temperature water inlet pipe 17 connecting the normal temperature water source to the lower water storage area 11; 18; In this way, when the heating tube 16 starts to heat in the hollow short tube 15, the normal temperature water source distributed between the heating tube 16 and the hollow short tube 15 will directly absorb the heat generated by the heating tube 16. The heat energy increases the temperature of the water source, and the hot water source that has raised the temperature of the water source will flow upward through the heat flow hole 13 to the upper water storage area 12 for storage until it continues to flow into the upper water storage area 12. When the amount of hot water source is too much, it will flow to the lower water storage area 11 through the return hole 14; Finally, when the consumer is using hot water, the hot water source already located in the upper water storage area 12 will flow directly through the hot water outlet pipe 18 and then flow out toward the outside of the outer cylinder 1 for the consumer to use.

Although the above creation can achieve its creative purpose, however, in the process of operation and use, the following defects will occur:

Since the conventional outer cylinder is made of white iron, when the peripheral side of the partition plate is welded to the inside of the outer cylinder made of white iron, it will form an integral shape due to the action of the high temperature burning rod; however, the outer cylinder made of white iron passes through the high temperature After welding, the white iron material of the outer cylinder at the welding place will change in quality, so that rust will be formed on the periphery of the welding point between the partition plate and the outer cylinder that have been immersed in water for a long time, and then It is a big problem that the outer cylinder leaks water and must be replaced.

When consumers use hot water while heating, the hot water already located in the upper water storage area will first flow into the hot water outlet pipe to be discharged, and the normal temperature water source already located in the lower water storage area will be made to flow out. The water source on the peripheral side of the heating pipe flows into the upper water storage area from the return hole and the heat flow hole respectively, so that the normal temperature water source already located in the normal temperature water pipe can be injected into the lower water storage area; The normal-temperature water source injected into the lower water storage area will directly enter from the return hole, flow through the upper water storage area, and then flow out from the hot water outlet pipe, so that the initial water temperature of the hot water outlet pipe will be greatly reduced. , which in turn causes consumers to be troubled that the preset water temperature cannot be used for bathing in winter.

Therefore, how to develop a device that can effectively prevent water leakage and increase the temperature of hot water for continuous use by many people, improve its heating efficiency, and have environmental protection, energy saving, and carbon reduction is a technical issue that the industry needs to solve as a priority.

The main content of the partition structure of the heat storage electric water heater of the present invention is to provide a heating area and a heat collecting area respectively in the heat collecting sleeve, and the cross-sectional area of the heating area is smaller than that of the heat collecting area, and The heating zone is provided with a water inlet and an inner air chamber and an exhaust port are formed near the upper part of the heat collecting zone. The water port can be used to connect the heating area to the water storage area, and the exhaust port can be used to connect the inner air chamber to the top air chamber of the water storage cylinder, and make the highest water level line of the water storage area and the water storage area. The highest water level line of the heat collection area is completely separated and will not be directly connected; in this way, the present invention can completely overcome the problem of water leakage caused by qualitative change because the inner wall of the water storage tank does not need to be welded around, and can reduce consumption The replacement time and cost of the device can also make the heat energy of the hot air already filled in the top air chamber directly conducted to the water source on the surface of the highest water level line in the water storage area, so as to prevent the heating temperature in the heat collecting area from overheating. The phenomenon that the heating tube is abnormally damaged by pressing the water level line back due to high water level, and can increase the preheating water temperature in the water storage area to form a dual function of instantaneous heat and heat storage. At the same time, while using hot water, When heating, the dynamic water line of the normal temperature water source will be forced to flow through the heating zone before reaching the heat collecting zone or the hot water outlet pipe, so that the water volume of the high hot water source discharged to the outside of the water storage tank increases greatly, and It can provide more people with the effect of continuous shower use, and then achieve the effect of energy saving and carbon reduction, which is a progressive proposition.

The water storage cylinder 2 at least includes a water storage area 20 for water storage, and a top air chamber 21 that has been stored in the water storage area 20 from above the highest water level line formed in the water storage cylinder 2 to the inner top surface of the water storage cylinder 2;

The heating area 30 is surrounded by a water inlet 302 for the inflow of the normal temperature water source already located in the water storage area 20; the heat collecting area 31 is connected to the top cover plate by the top cover plate 311 The side ring plate 312 at 311 and the bottom plate 313 connected between the side ring plate 312 and the ring plate 301 are surrounded and formed, and are above the highest water level line of the heat collecting area 31 to the top cover plate 311. An inner air chamber 315 is formed between the The top cover plate 311 or the side ring plate 312 is provided with an exhaust port 316 connecting the inner air chamber 315 to the top air chamber 21 ; in addition, there is no direct connection between the heat collecting area 31 and the water storage area 20 . connected, and the cross-sectional area of the heating zone 30 is smaller than the cross-sectional area of the heat collecting zone 31;

The heating device 5 includes at least one or more heating tubes 51 and a bottom plate 50 for the heating tubes 51 to be assembled; the above-mentioned heating device 5 is an electric heating tube or the like;

One end of the normal temperature water inlet pipe 6 is connected to the normal temperature water source and the other end is connected to the interior of the water storage area 20;

The hot water outlet pipe 7 guides the hot water source to be output to the outside of the water storage tank 2 . The hot water outlet pipe 7 at least includes a hot water inlet 701 for the inflow of the hot water source, and outputs the hot water source to the outside of the water storage tank 2 . The conveying section 71 used, and the surrounding section 70 formed from the hot water inlet 701 to the conveying section 71 in a connected shape, the surrounding section 70 is located above the horizontal line of the heating pipe 51, and the surrounding section 70 is located in the In addition, the output section 71 is located between the heating area 30 of the heat collecting sleeve 3 and the heating pipe 51, and the output section 71 will pass through the water inlet 302 and then communicate with each other to the outside of the water storage tank 2, so that the hot water source located in the heat collecting area 31 is output and sent to the outside of the water storage tank 2; and the above-mentioned output section 71 is preferably arranged in a straight strip;

When the normal temperature water source is to be injected into the water storage area 20 of the water storage tank 2, the normal temperature water source that has already flowed in will start from the bottom of the water storage area 20 and the accumulated water level will rise upward, and the rising normal temperature water source will flow from the water storage area 20. The nozzle 302 flows into the heat collecting sleeve 3, and the heating zone 30 and the water storage zone 20 are simultaneously injected by the normal temperature water source until the water level line of the normal temperature water source that has flowed into the heat collecting zone 31 exceeds the heat outlet at the heat collecting zone 31 Only after the water level of the hot water inlet 701 of the water pipe 7 is high, can the normal temperature water source flow into the hot water outlet pipe 7 until it is full. In this way, the supply of the normal temperature water source will be automatically cut off, and the The highest water level line of the water storage area 20 and the highest water level line of the heat collection area 31 are maintained at the same height, and the upper half of the water storage area 20 and the water collection area 31 are separated and separated without direct communication. The phenomenon;

Please refer to FIG. 2, when heating without using hot water, due to the setting of the heat collecting sleeve 3, the upper half of the water storage area 20 of the water storage cylinder 2 and the heat collecting area of the heat collecting sleeve 3 31 is separated and disconnected, and the lower half of the water storage area 20 is connected to the lower half of the heating area 30 of the heat collecting sleeve 3 only through the setting of the water inlet 302, and the heating area 30 is used. The cross-sectional area of the heating tube 51 is slightly larger than the area that the heating tube 51 can accommodate. Therefore, when the heating tube 51 is continuously activated to generate high-temperature heat energy, the space limitation and obstruction of the heating area 30 of the heat collecting sleeve 3 will occur. Therefore, the heat energy generated by the heating pipe 51 cannot be diffused in the horizontal direction, and a synergistic effect of centralized heating is formed, so that the normal temperature water source located on the peripheral side of the heating pipe 51 (that is, located in the heating zone 30) will be Therefore, the high temperature is instantly and rapidly increased, so that the high temperature water source in the heating zone 30 will quickly flow upward and gather at the highest water level line of the heat collecting zone 31; at this time, it is located at the highest water level of the water storage zone 20 The normal temperature water source at the line will have two paths for absorbing heat energy. One is to conduct the heat energy of the hot water source located at the highest water level line of the heat collecting area 31 to the heat collecting sleeve 3 through the action of the heat-conducting material of the heat collecting sleeve 3 itself. Located at the highest water level line of the water storage area 20; the other is the air already located in the inner air chamber 315 It will directly absorb the heat energy of the hot water source adjacent to the surface of the highest water level line of the heat collecting area 31, so that the temperature of the air will be raised and converted into hot air. After the hot air rises, it will be discharged through the exhaust port 316. Flow into the top air chamber 21 until the top air chamber 21 is continuously filled with hot air, the hot air already located in the top air chamber 21 is adjacent to the surface of the highest water level line of the water storage area 20, and the So that the warm water source located on the surface of the highest water level line of the water storage area 20 will absorb the thermal energy of the hot air and increase its water temperature until the temperature sensing element (not shown in the figure) disposed in the water storage area 20 reaches the The heating of the heating tube 51 can only be cut off after the predetermined setting value; at this time, the water temperature layer in the upper half of the water storage area 20 at the same level will be lower than the heat collecting area 31 of the heat collecting cylinder 3 The water temperature layer, however, the heat collecting sleeve 3 is made of a thermally conductive material (such as metal material, etc.), so the heat energy in the heat collecting area 31 is slowly transferred to the water storage area 20 At the half stage, until the water temperature in the upper half of the water storage area 20 and the water temperature in the heat collection area 31 tend to be in equilibrium, and finally, when the water temperature in the water storage area 20 drops to the temperature Only when the preset low temperature value of the component (not shown in the figure) can the heating tube 51 be activated again to generate heat energy; such a cycle of repeated heating eliminates the need for any welding work around the inner wall of the water storage cylinder 2. In order to completely overcome the problem of water leakage caused by the qualitative change of the conventional water storage cylinder, and can reduce the replacement time and cost of consumers, at the same time, it can also prevent the heating temperature in the heat collecting area 31 from being too high and the water level in the water level line. The phenomenon that the heating pipe 51 is abnormally damaged by the pressure back, and can increase the temperature of the preheated water at the highest water level line of the water storage area 20 .

Referring to Figure 3, when the hot water is being heated in use, the hot water source located in the hot water outlet pipe 7 will flow directly to the outside of the water storage tank 2 and then be discharged. Therefore, the high-temperature layer water source located on the periphery of the hot water inlet 701 of the hot water outlet pipe 7 is directly inhaled, and at the same time, the water source located in the heat collecting area 31 and the heating area 30 will flow upward accordingly, and It can drive the water source already located in the water storage area 20 to flow into the heating area 30 through the water inlet 302, and make the normal temperature water source located in the normal temperature water inlet pipe 6 to be injected into the water storage area 20. In other words, the normal temperature water source that has been located in the normal temperature water inlet pipe 6 will flow through the water storage area 20, the water inlet 302, the heating area 30, and the heat collection area 31 in sequence, and make the water flow through the The instantaneously heated warm water source in the heating zone 30 can be partially mixed with the high hot water source already located in the heat collecting zone 31, and then the hot water source located at the periphery of the hot water inlet 701 of the hot water outlet pipe 7 will be mixed together. Inhalation (that is, the so-called dynamic water line) is given in a proportional way and discharged to the outside of the water storage tank 2 for consumers to use, so that the temperature of the normal temperature water source in use can be quickly raised to the temperature of the high hot water source, In addition to the effect of instantaneous heat, at the same time, the water volume of the high hot water source discharged to the outer side of the water storage tank 2 can be increased, so as to provide the effect of continuous shower use by more people;

With the above structure, the present invention utilizes the heat collecting sleeve 3 disposed inside the water storage cylinder 2, so that the heat collecting area 31 and the water storage area 20 are not directly communicated, and the exhaust port 316 can communicate with each other. to the top air chamber 21; in addition, the hot water inlet 701 of the hot water outlet pipe 7 is located in the heat collecting area 31 of the heat collecting sleeve 3, so that the normal temperature water sources already located in the water storage area 20 must be sequentially After flowing through the water inlet 302 and the heating pipe 51, it can gather at the heat collecting area 31; in this way, it can not only be heated in the static and not in use, but also be located in the heat collecting sleeve 3 The formed high temperature gas will be guided and discharged into the top gas chamber 21 through the exhaust port 316, and the The hot air in the top air chamber 21 will be adjacent to the surface of the highest water level of the water storage area 20, so that the thermal energy of the hot air is conducted to the surface of the highest water level of the water storage area 20, so as to prevent the In addition to the phenomenon that the temperature in the heat collection area 31 is too high, at the same time, when the hot water is heated in use, the normal temperature water source can be forced to flow through the water inlet 302 and then flow through the heating pipe 51 circumference, and The normal temperature water source is instantly turned into a hot water source and continues to flow to the heat collecting area 31 for accumulation, and then the hot water source passes through the hot water inlet 701, the surrounding section 70 already located in the heat collecting area 31, and the flow in sequence. The heating zone 30 that has been located between the heat collecting sleeve 3 and the heating pipe 51 is then output to the outside of the water storage cylinder 2, so that it has instantaneous heat and increases the reserve hot water storage capacity, thereby achieving energy saving and carbon reduction. effect.
