[0003] The double-cavity steam-bake integrated stove is a type of integrated stove. It is equipped with two cavities that can cook at the same time. The double-cavity design makes it have a high cooking efficiency, so it is very popular among users. However, the double-cavity steam-bake integrated stove has a relatively narrow installation space and a relatively dense surrounding structure, which results in a poor external heat dissipation environment.

Especially when the two cavities are working at the same time, the temperature inside the integrated stove rises rapidly, and the temperature rise of many components of the integrated stove is even at a critical value.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0040] The utility model provides an integrated stove, such as Figures 1 to 7 As shown, the integrated stove includes a frame mechanism 100, an air intake fan assembly 200 and a steaming and baking assembly 300. The frame mechanism 100 is a supporting component of the integrated stove. An installation space is formed in the frame mechanism 100. The air intake fan assembly 200 and the steaming and baking assembly 300 are both arranged in the installation space of the frame mechanism 100. The frame mechanism 100 includes a bottom plate 110 suspended above the ground, a cavity is formed below the bottom plate 110, and an air intake hole 111 is provided on the bottom plate 110. External cold air can enter the interior of the integrated stove from below the bottom plate 110 through the air intake hole 111. The air intake fan assembly 200 includes a first fan 210 and an air duct mechanism 220. The first fan 210 is arranged on the bottom plate 110 and located at the air intake hole 111. The air duct mechanism 220 is formed with a first air duct connected to the outlet of the first fan 210 and extending along the first direction. The steam-bake assembly 300 is arranged side by side with the air inlet fan assembly 200 in the second direction, and the steam-bake assembly 300 includes a second fan 310 and a heat dissipation element 320. A second air duct is formed in the steam-bake assembly 300, which is connected to the air outlet 201 of the first air duct and flows through the heat dissipation element 320. The second fan 310 is arranged in the second air duct. In some embodiments, the first direction is the height direction Z of the integrated stove, that is, the up-down direction; the second direction is the width direction Y of the integrated stove, that is, the front-back direction.

[0041] Since the integrated stove is actually installed in a wall with cabinet partitions on the left and right, it is impossible to dissipate heat effectively around it. Therefore, the integrated stove cannot be effectively ventilated at the back and on the left and right sides. The integrated stove provided by the utility model is provided with an air inlet 111 on the bottom plate 110. Under the action of the first fan 210 and the second fan 310, the air inlet 111 is formed on the bottom plate 110. Figure 6 and Figure 7 As shown, cold air outside the frame mechanism 100 can enter the frame mechanism 100 from below the bottom plate 110 through the air inlet 111, and flow to the heat dissipation element 320 through the first air duct and the second air duct, thereby taking away the heat from the heat dissipation element 320 to achieve heat dissipation of the heat dissipation element 320. The heat dissipation method combining the bottom air intake of the frame mechanism 100 and the dual-fan heat dissipation improves the heat dissipation performance of the integrated stove.

[0042] In some embodiments, the integrated stove is a dual-cavity integrated stove, and the steaming and baking assembly 300 includes a first steaming and baking cavity 350 and a second steaming and baking cavity 360 arranged side by side in a third direction, and the first direction, the second direction and the third direction are perpendicular to each other. In some embodiments, the third direction is the length direction X of the integrated stove, that is, the left-right direction.

[0043] Since the double-cavity integrated stove is very different from the single-cavity steaming and baking stove in terms of structural space layout, the double-cavity requires a larger internal space, and the double-cavity occupies the frame mechanism 100. Therefore, the heating fan used to heat the steaming and baking cavity generally adopts a top-mounted design. After the heating fan is installed, the top cannot be wrapped with insulation structures such as insulation cotton. When the steaming and baking cavity is working, the heat inside the cavity will be directly dissipated from the top to the internal space of the integrated stove outside the steaming and baking cavity, resulting in a very high internal temperature, especially when the two cavities are working at the same time. The internal heat will be even higher. The integrated stove provided in the present application improves the heat dissipation performance of the integrated stove by adopting a heat dissipation method combining bottom air intake and double fan heat dissipation of the frame mechanism 100, reduces the temperature inside the integrated stove, and prolongs the service life of various components in the integrated stove. Of course, in addition to the double-cavity integrated stove, the heat dissipation method combining bottom air intake and double fan heat dissipation is also applicable to other types of integrated stoves, which are not listed here one by one.

[0044] Continue to refer to Figure 4 As shown, the frame mechanism 100 includes, in addition to the bottom plate 110, a first side plate 120 and a second side plate 130 that are arranged opposite to each other in the second direction, a back plate 140 that is located at the rear side in the third direction, a front support plate supported on the front side of the bottom plate 110, and support legs supported below the bottom plate 110. The first side plate 120, the second side plate 130, the bottom plate 110, and the back plate 140 are arranged to form a cubic frame mechanism 100 with a top opening and a front opening. The steaming and baking assembly 300 is installed on the frame mechanism 100 through the front opening and can block the front opening. Figure 1 As shown, the integrated stove also includes a stove body 500, which is arranged on the top of the frame mechanism 100 and blocks the top opening of the frame mechanism 100. It should be noted that the specific structure of the stove body 500 is a prior art and will not be described in detail here. Of course, in other embodiments of the utility model, the frame mechanism 100 can also be set to other shapes according to needs, which is not limited here.

[0045] In some embodiments, a plurality of air inlet holes 111 are provided, and the plurality of air inlet holes 111 are arranged in rows and columns on the bottom plate 110, so that the air intake volume can be increased, thereby improving the heat dissipation performance of the integrated stove. Of course, in other embodiments, the plurality of air inlet holes 111 can also be arranged in other shapes on the bottom plate 110, such as radial, ring, etc. In addition, the shape of the air inlet hole 111 can be set to a round hole, a square hole, a waist-shaped hole, an elliptical hole, etc. according to requirements.

[0046] like Figure 8 and Fig. 9 As shown, in some embodiments, the air duct mechanism 220 includes an air duct bottom plate 222 and an air duct cover plate 221 both extending along a first direction, and a first air duct is formed between the air duct cover plate 221 and the air duct bottom plate 222. When the first direction is the height direction of the integrated stove, the first air duct is extended along the height direction of the integrated stove, and under the action of the first fan 210, the cold air entering the first air duct through the air inlet hole 111 flows upward and forms a heat dissipation airflow.

[0047] In some embodiments, the first fan 210 is a cross-flow fan, which has the advantages of energy saving, small size, light weight, low noise and easy maintenance. In some embodiments, the air duct of the cross-flow fan is basically extended along the third direction, and the length direction of the air duct bottom plate 222 and the air duct cover plate 221 is also the third direction. In order to connect the outlet of the cross-flow fan with the first air duct, a mounting frame 230 is provided outside the first fan 210, and one of the air duct bottom plate 222 and the air duct cover plate 221 is fixed on the mounting frame 230, and the other is directly fixed on the bottom plate 110, so that the airflow generated by the cross-flow fan directly enters the first air duct.

[0048] In one embodiment, the air duct cover plate 221 is mounted on the mounting frame 230, and the air duct bottom plate 222 is mounted on the reinforcing beam 112 of the bottom plate 110. The mounting method may be a detachable connection method such as screw connection and snap connection, or a fixed connection method such as welding. Of course, in other embodiments, the air duct bottom plate 222 may be mounted on the mounting frame 230, and the air duct cover plate 221 may be mounted on the reinforcing beam 112 of the bottom plate 110.

[0049] In order to form the air outlet 201 of the first air duct, in some embodiments, the air duct cover plate 221 is covered on the air duct bottom plate 222 along the second direction, and part of the inner wall surface of the air duct bottom plate 222 or the air duct cover plate 221 is exposed to form the air outlet 201. Exemplarily, in the second direction, the air duct bottom plate 222 is arranged between the air duct cover plate 221 and the steaming and baking assembly 300, and the height of the air duct bottom plate 222 is set to be lower than the height of the air duct cover plate 221, so that the air duct bottom plate 222 cannot completely cover the air duct cover plate 221, and the air outlet 201 is formed at the position of the air duct cover plate 221 that is not covered by the air duct bottom plate 222. Of course, the relative positions of the duct bottom plate 222 and the duct cover plate 221 in the second direction can also be adjusted, and the height of the duct bottom plate 222 can be set higher than the height of the duct cover plate 221, so that the duct cover plate 221 cannot completely cover the duct bottom plate 222, and the air outlet 201 is formed at the position of the duct bottom plate 222 that is not covered by the duct cover plate 221. Such a setting avoids the operation of opening holes in the duct bottom plate 222 or the duct cover plate 221 at a later stage, and simplifies the manufacturing process of the duct mechanism 220.

[0050] Continue to refer to Figure 8 and Fig. 9 As shown, in some embodiments, the air duct mechanism 220 further includes an air duct connecting plate 223, and the top of the air duct bottom plate 222 is fixed in the frame mechanism 100 through the air duct connecting plate 223. For example, the air duct connecting plate 223 is connected to the wind cabinet of the integrated stove. In addition to the wind cabinet, the air duct connecting plate 223 can also be fixed to other components as long as the position can be fixed. Of course, in other embodiments, the top of the air duct cover plate 221 can also be fixed in the frame mechanism 100 through the air duct connecting plate 223.

[0051] The integrated stove has a smoke exhaust function. Depending on the direction of the smoke exhaust, it can be left or right. Figure 1 and Figure 2 Taking the left exhaust as an example, the integrated stove further includes an exhaust pipe 400, which is arranged on the side of the air intake fan assembly 200 away from the steaming and baking assembly 300 in the second direction. That is, the exhaust pipe 400 is arranged behind the air intake fan assembly 200.

[0052] In order to prevent the air duct mechanism 220 from squeezing the smoke exhaust pipe 400 and thus affecting the exhaust performance of the range hood, in some embodiments, part of the structure of the air duct mechanism 220 protrudes toward the side close to the steaming and baking assembly 300 to form a avoidance structure 2211 for avoiding the smoke exhaust pipe 400. Optionally, the avoidance structure 2211 is formed by pressing the air duct cover plate 221.

[0053] Furthermore, if Fig.10As shown, the opening width of the first air duct at the outlet of the first fan 210 is defined as X1, X1 is the opening width of the crossflow air duct, and the opening width of the first air duct at the avoidance structure 2211 is defined as X2, X2 is the opening width of the first air duct after being profiled. Define a = X2 / X1, in order to reduce the wind resistance caused by the narrowing of the first air duct to the air intake of the crossflow fan, a is limited to not less than 65%, that is, a ≥ 65%. Exemplarily, a is 65%, 70%, 75%, 80% or 85%. Of course, a can also be other values ​​within the range, which are not listed here one by one.

[0054] In some embodiments, the heat dissipation element 320 is a power board assembly. The power board assembly is used to provide electrical energy to the electrical components of the integrated stove. It should be noted that the specific structure of the power board assembly is a prior art and will not be described in detail here. Of course, in other embodiments, the heat dissipation element 320 can also be other components that need to dissipate heat, and is not limited to the power board assembly.

[0055] In some embodiments, the second fan 310 is a double-headed heat dissipation fan, which has the advantages of good cooling effect, good air circulation, and high air quality.

[0056] Continue to refer to Figure 3 As shown, the steaming and baking assembly 300 also includes a steam generator 330. The specific structure of the steam generator 330 is prior art and will not be described in detail here. In some embodiments, in the second direction, the steam generator 330 is arranged directly opposite the air outlet 201, the power board assembly is located on the side of the steam generator 330 away from the air outlet 201, and the power board assembly is extended along the third direction. In the third direction, the second fan 310 is spaced apart from the steam generator 330, and a partial second air duct is formed between the steam generator 330 and the first side plate 120 on the adjacent side of the frame mechanism 100, and the distance between the second fan 310 and the first side plate 120 is not less than the extension length of the power board assembly in the third direction. Such an arrangement allows the second air duct to be formed as follows: Figure 7 The U-shaped structure shown in the figure, specifically, the second air duct includes a first air duct section located between the steam generator 330 and the first side plate 120, a second air duct section located above the power board assembly, and a third air duct section located between the power board assembly and the second fan 310.

[0057] The integrated stove not only makes the internal structure of the integrated stove compact by rationally arranging the positions of the steam generator 330, the second fan 310 and the power board assembly, but also makes the cold air flowing out of the air outlet 201 enter the first air duct section of the second air duct after being blocked by the steam generator 330, so that more cold air is dispersed in the second air duct section above the power board assembly. Since the length of the second air duct section in the third direction is not less than the extension length of the power board assembly in the third direction, the heat dissipation airflow forms and flows through the entire power board assembly, thereby improving the heat dissipation effect of the power board assembly. It should be supplemented that if there is no obstruction by the steam generator 330, the air outlet 201 is directly opposite to the middle of the power board assembly, shortening the flow path of the heat dissipation airflow at the power board assembly, thereby reducing the heat dissipation effect.

[0058] In some embodiments, continue to refer to Figure 3 and Figure 7 As shown, the steaming and baking assembly 300 also includes a top heating fan assembly 340, and the top heating fan assembly 340 includes the above-mentioned heating fan. In the third direction, the top heating fan assembly 340 is arranged between the steam generator 330 and the second fan 310, and the heat dissipation airflow flows through the top heating fan assembly 340. It should be noted that the mechanism of the top heating fan assembly 340 is a prior art and is not described in detail here. Since the heat dissipation airflow flows through the top heating fan assembly 340, the cold air will mix with the hot air located above the top heating fan assembly 340, thereby playing a role in cooling the interior. In addition, it should be noted that when the second fan 310 is working, it can draw away the hot air and discharge it to the outside of the frame mechanism 100 through the left heat dissipation duct.

[0059] Of course, it is also possible to adjust the positions of the air inlet fan assembly 200 and the smoke exhaust pipe 400 so that they can be installed on the right side of the frame mechanism 100, and by adjusting the positions of the second fan 310, the steam generator 330, and the power board assembly, the above-mentioned U-shaped second air duct can be formed. At this time, when the second fan 310 is working, it can draw away the hot air and discharge it to the outside of the frame mechanism 100 through the heat dissipation air duct.

[0060] In short, the overall design of the integrated stove realizes bottom air intake and top exhaust, and utilizes the installation positions of its internal components (steam generator 330, top heating fan assembly 340, second fan 310, power board assembly) to form a second air duct that is conducive to air flow, effectively reducing the temperature rise inside the frame mechanism 100, and after testing and comparison, the temperature rise value at the power board assembly can be reduced by about 20K.

[0061] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
