[0002] An electric heater is a product that can convert electrical energy into thermal energy; it has the advantages of being inexpensive, good quality, and easy to use.

[0003] When heating in winter, the air in the room is relatively dry, which affects the breathing and skin surface of people indoors.

[0004] like Figure 1 As shown, the existing electric oil heater products are equipped with a humidifier box 2 accessory. The purpose is that when using the product, the humidifier box 2 filled with water can be placed on the radiator body of the electric oil heater 1, and the temperature of the radiator body surface can be used to slowly evaporate the water in the humidifier box to achieve the purpose of humidifying the air, thereby alleviating the problem of dry air in the heating room.

[0005] Since the surface temperature of the tumble dryer cannot exceed a predetermined limit (e.g., 85K), the humidification effect of the humidification box placed on the surface of the tumble dryer is limited. In addition, the humidification box is placed on the top surface of the tumble dryer, which may cause it to fall off easily and be inconvenient to store. Summary of the invention

[0006] The main purpose of the present invention is to provide an electric heater which has both scalding prevention effect and better humidification effect.

[0007] In order to achieve the above-mentioned purpose, the present invention provides an electric heater, which includes: an electric heater body; an insulating part, which is connected to the outer wall surface of the electric heater body to form an insulating cavity together with the outer wall surface of the electric heater body; wherein, the insulating part is provided with a through hole connected to the insulating cavity, so that liquid can be injected into the insulating cavity through the through hole, and water vapor formed by the liquid in the insulating cavity being evaporated by heat is discharged through the through hole.

[0008] Furthermore, at least one through-hole unit is provided on the heat-insulating portion, and the through-hole unit includes at least one through-hole.

[0009] Furthermore, grooves are arranged on the heat insulation part, and each through-hole unit corresponds to one groove; and the through-hole of each through-hole unit is opened on the bottom wall of the corresponding groove.

[0010] Furthermore, the through hole is opened on the top of the heat insulation part.

[0011] Furthermore, a drain port connected to the insulation cavity is provided on the insulation part, so that the liquid in the insulation cavity can be discharged through the drain port; a plugging piece is provided at the drain port, and the plugging piece is detachably provided.

[0012] Furthermore, the drain port is opened at the bottom of the heat insulation part.

[0013] Furthermore, a edging structure is provided at the connection between the heat insulating part and the electric heater body, and the edging structure is used to wrap the connection between the heat insulating part and the electric heater body.

[0014] Furthermore, the main body of the electric heater is an oil-heating heater, and the insulation part is used to be connected to the rear heat sink of the oil-heating heater to form an insulation cavity with the rear heat sink of the oil-heating heater.

[0015] Furthermore, a edging structure is provided at the connection between the heat insulation part and the tail heat sink, and the edging structure wraps around the outer peripheral edge of the tail heat sink, and the edging structure and the heat insulation part are an integrated structure.

[0016] Furthermore, the heat insulation portion completely covers the outer wall surface of the rear heat sink.

[0017] The technical solution of the present invention is applied, and the electric heater includes an electric heater body and a heat insulating part, and the heat insulating part is connected to the outer wall surface of the electric heater body, so that the heat insulating part and the outer wall surface of the electric heater body form a sealed heat insulating cavity. By providing the heat insulating part, the outer wall surface of the electric heater body can be prevented from directly contacting the human body, thereby preventing the human body from being scalded, and playing an anti-scalding role.

[0018] The heat insulating part is provided with a through hole connected to the heat insulating cavity, so that liquid can be injected into the heat insulating cavity through the through hole; thus, the liquid in the heat insulating cavity can directly contact the electric heater body, and the electric heater body can directly heat the liquid in the heat insulating cavity, so that the liquid in the heat insulating cavity is heated and evaporated to form water vapor, and the water vapor can be discharged into the environment where the electric heater is located through the through hole to humidify the environment where the electric heater is located, thereby realizing the humidification function. In addition, the liquid in the heat insulating cavity can also further play an anti-scalding role.

[0019] The present application reduces the number of parts and avoids storage problems by integrating the humidification structure with the electric heater body. The electric heater body is in direct contact with the liquid in the insulation cavity, which can ensure the heating effect of the liquid in the insulation cavity, thereby ensuring the evaporation effect of the liquid and further ensuring the humidification effect.

In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0037] The present invention provides an electric heater, please refer to Figures 2 to 9 The electric heater includes an electric heater body 10 and a heat insulating portion 20, and the heat insulating portion 20 is connected to the outer wall surface of the electric heater body 10, so that the heat insulating portion 20 and the outer wall surface of the electric heater body 10 form a sealed heat insulating cavity 21. By providing the heat insulating portion 20, the outer wall surface of the electric heater body 10 can be prevented from directly contacting the human body, thereby preventing the human body from being scalded, and playing an anti-scalding role.

[0038] In the present application, a through hole 22 is provided on the heat insulating part 20 and communicated with the heat insulating cavity 21, so that liquid can be injected into the heat insulating cavity 21 through the through hole 22; in this way, the liquid in the heat insulating cavity 21 can directly contact the electric heater body 10, and the electric heater body 10 can directly heat the liquid in the heat insulating cavity 21, so that the liquid in the heat insulating cavity 21 is heated and evaporated to form water vapor, and the water vapor can be discharged into the environment where the electric heater is located through the through hole 22 to humidify the environment where the electric heater is located, thereby realizing the humidification function. In addition, the liquid in the heat insulating cavity 21 can also further play an anti-scalding role.

[0039] In the prior art, in order to realize the humidification function, a humidification box component is added separately, which not only results in a large number of parts, but also has a poor humidification effect and is inconvenient to store. The present application reduces the number of parts and avoids the storage problem by integrating the humidification structure with the electric heater body 10. The electric heater body 10 is in direct contact with the liquid in the insulation cavity 21, which can ensure the heating effect of the liquid in the insulation cavity 21, thereby ensuring the evaporation effect of the liquid and further ensuring the humidification effect.

[0040] Specifically, the liquid injected into the heat insulation cavity 21 is water.

[0041] Specifically, at least one through-hole unit 220 is formed on the heat insulation portion 20 , and the through-hole unit 220 includes at least one through-hole 22 .

[0042] like Figure 6 As shown, two through-hole units 220 are provided on the heat insulating portion 20 .

[0043] Specifically, the heat insulating part 20 is provided with a groove 24, and each through-hole unit 220 corresponds to one groove 24. That is, when one through-hole unit 220 is provided on the heat insulating part 20, one groove 24 is provided on the heat insulating part 20; when multiple through-hole units 220 are provided on the heat insulating part 20, multiple grooves 24 are provided on the heat insulating part 20, and multiple through-hole units 220 are provided in one-to-one correspondence with multiple grooves 24.

[0044] The through hole 22 of each through hole unit 220 is formed on a bottom wall of the corresponding groove 24 .

[0045] Specifically, the through hole 22 is opened at the top of the heat insulation part 20 , that is, the through hole unit 220 is opened at the top of the heat insulation part 20 , and the groove 24 is opened at the top of the heat insulation part 20 .

[0046] The groove 24 is provided to facilitate liquid injection and to prevent liquid from flowing out when liquid is injected into the heat insulation cavity 21 through the through hole 22 .

[0047] Optionally, the groove 24 is a square groove.

[0048] In the present application, a drain port 23 connected to the insulation cavity 21 is provided on the insulation part 20 so that the liquid in the insulation cavity 21 can be discharged through the drain port 23; a plugging member 231 is provided at the drain port 23, and the plugging member 231 is detachably provided.

[0049] Typically, the blocking member 231 is disposed at the drain port 23 to block the drain port 23. When the liquid in the insulation cavity 21 needs to be discharged, the blocking member 231 disposed at the drain port 23 is removed from the drain port 23 to open the drain port 23, and the liquid in the insulation cavity 21 can be discharged through the drain port 23.

[0050] Optionally, the blocking member 231 is made of rubber; for example, the blocking member 231 is made of silicone.

[0051] Optionally, when cleaning or liquid replacement is required, the blocking member 231 at the liquid drain port 23 may be removed from the liquid drain port 23 to open the liquid drain port 23 and discharge the liquid in the heat insulation cavity 21 through the liquid drain port 23 .

[0052] Specifically, the drain port 23 is opened at the bottom of the heat insulating portion 20 .

[0053] In the present application, optionally, the heat insulation part 20 is a shell structure.

[0054] In the present application, optionally, the electric heater body 10 is an electric oil heater; the heat insulating portion 20 is used to connect with the rear heat sink 11 of the electric oil heater, so that the heat insulating portion 20 and the rear heat sink 11 of the electric oil heater form an insulation cavity 21. The liquid in the insulation cavity 21 can directly contact the rear heat sink 11, and the rear heat sink 11 can directly heat the liquid in the insulation cavity 21.

[0055] By connecting the heat insulating part 20 with the tail fin 11 of the electric oil heater and enclosing a heat insulating cavity 21, the heat insulating part 20 can shield the tail fin 11, preventing the tail fin 11 from being exposed and affecting the aesthetics of the electric heater product, that is, the heat insulating part 20 also has a certain decorative effect. In addition, the heat insulating part 20 of the present application can play a role in preventing scalding, so the tail fin anti-scalding structure of the existing electric oil heater (such as the tail fin heat insulating sheet) can be eliminated, thereby reducing the number and cost of the heater body parts and improving production efficiency.

[0056] Since the temperature of the tail fin 11 is relatively high, the heat insulating portion 20 can be provided to prevent scalding, thereby preventing the high temperature tail fin 11 from scalding the human body. In addition, the liquid in the heat insulating cavity 21 can further prevent the tail fin from scalding.

[0057] Specifically, the tail heat sink 11 includes a first heat sink 111 and a second heat sink 112, which enclose a tail oil guide channel, a tail upper oil bag and a tail lower oil bag; the tail upper oil bag and the tail lower oil bag are respectively located at the upper end and the lower end of the tail oil guide channel.

[0058] Specifically, the second heat sink 112 is located on a side of the first heat sink 111 away from the head heat sink of the oil heater; the heat insulation portion 20 and a side wall of the second heat sink 112 away from the first heat sink 111 form a heat insulation cavity 21.

[0059] Specifically, the first heat sink 111 and the second heat sink 112 are welded.

[0060] Specifically, the heat insulating portion 20 is welded to the rear heat sink 11 ; that is, the heat insulating portion 20 is welded to the first heat sink 111 and / or the second heat sink 112 .

[0061] Specifically, the first heat sink 111 is also called a large heat sink, and the second heat sink 112 is also called a small heat sink.

[0062] Specifically, the heat insulating portion 20 completely blocks the outer wall surface of the rear heat sink 11; the outer wall surface of the rear heat sink 11 refers to the wall surface of the rear heat sink 11 on one side away from the head heat sink of the electric oil heater; in this way, a better scalding prevention effect can be achieved.

[0063] Optionally, the heat insulation portion 20 has a similar appearance to the tail heat sink 11 .

[0064] In the present application, a edging structure 25 is provided at the connection between the insulation part 20 and the electric heater body 10, so that the edging structure 25 wraps and seals the connection between the insulation part 20 and the electric heater body 10; in this way, the sealing of the insulation cavity 21 can be ensured, and the welding of the insulation part 20 and the electric heater body 10 is also facilitated.

[0065] Optionally, the edging structure 25 and the heat insulation part 20 are an integral structure.

[0066] Specifically, the edge wrapping structure 25 wraps the connection between the heat insulation part 20 and the tail heat sink 11 .

[0067] Specifically, the edge wrapping structure 25 wraps around the outer peripheral edge of the tail heat sink 11. Further, the edge wrapping structure 25 wraps around the outer peripheral edge of the first heat sink 111 and the outer peripheral edge of the second heat sink 112.

[0068] Specifically, the edge structure 25 and the top wall of the heat insulation portion 20 form a sink structure 26 .

[0069] During specific assembly, the first heat sink 111 and the second heat sink 112 are first combined, and then the insulation part 20 is wrapped around the first heat sink 111. The pre-installed first heat sink 111 and the second heat sink 112 are wrapped together through the edging structure 25 on the insulation part 20, and they are pressed and welded together through seam welding equipment to achieve sealing and fixation on all sides; an insulation cavity 21 is formed between the insulation part 20 and the tail heat sink 11.

[0070] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0071] In the electric heater provided by the present invention, the electric heater includes an electric heater body 10 and a heat insulating portion 20, and the heat insulating portion 20 is connected to the outer wall surface of the electric heater body 10, so that the heat insulating portion 20 and the outer wall surface of the electric heater body 10 form a sealed heat insulating cavity 21. By providing the heat insulating portion 20, the outer wall surface of the electric heater body 10 can be prevented from directly contacting the human body, thereby preventing the human body from being scalded, and playing an anti-scalding role.

[0072] The heat insulating part 20 is provided with a through hole 22 connected to the heat insulating cavity 21, so that liquid can be injected into the heat insulating cavity 21 through the through hole 22; in this way, the liquid in the heat insulating cavity 21 can directly contact the electric heater body 10, and the electric heater body 10 can directly heat the liquid in the heat insulating cavity 21, so that the liquid in the heat insulating cavity 21 is heated and evaporated to form water vapor, and the water vapor can be discharged into the environment where the electric heater is located through the through hole 22 to humidify the environment where the electric heater is located, thereby realizing the humidification function. In addition, the liquid in the heat insulating cavity 21 can also further play an anti-scalding role.

[0073] The present application reduces the number of parts and avoids storage problems by integrating the humidification structure with the electric heater body 10. The electric heater body 10 is in direct contact with the liquid in the insulation cavity 21, which can ensure the heating effect of the liquid in the insulation cavity 21, thereby ensuring the evaporation effect of the liquid and further ensuring the humidification effect.
