Description

an oven

technical field

The utility model relates to an oven, which belongs to the transformation technology of the oven.

Background technique

The existing oven box 1 is heated by heating pipes arranged in the hollow cavity 11 of the oven box 1 to grill and heat food. The door body 2 is a part that can be touched by the user, therefore, the surface temperature of the door body 2 must meet the requirement. The cooling method that oven door body 2 adopts at present is: door body 2 is provided with the outside window 21 of 3 layers of parallel placements, the window in the door 22, the window in the door 23, between the outside window 21 and the window in the door 22 is provided with the first An air flow channel 24, a second air flow channel 25 is provided between the door window 22 and the door inner window 23, and cold air flows from between the door outer window 21 and the door inner window 22 and between the door inner window 22 and the door inner window 23. The bottom of the air flow passage between them enters, and is discharged at the upper end of the door body 2 through the first and second outer air flow passages driven by the exhaust wind. The top plate of the hollow cavity 11 of the box body 1 is provided with an exhaust motor 3 and an exhaust passage 4. The heat dissipation of the door body is through the gap between the outer window 21 and the middle window 22 of the door and between the window 22 and the inner window of the door. The principle that the air in the air flow channel between the windows 23 is heated and then flows upward is not assisted by external force, so a good heat dissipation effect cannot be achieved. In addition, with this door structure, when the user approaches the oven, the horizontally discharged hot air will blow to the user's face, and the hot air is also accompanied by a little oil fume discharged from the oil fume exhaust hole, which makes the user feel very uncomfortable.

Utility model content

The purpose of the utility model is to consider the above problems and provide an oven with a good heat dissipation effect for the door body. The utility model has reasonable design, and when the user approaches the oven, the hot air discharged horizontally from the door body is prevented from blowing to the user's face.

The technical scheme of the utility model is: the oven of the utility model includes a box body, the box body is provided with a hollow cavity for placing the heating pipe, and the outside of the hollow cavity is provided with a door body, wherein the door body includes an outer window, The window in the door, the window in the door, the first air flow channel is set between the outer window of the door and the window in the door, the second air flow channel is set between the window in the door and the inner window of the door, and the hollow cavity is set in the box An exhaust motor and an exhaust channel are arranged on the top plate of the exhaust motor. The exhaust port of the exhaust motor communicates with the exhaust channel, and the exhaust channel communicates with the first air flow channel and the second air flow channel. A baffle is installed to guide the air in the exhaust passage to the second air flow passage.

The above-mentioned external windows of the door, windows in the door, and internal windows of the door are all glass doors.

Because the utility model adopts the cooling system utilizing the exhaust wind force, the exhaust channel connected with the exhaust motor has a baffle structure on it, and the cold air discharged by the exhaust motor passes through the exhaust channel, and when passing through the upper end of the door body, The baffle guides part of the wind to the second air flow passage provided between the window in the door and the window inside the door, so that the hot air between the window in the door and the window inside the door is discharged from top to bottom, forming an insulating belt for cold air To reduce the temperature rise of the doors and windows. And another part of the wind still drives the hot air between the outer window of the door and the window in the door, and discharges the outside of the oven. Utilize the original exhaust air duct system to guide the air discharged horizontally from the outside of the oven to the inside of the door body. The utilization rate of the exhaust air duct is improved, and the temperature rise of the door is reduced. In addition, the utility model has a reasonable design, and when the user approaches the oven, the hot air discharged horizontally from the door body is prevented from blowing to the user's face. The utility model is a convenient and practical oven with ingenious design and excellent performance.

Detailed ways

Example:

The structural diagram of the utility model is shown in Figure 2, which includes a box body 1, the box body 1 is provided with a hollow cavity 11 for placing a heat pipe, and the outside of the hollow cavity 11 is provided with a door body 2, wherein the door body 2 includes Door outer window 21, door middle window 22, door inner window 23, a first air flow channel 24 is arranged between the door outer window 21 and the door middle window 22, and a first air flow channel 24 is arranged between the door middle window 22 and the door inner window 23. Two air flow channels 25, the top plate of the hollow cavity 11 provided by the casing 1 is provided with an exhaust motor 3 and an exhaust channel 4, the exhaust port of the exhaust motor 3 communicates with the exhaust channel 4, and the exhaust channel 4 It communicates with the first air flow channel 24 and the second air flow channel 25 , wherein the exhaust channel 4 is also equipped with a baffle plate 5 guiding the air in the exhaust channel 4 to the second air flow channel 25 .

In this embodiment, the above-mentioned door outer window 21, door inner window 22, and door inner window 23 are all glass doors.

The working principle of the utility model is as follows: the cold wind discharged by the exhaust motor 3 passes through the exhaust channel 4, and when passing through the upper end of the door body, the baffle plate 5 guides part of the wind to the second air provided between the window in the door and the window inside the door. The flow passage 25 makes the hot air between the door-in-window 22 and the door-in-window 23 discharge from top to bottom, forming a heat-insulating band of cold air to reduce the temperature rise of the door-outside window 21 . And the wind of another part still drives the hot air between the door outer window 21 and the door middle window 22, and discharges the outside of the oven. The utility model utilizes the original exhaust air duct system to guide the wind part discharged horizontally from the outside of the oven to the inside of the door body. The utilization rate of the exhaust air duct is improved, and the temperature rise of the door is reduced.
