Description

Technical Field

[0001] The invention relates to a kitchen appliance, in particular to a steaming and baking all-in-one machine capable of steaming and baking. Background Art

[0002] There are more and more steam-bake machines on the market. They are generally embedded machines with upper and lower double inner pots with steaming function. Each inner pot is equipped with an independent door assembly. The upper inner pot can realize the steam function, and the lower inner pot can realize the functions of baking, steaming and steaming and baking at the same time. The upper and lower inner pots use separate door assemblies, and the operation display screen (also the upper inner pot door handle) is located on the outer glass of the upper door assembly for easy operation.

[0003] Due to limited space, one air outlet is usually used and placed above the upper inner tank. When the lower inner tank uses the steaming function, the door assembly is opened, and a large amount of steam in the lower inner tank escapes. Since there is no external force, most of the steam rises upward during the escape process, causing a large amount of steam to condense and produce water droplets on the upper inner tank door assembly and the operation display screen, affecting the user's operating experience.

[0004] When the lower inner pot is in steam-bake mode, due to a certain gap in the hot air blower shaft, the steam escapes along the shaft to the back of the all-in-one machine, causing air leakage. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a steam-bake combination machine in which steam does not escape to the back of the machine body in response to the above-mentioned technical status quo.

[0006] Another technical problem to be solved by the present invention is to provide a steam-bake combination machine capable of reducing the upward rise of steam when a door assembly is opened in response to the above-mentioned technical status quo.

The fan assembly 5 is arranged on the rear cover 26, and the electric heating pipe 24 is arranged on the rear plate 23. The first fan 51 is located in the gap between the baffle and the rear plate 23, and the second fan 52 is located on the rear end surface of the rear cover 26. A sealing ring 27 is provided on the through hole through which the output shaft of the power supply machine 54 of the rear cover 26 passes.

[0053] Combination Fig.10 and Fig.11 As shown, the outer end surface of the first door assembly 11 is provided with an operation display screen 12, the outer end surface of the first door assembly 11 is a vertical surface, and the lower end of the operation display screen 12 is tilted outward so that the operation display screen 12 forms an acute angle with the outer end surface of the first door assembly 11. The outer end surface of the first door assembly 11 is provided with a display screen bracket 123, the display screen bracket 123 has an inclined mounting end surface, and the operation display screen 12 is arranged on the mounting end surface of the display screen bracket 123. In this way, even if a small amount of steam rises upward, it needs to bypass the tilted part below, and it is not easy to directly reach the end surface of the operation display screen to form condensed water.

[0054] Specifically, a glass cover 121 is provided on the outside of the operation display screen 12 via a glass bracket 122 , and a display screen bracket 123 is provided with an outer end surface of the first door assembly 11 via a fixing bracket 124 and is sealed with a sealing ring 125 .

[0057] Combination Figure 4 and Figure 5As shown, the exhaust duct 3 is arranged above the first inner liner 1, and the exhaust duct 3 is assembled by an upper air guide cover 3a and a lower air guide cover 3b, and an air guide channel is formed. The exhaust duct 3 specifically includes a fan mounting section 33, an air collecting section 31, and a flared section 32 connected to the air collecting section 31, the flared section 32 is narrow inside and wide outside, a rotatable exhaust fan 34 is arranged in the fan mounting section 33, and the air collecting section 31 has a first air inlet end 35 and a second air inlet end 36, the first air inlet end 35 is connected to the first inner liner 1 through a first exhaust pipe 61, and the second air inlet end 36 is connected to the second inner liner 2 through a second exhaust pipe 62.

In this embodiment, the air guide channel is divided into two air outlet channels by a partition plate 37, one for the steam in the first inner pot 1 and the other for the steam in the second inner pot 2.

[0058] When the second inner pot 2 enters the baking function mode, the motor 54 rotates in the counterclockwise direction at a medium speed; at this time, the first fan allows the air in the second inner pot to enter from the ventilation hole of the baffle and be discharged from the side of the baffle. The second fan can effectively prevent the hot air in the second inner pot from escaping from the gap of the motor output shaft to the back of the machine body.
