Description

Technical Field

[0001] The utility model relates to the technical field of ovens, in particular to an oven door and an oven. Background Art

[0002] Ovens are commonly used household appliances. There are ovens with a single baking function, and there are also steam ovens with both baking and steaming functions. The national standard now requires that the temperature rise of the glass surface of the steamer is less than 60K. 60K plus the room temperature of 25℃, the surface temperature requirement is less than 85℃. However, if a person touches the outer surface of the 70℃ glass for 3 seconds, he will feel too hot and retract his hand. The national standard has loose requirements for surface temperature rise, resulting in most models on the market being able to meet the temperature rise, but in fact the surface temperature rise is still very high. The market often reports that users have experienced high temperatures in the door glass after using the product, resulting in burns. Currently, there are three ways to reduce the temperature rise of the door surface:

[0003] 1. Reasonably control the number of glass layers and the distance between the glass on the oven door;

[0004] 2. Add Low-e film to reduce the heat radiation from the oven cavity to the outermost glass;

[0005] 3. Design the cold air duct structure: optimize the thermal convection structure of the oven door cavity.

[0006] Currently, the third solution is the most ideal. The cold air duct is combined with the large through-hole system on the surface of the door body for heat dissipation, which has the most ideal heat dissipation effect. However, the design of the openings on the surface of the door body makes it easy for residues to fall into the door body during use. Users cannot clean it, which seriously affects the product appearance and user experience.

[0032] like Figure 1 , Figure 2 , Figure 3 As shown, an embodiment of the utility model provides an oven door body, including a door body 1, wherein a vertical cooling cavity A is provided in the door body 1, and the top surface and bottom surface of the door body 1 are respectively provided with a top opening 11 and a bottom opening 12 corresponding to the cooling cavity A. The top opening 11 is covered with an air outlet seat 2 to close the top opening 11, and an air outlet 21 is provided on the air outlet seat 2 for discharging air in the cooling cavity A. A baffle 3 and an elastic structure 4 are provided on the inner side of the air outlet seat 2. When the door body 1 is opened, the elastic structure 4 enables the baffle 3 to block the air outlet 21. When the door body 1 is closed, the baffle 3 can abut against the protrusion 61 on the oven cavity and move away from the air outlet seat 2 to release the blockage of the air outlet 21 and open the air outlet 21.

[0033] The principle of reducing the temperature rise on the surface of the oven door provided by the utility model is that cold air enters the cooling cavity A in the door body 1 from the bottom opening 12 of the door body 1, and is sucked away by the fan on the top of the oven from the top opening 11 of the door body 1. In this process, the heat conducted from the side of the door body 1 close to the oven cavity (the side close to the heat source) is taken away, and the surface temperature rise on the outside of the door body 1 (the side close to the user) is reduced. During the use of the oven, the door body 1 abuts against the oven cavity to close the oven cavity. At this time, the protrusion 61 on the oven cavity passes through the air outlet 21 and abuts against the baffle 3. The baffle 3 is pushed by the protrusion in the direction away from the air outlet seat 2, and the air outlet 21 of the air outlet seat 2 is released, so that the air in the cooling cavity A can be sucked away from the air outlet 21 by the fan. When the oven needs to be opened after use, the baffle 3 no longer contacts the protrusion 61 on the oven cavity. Under the action of the elastic structure 4, the baffle 3 clings to the inner side of the air outlet seat 2, thereby restoring the blockage of the air outlet 21 of the air outlet seat 2, preventing residues and debris from accidentally falling into the cooling cavity A and blocking the cooling cavity A, thereby affecting the product appearance and user experience.

[0034] In one embodiment of the present invention, Figure 2 , Figure 3 As shown, the door body 1 includes a first door panel 13, a second door panel 14 and a third door panel 15 which are arranged in sequence from the inside to the outside. A heat-insulating cavity B is formed between the first door panel 13 and the second door panel 14, and a cooling cavity A is formed between the second door panel 14 and the third door panel 15. In this embodiment, the first door panel 13 is close to one side of the oven cavity (the side close to the heat source), and the third door panel 15 is located on the outside of the door body 1 (the side close to the user). The heat-insulating cavity B can reduce the heat conducted to the cooling cavity A inside the door body 1, and further reduce the surface temperature rise on the outside of the door body 1. In this embodiment, the first door panel 13, the second door panel 14 and the third door panel 15 are all heat-insulating glass panels, and the ends are fixedly connected to form the door body. When the oven is cooking, the top cooling fan works, and cold air is continuously sucked in from the bottom opening 12, and the heat is taken out when passing through the cooling cavity A formed between the second door panel 14 and the third door panel 15. After the heat and cold air enter the air duct at the top of the oven, the temperature is further reduced by the mixing action of the fan (the cooling fan not only draws cold air from the cooling cavity A of the door body, but also draws cold air from all around the middle plate), and the mixed gas and heat are discharged from the air outlet end of the air duct.

[0035] like Figure 2 , Figure 3As shown, the heat-insulating cavity B formed between the first door panel 13 and the second door panel 14 is relatively close to the oven cavity and has relatively high heat. To prevent heat from radiating to the third door panel 15, the top of the heat-insulating cavity B is closed to further reduce the surface temperature rise of the outer side of the door body 1 (the third door panel 15). In this embodiment, a sealing strip 5 is provided on the top of the heat-insulating cavity B, and the bottom of the heat-insulating cavity B is connected to the bottom opening 12.

[0036] In one embodiment of the present invention, Figure 3 As shown, the elastic structure 4 includes a base 41 and a guide rod 42. The base 41 is fixedly arranged on the inner wall of the door body 1. In this embodiment, the base 41 is arranged on the inner wall of the third door panel 15. The guide rod 42 is arranged on the base 41 and extends toward the air outlet seat 2. In this embodiment, the air outlet 21 is a plurality of slots arranged along the width direction of the door body, and a plurality of elastic structures 4 are arranged correspondingly along the length direction of the air outlet 21. The baffle 3 is sleeved on the guide rod 42 and can slide relative to the guide rod 42, and a spring 43 is sleeved on the outer periphery of the guide rod 42 between the baffle 3 and the base 41. When the door body 1 is closed, the shutter 3 abuts against the protrusion 61 on the front side of the oven cavity, and is forced to move along the axial direction of the guide rod 42 in the direction away from the air outlet seat 2 while compressing the spring 43, thereby releasing the blockage of the air outlet 21. At this time, the air in the cooling cavity A can be sucked away by the fan, while taking away the heat conducted from the inside of the door body 1, thereby reducing the surface temperature rise on the outside of the door body 1. When the door body 1 is opened, the shutter 3 no longer abuts against the protrusion 61 on the front side of the oven cavity. Under the action of the spring 43, the shutter 3 moves along the axial direction of the guide rod 42 in the direction close to the air outlet seat 2 and clings to the inside of the air outlet seat 2, thereby blocking the air outlet 21. At this time, the top of the cooling cavity A is blocked, thereby preventing residues and debris from accidentally falling into the cooling cavity A, blocking the cooling cavity A, and affecting the product appearance and user experience.

[0037] like Figure 4 As shown, the utility model further provides an oven, comprising the above-mentioned oven door body. Specifically, the oven also includes an oven cavity 6, which is combined with the door body 1 to realize the basic functions of the oven. The oven cavity 6 is provided with a protrusion 61 corresponding to the shield 3, for example, arranged at the front top of the oven cavity 6, so as to perform a force-applying operation on the shield 3. In one embodiment of the utility model, the protrusion 61 can be a support rod.

[0038] Furthermore, an air duct 7 is provided on the top of the oven cavity 6, and a fan 71 is provided in the air duct 7, and one end (air inlet end) of the air duct 7 corresponds to the air outlet 21 of the air outlet seat 2, so as to extract the air in the cooling cavity A, speed up the outflow of air in the cooling cavity A, take away more heat in the cooling cavity A, and reduce the surface temperature rise on the outside of the door body 1.

[0039] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
