Description

Technical Field

[0001] The invention relates to the technical field of steaming and baking cooking machines, in particular to a door assembly and a steaming and baking cooking machine. Background Art

[0002] Existing steam-bake cooking machines use a door sealing ring and a glass sealing structure inside the door body. When the steam function is working, the steam generated is sealed in the inner pot cavity by the door sealing ring made of silicone. When the inner pot is full of steam, such as in normal working state or just after finishing work, when the door body is opened, a large amount of steam will be ejected through the gap between the door body and the inner pot. At this time, the steam pressure is too high, causing a large amount of steam to flow toward the user.

[0003] Steam rushing towards the user's face may cause burns to the palm or arm when opening the door, and when using the steam function, the user cannot guarantee that the door is opened quickly every time to avoid the gushing steam. In addition, some users will open the door at a small angle to prevent the steam in the inner pot from rushing towards the user's face when opening the door, and release the steam in the inner pot in advance through this action, but this action is more likely to cause burns to the palm. Summary of the invention

[0004] Since the existing steam-bake cooking machine can easily burn the palms and arms of the user due to steam blowing in the face when the door is opened, it is necessary to provide a door assembly and a steam-bake cooking machine.

[0005] Door assembly for a steam-oven cooking machine, comprising:

[0006] A door body, wherein the door body has a rotating end and a handle end that are far away from each other, and the door body is further provided with a receiving groove located between the rotating end and the handle end;

[0007] An airbag, the airbag being installed in the receiving groove, and a first air hole being formed on a side of the airbag close to the handle end; and

[0008] An inner plate, the inner plate is arranged at the notch of the accommodating groove and is fixedly connected to the air bag and is used to abut against the door seal of the steam-bake cooking machine;

[0009] When the door of the steam-bake cooking machine is opened, the air bag expands to generate negative pressure, so that the overflowing steam is sucked into the air bag from the first air hole.

[0010] With such arrangement, a negative pressure zone can be formed at the first air hole at the moment the door is opened, thereby relieving the impact force of the steam and preventing the steam from rushing directly to the handle end, thereby preventing the user's palms and arms from being scalded by the steam.

[0011] In one embodiment, the airbag includes a telescopic tube provided with the first air hole and a first mounting plate and a second mounting plate sealed at both end openings of the telescopic tube, the first mounting plate is fixedly connected to the door body, and the second mounting plate is fixedly connected to the inner plate.

[0012] With this arrangement, due to the inertia of the inner panel itself, the inner panel will not rotate synchronously with the door body at the moment of opening the door, but will briefly stay at the door seal. The telescopic tube is thus stretched to form a negative pressure in the airbag, and the faster the door opens, the more obvious the negative pressure.

[0013] In one embodiment, the telescopic tube is an elastic member and the natural length of the telescopic tube is greater than the depth of the accommodating groove.

[0014] With such a configuration, the receiving groove can also be used to absorb steam, and the diffusion of steam from both sides of the door assembly can be reduced at the moment of opening the door, which is beneficial to reducing the risk of steam scalding the user.

[0015] In one embodiment, a side of the inner plate close to the rotating end is rotatably mounted on the door body.

[0016] Such an arrangement connects the inner panel to the door body and limits the rotation direction of the inner panel, thereby reducing the supporting pressure of the airbag on the inner panel and preventing the airbag from being damaged by shear deformation.

[0017] In one embodiment, the door assembly also includes a return spring installed between the door body and the inner panel, one end of the return spring is fixed to the door assembly, and the other end is drivingly connected to the inner panel to drive the side of the inner panel close to the handle end to rotate toward the door body to compress the airbag.

[0018] With such arrangement, due to the support of the rotating shaft and the limitation of the torsion spring, the inner plate will not rotate at a large angle, thus ensuring that the telescopic tube will not be damaged due to the large inertia force of the inner plate during the door opening process; at the same time, when the steam-bake cooking machine is in the door-open state, the torsion spring can also assist in discharging the gas in the airbag, thereby reducing the obstruction of the airbag when closing the door again.

[0019] In one embodiment, the door body includes a door frame and an outer plate mounted on the door frame to enclose the receiving groove, the door frame has an air flow channel and an air inlet and an air outlet connected to the air flow channel, the air bag is further provided with a second air hole connected to the air inlet, and the air outlet is located on a side of the door frame away from the handle end;

[0020] Therefore, the door assembly also includes a fan assembly installed in the air flow channel.

[0021] With such an arrangement, driven by the fan assembly, air is drawn from the airbag into the air flow channel, and finally discharged from the air outlet facing away from the handle end, further reducing the risk of burns to the user.

[0022] In one embodiment, the size of the second pore is larger than the size of the first pore.

[0023] Such an arrangement makes it easier for gas to be discharged from the second air hole, thereby helping to reduce the working pressure of the fan assembly.

[0024] In one embodiment, the door frame includes a left frame column, an upper frame beam and a right frame column connected in sequence, the air inlet is located on a side of the upper frame beam facing the receiving groove, and the number of the air outlets is multiple and they are respectively located on a side of the left frame column away from the right frame column and a side of the right frame column away from the left frame column;

[0025] The fan assembly includes a pair of cross-flow fans respectively mounted on the left frame column and the right frame column.

[0026] Such an arrangement forms a symmetrical air duct, thereby enhancing the negative pressure of the door assembly at the first air hole.

[0027] In one of the embodiments, a plurality of air suction ports are provided on a side of the upper frame beam facing the door seal.

[0028] With such an arrangement, under the negative pressure of the fan assembly, the air suction port continuously draws the escaping steam at the handle end into the air flow channel, further reducing the risk of scalding the user.

[0029] The present application also provides a steaming and baking cooking machine, comprising:

[0030] An inner liner assembly, comprising an inner liner body having an opening and a door seal installed at the opening of the inner liner body; and

[0031] A door assembly, wherein the door body of the door assembly is rotatably mounted on the inner tank body, and the inner plate of the door assembly is used to abut against the door seal.

[0032] Such a setting is adapted to the use scenario of quickly opening the door of the steam-bake cooking machine. By using the door assembly provided by the present application, the handle end of the door assembly generates a negative pressure zone with the help of the airbag at the moment of opening the door, thereby preventing steam from directly rushing to the user's palms and arms, and reducing the risk of the user being scalded by steam.

[0050] Existing steam-bake cooking machines use a door sealing ring and a glass sealing structure inside the door body. When the steam function is working, the steam generated is sealed in the inner pot cavity by the door sealing ring made of silicone. When the inner pot is full of steam, such as in normal working state or just after finishing work, when the door body is opened, a large amount of steam will be ejected through the gap between the door body and the inner pot. At this time, the steam pressure is too high, causing a large amount of steam to flow toward the user.

[0051] Steam flowing toward the user's face may cause burns to the palm or arm when opening the door. When using the steam function, the user cannot guarantee that the door is opened quickly every time to avoid the gushing steam. In addition, some users will open the door at a small angle to prevent the steam in the inner pot from blowing in their face when opening the door. This action releases the steam in the inner pot in advance, but this action is more likely to cause burns to the palm. Therefore, for users, when opening the door, they should open it as quickly as possible and keep their palms and arms away from the steam blowing in their face.

[0052] Based on this, it is necessary to provide a door assembly and a steam-bake cooking machine that can prevent the palms and arms of the user from being scalded by steam.

[0053] See also Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of a door assembly in an embodiment provided in the present application. Figure 2 for Figure 1A partial structural schematic diagram of the door assembly is shown in . The steam-bake cooking machine provided in the present application includes a door assembly and an inner pot assembly. The inner pot assembly includes an inner pot body with an opening and a door seal installed on the opening of the inner pot body. The door assembly is rotatably installed on the inner pot body and abuts against the door seal. The door assembly includes a door body 10, an air bag 20 and an inner plate 30. The door body 10 has a handle end 102 and a rotating end 101 that are far away from each other. The door body 10 is also provided with a receiving groove 103 between the rotating end 101 and the handle end 102. The air bag 20 is installed in the receiving groove 103. A first air hole 201 is provided on the side of the air bag 20 close to the handle end 102. The inner plate 30 is provided at the notch of the receiving groove 103 and is fixedly connected to the air bag 20 and is used to abut against the door seal of the steam-bake cooking machine. When the door of the steam-bake cooking machine is opened, the airbag 20 expands to generate negative pressure, so that the overflowing steam is sucked into the airbag 20 from the first air hole 201. In other words, a negative pressure area can be formed at the first air hole 201 at the moment the door is opened, which relieves the impact force of the steam and prevents the steam from rushing directly to the handle end 102, thereby preventing the user's palms and arms from being scalded by the steam.

[0054] See also Figure 1 , Figure 2 and Figure 3 , Figure 3 for Figure 2Schematic diagram of the structure of the airbag 20. Specifically, the airbag 20 includes a telescopic cylinder 21, a first mounting plate 22 and a second mounting plate 23. The first mounting plate 22 and the second mounting plate 23 are respectively sealed at the two end openings of the telescopic cylinder 21. The first mounting plate 22 is fixedly connected to the door body 10, and the second mounting plate 23 is fixedly connected to the inner plate 30. The first air hole 201 is located in the telescopic cylinder 21. Due to the inertia of the inner plate 30 itself, the inner plate 30 will not rotate synchronously with the door body 10 at the moment of opening the door, but will stay at the door seal for a short time. The telescopic cylinder 21 is thus stretched to form a negative pressure in the airbag 20. It can be understood that the faster the door body 10 rotates when opening the door and the heavier the inner plate 30, the greater the instantaneous negative pressure in the airbag 20, and the stronger the ability to absorb steam. Therefore, it meets the actual use scenario of users opening the door quickly. Optionally, the telescopic cylinder 21 adopts an elastic bellows. Preferably, the natural length of the telescopic cylinder 21 is greater than the depth of the receiving groove 103. When the steam-bake cooking machine is in a closed state, the elastic bellows is compressed. After such a configuration, at the moment of opening the door, the inner plate 30 can still abut the door seal, and negative pressure has been generated in the airbag 20, that is, the negative pressure area at the first air hole 201 is generated before the steam is ejected, so that the steam can be prevented from rushing to the user as much as possible; in addition, this can also assist the user to open the door, without the user opening the door body to a smaller angle in advance to release the pressure, further avoiding the pressure relief action causing the user to be scalded. Optionally, in an embodiment provided in the present application, the size of the airbag 20 is smaller than the size of the receiving groove 103, and the size of the inner plate 30 is smaller than the notch size of the receiving groove 103 so as to be suspended from the receiving groove 103. In this way, the receiving groove 103 can also be used to absorb steam, and at the moment of opening the door, the diffusion of steam from both sides of the door assembly can be reduced, which is conducive to reducing the risk of steam scalding the user.

[0055] See also Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 8 , Figure 4 for Figure 2 A schematic diagram of the structure of the middle door body 10, Figure 5 for Figure 2 A schematic diagram of the structure of the middle inner plate 30 from another perspective, Figure 6 2 is a cross-sectional view of the door assembly, Figure 8 for Figure 6A partial enlarged view at Y in the figure. Optionally, in one embodiment provided in the present application, one side of the inner panel 30 close to the rotating end 101 is rotatably mounted on the door body 10. By connecting the inner panel 30 to the door body 10 and limiting the rotation direction of the inner panel 30, the supporting pressure of the airbag 20 on the inner panel 30 is reduced, thereby preventing the airbag 20 from being shear deformed and damaged. Furthermore, the door assembly also includes a return spring 40 installed between the door body 10 and the inner panel 30, one end of the return spring 40 is fixed to the door assembly, and the other end is drivingly connected to the inner panel 30 to drive the side of the inner panel 30 close to the handle end 102 to rotate toward the door body 10 to compress the airbag 20. Optionally, in an embodiment provided in the present application, the return spring 40 is a torsion spring, the door body 10 also includes a rotating shaft 13 located in the accommodating groove 103, the inner plate 30 includes a plate body 31 and a connecting seat 32 installed on the plate body 31 and rotatably installed on the rotating shaft 13, the torsion spring is sleeved on the rotating shaft 13 and the two ends of the torsion spring are respectively abutted against the bottom of the accommodating groove 103 and the lower end of the inner plate 30, due to the support of the rotating shaft 13 and the limitation of the torsion spring, the inner plate 30 will not rotate a large angle, and during the door opening process, it can ensure that the telescopic cylinder 21 will not be damaged due to the large inertia force of the inner plate 30; at the same time, when the steam-bake cooking machine is in the door-open state, the torsion spring can also assist in discharging the gas in the airbag 20, which can reduce the obstruction of the airbag 20 when the door is closed again.

[0056] See also Figure 4 , Figure 6 and Figure 7 , Figure 6 2 is a cross-sectional view of the door assembly, Figure 7 for Figure 6Specifically, the door body 10 includes a door frame 11, an outer plate 12, an upper cover 14 and a cover plate 15. The outer plate 12 is installed on the door frame 11 to enclose a receiving groove 103. The upper cover 14 is located above the door frame 11 and encloses a mounting groove for accommodating a circuit board with the door frame 11. The cover plate 15 is covered on the door frame 11 and the upper cover 14, and a through hole with the same shape as the inner plate 30 is opened in the middle of the cover plate 15. The door frame 11 also has an air flow channel 104 and an air inlet 1101 and an air outlet 1101 connected to the air flow channel 104. 102, the air inlet 1101 is formed by the upper frame beam 111 being concave and opening on one side of the outer plate 12, the air bag 20 is also provided with a second air hole 202 connected to the air inlet 1101, and a physical structure on the air bag 20 for providing the second air hole 202 is inserted into the air inlet 1101 to connect the second air hole 202 with the air inlet 1101, the air outlet 1102 is located on the side of the door frame 11 away from the handle end 102, and the door assembly also includes a fan assembly 50 installed in the air flow channel 104. Driven by the fan assembly 50, the air flow is drawn from the air bag 20 into the air flow channel 104, and finally discharged from the air outlet away from the handle end 102, further reducing the risk of burns to the user. It is worth noting that due to the negative pressure generated by the fan assembly 50 at the air inlet 1101, when the door panel compresses the airbag 20 under the action of the return spring 40, the gas in the airbag 20 is discharged from the second air hole 202 first. The power of the fan assembly 50 is set to achieve no gas discharge from the first air hole 201, and the airflow in the airbag 20 is unidirectional, avoiding the risk of users being scalded by exhaust from the first air hole 201 of the airbag 20 after the door assembly is opened. Furthermore, in an embodiment provided in the present application, the size of the second air hole 202 is larger than the size of the first air hole 201, which is more convenient for gas to be discharged from the second air hole 202, thereby helping to reduce the working pressure of the fan assembly 50. It is worth noting that the opening time of the fan assembly 50 is before opening the door or during the stretching process of the telescopic sleeve, so as to ensure that the door assembly has a stable negative pressure at the first air hole 201. Optionally, in order to prevent backflow in the airflow channel 104 , one-way air valves are installed at both ends of the upper frame beam 111 , and the passing direction of the one-way air valve is from the upper frame beam 111 toward the left frame column 112 or the right frame column 113 .

[0057] See also Figure 4Specifically, the door frame 11 includes a left frame column 112, an upper frame beam 111 and a right frame column 113 which are connected in sequence, an air inlet 1101 is located on the side of the upper frame beam 111 facing the receiving groove 103, a plurality of air outlets 1102 are respectively located on the side of the left frame column 112 away from the right frame column 113 and the side of the right frame column 113 away from the left frame column 112, and a fan assembly 50 includes a pair of cross-flow fans 51 respectively installed on the left frame column 112 and the right frame column 113. In this way, a symmetrical air duct is formed, which enhances the negative pressure of the door assembly at the first air hole 201.

[0058] See also Fig. 9 , Fig. 9 This is a schematic diagram of the structure of the door body 10 in another embodiment provided in the present application. Optionally, in an embodiment provided in the present application, a plurality of air suction ports 1103 are further provided on the side of the upper frame beam 111 facing the door seal. Under the negative pressure of the fan assembly 50, the air suction ports 1103 continuously suck the escaping steam at the handle end 102 into the air flow channel 104, further reducing the risk of scalding the user. Furthermore, there are multiple air suction ports 1103 and the size of the air suction ports 1103 gradually decreases from the middle of the upper frame beam 111 toward both sides, so that the door assembly absorbs more escaping steam near the door handle, which helps to reduce the amount of escaping steam rushing towards the user.

[0059] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
