[0017] The utility model is further described in detail below with reference to the accompanying drawings. A toaster with multi-layer heat insulation function comprises a shell 1, the shell 1 is hollow to form a baking cavity, a baking mechanism is embedded in the baking cavity, and is characterized in that: a heat dissipation zone is formed by leaving a space between the shell 1 and the baking mechanism;

[0018] The shell 1 is covered with an insulating sleeve 4 on the outside, and an installation cavity 41 is hollowed out inside the insulating sleeve 4, and the shell 1 is covered and installed on the installation cavity 41; the bottom of the installation cavity 41 is recessed to form a ventilation groove 42, and the ventilation groove 42 is connected to the installation cavity 41; the front and rear ends of the insulating sleeve 4 are open, and the control device 5 embedded in the front end of the shell 1 is built into the open part; the top of the insulating sleeve 4 is penetrated by an air avoidance groove 44, and the air avoidance groove 44 is connected to the baking cavity; a plurality of heat dissipation holes 43 are arranged on the left and right side walls of the insulating sleeve 4.

[0019] Both sides of the ventilation slot 42 extend upward and penetrate through the side wall of the heat insulation sleeve 4 , and the top of the ventilation slot 42 is higher than the bottom end surface of the heat insulation sleeve 4 .

[0020] The heat dissipation holes 43 are arranged all over the side wall of the heat insulation sleeve 4 , and the heat dissipation holes 43 are connected to the installation cavity 41 .

[0021] The heat insulation sleeve 4 is integrally made of plastic material.

[0022] The heat insulation sleeve 4 is integrally formed by a heat insulation cotton board.

[0023] The baking mechanism comprises a plurality of vertically mounted electric heating plates 2 , and the food to be baked is clamped between adjacent electric heating plates 2 .

[0024] The opposite sides of the adjacent electric heating plates 2 are covered with a protective grid 3 .

[0025] Working principle: In this case, a heat dissipation zone is formed by leaving a space between the shell and the baking mechanism. The heat generated by the baking mechanism is first radiated and transferred to the heat dissipation zone for heat dissipation, which reduces the heat directly transferred to the shell and reduces the temperature of the shell to a certain extent. At this time, the heat dissipation zone forms the first heat dissipation operation. Secondly, the shell body also has the heat dissipation ability to cool the body, and the shell body forms the second heat dissipation operation.

[0026] The outside of the shell is covered with an insulation sleeve, the interior of the insulation sleeve is hollowed out to form an installation cavity, and the shell is installed inside the installation cavity, which prevents the user from directly contacting the shell. At this time, the insulation sleeve forms a third heat dissipation operation.

[0027] It should be noted that a ventilation slot is formed in the bottom of the heat insulation sleeve, which is connected to the installation cavity to dissipate heat from the bottom of the shell. At the same time, heat dissipation holes are provided on the left and right side walls of the heat insulation sleeve, which are distributed on the side walls and are connected to the installation cavity to dissipate heat from the side walls of the shell.

[0028] Furthermore, the ventilation slots on both sides extend upward and penetrate the side walls of the insulation sleeve, the top of the ventilation slots is higher than the bottom end surface of the insulation sleeve, and the ventilation slots are interconnected with the heat dissipation holes through the installation cavity. According to the physical principle that hot air rises, cold air enters the installation cavity through the ventilation slots and is discharged through the heat dissipation holes, thereby forming an effective air flow, promoting the rise of hot air and the entry of cold air, enhancing the heat dissipation effect of the shell, avoiding overheating of the shell, and also reducing the internal temperature of the toaster to a certain extent, avoiding safety accidents caused by internal overheating, thereby improving the stability and service life of the toaster.

[0029] In the above-mentioned insulation sleeve, the front and rear ends are designed to be open respectively, and the control device is built into the opening. The user can easily operate the control device through the opening to adjust the baking settings without worrying about the inconvenience caused by adding the insulation sleeve.

[0030] Furthermore, the insulation sleeve can be made of plastic material or insulation cotton board. The flexible selection of materials meets the needs of different consumers and is suitable for use in various types of toasters.

[0031] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
