Detailed Description

The structure of the cookware with oil smoke processing function applying the technical scheme of the invention is further explained with reference to the attached drawings.

The invention provides a pot with an oil smoke treatment function, as shown in fig. 1 and fig. 2, the pot comprises a pot body component and an upper cover component arranged above the pot body component, the pot body component comprises a base outer shell 41 and an inner pot 42 arranged in the base outer shell 41, the inner pot 42 is provided with a cooking inner containing cavity 421, and the inner pot 42 is used for containing cooking food.

The upper cover component is provided with a hot air circulation component 2. The first implementation structure of the hot air circulation component 2 may be that the hot air circulation component 2 includes a motor 21, a top heater 23 and fan blades 22 driven by the motor 21, an upper cover outer shell 31 is further disposed on the upper cover component, a reflective cover 32 facing the cooking inner cavity 421 is disposed below the upper cover outer shell 31, and actually, the inner pot 42 and the reflective cover 32 are combined up and down to form a closed cooking inner cavity 421. The motor 21 is disposed above the reflective cover 32, the fan blades 22 and the top heater 23 are disposed below the reflective cover 32, and a motor shaft 211 of the motor passes through the reflective cover 32 and extends to a space below the reflective cover 32, and the fan blades 22 are installed. The top heater 23 can raise the temperature of the air around the heater 23 by heating to form high-temperature hot air, and the fan blades 22 rotate under the action of the motor 21 and drive the hot air to flow to the lower part of the reflector 32 along the inner surface of the reflector 32. When the upper cover assembly covers the pot body assembly, the reflecting cover 32 and the inner pot 42 are buckled with each other, the space in the reflecting cover 32 and the cooking inner containing cavity 421 of the inner pot 42 are communicated with each other to form a space capable of allowing hot air to circularly flow, and hot air formed by the hot air circulation assembly 2 flows to the cooking inner containing cavity 421 in the inner pot from the space in the reflecting cover 32, so that food is cooked. After the hot air flows through the food in the inner pot 42, part of heat in the hot air is used for heating the food to do work so as to reduce the temperature of the hot air, meanwhile, the rotation of the fan blades 22 enables the air pressure at the periphery of the radial outer edge of the fan blades 22 to be increased and the air pressure near the center of the fan blades 22 to be reduced, the hot air with the reduced temperature flows to the vicinity of the center of the fan blades 22 through the top heater 23 under the action of the air pressure difference formed by the fan blades 22, the air is heated again and then flows to the cooking inner containing cavity 421 through the driving of the fan blades 22, and therefore the hot air circulation assembly 2 enables the cooking inner containing cavity 421 to generate hot circulation air so as to continuously heat the food in the inner pot 42.

In another embodiment (not shown in the drawings), another implementation structure with the same function and effect of the hot air circulation component 2 may be that the hot air circulation component 2 may also be another hot air channel which is communicated with the cooking inner cavity 421 and can provide high-speed hot air to the cooking inner cavity 421, and the hot air channel may be disposed on a pot body component or the upper cover component of the pot, and the high-speed hot air provided by the hot air channel can rotate at high speed in the cooking inner cavity 421 to heat food, and of course, can pass through the hot air channel into the air channel cavity 511 to be mentioned later.

In one embodiment, when the filtering component in the air outlet duct exhausts badly due to the fact that the filtering component absorbs a lot of oil smoke particles after being used for a long time, the controller senses that the oil smoke concentration in the air outlet duct exceeds a preset threshold value, the cooker can be controlled to stop working, and further the cooker can also make a prompt signal to prompt a user to check the air outlet duct or replace the filtering component 53.

As shown in fig. 1 and 2, the fan blade 22 and the top heater 23 of the hot air circulation assembly 2 are disposed below the reflection cover 32, however, since the covering size of the reflection cover is large, it may affect that the hot air circulating from the hot air circulating assembly 2 is not intensively blown to the middle of the cooking cavity 421, resulting in long heating time or poor heating effect, in one embodiment, a wind scooper 8 is further arranged below the reflector 32, the upper part of the wind scooper 8 is provided with a cover upper opening 81, the edge of the upper opening 81 is connected to the inner side of the top of the reflection cover 32, the fan blade 22 and the top heater 23 are positioned in the air guiding cover 8, the reflector avoidance hole 321 is located at the outer side of the air guiding cover 8, and the air guiding cover 8 is used for guiding the hot circulating air to blow towards the central area of the cooking cavity 421. The air guiding cover 8 can separate the reflector avoiding hole 321 from the fan blade 22 and the top heater 23 which generate the thermal circulation air, the thermal circulation air is firstly blown to the central area of the cooking inner cavity 421 by the guiding of the air guiding cover 8, after the thermal circulation air flowing into the cooking inner cavity 421 heats the food in the inner pot 42, one part of the thermal circulation air flows back to the vicinity of the center of the fan blade 22 upwards and flows circularly, the other part of the thermal circulation air flows towards the reflector 32 upwards along the pot wall of the inner pot 42, and the thermal circulation air flowing towards the reflector 32 can drive part of the oil smoke to enter the air outlet channel from the reflector avoiding hole 321 and is filtered by the filter component 53 and then discharged to the outer space of the upper cover component, so that the heat utilization efficiency of the thermal circulation air is improved, and the loss of heat energy is reduced.
