The furnace door assembly includes an outer door body assembly, a first door plate, a second door plate, and an inner door body. The outer door body assembly, the first door plate, and the second door plate make the furnace door assembly a multi-layer door body structure.

[0008] Specifically, when the furnace door assembly is installed on the box body of the cooking utensil, the side of the outer door body assembly facing the box body is the first side of the outer door body assembly, and the first door plate is connected to the outer door body assembly.

[0009] Further, the second door plate is installed and fixed by cooperation of the inner door body and the outer door body assembly. Specifically, the inner door body is located at the first side of the outer door body assembly, at least a part of the inner door body is located in the box when the oven door assembly closes the box, and the inner door body is connected to the outer door body assembly. The second door plate is located between the first door plate and the inner door body, and the second door plate is located on the inner side of the first door plate when the oven door assembly closes the box, that is, the second door plate is located on the side of the first door plate away from the outside. At least a part of the outer door body protrudes from the surface of the first door plate in the direction towards the second door plate, and the outer door body assembly and the inner door body protruding from the surface of the first door plate cooperate with the two sides of the second door plate respectively, so as to jointly clamp the second door plate to install and fix the second door plate. The second door plate is located on the side of the first door plate away from the outer door body assembly, and the second door plate faces the inside of the box when the oven door assembly closes the box.

[0010] Further, at least a part of the outer door body assembly, the first door plate and the second door plate can transmit light, and the user can observe the state of the food in the box through the outer door body assembly, the first door plate and the second door plate. The first door plate and the second door plate can be made of high-temperature-resistant glass.

[0011] By arranging the outer door body assembly, the first door plate and the second door plate in the oven door assembly, the oven door assembly can form a multi-layer door body structure, improve the heat insulation of the oven door assembly, and further improve the heat preservation of the cooking utensil as a whole. Compared with the complex door body structure in the related art, the second door plate is clamped by the outer door body assembly and the inner door body in the present application, which reduces the installation difficulty of the second door plate, simplifies the structure of the oven door assembly, and reduces the production cost of the oven door assembly. And since at least a part of the outer door body assembly, the first door plate and the second door plate can transmit light, the user can observe the state of the food in the box through the oven door assembly, so that the oven door assembly has a visual function.

[0012] According to the oven door assembly of the present application, the following technical features can be further provided:

[0013] In some technical solutions, optionally, the outer door body assembly comprises: a third door plate, the third door plate being capable of transmitting light; an outer door body, the second door plate being located at the first side of the outer door body, and the third door plate being located at the second side of the outer door body, the second side of the outer door body having a glue injection groove for accommodating an adhesive, and the third door plate being adhered to the second side of the outer door body by the adhesive.

[0014] In the technical solution, the structure of the outer door body assembly is limited. The outer door body assembly comprises an outer door body and a third door plate. The second door plate is located on the first side of the outer door body, and the third door plate is located on the second side of the outer door body. When the oven door assembly closes the box body, the third door plate is exposed to the box body and is arranged towards the outside. The second side of the outer door body has a glue injection groove capable of accommodating an adhesive. The third door plate is bonded to the second side of the outer door body by the adhesive to install and fix the third door plate. By using the bonding method to install and fix the third door plate, other connecting parts can be avoided on the outer door body, and the structure of the product is simplified.

[0015] Further, the third door plate can transmit light, so that the user can observe the state of the food materials in the box body through the oven door assembly, and the oven door assembly has a visualization function.

[0016] In some technical solutions, the oven door assembly further comprises a first sealing member installed on the peripheral side of the second door plate. A part of the first sealing member is located on the side of the second door plate facing the first door plate, and a part of the first sealing member is located on the side of the second door plate away from the first door plate. The outer door body and the inner door body press the first sealing member to seal the gap between the inner door body and the second door plate and the gap between the outer door body and the second door plate.

[0017] In the technical solution, the structure of the oven door assembly is further limited. In order to improve the sealing performance of the oven door assembly, the first sealing member is arranged in the oven door assembly. Understandably, when the second door plate is installed between the inner door body and the outer door body, there will be a certain gap between the inner door body and the second door plate and between the outer door body and the second door plate. The water vapor in the box body is easy to enter the oven door assembly through these gaps, which will cause the water vapor to erode other components in the oven door assembly, and also cause the third door plate, the first door plate and the second door plate to generate a foggy surface, thereby making it difficult for the user to observe the food materials in the box body. In order to avoid the above problems, the first sealing member is arranged in the oven door assembly, which can improve the sealing performance of the oven door assembly.

[0018] Specifically, the first sealing member is mounted on the peripheral side of the second door plate, and wraps the edge of the second door plate, and a part of the first sealing member is located on the side of the second door plate facing the first door plate, and the outer door body extrudes this part of the first sealing member to seal the gap between the second door plate and the outer door body. A part of the first sealing member is located on the side of the second door plate away from the first door plate, and the inner door body extrudes this part of the first sealing member to seal the gap between the second door plate and the inner door body. In this way, the sealing performance of the oven door assembly can be improved, the water vapor in the box body can be prevented from entering the oven door assembly through the gap between the outer door body, the inner door body and the second door plate, the components in the oven door assembly can be prevented from being corroded by water vapor, the service life of each component in the oven door assembly is improved, and the user can clearly observe the food in the box body through the oven door assembly, thereby improving the user experience.

[0019] In some technical solutions, the first sealing member can be made of high-temperature-resistant rubber.

[0020] In some technical solutions, the oven door assembly is used in a cooking appliance, and the cooking appliance includes a box body, and the oven door assembly further includes a second sealing member, the side of the inner door body away from the outer door body is provided with a sealing groove, and the second sealing member is mounted in the sealing groove, and the second sealing member seals the gap between the inner door body and the box body when the oven door assembly closes the box body.

[0021] In this technical solution, the structure of the oven door assembly is further limited. The oven door assembly is used in a cooking appliance, and the cooking appliance includes a box body, and the oven door assembly is mounted on the box body and can open or close the box body. When the oven door assembly closes the box body, if the gap between the oven door assembly and the box body is not sealed, the sealing performance of the cooking appliance will be poor, and the heat in the cooking cavity will easily escape to the outside through the gap between the oven door assembly and the box body. On the one hand, this will reduce the cooking efficiency of the cooking appliance and slow down the temperature rise in the box body, and on the other hand, the heat leaked from the cooking appliance will easily cause burns to the user. In order to avoid the above problems, the second sealing member is further provided in the oven door assembly.

[0022] Specifically, the side of the inner door body away from the outer door body is provided with a sealing groove, and the second sealing member is mounted in the sealing groove and exposed on the surface of the inner door body. When the oven door assembly closes the box body, the second sealing member seals the gap between the inner door body and the box body. In this way, the heat in the box body can be prevented from overflowing to the outside through the gap between the inner door body and the box body, the sealing performance of the oven door assembly on the box body is improved, the cooking efficiency of the cooking appliance is improved, and the user can be prevented from being burned, thereby improving the safety of the cooking appliance.

[0023] In a possible technical solution, when the furnace door assembly closes the cabinet, the second sealing element is located in the cabinet, and the outer circumferential surface of the second sealing element is attached to the wall surface of the cabinet to seal the gap between the furnace door assembly and the cabinet. The second sealing element can be made of high-temperature-resistant rubber.

[0024] In some technical solutions, the bottom wall of the glue injection groove is provided with a plurality of glue overflow holes penetrating through the outer door body.

Before the third door plate is installed on the outer door body, the adhesive is injected into the glue injection groove, and then the third door plate is attached to the surface of the second side of the outer door body. At this time, the adhesive in the glue injection groove adheres to the surface of the third door plate, and the third door plate extrudes the adhesive in the glue injection groove. Since the glue overflow holes penetrate through the outer door body, a small amount of adhesive will flow to the first side of the outer door body through the glue overflow holes. After the adhesive solidifies, the third door plate is adhered to the second side of the outer door body by the adhesive. Since a small amount of adhesive flows to the first side of the outer door body through the glue overflow holes, at least part of the glue overflow holes form protrusions on the first side of the outer door body, which are formed by the solidification of the adhesive. The size of these protrusions is greater than the hole diameter of the glue overflow holes, so that these protrusions can limit the solidified adhesive and prevent the solidified adhesive from falling off from the glue injection groove. Moreover, by providing a plurality of glue overflow holes on the bottom wall of the glue injection groove, the adhesive can overflow from the glue overflow holes to the first side of the outer door body when it is extruded by the third door plate. Thus, the adhesive can be prevented from overflowing from the gap between the third door plate and the outer door body, and the third door plate can be firmly adhered to the outer door body.

The number of limiting pieces is multiple, and the multiple limiting pieces are connected to the mounting bracket and surround the circumferential side of the mounting bracket. In this way, the limiting effect of the limiting pieces on the second door plate can be improved, so that the second door plate can be kept in the correct position.

[0034] The mounting rack is arranged on the outer door body, and the first door plate is mounted and fixed through the mounting steps and the clamping pieces on the mounting rack.

[0035] In some technical solutions, the oven door assembly further comprises a display support mounted on the outer door body, and the display support is located at the bottom of the mounting rack; and a display mounted on the display support, and at least a part of the display is attached to the side of the third door plate facing the first door plate.

The second door plate 140 is located at the side of the first door plate 130 facing away from the outer door body assembly 200, and the second door plate 140 faces the inside of the box body when the furnace door assembly 100 closes the box body.

[0085] Further, at least part of the outer door body assembly 200, the first door plate 130 and the second door plate 140 are transparent, and a user can observe the state of food in the box through the outer door body assembly 200, the first door plate 130 and the second door plate 140. The first door plate 130 and the second door plate 140 can be made of high-temperature-resistant glass.

[0086] By arranging the outer door body assembly 200, the first door plate 130 and the second door plate 140 in the oven door assembly 100, the oven door assembly 100 can form a multi-layer door structure, thereby improving the heat insulation of the oven door assembly 100 and the heat preservation of the cooking appliance as a whole. Compared with the complex door structure in the related art, the second door plate 140 is clamped by the outer door body assembly 200 and the inner door body 150 in the present application, which reduces the installation difficulty of the second door plate 140, simplifies the structure of the oven door assembly 100 and reduces the production cost of the oven door assembly 100. Moreover, since at least part of the outer door body assembly 200, the first door plate 130 and the second door plate 140 are transparent, the user can observe the state of food in the box through the oven door assembly 100, and the oven door assembly 100 has a visual function.

[0087] In some embodiments, as shown in Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 and Figure 11 , the outer door body assembly 200 includes a third door plate 120, the third door plate 120 being transparent; an outer door body 110, the second door plate 140 being located on a first side of the outer door body 110, and the third door plate 120 being located on a second side of the outer door body 110, the second side of the outer door body 110 having a glue injection groove 111 for accommodating an adhesive, and the third door plate 120 being bonded to the second side of the outer door body 110 by the adhesive.

[0088] In this embodiment, the structure of the outer door body assembly 200 is limited. The outer door body assembly 200 includes an outer door body 110 and a third door plate 120, the second door plate 140 being located on a first side of the outer door body 110, and the third door plate 120 being located on a second side of the outer door body 110, the third door plate 120 being exposed to the box and arranged towards the outside when the oven door assembly 100 closes the box. The second side of the outer door body 110 has a glue injection groove 111, the glue injection groove 111 being capable of accommodating an adhesive, and the third door plate 120 being bonded to the second side of the outer door body 110 by the adhesive to install and fix the third door plate 120. By bonding the third door plate 120, other connecting members can be avoided on the outer door body 110, and the structure of the product is simplified.

[0089] Further, the third door plate 120 is capable of transmitting light, so that the user can observe the state of the food in the box through the oven door assembly 100, and the oven door assembly 100 has a visual function. The third door plate 120 can be made of high-temperature-resistant glass.

[0090] In some embodiments, as shown in Figure 2 , Figure 4 and Figure 11 , the oven door assembly 100 further comprises a first sealing member 141 installed on the peripheral side of the second door plate 140, a part of the first sealing member 141 is located on the side of the second door plate 140 facing the first door plate 130, and a part of the first sealing member 141 is located on the side of the second door plate 140 away from the first door plate 130. The outer door body 110 and the inner door body 150 extrude the first sealing member 141, so that the first sealing member 141 seals the gap between the inner door body 150 and the second door plate 140 and the gap between the outer door body 110 and the second door plate 140.

[0091] In this embodiment, the structure of the oven door assembly 100 is further limited. In order to improve the sealing performance of the oven door assembly 100, the present application further provides a first sealing member 141 in the oven door assembly 100. Understandably, when the second door plate 140 is installed between the inner door body 150 and the outer door body 110, there will be a certain gap between the inner door body 150 and the second door plate 140 and between the outer door body 110 and the second door plate 140. The water vapor in the box is easy to enter the oven door assembly 100 through these gaps, which will cause the water vapor to erode other components in the oven door assembly 100, and also cause the third door plate 120, the first door plate 130 and the second door plate 140 to generate a fog surface, thereby making it difficult for the user to observe the food in the box. In order to avoid the above problems, the present application provides a first sealing member 141 in the oven door assembly 100, which can improve the sealing performance of the oven door assembly 100.

[0092] Specifically, the first sealing member 141 is mounted on the circumferential side of the second door plate 140, the first sealing member 141 covers the edge of the second door plate 140, a part of the first sealing member 141 is located on the side of the second door plate 140 facing the first door plate 130, and the outer door body 110 extrudes this part of the first sealing member 141 to seal the gap between the second door plate 140 and the outer door body 110. A part of the first sealing member 141 is located on the side of the second door plate 140 away from the first door plate 130, and the inner door body 150 extrudes this part of the first sealing member 141 to seal the gap between the second door plate 140 and the inner door body 150. In this way, the sealing performance of the oven door assembly 100 can be improved, the water vapor in the box can be prevented from entering the oven door assembly 100 through the gap between the outer door body 110, the inner door body 150 and the second door plate 140, the components in the oven door assembly 100 can be prevented from being corroded by water vapor, the service life of each component in the oven door assembly 100 is improved, and the user can clearly observe the food in the box through the oven door assembly 100, thereby improving the user experience.

[0093] In some embodiments, the first sealing member 141 can be made of high-temperature-resistant rubber.

[0094] In some embodiments, the first sealing member 141 can be made of high-temperature-resistant rubber. Figure 1 、 Figure 2 、 Figure 4 、 Figure 9 and Figure 11 As shown in the above embodiments, the oven door assembly 100 is used in a cooking appliance, and the cooking appliance includes a box body. The oven door assembly 100 further includes a second sealing member 152. The inner door body 150 is provided with a sealing groove 151 away from the outer door body 110. The second sealing member 152 is mounted in the sealing groove 151. When the oven door assembly 100 closes the box body, the second sealing member 152 seals the gap between the inner door body 150 and the box body.

[0095] In this embodiment, the structure of the oven door assembly 100 is further limited. The oven door assembly 100 is used in a cooking appliance, and the cooking appliance includes a box body. The oven door assembly 100 is mounted on the box body and can open or close the box body. When the oven door assembly 100 closes the box body, if the gap between the oven door assembly 100 and the box body is not sealed, the sealing performance of the cooking appliance will be poor, and the heat in the cooking cavity will easily be dissipated to the outside through the gap between the oven door assembly 100 and the box body. On the one hand, this will reduce the cooking efficiency of the cooking appliance and slow down the temperature rise in the box body. On the other hand, the heat leaked from the cooking appliance will easily cause the user to be scalded. In order to avoid the above problems, the second sealing member 152 is further provided in the oven door assembly 100.

[0096] Specifically, the side of the inner door body 150 away from the outer door body 110 is provided with a sealing groove 151, and a second sealing member 152 is installed in the sealing groove 151 and exposed on the surface of the inner door body 150. When the oven door assembly 100 closes the cabinet, the second sealing member 152 seals the gap between the inner door body 150 and the cabinet. In this way, the heat in the cabinet can be prevented from overflowing to the outside through the gap between the inner door body 150 and the cabinet, the sealing performance of the oven door assembly 100 on the cabinet is improved, the cooking efficiency of the cooking appliance is improved, and the user can also be prevented from being scalded, and the safety of the cooking appliance is improved.

[0097] In a possible embodiment, when the oven door assembly 100 closes the cabinet, the second sealing member 152 is located in the cabinet, and the outer peripheral surface of the second sealing member 152 is attached to the wall surface of the cabinet to seal the gap between the oven door assembly 100 and the cabinet. The second sealing member 152 can be made of high-temperature-resistant rubber.

[0099] In this embodiment, the structure of the glue injection groove 111 is limited. The bottom wall of the glue injection groove 111 is provided with a plurality of glue overflow holes 112, and the glue overflow holes 112 penetrate through the outer door body 110. Before the third door plate 120 is installed on the outer door body 110, adhesive is first injected into the glue injection groove 111, and then the third door plate 120 is attached to the surface of the second side of the outer door body 110. At this time, the adhesive in the glue injection groove 111 adheres to the surface of the third door plate 120, and the third door plate 120 extrudes the adhesive in the glue injection groove 111. Since the glue overflow holes 112 penetrate through the outer door body 110, a small amount of adhesive will flow to the first side of the outer door body 110 through the glue overflow holes 112. After the adhesive solidifies, the third door plate 120 is adhered to the second side of the outer door body 110 by the adhesive. Since a small amount of adhesive flows to the first side of the outer door body 110 through the glue overflow holes 112, at least part of the glue overflow holes 112 form protrusions on the first side of the outer door body 110 by the solidification of the adhesive. The size of the protrusions is greater than the hole diameter of the glue overflow holes 112, so that the protrusions can limit the solidified adhesive and prevent the solidified adhesive from falling off from the glue injection groove 111. Furthermore, by providing a plurality of glue overflow holes 112 on the bottom wall of the glue injection groove 111, the adhesive can overflow from the glue overflow holes 112 to the first side of the outer door body 110 when it is extruded by the third door plate 120, so that the adhesive can be prevented from overflowing from the gap between the third door plate 120 and the outer door body 110, and the third door plate 120 can be firmly adhered to the outer door body 110.

[0100] In some embodiments, as shown in Figure 5 , the number of glue injection grooves 111 is at least two, and the at least two glue injection grooves 111 are respectively close to two sides of the outer door body 110.

[0101] In this embodiment, the glue injection grooves 111 are further limited. The number of glue injection grooves 111 is at least two, and the at least two glue injection grooves 111 are respectively close to two sides of the outer door body 110. In this way, the third door plate 120 can be balanced in overall stress, and the third door plate 120 can be firmly bonded to the outer door body 110.

[0102] In a possible embodiment, the number of glue injection grooves 111 is two, the two glue injection grooves 111 are respectively close to left and right sides of the outer door body 110, the two glue injection grooves 111 are symmetrically arranged relative to a center line of the outer door body 110, and the two glue injection grooves 111 are of the same shape. A part of any glue injection groove 111 is close to a top of the outer door body 110, and another part of any glue injection groove 111 is close to a side edge of the outer door body 110.

[0103] In some embodiments, as shown in Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 11 , the first side of the outer door body 110 has at least one clamping piece 113, and the first door plate 130 is clamped to the outer door body 110 by the clamping piece 113.

[0104] In this embodiment, the structure of the outer door body 110 is limited. The outer door body 110 has at least one clamping piece 113, and the first door plate 130 is clamped to the first side of the outer door body 110 by the clamping piece 113 to install and fix the first door plate 130. Specifically, the outer door body 110 has a mounting step 116, the first door plate 130 is installed on the mounting step 116, one side of the first door plate 130 facing the third door plate 120 is attached to the mounting step 116, and the other side of the first door plate 130 away from the third door plate 120 is clamped and limited by the clamping piece 113. The clamping piece 113 and the mounting step 116 respectively cooperate with two sides of the first door plate 130 to install and fix the first door plate 130. The number of clamping pieces 113 can be multiple, and the multiple clamping pieces 113 along the circumference of the first door plate 130 are respectively clamped to the edges of the first door plate 130. In this way, the installation stability of the first door plate 130 can be improved.

[0105] By setting the clamping piece 113 on the outer door body 110, the first door plate 130 can be clamped on the outer door body 110 through the clamping piece 113. Compared with the complex door body structure in the related art, the first door plate 130 is installed through the clamping piece 113, which reduces the installation difficulty of the first door plate 130, simplifies the structure of the oven door assembly 100, and reduces the production cost of the oven door assembly 100.
