Detailed Description

The essential features of the utility model are further described in connection with the accompanying drawings and the detailed description.

Embodiment one:

the present embodiment provides an air fryer.

The air fryer shown in fig. 1 is composed of a shell 1 with a pot body 2 and a hot air component, wherein a frying basket 21 is arranged in the pot body 2, a through hole 211 is formed in the bottom wall of the frying basket 21, hot air generated by the hot air component is input into the pot body 2 to cook food materials on the frying basket 21, a collector 3 is arranged on the through hole 211 in the middle of the bottom wall of the frying basket 21, a vertically through collecting channel 31 is arranged in the collector 3, and the area of the lower port of the collecting channel 31 is larger than that of the corresponding through hole 211.

In this embodiment, a hot air cavity communicated with the pot body is provided in the housing 1, and a hot air component is provided in the hot air cavity, and the hot air component is electrified to generate hot air for cooking food materials, so that the food materials in the pot body 2 are effectively cooked. The hot air assembly comprises a fan and a heating element, the heating element is positioned at the periphery of the fan, the rotating fan extracts air in the cooking cavity and forms air flow flowing through the heating element, the air flow absorbs heat and forms hot air flowing back to the pot body 2, and the hot air can be contacted with food materials after flowing into the pot body 2 and realize heat transfer, so that the food materials are gradually cooked from outside to inside. The hot air component extracts air in the cooking cavity and forms hot air which flows back to the pot body 2 after being heated, so that the air circularly flows between the hot air cavity and the pot body 2.

In this embodiment, a frying basket 21 is disposed in the pan body 2, the frying basket 21 is suspended in the pan body 2, so that a channel for flowing hot air in a direction is formed in a region below the frying basket 21 at the bottom of the pan body 2, and a through hole 211 is formed in the bottom wall of the frying basket 21. When the frying basket 21 is used, the frying basket 21 is placed in the pot body 2, food materials are placed in the frying basket 21, the hot air component is electrified to run and generate hot air, the hot air can downwards flow to the bottom of the pot body 2 along the inner side wall of the pot body 2 and is converged inwards along the bottom wall of the pot body 2, and when the hot air flows inwards along the bottom wall of the pot body 2, the hot air can be split through the through holes 211 along the way, so that the bottom wall of the food materials is heated. Because the flow of the hot air can be reduced due to the along-way diversion in the middle flowing process, and the drainage efficiency of each through hole 211 is the same, the flow of the hot air flowing through the through hole 211 positioned in the middle of the bottom wall of the frying basket 21 can be smaller than the flow of the hot air flowing through the through hole 211 positioned in the side part of the bottom wall of the frying basket 21, and the periphery of the bottom wall of the food material can be cooked before the middle part, so that the food material can not be uniformly cooked, and the using experience is affected. For this reason, set up collector 3 on the through-hole 211 that is located the bottom wall middle part of frying basket 21, adjust the drainage efficiency of each through-hole 211 through collector 3, promote hot air flow through the drainage efficiency that the increase is located the bottom wall middle part through-hole 211 of frying basket 21, and then promote the culinary art efficiency at food material bottom wall middle part, promote and use experience.

In this embodiment, a vertically penetrating collecting channel 31 is disposed in the collector 3, and the area of the lower port of the collecting channel 31 is larger than the area of the corresponding through hole 211. Drainage efficiency is promoted through increasing collector 3's lower port area, and then overcomes the ripe inconsistent problem of system that appears because of hot-blast flow is too little, promotes the use experience.

In addition, because the cross section size of the middle section of the collecting channel is smaller than that of the lower port, the venturi effect can be generated when the hot air flows through the collecting channel 31, the flow velocity of the hot air flowing through the collecting channel 31 is effectively improved, and the heat is further ensured to be rapidly conveyed.

In this embodiment, the number of through holes 211 is plural, and corresponding collectors 3 are installed, different open angles are formed between opposite areas of the side walls of the lower port of the collector 3, and the open angle of the collector 3 gradually increases from outside to inside along with the position of the through hole at the bottom wall. Under the condition that the height of the lower port of the collector 3 is constant, the cross-sectional area ratio between the lower port and the corresponding through hole 211 is adjusted by setting different opening angles at different through hole positions, so that the drainage efficiency is adjusted. Specifically, the larger the opening angle is, the higher the drainage efficiency is, whereas the smaller the opening angle is, the lower the drainage efficiency is, when the horizontal flow is smaller in the hot air flow at the lower port of the collecting channel 31 in use, the drainage efficiency is improved by increasing the opening angle, and further, the hot air flow in the collecting channel 31 is ensured to meet the cooking requirement.

In this embodiment, the bottom wall includes a peripheral area, a joining area and a middle area, which are sequentially disposed from outside to inside, and since the hot air at the bottom of the pan body 2 has gradually reduced flow rates of the hot air in the peripheral area, the joining area and the middle area due to the split flow along the way when flowing in the middle, in order to ensure that the through holes 211 disposed in the peripheral area, the joining area and the middle area obtain the same flow rate of the hot air, collectors 3 having different open angles may be disposed in the joining area and the middle area, so as to ensure that the through holes 211 disposed in the joining area and the middle area obtain the same flow rate of the hot air as that in the through holes 211 of the peripheral area, thereby ensuring that the bottom of the food is uniformly cooked.

During installation, the collector 3 is inserted into the through hole 211 through self deformation, and then is sleeved on the periphery of the through hole 211 through the caulking groove 32 by utilizing self deformation recovery, so that the collector 3 is vertically positioned, the collector 3 is prevented from being separated from the through hole 211, sealing connection between the collector 3 and the through hole 211 is ensured, and upward flow of hot air through the collecting channel 31 is ensured.

In this embodiment, the collector 3 is a silica gel piece, which has good deformation recovery performance, is convenient to install, has good sanitary safety performance, prevents toxic and harmful substances from being emitted due to heating, and improves use safety.

In this embodiment, the contour of the inner sidewall of the caulking groove 32 matches with the contour of the periphery of the through hole 211, so that the periphery of the through hole 211 is completely embedded in the caulking groove 32. After the mounting in place, the top wall of the caulking groove 32 is matched and attached with the top wall of the periphery of the through hole 211, the inner side wall of the caulking groove 32 is attached with the side wall of the through hole 211, and the bottom wall of the caulking groove 32 is matched and attached with the bottom wall of the periphery of the through hole 211, so that the collector 3 is firmly connected to the through hole 211. After the collector 3 is installed, the bottom surface of the collector 3 is arranged at equal height, so that the wind resistance of hot air flowing horizontally at the bottom of the pot body 2 is effectively reduced, and the hot air can smoothly flow to the middle.
