Description

Technical Field

[0001] The invention relates to the technical field of kitchen appliances, in particular to a steam oven door and a steam oven. Background Art

[0002] As people's living standards improve, kitchen appliances are becoming more and more intelligent, and steam ovens with multiple functions are becoming more and more popular among users. Steam ovens generally include a cabinet, an inner tank, a water tank and a steam generator. When steam cooking is performed, steam is generated by heating the steam generator, and then the steam is passed into the inner tank to use the steam to steam and cook the food. After the steam oven is equipped with a baking function, the baking component is used to bake the food in the inner tank. The introduction of the baking function increases the temperature in the inner tank, causing the glass cabinet door to have a certain temperature under heat transfer, which can easily scald the user.

[0003] In the prior art, an exhaust vent is usually set at the top of the door frame structure of the oven. During the operation of the oven, the heat inside the cavity gradually increases the temperature of the door body through heat radiation. At this time, the heat in the interlayer of the door body gradually increases and is discharged through the exhaust vent on the top. As the oven continues to work, the temperature of the interlayer of the door body will become higher and higher. Simply relying on the exhaust vent to dissipate heat cannot reduce the temperature of the door body in a short time. If the temperature of the door body is too high, the user can feel the heat of the door body, and the experience is poor; when opening the door body, if the inside of the door body is accidentally touched, the user may be scalded.

[0004] Therefore, it is urgent to propose a steam oven door and a steam oven to solve the above problems. Summary of the invention

[0018] A steam oven, characterized in that the steam oven comprises the above-mentioned steam oven door body and cabinet body, and the steam oven door body and cabinet body are connected.

[0019] Beneficial effects:

[0020] The steam oven door provided by the present invention is surrounded by an outer door panel, an inner door panel and two side door frames to form an air outlet channel, and the heat generated during steaming and baking can flow out through the air outlet channel. Since the air outlet channel is in a trumpet shape with a cross-sectional area at the air outlet end being smaller than that at the air inlet end, when the hot air flows from bottom to top, the cross-sectional area it passes through gradually decreases, and the wind speed increases the further it flows upward, thereby accelerating the outflow of heat, avoiding a poor user experience caused by an overly high temperature of the steam oven door, and reducing the potential risk of scalding the user.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0035] The door of a steam oven is usually provided with a channel for hot air to flow out, prevent the door from being overheated, and play a role in heat insulation. However, in the prior art, the door temperature of the steam oven is still too high, and the user is at risk of being scalded, which results in a poor user experience. The door of the steam oven provided in this embodiment can prevent the temperature from being too high and improve the user experience.

[0036] See also Figures 1 to 3 The present embodiment provides a steam oven door body, including a door panel assembly and a side door frame 300. The door panel assembly includes an outer door panel 100 and an inner door panel 200 that are spaced apart. The side door frames 300 are respectively located on both sides of the door panel assembly and are arranged between the outer door panel 100 and the inner door panel 200. The outer door panel 100, the inner door panel 200 and the side door frame 300 are connected to form an air outlet channel 400. The cross-sectional area of ​​an air outlet end 410 of the air outlet channel 400 is smaller than the cross-sectional area of ​​an air inlet end 420 of the air outlet channel 400.

[0037] The steam oven door is surrounded by an outer door panel 100, an inner door panel 200 and two side door frames 300 to form an air outlet channel 400, and the heat generated during the steaming and baking process can flow out through the air outlet channel 400. Since the air outlet channel 400 is in a trumpet shape with a cross-sectional area of ​​the air outlet end 410 being smaller than a cross-sectional area of ​​the air inlet end 420, when the hot air flows from bottom to top, the cross-sectional area it passes through gradually decreases, and the wind speed increases the further it flows upward, thereby accelerating the outflow of heat, avoiding a poor user experience caused by an overly high temperature of the steam oven door, and reducing the potential risk of scalding the user.

[0038] Furthermore, an upper door frame 500 is provided between the outer door panel 100 and the inner door panel 200 . The upper door frame 500 is located at the air outlet end 410 of the air outlet channel 400 . An air flow outlet 510 is provided on the upper door frame 500 . The air outlet 311 is connected to the air outlet channel 400 .

[0039] It can be understood that the mixed airflow flows out from the air outlet 510 after passing through the air outlet channel 400. The upper door frame 500 is generally in the longitudinal direction, and the air outlet 510 includes a plurality of straight-line openings and a plurality of elliptical openings, the plurality of straight-line openings are arranged in two rows along the length direction of the upper door frame 500, and the elliptical openings are arranged at both ends of the upper door frame 500.

[0040] In this embodiment, there are 10 straight-line openings and 2 elliptical openings. In other embodiments, the shape of the airflow outlet 510 is not limited to straight-line and elliptical, and can be circular, square or waist-shaped, etc. The number can be 8, 10, 12 or 14, etc., which can be set according to specific usage needs.

[0041] Furthermore, a clamping member is provided at both ends of the upper door frame 500, the clamping member has a buckle, and a clamping hole is provided on the side door frame 300, and the buckle is provided in cooperation with the clamping hole. After installing the upper door frame 500, the clamping member is pressed on the end of the side door frame 300 and the buckle is clamped in the clamping hole to fix the upper door frame 500. The setting of the clamping member is a common technical means in the art, and will not be described in detail here.

[0042] Furthermore, an air inlet channel is provided on the side door frame 300 , and the air inlet channel has an air inlet 321 and an air outlet 311 .

[0043] Further, the side door frame 300 includes an inner panel 310 and an outer panel 320 which are spaced apart, an air outlet 311 is disposed on the inner panel 310, a shroud 312 is connected to the inner panel 310, and an air inlet 321 of the air inlet passage is disposed on the outer panel 320. External airflow can enter the space between the inner panel 310 and the outer panel 320 through the air inlet 321, and then enter the air outlet passage 400 through the air outlet 311.

[0044] By arranging the inner plate 310 and the outer plate 320 at intervals, more external airflow can enter and achieve heat exchange through the inner plate 310, thereby increasing the cooling effect.

[0045] Further, see Figures 2 to 3 The outer plate 320 is arranged along the vertical direction, and the inner plate 310 is arranged at an angle to the vertical direction. The interval between the two inner plates 310 near the air outlet end 410 is greater than the interval away from the air outlet end 410. The inner plate 310 limits the width of the air outlet channel 400.

[0046] In this embodiment, the outer plate 320 and the inner plate 310 are two non-parallel flat plate structures, because the steam oven door needs to be buckled with the steam oven cabinet, so the outer plate 320 is arranged along the vertical direction, and the opening of the steam oven cabinet can be set to a regular rectangle. Of course, in other embodiments, the outer plate 320 and the inner plate 310 can be set as two parallel flat plate structures, that is, the outer plate 320 and the inner plate 310 are arranged at an angle with the vertical direction.

[0047] Further, see Figure 3 and Figure 4 The outer panel 320 and the inner panel 310 are connected by a connecting plate 330, and the connecting plate 330 is connected to the inner door panel 200. The outer panel 320, the connecting plate 330, the inner panel 310 and the outer door panel 100 form a cavity. The air inlet 321, the cavity and the air outlet 311 are connected in sequence to form an air inlet channel. The external airflow can enter the air outlet channel 400 through the air inlet 321, the cavity and the air outlet 311 in sequence.

[0048] In this embodiment, the outer plate 320, the connecting plate 330, and the inner plate 310 are sequentially connected to form a frame structure with a U-shaped cross-section. Using such a structure as the side door frame 300, it has high structural strength and is not easily deformed. It can be understood that in this embodiment, the connecting plate 330 is a plate-like structure that is wider at the top and narrower at the bottom, so that the cross-sectional area of the air outlet end 410 of the air outlet channel 400 is smaller than the cross-sectional area of the air inlet end 420.

[0049] In this embodiment, the side door frame 300 is connected to the inner door panel 200 through the connecting plate 330. Optionally, the connecting plate 330 and the inner door panel 200 can be bonded using glass glue. Of course, in other embodiments, the outer plate 320 and the inner plate 310 can be directly connected to the inner door panel 200.

[0050] Further, the card holes are provided on the outer plate 320, and the card connectors are partially inserted into the cavity and are engaged with the card holes on the outer plate 320.

[0051] Further, referring to Figure 3 , a plurality of air inlets 321 are provided, and / or a plurality of air outlets 311 are provided.

[0052] Exemplarily, 2, 3, or 4 air inlets 321 are provided, and 1 air outlet 311 is provided; or, 1 air inlet 321 is provided, and 2, 3, or 4 air outlets 311 are provided; or, 2, 3, or 4 air inlets 321 are provided, and 2, 3, or 4 air outlets 311 are provided. The number of air inlets 321 can be the same as or different from the number of air outlets 311.

[0053] In this embodiment, 6 air inlets 321 are provided, and 5 air outlets 311 are provided. Both the air inlets 321 and the air outlets 311 are long strip-shaped. The air inlets 321 are arranged at intervals along the length direction of the outer plate 320, and the air outlets 311 are arranged at intervals along the length direction of the inner plate 310. Providing a plurality of air inlets 321 (air outlets 311) can increase the flow rate of the external air flow and effectively ensure that the door body of the steam oven is in a relatively low temperature state.

[0054] Further, referring to Figure 4 , a first connecting folding edge 313 is provided on the inner plate 310, and the inner plate 310 is connected to the outer door panel 100 through the first connecting folding edge 313.

[0055] Optionally, the first connecting folding edge 313 is perpendicular to the inner plate 310, and the surface of the first connecting folding edge 313 is attached to the outer door panel 100, and glass glue can be used to bond it to the outer door panel 100. The setting of the first connecting folding edge 313 increases the contact area between the side door frame 300 and the outer door panel 100, thus ensuring a firm connection between the side door frame 300 and the outer door panel 100.

[0056] Optionally, in the present embodiment, the first connecting folded edge 313 extends toward the center axis of the door body of the steam oven. In other embodiments, the first connecting folded edge 313 may extend in a direction away from the center axis of the door body of the steam oven.

[0057] Furthermore, a second connecting folded edge 322 is provided on the outer side panel 320 , and the outer side panel 320 is connected to the outer door panel 100 via the second connecting folded edge 322 .

[0058] Optionally, the second connecting fold 322 and the inner side plate 310 are arranged vertically, and the surface of the second connecting fold 322 is attached to the outer door plate 100, and glass glue can be used to bond the outer door plate 100. The arrangement of the second connecting fold 322 increases the contact area between the side door frame 300 and the outer door plate 100, thereby ensuring that the side door frame 300 and the outer door plate 100 are firmly connected.

[0059] Optionally, in the present embodiment, the second connecting folded edge 322 extends toward the center axis of the door body of the steam oven. In other embodiments, the second connecting folded edge 322 may extend in a direction away from the center axis of the door body of the steam oven.

[0060] Further, see Figures 5 and 6 A deflector 312 is provided at the air outlet 311 of the air inlet channel. The interior of the deflector 312 is connected to the air inlet channel, and the opening of the deflector 312 faces the air outlet end 410 of the air outlet channel 400 .

[0061] See also Figure 6 The air guide cover 312 is connected to the inner plate 310. The air guide cover 312 is convexly arranged on the surface of the inner plate 310 and has an arc-shaped surface. When the hot air flow inside the steam oven flows through the air guide cover 312, the speed is accelerated, and at the same time, the external air flow in the air inlet channel is further driven to enter the air outlet channel 400. Since the temperature of the external air flow is lower than the temperature of the hot air flow inside the steam oven, the external air flow entering the air outlet channel 400 can reduce the temperature of the steam oven door.

[0062] That is to say, the air deflector 312 can not only accelerate the flow of the original hot air flow in the air outlet channel 400, but also accelerate the entry of external air flow, and accelerate the mixing of the external air flow and the hot air flow inside the air outlet channel 400. The mixed air flow is discharged from the air outlet end 410 of the air outlet channel 400, so that the temperature of the steam oven door body is maintained at a low state, thereby greatly improving the heat dissipation effect of the steam oven door body.

[0063] Furthermore, this embodiment also provides a steam oven, comprising the steam oven door and cabinet, wherein the steam oven door and cabinet are connected. The connection method between the steam oven door and the steam oven cabinet is a mature prior art in the art and will not be described in detail here.

[0064] Since the steam oven in this embodiment adopts the above-mentioned steam oven door body, during the steaming and baking process, the hot air flow generated by it can flow out through the air outlet channel 400 in the steam oven door body. Since the air outlet channel 400 adopts a structural form with a small cross-sectional area at the air outlet end 410 and a large cross-sectional area at the air inlet end 420, the closer the hot air flow is to the air outlet end 410, the faster the speed is, thereby accelerating the outflow, avoiding the steam oven door body being too high and reducing the user's experience. At the same time, it prevents the user from accidentally touching the steam oven door body and causing burns.

[0065] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here.
