Description

Technical Field

[0001] The utility model relates to the technical field of ovens, in particular to an oven with a heat dissipation function. Background Art

[0002] The oven is an electrical appliance that we often use in our daily life. The inner tank is an important component of the oven. The inner tank will generate high temperature when working, which will cause the temperature inside the oven to rise and the surface temperature of the door panel to rise. Long-term use will reduce the service life of the oven. Therefore, it is necessary to cool the inside of the oven, discharge the high-temperature gas from the oven without affecting the normal use of the oven, and cool the door panel at the same time. However, the structure in the prior art has poor heat dissipation effect on the inner tank and the door panel. Utility Model Content

[0003] The utility model provides an oven and a steam oven with a heat dissipation function, which solves the problem of poor heat dissipation effect of an inner tank and a door panel in the prior art.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] Oven with heat dissipation function, including

[0006] A main body, wherein an inner liner is installed in the main body;

[0007] A door panel, which is hingedly mounted on the opening end of the inner liner;

[0008] A heat dissipation fan, which is arranged on the upper end surface of the inner tank;

[0009] A smoke collecting hood is arranged on one side of the heat dissipation fan;

[0010] The characteristics are as follows: a heat dissipation hood is provided on the back of the inner pot, and the heat dissipation hood covers the heat dissipation fan. When the oven is working, the high-temperature gas generated inside can be more effectively discharged. The heat dissipation hood is connected to the inner pot through a mounting plate, which ensures the stability of the structure and is convenient for installation and disassembly. Two sections of smoke channels are formed between the heat dissipation hood, the smoke collecting hood and the surface of the inner pot. The heat dissipation fan drives the gas to pass through the smoke channel and the door panel until the high-temperature gas is taken away from the oven to achieve heat dissipation.

[0011] Furthermore, an air inlet is provided below the heat dissipation hood, and the air inlet is connected to the smoke channel, so that the heat dissipation fan can suck the cold air outside the oven through the air inlet.

[0012] Furthermore, a maintenance cover is provided on the surface of the heat sink hood, which is communicated with the interior of the heat sink hood, providing a convenient access for maintenance and repair of the internal components of the heat sink hood. The maintenance cover is a part that can be opened or removed, allowing engineers or maintenance personnel to directly access the internal structure of the heat sink hood. When the heat sink hood or internal components fail or require regular maintenance, the presence of the maintenance cover greatly simplifies the maintenance process. Maintenance personnel do not need to completely disassemble the heat sink hood, but only need to open or remove the maintenance cover to inspect, replace or repair the internal components. This not only improves maintenance efficiency, but also reduces maintenance costs and maintenance time.

[0013] Furthermore, a temperature-averaging motor is provided in the heat dissipation hood. The temperature-averaging motor is used to maintain the internal temperature of the constant temperature inner tank. The temperature control of the oven inner tank is very important. Too high or too low temperature may affect the performance of the equipment or the quality of the product. Therefore, the introduction of the temperature-averaging motor is to ensure that the internal temperature of the inner tank is maintained within the set range, thereby ensuring the normal operation of the equipment and the quality of the product.

[0014] Furthermore, a heat dissipation fan upper plate is installed on the upper end surface of the smoke hood, and an air flow channel is formed inside the heat dissipation fan upper plate. The air flow channel connects two sections of smoke channels. The two sections of smoke channels are connected through the heat dissipation fan upper plate, so that the heat dissipation fan can inhale cold air from the outside and discharge the high-temperature gas to the outside of the oven after passing through the smoke channel.

[0015] Furthermore, the smoke hood includes a rapid flow portion and a heat dissipation portion. The cross-sectional area of ​​the rapid flow portion is smaller than that of the heat dissipation portion. The rapid flow portion is the entrance portion of the smoke hood and has a smaller cross-sectional area. This design causes the high-temperature smoke entering the smoke hood to be compressed to a certain extent in the rapid flow portion, thereby accelerating the flow velocity of the airflow. This acceleration effect helps to better draw the high-temperature smoke into the smoke hood, and also helps to reduce the turbulence and eddy current of the airflow in the smoke hood, making the airflow smoother. The heat dissipation portion is the exit portion of the smoke hood and has a larger cross-sectional area. This design allows the airflow to diffuse when passing through the heat dissipation portion, reducing the flow velocity and increasing the contact area with the upper end surface of the inner tank, which helps to reduce the surface temperature of the inner tank. The design of the heat dissipation portion also helps to reduce the noise of the airflow during discharge, thereby improving the comfort of using the smoke hood.

[0016] Furthermore, a circulation port is provided on the side of the main body close to the door panel, and an air outlet is provided on the side of the smoke hood away from the heat dissipation fan. The air outlet is connected to the circulation port. The existence of the circulation port allows air to flow freely between the inside and outside of the smoke hood. Through the design of the circulation port and the air outlet, the hot air inside the smoke hood can be quickly discharged through the air outlet, thereby achieving efficient heat dissipation. The connectivity of the circulation port and the air outlet allows the air inside and outside the smoke hood to be exchanged smoothly, effectively preventing air accumulation and vortex formation, and improving the ventilation effect.

[0017] Furthermore, a heat dissipation channel is provided through the door panel from top to bottom, and the circulation port is communicated with the heat dissipation channel. Effective heat dissipation is achieved through the heat dissipation channel that runs through from top to bottom. This design allows the heat generated inside the door panel to be quickly discharged through the heat dissipation channel, avoiding heat accumulation inside the door panel, thereby maintaining the temperature of the door panel stable. The design of the heat dissipation channel also takes into account the need for air circulation. The circulation port is communicated with the heat dissipation channel, so that external air can smoothly enter the heat dissipation channel, further promoting heat dissipation. This design not only improves the heat dissipation efficiency, but also helps to keep the surface of the door panel clean and prevent the accumulation of dust and dirt.

[0018] Furthermore, the heat dissipation channels are evenly arranged to ensure that the heat dissipation channels are evenly distributed around the heat source to maximize the heat dissipation efficiency.

[0019] The utility model has the following beneficial effects due to the adoption of the above technical solution:

[0020] The utility model has an oven with a heat dissipation function, and a heat dissipation hood is provided on the back of the inner tank, and the heat dissipation hood covers the heat dissipation fan. When the oven is working, the high-temperature gas generated inside can be more effectively discharged. The heat dissipation hood is connected to the inner tank through a mounting plate, which ensures the stability of the structure and is convenient for installation and disassembly. Two sections of smoke channels are formed between the heat dissipation hood and the surface of the smoke collecting hood and the inner tank. The heat dissipation fan drives the gas to pass through the smoke channel and the door panel until the high-temperature gas is taken away from the oven, thereby improving the heat dissipation effect.

A seal is installed at the connection between the temperature-averaging motor 26 and the mounting plate 19 to prevent leakage of high-temperature gas. The temperature-averaging motor 26 is used to maintain the internal temperature of the constant temperature inner tank 20. The temperature control of the oven inner tank 20 is very important. Too high or too low temperature may affect the performance of the equipment or the quality of the product. Therefore, the introduction of the temperature-averaging motor 26 is to ensure that the internal temperature of the inner tank 20 is maintained within the set range, thereby ensuring the normal operation of the equipment and the quality of the product.
