Description

Technical Field

[0001] The present invention relates to an electric heater, and more particularly to an energy-saving electric heater. Background Art

[0002] There are many types of household electric heaters, and their working principles are basically similar. For commonly used electric heaters at present, such as oil radiators, their working principle is to heat the internal heat-conducting oil and then the heat is dissipated by each radiator. However, such electric heaters generally have the following problems:

[0003] First, the overall volume of the device is large and the height is relatively high. When in use, it is placed on the floor of the room, increasing the occupied area, affecting the passage in this area and the placement of other items. At the same time, when not in use, due to its large overall volume, it is not easy to store and put away.

[0004] Second, when such a device is used for heating, it is necessary to first heat the heat-conducting oil, and the heat distribution becomes more uniform through the heat-conducting oil. When the device is turned off after use, the temperature of the entire heat-conducting oil drops slowly. When used next time, it is necessary to re-heat the heat-conducting oil again. The starting temperature value is relatively low, and the heating time required is lengthened, and the power consumption will also increase accordingly.

[0005] Third, when such an electric heater is in use, the radiators are relatively fixed and cannot be adjusted relative to each other, resulting in a fixed and non-adjustable heat radiation direction during the use of the entire device, and the actual use cannot meet the use requirements in different environments. The heat radiation area is fixed, and there is no hot air flow assistance, resulting in an obvious decrease in the heating effect of the entire device after leaving the heat radiation area.

[0006] Fourth, similar electric heaters generally set up certain racks to achieve the purpose of drying clothes. However, after using the racks, the number of clothes that can be dried is limited, and some flat items cannot be dried. The types of items to be dried are very limited. Summary of the Invention

[0007] The technical problem to be solved by the present invention is an energy-saving electric heater, which uses a brand-new telescopic and flat-laying structure to effectively solve many problems existing in the prior art.

[0008] The present invention is achieved by the following technical solutions: an energy-saving electric heater, including a main body, a telescopic radiator, and a tail plate. The telescopic radiator is arranged between the main body and the tail plate, and both sides of the telescopic radiator are fixedly connected to the main body and the tail plate respectively;

[0009] The telescopic heat sink includes one or more heat sinks, each of which is provided with a heating element. The heating elements are connected in series via electrical cables and then connected to the host for control. The two sides of each heat sink are connected together via multiple elastic inflatable members, and a docking seal ring is protruded from the opposite side of each heat sink. The heat sink is located on one side of the docking seal ring as the heat dissipation surface.

[0010] When the elastic inflatable members are not inflated, the elastic rebound force of the elastic inflatable members is used to elastically press the heat sinks together. At this time, the adjacent heat sinks are butted together by butt sealing rings to seal the heat dissipation surface.

[0011] When the elastic inflatable members are inflated, the elastic inflatable members are used to open the heat sinks to separate the butt sealing rings and open the heat dissipation surfaces on both sides of the heat sinks.

[0012] As a preferred technical solution, the elastic inflatable parts all adopt hollow elastic rubber strips with elastic expansion and contraction capabilities, which are filled with gas to increase the overall length of the elastic inflatable parts. The elastic inflatable parts are inflated by a micro air pump set in the host.

[0013] As a preferred technical solution, the micro air pump is connected to the control motherboard in the host and powered by the control motherboard. It is turned on and off by the control motherboard. The air outlet of the micro air pump is provided with a multi-way interface. The output end of the multi-way interface is connected to a first connecting pipe and a second connecting pipe. The first connecting pipe is connected to each elastic inflatable member, and a first solenoid valve is provided on the end of the first connecting pipe close to the micro air pump, and a second solenoid valve is provided on the end of the second connecting pipe close to the micro air pump.

[0014] The output end of the second connecting pipe is connected to multiple gas regulating controls, which are respectively installed on both sides of the heat sink. The output end of the elastic inflatable part is provided with an exhaust pipe, and the exhaust pipe is installed with a third solenoid valve. The first solenoid valve, the second solenoid valve and the third solenoid valve are all connected to the control main board, and are controlled to open and close by the control main board. The multiple gas regulating controls are connected to each other through elastic connecting conduits.

[0015] As a preferred technical solution, a through assembly groove is provided on both sides of the heat sink corresponding to the position of the elastic inflatable parts. The elastic inflatable parts pass through the assembly grooves of each heat sink and are fixed with glue on the contact surface of the assembly grooves. There are also through heat conduction holes on both sides of the heat sink, and the gas adjustment control is installed in the heat conduction holes.

[0016] As a preferred technical solution, the gas control members each include a heat conduction tube and two air regulating discs. The air regulating discs are hollow inside, and an exhaust micro-hole is provided on the annular surface of each air regulating disc. A rotating shaft is provided on one side of each air regulating disc opposite to the heat conduction tube. The heat conduction tube is inserted into the heat conduction holes opened on both sides of the heat sink and seals the openings on both sides of the heat conduction holes. A gas conduction channel with openings on both sides is opened in the middle of the heat conduction tube. The air regulating discs are rotatably inserted into the gas conduction channel of the heat conduction tube through the rotating shafts, and a slightly convex sealing ring is provided on the outer wall surface of the rotating shaft. A sealing ring groove is provided in the gas conduction channel corresponding to the sealing ring. An elastic connecting conduit is connected to the air regulating discs of adjacent two gas control members.

[0017] As a preferred technical solution, a convex bulge is provided on each of the two heat dissipation surfaces of the heat sink. The heating elements inside the heat sink all adopt electric heating wires, and a heat-conducting copper layer is wrapped outside the electric heating wires. The hollow area inside the heat sink is filled with heat-conducting oil, and the heat-conducting oil is in contact with the outer wall surface of the heat conduction tube of the gas control member. The areas of each heat sink except the heat dissipation surface are all wrapped with a heat insulation and heat preservation layer.

[0018] As a preferred technical solution, a power bus is provided outside the main body, and a control panel is also provided at the position corresponding to the control main board on the main body. A plurality of control buttons are provided on the control panel.

[0019] As a preferred technical solution, a plurality of small suction cups are provided on the surfaces of the main body, the tail plate and the ground in contact with the ground, and rubber support pads are provided on the surfaces of each heat sink in contact with the ground.

[0020] As a preferred technical solution, a stretch spring section is provided on each electric connection wire. The electric connection wires connect the electric heating wires in series and are connected to the control main board through the electric connection wires.

[0021] The beneficial effects of the present invention are as follows: First, the present invention adopts a telescopic heat dissipation body. When not in use, by using the elastic contraction force of the elastic inflatable member, the heat sinks are butt-jointed and pressed tightly through the butt-joint sealing rings, and the distance between the heat sinks is reduced, making the volume of the entire device smaller. Therefore, it can be conveniently stored and carried when not in use.

[0022] Second, the present invention adopts a telescopic heat dissipation body structure. When in use, by inflating the elastic inflatable member to expand the heat sinks, the distance between the heat sinks is opened, thereby opening the heat sinks and exposing the heat dissipation surfaces. At this time, the entire structure is in a flat state, and people can step on it while wearing shoes without affecting the passage in this area. Moreover, some items to be dried, such as shoes, clothes, etc., can be placed on the flatly opened heat dissipation body. More items can be placed without affecting safety, and the use range is wider.

[0023] III. Since the present invention adopts a telescopic heat dissipation body structure, after it is turned off after use, the gas in the elastic inflatable member is released, and the elastic inflatable member is used to tighten each heat dissipation fin, so that the heat dissipation fins are butt-jointed and pressed tightly through the butt joint sealing ring. At this time, the heat dissipation surface of the heat dissipation fins is closed, and the heat transfer is blocked. At this time, each heat dissipation fin is in a continuous heat preservation state. When used next time, a higher basic temperature value can be obtained, the time and electric energy consumed for heating the initial temperature can be reduced, and more power can be saved.

[0024] IV. The present invention can also be placed vertically for use. When in use, the entire telescopic heat dissipation body can be bent so that the entire device is placed in an arc shape, and the size of the arc can be adjusted according to needs. Due to the setting of different arcs, the required heat radiation direction can be obtained, meeting the usage requirements in more scenarios.

[0025] V. The present invention is provided with a gas control member on the heating sheet. The gas ejected by the micro air pump passes through the heated heat conduction tube, and the gas temperature value can be increased. Then, through the air regulating disc that can be rotated and adjusted, the air outlet direction can be adjusted to the required one, so that the entire device can obtain the desired heat transfer direction, solving the problem of the single heat transfer direction of the traditional electric heater. Moreover, the hot gas source utilizes the gas source of the micro air pump, simplifying the structure while obtaining a heat outlet method with adjustable direction.

[0038] All features disclosed in this specification, or all steps in the disclosed methods or processes, except for mutually exclusive features and / or steps, can be combined in any way.

[0039] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless specifically stated, can be replaced by other equivalent or similar-purpose alternative features. That is, unless specifically stated, each feature is only an example of a series of equivalent or similar features.

[0040] As Figure 1 shown, an energy-saving electric heater of the present invention includes a main body 1, a telescopic heat dissipation body 4 and a tail plate 2. The telescopic heat dissipation body 4 is arranged between the main body 1 and the tail plate 2, and both sides of the telescopic heat dissipation body 4 are fixedly connected to the main body 1 and the tail plate 2 respectively;

[0041] The telescopic heat dissipation body 4 includes more than one heat sink 41. Each heat sink 41 is provided with a heating element. Each heating element is connected in series with each other through an electric connection wire 16 and then connected to the main body 1 for control. Both sides of each heat sink 41 are connected together through a plurality of elastic inflatable members 14, and a docking sealing ring 42 is protrudingly arranged on the opposite surface of each heat sink 41. The side of the heat sink 41 where the docking sealing ring 42 is located is the heat dissipation surface 44;

[0042] When each elastic inflatable member 14 is not inflated, the elastic resilience of the elastic inflatable member 14 is used to elastically press the heat sinks 41 against each other. At this time, the adjacent heat sinks 41 are docked through the docking sealing ring 42 and the heat dissipation surface 44 is closed, as Figure 1 shown;

[0043] After the elastic inflatable members 14 are inflated, the elastic inflatable members 14 are used to open the heat sinks 41 to separate the docking seal rings 42 and open the heat dissipation surfaces 44 on both sides of the heat sink 41. Figure 2 and Figure 6 shown.

[0044] Among them, the elastic inflatable parts 14 all adopt hollow elastic rubber strips with elastic expansion and contraction capabilities. After filling with gas, the overall length of the elastic inflatable parts is increased. The elastic inflatable parts 14 are inflated by a micro air pump 8 arranged in the main unit. After inflation, the elastic inflatable parts 14 expand and then stretch out the adjacent heat sinks 41, so that the distance between the heat sinks 41 is increased, and the opening for use is achieved.

[0045] like Figure 4 and Figure 5 As shown, the micro air pump 8 is connected to the control motherboard in the host 1 and powered by the control motherboard. It is turned on and off by the control motherboard. The outlet end of the micro air pump 8 is provided with a multi-way interface 9. The output end of the multi-way interface 9 is connected to a first connecting pipe 11 and a second connecting pipe 12. The first connecting pipe 11 is connected to each elastic inflatable member 14. A first solenoid valve 24 is provided on the end of the first connecting pipe 11 near the micro air pump 8, and a second solenoid valve 25 is provided on the end of the second connecting pipe 12 near the micro air pump 8.

[0046] The output end of the second connecting pipe 12 is connected to multiple gas regulating controls 5, which are respectively installed on both sides of the heat sink 41. The output end of the elastic inflatable member 14 is provided with an exhaust pipe 15, and the exhaust pipe 15 is installed with a third solenoid valve (not shown). The first solenoid valve 24, the second solenoid valve 25 and the third solenoid valve are all connected to the control main board and are controlled to open and close by the control main board. The multiple gas regulating controls are interconnected through elastic connecting conduits.

[0047] like Figure 9 As shown, a through assembly groove 23 is provided on both sides of the heat sink 41 at the position corresponding to the elastic inflatable member. The elastic inflatable member 14 passes through the assembly groove 23 of each heat sink 41 and is fixed with glue on the contact surface of the assembly groove 23. A through heat conduction hole (not shown) is also provided on both sides of the heat sink 41, and the gas adjustment control 5 is installed in the heat conduction hole.

[0048] like Figure 3 and Figure 10As shown in the figure, the gas control member 5 includes a heat conducting pipe 55 and two gas regulating discs 51. The inside of the gas regulating disc 51 is hollow, and an exhaust micropore 52 is provided on the annular surface of the gas regulating disc. A rotating shaft 53 is provided on one side of the gas regulating disc 51 opposite to the heat conducting pipe 55. The heat conducting pipe 55 is inserted into the heat conducting holes opened on both sides of the heat sink fins and seals the openings on both sides of the heat conducting holes. A gas guiding channel with openings on both sides is opened in the middle of the heat conducting pipe 55. The gas regulating disc 51 is rotatably inserted into the gas guiding channel of the heat conducting pipe 55 through the rotating shaft 53, and a slightly convex sealing ring 54 is provided on the outer wall surface of the rotating shaft. A sealing ring groove (not shown) is provided in the gas guiding channel corresponding to the sealing ring 54. The elastic connecting conduit 56 is connected to the gas regulating discs 51 of two adjacent gas control members. By providing the sealing ring 54, the sealing performance between the rotating shaft 53 and the heat conducting pipe 55 is increased to prevent air leakage. The heat conducting pipe 55 is inserted into the heat conducting hole and fixed and sealed with glue. The heat of the heat conducting oil will be transferred to the heat conducting pipe. When the gas enters the gas regulating disc and is transferred from the heat conducting pipe to another gas regulating disc, the gas will pass through the rotating shaft and the heat conducting pipe and heat up. Finally, the excess gas will be discharged from the exhaust micropore. Since the gas regulating disc can rotate relative to the heat conducting pipe by an angle, the entire gas regulating disc can rotate by an angle to adjust the exhaust direction of the exhaust micropore, achieving the purpose of adjustable exhaust direction.

[0049] As Figures 7 - 9 shown, a convex bump 43 is provided on each of the two heat dissipating surfaces of the heat sink fins 41. The heating elements inside the heat sink fins 41 all adopt electric heating wires 21. A heat conducting copper layer is wrapped outside the electric heating wires 21. The hollow area inside the heat sink fins is filled with heat conducting oil. The heat conducting oil is in contact with the outer wall surface of the heat conducting pipe of the gas control member. The areas of each heat sink fin except the heat dissipating surface are all wrapped with a heat insulating and heat preserving layer (not shown). The electric heating wire 21 is used to heat the heat conducting copper layer, and the heat conducting copper layer is used to heat the heat conducting oil and raise the temperature of the heat sink fins. Since the heat insulating and heat preserving layer is wrapped on the positions of the heat sink fins except the heat dissipating surface, heat dissipation will only occur from the heat dissipating surface. In this embodiment, the heat insulating and heat preserving layer can be made of heat insulating rubber material.

[0050] Among them, as Figure 1 shown, a power bus 3 is provided outside the main unit 1, and a control panel is also provided at the position corresponding to the control main board on the main unit. A plurality of control buttons 6 are provided on the control panel. The control buttons 6 can be a power on / off button, a solenoid valve control button, a temperature knob control button, a micro air pump control button, etc.

[0051] To ensure positioning when placed horizontally or vertically, multiple small suction cups 7 are installed on the ground contact surface of the main unit and tailboard. Rubber support pads (not shown) are installed on the ground contact surface of each heat sink. The rubber support pads are used to provide bottom support for each heat sink, and multiple small suction cups are used to absorb and position the main unit and tailboard to prevent tipping and random displacement. To increase the support stability of each heat sink when placed horizontally, in this embodiment, the height of the heat sink is reduced accordingly, and a widened portion is provided at the bottom, so that the heat sink is in a "T" shape. Figure 8 As shown, as the height of the heat sink is reduced, the bearing capacity of the top thereof will increase accordingly. When a person steps on the upper end, it has a better bearing capacity, and the T-shaped structure makes it more stable when stepping over.

[0052] Among them, each electrical connection line 16 is provided with a stretching spring section, and the electrical connection line 16 connects each electric heating wire in series, and is connected to the control main board by the electrical connection line. Since the electrical connection line between each electric heating wire is provided with a stretching spring section, when the heat sink is stretched, it can be pulled without being affected by the length of the electrical connection line.

[0053] like Figure 11 As shown, the entire structure of the present invention can be set up vertically. In this case, the small suction cups at the bottom of the main engine and the tail plate adsorb the bottom surface and adjust the curvature of the middle telescopic heat sink, such as Figure 11 As shown by the middle arrow, the telescopic heat sink can be set into an arc shape, and then the main engine and the tail plate are fixed at both ends. The whole structure is in a "C" shape. Since the structure between the heat sinks is set as an elastic inflatable part, when the elastic inflatable part is inflated to open the heat sink, the size of the arc can be adjusted. The size of the arc can be selected according to actual needs, thereby controlling the direction and range of heat radiation, and the arc placement can be more stable.

[0054] When used horizontally, it is necessary to turn on the machine first, then adjust the temperature, open the first solenoid valve, close the second solenoid valve and the third solenoid valve, and turn on the micro air pump. At this time, the gas is inflated into each elastic inflatable part through the first connecting pipe, so that each elastic inflatable part expands after being inflated, and then the heat sinks are stretched open. Figure 2 and Figure 3As shown, the expansion size depends on the user. The more gas is filled, the larger the expansion, the larger the spacing between the heat sinks, and vice versa. After adjusting the clearance value of the heat sinks, the heat dissipation surface is conducted. At this time, heating is carried out to achieve the purpose of heating and obtaining heat. The first solenoid valve is closed, and the third solenoid valve is kept closed. At this time, the second solenoid valve is manually opened, and the inflation speed of the micro air pump is adjusted. At this time, gas is filled into each gas control part through the second connecting pipe. Since each gas control part is connected and conducted through an elastic connecting conduit, part of the continuously filled gas is discharged from the exhaust micropores, and the rest is transferred to the next gas control part, so as to realize the exhaust structure led out by the exhaust micropores, so as to supplement and control the hot air gas source direction. After use, if it is necessary to turn off the heating, only need to open the third solenoid valve to discharge the gas in the elastic inflatable part. At this time, the elastic inflatable part uses the elastic resilience to reset each heat sink, and the docking sealing ring between the heat sinks is docked and sealed. The entire convex package and other heat dissipation surfaces are sealed off. At this time, the heat dissipation surface does not contact the external air, achieving a good heat preservation purpose. When using it next time, a higher basic temperature value can be obtained, reducing the time consumed for heating up and saving a large amount of electric energy.

[0055] The beneficial effects of the present invention are as follows: First, the present invention adopts a telescopic heat dissipation body. When not in use, the elastic contraction force of the elastic inflatable part is used to make the heat sinks dock and press tightly through the docking sealing ring, and the distance between the heat sinks is reduced, and the volume of the entire device becomes smaller. Therefore, it can be conveniently stored and carried when not in use;

[0056] Second, the present invention adopts a telescopic heat dissipation body structure. When in use, the elastic inflatable part is inflated to expand each heat sink, so that the distance between the heat sinks is widened, and then the heat sinks are opened to expose the heat dissipation surface. At this time, the entire structure is in a flat state, and the upper end can be stepped on and walked on when wearing shoes, without affecting the passage of this area, and some items to be dried, such as shoes, clothes, etc., can be placed on the flatly opened heat dissipation body. More items can be placed without affecting safety, and the use range is wider;

[0057] Third, since the present invention adopts a telescopic heat dissipation body structure, after use and closing, the gas in the elastic inflatable part is discharged, and the elastic inflatable part is used to tighten each heat sink, so that the heat sinks are docked and pressed tightly through the docking sealing ring. At this time, the heat dissipation surface of the heat sink is closed, blocking the heat transfer. At this time, each heat sink is in a continuous heat preservation state. When using it next time, a higher basic temperature value can be obtained, reducing the time and electric energy consumed for initial temperature heating, and being more power-saving;

[0058] IV. The present invention can also be used in a vertical position. When in use, the entire telescopic radiator can be bent so that the entire device is placed in an arc shape, and the size of the arc can be adjusted as needed. By setting different arcs, the required heat radiation direction can be obtained, meeting the usage requirements in more scenarios;

[0059] V. The present invention is provided with a gas control member on the heating sheet. The gas ejected by the micro air pump passes through the heated heat conduction tube, and the gas temperature value can be increased. Then, through the gas adjustment disk that can be rotated and adjusted, the gas is adjusted to the required outlet direction, so that the entire device can obtain the desired heat transfer direction, solving the problem of the single heat transfer direction of traditional electric heaters. Moreover, this hot gas source utilizes the gas source of the micro air pump, simplifying the structure while obtaining a heat outlet method with adjustable direction.

[0060] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any change or replacement that can be thought of without creative work should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
