Description

Technical Field

[0001] The present invention relates to the technical field of electric heaters, and in particular to a phase-change heat storage electric heater. Background Art

[0002] Phase change heat storage electric heater is an electric heater that uses phase change material as the heat storage medium. It mainly stores heat in the form of latent heat. The heat storage capacity is large (3-8 times that of the same volume of water), and the heat release temperature fluctuation is small. The working process mainly includes heating: adopting the working mode of interaction between convection and circulation; phase change: after power is turned on and heated, the polymer substance will be activated, changing from liquid to gas, and forming an internal cycle, the temperature will rise rapidly, causing the surface temperature of the heater to rise rapidly, reaching the set temperature and automatically cutting off the power; heat storage: after power is cut off, the energy storage minerals release heat, causing the temperature to drop slowly; circulation: when the temperature gradually drops to the set start temperature, the heating is started again.

[0003] The working process of the existing phase change heat storage electric heater is to heat first, then store heat, and finally circulate heating. When the residents need to temporarily leave the room equipped with the phase change heat storage electric heater, if the electric heater only stores heat, the heat will gradually dissipate. If it is turned off directly, it will take more electricity and time to start again. If the electric heater repeats the above process, the electric heater will continue to work and consume electricity during the time when the residents are away. Therefore, the current phase change heat storage electric heater needs to have a temporary and efficient heat insulation function. For this purpose, a phase change heat storage electric heater is proposed. Summary of the invention

[0021] 3. The present invention provides a sealing pressure rod, so that when the sealing plate moves to the inside of the driving box, the two sealing pressure rods located on the top of the sealing plate will move to the two sides of the two driving rods along with the movement of the two sealing plates, until the two driving rods after being combined are stuck in the sealing buckle grooves on one side of the two sealing pressure rods, so that the sealing pressure rod covers the gap between the two driving rods, reducing the dissipation of heat and further improving the heat insulation effect;

The two side wing plates 3 are fixedly installed on the top of the electric heater base 1, and heat dissipation holes are opened on the side walls of the side wing plates 3. The inside of the heat dissipation holes are driven to install a plurality of horizontally arranged movable heat dissipation plates 4. The plurality of movable heat dissipation plates 4 are evenly distributed from top to bottom and are adapted to the heat dissipation holes. In this embodiment, the plurality of movable heat dissipation plates 4 in the heat dissipation holes are all controlled in linkage through a transmission motor and a gear transmission system, and a driving box 5 is arranged on the other two sides of the phase change heat storage electric heater body 2. The two driving boxes 5 are fixedly installed between the two side wing plates 3, and the two side wing plates 3 are close to each other. The two sides of the phase-change heat storage electric heater are fixedly installed with a heat-insulating folding cloth cover 6, and the two ends of the heat-insulating folding cloth cover 6 extend to the inside of the two drive boxes 5 respectively. The drive boxes 5 are provided with heat-insulating drive components. In this embodiment, the phase-change heat storage electric heater can provide a variety of control methods, including but not limited to remote control by a dedicated simple remote control, an APP on a smart terminal such as a mobile phone, or direct control by a button on the electric heater; specifically, when the phase-change heat storage electric heater is in use, if the resident needs to leave temporarily, the phase-change heat storage electric heater body 2 can be controlled by a remote control, a smart terminal or a button on the phase-change heat storage electric heater to directly store heat;

[0043] The heat insulation driving component is used to drive the heat insulation folding cloth covers 6 on both sides to stretch and cover the electric heater base 1 inside when the phase change heat storage electric heater body 2 stores heat;

[0044] like Figure 3 As shown, the heat-insulating drive assembly includes four electric guide rails 8 respectively fixedly mounted on the inner walls of two drive boxes 5. Figure 4 As shown, the four electric guide rails 8 are symmetrically distributed. Figure 5 As shown, an electric slide 9 is driven and installed on one side of the electric guide rail 8, and a movable bracket 10 is fixedly installed on the side wall of the electric slide 9. Figure 2 As shown, the two heat-insulating folding cloth covers 6 are fixedly mounted with a driving rod 7 on one side close to each other. In this embodiment, the heat-insulating folding cloth covers 6 and the driving rod 7 are both inverted "U" shapes, and the two ends of the driving rod 7 are respectively slidably mounted inside the two driving boxes 5. Figure 5 As shown, the two ends of the two driving rods 7 are fixedly connected to the four movable brackets 10 respectively; specifically, by setting a heat insulation driving component, after the phase change heat storage electric heater body 2 starts to store heat, the two electric guide rails 8 on the same side will respectively drive the two electric slides 9 to move in the opposite direction, and then the four electric slides 9 will respectively drive the bottom ends of the two driving rods 7 to move laterally through the movable brackets 10, so that the two driving rods 7 drive the heat insulation folding cloth cover 6 to extend, until the two driving rods 7 merge, so that the phase change heat storage electric heater body 2 is completely covered by the two heat insulation folding cloth covers 6, and at the same time The multiple movable heat sinks 4 on both sides rotate downward to close the heat dissipation holes, so that the heat-insulating folding cloth cover 6 can insulate the internal phase-change heat storage electric heater body 2, greatly reducing the heat loss of the phase-change heat storage electric heater body 2 in the heat storage state. When the resident comes back, the heat-insulating folding cloth covers 6 on both sides can be controlled to fold, and the movable heat sinks 4 can be flipped upward again to connect the heat dissipation holes. At this time, the phase-change heat storage electric heater body 2 will restore the heat dissipation and heating effect, so that the phase-change heat storage electric heater does not need to be turned off or repeatedly heated when the resident temporarily leaves, reducing heat loss and power consumption;

[0045] The top of the driving box 5 is provided with a sealing driving assembly for sealing the two combined heat-insulating folding cloth covers 6;

[0046] like Figure 1 As shown, the sealing drive assembly includes a telescopic box 11 fixedly mounted on one side of the drive box 5, as shown in FIG. Figure 6 As shown, a vertically arranged lifting electric push rod 12 is fixedly installed inside the telescopic box 11. Figure 8As shown, the telescopic end of the lifting electric push rod 12 is fixedly installed with a horizontally arranged transverse electric push rod 13, the telescopic end of the transverse electric push rod 13 faces the phase change heat storage electric heater body 2 and is fixedly installed with a push frame 15, and the bottom of the push frame 15 is fixedly installed with a horizontally arranged sealing plate 14, the sealing plate 14 is adapted to the movable heat dissipation plate 4, and the sealing plate 14 is provided with a card groove 1401 adapted to the drive rod 7 on the side facing the phase change heat storage electric heater body 2; specifically, by setting a sealing drive component, after the two drive rods 7 are combined, the transverse electric push rods 13 on one side of the two drive boxes 5 will pass through the push frame 15 drives the sealing plate 14 to move toward the phase change heat storage electric heater body 2 until the two sealing plates 14 are respectively located directly above the two drive boxes 5 and contact the heat insulation folding cloth cover 6 and the drive rod 7, and then the lifting electric push rod 12 drives the transverse electric push rod 13 to move downward, thereby driving the two sealing plates 14 to descend to the inside of the drive box 5 to seal the drive box 5, and at the same time, the sealing plate 14 uses the card slot 1401 to lock the two heat insulation folding cloth covers 6, and greatly reduces the gap between the heat insulation folding cloth cover 6 and the movable heat sink 4, thereby improving the sealing of the space where the phase change heat storage electric heater body 2 is located and improving the heat insulation effect.

[0047] like Figure 7 As shown, a sealing rod 16 is fixedly installed on the top of the sealing plate 14. In this embodiment, the sealing rod 16 is L-shaped, and the two sealing rods 16 are symmetrically arranged. Figure 8 As shown, the sealing pressure rod 16 is provided with a sealing buckle groove 1601 matched with the driving rod 7 on one side of the phase change heat storage electric heater body 2; specifically, by setting the sealing pressure rod 16, when the sealing plate 14 moves to the inside of the driving box 5, the two sealing pressure rods 16 located on the top of the sealing plate 14 will move to the two sides of the two driving rods 7 with the movement of the two sealing plates 14, until the two merged driving rods 7 are stuck in the sealing buckle groove 1601 on one side of the two sealing pressure rods 16, so that the sealing pressure rod 16 covers the gap between the two driving rods 7, reduces heat dissipation, and further improves the heat insulation effect.

[0048] like Fig. 9 As shown, a plurality of evenly distributed clothes-drying strips 17 are fixedly installed on the top of the two sealing pressure rods 16 close to each other; specifically, by setting the clothes-drying strips 17, the plurality of clothes-drying strips 17 divide the top of the sealing pressure rod 16 into multiple areas, so that when the phase change heat storage electric heater body 2 is working normally, small pieces of clothing can be hung on the top of the sealing pressure rod 16 for drying, and the heating effect of the phase change heat storage electric heater body 2 can be used to dry the clothing.

[0049] like Fig. 9As shown, reinforcing tripods 18 are provided on both sides of the top bend of the sealing pressure rod 16, and three corresponding assembly holes are opened on the side walls of the reinforcing tripod 18 and the sealing pressure rod 16, and the same reinforcing bolt group 19 is provided on the three assembly holes located at the same place; specifically, by providing the reinforcing tripod 18, the reinforcing tripods 18 on both sides of the bend of the sealing pressure rod 16 are screwed with the reinforcing bolt groups 19 in the three groups of assembly holes, and the positioning triangle plates 21 are respectively assembled on both sides of the sealing pressure rod 16, so that the reinforcing tripod 18 can enhance the structural strength of the bend of the sealing pressure rod 16, thereby preventing the sealing pressure rod 16 from being deformed or broken due to excessive or heavy foreign objects drying on the sealing pressure rod 16.

[0050] like Fig. 9 As shown, a clothes-drying rod 20 is provided on the side facing away from each other at the top of the two sealing pressure rods 16, and a positioning triangle plate 21 is fixedly installed on both sides of the end of the clothes-drying rod 20 close to the sealing pressure rod 16, and the two positioning triangle plates 21 are located on both sides of the sealing pressure rod 16, and two positioning holes are provided on the positioning triangle plates 21, and the positioning holes are adapted to the reinforcing bolt groups 19, wherein the two reinforcing bolt groups 19 are respectively located inside the four positioning holes; specifically, by providing the clothes-drying rod 20, the clothes-drying rod 20 is connected to the sealing pressure rod 16 through the two reinforcing bolt groups 19 and the two positioning holes. , the assembly holes on the reinforced tripod 18 are screwed so that the two positioning triangles 21 are respectively fixed on one side of the two reinforced tripods 18, so that the clothes drying rod 20 is installed on one side of the sealing pressure rod 16, which increases the clothes drying space and facilitates the drying of large clothes. At the same time, when the clothes drying rod 20 is not needed, the reinforcing bolt group 19 can be unscrewed to directly remove the clothes drying rod 20, or the clothes drying rod 20 can be rotated downward ninety degrees and re-screwed on the sealing pressure rod 16, so that one end of the clothes drying rod 20 hangs down on one side of the sealing pressure rod 16, reducing the space occupied by the clothes drying rod 20.

[0051] like Fig. 9 As shown, a plurality of evenly distributed clothes-drying holes 2001 are provided on the top of the clothes-drying rod 20, and an anti-collision rubber sleeve 22 is fixedly sleeved on one end of the clothes-drying rod 20 away from the sealing pressure rod 16; specifically, by providing the clothes-drying holes 2001, the clothes-drying holes 2001 can facilitate the hanging of the clothes-drying rack and prevent clothes from falling from the clothes-drying rod 20. At the same time, the anti-collision rubber sleeve 22 at one end of the clothes-drying rod 20 can reduce the damage to the residents caused by the clothes-drying rod 20 when the residents collide with the phase change heat storage electric heater.

[0052] like Figure 2As shown, a micro-vacuum pump 23 is fixedly installed on one side of one of the side wing panels 3. In the present embodiment, an air inlet end of the micro-vacuum pump 23 passes through the side wing panel 3, and an exhaust pipe 24 is fixedly installed on the air outlet end of the micro-vacuum pump 23. The exhaust pipe 24 is arranged downwardly at one end away from the micro-vacuum pump 23. Specifically, by arranging the micro-vacuum pump 23, when the phase-change heat storage electric heater body 2 stores heat, the heat-insulating folding cloth covers 6 on both sides are combined to insulate the phase-change heat storage electric heater body 2. At this time, the micro-vacuum pump 23 on one side will extract the air inside the space surrounded by the heat-insulating folding cloth cover 6, the electric heater base 1, and the side wing panel 3 and discharge it to the outside, thereby reducing the air content in the space around the phase-change heat storage electric heater body 2, greatly slowing down the speed at which the phase-change heat storage electric heater body 2 transfers heat to the external environment, and improving the heat insulation effect. At the same time, the exhaust pipe 24 arranged downwardly can prevent the concentrated and high-speed moving warm gas from burning the residents' skin when the micro-vacuum pump 23 is exhausted to the outside.

[0053] like Figure 2 As shown, an air intake solenoid valve 25 is fixedly installed on one side of one of the side wing plates 3. In the present embodiment, the exhaust end of the air intake solenoid valve 25 passes through the side wing plate 3. Specifically, by setting the air intake solenoid valve 25, before the heat insulation function of the heat insulation folding cloth cover 6 on the phase change heat storage electric heater body 2 is released, the air intake solenoid valve 25 on one side of the phase change heat storage electric heater body 2 will be opened first, so that the external air will flow into the inside through the air intake solenoid valve 25, thereby balancing the air pressure of the internal space covered by the heat insulation folding cloth cover 6 and the external environment, avoiding excessive pressure difference between the internal and external spaces, resulting in excessive burden on the heat insulation drive assembly and the sealing drive assembly when they are reset, and at the same time, the heat insulation folding cloth cover 6 that was originally concave inward due to the action of air pressure is restored to its shape.

[0054] In summary: when the phase-change heat storage electric heater is in use, if the resident needs to leave temporarily, the phase-change heat storage electric heater body 2 can be controlled by a remote control, an intelligent terminal or a button on the phase-change heat storage electric heater to directly store heat. By setting a heat insulation driving component, after the phase-change heat storage electric heater body 2 starts to store heat, the two electric guide rails 8 on the same side will respectively drive the two electric slides 9 to move in the opposite direction, and then the four electric slides 9 will respectively drive the bottom ends of the two driving rods 7 to move laterally through the movable bracket 10, so that the two driving rods 7 drive the heat insulation folding cloth cover 6 to extend until the two driving rods 7 merge, so that the phase-change heat storage electric heater body 2 is completely covered by the two heat insulation folding cloth covers 6, and at the same time, the multiple movable heat dissipation plates 4 on both sides rotate downward, The heat dissipation holes are closed, so that the heat-insulating folding cloth cover 6 can insulate the internal phase-change heat storage electric heater body 2, greatly reducing the heat loss of the phase-change heat storage electric heater body 2 in the heat storage state. When the residents come back, the heat-insulating folding cloth covers 6 on both sides can be controlled to fold, and the movable heat dissipation plates 4 can be flipped upward again to connect the heat dissipation holes. At this time, the phase-change heat storage electric heater body 2 will restore the heat dissipation and heating effect, so that the phase-change heat storage electric heater does not need to be turned off or repeatedly heated when the residents temporarily leave, reducing heat loss and electricity consumption. By setting a sealing drive component, after the two drive rods 7 are combined, the transverse electric push rods 13 on one side of the two drive boxes 5 will drive the sealing plate 14 to move toward the phase-change heat storage electric heater body 2 through the push frame 15. Until the two sealing plates 14 are respectively located above the two driving boxes 5 and contact the heat-insulating folding cloth cover 6 and the driving rod 7, then the lifting electric push rod 12 drives the transverse electric push rod 13 to move downward, thereby driving the two sealing plates 14 to descend to the inside of the driving box 5 to seal the driving box 5, and at the same time, the sealing plate 14 uses the card slot 1401 to lock the two heat-insulating folding cloth covers 6, and greatly reduces the gap between the heat-insulating folding cloth cover 6 and the movable heat dissipation plate 4, thereby improving the sealing of the space where the phase change heat storage electric heater body 2 is located, and improving the heat insulation effect, by arranging the sealing pressure rod 16, when the sealing plate 14 moves to the inside of the driving box 5, the two sealing pressure rods 16 located on the top of the sealing plate 14 will move to the two driving rods with the movement of the two sealing plates 14 7, until the two driving rods 7 after merging are stuck in the sealing buckle groove 1601 on one side of the two sealing pressure rods 16, so that the sealing pressure rod 16 covers the gap between the two driving rods 7, reduces the heat dissipation, and further improves the heat insulation effect. By setting the clothes-drying clip 17, multiple clothes-drying clips 17 divide the top of the sealing pressure rod 16 into multiple areas, which is convenient for hanging small pieces of clothing on the top of the sealing pressure rod 16 for drying when the phase-change heat storage electric heater body 2 is working normally, and the heating effect of the phase-change heat storage electric heater body 2 is used to dry the clothes. By setting the reinforcing tripod 18, the reinforcing tripods 18 on both sides of the bending part of the sealing pressure rod 16 are screwed with the reinforcing bolt group 19 in the three groups of assembly holes.The positioning triangle plates 21 are respectively assembled on both sides of the sealing pressure rod 16, so that the reinforcing triangle frame 18 can enhance the structural strength of the bending part of the sealing pressure rod 16, so as to prevent the sealing pressure rod 16 from being deformed or broken due to excessive or heavy foreign objects being hung on the sealing pressure rod 16. By arranging the clothes drying rod 20, the clothes drying rod 20 is screwed with the assembly holes on the sealing pressure rod 16 and the reinforcing triangle frame 18 through two reinforcing bolt groups 19 and two positioning holes, so that the two positioning triangle plates 21 are respectively fixed on one side of the two reinforcing triangle frames 18, so that the clothes drying rod 20 is installed in the sealing pressure rod 16. One side of the sealing pressure rod 16 serves to increase the clothes-drying space, making it convenient to dry large clothes. At the same time, when the clothes-drying rod 20 is not needed, the reinforcing bolt group 19 can be unscrewed to directly remove the clothes-drying rod 20, or the clothes-drying rod 20 can be rotated downward by 90 degrees and re-screwed on the sealing pressure rod 16, so that one end of the clothes-drying rod 20 hangs down on one side of the sealing pressure rod 16, reducing the space occupied by the clothes-drying rod 20. By setting the clothes-drying hole 2001, the clothes-drying hole 2001 can facilitate the hanging of the clothes-drying rack to prevent clothes from falling from the clothes-drying rod 20. At the same time, the anti-collision rubber sleeve at one end of the clothes-drying rod 20 22 can reduce the damage of the clothes drying rod 20 to the residents when the residents collide with the phase change heat storage electric heater. By setting the micro vacuum pump 23, when the phase change heat storage electric heater body 2 stores heat, the heat insulation folding cloth covers 6 on both sides are combined to insulate the phase change heat storage electric heater body 2. At this time, the micro vacuum pump 23 on one side will extract the air inside the space surrounded by the heat insulation folding cloth cover 6 and the electric heater base 1 and the side wing plate 3 and discharge it to the outside, thereby reducing the air content in the space around the phase change heat storage electric heater body 2, and greatly delaying the phase change heat storage electric heater body 2 from transferring heat to the external environment. The speed of the amount is increased to improve the heat insulation effect. By setting the air intake solenoid valve 25, before releasing the heat insulation function of the heat insulation folding cloth cover 6 on the phase change heat storage electric heater body 2, the air intake solenoid valve 25 on one side of the phase change heat storage electric heater body 2 will be opened first, so that the external air will flow into the interior through the air intake solenoid valve 25, thereby balancing the air pressure of the internal space covered by the heat insulation folding cloth cover 6 and the external environment, avoiding excessive pressure difference between the internal and external spaces, which will cause excessive burden on the heat insulation drive component and the sealing drive component when resetting, and at the same time, the heat insulation folding cloth cover 6, which was originally concave inward due to the air pressure, can be restored to its shape.
