Description

Technical Field

[0001] The utility model relates to the technical field of electric energy storage heating, in particular to an electric energy storage heating device. Background Art

[0002] The electric energy storage heating device mainly converts electrical energy into thermal energy and stores it in the thermal storage body during the period of low electricity consumption. During the period of peak electricity consumption, the heat stored in the thermal storage body is released to provide thermal energy for users. The circulating fan is used to circulate the gas inside the electric energy storage heating component. When the airflow passes through the thermal storage body, it exchanges heat with the thermal storage body to provide heat for the circulating gas. When the gas passes through the heat exchanger, it exchanges heat with the heat exchanger to provide heat for the heat exchanger, thereby heating the water in the heat exchanger.

[0003] However, when the airflow passes through the heating device, it only contacts the surface of the heat storage body in the heating device for heat exchange, and the efficiency of the heat exchange is low. Utility Model Content

[0017] Reference Figure 1-2 The utility model proposes an electric energy storage heating device, including a shell 1, an electric heat storage block 2, a driving mechanism 3, and a sealing member 4. The shell 1 has an air inlet and an air outlet opened thereon, both of which are connected to a first air duct 11. The electric heat storage block 2 has a plurality of second air ducts 21, and the plurality of second air ducts 21 extend along a first direction and are sequentially arranged in intervals in a second direction. The first direction is perpendicular to the second direction. The driving mechanism 3 drives the connecting sealing member 4 to drive the sealing member 4 to move in the second direction. When the sealing member 4 moves in the second direction, the second air duct 21 can be opened or blocked.

[0018] The electric heat storage block 2 includes a plurality of electric heat storage bodies arranged in sequence along the second direction, and a second air duct 21 is formed between two opposite walls of two adjacent electric heat storage bodies, thereby increasing the contact area between the airflow and the electric heat storage block 2. At the same wind speed and time, the heating efficiency is higher and heat can be provided quickly.

[0019] When the second air duct 21 is in a fully open state, refer to Figure 1When the second air duct 21 is in a completely blocked state, please refer to Figure 3 .

[0020] When rapid heating is required, multiple second air ducts 21 are opened, and heat is exchanged when the airflow passes through the second air ducts 21, thereby improving the heat exchange efficiency. In addition, the electric heat storage block 2 has an insulating shell. When heating is not required, the second air ducts 21 are blocked to store heat in the electric heat storage block 2.

[0021] Specifically, the driving mechanism 3 drives the seal 4 to move along the second direction, and the multiple first sealing portions 41 on the seal 4 can be arranged one-to-one with the multiple second air ducts 21 so that the first sealing portions 41 block the second air ducts 21, and the multiple through holes 42 on the seal 4 can correspond one-to-one with the multiple second air ducts 21 to connect the first air duct 11 and the second air duct 21, and the multiple first sealing portions 41 and the multiple through holes 42 are arranged in sequence in the second direction.

[0022] It should be noted that when the second air duct 21 is switched between open and blocked by the sealing member 4, it includes three states: the second air duct 21 is arranged relative to the first sealing portion 41, and the second air duct 21 is in a completely blocked state; the through hole 42 is arranged relative to the second air duct 21, and the second air duct 21 is in a completely open state; when the sealing member 4 moves, the second air duct 21 may also be between the two states, and the second air duct 21 is in a semi-open state, for details, refer to Figure 4 The air inlet of the second air duct 21 is in a state of gradually increasing or decreasing, so that the air volume passing through the multiple second air ducts 21 can be adjusted simultaneously. At this time, in order to avoid the increase in pressure in the shell 1 due to the unchanged air inlet volume and the reduced air outlet volume, the first air duct 11 is also in a semi-open state.

[0023] In the same time period, the air volume passing through the first air duct 11 is equal to the sum of the air volumes passing through the plurality of second air ducts 21 .

[0024] In the above embodiment, the seal 4 also has a second sealing portion 43 extending along the second direction. When the multiple through holes 42 on the seal 4 are arranged one-to-one with the multiple second air ducts 21, the second sealing portion 43 is located in the second air duct 21 to block the second air duct 21.

[0025] In order to avoid the problem of heat loss caused by closing only one end of the second air duct 21, there are two seals 4, and the two seals 4 are respectively located at the two ends of the second air duct 21 to respectively open or block the inlet and outlet of the second air duct 21. There is a connecting piece 5 between the two seals 4 for fixing the two seals. The driving mechanism 3 drives the two seals 4 to be connected together through the connecting piece 5, thereby reducing production costs.

[0026] In the above embodiment, the driving mechanism 3 can use but is not limited to using the cylinder 32 as the power source. However, since the interior of the device is in a high temperature state, the cylinder 32 or other power parts are directly located in the shell 1 and connected to the connecting member 5. Then the high temperature environment will affect the service life of the driving mechanism 3. In order to better protect the power source, the driving mechanism 3 also includes a connecting rod 31. One end of the connecting rod 31 extends into the shell 1 through an assembly hole opened on the shell 1 and is fixedly connected to the connecting member 5. The cylinder 32 is located outside the shell 1 and its output end is fixedly connected to the end of the connecting rod 31 located outside the shell 1.

[0027] The through hole 42 is in a trumpet shape with the expanded end facing the first air duct 11 .

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
