Detailed Description

The technical solutions of the present utility model will be clearly and completely described in connection with the embodiments, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1 and fig. 2, a door body provided in an embodiment of the present utility model may include: and a connecting frame to which at least three layers of boards 100 are connected, which are arranged at intervals from inside to outside. The plate 100 may be made of glass. An air duct for heat dissipation is formed between the inner and outer adjacent two-layer boards 100.

The number of the air channels is at least two. At least one air channel is in a conducting state, and air flow in the air channel in the conducting state can flow freely; at least one air duct is internally provided with a blocking structure 110, the blocking structure 110 blocks the air duct where the blocking structure is located, a part of the blocked air duct is communicated with the outside, and air flow in the blocked air duct stagnates and cannot pass through. It should be noted that the blocking structure 110 forms a blocking structure only on a portion of the air duct, and does not completely seal the gap forming the air duct around.

When the door body is in a closed state, after the heat dissipation mechanism on the cooking equipment is started, the air channel which is not blocked in the door body can flow with air flow to form heat dissipation air flow. The air flow in the blocked air duct is fixed, so that the heat transfer speed from inside to outside is reduced; meanwhile, when the total negative pressure in the door body is fixed, the air duct is blocked by the blocking structure, so that the airflow speed of the air duct which is not blocked by the blocking structure is increased, the heat dissipation capacity of the part of airflow is improved, the heat transferred to the outermost side of the door body is reduced, and the temperature of the outermost side of the door body is reduced.

The plate 100 includes oppositely disposed upper and lower edges. An air duct is formed between two adjacent plate bodies 100, an air outlet is formed between two adjacent upper edges, and an air inlet is formed between two adjacent lower edges. The connecting frame is provided with an exhaust hole 230 for communicating the inside and the outside of the door body, compared with the air inlet, the exhaust hole 230 is closer to the air outlet, and air flow flowing out from the air outlet can flow out from the exhaust hole 230. When the blocking structure 110 is not present, the air flow may flow into the door from bottom to top and then flow through the air duct to be discharged from the air discharge hole 230. It should be noted that the main body of the cooking apparatus corresponding to the door body has an inlet 310 corresponding to the exhaust hole 230, and a heat dissipation mechanism is connected to the other side of the inlet 310, and the heat dissipation mechanism can generate negative pressure at the inlet 310, so that the air flow flows through the door body and then enters the main body.

In one embodiment, the blocking structure 110 is disposed in the air duct closest to the inner side of the door body, that is, the blocking structure 110 is disposed between two adjacent plate bodies 100 closest to the inner side of the door body, and the blocking structure 110 may be located at the air inlet of the air duct where the blocking structure is located; alternatively, the blocking structure 110 may be located at an air outlet of the air duct where the blocking structure is located; alternatively, the blocking structure 110 may be located between the air inlet and the air outlet of the air duct in which it is located. Since the two-layer plate 100 is closest to the inner side, i.e., closest to the heat source (cooking cavity 800), the blocking structure 110 is disposed between the two-layer plate 100, so that the heat transferred to the door body is directly transferred to the door body, and after the heat transferred to the door body is reduced, the heat transferred to the outermost surface of the door body is also reduced.

In another embodiment (the solution of this embodiment), the blocking structure 110 is filled between two adjacent plates 100 closest to the outer side of the door body, and the blocking structure 110 is located at the air outlet, so that the air in the blocked air duct is relatively static, and local air flow is avoided. The two-layer plate 100 is closest to the outer side of the door body, i.e. closest to the user contact surface, and can directly avoid scalding the user.

When the door body is in a closed state, after the heat dissipation mechanism on the cooking device is started, negative pressure is generated at the exhaust hole 230, air flow flowing from the lower edge to the upper edge (from bottom to top) is formed between the adjacent two plate bodies 100 which are not sealed by the blocking structure 110, the air flow is converged and then discharged out of the door body from the exhaust hole 230, and if the blocking structure 110 is arranged between the adjacent two plate bodies 100 closest to the inner side or between the two plate bodies 100 closest to the outer side, the air flow between the two plate bodies 100 can be reduced, and the heat transfer speed from the inner side to the outer side is further reduced; meanwhile, when the negative pressure of the exhaust hole 230 is constant, the blocking structure 110 is used to block the original air outlet, so that the flow speed of the air flow at the air inlet which is not blocked by the blocking structure 110 is increased, the heat dissipation capacity of the air flow is improved, the heat transferred to the outermost plate 100 is reduced, and the temperature of the outermost plate 100 of the door is reduced.

The air duct in the conducting state and the air duct in the blocking state are arranged adjacently, so that uniform flow of air flow can be met, and heat transfer from the conducting air duct to the non-conducting air duct can be reduced. The non-conducting air duct forms a barrier, and heat on the inner side of the air duct is difficult to transfer to the outer side under the barrier.

The blocking structure 110 comprises a sealing strip, a clamping groove 111 is formed in the sealing strip, the clamping groove 111 is located at the front side or the rear side of the sealing strip, the sealing strip is clamped between two adjacent plate bodies 100, and the clamping groove 111 is fastened with the upper edge of one plate body 100.

As shown in fig. 3, in the present embodiment, the sealing strip extends in the left-right direction and is clamped between the two plate bodies 100, in order to facilitate the installation of the blocking structure 110 and prevent the blocking structure 110 from deviating from the working position, a clamping groove 111 is provided on the sealing strip, the opening of the clamping groove 111 faces downward and is buckled on the upper edge of one of the plate bodies 100, and the door body is repeatedly opened and closed, so that the blocking structure 110 is not separated from the installation position.

The connecting frame comprises two parallel side brackets 240 arranged at intervals, the extending direction of the side brackets 240 is perpendicular to the upper edge and the lower edge, the side brackets 240 are connected with the back surface of the outermost plate body 100, and the plate bodies 100 except the outermost plate body 100 are connected with the side brackets 240.

In this embodiment, two side brackets 240 are disposed at a left-right interval, the side brackets 240 and the outermost plate 100 may be connected together by gluing, and a plurality of connection portions 241 are formed on the side brackets 240 for sequentially connecting other plate 100.

The connection frame includes an upper bracket 210, the upper bracket 210 includes an upwardly facing top surface and a rearwardly facing back plate, and the exhaust hole 230 is provided in the back plate.

The upper bracket 210 may be connected to the outermost plate body 100 or may be connected to the side bracket 240. The innermost plate body 100 may be abutted against the outer surface of the back plate of the upper bracket 210, an elastic limiting block 250 may be clamped between the innermost plate body 100 and the outermost plate body 100, the limiting block 250 may have a plurality of mounting grooves, the plurality of mounting grooves are arranged at intervals along the inner and outer directions, and each plate body 100 located between the innermost plate body and the outermost plate body may be inserted into the mounting groove in a one-to-one correspondence manner, so that a certain gap is maintained between each plate body 100. In this embodiment, the number of the limiting blocks 250 is two, and the limiting blocks are respectively disposed at the upper left corner and the upper right corner of the board body 100.

In order to improve the tightness, the upper bracket 210 is connected with the outermost plate body 100, and a sealing structure 220 is arranged between the upper bracket 210 and the outermost plate body 100, the sealing structure 220 can also be a sealing strip, a groove is formed on the upper bracket 210 by bending through sheet metal processing, the opening of the groove faces the outermost plate body 100, the sealing structure 220 is placed in the groove, and the sealing structure 220 is abutted with the inner surface of the outermost plate body 100, so that a gap between the sealing structure and the outermost plate body 100 is reduced.
