Description

Thermal storage type electric water heater sectional heating structure

The present invention relates to a heat storage type electric water heater; in particular, to a sectional heating structure of a heat storage type electric water heater.

According to the general electric water heater structure, please refer to Figure 1, which is based on the approval certificate number No. I308206 of April 1, 1998, "The structure of electric water heater with heat storage and instant heat". The heat storage tube 10 is provided with a partitioning plate 20, and the heat storage tube 10 is provided with a cold water inlet pipe 30 and a hot water outlet pipe 40 disposed inside and outside the cylinder, and is heated by the water inside the heat storage cylinder 10, and the heat storage cylinder 10 The medium heat is provided with an electric heater 50, wherein the partition plate 20 is in the shape of a crucible, so that the heat storage cylinder 10 is divided into a heat storage space 12 and an instant heat space 13, and the heat storage space 12 extends to the upper half. In the lower space, the instantaneous heat space 13 extends to the front upper space for the lower half; and the hot and cold mixed exchange space 121 is below the heat storage space 12, and the high temperature space 131 is above the instantaneous heat space 13, and the partition plate 20 is stored. An upper through hole 22 is defined in the vertical partition 21 on the hot space 12 and the instantaneous heat space 13, and a lower through hole 24 is arranged in the lower vertical partition 23, and the cold water inlet pipe 30 is connected to the water flow at normal temperature, and the connection is made. Go to the position of the hot and cold mixed exchange space 121 of the heat storage space 12, and the cold water inlet pipe 30 At the outlet 10 and the heat storage tanks provided with a sensor 60, a hot water outlet 40 to the exterior space 131 from a high temperature instant heating space 13 of the For guiding the water flow heated to the set temperature for use, the electric heater 50 is placed in front of the heat storage cylinder 10 and bent to extend to a length space below the instantaneous heat space 13, and the electric heater 50 It is a connection sensor 60; with the above structure, the cold water inlet pipe 30 is used to introduce a water flow for the hot and cold mixed exchange space 121, and enters the instantaneous heat space 13 through the lower through hole 24, and the electric heater 50 is in the instantaneous heat. The space 13 heats the water source, and the hot water flows from the instantaneous heat space 13 to the high temperature space 131, and flows out of the hot water outlet pipe 40, and partially passes through the upper through hole 22 to the heat storage space 12.

Although the above creation can achieve its creative purpose, in the process of its operation and use, the following defects will occur: the conventional technology is mainly provided with upper and lower through holes on the upper and lower vertical partitions of the partition plate. The upper and lower through holes serve as a basis for the communication between the heat storage space and the instantaneous heat space. In addition, the electric heater is located in the lower half of the instantaneous heat space; therefore, when the electric heater is heated, The hot water generated by the electric heater starts to flow upward gradually, and flows to the heat storage space through the upper through hole during the flow, and then flows again through the lower through hole. In the instantaneous heat space, a heating mode of thermal circulation flowing through the upper and lower through holes is formed until the normal temperature cold water in the entire heat storage cylinder (including the heat storage space and the instantaneous heat space) becomes a preset temperature value, thus, It will cause the initial water temperature that has flowed into the instantaneous heat space to be lower, so that the heating time to be heated to the predetermined temperature will become longer, and at the same time, at least between the heat storage space and the instantaneous heat space will be provided. More than two Lower through-hole communicating them, and the more easily formed vertically circulating flow of convection mode, when the amount of water to cause the region to be heat reaches instantaneous space becomes a predetermined heating temperature of the whole heat storage tanks The total amount of water, and thus the inability to achieve rapid instantaneous heat supply, is a major problem.

As described above, when the hot water flowing through the electric heater flows from the lower half of the instantaneous heat space to the high temperature space 13, the normal temperature cold water that has been stored in the water storage space and located at the side of the upper through hole can also be Flowing from the upper through hole and directly mixing with the hot water flowing to the high temperature space 13 (ie, away from the electric heater), so that the hot water is mixed and then cooled to reach the high temperature. At the end of the space 13, at the end, it flows out through the hot water outlet pipe. As a result, the temperature of the hot water flowing out of the hot water outlet pipe is lower than the predetermined temperature, so that the heat energy is invisibly lost, and thus the environmental protection and energy saving are not achieved. The effect is a big problem.

Therefore, how to develop a time that can effectively shorten the reheating time, reduce the loss of intangible heat energy, and improve its heating efficiency and environmental protection and energy conservation is a technical problem that the industry needs to solve first.

In view of this, the creator is actively researching and developing, and in order to improve the above-mentioned lack of heat storage and instant heat electric water heater structure, the creator has long been working hard to study and experiment with the experience of being engaged in the manufacture of such products for many years. Finally, we have developed and designed the heat storage electric water heater segment heating structure of this creation, which can benefit all consumers and manufacturers.

The main content of the segmented heating structure of the heat storage electric water heater of the present invention is to provide a partition of the outer cylinder into a water storage zone and a heating zone by a partition, and respectively set the water storage zone at a proper position. Providing the external water inlet position and the first water discharge port, and respectively arranging the heating element at a suitable position of the heating zone The hot water outlet position, the second water discharge port, and the exhaust device; further, the water intake position is disposed between the partition plate and the inner wall surface of the outer cylinder, and the water intake position of the water intake position is The height needs to be set at a horizontal position above one-half of the total height of the outer cylinder or the horizontal position of the water intake port that has been located at the water-removing position is higher than the topmost edge of the heating position of the heating element; The horizontal position of the inlet port of the inner end of the exhaust device is higher than the horizontal position of the top edge of the heating element of the heating element (ie, the heating pipe) and the horizontal position of the inlet end of the hot water outlet position; In this way, it can not only ensure that the amount of hot water stored can be maximized, but also can control the temperature of the water intake due to the different settings of the inlet and outlet of the hot water outlet position, in order to meet the CNS of China. The use of the test standard will not cause the accidental danger of the user who is immediately burned, and can achieve the effect of providing hot water to more people for continuous use; in addition, the creation can greatly improve the heating zone.

The top edge of the position (ie, the heating tube 121); the heating element 12 is an electric heating tube or an electric heater, and is assembled at the outer tube 1; and the heating element 12 includes at least one a seat body 120 fixed to the outer tube 1 and a set of the base body The heating pipe 121 at 120, and the heating pipe 121 after installation needs to be placed in the heating zone 101, and the top edge of the heating position of the heating pipe 121 does not exceed the top edge of the water intake port 301. The horizontal position may not exceed the horizontal position of the air inlet 80 of the exhaust device 8; the hot water outlet position 13 includes at least an inlet end 130 for the hot water inflow in the heating zone 101. And the horizontal position of the inlet end 130 is higher than the top edge of the heating position of the heating tube 121 of the heating element 12. The horizontal position is high; in addition, the lowest horizontal position of the inlet end 130 is higher than the lowest horizontal position of the water intake 301, and the inlet end 130 is located at least two-thirds of the total height of the inner side of the heating zone 101. The height position is optimal; and the hot water outlet 13 is preferably a hollow tube; the exhaust device 8 is disposed at the outer tube 1 or the seat 120 of the heating element 12, And an air inlet 80 of an inner end thereof is connected to the inside of the outer cylinder 1 (ie, the heating zone 101 or the water storage zone 100), and the exhaust port 81 of the other outer end is connected to the outer cylinder. 1 outside; and the exhaust device 8 includes at least an air inlet 80 connected to the inner water storage area 100 of the outer cylinder 1, an exhaust port 81 connected to the outside of the outer cylinder 1, and a control The intake port 80 and the exhaust port 81 and the on-off valve 82 for communicating with the outside of the outer tube 1 , and the switch valve 82 can be disposed at one end of the exhaust port 81 or at the intake port 80 . Between the exhaust ports 81, the setting of the on-off valve 82 controls whether the air inlet 80 to the exhaust port 81 are connected according to each other; The horizontal position of the inner end inlet port 80 of the exhaust device 8 at the inner portion of the outer cylinder 1 is higher than the horizontal position of the hottest position of the heating element 12 (i.e., the heating pipe 121) and the hot water discharge position 13 The horizontal position of the inlet end 130 is high; when it is first installed and used, it is only necessary to first open the on-off valve 82 of the exhaust device 8 so that the intake port 80 and the exhaust port 81 of the exhaust device 8 are The outer side of the outer cylinder 1 is in a communicating state, and the normal temperature water source flows into the water storage area 100 through the external water inlet position 11 until the horizontal temperature of the normal temperature water source that has flowed into the water storage area 100 is higher than The water intake position 30 After the mouth 301, the normal temperature water source can flow through the water intake port 301 and the water discharge port 302 and then flow into the heating zone 101 until the horizontal line height of the normal temperature water source completely covers the air inlet 80 blocked by the exhaust device 8. Up to the point that the normal temperature water source located in the water storage area 100 and the heating zone 101 is maintained in an equilibrium state, so that the horizontal plane of the normal temperature water source located at the air inlet 80 is to the water storage area 100. The gas in the sealed gas chamber 1001 formed between the top inner wall surfaces can no longer be discharged outside the outer cylinder 1, and the ambient temperature water source can no longer be continuously flowed into the water storage area 100. Forming a phenomenon of temporarily stopping the water supply, at this time, the switch valve 82 can be rotated to be in a closed state, so that an open circuit is formed between the air inlet 80 and the exhaust port 81 of the exhaust device 8 and the outer side of the outer tube 1. In the state of disconnection; at this time, if the heating element 12 is activated and the heating pipe 121 starts to generate thermal energy, the normal temperature water source located at the circumferential side of the heating pipe 121 can directly absorb the heat energy and start to heat up.

The heating rate of the normal temperature water source at the wall surface is slower than the heating water source of the heating zone 101 located near the heating element 12; at this time, the normal temperature of the heating zone 101 can be first set by the action of continuous heat convection. The water source is converted into the highest temperature hot water and continues to flow upward until the highest temperature layer of the highest temperature hot water that has been located in the heating zone 101 floats near the highest water surface of the heating zone 101 and will be affected by heat convection. Already located in the heating zone 101 The highest temperature layer of the highest hot water is convectively diffused in a lateral manner to the highest water surface of the water storage area 100 until the water source located in the heating zone 101 can reach a predetermined temperature, so that the heating element 12 can automatically stop operating; At this time, since the height position of the inlet end 130 of the hot water discharge device 13 is lower than the horizontal position of the air inlet 80 of the exhaust device 8, and the inlet end 130 is at an appropriate height of the stored hot water amount (ie, Not at the highest level, in addition, the temperature of the water stored in the hot water is proportional to the position of the stored height, so that the water source of the non-high temperature layer storing the hot water can be directly from the inlet end 130 The external supply and outflow use, at the same time, an equal amount of normal temperature water source (ie, the normal temperature water source is directly injected into the temperature sensing component to activate the heating element 12 to generate thermal energy) is flowed into the water storage area 100 and will be located. The heated water source near the left side wall of the partition 3 is pushed upward until the reheated water source (i.e., the higher temperature layer in the water storage area 100) that continues to be heated and flows upward can be easily taken from the water take-up position 30. The port 301 flows into the heating zone 101 as a control operation for providing the temperature of the starting water source for the heating element 12 to be reheated; thus, not only can the amount of stored hot water be maximized, At the same time, the horizontal position of the inlet end 130 using the hot water discharge position 13 is lower than the inner end air inlet 80 of the exhaust device 8 so that the inlet end 130 of the hot water discharge position 13 can be from a predetermined height (ie, not the highest level). In the temperature layer of the stored hot water, the hot water in accordance with the standard quality is taken out directly, so that the accidental risk of the user can be met in accordance with the test standard and the hot water can be supplied to the multi-person. The effect of the use; in addition, the creation enables the higher temperature layer of the heated water source located in the water storage area to be DC into In the heating zone 101, as the heating element 12 is intended to be reheated, the temperature of the initial water temperature layer for reheating in the heating zone 101 is greatly increased, and the initial water temperature layer can be further improved. Close to the preset temperature value to effectively shorten the required reheating time and provide faster heating efficiency, which can greatly reduce the loss of intangible heat energy and effectively improve the use of its thermal efficiency, thereby achieving environmental protection and energy saving. efficacy.
