Description
Technical Field
[0001] The utility model relates to the technical field of ovens, in particular to a hot air oven that prevents heat from escaping. Background Art
[0002] An oven is a device that uses hot air to bake and cook food. It is also called an oven, a baking box, or a baking oven. The use of hot air in an open form is called barbecue. The oven can also be used to refer to a device that uses hot gas for high-temperature treatment. Fan blades and other structures are set inside the oven, which can work during heating to make the hot air circulate inside the oven, which has a better and more uniform heating effect on the food.
[0003] When using pork to produce and process snack foods, after the pork is processed and marinated, it needs to be processed in a hot air oven. Due to the large processing volume, it is generally operated by adding and taking out in batches. When adding or taking out, the oven door is in an open state, which easily causes heat to escape and increase energy consumption. Therefore, we propose a hot air oven that prevents heat from escaping. Utility Model Content

[0025] See also Figure 1-2 The utility model provides a technical solution: a hot air oven for preventing heat dissipation, comprising a box body 1 and a drawer 2. The front end surface of the box body 1 is evenly provided with a plurality of through-holes 11, each of which is communicated with the interior of the box body 1. There are 4 through-holes 11, or a suitable number according to needs, and the number of drawers 2 is kept the same as the number of through-holes 11. The drawer 2 is inserted into the box body 1 through the through-holes 11. A mesh plate 23 is horizontally fixed inside the drawer 2. The pork to be baked is placed above the mesh plate 23 in the drawer 2, and then the drawer 2 is pushed into the interior of the box body 1.
[0026] A baffle 21 is fixed at the front end of the drawer 2. The size of the baffle 21 is larger than the size of the opening 11. When the drawer 2 is fully pushed in, the baffle 21 touches the outer surface of the box body 1 and blocks the opening 11. A handle 211 is welded and fixed on the surface of the baffle 21. The handle 211 is located in the middle of the surface of the baffle 21. The baffle 21 can be pulled by the handle 211 to pull the drawer 2 out or push it back.
[0027] A plurality of electric heating tubes 3 are installed at the upper left side and the lower right side of the box body 1. A fan blade 311 is rotatably installed on the inner surface of the box body 1 at the electric heating tube 3. The fan blade 311 is placed between the electric heating tube 3 and the inner wall of the box body 1. A motor 31 is installed on the outer surface of the box body 1 at the fan blade 311. The motor 31 is transmission-connected to the fan blade 311. When baking, the motor 31 and the electric heating tube 3 are started to make the electric heating tube 3 heat the air inside the box body 1. Then, under the action of the fan blade 311, a counterclockwise air circulation is formed to bake the pork placed in the drawer 2. In addition, the upper fan blade 311 and the electric heating tube 3 can be set on the right side, while the lower fan blade 311 and the electric heating tube 3 can be set on the left side, thereby forming a clockwise hot air circulation.
[0028] Support legs 12 are fixed to the four corners of the bottom of the box body 1. There are four support legs 12. The height of the support legs 12 is greater than the thickness of the motor 31. The support legs 12 support the height of the box body 1 to prevent the bottom motor 31 from contacting the ground.
[0029] A sealing plate 22 placed in the box body 1 is fixed at the end of the drawer 2. The size of the sealing plate 22 is larger than the size of the through-opening 11, and a ring frame 111 is fixed around the inside of the box body 1 on the outer circle of the through-opening 11. The inner size of the ring frame 111 is slightly larger than the outer size of the sealing plate 22. When the drawer 2 is pulled out, the sealing plate 22 enters the ring frame 111 and can seal it, thereby sealing the through-opening 11. When the drawer 2 is pulled out, it can prevent hot air from escaping from the through-opening 11 and causing additional energy consumption.
[0030] Guide rods 112 are connected and fixed in the box body 1 on both sides of the drawer 2. The guide rods 112 on both sides are parallel to each other. The guide rods 112 can slidably pass through the surfaces of the closing plates 22 on both sides of the drawer 2. Guide holes 221 are opened on the surfaces of the closing plates 22 on both sides. The guide rods 112 can slidably pass through the closing plates 22 through the guide holes 221. When the drawer 2 is pulled out, the guide holes 221 can cooperate with the guiding and limiting function of the guide rods 112.
[0031] When in use, the drawer 2 is pulled out by pulling the handle 211, and the processed pork is placed above the mesh plate 23 in the drawer 2, and then the drawer 2 is pushed back, the baffle 21 blocks the through hole 11 and the box body 1 is blocked, and then the upper and lower motors 31 and the electric heating tube 3 are started. The electric heating tube 3 works to heat the air, which is then blown by the fan blades 311 to form a counterclockwise circulating hot air flow inside the box body 1, which serves the purpose of hot air baking for the pork. After the pork in a certain drawer 2 is baked, the handle 211 at the front end of the drawer 2 is pulled separately to draw the drawer 2 out of the box body 1 until the sealing plate 22 at the rear end of the drawer 2 is pulled into the inside of the ring frame 111, thereby achieving the blocking of the through hole 11. At this time, the hot air flow inside the box body 1 can continue to circulate without affecting the baking of other pork, and then the pork drawn out to the surface of the mesh plate 23 in the external drawer 2 can be taken away, and new pork can be replaced and pushed into the box body 1 again for baking.
