However, these utility model concepts can be embodied in many different forms, and therefore should not be considered limited to the embodiments described herein.

[0030] It should be noted that the embodiments in the utility model and the features in the embodiments can be combined with each other without conflict. The direction terms in the application are based on the direction of the cooking device in the conventional placement state, and can also refer to the coordinate system in the attached Figure 1 The blue lines and marks in the attached Figure 2 , 6 in the application are size marks to avoid confusion with structure lines. The red arrows in the attached Figure 7 in the application represent the direction of air flow.

[0031] The utility model will be described in detail below with reference to the attached drawings and in combination with the embodiments.

[0032] In order to solve the problem of high surface temperature of the integrated door frame handle in the prior art, which can easily scald the user, the embodiments propose a door assembly, as shown in the attached Figures 1-7 , the door assembly 1 comprises a door frame 3, an anti-scald handle assembly 2, the anti-scald handle assembly 2 is connected with the door frame 3; an air isolation groove 5 is arranged between the anti-scald handle assembly 2 and the door frame 3, the air isolation groove 5 is communicated with the external environment, so that external air can enter the air isolation groove 5 to cool the anti-scald handle assembly 2.

[0033] ​Therefore, for the door assembly with the integrated door frame handle, by arranging the air isolation groove 5 between the anti-scald handle assembly 2 and the door frame 3, an air insulation layer can be formed between the anti-scald handle assembly 2 and the door frame 3 as external air enters the air isolation groove 5, which can block the heat transfer from the inside of the cooking device to the anti-scald handle assembly 2 to some extent, and on the other hand, the heat of the anti-scald handle assembly 2 can be effectively dissipated as the air flows in the air isolation groove 5. Under the joint action of the two aspects, the surface temperature of the anti-scald handle assembly 2 can be effectively reduced to avoid scalding the user when touching the handle, and the user experience can be improved.

[0034] The anti-scald handle assembly 2 is provided with an air inlet groove 23 and an air outlet groove 25, one end of the air inlet groove 23 is in communication with the external environment, the other end is in communication with the inlet of the air isolation groove 5, one end of the air outlet groove 25 is in communication with the outlet of the air isolation groove 5, and the other end is in communication with the external environment; therefore, by arranging the air inlet groove 23 and the air outlet groove 25, a cold and hot circulation convection air duct is formed at the anti-scald handle assembly 2, so that the external low-temperature air enters the air isolation groove 5 through the air inlet groove 23, the air is heated and absorbs heat in the air isolation groove 5 to form relatively high-temperature air, and is discharged through the air outlet groove 25. With the flow of air, the heat of the anti-scald handle assembly 2 can be effectively taken away to achieve heat dissipation and cooling of the anti-scald handle assembly 2.

[0035] For the anti-scald handle assembly 2 and the door frame 3, the anti-scald handle assembly 2 and the door frame 3 are integrally formed to improve the integration degree and mechanical properties of the door assembly 1, and at the same time, it also conforms to the design concept of the integrated door frame handle in the prior art, that is, the present application still maintains the main form of the integrated door frame handle in the prior art, and aims to solve the problems existing in such an integrated door frame handle.

[0036] Correspondingly, the anti-scald handle assembly 2 includes an integrated handle 21, as shown in the accompanying drawings Figure 2 As shown, the anti-scald handle assembly 2 extends upward to form an extension, which can be regarded as an integrated handle 21, and the user can apply force to the integrated handle 21 with his hand when opening or closing the door assembly 1. At the same time, the heat of the integrated handle 21 can be taken away by the flow of air in the air isolation groove 5 to achieve heat dissipation and cooling of the integrated handle 21.

[0037] Furthermore, the anti-scalding handle assembly 2 includes an integrated handle 21 and a protrusion 22. The protrusion 22 is connected to the rear side wall of the integrated handle 21, and the air inlet groove 23 is provided on the side of the protrusion 22 away from the integrated handle 21. Thus, by providing the protrusion 22, on the one hand, when the user opens or closes the door assembly 1, their fingers can simultaneously contact the integrated handle 21 and the protrusion 22, increasing the force application area and facilitating user operation. On the other hand, the protrusion 22 itself can serve as a clear handle marker, allowing the user to visually recognize that the location of the protrusion 22 is the corresponding handle area, avoiding misoperation due to the user not knowing the handle's location. Thirdly, in addition to the heat dissipation and cooling of the integrated handle 21 as described in this application, the air inlet groove 23 in the protrusion 22 allows external air to flow from the protrusion 22 into the air isolation groove 5, which can promptly remove the heat from the protrusion 22, achieving heat dissipation and cooling of the protrusion 22.

[0038] Preferably, in the left-right direction, the protrusion 22 is preferably located in the middle of the integrated handle 21 to conform to the user's habit of the conventional door opening position.

[0039] As attached Figure 2 As shown, the height of the protrusion 22 in the vertical direction is denoted as H1, and the height of the integrated handle 21 in the vertical direction is denoted as H2. The ratio of H1 to H2 is 0.3-0.5. On the one hand, this ensures that the integrated handle 21 still has a certain height above the protrusion 22, providing a certain operating space for the user's fingers. On the other hand, it also ensures that the protrusion 22 has sufficient height so that the air intake slot 23 is not too narrow, which helps to improve the air intake efficiency at the air intake slot 23.

[0040] The protrusion 22 is provided with at least two air inlet slots 23, and a reinforcing rib 24 is provided between any two adjacent air inlet slots 23, which helps to increase the air flow into the air isolation slot 5. At the same time, with the provision of the reinforcing rib 24, it helps to improve the stress distribution of the protrusion 22, improve the mechanical strength of the protrusion 22, and also allows the protrusion 22 to be long enough in the left and right direction, and to open as many air inlet slots 23 as possible.

[0041] In the projection in the front-to-back direction, the exhaust groove 25 is located on the left and / or right side of the protrusion 22. This allows air to enter the air isolation groove 5 through the air intake groove 23 at the protrusion 22, and then flow a certain distance along the air isolation groove 5 to the exhaust groove 25 before being discharged. This not only ensures the orderly arrangement of the air intake groove 23 and the exhaust groove 25, but also guarantees the flow distance of the air within the air isolation groove 5.

[0042] Regarding the length of the protrusion 22 in the left-right direction, see attached... Figure 6As shown, the length of the protruding portion 22 in the left-right direction is denoted as W1, and the length of the integrated handle 21 in the left-right direction is denoted as W2, the ratio of W1 to W2 is 0.35-0.50, on the one hand, the protruding portion 22 has sufficient length, and more air inlet grooves 23 can be arranged, on the other hand, enough space is left on both sides of the protruding portion 22, so that more air outlet grooves 25 can be arranged, and the air can flow smoothly through the air inlet grooves 23, the air isolation grooves 5 and the air outlet grooves 25 in turn, avoiding the situation that the air inflow or outflow is not smooth, which helps to improve the heat dissipation efficiency of the anti-scald handle assembly 2.

[0043] The door assembly 1 further comprises an outer glass 4 arranged on the front side of the anti-scald handle assembly 2 and the door frame 3 and connected with the anti-scald handle assembly 2 and the door frame 3 respectively. The outer glass 4 is arranged on the front surface of the anti-scald handle assembly 2 and the door frame 3, on the one hand, the user can directly see the inner cavity of the cooking device through the outer glass 4, on the other hand, a certain protection effect can be formed on the outer side of the door assembly 1, and the aesthetic appearance is also improved.

[0044] Since the rear side of the integrated handle 21 is the contact position of the user's fingers, the air outlet groove 25 is arranged on the front side of the anti-scald handle assembly 2, one end of the air outlet groove 25 is communicated with the air isolation groove 5, and the other end is communicated with the external environment, so that the air discharged from the air outlet groove 25 can avoid the rear side of the integrated handle 21, and the user can not feel the flow of the related air when opening the door, so as to ensure the user experience.

[0045] In order to further improve the aesthetic appearance, in addition to arranging the opening (inlet) of the air inlet groove 23 on the rear side of the protruding portion 22, the outlet of the air outlet groove 25 is communicated with the external environment through the assembly gap (not shown) between the outer glass 4 and the anti-scald handle assembly 2, so that the user cannot see any opening on the front side of the door assembly 1, and the aesthetic appearance of the door assembly 1 and the entire cooking device is improved.

[0046] The application further provides a cooking device comprising the door assembly 1 and a cavity, and the door assembly 1 is connected with the cavity 3 in an opening and closing manner. The cooking device can be a microwave oven, a steaming oven or other cooking devices provided with the door assembly 1.

[0047] In the utility model, for any cooking device, the door assembly 1 in the embodiment can be included. On the basis of the technical content provided in the embodiment, the cooking device further comprises a shell, an electric control assembly and other conventional components, and these conventional components are prior art, so no further description is made here.

[0048] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
