Description

Technical Field

[0001] This utility model relates to the field of electric furnace technology, and in particular to an electric furnace wire fixing structure and an electric furnace. Background Technology

[0002] An electric oven, also known as an electric stove, is a cooking device that uses electricity as a heat source. It is widely used in homes, restaurants, outdoor barbecues, and other settings. It converts electrical energy into heat energy through heating wires (i.e., resistance wires) to heat food. The heating wires are the core heating element of the electric oven and are mostly made of nickel-chromium alloy or iron-chromium-aluminum alloy.

[0003] In existing technology, the fixing structure of the heating element is generally a metal sheet, which fixes and supports one end of the heating element to the interior of the high-temperature ceramic cavity in the electric furnace. The heating element is generally in the shape of a spiral vortex. When the heating element is at a high temperature for a long time, it will deform downward under the influence of its own gravity, especially the heating element far away from the edge of the metal sheet support. As the heating element gradually deforms downward, it will gradually move away from the baking pan, which will lead to problems such as poor heating efficiency of the electric furnace and uneven heating of the electric baking pan. Utility Model Content

[0004] This utility model addresses the problem that heating wires deform downwards under their own weight, especially those far from the edge of the metal sheet support. As the heating wires deform downwards, they gradually move away from the baking pan, leading to decreased heating efficiency and uneven heating of the baking pan. This invention provides a heating wire fixing structure and an electric oven.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an electric heating wire fixing structure, comprising a fixing block, characterized in that: the fixing block is installed on the outer surface of the electric heating wire body, the fixing block is disposed inside the ceramic cavity, and an auxiliary device is provided on the outer surface of the fixing block, the auxiliary device supporting the bottom of the electric heating wire body through three auxiliary blocks.

[0006] The effect achieved by the above components is as follows: by setting three auxiliary blocks to support and limit the heating element body, it helps to prevent the heating element body, which is far from the support of the fixed blocks, from gradually moving away from the baking pan. At the same time, the three auxiliary blocks are evenly distributed at the bottom of the heating element body, and can also adjust different positions of the heating element body separately. This makes the distance between different positions of the heating element body and the electric baking pan as equal as possible, thereby improving the heating efficiency of the electric oven to a certain extent and mitigating problems such as uneven heating of the electric baking pan.

[0007] Preferably, the auxiliary device includes a ring welded to both sides of the extension plate and inserted into the inner wall of the ceramic cavity. Three extension blocks are uniformly fixedly installed on the inner side of the ring. A threaded rod is rotatably installed on the inner wall of the extension block through a bearing. An auxiliary block is threadedly connected to the outer surface of the threaded rod. The three auxiliary blocks are uniformly fixedly installed on the outer surface of the heating element body.

[0008] The effect achieved by the above components is as follows: when the threaded rod is rotated, the threaded rod will drive the auxiliary block to move vertically. Then, when the heating element body deforms downward, the threaded rod can adjust the auxiliary block, so that the auxiliary block drives the heating element body to deform upward. At the same time, when the threaded rod stops rotating, the threaded rod can also fix the auxiliary block. The auxiliary block can support and limit the heating element body, which helps to prevent the heating element body from gradually moving away from the baking pan.

[0009] Preferably, the auxiliary block is made of high-temperature resistant ceramic material.

[0010] The effect achieved by the above components is that the ceramic material is non-conductive, thus preventing the current flowing through the heating element body from being diverted, thereby ensuring the normal heating of the heating element body. At the same time, the high-temperature resistant ceramic material can maintain good physical properties in high-temperature environments, thus enabling the auxiliary block to support the heating element body for a long time.

[0011] Preferably, the lengths of the three extension blocks and the three auxiliary blocks are all different.

[0012] The effect achieved by the above components is as follows: the heating element body is in the shape of a spiral vortex, the distance between the heating element body and the inner side of the ring is different at different positions, and the auxiliary blocks and extension blocks of different lengths are to ensure that the heating element at different positions can be supported.

[0013] Preferably, each of the threaded rods has a regular hexagonal groove at its top end, and an operating block is inserted into the top end of one of the threaded rods.

[0014] The effects achieved by the above components are as follows: rotating the operating block can drive the connected threaded rod to rotate; the protrusions on the outer surface of the operating block can effectively increase the friction of the outer surface of the operating block, making it easier to rotate the threaded rod; at the same time, the operating block is detachable, so multiple threaded rods can be adjusted through one operating block; and the operating block does not need to be placed in a high-temperature environment for a long time after disassembly, making it easier to use.

[0015] Preferably, the inner side of the ring is provided with a disassembly and assembly assembly, which includes two circular hole blocks. The two circular hole blocks are symmetrically installed on the inner wall of the ring. A threaded pin is inserted into the inner wall of the circular hole block. One end of the threaded pin is fixedly installed at the bottom of the inner wall of the ceramic cavity. A nut is threadedly connected to the outer surface of the threaded pin.

[0016] The effect achieved by the above components is as follows: when the threaded pin is inserted into the inner wall of the round hole block and the nut is rotated, the nut presses against the round hole block, causing the round hole block to abut against the bottom of the ceramic cavity. This fixes the ring and the inner wall of the ceramic cavity, while also allowing the connection between the ring and the ceramic cavity to be released, making it easier to lift the heating element body for cleaning the inside of the ceramic cavity.

[0017] Preferably, a U-shaped block is fitted onto the outer surface of the circular hole block, and the U-shaped block is installed at the bottom of the inner wall of the ceramic cavity.

[0018] The effect achieved by the above components is that by setting up the U-shaped block, the U-shaped block can quickly position the circular hole block, and at the same time, the fixing of the circular ring is more stable.

[0019] Preferably, the electric furnace includes a furnace body, a baking tray, a sludge collection tank, a ceramic cavity, an electric heating wire body, and a fixing block. The electric heating wire fixing structure is disposed inside the ceramic cavity. The baking tray is disposed on the top of the furnace body. The sludge collection tank is installed on the inner wall of the furnace body. The ceramic cavity is disposed at the bottom of the inner wall of the furnace body. The sludge collection tank is sleeved on the outer surface of the ceramic cavity. The fixing block is installed at the bottom of the inner wall of the ceramic cavity. The two ends of the electric heating wire pass through the inner walls of the furnace body, the ceramic cavity, and the fixing block, and are arranged in a spiral shape inside the ceramic cavity.

[0020] The effect achieved by the above components is as follows: after the power is turned on and the control switch on the oven body is activated, the current will flow to the heating element body. The heating element body is essentially a resistor. After the power is turned on, it will release heat, which will then heat the baking tray on top. The baking tray has through holes, and the impurities produced by baking food will flow into the sludge collection tank through the through holes for easy centralized treatment.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by setting three auxiliary blocks to support and limit the heating element body, it is beneficial to prevent the heating element body, which is far from the support of the fixed blocks, from gradually moving away from the baking pan. At the same time, the three auxiliary blocks are evenly distributed at the bottom of the heating element body, and can also adjust different positions of the heating element body separately. This ensures that the distance between different positions of the heating element body and the electric baking pan is as equal as possible, thereby improving the heating efficiency of the electric oven to a certain extent and mitigating problems such as uneven heating of the electric baking pan.

[0024] Example 1, referring to Figures 2-5 As shown, this embodiment discloses a heating element fixing structure, including a fixing block 3. The fixing block 3 is installed on the outer surface of the heating element body 2 and is disposed inside the ceramic cavity 1. An auxiliary device 4 is provided on the outer surface of the fixing block 3. The auxiliary device 4 supports the bottom of the heating element body 2 through three auxiliary blocks 44. By setting three auxiliary blocks 44 to support and limit the heating element body 2, it is beneficial to prevent the heating element body 2, which is far away from the support of the fixing block 3, from gradually moving away from the baking pan 7. At the same time, the three auxiliary blocks 44 are evenly distributed on the bottom of the heating element body 2, and can also adjust different positions of the heating element body 2 separately. This allows the distance between different positions of the heating element body 2 and the electric baking pan 7 to be as equal as possible, thereby improving the heating efficiency of the electric oven to a certain extent and alleviating the problem of uneven heating of the electric baking pan 7.

[0025] Reference Figures 2-5As shown, the auxiliary device 4 includes a ring 41, which is welded to both sides of the extension plate and inserted into the inner wall of the ceramic cavity 1. Three extension blocks 42 are evenly fixedly installed on the inner side of the ring 41. A threaded rod 43 is rotatably installed on the inner wall of the extension block 42 via a bearing. An auxiliary block 44 is threadedly connected to the outer surface of the threaded rod 43. The three auxiliary blocks 44 are evenly fixedly installed on the outer surface of the heating element body 2. Rotating the threaded rod 43 will cause the auxiliary blocks 44 to move vertically. Thus, when the heating element body 2 deforms downward, the auxiliary blocks 44 can be adjusted by the threaded rod 43, so that the auxiliary blocks... When the heating element body 2 is deformed upwards by the rotation of the threaded rod 43, the threaded rod 43 can also fix the auxiliary block 44. The auxiliary block 44 can support and limit the heating element body 2, which helps to prevent the heating element body 2 from gradually moving away from the baking pan 7. The auxiliary block 44 is made of high-temperature resistant ceramic material. Ceramic material is non-conductive, so it will not divert the current flowing through the heating element body 2, thus ensuring the normal heating of the heating element body 2. At the same time, the high-temperature resistant ceramic material can maintain good physical properties in high-temperature environment, so that the auxiliary block 44 can support the heating element body 2 for a long time.

[0026] Reference Figures 2-5 As shown, the lengths of the three extension blocks 42 and the three auxiliary blocks 44 are not equal. The heating element body 2 is in the shape of a spiral vortex. The distance between the heating element body 2 and the inner side of the ring 41 is different at different positions. The auxiliary blocks 44 and extension blocks 42 of different lengths are to ensure that the heating element at different positions can be supported. The top of each threaded rod 43 is provided with a regular hexagonal groove. An operating block 45 is inserted into the top of one of the threaded rods 43. Rotating the operating block 45 can drive the threaded rod 43 connected to it to rotate. The protrusion on the outer surface of the operating block 45 can effectively increase the friction of the outer surface of the operating block 45, making it easier to rotate the threaded rod 43. At the same time, the operating block 45 is detachable, so multiple threaded rods 43 can be adjusted through one operating block 45. Moreover, the operating block 45 does not need to be placed in a high-temperature environment for a long time after disassembly, making it easier to use.

[0027] Reference Figures 2-5As shown, a disassembly assembly 5 is provided on the inner side of the ring 41. The disassembly assembly 5 includes two circular hole blocks 51, which are symmetrically installed on the inner wall of the ring 41. Threaded pins 52 are inserted into the inner wall of the circular hole blocks 51. One end of the threaded pin 52 is fixedly installed at the bottom of the inner wall of the ceramic cavity 1. A nut 53 is threaded onto the outer surface of the threaded pin 52. The threaded pin 52 is inserted into the inner wall of the circular hole block 51, and the nut 53 is rotated, causing the nut 53 to press against the circular hole block 51, allowing the circular hole block 51 to contact the ceramic cavity 1. The bottom of the ring 41 is abutted, which can fix the inner wall of the ceramic cavity 1 and make the connection between the ring 41 and the ceramic cavity 1 detachable, so as to make it easier to lift the heating wire body 2 for cleaning the inside of the ceramic cavity 1; the outer surface of the round hole block 51 is fitted with a U-shaped block 54, which is installed at the bottom of the inner wall of the ceramic cavity 1. By setting the U-shaped block 54, the round hole block 51 can be quickly positioned, and the fixing of the ring 41 is more stable.

[0028] Reference Figures 1-3 As shown, the electric stove includes a stove body 6, a baking tray 7, a sludge collection tank 8, a ceramic cavity 1, an electric heating wire body 2, and a fixing block 3. The electric heating wire fixing structure is set inside the ceramic cavity 1. The baking tray 7 is set on the top of the stove body 6. The sludge collection tank 8 is installed on the inner wall of the stove body 6. The ceramic cavity 1 is set at the bottom of the inner wall of the stove body 6. The sludge collection tank 8 is fitted on the outer surface of the ceramic cavity 1. The fixing block 3 is installed at the bottom of the inner wall of the ceramic cavity 1. The two ends of the electric heating wire pass through the inner walls of the stove body 6, the ceramic cavity 1, and the fixing block 3, and are set in a spiral shape inside the ceramic cavity 1. After the power is turned on and the control switch on the stove body 6 is turned on, the current will flow to the electric heating wire body 2. The electric heating wire body 2 is essentially a resistor. After the power is turned on, it will release heat, which will heat the baking tray 7 on the top. The baking tray 7 has through holes. Impurities produced by baking food will flow into the sludge collection tank 8 through the through holes for centralized treatment.

[0029] Working principle: Insert the operating block 45 into the top of the threaded rod 43, and rotate the threaded rod 43 through the operating block 45. The threaded rod 43 will drive the auxiliary block 44 to move vertically. When the heating element body 2 deforms downward, the auxiliary block 44 can be adjusted through the threaded rod 43, so that the auxiliary block 44 drives the heating element body 2 to deform upward. At the same time, when the rotation of the threaded rod 43 stops, the threaded rod 43 can also fix the auxiliary block 44. The auxiliary block 44 can support and limit the heating element body 2, which helps to prevent the heating element body 2 from gradually moving away from the baking pan 7. At the same time, the three auxiliary blocks 44 are evenly distributed at the bottom of the heating element body 2, and can also adjust different positions of the heating element body 2 separately, so that different positions of the heating element body 2 are in contact with the baking pan 7. The distances between them should be as equal as possible; the auxiliary block 44 is made of high-temperature resistant ceramic material. Ceramic material is non-conductive, so it will not divert the current flowing through the heating element body 2, thus ensuring the normal heating of the heating element body 2. At the same time, the high-temperature resistant ceramic material can maintain good physical properties in high-temperature environments, so that the auxiliary block 44 can support the heating element body 2 for a long time; insert the threaded pin 52 into the inner wall of the round hole block 51, insert the round hole block 51 into the inner wall of the U-shaped block 54, and rotate the nut 53 so that the nut 53 presses the round hole block 51, so that the round hole block 51 abuts against the bottom of the ceramic cavity 1, which can fix the ring 41 and the inner wall of the ceramic cavity 1, and at the same time, the connection between the ring 41 and the ceramic cavity 1 can be released, so that it is easier to lift the heating element body 2 to facilitate cleaning the inside of the ceramic cavity 1.
