Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ovens, in particular to an oven with self-processing smoke. Background Art
[0002] In daily life, barbecue is favored by many people as a leading summer food. However, when grilling outdoors, unstable wind direction will cause the flames to sway, which in turn affects the uniformity of heating in the oven. If the air vent of the oven is directly facing the wind, the heat source will be unstable, causing the food to be heated unevenly. Uneven heating will cause different parts of the food to taste completely different. One side may have been roasted too dry and hard, while the other side may still retain a raw taste. The over-scorched part may produce harmful substances, and the undercooked part may pose a safety hazard, such as bacteria not being completely killed, thus affecting the safety of the food. Utility Model Content
[0003] The purpose of the utility model is to solve the shortcomings of the prior art, that is, the unstable heat source affects the safety of food and the oil smoke damages the drainage fan after long-term operation, and to propose a smoke self-processing oven.
[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0005] A smoke self-processing oven is designed, comprising a oven body, a heating element fixedly connected to the inside of the oven body, a water tank slidably connected to the lower part of the oven body, an air pipe fixedly connected to the outside of the oven body, a drainage fan fixedly connected to the inside of the air pipe, and a heat flow gathering mechanism jointly provided at the end of the air pipe and the oven body.
[0006] Preferably, the heat flow gathering mechanism includes a gas flow tube, which extends to the outside of the furnace body and is jointly provided with a quantitative water discharge mechanism at the end of the gas tube. Multiple groups of blowing holes are opened on the inside of the furnace body, and the blowing holes are connected to the gas flow tube.
[0007] Preferably, the blowing hole is conical in shape.
[0008] Preferably, the quantitative water discharge mechanism includes a box body, the top of the box body is connected to the gas flow pipe, the outside of the box body is connected to the air pipe, the bottom of the box body is fixedly connected to a box cover, the inside of the box body is fixedly connected to a return spring, the end of the return spring is fixedly connected to the box cover, the outside of the box body is fixedly connected to a first magnet, the top of the box cover is fixedly connected to a second magnet, and the first magnet and the second magnet are adsorbed to each other.
[0009] Preferably, a sealing ring is fixedly connected to the lower inner side of the box body.
[0010] Preferably, a filter screen is fixedly connected to the end of the trachea.
[0011] Preferably, the air pipe is shaped as a reducer, characterized by an eccentric reducer.
[0012] The utility model proposes a self-smoking oven with smoke treatment, which has the beneficial effect of: the oven draws the remaining smoke into the air pipe through the drainage fan, and then transports the fast-flowing gas to the blowing hole through the gas flow generated by the drainage fan and the gas flow pipe, so that the hot air generated by the electric heating element is gathered in the middle, thereby controlling the heat flow, improving the unstable heat source, avoiding the uncertainty of food being raw or cooked, and thus causing problems such as taste and food safety. By changing the position of the electric heating element and utilizing the water storage drawer to catch grease, the generation of grease smoke is reduced, and the remaining smoke is filtered through the filter net, reducing the impact of oil smoke on the drainage fan, thereby improving the overall working efficiency of the oven.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0019] Example 1
[0020] Reference Figure 1-4A smoke self-processing oven includes a furnace body 1, a heating element 8 is fixedly connected to the inside of the furnace body 1, a water tank 2 is slidably connected to the bottom of the furnace body 1, an air pipe 3 is fixedly connected to the outside of the furnace body 1, a drainage fan 7 is fixedly connected to the inside of the air pipe 3, and a heat flow gathering mechanism is jointly provided at the end of the air pipe 3 and the furnace body 1.
[0021] The heat flow gathering mechanism includes a gas flow tube 5, which extends to the outside of the interior of the furnace body 1 and is jointly provided with a quantitative water discharge mechanism at the end of the gas pipe 3. Multiple groups of blowing holes 6 are opened on the inside of the furnace body 1, and two rows of multiple groups of blowing holes 6 are connected to the gas flow tube 5. The opening of the end where the blowing holes 6 are connected to the gas flow tube 5 is large, and the opening of the end where the blowing holes 6 are opened on the inside of the furnace body 1 is small. When the gas passes through a gradually narrowing channel, its flow rate will increase.
[0022] The multiple groups of blowing holes 6 are conical in shape. The blowing holes 6 are located directly above the heating element and are arranged in two rows of blowing holes 6, which can better gather the hot air to the middle.
[0023] During actual use, the heating element 8 first heats the grill above the stove body 1. When food is placed on the stove body 1, smoke is generated. Then the ventilation fan 7 is started, and the ventilation fan 7 will suck the smoke into the air pipe 3. The air pipe 3 then transports the filtered airflow to the gas flow tube 5, and the gas flow tube 5 will discharge the airflow from the blowing hole 6. With the increase in the flow rate of the ventilation fan 7 and the two rows of conical blowing holes 6, the airflow will gather the heat generated by the heating element 8 to the middle, avoiding the instability of the heat source, causing uneven heating of the food, and improving the taste and safety of the food.
[0024] Example 2
[0025] The mist in the smoke is produced by the vaporization of the food or its own water. When it is inhaled into the trachea 3, it will release heat and turn into water that accumulates in the trachea 3, affecting the work of the trachea 3. Figure 4 As another preferred embodiment of the present invention, on the basis of embodiment 1, it also includes a quantitative water discharge mechanism including a box body 9, which is located above the water tank 2 to facilitate the water after discharge to fall into it, the top of the box body 9 is connected with the gas flow pipe 5, the outside of the box body 9 is connected with the air pipe 3, the bottom of the box body 9 is fixedly connected with a box cover 12, the box body 9 and the box cover 12 are connected by a hinge, and a return spring 14 is fixedly connected to the inside of the box body 9. The return spring 14 is selected with a weak elastic force, which does not affect the opening of the box cover 12, and its elastic force is only enough to pull the box cover 12 back. The end of the return spring 14 is fixedly connected to the box cover 12, the outside of the box body 9 is fixedly connected with a first magnet 10, and the top of the box cover 12 is fixedly connected with a second magnet 11. The first magnet 10 and the second magnet 11 are attracted to each other, and the box cover 12 is fixed to the bottom of the box body 9 by the suction force of the two magnets.
[0026] A sealing ring 13 is fixedly connected to the lower inner side of the box body 9. By adding the sealing ring 13, the sealing performance is increased in the case of no drainage, thereby avoiding affecting the gas flow rate in the air pipe 3.
[0027] During use, the mist is re-liquefied by releasing heat and flows from the air pipe 3 to the inside of the box body 9 with the air flow. Because the weight of the liquid is greater than that of the gas, the liquid will not continue to flow with the air flow and will accumulate at the bottom of the box body 9. When the weight of the water accumulated at the bottom is greater than the suction force between the first magnet 10 and the second magnet 11, the box cover 12 will be clamped from the bottom of the box body 9 to drain the water into the water tank 2. After the discharge is completed, there is no water pressure, and the box cover 12 will rebound to the bottom of the box body 9 with the help of the elastic force of the return spring 12. The first magnet 10 and the second magnet 11 will continue to adsorb and wait for the next time the water accumulates to a certain weight. This can not only discharge the water out of the air pipe 3, but also reduce the impact on the gas flow rate during the drainage process, thereby avoiding affecting the normal operation of the air pipe 3, and also ensuring that the blowing hole 6 gathers the hot air, thereby improving the working efficiency of the furnace body 1.
[0028] Example 3
[0029] The oil heats up and evaporates, forming oil smoke, which condenses into small solid particles in the air, which is the smoke we see. The oil smoke has a strong adhesion. At the same time, when the drainage fan 7 rotates at a high speed, the friction between the blades and the air will generate static electricity, which further aggravates the adhesion of small solid particles such as oil smoke to the drainage fan 7, causing damage and affecting the use of the drainage fan 7. Figure 3 As another preferred embodiment of the present invention, based on embodiment 1, a filter screen 4 is fixedly connected to the end of the trachea 3, and a disposable filter oil-absorbing paper is placed on the filter screen 4. A conical placement rod is provided on the filter screen 4, and an annular groove is provided on the filter screen 4 and the connection part thereof to facilitate the replacement of the disposable filter oil-absorbing paper.
[0030] The air pipe 3 is shaped like a reducer and is characterized by an eccentric reducer. When the pipe cross-section is reduced, in order to maintain the same mass flow rate, the flow rate of the fluid will increase. The increase in flow rate makes it easier for the air pipe 3 to allow the inhaled mist to release heat better. The air pipe 3 is made of stainless steel, which facilitates the release of heat from the mist and also prevents corrosion from water vapor, thereby enhancing durability.
[0031] During use, the heating elements 8 are installed on both sides of the furnace body 1 to prevent grease from falling thereon and generating a large amount of smoke. The grease will fall into the water tank 2 at the bottom of the furnace body 1, thereby reducing the generation of oil smoke and reducing the working pressure of the filter 4. After that, the air pipe 3 draws the mist and a small amount of oil smoke into the air pipe 3 through the suction force of the drainage fan 7. The oil smoke will be further absorbed by the disposable filter paper on the filter 4, thereby reducing the oil smoke from entering the air pipe 3 and affecting the working drainage fan 7, thereby improving the working efficiency of the air pipe 3.
[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
