Description

Technical Field

[0001] This utility model relates to the field of electric heating tube technology, specifically a dual-group electric heating tube that can be used both vertically and horizontally. Background Technology

[0002] The dual-purpose (vertical and horizontal) dual-group electric heating element is a heating device that can be installed vertically or horizontally. It is typically used for heating media. This type of heating element is characterized by its adaptability to different installation spaces and needs, and provides more flexible temperature control and higher safety through two independently operating heating units. Existing electric heating elements are only fixed at one end during installation, and the other end may bend or deform under gravity, especially in horizontal installations. Even in vertical installations, fluid flow or external factors can cause vibration of the heating element. Furthermore, when existing electric heating elements are installed on water tanks, the water inlet position is fixed. If the water inlet is at the bottom and a side-mounted installation is required, the water inlet will enter from the side. Water entering from the side will impact the heating element, causing glass formation inside the water tank, which in turn causes mechanical vibration of the heating element. Long-term vibration will cause fatigue damage to the heating element and its connectors, shortening its service life. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a dual-purpose electric heating tube that can be used for both vertical and horizontal installations. The supporting component can support the other end of the heating tube to support and distribute the weight of the heating tube, preventing displacement or vibration during operation, and preventing deformation or damage to one end due to lack of support when installed horizontally. Secondly, the water inlet component can change the water inlet position according to the installation posture, so that water enters from the bottom whether installed vertically or horizontally, avoiding water flow impact and waves that could cause mechanical vibration of the heating tube. This also ensures that the heating tube is fully submerged, improving heating efficiency and reducing the risk of dry burning.

[0004] The technical problem to be solved by this utility model is achieved by the following technical solution:

[0005] A dual-purpose (vertical and horizontal) electric heating element includes: a mounting base, a junction box at the bottom of the mounting base, and two sets of electric heating elements at the top of the mounting base. The two sets of electric heating elements are arranged in a cross pattern, and each set consists of three electric heating elements.

[0006] A support assembly is disposed outside the two sets of heating tubes and is used to support the two sets of heating tubes. The support assembly includes: a support ring, a fixing rod, a storage cavity, a screw, and a support block.

[0007] A water receiving assembly is located outside the junction box and is used to control the water inlet direction. The water receiving assembly includes: a mounting groove, a water receiving box, a side water inlet, a top water inlet, and a water inlet.

[0008] Furthermore, the two sets of heating elements are provided with a support ring on the outside, and four fixing rods are fixedly connected to the periphery of the support ring. The four fixing rods are arranged in a ring array. Each of the four fixing rods has a storage cavity at one end, and each storage cavity is provided with a screw. The end of the screw away from the fixing rod is fixedly connected to a support block.

[0009] Furthermore, the junction box has an installation groove on its periphery, a water receiving box is provided inside the installation groove, a side water inlet is provided on one side of the water receiving box, an upper water inlet is provided on the top of the water receiving box, and a water receiving port is provided at the bottom of the water receiving box.

[0010] Furthermore, a through hole is provided at the center of the support ring, and mounting holes for use with the two sets of heating tubes are provided on the support ring. A ceramic guide ring is fixedly installed inside the mounting hole, and the ceramic guide ring is located outside the heating tube.

[0011] Furthermore, each of the four fixed rods has a movable cavity, and a threaded sleeve is provided inside the movable cavity. Several anti-slip grooves are provided on the periphery of the threaded sleeve, and the threaded sleeve is threaded to the outside of the screw rod.

[0012] Furthermore, the screw has two symmetrically arranged guide grooves on its outer side, and two symmetrically arranged guide blocks are fixedly connected to the inner wall of the storage cavity. The two storage cavities are located inside the two guide grooves.

[0013] Furthermore, the side inlet is equipped with valve a, the upper inlet is equipped with valve b, one end of the side inlet is fixedly connected to connecting pipe a, the top end of the upper inlet is fixedly connected to connecting pipe b, and the top end of connecting pipe b passes through the mounting base and extends to the outside.

[0014] The beneficial effects of this utility model are:

[0015] The advantage of this utility model is that the other end of the heating tube can be supported by the support component to support and distribute the weight of the heating tube, preventing it from shifting or vibrating during operation, and preventing deformation or damage of one end of the horizontally installed type due to lack of support.

[0016] Secondly, the water inlet component can change the water inlet position according to the installation posture, so that water enters from the bottom whether it is installed vertically or horizontally, avoiding water flow impact and waves that could cause mechanical vibration of the heating element. This also ensures that the heating element is fully submerged, improving heating efficiency and reducing the risk of dry burning. Attached Figure Description

[0024] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments. Example 1

[0026] like Figures 1-6 As shown, a dual-purpose (vertical and horizontal) double-group electric heating element includes: a mounting base 1, a junction box 11 at the bottom of the mounting base 1, and two groups of electric heating elements 12 at the top of the mounting base 1, the two groups of electric heating elements 12 being arranged in a cross pattern, each group consisting of three electric heating elements 12; a support assembly, located outside the two groups of electric heating elements 12, for supporting the two groups of electric heating elements 12; and a water inlet assembly, located outside the junction box 11, for controlling the direction of water inlet.

[0027] During installation and use, choose the appropriate vertical or horizontal installation position according to your needs. The two sets of electric heating elements 12 are two independent heating parts, each of which can be controlled independently. This allows users to adjust the heating power according to actual needs and improve the energy efficiency ratio. Because it is a dual-set design, if one set fails, the other set can continue to work, thus ensuring basic heating needs. Typically, the electric heating element 12 is installed in the center of the water heater tank, and the tank is mostly cylindrical. The other end of the electric heating element 12 can be supported by the support component to support and distribute the weight of the electric heating element 12, preventing displacement or vibration during operation, and preventing deformation or damage to one end due to lack of support in horizontal installation. Secondly, select the matching water inlet method according to the installation position through the water inlet component. In vertical or horizontal installation, water enters from the bottom and flows out from the top, which ensures that the electric heating element is fully submerged, improves heating efficiency, and reduces the risk of dry burning. Example 2

[0028] Based on Embodiment 1, the support assembly includes: a support ring 2, fixing rods 21, a receiving cavity 22, a screw 23, and a support block 24. The two sets of heating elements 12 are externally provided with a support ring 2. Four fixing rods 21 are fixedly connected to the periphery of the support ring 2, arranged in a circular array. Each of the four fixing rods 21 has a receiving cavity 22 at one end, and each receiving cavity 22 is provided with a screw 23. The end of the screw 23 furthest from the fixing rod 21 is fixedly connected to a support block 24. A through hole 25 is provided at the center of the support ring 2, and a fitting for the two sets of heating elements 12 is provided on the support ring 2. The mounting hole 26 is used for the set. A ceramic guide ring 27 is fixedly installed inside the mounting hole 26. The ceramic guide ring 27 is located outside the heating tube 12. Each of the four fixed rods 21 has a movable cavity 28. A screw sleeve 29 is provided inside the movable cavity 28. Several anti-slip grooves 210 are provided on the periphery of the screw sleeve 29. The screw sleeve 29 is threaded to the outside of the screw rod 23. Two symmetrically arranged guide grooves 211 are provided on the outside of the screw rod 23. Two symmetrically arranged guide blocks 212 are fixedly connected to the inner wall of the storage cavity 22. The two storage cavities 22 are located inside the two guide grooves 211.

[0029] After the heating element 12 is installed, adjust the position of the support ring 2. The support ring 2 can slide outside the two sets of heating elements 12. The ceramic guide ring 27 has high temperature resistance and can directly contact the heating element 12 without damaging it and ensure its durability. Move the support ring 2 to the other end of the heating element 12. Then, rotate the screw sleeve 29 in a diagonal sequence. The anti-slip groove 210 facilitates the rotation of the screw sleeve 29. The screw sleeve 29 rotates and engages with the screw rod 23. Because the screw rod 23 is restricted by the guide groove 211 and the guide block 212, the screw rod 23 can only move along the horizontal direction of the guide block 212. The movement of the screws causes the screw 23 to move out of the receiving cavity 22 when the threads are engaged, so that the support block 24 fits against the inner wall of the water tank. The length of the two diagonally opposite screws 23 is controlled to ensure that the length of the four screws 23 is consistent, so that the heating element 12 is kept in the center position. When the heating element 12 needs to be removed for subsequent cleaning of the water tank, it is difficult to turn the screw sleeve 29 manually due to the presence of scale. Pliers are needed to clamp the screw sleeve 29 and turn it. Since the screw sleeve 29 and the support ring 2 are designed at a 90° angle, and the support ring 2 is facing the side of the installation port, the pliers can clamp the screw sleeve 29, which is convenient for turning the screw sleeve 29 and facilitating disassembly. Example 3

[0030] Based on Embodiment 1, the water receiving assembly includes: a mounting groove 3, a water receiving box 31, a side water inlet 32, an upper water inlet 33, and a water receiving port 34. The mounting groove 3 is provided on the periphery of the junction box 11, and the water receiving box 31 is provided inside the mounting groove 3. The side water inlet 32 ​​is provided on one side of the water receiving box 31, the upper water inlet 33 is provided on the top of the water receiving box 31, and the water receiving port 34 is provided on the bottom of the water receiving box 31. A valve a35 is provided on the side water inlet 32, and a valve b36 is provided on the upper water inlet 33. A connecting pipe a37 is fixedly connected to one end of the side water inlet 32, and a connecting pipe b38 is fixedly connected to the top end of the upper water inlet 33. The top end of the connecting pipe b38 passes through the mounting base 1 and extends to the outside.

[0031] After the heating element 12 is installed, connect the external water source to the water inlet 34. Select the water inlet method according to the installation posture of the heating element 12. For vertical installation, open valve b36. When the water source is opened, the water enters the water collection box 31, then enters the connecting pipe b38 from the upper water inlet 33, and then flows into the water tank. This is how water enters from the bottom. For horizontal installation, connect the connecting pipe a37 to the water inlet reserved at the bottom of the water tank, then open valve a35. The water flows from the water collection box 31 to the side water inlet 32, and then enters the water tank along the connecting pipe a37. The water enters from the bottom, which can ensure that the heating element is fully submerged, improve heating efficiency and reduce the risk of dry burning.
