At the same time, the automatic removal of the baking tray can effectively improve the safety of taking out food and the baking tray, thereby facilitating people's use and operation. The steam oven has a simple structural design, is convenient and easy to use and operate, and is stable and reliable. Its performance can meet people's use needs. However, the patent still has the following problems in actual use:

[0004] Although the device for automatically adjusting the air volume of the multi-purpose steam oven can realize the functions of automatic air volume adjustment and automatic removal of the baking tray, it cannot realize air volume circulation, resulting in high-temperature steam and the heating tube being directly blown onto the food surface at the top of the steam oven, thereby causing uneven heating of the food at the top, which easily leads to the phenomenon that the food is burnt on the outside and raw on the inside. At the same time, when taking food out, a large amount of steam and heat will overflow from the top of the oven door, which can easily scald the user, which is not conducive to the safety of using the steam oven.

[0005] Therefore, a multi-purpose steam oven with an automatic air volume adjustment structure is proposed to solve the above-mentioned problems. Summary of the invention

[0006] The object of the present invention is to provide a universal steam oven with an automatic air volume adjustment structure, so as to solve the problems raised in the above background technology that the air volume cannot be circulated, resulting in high-temperature steam and heating tubes directly blowing onto the food surface at the top of the steam oven, thus causing uneven heating of the food at the top, prone to the phenomenon of the food being charred on the outside and raw on the inside.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: For the universal steam oven with an automatically adjustable air volume structure, the weight of the food itself drives the baking tray bracket and the telescopic sliding sleeve to descend. At the same time, under the action of the rotating rod connected to the bottom of the baking tray bracket, the first rotating plate and the second rotating plate rotate around the rotating connection shaft, so that the circulating air outlet can be opened. The rotation angles of the first rotating plate and the second rotating plate can be controlled according to the weight of the steamed or roasted food, facilitating the adjustment of the opening size of the circulating air outlet, thereby controlling the air volume of the circulating air, facilitating the automatic adjustment of the air volume, and thus realizing the uniform steaming and roasting of the food. By pulling the end of the fixed bolt and squeezing the fixed spring, the fixed bolt is separated from the fixed hole. At the same time, by pressing down the handle, under the action of the second hinge, the anti-scald air release cover is tilted up, and the high-temperature steam and heat inside the oven body are discharged to the top side of the oven body under the action of the anti-scald air release cover. Under the action of the anti-scald air release cover, the high-temperature steam and heat can be prevented from blowing towards the user, thus avoiding the phenomenon of scalding. The specific content is as follows:

[0022] 1. By setting up the circulation adjustment mechanism, not only can a certain suction force be generated by the circulation fan inside the top of the circulation air duct, sucking the heat and hot steam at the top into the interior of the circulation air duct through the air inlet elbow and discharging them through the circulating air outlet, facilitating the circulation of heat, thereby improving the uniform heating effect of the steam oven. When the circulation fan is working, the sealed rotating plate inside the sealed bracket is affected by the suction force and rotates to a horizontal state under the action of the sealed rotating sleeve, facilitating the circulation of heat. When the circulation fan stops working, under the action of the torsion spring, the sealed rotating plate returns to the vertical state, enabling the sealed rotating plate to be connected end to end, and at the same time, the sealed bracket is closed by the sealed baffle, facilitating the circulation of air volume. When steaming or roasting food, insert the steaming or roasting baking tray containing the food into the baking tray bracket. The weight of the food itself drives the baking tray bracket and the telescopic sliding sleeve to descend. At the same time, under the action of the rotating rod connected to the bottom of the baking tray bracket, the first rotating plate and the second rotating plate rotate around the rotating connection shaft, so that the circulating air outlet can be opened. The rotation angles of the first rotating plate and the second rotating plate can be controlled according to the weight of the steamed or roasted food, facilitating the adjustment of the opening size of the circulating air outlet, thereby controlling the air volume of the circulating air, facilitating the automatic adjustment of the air volume, and thus realizing the uniform steaming and roasting of the food, improving the taste of the steamed or roasted food. By setting multiple steaming or roasting baking trays and circulating air outlets, the air volume of each layer of food can be automatically adjusted, thereby realizing the uniform heating of multiple layers of food, enabling each layer of food to be uniformly heated, and avoiding the phenomenon that the air volume directly blows towards the top food, resulting in the outer part of the top food being charred and the inner part being undercooked, affecting the uniformity of food heating;

[0023] 2. By setting up the air volume adjustment mechanism, not only can the blower inside the hair dryer be used to blow air into the interior of the oven body, but also the adjustment motor can be started to drive the rotation of the adjustment driving bevel gear. Utilizing the meshing connection between the adjustment driving bevel gear and the meshing bevel gear ring, the rotation of the meshing bevel gear ring can be achieved. By using the meshing connection between the meshing bevel gear ring and the adjustment driven bevel gear, the rotation of the adjustment driven bevel gear can be realized. Under the action of the rotating support disc and the rotating support column, the adjustment driving bevel gear and the adjustment driven bevel gear drive the rotating flap to rotate. By adjusting the inclination angle between the rotating flaps, it is convenient to control the air volume output of the hair dryer, and the air volume can be adjusted according to the properties of the food to be steamed and baked, thereby improving the effect of food steaming and baking. When taking out the steamed and baked food, since there will be a large amount of high-temperature steam and heat inside the oven body, when opening the oven door, the high-temperature steam and heat inside the oven body will gush out, and it is very easy to cause scalding. By pulling the end of the fixed bolt and squeezing the fixed spring, the fixed bolt is separated from the fixed hole. At the same time, by pressing down the handle, under the action of the second hinge, the heat insulation and air release cover will tilt up. The high-temperature steam and heat inside the oven body will be discharged towards the top side of the oven body under the action of the heat insulation and air release cover. Under the action of the heat insulation and air release cover, the high-temperature steam and heat can be prevented from blowing towards the user, thus avoiding scalding. When the high-temperature steam and heat are discharged, under the action of the first hinge, the oven door can be opened, which is convenient for taking out the steamed and baked food and improves the safety of using the steam oven.

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figures 1-11, the present invention provides a technical solution: a universal steam oven with an automatically adjustable air volume structure, including a circulation adjustment mechanism 1 and a steam baking tray 116 installed inside the circulation adjustment mechanism 1. An air volume adjustment mechanism 2 is arranged outside the circulation adjustment mechanism 1, and a blowing cylinder 205 is fixedly installed at the top of the air volume adjustment mechanism 2. The circulation adjustment mechanism 1 includes a mounting bracket 101, and circulation air ducts 102 are symmetrically installed inside the mounting bracket 101. A first fan bracket 103 is fixedly installed on the inner side of the top of the circulation air duct 102. Among them, a circulation fan 104 is fixedly installed inside the first fan bracket 103. An air inlet elbow 105 is fixedly installed at the top of the circulation air duct 102. Among them, a sealing bracket 106 is fixedly installed at the end of the air inlet elbow 105. Sealing baffles 107 are fixedly installed both above and below inside the sealing bracket 106. A number of sealing rotating sleeves 108 are rotatably connected inside the sealing bracket 106. A sealing rotating plate 109 is fixedly installed at the top of the sealing rotating sleeve 108. A torsion spring 110 is fixedly installed inside the sealing rotating sleeve 108. The sealing rotating plates 109 are connected end to end. Using the circulation fan 104 on the inner side of the top of the circulation air duct 102 to generate a certain suction force, the heat and hot steam at the top are inhaled into the inside of the circulation air duct 102 through the air inlet elbow 105 and discharged through the circulation air outlet 121, facilitating the circulation of heat, thereby improving the uniform heating effect of the steam oven. When the circulation fan 104 is working, the sealing rotating plate 109 inside the sealing bracket 106 is affected by the suction force and rotates to the horizontal state under the action of the sealing rotating sleeve 108, facilitating the circulation of heat. When the circulation fan 104 stops working, under the action of the torsion spring 110, the sealing rotating plate 109 returns to the vertical state, enabling the sealing rotating plates 109 to be connected end to end, and at the same time, the sealing bracket 106 is closed by the sealing baffle 107, facilitating the circulation of air volume.

[0038] On the inner side of the installation bracket 101, a number of telescopic sliding grooves 111 are provided. Inside the telescopic sliding grooves 111, telescopic sliding rods 112 are fixedly installed. On the outer side of the telescopic sliding rods 112, telescopic sliding sleeves 113 are slidably connected. At the bottom of the telescopic sliding sleeves 113, support springs 114 are fixedly installed. On one side of the telescopic sliding sleeves 113, baking tray brackets 115 are fixedly installed. The steaming and baking tray 116 is slidably connected to the baking tray bracket 115. On both sides of the bottom of the baking tray bracket 115, connecting rotating rods 117 are symmetrically and rotatably connected. At the bottom of the connecting rotating rods 117, first rotating plates 118 are rotatably connected. At the bottom of the first rotating plates 118, rotating connecting shafts 119 are fixedly installed. At the bottom of the rotating connecting shafts 119, second rotating plates 120 are fixedly installed. On the outer side of the rotating connecting shafts 119, circulating air outlets 121 are rotatably connected. The circulating air outlets 121 are fixedly installed on one side of the circulating air duct 102. When steaming and baking food, insert the steaming and baking tray 116 containing food into the baking tray bracket 115. The weight of the food itself drives the baking tray bracket 115 and the telescopic sliding sleeve 113 to descend. At the same time, under the action of the connecting rotating rods 117 at the bottom of the baking tray bracket 115, the first rotating plate 118 and the second rotating plate 120 rotate around the rotating connecting shaft 119, so that the circulating air outlets 121 can be opened. The rotation angles of the first rotating plate 118 and the second rotating plate 120 can be controlled according to the weight of the steamed and baked food, facilitating the adjustment of the opening size of the circulating air outlets 121, thereby controlling the air volume of the circulating air, facilitating the automatic adjustment of the air volume, and thus realizing the uniform steaming and baking of food, improving the taste of the steamed and baked food. By setting multiple steaming and baking trays 116 and circulating air outlets 121, the air volume of each layer of food can be automatically adjusted, so as to realize the uniform heating of multiple layers of food, enabling each layer of food to be uniformly heated, avoiding the phenomenon that the air volume directly blows on the top food, resulting in the top food being charred on the outside and raw on the inside, and affecting the uniformity of food heating.

[0039] The air volume regulating mechanism 2 includes an oven body 201. Mounting brackets 101 are symmetrically installed on both inner sides of the oven body 201. An oven base 202 is fixedly installed at the bottom of the oven body 201. A steam generator 203 is fixedly installed at the center of the top of the oven base 202. A heating pipe 204 is fixedly installed on the inner side of the top of the oven body 201. A blower tube 205 is fixedly installed on the top of the oven body 201 near the heating pipe 204. A connecting pipe 206 is fixedly installed on the back of the blower tube 205, and the connecting pipe 206 is fixedly installed on the top of the oven body 201. A second fan bracket 207 is fixedly installed on the inner side of the top of the blower tube 205. A blower 208 is fixedly installed inside the second fan bracket 207. An adjusting motor 209 is fixedly installed on one side inside the blower tube 205. The output end of the adjusting motor 209 is fixedly connected to an adjusting driving bevel gear 210. The bottom of the adjusting driving bevel gear 210 is meshed with a meshing bevel gear ring 211. The top of the meshing bevel gear ring 211 is meshed with a number of adjusting driven bevel gears 212. One side of both the adjusting driving bevel gear 210 and the adjusting driven bevel gears 212 is fixedly installed with a rotating flap 213. The center of the rotating flap 213 is rotatably connected to a rotating support disc 214. A rotating support column 215 is fixedly installed at the bottom of the rotating support disc 214. The blower 208 inside the blower tube 205 is used to blow air into the oven body 201. At the same time, the adjusting motor 209 is started to drive the adjusting driving bevel gear 210 to rotate. Due to the meshing connection between the adjusting driving bevel gear 210 and the meshing bevel gear ring 211, the rotation of the meshing bevel gear ring 211 can be realized. Due to the meshing connection between the meshing bevel gear ring 211 and the adjusting driven bevel gears 212, the rotation of the adjusting driven bevel gears 212 can be realized. Under the action of the rotating support disc 214 and the rotating support column 215, the adjusting driving bevel gear 210 and the adjusting driven bevel gears 212 drive the rotating flap 213 to rotate. By adjusting the inclination angle between the rotating flaps 213, it is convenient to control the air volume output from the blower tube 205, and the air volume can be adjusted according to the properties of the food to be steamed and baked, so as to improve the effect of steaming and baking the food.

[0040] The rotating support column 215 is fixedly installed at the top of the oven body 201. Fixing holes 216 are symmetrically formed on the front surface of the top of the oven body 201. First hinges 217 are symmetrically installed on the front surface of the bottom of the oven body 201. The tops of the two first hinges 217 are rotatably connected to an oven door 218. Second hinges 219 are symmetrically installed on the top of the oven door 218. The tops of the two second hinges 219 are rotatably connected to a heat-insulating air-release cover 220. Fixed bolts 221 are symmetrically and slidably connected inside the heat-insulating air-release cover 220. The fixed bolts 221 are snap-connected to the oven body 201 through the fixing holes 216. A fixed spring 222 is fixedly installed at the end of the fixed bolt 221. A handle 223 is fixedly installed on one side of the fixed spring 222. The handle 223 is fixedly installed on the outside of the heat-insulating air-release cover 220. When taking out the steamed and roasted food, since there will be a large amount of high-temperature steam and heat inside the oven body 201, when the oven door 218 is opened, the high-temperature steam and heat inside the oven body 201 will gush out, and it is very easy to cause scalding. By pulling the end of the fixed bolt 221 and squeezing the fixed spring 222, the fixed bolt 221 is separated from the fixing hole 216. At the same time, the handle 223 is pressed downward. Under the action of the second hinge 219, the heat-insulating air-release cover 220 tilts up. The high-temperature steam and heat inside the oven body 201 are discharged to the top side of the oven body 201 under the action of the heat-insulating air-release cover 220. Under the action of the heat-insulating air-release cover 220, the high-temperature steam and heat can be prevented from blowing towards the user, thus avoiding scalding. After the high-temperature steam and heat are discharged, the oven door 218 can be opened under the action of the first hinge 217, facilitating the taking out of the steamed and roasted food and improving the use safety of the steam oven.

[0041] Working principle: Before using the universal steam oven with an automatically adjustable air volume structure, it is necessary to first check the overall situation of the device to ensure that it can work normally. According to Figure 1 - Figure 11As shown in the figure, first, when steaming and baking food, insert the steaming and baking baking tray 116 containing the food into the baking tray bracket 115. The weight of the food itself drives the baking tray bracket 115 and the telescopic sliding sleeve 113 to descend. At the same time, under the action of the rotating rod 117 connected to the bottom of the baking tray bracket 115, the first rotating plate 118 and the second rotating plate 120 rotate around the rotating connection shaft 119, so that the circulating air outlet 121 can be opened. The rotation angles of the first rotating plate 118 and the second rotating plate 120 can be controlled according to the weight of the steamed and baked food, which is convenient for adjusting the opening size of the circulating air outlet 121, thereby controlling the air volume of the circulating air, facilitating the automatic adjustment of the air volume, and thus realizing the uniform steaming and baking of the food, improving the taste of the steamed and baked food. By setting multiple steaming and baking baking trays 116 and circulating air outlets 121, the air volume of each layer of food can be automatically adjusted, so as to realize the uniform heating of multiple layers of food, enable each layer of food to be uniformly heated, avoid the air volume directly blowing on the top food, causing the phenomenon of the top food being charred on the outside and raw on the inside, and affecting the uniformity of food heating.

[0042] Secondly, the circulating fan 104 inside the top of the circulating air duct 102 generates a certain suction force, sucks the heat and hot steam at the top into the inside of the circulating air duct 102 through the air inlet elbow 105, and discharges them through the circulating air outlet 121, which is convenient for heat circulation, thereby improving the uniform heating effect of the steam oven. When the circulating fan 104 is working, the sealing rotating plate 109 inside the sealing bracket 106 is affected by the suction force and rotates to a horizontal state under the action of the sealing rotating sleeve 108, which is convenient for heat circulation. When the circulating fan 104 stops working, under the action of the torsion spring 110, the sealing rotating plate 109 returns to the vertical state, which can realize the end-to-end connection of the sealing rotating plate 109. At the same time, the sealing bracket 106 is closed by the sealing baffle 107, which is convenient for air volume circulation.

[0043] Finally, use the blower 208 inside the hair dryer 205 to blow air into the interior of the oven body 201. At the same time, start the adjustment motor 209 to drive the rotation of the adjustment driving bevel gear 210. Utilizing the meshing connection between the adjustment driving bevel gear 210 and the meshing bevel gear ring 211, the rotation of the meshing bevel gear ring 211 can be achieved. Utilizing the meshing connection between the meshing bevel gear ring 211 and the adjustment driven bevel gear 212, the rotation of the adjustment driven bevel gear 212 is realized. Under the action of the rotating support disk 214 and the rotating support column 215, the adjustment driving bevel gear 210 and the adjustment driven bevel gear 212 drive the rotating flap 213 to rotate. By adjusting the inclination angle between the rotating flaps 213, it is convenient to control the air volume output of the hair dryer 205, and the air volume can be adjusted according to the nature of the food to be steamed and baked, thereby improving the effect of steaming and baking the food. When taking out the steamed and baked food, since there will be a large amount of high-temperature steam and heat inside the oven body 201, when opening the oven door 218, the high-temperature steam and heat inside the oven body 201 will gush out, and it is very easy to cause scalding. By pulling the end of the fixed bolt 221 and squeezing the fixed spring 222, the fixed bolt 221 is separated from the fixed hole 216. At the same time, press down the handle 223. Under the action of the second hinge 219, the anti-scald air release cover 220 is lifted. The high-temperature steam and heat inside the oven body 201 are discharged to the top side of the oven body 201 under the action of the anti-scald air release cover 220. Under the action of the anti-scald air release cover 220, the high-temperature steam and heat can be prevented from blowing towards the user, thus avoiding scalding. After the high-temperature steam and heat are discharged, under the action of the first hinge 217, the oven door 218 can be opened, which is convenient for taking out the steamed and baked food and improves the safety of using the steam oven.
