Description

Technical Field

[0001] This application relates to the field of thermal storage electric boiler technology, and more specifically, to a thermal storage electric boiler. Background Technology

[0002] A thermal storage electric boiler is a device that combines electric heating and thermal energy storage technologies. It is mainly used for heating or hot water supply, and achieves energy saving and cost reduction by storing heat during off-peak electricity periods and releasing heat during peak periods.

[0003] Traditional thermal storage electric boilers have the following shortcomings: In operation, they typically heat the thermal storage medium with electricity at night or during off-peak electricity hours, storing the heat energy. During the day or peak electricity consumption periods, the stored heat energy is released through a circulation system to meet heating or hot water needs. To improve the thermal storage effect of the ceramic, porous ceramics are often used. However, the numerous pores inside the porous ceramic significantly reduce the material's density, creating countless stress concentration points. Furthermore, the installation and disassembly of porous ceramics usually involve hoisting, during which the ceramic plates are prone to collisions with the boiler's inner wall, supports, or adjacent components, leading to edge cracking or the propagation of internal micro-cracks due to their brittle nature. Therefore, improvements are needed. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this application provides a thermal storage electric boiler that has the advantage of protecting porous ceramics.

[0005] To achieve the above objectives, this application provides the following technical solution: a thermal storage electric boiler, comprising a shell, a thermal storage tank being provided on the rear side of the shell, a thermal storage mechanism being provided inside the thermal storage tank, the thermal storage mechanism comprising a first push plate, an mounting box being placed above the first push plate, a perforated ceramic plate being bolted inside the mounting box, an insert plate being welded to the lower side of the mounting box extending through the lower side of the first push plate, movable grooves being provided on both sides of the insert plate, an inclined plate being slidably installed inside the movable groove, a second push plate being slidably installed inside the movable groove, and a telescopic spring being elastically installed between the inner side of the second push plate and the inner side of the movable groove.

[0006] As a preferred technical solution of this application, U-shaped plates are bolted to the bottom of both sides of the heat storage tank, and four sets of vertical plates are bolted to the bottom of the first push plate. Each set of vertical plates includes two vertical plates, and rollers are rotatably installed between the inner sides of the two vertical plates. The rollers are rotatably connected to the inside of the U-shaped plates.

[0007] As a preferred technical solution of this application, the movable groove is provided with sliding grooves on both sides, and the bottom sides of the inclined panel are welded with sliders that are slidably connected inside the sliding grooves.

[0008] As a preferred technical solution of this application, positioning blocks are uniformly welded to the bottom of the first push plate, and the positioning blocks are respectively located on both sides of the inclined plate.

[0009] As a preferred technical solution of this application, the thermal storage electric boiler is provided with air inlet pipes on both sides of the bottom, and a back plate is bolted to the rear side of the thermal storage electric boiler.

[0010] As a preferred technical solution of this application, the porous ceramic plate has uniformly opened circular holes on its surface, and silicon carbide rods are bolted to the inner side of the heat storage tank, with the silicon carbide rods passing through to the outer side of the circular holes in sequence.

[0011] Compared with the prior art, the beneficial effects of this application are as follows:

[0012] 1. This application involves installing a porous ceramic plate inside the mounting box, and then inserting an insert plate into the first push plate. When the insert plate is fully inserted into the bottom of the first push plate, the upper surface of the inclined panel contacts the lower surface of the first push plate, thus fixing the insert plate. Compared with traditional thermal storage electric boilers, this thermal storage electric boiler uses an inclined panel to assist in fixing the insert plate. The inclined surface of the inclined panel assists the insert plate in inserting into the first push plate, and the flat surface of the inclined panel contacts the first push plate for fixation. This allows the porous ceramic plate to be pre-installed above the first push plate and then pushed in as a whole, reducing the operational risks in the narrow space inside the boiler. At the same time, it can be quickly positioned, reducing downtime losses.

[0013] 2. This application improves the heating efficiency of the porous ceramic plate by embedding silicon carbide rods into the porous ceramic plate and directly heating them with electricity; in conjunction with an external electric heater, hot air is generated to circulate and heat the porous ceramic plate, thereby improving the heating efficiency of the porous ceramic plate. Compared with traditional thermal storage electric boilers, this thermal storage electric boiler heats the surface of the porous ceramic plate by setting multiple evenly distributed silicon carbide rods, thereby making the heating range of the porous ceramic plate equal and improving the thermal storage effect.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0022] like Figures 1 to 5 As shown, the thermal storage electric boiler 1 provided in this application includes a shell 11, a thermal storage tank 14 is provided on the rear side of the shell 11, a thermal storage mechanism 4 is provided inside the thermal storage tank 14, the thermal storage mechanism 4 includes a first push plate 401, an installation box 402 is placed above the first push plate 401, a perforated ceramic plate 403 is bolted inside the installation box 402, an insert plate 407 is welded to the bottom of the installation box 402 and extends to the lower side of the first push plate 401, movable grooves 408 are provided on both sides of the insert plate 407, a sloping plate 409 is slidably installed inside the movable groove 408, a second push plate 410 is slidably installed inside the movable groove 408, and a telescopic spring 411 is elastically installed between the inner side of the second push plate 410 and the inner side of the movable groove 408.

[0023] First, the porous ceramic plate 403 is installed inside the mounting box 402. Then, the mounting box 402 is installed on the first push plate 401, and the insert plate 407 below the mounting box 402 is inserted downward into the interior of the first push plate 401. When the inclined plate 409 contacts the upper side of the first push plate 401, under the pressure of the first push plate 401, the lower inclined surface of the inclined plate 409 is compressed inward, causing the inclined plate 409 to retract into the interior of the movable groove 408. At the same time, the inclined plate 409 moves inward to press the second push plate 410, causing the second push plate 410 to move inward to press the telescopic spring 411, causing the telescopic spring 411 to deform. After the insert plate 407 is fully inserted into the bottom of the first push plate 401, the telescopic spring 411 releases its elastic potential energy to push the inclined plate 409 outward, so that the upper side plane of the inclined plate 409 contacts the lower side of the first push plate 401, thereby fixing the insert plate 407, thus installing the mounting box 402 above the first push plate 401, and then pushing the first push plate 401 into the heat storage tank 14, thereby installing the heat storage mechanism 4 inside the heat storage tank 14.

[0024] By installing the porous ceramic plate 403 inside the mounting box 402, and then inserting the insert plate 407 into the first push plate 401, the upper surface of the inclined panel 409 contacts the lower surface of the first push plate 401 after the insert plate 407 is fully inserted into the bottom of the first push plate 401, thereby fixing the insert plate 407. Compared with traditional thermal storage electric boilers, this thermal storage electric boiler uses the inclined panel 409 to assist in fixing the insert plate 407. The inclined surface of the inclined panel 409 assists the insert plate 407 in being inserted into the first push plate 401, and the flat surface of the inclined panel 409 contacts the first push plate 401 for fixing. This allows the porous ceramic plate 403 to be pre-installed above the first push plate 401 and then pushed in as a whole, reducing the risk of operation in the narrow space inside the boiler, and enabling quick positioning to reduce downtime losses.

[0025] U-shaped plates 13 are bolted to the bottom of both sides of the heat storage tank 14. Four sets of vertical plates 405 are bolted to the bottom of the first push plate 401. Each set of vertical plates 405 includes two vertical plates 405. Rollers 406 are rotatably installed between the inner sides of the two vertical plates 405. The rollers 406 are rotatably connected to the inside of the U-shaped plates 13.

[0026] After the mounting box 402 is installed above the first push plate 401, the roller 406 is placed inside the U-shaped plate 13 and the first push plate 401 is pushed inward, so that the roller 406 moves inward along the U-shaped plate 13, thereby installing the heat storage mechanism 4 inside the heat storage tank 14.

[0027] The movable groove 408 has sliding grooves 412 on both sides, and the bottom sides of the inclined plate 409 are welded with sliders 413 that are slidably connected inside the sliding grooves 412.

[0028] Under the pressure of the first push plate 401, the inclined plate 409 is retracted into the movable groove 408. The slider 413 moves with the inclined plate 409 inside the groove 412, thereby limiting the inclined plate 409.

[0029] The bottom of the first push plate 401 is uniformly welded with positioning blocks 414, which are located on both sides of the inclined plate 409.

[0030] The positioning block 414 limits the two sides of the inclined panel 409, thereby effectively preventing the inclined panel 409 from expanding due to heat and affecting the disassembly operation.

[0031] Among them, the thermal storage electric boiler 1 has air inlet pipes 2 on both sides of the bottom, and a back plate 3 is bolted to the rear side of the thermal storage electric boiler 1.

[0032] After the heat storage mechanism 4 is installed inside the heat storage tank 14, the back plate 3 is closed, hot air is generated by the external electric heater, and the hot air is sent into the heat storage electric boiler 1 through the air inlet pipe 2. Correspondingly, the top of the heat storage electric boiler 1 is provided with an exhaust pipe. The hot air circulates in the heat storage tank to heat the porous ceramic plate 403 for heat storage. Then the exhaust gas is discharged from the exhaust pipe at the top, completing the heat energy storage process.

[0033] The porous ceramic plate 403 has multiple round holes 404 evenly distributed on its surface. A silicon carbide rod 12 is bolted to the inner side of the heat storage tank 14 and passes through the round holes 404 one after another. The spacing between the multiple round holes 404 is equal.

[0034] Multiple round holes 404 (e.g., four round holes 404) are made on the surface of the porous ceramic plate 403. After the porous ceramic plate 403 is pre-installed above the first push plate 401, it is pushed in as a whole. The silicon carbide rods 12 are inserted into the round holes 404 in sequence. Then the back plate 3 is closed. Hot air is generated by an external electric heater to circulate and heat the porous ceramic plate 403. At the same time, the silicon carbide rods 12 are energized to generate heat energy to assist in heating the porous ceramic plate 403.

[0035] By embedding silicon carbide rods 12 into the porous ceramic plate 403 and directly heating it with electricity, and by generating hot air in conjunction with an external electric heater to circulate and heat the porous ceramic plate 403, the heating efficiency of the porous ceramic plate 403 is improved. Compared with traditional thermal storage electric boilers, this thermal storage electric boiler heats the surface of the porous ceramic plate 403 by setting multiple evenly distributed silicon carbide rods 12, so that the heating range of the porous ceramic plate 403 is equal and the heat storage effect is improved.

[0036] The working principle and usage process of this application:

[0037] First, the porous ceramic plate 403 is installed inside the mounting box 402. Then, the mounting box 402 is lifted, allowing the insert plate 407 to be inserted into the first push plate 401. When the inclined plate 409 contacts the upper side of the first push plate 401, under the pressure of the first push plate 401, the lower inclined surface of the inclined plate 409 is compressed inward, causing the inclined plate 409 to retract into the movable groove 408. At this time, the slider 413 follows the inclined plate 409 and moves inside the sliding groove 412, thus limiting the inclined plate 409. Simultaneously, the inward movement of the inclined plate 409 compresses the second push plate 410, causing the second push plate 410 to... The internal movement compresses the telescopic spring 411, causing it to deform. When the insert plate 407 is fully inserted into the bottom of the first push plate 401, the telescopic spring 411 releases its elastic potential energy, pushing the inclined plate 409 outward. This causes the upper side of the inclined plate 409 to contact the lower side of the first push plate 401, thus fixing the insert plate 407. This allows the mounting box 402 to be installed above the first push plate 401. Then, the roller 406 is placed inside the U-shaped plate 13, pushing the first push plate 401 inward. This causes the roller 406 to move inward along the U-shaped plate 13, thereby installing the heat storage mechanism 4 inside the heat storage tank 14.

[0038] Multiple round holes 404 are made on the surface of the porous ceramic plate 403. After the porous ceramic plate 403 is pre-installed above the first push plate 401, it is pushed in as a whole. At this time, the silicon carbide rods 12 are inserted into the round holes 404 in sequence. Then the back plate 3 is closed, and hot air is generated by the external electric heater to circulate and heat the porous ceramic plate 403. At the same time, the silicon carbide rods 12 are energized so that the silicon carbide rods 12 generate heat energy to assist in heating the porous ceramic plate 403.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
