Description

Technical Field

[0001] The invention relates to the field of barbecue utensils, in particular to a split multifunctional smokeless electric oven. Background Art

[0002] Electric ovens can grill and cook food, and have the advantages of being clean, small in size, and safe to use. They are now increasingly used in the catering industry and in family life. The invention patent with publication number CN104921616B discloses a portable smokeless electric oven, comprising an oven body 1, an upper cover 2, an electric heating tube device 5, a conical oil receiving box 7 arranged at the lower end of the heating tube 53, an oil outlet hole 71 arranged in the middle of the bottom wall of the oil receiving box 7, and a smoke outlet hole 72 arranged on the upper side wall of the oil receiving box 7; the generated oil smoke is sucked into the oil smoke purification device 92 through the smoke outlet hole 72 by the smoke extraction device 91 for disposal. The invention has the characteristics of novel structure, convenient carrying, easy cleaning, energy saving, environmental protection, smokeless and hygienic. The above patent has the following problems: 1. The furnace body 1 is an integrally formed shell, and a deep storage cavity is formed in the furnace body 1. The upper cover 2, the electric heating tube device 5, the converter 51, the control panel 52, the heating tube 53, the baking tray 6, the oil receiving box 7, the oil receiving tray 8, the smoke extraction device 91, and the oil fume purification device 92 all need to be placed in the furnace body 1. In this way, during installation, since the furnace body is integrated, it is not convenient to assemble these accessories into the furnace body, which affects the assembly efficiency and further affects the production efficiency of the product. 2. Since the oil fume extraction device has a ventilation function, when frying and grilling, the oil fume will be sucked into the shell, and the oil stains will be adsorbed on the inner wall of the shell. With the increase of the use time, the oil stains will accumulate and flow along the inner wall of the shell to the bottom wall of the shell, which makes it more troublesome to clean. 3. The upper cover is inserted into the furnace body horizontally. When grilling, the cover needs to be removed, and when grilling is finished, the cover needs to be covered. The operation is very inconvenient and it is easy to cause damage to the cover.

[0003] The utility model patent with publication number CN217090424 U is the prior patent of the applicant. The patent discloses an electric oven with an oil filter. The patent includes a bottom shell 1, and an installation cavity 11 is arranged in the bottom shell 1. The installation cavity 11 is sequentially provided with a heat insulation plate 4, a heating component 3 and a baking tray 2 from bottom to top. An oil filter 5 and a fan 6 are also arranged in the installation cavity 11. When in use, the fan works and generates suction so that the oil smoke at the upper end of the baking tray enters the installation cavity from the air inlet and passes through the oil filter before being blown out from the air outlet. When the oil smoke passes through the oil filter, grease adheres to the oil filter. Under the action of the fan, the smoke is blown out from the air outlet and the next cycle is carried out again. Grease, dirt, etc. are all adsorbed by the oil filter and will not be adsorbed on the side wall of the installation cavity, let alone flow to the bottom wall of the installation cavity. In addition, the oil filter can be replaced after long-term use to maintain the oil smoke separation effect of the oil filter, effectively prevent oil pollution from polluting the installation cavity, and improve the convenience of user cleaning. The utility model patent of CN217090424 U has the following problems: 1. The bottom shell 1 is an integrally formed shell, and a deep installation cavity 11 is formed in the bottom shell 1. The heat insulation plate 4, the heating component 3 and the baking tray 2, the oil filter 5, the fan 6, and the oil collection box 8 all need to be arranged in the installation cavity 11. In this way, when installing, since the bottom shell 1 is integral, it is not convenient to assemble these accessories into the furnace body, which affects the assembly efficiency and further affects the production efficiency of the product. 2. Since the channel formed between the oil filter 5 and the heat insulation plate 4 is a straight channel, when frying and grilling, the oil smoke will be quickly sucked into the bottom shell 1 by the fan 6, and the oil smoke stays on the oil filter 5 for a relatively short time, which affects the adsorption effect of the oil filter 5. As the use time increases, the oil stains accumulate and flow along the inner wall of the shell to the bottom wall of the shell, which makes it more troublesome to clean. 3. The upper cover is directly covered on the furnace body. The cover needs to be removed when grilling, and the cover needs to be covered when grilling is finished. The operation is very inconvenient and can easily cause damage to the cover. Summary of the invention

A front strip slot 92 and a rear strip slot 93 are provided at the bottom of the middle support seat 9 for the front vertical clamping plate 82 and the rear vertical clamping plate 83 to be inserted respectively; a notch 901 for placing the electric control box 52 is provided on the top front side of the middle support seat annular outer wall 90, and a protruding sleeve 94 communicating with the notch 901 is provided on the bottom front side of the middle support seat 9, and the lower end of the protruding sleeve 93 is inserted into the annular clamping notch 841 of the positioning sleeve 84.

[0020] When the product is produced and assembled, the fan 3, the oil receiving pan 7, and the oil filter assembly 6 are installed on the base 8, and then the middle support seat 9 is covered on the base 8, and the annular plug-in piece 81 is inserted into the annular clamping groove 91 so that the middle support seat 9 and the base 8 are axially fixed during assembly. When the annular plug-in piece 81 of the base 8 is inserted upward into the annular clamping groove 91 of the middle support seat 9, the protruding sleeve 94 of the middle support seat 9 is inserted downward into the positioning sleeve 84 of the base 8, and the front vertical clamping plate 82 and the rear vertical clamping plate 83 of the base 8 are respectively inserted upward into the front strip slot 92 and the rear strip slot 93 of the middle support seat 9, so that the base 8 and the middle support seat 9 can achieve multiple locking and rapid assembly, and then the heat insulation plate 4, the electric control heating plate 5, the baking plate 501 or the boiling plate 502 and the oven cover 2 are installed on the middle support seat 9; the prior art that the bottom shell is integrated is abandoned, the assembly efficiency is improved, the structural rationality of the product is greatly improved, and the production efficiency of the product is increased by more than 3 times. Furthermore, when the product needs to be cleaned, it can be quickly disassembled and assembled to be thoroughly cleaned, thus avoiding the problems of limited space for disassembling accessories of the overall shell and incomplete cleaning of the inside of the shell in the prior art.

[0021] In the prior art CN217090424U, the oil filter assembly is directly and rigidly inserted into the housing. In CN217090424U, the oil filter assembly is directly and rigidly inserted into the housing. Since the space next to the motor is very narrow, it is often very difficult to insert the oil filter assembly. It takes a long time to align and force the oil filter assembly to install it into the housing. Even if it is installed into the housing, the oil filter assembly is often bent, which is not only inconvenient to assemble but also affects the oil filtering effect. The present invention overcomes these technical defects, see Figure 8, a plurality of blocks 85 are provided on the base 8, staggered inwardly from the upper slot 95. When the two ends of the oil filter net assembly 6 are respectively clamped in the upper slot 95 and the blocks 85, the oil filter net assembly 6 is tilted and placed between the base 8 and the middle support seat 9. A fume buffer channel 10 with a wide top and a narrow bottom is formed between the oil filter net assembly 6 and the side wall of the heat insulation plate 4. The fume buffer channel 10 is communicated with the air inlet 41. When installing the oil filter net assembly 6, the lower end of the oil filter net assembly 6 is first clamped on the block 85 of the base 8, and then the middle support seat 9 is covered, so that the upper end of the oil filter net assembly 6 is clamped in the upper slot 95 of the middle support seat 9. Not only can the oil filter net assembly 6 be quickly installed between the base 8 and the middle support seat 9, but the oil filter net assembly 6 will not be bent, thereby ensuring the oil filtering effect of the oil filter net assembly 6. Furthermore, since a fume buffer channel 10 which is wide at the top and narrow at the bottom is formed between the oil filter mesh assembly 6 and the side wall of the insulation plate 4, when the fume is sucked in by ventilation, the pressure of the fume entering from the air inlet 41 will gradually increase when passing through the fume buffer channel 10, thereby slowing down the downward speed of the fume, thereby increasing the contact time between the fume and the oil filter mesh assembly 6 and improving the oil absorption effect.

[0022] See also Figure 1-4 , Figure 13-21In order to improve the use efficiency of the oven cover 2, the oven cover 2 is detachably and rotatably mounted on the annular outer wall 90 of the middle support seat 9.

[0023] When the oven cover 2 needs to be mounted on the middle support seat 9, the oven cover 2 is placed vertically to form a vertical angle with the middle support seat 9, and then the two transverse flat shafts 25 of the oven cover 2 are aligned with the vertical opening 964 of the mounting seat 96 on the middle support seat 9 and inserted into the arc-shaped transverse groove 963, and then the oven cover 2 is rotated downward to the horizontal direction relative to the middle support seat 9, so that the oven cover 2 is quickly mounted on the middle support seat 9. Since the width of the transverse flat shaft 25 is greater than the width of the vertical opening 964, the oven cover 2 can be rotated relative to the middle support seat 9. When the oven cover 2 needs to be removed, the oven cover 2 is rotated to form an angle of 90 degrees with the middle support seat 9. After the oven cover 2 is rotated 90 degrees, the transverse flat shaft 25 is also rotated 90 degrees, and the height direction of the transverse flat shaft 25 is turned to the horizontal direction. Since the height of the transverse flat shaft 25 is smaller than the width of the vertical opening 904, the vertical opening 964 no longer restricts the transverse flat shaft 25, and the oven cover 2 can be pulled upwards to be quickly separated from the middle support seat 9.

[0024] During the rotation of the oven cover 2 relative to the middle support seat 9, the arcuate transverse groove 963 of the vertical support seat 961 and the transverse flat shaft 25 of the oven cover 2 are the first movable connection support points, and the arcuate clamping surface 965 of the vertical baffle plate 962 and the arcuate rotating surface 24 of the oven cover 2 are the second movable connection support points. Moreover, since the arcuate clamping surface 965 of the vertical baffle plate 962 and the arcuate transverse groove 963 of the vertical support seat 961 are staggered, the transverse flat shaft 25 and the arcuate rotating surface 24 are separated by a distance, thus realizing a stepped double-point clamping of the oven cover 2 during the rotation process, thereby ensuring the stability of the rotation of the oven cover 2.

[0025] In the present invention, whether the grilling is performed by placing a grilling pan 501 with an oil leaking hole on the heating tube 51, or by placing a cooking pan 502 with a closed bottom on the heating tube 51 for cooking or frying, the grill cover 2 should not be removed. When the grilling pan 501 is used for grilling, the grill cover 2 is rotated and opened, and the grill cover 2 is positioned on the middle support seat 9 in an open manner, and the oil smoke generated by the grilling food is circulated and filtered by the suction of the fan 3, and the oil smoke enters the middle support seat 9 from the air inlet 41, and the oil smoke forms an oil smoke buffer channel 10 with a wide top and a narrow bottom between the oil filter net assembly 6 and the side wall of the heat insulation plate 4, so that when the oil smoke is sucked, the oil smoke entering from the air inlet 41 will gradually increase in pressure when passing through the oil smoke buffer channel 10, slowing down the downward speed of the oil smoke, so that the contact time between the oil smoke and the oil filter net assembly 6 is increased, and the oil smoke is absorbed for a long time, and then the purified gas is continuously circulated from the air outlet 42.

[0026] When cooking or frying food with the cooking plate 502, the oven cover 2 can be closed or opened. When the oven cover 2 is closed, since cooking or frying is less fumes than grilling, the fumes generated by the food are mixed with the fresh air from the air intake opening 26, diluting the concentration of the fumes. Then the mixed gas enters the air inlet 41 together. The mixed gas forms a fumes buffer channel 10 with a wide top and a narrow bottom between the oil filter assembly 6 and the side wall of the heat insulation plate 4. The pressure gradually increases, slowing down the downward speed of the mixed gas, absorbing the fumes for a long time, and then the purified gas is output from the air outlet 42 and the air outlet 27.

[0027] In order to facilitate checking the status of food during the preparation process, a transparent glass plate 210 is provided on the oven cover 2, and a mounting hole 211 is provided on the rotating cover body 21 between the air supply inlet opening 26 and the air outlet hole 27, and an annular mounting step 212 is provided in the mounting hole 211, and the transparent glass plate 210 is fixed in the annular mounting step 212, and a sealing ring 213 is provided at the contact point between the transparent glass plate 210 and the mounting hole, and the handle 29 is fixed on the surface of the transparent glass plate 210.

[0028] In order to allow the movable end of the oven cover 2 to be gently covered on the middle support seat 9 and avoid damage to the oven cover 2, at least two protruding buffer seats 214 are provided at the bottom of the rotating cover body 21 located at one end of the handle 29, and an embedding groove 215 is provided in the buffer seat 214. The embedding groove 215 opens downward, and a bayonet 216 communicating with the embedding groove 215 is provided on the side wall of the embedding groove 215. A conical elastic block 217 with a thick upper part and a thin lower part is installed in the embedding groove 215, and a clamping head 218 that can be inserted into the bayonet 216 to fix the conical elastic block 217 in the embedding groove 215 is provided on the side wall of the conical elastic block 217. The height of the conical elastic block 217 is greater than the depth of the embedding groove 215, and the bottom of the conical elastic block 217 is stuck on the annular outer wall 90 of the middle support seat when the oven cover 2 is covered on the middle support seat 9. When the oven cover 2 is pressed against the middle support seat 9, the conical elastic block 217 will undergo elastic deformation, and the compressed conical elastic block 217 will become shorter and thicker, and be more tightly stuck in the embedding groove 215, so that the oven cover 2 is buckled on the middle support seat 9 more tightly and softly.
