Description

TECHNICAL FIELD

[0001] The utility model relates to food processing device, especially an air fryer. BACKGROUND

[0002] The working principle of the air fryer is "high-speed air circulation technology", which generates hot air by heating the heat pipe in the machine, then blows the hot air into the pot by the fan to heat the food, makes the hot air circulate in the closed space, uses the oil of the food itself to fry the food, so that the food is dehydrated, the surface becomes golden and crisp, and the effect of frying is achieved. In order to reduce the loss of heat energy, the space in the cooking cavity needs to be relatively sealed, which can also reduce the loss of water too fast and affect the taste of the food.

[0003] The existing air fryer has two common models. One is the upper cover opening type, similar to the electric pressure cooker, the machine head is hinged or detachable from the machine body, the machine body is provided with an outer pot and an inner pot, the inner pot is used to hold food materials, the inner pot is taken out or put into the top of the outer pot after the machine head is opened, the sealing relationship between the machine head and the machine body is relatively easy to realize, so the heat loss is less. The second is the drawer type, which generally includes a machine body and a pot assembly, the machine body is provided with a containing cavity, one side of the machine body is provided with an opening communicating with the containing cavity, the pot assembly includes a pot and a heat insulation side plate, the pot is loaded into or removed from the containing cavity through the opening, and the heat insulation side plate is fixed to one side of the pot and cooperates to close the opening. Due to the gap between the heat insulation side plate and the machine body, it is difficult to achieve good sealing of the cooking cavity, so the heat loss is more, the water loss is also faster, the food materials are easy to dry and hard, and the taste is not good. How to realize good sealing of the cooking cavity is a problem to be solved for the drawer type air fryer.

[0004] The prior art CN212996084U discloses a drawer type air fryer, which aims to overcome the problem of gap between the pot opening edge of the oil receiving barrel assembly and the heat insulation plate of the air fryer cover. The specific structure includes a main machine and an oil receiving barrel for placing food and collecting oil. The main machine is provided with a cavity structure, and the oil receiving barrel is installed in the cavity structure and can be removed from the side of the main machine. The main machine is provided with an air fryer cover that covers the oil receiving barrel. The air fryer cover is provided with a heat insulation plate, which is located above the opening structure of the oil receiving barrel. The air fryer cover is also provided with a sealing assembly for sealing the heat insulation plate and the opening structure. Specifically, the sealing assembly is an elastic sealing ring structure. The sealing assembly seals the heat insulation plate and the opening structure of the oil receiving barrel, preventing hot air from the head heating device from leaking out of the gap between the heat insulation plate and the opening structure of the oil receiving barrel during baking or steaming. This can cause the temperature in the cavity structure to rise too high or cause condensation in the inner cavity, which can seriously affect the surface temperature rise of the shell and the cooking effect. For example, the prior art CN213309197U also discloses a drawer type air fryer, which is a ring-shaped sealing pipe between the pot body and the heating cavity. The sealing pipe is provided with a pipe cavity connected with the outside space. After installation, the pipe cavity is deformed and sealed by the sealing clamp, preventing heat leakage in the cooking cavity, improving heat utilization efficiency, and ensuring safety and preventing burns.

[0005] In the above prior art, the sealing components are clamped between the pot body and the components above it (the heat insulation plate in CN212996084U or the air deflector in CN213309197U), and directly face the cooking cavity and the circulating hot air, which can easily attach oil stains to the sealing components, causing cleaning difficulties for users. In addition, most users use the drawer type air fryer, and since the upper edge of the pot body is in a visible position and the bottom surface of the pot body is not visible, users generally align the upper edge of the pot body with the upper edge of the receiving cavity and push it in. Therefore, the upper edge of the pot body can easily hit the sealing component and contact and press the sealing component during the pushing in or out process. The sealing component can also generate frictional resistance to the pot body, which can hinder the user's operation, causing an unpleasant user experience. In addition, long-term use can cause damage to the sealing component, affecting its sealing performance. Practical new type

Body 100 forms hot air chamber at the top of containing cavity 101, and hot air assembly is arranged in hot air chamber, and hot air assembly generally includes fan and heating tube, and hot air assembly transports hot air to the inner chamber of pot body 21 to heat food material, the utility model passes through the combination of first sealing pad 31 and second sealing pad to ensure the sealing property of the inner chamber of pot body 21 and hot air chamber, to reduce heat energy loss, ensure heating efficiency and effect, simultaneously, the sealing component--first sealing pad 31 is clamped between flanging 211 and support surface 103, namely, the first sealing pad 31 is located below flanging 211, and the first sealing pad 31 will not directly face cooking cavity, and is shielded through flanging 211, is favorable for reducing the oil dirt attachment on the first sealing pad 31, reduces the cleaning difficulty and workload of user, simultaneously, considering the operation habit of user, when pot body subassembly 200 is pushed in or removed, flanging 211 is upwardly abutted with body 100, will form the gap between the first sealing pad 31 below, basically avoids the possibility of impacting the first sealing pad 31 when user operates pot body subassembly 200, is favorable for guaranteeing the service life of first sealing pad 31, and the friction resistance of flanging 211 and body 100 contact is obviously less than the friction resistance of flanging 211 and first sealing pad 31 contact, greatly reduces the hindrance of sealing component to the movement of pot body subassembly 200, when user operates pot body subassembly 200, is more smooth, is favorable for guaranteeing that user obtains good use experience. For the convenience of user operation, the outside of heat insulation side plate 22 generally will be provided with handle 23.

[0041] In one embodiment, the first sealing gasket 31 can be installed on the support surface 103, and in order to improve the positioning reliability of the first sealing gasket 31, a first positioning groove 104 for fixing the first sealing gasket 31 can be arranged on the support surface 103, so that even if the flange 211 rubs against the first sealing gasket 31, the first sealing gasket 31 is not easy to be separated from the support surface 103, and when the user needs to clean the first sealing gasket 31, the first sealing gasket 31 can be conveniently removed from the support surface 103. In addition, the first sealing gasket 31 can also be fixed to the pot body 21, and the first sealing gasket 31 can move with the pot body 21, so that the first sealing gasket 31 can be cleaned when the pot body 21 is cleaned, which is more convenient. The fixing method of the first sealing gasket 31 and the pot body 21 can adopt common methods such as embedding and clamping, which will not be described here.

[0042] In order to guide the user to conveniently and quickly move the pot body assembly 200 and accurately and reliably position the pot body assembly 200, the machine body 100 can be designed to have a sliding groove 105 extending rearward from the opening 102 on the side surface of the machine body 100 located on both sides of the opening 102, and a communication groove 106 connected to the sliding groove 105 on the rear side surface of the accommodating cavity 101. The lower side surface of the sliding groove 105 and the lower side surface of the communication groove 106 form the support surface 103, the flange 211 on both sides of the pot body 21 is inserted into the sliding groove 105, and the flange 211 on the rear side of the pot body 21 is inserted into the communication groove 106. The width dimension of the sliding groove 105 in the longitudinal direction can be greater than the sum of the thickness of the first sealing gasket 31 and the flange 211, so as to ensure that there is a certain gap between the flange 211 and the first sealing gasket 31 when the flange 211 moves in the sliding groove 105, thereby reducing the probability of contact between the flange 211 and the first sealing gasket 31.

[0043] In order to ensure the sealing effect between the machine body 100 and the heat insulation side plate 22 at the opening 102, in one embodiment, the second sealing gasket includes an upper sealing gasket 321 located between the top surface of the heat insulation side plate 22 and the machine body 100, and the upper sealing gasket 321 extends along the top surface of the heat insulation side plate 22 from one side of the opening 102 to the other side of the opening 102.

[0044] The upper sealing gasket 321 can be fixed on the machine body 100, and in order to improve the fixing reliability of the upper sealing gasket 321, a third positioning groove 107 for positioning the upper sealing gasket 321 can be arranged on the machine body 100 on the upper side of the opening 102; or the upper sealing gasket 321 can also be fixed to the top surface of the heat insulation side plate 22.

[0045] When the user operates the pot assembly 200, the upper edge of the pot 21 is generally pushed into the pot assembly 200 after being aligned with the upper edge of the accommodating cavity 101, and thus can collide with the upper sealing gasket 321.

When the pot 21 collides with the upper sealing gasket 321, the two ends of the upper sealing gasket 321 can attract a certain force in the moving direction of the pot 21, thereby effectively preventing the upper sealing gasket 321 from being separated from the machine body 100. At the same time, since the upper sealing gasket 321 is arranged only on the upper side of the opening 102, the contact area with the pot 21 is small, and the friction generated is relatively small, so that the user does not feel obvious resistance when operating the pot assembly 200.

[0046] In one embodiment, the projections of the two ends of the upper sealing gasket 321 on the horizontal plane can overlap the two ends of the first sealing gasket 31. The projections of the upper sealing gasket 321 and the first sealing gasket 31 on the horizontal plane can form a closed annular structure, which is beneficial to ensure the sealing effect and reduce heat loss.

[0047] On the basis of arranging the upper sealing gasket 321, the sealing effect between the machine body 100 and the heat-insulating side plate 22 at the opening 102 can be further improved. Specifically, the heat-insulating side plate 22 has protruding portions 221 protruding relative to the pot 21 on the two sides thereof, and the second sealing gasket further includes side sealing gaskets 322 between the inner side surfaces of the protruding portions 221 and the side surfaces of the machine body 100 on the two sides of the opening 102. The side sealing gaskets 322 extend longitudinally from the top ends of the protruding portions 221 to the bottom ends of the protruding portions 221.

[0048] In one embodiment, the top ends of the side sealing gaskets 322 can be connected to the two ends of the first sealing gasket 31 respectively to form an integral part, thereby reducing the number of sealing components and facilitating production and disassembly. In another embodiment, the top ends of the side sealing gaskets 322 can also be connected to the two ends of the upper sealing gasket 321 respectively, which can also reduce the number of sealing components.

[0049] The side sealing gaskets 322 can be fixed to the machine body 100, and to increase the fixation reliability of the side sealing gaskets 322, the machine body 100 can be provided with second positioning grooves 108 on the side surfaces thereof on the two sides of the opening 102 for fixing the side sealing gaskets 322. Alternatively, the side sealing gaskets 322 can also be fixed to the protruding portions 221, for example, the protruding portions 221 can be provided with positioning grooves for embedding the side sealing gaskets 322.
