Description

Technical Field

[0001] This utility model relates to the field of cooking equipment technology, specifically a heat dissipation structure for cooking equipment. Background Technology

[0002] Chinese utility model patent CN202421378674.0 discloses an ultra-thin induction cooker. Its electrical cavity is equipped with an air guide plate, and a cooling fan directs cool air to the coil and circuit board via the air guide plate. When the induction cooker is working, the circuit board and cooling fan within the electrical cavity, along with the air guide plate directing the cool air to the coil and circuit board, effectively improve the heat dissipation of key components and significantly enhance the system's stability and reliability. However, the bottom shell only has an air guide plate at the mounting position of the cooling fan. This means that after the cooling fan is installed, its top and sides are open, causing cool air to scatter erratically through these open areas. This not only affects the heat dissipation effect, preventing the coil and circuit board from receiving timely and effective cooling, but also generates wind noise, impacting the user experience. Therefore, further improvement is necessary. Utility Model Content

[0003] The present invention aims to provide a heat dissipation structure for cooking equipment to overcome the shortcomings of the prior art.

[0004] A heat dissipation structure for a cooking device designed for this purpose includes a bottom shell, a heating plate, a circuit board, an outer shell, and a fan box. The heating plate and the circuit board are respectively fixed on the bottom shell. The outer shell surrounds the heating plate and the circuit board and is fixed on the bottom shell. A cooling fan is provided inside the fan box. An air outlet is provided on the side of the fan box facing the circuit board. A guide plate is provided on the fan box, or the bottom shell, or the outer shell corresponding to the air outlet to guide air towards the heating plate. The side of the top air plate of the fan box extends towards the air outlet.

[0005] The length of the side extension of the top wind plate exceeds the air outlet, and the length of the side extension of the top wind plate is less than, equal to, or greater than the position where the air guide plate is set.

[0006] The top air plate is disposed on the air box, or the bottom shell, or the outer shell, and is located on the top of the air box and above the air guide plate.

[0007] The top of the air box is provided with a top opening, the cooling fan is fixed inside the air box through the top opening, and the top air plate covers the cooling fan and is fixed on the top opening.

[0008] The cooling fan is fixed inside the air box in a longitudinal, lateral, or inclined manner.

[0009] The air guide plate is arranged in an arc shape or in an inclined linear arrangement, and it is mutually dependent or spaced out from the air outlet and / or the top air plate.

[0010] The air box is separately disposed and fixedly fitted to the bottom shell or the outer shell, or the air box is integrally disposed on the bottom shell or the outer shell.

[0011] The air box is integrally disposed on the rear side of the bottom shell. The air box is located behind the heating plate and on one side of the circuit board. The bottom shell is provided with an air inlet corresponding to the air box.

[0012] The bottom shell or the outer shell is also provided with heat dissipation holes.

[0013] A crystal plate is fixedly mounted on the outer shell, and an electrical cavity is formed between the crystal plate, the outer shell, and the bottom shell. The heating plate, the circuit board, and the fan box are located inside the electrical cavity.

[0014] Because the cooling fan of this invention is located inside the air box, the cooling air can only be blown out from the air outlet, thus avoiding the problems of low air volume and speed, and high wind noise caused by the cooling air blowing around randomly. In addition, the side of the top air plate extends to the air outlet, which can press down the cooling air blown out of the air outlet. At the same time, since the air outlet faces the circuit board and the air guide plate corresponding to the air outlet faces the heating plate, the blowing direction of the cooling air can be effectively limited, so that the cooling air blown out of the air outlet can directly act on the circuit board and be guided to the heating plate through the air guide plate, thereby ensuring effective heat dissipation inside the cooking equipment, making it highly practical.

[0023] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] See Figures 1-8 The heat dissipation structure of this cooking equipment includes a bottom shell 1, a heating plate, a circuit board 2, an outer shell 3, and a fan box 4. The heating plate and the circuit board 2 are fixed on the bottom shell 1, and the outer shell 3 surrounds the heating plate and the circuit board 2 and is fixed on the bottom shell 1. A cooling fan 5 is installed inside the fan box 4. An air outlet 6 is provided on the side of the fan box 4 facing the circuit board 2. A guide plate 7 is provided on the fan box 4, or the bottom shell 1, or the outer shell 3 corresponding to the air outlet 6 to guide the air towards the heating plate. The top air plate 8 of the fan box 4 extends on the side towards the air outlet 6.

[0026] In this embodiment, since the cooling fan 5 is located inside the air box 4, the cooling air can only be blown out from the air outlet 6. This avoids the problems of low air volume and speed, and high wind noise caused by the cooling air blowing around randomly. In addition, the side of the top air plate 8 extends to the air outlet 6, which can press down the cooling air blown out of the air outlet 6. At the same time, since the air outlet 6 faces the circuit board 2 and the air guide plate 7 corresponding to the air outlet 6 faces the heating plate, the blowing direction of the cooling air can be effectively limited. This allows the cooling air blown out of the air outlet 6 to directly act on the circuit board 2 and be guided to the heating plate by the air guide plate 7, thereby ensuring that the inside of the cooking equipment can achieve effective heat dissipation and has strong practicality.

[0027] The direction of airflow for cooling is as follows: Figure 5 , Figure 6 As indicated by the arrow.

[0028] The length of the side extension of the top wind plate 8 exceeds the air outlet 6, and the length of the side extension of the top wind plate 8 is less than, equal to, or greater than the position where the air guide plate 7 is set.

[0029] The top air plate 8 is installed on the air box 4, or the bottom shell 1, or the outer shell 3, and is located on the top of the air box 4 and above the air guide plate 7.

[0030] The top of the air box 4 is provided with a top opening 9. The cooling fan 5 is fixed inside the air box 4 through the top opening 9. The top air plate 8 covers the cooling fan 5 and is fixed on the top opening 9.

[0031] The cooling fan 5 is fixed inside the air box 4 in a vertical, horizontal, or inclined manner.

[0032] The air guide plate 7 is arranged in an arc shape or in an inclined linear arrangement, and it is mutually dependent or spaced together with the air outlet 6 and / or the top air plate 8.

[0033] The air box 4 is separately installed and fixed together with the bottom shell 1 or the outer shell 3, or the air box 4 is integrally installed on the bottom shell 1 or the outer shell 3.

[0034] The air box 4 is integrally set on the rear side of the bottom shell 1. The air box 4 is located behind the heating plate and on one side of the circuit board 2. The bottom shell 1 is provided with an air inlet 10 corresponding to the air box 4.

[0035] The bottom shell 1 or the outer shell 3 is also provided with heat dissipation holes 11.

[0036] A crystal plate 12 is fixedly installed on the outer shell 3. An electrical cavity is formed between the crystal plate 12, the outer shell 3, and the bottom shell 1. The heating plate, the circuit board 2, and the fan box 4 are located inside the electrical cavity.

[0037] Specifically, in this embodiment, the outer shell 3 is fixedly mounted on the bottom shell 1 by fasteners, and the crystal plate 12 is then fixed to the outer shell 3 by adhesive, so that an electrical cavity is formed between the crystal plate 12, the outer shell 3, and the bottom shell 1. The heating plate and the circuit board 2 are respectively mounted on the bottom shell 1 by fasteners. The air box 4 is integrally formed on the rear side of the bottom shell 1. At the same time, the air box 4 is located behind the heating plate and on one side of the circuit board 2. The top of the air box 4 has an open top opening 9. The cooling fan 5 is vertically fixed inside the air box 4 through the top opening 9. The top air plate 8 is fixed to the top opening 9 by fasteners and completely covers the cooling fan 5. The air outlet 6 is opened on one side of the air box 4 and corresponds to the heating plate. The cooling air from the cooling fan 5 can only be blown out from the air outlet 6 on one side. The bottom shell 1 is provided with several air inlets 10 corresponding to the air box 4. When the cooling fan 5 is working, it draws external cooling air into the air box 4 through the air inlets 10 and blows the cooling air in the air box 4 out through the air outlet 6. The air guide plate 7 is integrally set on the bottom shell 1 and is arranged in an arc shape corresponding to the heating plate. The length of the side extension of the top air plate 8 is less than the position of the air guide plate 7. One side of the air guide plate 7 is mutually dependent with the air outlet 6, and the top is mutually dependent with the top air plate 8, so that the air blown out through the air outlet 6 can be compressed by the top air plate 8 and guided by the air guide plate 7 at the same time. In addition, the bottom shell 1 is provided with several heat dissipation holes 11, and the heat in the electrical cavity can be dissipated through the several heat dissipation holes 11.
