Description

Technical Field

[0001] This utility model relates to the field of heat storage electric heaters, specifically a heat storage electric heater insulation structure. Background Technology

[0002] A thermal storage electric heater is a heating device that uses stored electricity to provide heat. Its working principle is to convert electrical energy into heat energy and then store this heat using high-temperature resistant, low-thermal-conductivity insulation materials. Specifically, it uses heating elements to convert electrical energy into heat energy during off-peak hours at night and then stores this heat energy. During peak hours, the thermal storage electric heater releases the stored heat through radiation and convection, providing 24-hour indoor heating.

[0003] Existing thermal storage electric heaters typically require placing thermal storage bricks inside the heater during installation, followed by sealing with insulation cotton. However, during use and observation, it was found that there are large gaps in this insulation structure, resulting in poor insulation performance of the insulation cotton for the thermal storage bricks.

[0004] Therefore, a heat storage electric heater insulation structure is proposed to address the above problems. Utility Model Content

When the elastic clips enter the interior of the clamping plate, they will first contract, and when they are fully inside the clamping plate, they will recover under the action of elasticity. The pair of elastic bands will be fixed to the surface of the cover and the box body under the friction of the elastic clips and clamping plates. The cover will also be temporarily fixed under the squeezing action of the elastic bands, improving the stability of the cover installation and making it more convenient for the operator to install the cover. At the same time, the elastic bands will also squeeze the first sealing gasket and the second sealing gasket, so that the second sealing gasket and the first sealing gasket can further fill the gap between the cover and the box body under the squeezing action, improving the sealing performance when the cover and the box body are connected.

[0009] Preferably, a sponge is fixed to the middle of the elastic band; the sponge is located at the edge of the elastic band; when the worker's palms are sweaty, the sponge can be held in the palm to align the elastic clip and the clamping plate, increasing the friction between the palm and the elastic clip and clamping plate, and improving the convenience of operating the elastic clip and clamping plate.

[0010] Preferably, multiple Velcro straps are symmetrically fixed to the middle of the box body; the surface of the Velcro straps is provided with hooks; the surface of the elastic band is provided with rough edges; when the staff needs to remove the cover, the elastic clips and the retaining plate can be removed, and then the rough edges of the elastic band can be aligned with the hooks of the Velcro straps, so that the elastic band will be fixed to the surface of the box body under the friction of the rough edges and hooks, thereby improving the stability of the box body when placed.

[0011] Preferably, the bottom of the box is fixedly connected to multiple uprights; the bottom of each upright is fixedly connected to a protective pad; the protective pad is flexible; when the box is placed indoors for operation, the uprights and the protective pad will come into contact with the ground.

The box is equipped with a first insulation board 14 and insulation cotton 15. Workers can then place the heat storage brick inside the insulation cotton 15 and install the heating wire through the mounting hole 18. After installation, the second insulation board 17 and the groove 16 are aligned, and the cover 12 is installed on the surface of the box body 13. The second insulation board 17, once inside the groove 16, seals the gap between the cover 12 and the box body 13, as well as the surface of the insulation cotton 15, improving the sealing of the cavity inside the cover 12 and the box body 13, and enhancing the heat storage performance of the heat storage brick. Through the cooperation of the groove 16 and the second insulation board 17, the groove 16 seals the connection gap between the cover 12 and the box body 13 during installation, improving the sealing performance of the connection between the cover 12 and the box body 13, enhancing the heat storage performance of the heat storage brick inside the box body 13 during operation, and reducing heat loss.

[0025] Please see Figure 5 As shown, a first sealing gasket 2 is fixedly connected to the middle of the box body 13; a second sealing gasket 22 is fixedly connected to the middle of the cover 12; the surface of the second sealing gasket 22 is an arc-shaped structure; the second sealing gasket 22 and the first sealing gasket 2 are correspondingly arranged; after aligning the second insulation plate 17 and the groove 16, the cover 12 can be installed on the surface of the box body 13. The cover 12 will move towards the first sealing gasket 2 together with the second sealing gasket 22. The first sealing gasket 2 has a cavity inside. When the second sealing gasket 22 comes into contact with the first sealing gasket 2, it will deform under the pressure and enter the cavity inside the first sealing gasket 2. The second sealing gasket 22 will fill the cavity inside the first sealing gasket 2, making the connection between the cover 12 and the box body 13 tighter; through the cooperation of the first sealing gasket 2 and the second sealing gasket 22, when the cover 12 and the box body 13 are connected, the second sealing gasket 22 will be inserted into the cavity inside the first sealing gasket 2, further improving the sealing and heat preservation when the cover 12 and the box body 13 are connected.

[0026] Please see Figures 2 to 4As shown, multiple elastic bands 3 are symmetrically fixed to the middle of the box body 13; a pair of elastic clips 32 are fixed to one end of the elastic band 3 on one side; a retaining plate 33 is fixed to the other end of the elastic band 3 on the other side; the elastic clips 32 and retaining plates 33 are correspondingly arranged; when the operator installs the cover 12 on the surface of the box body 13, the cover 12 can be placed on the surface of the box body 13 and the elastic clips 32 and retaining plates 33 can be pulled to align them. When the elastic clips 32 enter the interior of the retaining plate 33, they will first contract, and when they are fully inside the retaining plate 33, they will return to their original position under the action of elastic force. The elastic band 3 will be fixed to the surface of the cover 12 and the box body 13 under the friction of the elastic clip 32 and the clamping plate 33. The cover 12 will also be temporarily fixed under the squeezing action of the elastic band 3, which improves the stability of the cover 12 during installation and makes it more convenient for the staff to install the cover 12. At the same time, the elastic band 3 will also squeeze the first sealing gasket 2 and the second sealing gasket 22, so that the second sealing gasket 22 and the first sealing gasket 2 can further fill the gap between the cover 12 and the box body 13 under the squeezing action, improving the sealing performance when the cover 12 and the box body 13 are connected.

[0027] See also Figure 4 As shown, a sponge 4 is fixed to the middle of the elastic band 3; the sponge 4 is located at the edge of the elastic band 3; when the worker's palms are sweaty, the sponge 4 can be held in the palm to align the elastic clip 32 and the clamping plate 33, increasing the friction between the palm and the elastic clip 32 and the clamping plate 33, and improving the ease of operation of the elastic clip 32 and the clamping plate 33.

[0028] See also Figure 5 As shown, multiple Velcro straps 5 are symmetrically fixed to the middle of the box body 13; the surface of the Velcro strap 5 is provided with a hook side; the surface of the elastic band 3 is provided with a rough side; when the staff needs to remove the cover 12, the elastic clip 32 and the clamping plate 33 can be removed, and then the rough side of the elastic band 3 can be aligned with the hook side of the Velcro strap 5, so that the elastic band 3 will be fixed to the surface of the box body 13 under the friction of the rough side and the hook side, thereby improving the stability of the box body 13 when it is placed.

[0029] See also Figure 2 As shown, multiple uprights 6 are fixed to the bottom of the box 1; a protective pad 62 is fixed to the bottom of the uprights 6; the protective pad 62 is flexibly designed; when the box 1 is placed indoors for operation, the uprights 6 and the protective pad 62 will come into contact with the ground. Because the protective pad 62 is flexibly designed, it will disperse the pressure applied to the ground surface when it comes into contact with the ground, reducing the damage to the ground caused by squeezing or friction.

[0030] See also Figure 2 As shown, the protective pad 62 has a frustum structure; because the protective pad 62 has a frustum structure, the contact area between the protective pad 62 and the ground is larger, which improves the protective effect of the protective pad 62 on the ground.

[0031] Working principle: During installation, the operator can open the box 1 and remove the cover 12 from the surface of the box 13. The inner wall of the box 13 is sequentially fitted with a first insulation board 14 and insulation cotton 15 from the inside out. Then, the operator can place the heat storage brick inside the insulation cotton 15 and install the heating wire through the mounting hole 18. After installation, the operator can align the second insulation board 17 and the groove 16 and then install the cover 12 on the surface of the box 13. The second insulation board 17, after entering the groove 16, will seal the gap between the cover 12 and the box 13, as well as the surface of the insulation cotton 15, improving the sealing of the cover 12 and the internal cavity of the box 13, and the heat storage brick's insulation performance. Aligning with the first insulation board 14 and the groove 16... After the second insulation board 17 and the groove 16 are installed, the cover 12 can be installed on the surface of the box body 13. The cover 12 will move towards the first sealing gasket 2 along with the second sealing gasket 22. The first sealing gasket 2 has a cavity inside. When the second sealing gasket 22 comes into contact with the first sealing gasket 2, it will deform under the pressure and enter the cavity inside the first sealing gasket 2. The second sealing gasket 22 will fill the cavity inside the first sealing gasket 2, making the connection between the cover 12 and the box body 13 tighter. When the operator installs the cover 12 on the surface of the box body 13, the cover 12 can be placed on the surface of the box body 13 and the elastic clip 32 and the clamping plate 33 can be pulled at the same time to align them. When clamp 32 enters the card plate 33, it will first contract. When it is fully inside the card plate 33, it will recover under the action of elastic force. A pair of elastic bands 3 will be fixed to the surface of the cover 12 and the box body 13 by the friction between the elastic clamp 32 and the card plate 33. The cover 12 will also be temporarily fixed by the compression of the elastic bands 3, improving the stability of the cover 12 during installation and making it more convenient for workers to install the cover 12. At the same time, the elastic bands 3 will also compress the first sealing gasket 2 and the second sealing gasket 22, so that the second sealing gasket 22 and the first sealing gasket 2 can further fill the gap between the cover 12 and the box body 13 under the compression. When the worker When the staff's palms are sweaty, they can hold the sponge 4 in their palms to align the elastic clip 32 and the card plate 33, increasing the friction between the palm and the elastic clip 32 and the card plate 33. When the staff needs to remove the cover 12, they can disassemble the elastic clip 32 and the card plate 33, and then align the rough side of the elastic band 3 with the hook side of the Velcro 5, so that the elastic band 3 will be fixed to the surface of the box 13 by the friction between the rough side and the hook side. When the box 1 is placed indoors for work, the upright 6 and the protective pad 62 will come into contact with the ground. Because the protective pad 62 is flexible, it will disperse the pressure applied to the ground surface when it comes into contact with the ground.
