Technical Field

[0001] This utility model relates to the field of fixed bracket technology, and in particular to a fixed bracket for a washing machine electric heater. Background Technology

[0002] Washing machines are generally equipped with electric heating functions. Washing clothes with hot water can enhance the activity of detergent, improve the stain removal ability, and high-temperature washing can effectively kill bacteria and mites, meeting health needs. Some models can dry clothes by heating the air, reducing the drying time. The electric heater is the core component to achieve these functions, and the role of the fixing bracket is to ensure the stable installation of the heater, efficient heat transfer and safety. Therefore, it is necessary to design a fixing bracket for the washing machine electric heater.

[0003] To address this, patent CN210394879U discloses a fixing bracket for a washing machine electric heater, comprising a bracket fixing plate. Each corner of the upper end of the bracket fixing plate has a first screw hole. A fixing seat is located at the upper end of the bracket fixing plate.

A fixing cross buckle is located on the outer ring of the middle part of the fixing plate. A third screw hole is located at the upper end of the fixing cross buckle. Matching first bolts, second bolts, and third bolts are respectively installed in the first, second, and third screw holes. An electric heater head is located at the upper end of the bracket fixing plate, inside the fixing plate and the fixing cross buckle. A heating coil is located on one side of the electric heater head.

[0004] While the aforementioned washing machine electric heater mounting bracket is convenient to install and allows for control of the heat dissipation rate, the heating wire is prone to wobbling at one end if the washing machine is bumped after installation, affecting the stability of the installation. Therefore, it is urgent to optimize the stability of the washing machine electric heater mounting bracket. Utility Model Content

[0005] The purpose of this utility model is to provide a fixing bracket for a washing machine electric heater, in order to solve the defect that, after the existing fixing bracket for a washing machine electric heater has been installed, if the washing machine is hit, one end of the heating wire is easy to shake, which affects the stability of the installation.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a fixing bracket for a washing machine electric heater, including a mounting bracket;

[0007] The mounting bracket has uniformly spaced heat dissipation grooves inside. A mounting plate is fixed to one side of the top of the mounting bracket. A support structure is fixed to the side of the top of the mounting bracket away from the mounting plate. The support structure includes a support frame fixed to the side of the top of the mounting bracket away from the mounting plate. Positioning seats are fixed to both sides of the top of the support frame. The top of each positioning seat is interference-fitted with a limit seat.

[0008] An electric heater head is provided on the side of the mounting plate near the support frame, a heating coil is fixed on the side of the electric heater head near the support structure, and a mounting structure is fixed on the side of the electric heater head near the mounting plate.

[0009] A heat dissipation structure is provided below the mounting bracket.

[0010] Furthermore, the heat dissipation slots are evenly distributed inside the mounting bracket.

[0011] Furthermore, the positioning seats are symmetrically distributed at both ends of the support frame, and the inner diameter of the top of the positioning seat is larger than the outer diameter of the heating coil.

[0012] Furthermore, the heat dissipation structure includes a blower, a connecting shaft, a mounting ring, a positioning block, and a fixing bolt. The blower is located below the mounting bracket. A mounting ring is fixed on the outer wall of the top of the blower. A connecting shaft is rotatably connected to both sides of the top of the mounting ring. The top of the connecting shaft extends through a heat dissipation groove to the top of the mounting bracket and is fixedly connected to a positioning block. Fixing bolts penetrate the two sides of the mounting ring away from the connecting shaft.

[0013] Furthermore, the bottom end of the positioning block and the top end of the mounting bracket abut against each other, and the top ends of the fixing bolts pass through the mounting ring and extend into the interior of the mounting bracket.

[0014] Furthermore, the mounting structure includes a mounting block, a mounting bolt, a mounting groove, a positioning shaft, and a limiting cover. The mounting groove is located in the middle of the interior of the mounting plate. The mounting block is fixed to the middle of the side of the electric heater head near the mounting plate. A mounting bolt passes through the interior of the mounting block. Positioning shafts are provided on both sides of the mounting block. A limiting cover is threaded onto the outer wall of one end of each positioning shaft.

[0015] Furthermore, the mounting block and the mounting plate are connected by a mounting slot, the top end of the mounting bolt extends to the outside of the mounting plate, and the bottom end of the mounting bolt passes through the mounting block and extends into the inside of the mounting plate.

[0016] Furthermore, one end of each positioning shaft is fixedly connected to one side of the mounting plate, and the positioning shaft and the mounting plate are slidably connected.

[0017] The advantages of the washing machine electric heater fixing bracket provided by this utility model are:

[0018] By setting up a support structure, and through the symmetrically designed positioning seat and the interference fit limiting seat, the heating coil is firmly fixed in the reserved groove between the positioning seat and the limiting seat, which limits and supports one end of the heating coil to prevent shaking and swaying caused by the vibration of the washing machine. The limiting seat and the heating coil adopt an interference fit, which can be clamped without tools, simplifying the assembly process. This device has the function of supporting and limiting the heating coil, and improves the stability of the washing machine electric heater fixing bracket during use.

[0019] By incorporating a heat dissipation structure, the airflow from the hairdryer can reach the electric heater head and heating coil, facilitating heat dissipation when the heating coil is not in operation. This accelerates heat dissipation from the heat dissipation groove, preventing overheating and damage to the electric heater. When the heating coil is in operation, the hairdryer can work in conjunction with the heating coil to generate hot air, facilitating the drying of clothes. The rotation of the connecting shaft allows the positioning block to pass through the heat dissipation groove and reach the top of the mounting bracket. The positioning block allows the hairdryer to be initially suspended at the bottom of the mounting bracket. This design achieves the functions of convenient heat dissipation and hot air blowing, improving the convenience and efficiency of the washing machine electric heater mounting bracket during use.

[0020] With its installation structure and engaging design between the mounting block and the mounting groove, the device can be quickly positioned without the need for precise bolt adjustments. The mounting bolt extends from the top into the mounting plate and is secured by a threaded connection between the limit cover and the positioning shaft, ensuring a tight fit and preventing loosening. This design allows for easy and quick installation, improving the convenience of using the washing machine's electric heater mounting bracket. Attached Figure Description

[0029] Please see Figures 1-6 The washing machine electric heater fixing bracket provided by this utility model includes a mounting bracket 1.

[0030] Reference Figure 1 , Figure 2 and Figures 4-6 The mounting frame 1 has heat dissipation grooves 2 evenly distributed inside. The heat dissipation grooves 2 are evenly distributed inside the mounting frame 1. A mounting plate 3 is fixed to one side of the top of the mounting frame 1. A support structure 6 is fixed to the side of the top of the mounting frame 1 away from the mounting plate 3. The support structure 6 includes a support frame 61 fixed to the side of the top of the mounting frame 1 away from the mounting plate 3. Positioning seats 62 are fixed to both sides of the top of the support frame 61. The top of the positioning seats 62 is interference-fitted with a limiting seat 63. The positioning seats 62 are symmetrically distributed at both ends of the support frame 61. The inner diameter of the top of the positioning seat 62 is larger than the outer diameter of the heating coil 5.

[0031] After the electric heater head 4 and heating coil 5 are installed on one side of the mounting plate 3 via the mounting structure 8, the end of the heating coil 5 away from the electric heater head 4 is gently lifted upwards so that one end of the heating coil 5 can be placed inside the semi-circular reserved groove at the top of the positioning seat 62, thus limiting one end of the heating coil 5. Then, the locking rod at the bottom of the limiting seat 63 is inserted into the locking groove inside the positioning seat 62 to achieve an interference fit between the positioning seat 62 and the limiting seat 63, thus physically locking one end of the heating coil 5 and preventing the tail end of the heating coil 5 from shaking or wobbling during use.

[0032] Reference Figures 1-6An electric heater head 4 is provided on the side of the mounting plate 3 near the support frame 61. A heating coil 5 is fixed on the side of the electric heater head 4 near the support structure 6. An mounting structure 8 is fixed on the side of the electric heater head 4 near the mounting plate 3. The mounting structure 8 includes a mounting block 81, a mounting bolt 82, a mounting groove 83, a positioning shaft 84, and a limiting cover 85. The mounting groove 83 is opened in the middle position inside the mounting plate 3. The mounting block 81 is fixed in the middle position on the side of the electric heater head 4 near the mounting plate 3. The mounting bolt 82 passes through the inside of the mounting block 81. Positioning shafts 84 are provided on both sides of the mounting block 81. A limiting cover 85 is threadedly connected to the outer wall of one end of the positioning shaft 84. The mounting block 81 and the mounting plate 3 are engaged and connected through the mounting groove 83. The top end of the mounting bolt 82 extends to the outside of the mounting plate 3, and the bottom end of the mounting bolt 82 passes through the mounting block 81 and extends into the inside of the mounting plate 3. One end of the positioning shaft 84 is fixedly connected to one side of the mounting plate 3, and the positioning shaft 84 and the mounting plate 3 are slidably connected.

[0033] During installation, both the mounting block 81 and the positioning shaft 84 are inserted into the interior of the mounting plate 3 and engage with it for quick positioning. Then, the mounting bolt 82 is inserted downwards from the top of the mounting plate 3 until its bottom end passes through the mounting block 81 and extends into the interior of the mounting plate 3. The electric heater head 4 and the heating coil 5 can then be mounted on one side of the mounting plate 3 via the mounting block 81. The limiting cover 85 and one end of the positioning shaft 84 are threaded together to fix and restrict the positioning shaft 84, thereby improving the stability of the electric heater head 4 during installation.

[0034] Reference Figures 1-6 A heat dissipation structure 7 is provided below the mounting bracket 1.

The top ends of the fixing bolts 75 pass through the mounting ring 73 and extend into the interior of the mounting bracket 1.

[0035] When the external power supply is connected and the hair dryer 71 is turned on, the hair dryer 71 will blow air onto the heating coil 5. When the heating coil 5 stops running, the hair dryer 71 can send air to the bottom of the heating coil 5 through the heat dissipation slot 2 to dissipate heat from the heating coil 5. When the heating coil 5 is heating, it can exchange heat with the air blown out by the hair dryer 71 to form hot air, which can be used to dry clothes.
