Description

Heating tube lifting adjusting structure and oven Technical Field The utility model relates to the field of household appliances, in particular to a heating tube lifting adjusting structure and an oven. Background The heating mechanism of most of the existing ovens is usually set to be a fixed structure, and cannot move to change the distance between the heating mechanism and the bearing frame, so that the heating distance of food cannot be adaptively adjusted according to the characteristics of the height, thickness and the like of the food, the baking effect of partial food is poor, and the baking speed cannot be further improved due to the fixation of the heating distance. The Chinese patent publication No. CN109984627A discloses an oven, an upper moving heating pipe and a lower moving heating pipe are arranged in an oven liner, the upper moving heating pipe is connected with a first lifting driving mechanism, the lower moving heating pipe is connected with a second lifting driving mechanism, and the upper moving heating pipe and the lower moving heating pipe are driven to move up and down, so that the distance between the upper moving heating pipe and the lower moving heating pipe can be freely changed according to the requirement, and the baking effect of each layer of food can be ensured to be consistent when the multilayer food is baked. However, the rack, the guide rail, the sliding block and other structures of the lifting driving mechanism are exposed in the inner container, oil and grease can form oil vapor in the use process of the oven, the oil vapor is easy to adhere to the guide rail and other structures, and oil dirt which is difficult to clean can be formed because the structural gaps or fit gaps of the structures are smaller, the rack is influenced to engage with and drive or the sliding block is prevented from sliding, so that the cleaning of a user is inconvenient, and the durability is poor. Disclosure of utility model Aiming at the defects in the prior art, one of the purposes of the utility model is to provide a heating tube lifting adjusting structure, a T-shaped transmission piece is adopted to drive the heating tube to move in the height direction, and a sliding mechanism and a driving mechanism can be arranged independently of a heating space, so that the influence of oil dirt is reduced.

The T-shaped transmission part is used for being in transmission connection with the connecting piece, the connecting piece is used for fixing the heating tube, the lower part of the T-shaped transmission part is used for being connected with the driving mechanism, driving force of the driving mechanism is transmitted to the connecting piece, and therefore the connecting piece is driven to drive the heating tube to move. The sliding mechanism is located on the side face of the T-shaped transmission piece, and can achieve guiding effect through connecting the T-shaped transmission piece, so that position adjustment of the T-shaped transmission piece is limited in the height direction. The T-shaped transmission part separates the heating tube from the positions of the driving mechanism and the sliding mechanism through the vertical and horizontal structures, so that the driving mechanism and the sliding mechanism can be far away from the influence of oil vapor during operation, the blocking oil scale generated by accumulating oil stains in a structural gap or a fit gap of the driving mechanism and the sliding mechanism is reduced, and the smooth operation of the heating tube lifting adjusting structure is effectively ensured. In the preferred technical scheme of the utility model, the driving mechanism comprises a motor and a gear, the gear is fixed at the shaft end of the motor, the T-shaped transmission piece comprises a vertical structure and a horizontal structure, a sawtooth part is arranged on one side of the vertical structure, and the sawtooth part is meshed with the gear. The driving mechanism is driven by a motor and a gear, and the gear is driven to rotate by the motor. The sawtooth part is a sawtooth structure formed on the T-shaped transmission piece, and the sawtooth part is meshed and matched with the gear, so that the rotary drive of the motor can be converted into the movement of the T-shaped transmission piece. In addition, the sawtooth part is arranged on the side edge of the T-shaped transmission part, so that the space occu
