Description

Technical Field

[0001] The invention relates to the field of household appliances, and in particular to a door structure and a cooking utensil. Background Art

[0002] Cooking equipment, such as a stove-steam-bake combination machine, is a device that integrates cooking devices such as an oven, a steamer, and a gas stove to reduce space occupation and diversify functions. Generally, this type of cooking equipment includes a box with a cooking space and a door body connected to the box body that can be opened and closed. When cooking, the door body is closed to form a closed cooking space to heat the ingredients in the cooking space.

[0003] When the cooking time is long, the temperature in the cooking space will cause the temperature on the door body to gradually rise, and there is a risk of scalding the user when the user touches the door body. Summary of the invention

[0004] In view of this, it is necessary to provide a door structure and a cooking utensil to address the above problems so as to prevent users from being scalded when touching the door.

[0005] The present invention first provides a door body structure for use in a cooking appliance, comprising: a door body, the door body comprising a door frame assembly, an outer door panel, a middle door panel and an inner door panel, the door frame assembly stacks the outer door panel, the middle door panel and the inner door panel in sequence, and a heat insulating space is formed between the middle door panel and the inner door panel, a heat dissipation space is formed between the outer door panel and the middle door panel, and an air port for connecting the outside with the heat dissipation space is provided on the door frame assembly; and a heat dissipation assembly, comprising two heat dissipation groups located in the heat dissipation space, each of the heat dissipation groups comprising a first fan and an air guide plate connected to an outlet of the first fan, the two air guide plates are respectively arranged at the top and bottom of the heat dissipation space, the air outlets of the two air guide plates are staggered along the width direction of the door body, and the air outlet of the air guide plate located at the top of the heat dissipation space is opened toward the bottom of the heat dissipation space, and the air outlet of the air guide plate located at the bottom of the heat dissipation space is opened toward the top of the heat dissipation space.

[0006] In the above-mentioned door body structure, when the first fans of the two heat dissipation groups are working, they can introduce the external low-temperature air into the two first fans and the two air guide plates through the air ports respectively. Since the air outlets of the two air guide plates are staggered along the width direction of the door body, the wind blown out from the air outlets of the two air guide plates is also staggered along the width direction of the door body, basically without interfering with each other, so as to expand the flow area of ​​the wind in the heat dissipation space, and by setting up two first fans and two air guide plates, the flow rate of the wind blown out from the air outlet of each air guide plate can also be guaranteed to uniformly dissipate the heat of the heat dissipation space and the outer door panel; thereby, the heat dissipation effect on the heat dissipation space and the outer door panel can be improved, the temperature of the outer door panel can be reduced, and the user can avoid being scalded when touching the outer door panel. At the same time, arranging the heat dissipation component in the heat dissipation space can also avoid lowering the temperature of the insulation space and the inner door panel, and avoid affecting the cooking effect in the cooking space.

[0007] In one embodiment, the wind guide plate is stepped, and along the flow direction of wind on the wind guide plate, the wind guide area of ​​each stepped section of the wind guide plate gradually decreases; or along the flow direction of wind on the wind guide plate, the wind guide area of ​​the wind guide plate gradually decreases.

[0008] Such an arrangement gradually increases the velocity of the wind in the air guide plate, thereby ensuring that the wind in the air guide plate can flow evenly from the air outlet of the air guide plate to the heat dissipation space, ensuring uniform heat dissipation of the heat dissipation space and the outer door panel.

[0009] In one of the embodiments, the heat dissipation assembly further includes a second fan disposed at the bottom end of the heat dissipation space, an air outlet of the second fan is opened toward the top end of the heat dissipation space, and the second fan is located between the two air guide plates.

[0010] With such an arrangement, the wind flow rate blown out from the second fan is faster, thereby being able to avoid turbulence, and the second fan can also improve the heat dissipation effect on the heat dissipation space and the outer door panel.

[0011] In one of the embodiments, the heat dissipation assembly further includes an air guide member disposed at an air outlet of the second fan, and an air guide area of ​​the air guide member decreases along a flow direction of wind in the air guide member.

[0012] Such an arrangement can increase the flow rate of the wind blown out from the second fan and the wind guide, thereby improving the heat dissipation effect on the heat dissipation space.

[0013] In one embodiment, the air guide is conical.

[0014] With such arrangement, the air guide member has a simple structure and is easy to produce and process.

[0015] In one embodiment, the air guide plate located at the bottom end of the heat dissipation space is a first air guide plate, the first air guide plate has a first air outlet and a second air outlet connected to the first air outlet, the wind direction of the first air outlet is set toward the top end of the heat dissipation space, and the second air outlet is connected to the air inlet of the second fan.

[0016] With this arrangement, the first fan and the first air guide plate can introduce lower temperature wind to the second fan, which is beneficial to the heat dissipation of the second fan, and can also improve the heat dissipation effect of the wind blown out from the second fan on the heat dissipation space and the outer door panel.

[0017] In one of the embodiments, the door frame assembly is provided with an air inlet connected to the air inlet of the second fan.

[0018] With such arrangement, when the second fan is working, the outside low-temperature air can be introduced into the second fan through the air inlet, which is also beneficial to the heat dissipation of the second fan, and can also improve the heat dissipation effect of the wind blown out from the second fan on the heat dissipation space and the outer door panel.

[0019] In one embodiment, the door frame assembly includes a first frame and a second frame, the second frame is located in the first frame, the outer door panel and the inner door panel are connected through the first frame, one side of the middle door panel is connected to the second frame, and the other sides are connected to the first frame, the second frame, the first frame, the inner door panel and the outer door panel form an assembly cavity, the first fan is located in the assembly cavity, and the air guide plate is located in the heat dissipation space.

[0020] With such an arrangement, the first fan can be installed by utilizing the larger distance between the outer door panel and the inner door panel, thereby avoiding increasing the distance between the outer door panel and the middle door panel and causing an increase in the overall thickness of the door body.

[0021] In one of the embodiments, the outer door panel includes a window area, the window area is opposite to the heat dissipation space, and the projection of the middle door panel on the outer door panel is larger than the window area.

[0022] Such an arrangement ensures that there is sufficient space outside the window area for installing structures such as the first air guide plate, the second air guide plate, the second fan, and the air guide member. When the user observes the cooking situation inside the cooking space through the window area, the user will not see the first air guide plate, the second air guide plate, the second fan, and the air guide member, thereby avoiding affecting the user's field of vision.

[0023] In one of the embodiments, a dustproof plate is further included, and the dustproof plate is located in the heat dissipation space and below the air port.

[0024] With such an arrangement, the dustproof plate can prevent impurities, stains, water stains, etc. that fall from the air outlet from falling down into the heat dissipation space, thereby avoiding affecting the user's observation of the cooking situation inside the cooking space.

[0025] The invention also provides a cooking utensil, comprising the door structure. BRIEF DESCRIPTION OF THE DRAWINGS

The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more of the related listed items.

[0039] Cooking equipment, such as a stove-steam-bake machine, is a device that integrates cooking devices such as an oven, a steamer, and a gas stove to reduce space occupation and diversify functions. Usually, this type of cooking equipment includes a box with a cooking space and a door body connected to the box body that can be opened and closed. When cooking, the door body is closed to form a closed cooking space to heat the ingredients in the cooking space. When the cooking time is long, the temperature in the cooking space will cause the temperature on the door body to gradually rise. When the user touches the door body, there is a risk of scalding the user.

[0040] In order to solve the above problems, Figures 1 to 9 As shown, the present invention provides a door structure and a cooking utensil to prevent users from being scalded when touching the door.

[0041] like Figure 1 As shown, the door structure is used in a cooking appliance. The cooking appliance includes a box body 40 and a door structure. The box body 40 includes a cooking space. The door structure can be movably connected to the box body 40 to open or close the cooking space.

[0042] like Figures 2 to 5As shown, specifically, the door structure includes a door body 10 and a heat dissipation assembly 20, wherein: the door body 10 includes a door frame assembly 11, an outer door panel 12, a middle door panel 13 and an inner door panel 14, the door frame assembly 11 stacks the outer door panel 12, the middle door panel 13 and the inner door panel 14 in sequence, and forms a heat insulation space 15 between the middle door panel 13 and the inner door panel 14, and forms a heat dissipation space 16 between the outer door panel 12 and the middle door panel 13, and an air port 111 is provided on the door frame assembly 11 to connect the outside with the heat dissipation space 16; the heat dissipation assembly 20 includes a heat dissipation space 16 located in the heat dissipation space 16 There are two heat dissipation groups 21 inside, each heat dissipation group 21 includes a first fan 211 and an air guide plate 212 connected to the outlet of the first fan 211, the two air guide plates 212 are respectively arranged at the top and bottom ends of the heat dissipation space 16, the air outlets of the two air guide plates 212 are staggered along the width direction of the door body 10, that is, the X-axis direction shown in the figure, and the air outlet of the air guide plate 212 located at the top of the heat dissipation space 16 is opened toward the bottom end of the heat dissipation space 16, and the air outlet of the air guide plate 212 located at the bottom end of the heat dissipation space 16 is opened toward the top of the heat dissipation space 16.

[0043] The air guide plate 212 at the bottom of the heat dissipation space 16 is defined as a first air guide plate 2121, and the air guide plate 212 at the top of the heat dissipation space 16 is defined as a second air guide plate 2122. When the door structure closes the cooking space, the inner door panel 14 is located on the side of the middle door panel 13 facing the cooking space, and the outer door panel 12 is located on the side of the middle door panel 13 facing away from the cooking space.

[0044] In the door structure provided by the embodiment of the present invention, when the first fans 211 of the two heat dissipation groups 21 are working, the low-temperature air from the outside can be introduced into the two first fans 211 and the two air guide plates 212 through the air port 111 respectively, and the wind blown out from the air outlet of the first air guide plate 2121 flows toward the top of the heat dissipation space 16, and the wind blown out from the air outlet of the second air guide plate 2122 flows toward the bottom of the heat dissipation space 16, and the wind in the heat dissipation space 16 can also be discharged from the door structure through the air port 111; because the air outlets of the two air guide plates 212 are staggered along the width direction of the door 10, the wind blown out from the air outlets of the two air guide plates 212 also flows along the width direction of the door 10. The door body 10 is staggered in the width direction and basically does not interfere with each other, so as to expand the flow area of ​​wind in the heat dissipation space 16, and by providing two first fans 211 and two air guide plates 212, the flow rate of the wind blown out from the air outlet of each air guide plate 212 can be guaranteed to uniformly dissipate heat to the heat dissipation space 16 and the outer door panel 12; thereby, the heat dissipation effect on the heat dissipation space 16 and the outer door panel 12 can be improved, the temperature of the outer door panel 12 can be reduced, and the user can avoid being scalded when touching the outer door panel 12. At the same time, arranging the heat dissipation component 20 in the heat dissipation space 16 can also avoid lowering the temperature of the insulation space 15 and the inner door panel 14, and avoid affecting the cooking effect in the cooking space.

[0045] like Figures 8 to 9 As shown, along the flow direction of the wind on the wind guide plate 212, the wind guide area of ​​the wind guide plate 212 gradually decreases. Since the wind volume in the wind guide plate 212 will gradually decrease along the flow direction of the wind on the wind guide plate 212, the wind guide plate 212 is set to gradually reduce the wind guide area, so that the flow rate of the wind in the wind guide plate 212 gradually increases, thereby ensuring that the wind in the wind guide plate 212 can flow evenly from the air outlet of the wind guide plate 212 to the heat dissipation space 16, ensuring the uniformity of heat dissipation of the heat dissipation space 16 and the outer door panel 12.

[0046] In one embodiment, the air guide plate 212 is stepped, and along the flow direction of the wind on the air guide plate 212, the air guide area of ​​each section of the stepped air guide plate 212 gradually decreases. The structure of the air guide plate 212 is simple and easy to process. Of course, in other embodiments, along the flow direction of the wind on the air guide plate 212, the side surface of the air guide plate 212 opposite to the air outlet is set to be a surface that gradually tilts toward the air outlet, and the surface can be a plane or a curved surface, and the embodiment of the present invention does not make specific restrictions here.

[0047] like Figures 5 to 7 As shown, since the wind blown out from the air outlet of the air guide plate 212 will diffuse to the surroundings, and the flow directions of the wind blown out from the air outlet of the first air guide plate 2121 and the air outlet of the second air guide plate 2122 are opposite, turbulence may occur at the junction of the wind blown out from the first air guide plate 2121 and the wind blown out from the second air guide plate 2122, affecting the heat dissipation effect of the heat dissipation space 16. Therefore, the heat dissipation component 20 also includes a second fan 22 arranged at the bottom end of the heat dissipation space 16, the air outlet of the second fan 22 is opened toward the top end of the heat dissipation space 16, and the second fan 22 is located between the two air guide plates 212. It should be noted that the second fan 22 is located between the two air guide plates 212, which means that there is a gap between the projections of the first air guide plate 2121 and the second air guide plate 2122 on the bottom end of the heat dissipation space 16, and the second fan 22 is arranged in the gap. The wind blown out by the second fan 22 flows toward the top of the heat dissipation space 16 . Since the wind blown out from the second fan 22 has a faster flow rate, turbulence can be avoided. The second fan 22 can also improve the heat dissipation effect on the heat dissipation space 16 and the outer door panel 12 .

[0048] Furthermore, since the temperature of the central area of ​​the heat dissipation space 16 is usually high and difficult to dissipate heat, it is preferred that the second fan 22 is disposed at the center of the bottom end of the heat dissipation space 16 to improve the heat dissipation effect of the central area of ​​the heat dissipation space 16. The first air guide plate 2121 and the second air guide plate 2122 are located on both sides of the second fan 22, respectively.

[0049] like Figure 5 and Figure 7As shown, the heat dissipation assembly 20 further includes an air guide 23 disposed at the air outlet of the second fan 22, and the air guide area of ​​the air guide 23 is reduced along the flow direction of the wind in the air guide 23. In this way, the flow rate of the wind blown out from the second fan 22 and the air guide 23 can be further increased, and the heat dissipation effect on the central area of ​​the heat dissipation space 16 can be improved.

[0050] In one embodiment, the air guide 23 is conical. The structure of the air guide 23 is simple and easy to produce and process. Of course, in other embodiments, the inner wall of the air guide 23 may also be stepped, inclined, curved, or other structures, as long as the air guide area of ​​the air guide 23 is gradually reduced along the flow direction of the wind in the air guide 23, and the embodiment of the present invention does not make specific restrictions here.

[0051] like Figure 8 As shown, since the second fan 22 is arranged at the bottom center of the heat dissipation space 16, the ambient temperature is relatively high. Therefore, the first air guide plate 2121 has a first air outlet 21211 and a second air outlet 21212 connected to the first air outlet 21211. The wind direction of the first air outlet 21211 is arranged toward the top of the heat dissipation space 16, and the second air outlet 21212 is connected to the air inlet of the second fan 22. Part of the wind in the first air guide plate 2121 flows from the first air outlet 21211 toward the top of the heat dissipation space 16, and the remaining part of the wind flows from the second air outlet 21212 to the air inlet of the second fan 22, and flows toward the top of the heat dissipation space 16 through the air outlet of the second fan 22 and the air guide 23. The first fan 211 and the first air guide plate 2121 can introduce wind with a lower temperature to the second fan 22, which is beneficial to the heat dissipation of the second fan 22, and can also improve the heat dissipation effect of the wind blown out from the second fan 22 on the heat dissipation space 16 and the outer door panel 12.

[0052] like Figure 6 As shown, the door frame assembly 11 is provided with an air inlet 112 connected to the air inlet of the second fan 22. When the second fan 22 is working, the low-temperature air from the outside can be introduced into the second fan 22 through the air inlet 112, which is also beneficial to the heat dissipation of the second fan 22, and can also improve the heat dissipation effect of the wind blown out from the second fan 22 on the heat dissipation space 16 and the outer door panel 12. When the second air outlet 21212 and the air inlet 112 are provided at the same time, the air volume introduced into the second fan 22 can be increased, thereby increasing the air volume blown out from the second fan 22 and the air guide 23, and improving the heat dissipation effect on the central area of ​​the heat dissipation space 16.

[0053] like Figures 4 to 5 As shown, in one embodiment, along the width direction of the door body 10, the two first fans 211 are arranged on the same side of the door body 10 to avoid occupying too much space inside the door body 10 and ensure that there is enough area for the user to observe the cooking situation in the cooking space through the door body 10. Fig. 9 As shown, specifically, the second air guide plate 2122 includes an extension section 21221 and an air outlet section 21222, the two ends of the extension section 21221 are respectively connected to the first fan 211 and the air outlet section 21222, the air outlet section 21222 is provided with a third air outlet 21223 facing the bottom end of the heat dissipation space 16, and the third air outlet 21223 and the first air outlet 21211 are staggered along the width direction of the door body 10. Of course, in other embodiments, along the width direction of the door body 10, the two first fans 211 can also be respectively provided on both sides of the door body 10.

[0054] The heat dissipation group 21 may further include an air outlet grid disposed at the first air outlet 21211 or the third air outlet 21223 , so that the wind blown into the heat dissipation space 16 from the first air outlet 21211 and the third air outlet 21223 is more uniform.

[0055] like Figures 2 to 3 As shown, due to the limited spacing between the outer door panel 12 and the middle door panel 13, it is difficult to install the first fan 211. Therefore, the door frame assembly 11 includes a first frame 113 and a second frame 114, the second frame 114 is located in the first frame 113, the outer door panel 12 and the inner door panel 14 are connected through the first frame 113, one of the sides of the middle door panel 13 is connected to the second frame 114, and the other sides are connected to the first frame 113, the second frame 114, the first frame 113, the inner door panel 14 and the outer door panel 12 form an assembly cavity 17, the first fan 211 is located in the assembly cavity 17, and the air guide plate 212 is located in the heat dissipation space 16. Therefore, the first fan 211 can be installed by reducing the area of ​​the middle door panel 13 and utilizing the larger spacing between the outer door panel 12 and the inner door panel 14, thereby avoiding increasing the spacing between the outer door panel 12 and the middle door panel 13, which leads to an increase in the overall thickness of the door body 10. The second frame 114 is used to support the middle door plate 13, ensure the stability and reliability of the middle door plate 13, and also can isolate the heat dissipation space 16 and the assembly cavity 17, reduce the temperature in the assembly cavity 17, and thus reduce the temperature of the wind introduced into the first fan 211. In addition, the assembly cavity 17 can be located on a side of the box body 40 close to the water tank, so as to further reduce the temperature in the assembly cavity 17, and thus further reduce the temperature of the wind introduced into the first fan 211.

[0056] like Figures 4 to 5As shown, the outer door panel 12 includes a window area a, the window area a is opposite to the heat dissipation space 16, and the projection of the middle door panel 13 on the outer door panel 12 is larger than the window area a. The user can observe the cooking situation inside the cooking space through the window area a. In this way, there is enough space outside the window area a to install the first air guide plate 2121, the second air guide plate 2122, the second fan 22, the air guide member 23 and other structures. When the user observes the cooking situation inside the cooking space through the window area a, the first air guide plate 2121, the second air guide plate 2122, the second fan 22, the air guide member 23 and other structures will not be seen, so as to avoid affecting the user's field of vision.

[0057] like Figure 5 and Figure 7 As shown, the door structure also includes a dustproof plate 30, which is located in the heat dissipation space 16 and below the air port 111. The dustproof plate 30 can prevent impurities, stains, water stains, etc. that fall from the air port 111 from falling down into the heat dissipation space 16, so as to avoid affecting the user's observation of the cooking situation inside the cooking space through the window area a. Specifically, the dustproof plate 30 can be set separately or on the second air guide plate 2122, as long as the dustproof plate 30 can cover the air port 111 and will not affect the normal air inlet and outlet of the air port 111, the embodiment of the present invention is not specifically limited here.

[0058] like Figure 1 As shown, the embodiment of the present invention further provides a cooking appliance, comprising the above-mentioned door structure. The cooking appliance further comprises a box 40, the box 40 comprises a cooking space, and the door structure can be movably connected to the box 40 to open or close the cooking space.

[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. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
