Door assembly and cooking equipment provided with same

Abstract

The invention discloses a door assembly and cooking equipment provided with the door assembly, the door assembly comprises outer glass, middle glass, a door body, a choke plate and inner glass, the middle glass is arranged on the inner side of the outer glass, the door body is arranged between the middle glass and the inner glass, the choke plate is arranged on the door body, an annular groove distributed in the circumferential direction is formed in the rear side of the door body, and the inner glass is arranged in the annular groove. The choke plate is installed on the rear side of the door body, the peripheral portion of the choke plate extends into the opening portion of the annular groove to be matched with the annular groove to form a choke cavity, and the rear side of the door body is provided with a microwave sealing face surrounding the periphery of the choke cavity. The choke cavity of the door assembly of the cooking equipment forms a first microwave seal, and the microwave sealing surface of the door body is in sealing fit with the cavity front plate of the cooking cavity to form a second microwave seal, so that the reliability of the microwave seal of the door assembly is improved, and the use safety is improved. In addition, the door sealing ring is designed in the front plate of the cavity, so that the influence on the appearance and the easy-to-clean property of the door assembly is avoided, and meanwhile, the steam sealing is ensured.

Description

technical field [0001] The present invention relates to a cooking device, in particular to a door assembly and a cooking device installed with the door assembly. Background technique [0002] With the continuous improvement of people's quality of life, kitchen appliances are becoming more and more abundant, and microwave ovens, ovens, steamers, etc. have gradually become the necessary kitchen appliances for family life. These kitchen appliance products not only have a single function, but each product needs to occupy a certain kitchen space, and it is expensive to purchase separately. In order to effectively use the kitchen space, people have invented a steamer, oven and microwave oven. Since the steaming and baking micro-integrated machine needs to work in the microwave mode, the microwave leakage prevention structure of the door assembly is particularly important. The existing door assembly usually only uses the choke plate inside the door assembly to prevent microwave le...

AI Technical Summary

Problems solved by technology

Since the steaming and baking micro-integrated machine needs to work in microwave mode, the anti-microwave leakage structure of the door assembly is particularly important. The existing door assembly usually only prevents microwave leakage through the choke plate inside the door assembly, that is, only one Microwave sealed structure, the effect is not good

In addition, the door assembly of the existing steaming and baking micro-integrated machine also has the following defects: 1. The door assembly generally adopts a plastic door seal, which not only has an unattractive appearance, but also has defects such as deformation and cracking of the plastic easily in the long-term grilling mode. The plastic door seal is used. Generally, the interlock column of the top micro switch is also directly integrated with the plastic door seal. It is also made of plastic material. After a long period of opening and closing the door, there may be a risk of breaking the interlock column.

2. The door sealing ring is designed in the door assembly, which not only affects the appearance, but also is not easy to clean; 3. There are many internal parts in the door assembly, which makes it impossible to achieve up, down, left, and right ventilation, resulting in an increase in the temperature of the outer door glass; 4. When bonding the inner glass, when When the gap between the edge of the inner glass and the door body is large, the glue between the inner glass and the door body will leak directly, and the bonding effect will not be achieved. When the gap between the inner glass and the door body is small, it will be inserted into the gap After the glue is cured, it is easy to be higher than the upper surface of the door body, thus affecting the sealing between the door body and the front panel of the cavity; The phenomenon that the micro switch in the interlocking component of the door component cannot operate, and the safety of use needs to be improved
