Self-adaptive hot air structure and cooking device with same

Abstract

The invention relates to a self-adaptive hot air structure, which comprises a liner; a hot air baffle is arranged on the rear side of the inner cavity of the liner; a hot air chamber is defined by thehot air baffle and a back plate of the liner; an air heater is arranged in the hot air chamber; a back heating pipe is arranged at the periphery of the air heater; an exhaust port and a ventilation opening are formed in the hot air baffle; the exhaust port is formed in the outer side of the horizontal projection of fan blades of the air heater on the hot air baffle; a blocking piece is embedded in the ventilation opening; the blocking piece can rotate in the ventilation opening with the first axis transversely penetrating through the ventilation opening as the center; the air pressures of theportions, on the two sides of the first axis, of the ventilation opening are different; and when the blocking piece is flush with the plane where the ventilation opening is located, the ventilation opening can be blocked. The self-adaptive hot air structure has a good adjusting effect on the back temperature field of the liner and is low in noise, and when the air heater does not work, the blocking piece can shield the ventilation opening, so that the air heater, the back heating pipe and other components in the hot air chamber are shielded, the whole appearance of the liner is tidier and more attractive, and meanwhile daily cleaning of a user is facilitated.

Description

technical field [0001] The invention relates to the field of cooking devices, in particular to an adaptive hot air structure and a cooking device with the structure. Background technique [0002] In order to make the temperature field inside the inner tank more uniform in existing cooking devices such as ovens, steamers or all-in-one steamers, a hot air circulation structure is generally arranged on the back of the inner tank. The hot air circulation structure generally includes a hot air baffle, a hot air blower and a back heating pipe. The middle part of the hot air baffle is provided with an air inlet, and the outer periphery of the hot air baffle is respectively provided with an air outlet. Side, it and the back plate of liner encircle the hot air chamber, above-mentioned hot air blower is arranged in this hot air chamber and is opposite to the front and rear of the air inlet of hot air baffle, and the back heating pipe is surrounded by the periphery of this hot air blow...

AI Technical Summary

Problems solved by technology

However, there are still the following problems in this method: (1) the forward and reverse air blower is used, and since other configurations remain unchanged, the change of the temperature field of the hot air on the back is not obvious; When the fan
