[0043] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0044] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0045] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined.

[0046] In addition, in this application, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0047] The first aspect of the present application proposes an oven, which may be an oven with only a baking function, or a steaming oven with both baking and steaming functions, or a microwave-steam-oven with baking, microwave and steaming functions. Of course, as long as it has a baking function, it can be regarded as including an oven.

[0048] Combination Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7As shown, in some embodiments of the present application, the oven includes a first accommodating chamber 3300, a second accommodating chamber 3400, a flow equalizing plate 3200, an air duct 3700 and a cross-flow fan 6000. The second accommodating chamber 3400 is used to accommodate food (for example, food is placed in the second accommodating chamber 3400 through a baking tray 5000). That is, when food needs to be baked, the food needs to be placed in the second accommodating chamber 3400. After the food is baked, the food needs to be taken out of the second accommodating chamber 3400. The flow equalizing plate 3200 is used to separate the second accommodating chamber 3400 from the first accommodating chamber. The air duct 3700 connects the second accommodating chamber 3400 and the first accommodating chamber 3300 to realize the transmission of airflow. The air outlet 3710 of the air duct 3700 is designed to be flat, and the axial direction of the air outlet 3710 intersects with the axial direction of the air duct 3211. The cross-flow fan 6000 is used to drive the airflow to circulate between the air duct 3700, the first accommodating chamber 3300 and the second accommodating chamber 3400.

[0049] By setting up the flow equalizing plate 3200, the airflow flowing to the food is evenly distributed. By cooperating with the cross-flow fan 6000, the air outlet 3710 of the air duct 3700 can be designed to be flat, so that the airflow can be diffused more efficiently in the first accommodating chamber 3300, which is more conducive to the airflow to evenly pass through the air holes 3211, further improving the distribution uniformity of the airflow in the second accommodating chamber 3400 and reducing the temperature difference in the second accommodating chamber 3400.

[0050] Specifically, when the oven is working, the airflow is driven by the cross-flow fan 6000, and the airflow flows from the second accommodating chamber 3400 to the air duct 3700, thereby entering the first accommodating chamber 3300, and then flows to the second accommodating chamber 3400. Under the action of the cross-flow fan 6000, the airflow can form a circulating flow, fully utilizing the heat of the heating tube 4000 to achieve heat exchange with the food, thereby baking the food. During the circulation of the airflow and before it flows to the food, the airflow needs to first enter the first accommodating chamber 3300. The first accommodating chamber 3300 has a certain spatial volume, so that it can accommodate a certain amount of airflow. After the airflow enters the first accommodating chamber 3300, it will not immediately shoot into the second accommodating chamber 3400, but will diffuse in the first accommodating chamber 3300 under the obstruction of the cavity wall of the first accommodating chamber 3300. Since the airflow is in a jet shape when entering the first accommodating chamber 3300, the flow rate of the airflow can be reduced by setting the first accommodating chamber 3300, and the first accommodating chamber 3300 is equivalent to a buffer for the airflow. Since the equalizing plate 3200 separates the first accommodating chamber 3300 from the second accommodating chamber 3400, the equalizing plate 3200 can be regarded as at least a part of the cavity wall of the first accommodating chamber 3300.

[0051] Combination Figure 6 and Figure 7 As shown, the axial direction of the air vent 3211 intersects with the axial direction of the air outlet 3710, the axial direction of the air vent 3211 is the up-and-down direction, and the axial direction of the air outlet 3710 is the front-to-back direction. Since the air duct 3700 needs to be connected with the first accommodating chamber 3300, that is, the first accommodating chamber 3300 has an air inlet 3310, the axial direction of the air vent 3211 intersects with the axial direction of the air inlet 3310. The intersection here should be understood as intersection in space. For example, the axial direction of the air vent 3211 and the axial direction of the air inlet 3310 are projected onto a plane, and the two projections intersect or the extended lines of the two projections intersect, that is, the axial direction of the air vent 3211 is non-parallel to the axial direction of the air inlet 3310 / air outlet 3710. Since the airflow enters the first accommodating chamber 3300 in a jet-like shape, if the axial direction of the air hole 3211 is parallel to the axial direction of the air outlet 3710 / air inlet 3310, a part of the airflow will directly rush out of the air hole 3211 aligned with or close to the air outlet 3710, thereby affecting the uniform distribution of the airflow. The so-called direct rushing out means flowing in a direction roughly in the same direction as the axial direction of the air outlet 3710 and passing through the air hole 3211. In this embodiment, the axial direction of the air hole 3211 is designed to intersect with the axial direction of the air outlet 3710 / air inlet 3310, so that the airflow needs to turn from the air outlet 3710 / air inlet 3310 to pass through the air hole 3211, thereby allowing the airflow to diffuse more effectively in the first accommodating chamber 3300. Preferably, the axial direction of the air hole 3211 can be designed to be perpendicular to the axial direction of the air outlet 3710 / air inlet 3310 to maximize the uniform outflow of the airflow, for example, the axial direction of the air inlet 3310 / air outlet 3710 is the front-to-back direction, while the axial direction of the air hole 3211 is the up-down direction. It is understandable that the air inlet 3310 and the air outlet 3710 can be the same port, that is, the air outlet 3710 relative to the air duct 3700, and the air inlet 3310 relative to the first accommodating chamber 3300.

[0052] In the present embodiment, the airflow is transported by cooperating with the cross-flow fan 6000 and the air duct 3700. The cross-flow fan 6000 can be designed to be as long as possible without interfering with other components. That is to say, the cross-flow fan 6000 can achieve a long and narrow airflow while occupying a certain space volume. In this way, a larger range of suction can be achieved in the second accommodating cavity 3400, thereby accelerating the flow of heat and the heat exchange with the food. In addition, the cross-flow fan 6000 is particularly suitable for installation in a relatively thin oven.

[0053] The airflow driven by the cross-flow fan 6000 needs to be transmitted to the first accommodating chamber 3300 through the air duct 3700. The air outlet airflow formed by the cross-flow fan 6000 is long and narrow, so the air duct 3700 also needs to be designed to adapt to the length of the cross-flow fan 6000, so that the air outlet 3710 of the air duct 3700 is flat. The so-called flat shape means a relatively long length and a relatively small width / height. When the airflow flows out from the air outlet 3710 and enters the first accommodating chamber 3300, the airflow occupies a larger area in the space roughly parallel to the flow equalizing plate 3200, so that it can diffuse into the first accommodating chamber 3300 more quickly.

[0054] For example, combined with Figure 6 and Figure 7 As shown, in the left-right direction, the air outlet 3710 has a larger length, and in the up-down direction, the air outlet 3710 has a relatively smaller height, so that the air outlet 3710 is flat. Of course, in other embodiments, the air outlet 3710 may not be a symmetrical rectangle, but may be other irregular shapes, but as long as it has a relatively large length in one direction and a relatively small width / height in another direction, it will be fine.

[0055] As the airflow enters the first accommodating chamber 3300 and diffuses, the air pressure in the first accommodating chamber 3300 gradually increases, and then the airflow in the first accommodating chamber 3300 flows out through the air holes 3211 and then enters the second accommodating chamber 3400. Since there are multiple air holes 3211, the airflow can flow out from the multiple air holes 3211 to the second accommodating chamber 3400, and the multiple air holes 3211 can form a larger coverage of the second accommodating chamber 3400. Based on the premise that the airflow effectively diffuses in the first accommodating chamber 3300, the airflow can be made more uniform when it flows out of different air holes 3211, so that the distribution of the airflow at different positions of the second accommodating chamber 3400 can be more uniform, and the differences in the airflow velocity, temperature, and flow rate at different positions of the second accommodating chamber 3400 are minimized to the maximum extent, thereby achieving uniform baking of the food.

[0056] In order to further improve the diffusion speed of the airflow in the first accommodating chamber 3300, the size relationship between the air outlet 3710 and the flow equalizing plate 3200 can be optimized. Figure 8 As shown, along the first direction, the size of the equalizer plate 3200 is L1, and the size of the outlet 3710 is L2, which needs to satisfy L2 ≥ 0.5L1, preferably L2 ≥ 0.75L1, and L2 can even be designed to be equal to L1. The first direction here means the length direction of the outlet 3710, and is roughly horizontal to the equalizer plate 3200, as shown in FIG. Figure 8The left and right directions shown are because, generally speaking, the flow equalizing plate 3200 needs to be designed to be roughly rectangular in conjunction with the first accommodating cavity 3300 and the second accommodating cavity 3400. When the size of the air outlet 3710 satisfies the above relationship, when the airflow flows out from the air outlet 3710, it can cover more than half of the area of ​​the flow equalizing plate 3200 in a roughly horizontal direction. In this way, when the airflow diverges and flows, it can occupy the remaining space of the first accommodating cavity 3300 as quickly as possible, thereby effectively improving the diffusion speed of the airflow in the first accommodating cavity 3300.

[0057] In some embodiments of the present application, Figure 3 and Figure 5 As shown, the flow equalizing plate 3200 is arranged above the food. In this way, the air vent 3211 is also located above the food, further ensuring the baking effect of the food. For example, the first accommodating chamber 3300 is arranged above the second accommodating chamber 3400, or the first accommodating chamber 3300 is arranged at an upper position of the second accommodating chamber 3400. The orientation in this article is based on the normal placement of the oven. Since the flow equalizing plate 3200 separates the first accommodating chamber 3300 and the second accommodating chamber 3400, after the food is placed in the second accommodating chamber 3400, the flow equalizing plate 3200 is located above the food. When the oven is working, the airflow has a certain high temperature, and the high temperature makes the airflow tend to float upward. When the airflow flows out from the first accommodating chamber 3300 through the air vents 3211, the airflow gradually fills the second accommodating chamber 3400 from top to bottom. In the process of the airflow filling from top to bottom and before reaching the food, the airflow has enough space and time to achieve further mixing and enhance the effect of uniform distribution. When the airflow reaches the surface of the food, it ensures that the food is heated evenly to the maximum extent.

[0058] In some embodiments of the present application, Figure 6 and Figure 7 As shown, the first accommodating cavity 3300 is provided with an air inlet 3310, and the air duct 3700 needs to be inserted into the air inlet 3310 to facilitate the cooperation between the air duct 3700 and the first accommodating cavity 3300, thereby realizing the transmission of airflow.

[0059] Specifically, the airflow in the second accommodating chamber 3400 needs to be transmitted to the first accommodating chamber 3300 through the air duct 3700, that is, the first accommodating chamber 3300 has a corresponding air inlet 3310 and cooperates with the air duct 3700. In the present embodiment, the air duct 3700 is a separate component relative to the first accommodating chamber 3300, so that the manufacture of the air duct 3700 is convenient. On the premise that the first accommodating chamber 3300 needs to have an air inlet 3310, the air duct 3700 is directly inserted into the air inlet 3310, so that the air outlet 3710 of the air duct 3700 is connected with the air inlet 3310, that is, connected with the first accommodating chamber 3300. The air duct 3700 is inserted into the first accommodating chamber 3300, and the contour of the air inlet 3310 forms a restriction on the air duct 3700. The structure is simple and the assembly is convenient.

[0060] In some embodiments of the present application, Figure 5 As shown, the crossflow blower 6000 includes a crossflow impeller 6100, and the crossflow impeller 6100 is disposed in the second accommodating cavity 3400, which is more conducive to the arrangement of the structures of various components.

[0061] Specifically, the cross-flow fan 6000 includes a cross-flow fan 6000 and a motor (not shown in the figure), and the motor drives the cross-flow fan wheel 6100 to rotate, thereby driving the air flow. Since the second accommodating chamber 3400 is used to accommodate food, the second accommodating chamber 3400 occupies a larger spatial volume than the first accommodating chamber 3300. Therefore, the cross-flow fan wheel 6100 is arranged in the second accommodating chamber 3400, so that there is enough space to install the cross-flow fan wheel 6100, and the cross-flow fan wheel 6100 can directly suck the airflow in the second accommodating chamber 3400, accelerate the flow of air in the second accommodating chamber 3400, and further make the temperature distribution in the second accommodating chamber 3400 more uniform.

[0062] In some embodiments of the present application, Figure 5 As shown, the crossflow fan 6000 also includes a mounting seat 6200, and the crossflow impeller 6100 needs to be installed in the mounting seat 6200, and one end of the air duct 3700 is inserted into the mounting seat 6200. Specifically, the design of the mounting seat 6200 provides a basis for the installation of the crossflow impeller 6100, and the mounting seat 6200 constitutes a volute structure, so that the crossflow impeller 6100 can better suck airflow and guide the airflow flow, and because the airflow sucked by the crossflow impeller 6100 needs to be transmitted through the air duct 3700, the design of the mounting seat 6200 is also convenient for cooperation with the air duct 3700, so that the airflow is transmitted from the mounting seat 6200 to the air duct 3700. Since it is only necessary to drive the airflow inside the oven, the plug-in connection between the air duct 3700 and the mounting seat 6200 in this embodiment can meet the requirements at the lowest cost.

[0063] In some embodiments of the present application, Figure 5 As shown, the cross-flow blower 6000 and the air duct 3700 are arranged at the rear of the first accommodating chamber 3300 and the second accommodating chamber 3400, so that the cross-flow blower 6000 and the air duct 3700 can be hidden as much as possible to avoid being touched by users, thereby improving the aesthetics.

[0064] In some embodiments of the present application, Figure 5 As shown, in some embodiments of the present application, the oven includes a cavity 3100, and the flow equalizing plate 3200 is arranged inside the cavity 3100, thereby dividing the interior of the cavity 3100 into a first accommodating cavity 3300 and a second accommodating cavity 3400, thereby facilitating the formation of the first accommodating cavity 3300 and the second accommodating cavity 3400. There are multiple ways in which the flow equalizing plate 3200 divides the interior of the cavity 3100 into the first accommodating cavity 3300 and the second accommodating cavity 3400.

[0065] For example, the oven includes a shell 1000, the shell 1000 wraps the cavity 3100, and the shell 1000 and the cavity 3100 are arranged alternately, so that there is a certain space between the shell 1000 and the cavity 3100, so that other components of the oven, such as an electric control module, etc., can be placed between the shell 1000 and the cavity 3100. Of course, in other embodiments, the shell 1000 may not be provided, or the shell 1000 does not necessarily wrap the cavity 3100, but is arranged side by side with the cavity 3100. The cavity 3100 is a hollow structure, including a top plate 3110, a bottom plate 3120, a side plate and a rear plate 3150. It can be understood that, generally speaking, the oven is formed as a cube as a whole, so the cavity 3100 is also formed as a cube, then there is a left side plate 3130 and a right side plate 3140 between the top plate 3110 and the bottom plate 3120, and the left side plate 3130 and the right side plate 3140 are collectively referred to as side plates, and the rear plate 3150 is arranged between the top plate 3110 and the bottom plate 3120, and between the left side plate 3130 and the right side plate 3140, so that the space enclosed by the cavity 3100 is open to the front, that is, the open end of the cavity 3100 constitutes an opening 3500, and the oven has a door body 2000, and the door body 2000 can be opened and closed, thereby realizing the opening and closing of the opening 3500.

[0066] In this embodiment, the current balancing plate 3200 is connected to the side wall. Specifically, the current balancing plate 3200 is connected to the left plate 3130 and the right plate 3140. It can be understood that the connection between the current balancing plate 3200 and the side plates (the left plate 3130 and the right plate 3140) can be a direct connection or an indirect connection, as long as the current balancing plate 3200 can be fixed to the side plates (the left plate 3130 and the right plate 3140). In this way, the flow equalizing plate 3200 and the top plate 3110 cooperate to enclose the first accommodating cavity 3300, making full use of the upper space of the cavity 3100, so that the first accommodating cavity 3300 is as large as possible, and the corresponding size of the flow equalizing plate 3200 can also be designed to be larger. As mentioned above, generally speaking, the cavity 3100 is relatively square. By installing the flow equalizing plate 3200 in this way, the flow equalizing plate 3200 can form a larger coverage of the second accommodating cavity 3400 from top to bottom. Since the size of the flow equalizing plate 3200 is larger, the number of air holes 3211 set on the flow equalizing plate 3200 can also be more, so that the multiple air holes 3211 can form a larger coverage of the food from top to bottom, and then the distribution of the air flow flowing out of the air holes 3211 is more uniform.

[0067] In some embodiments of the present application, Figure 3 and Figure 4 As shown, the heating of the airflow is achieved through the heating tube 4000, and the heating tube 4000 is installed below the equalizing plate 3200. When the airflow flows out from the multiple air holes 3211, an air curtain can be formed. It is precisely because the heating tube 4000 is arranged below the equalizing plate 3200 that the air curtain formed by the airflow can quickly take away the heat emitted by the heating tube 4000 and carry the heat to the food to exchange heat with the food. Since the food needs to be placed in the second accommodating cavity 3400, and the heating tube 4000 is also arranged in the second accommodating cavity 3400, it is conducive to maximizing the use of the heat emitted by the heating tube 4000 and avoiding heat waste.

[0068] Multiple bends are formed between the two ends of the heating tube 4000, so that the heating tube 4000 can form a larger coverage in the second accommodating cavity 3400, thereby reducing the number of heating tubes 4000, thereby improving the installation efficiency. That is, when the heating tube 4000 forms multiple bends, the heating tube 4000 can occupy a larger spatial range in the second accommodating cavity 3400, so that the airflow can be heated at multiple positions in the second accommodating cavity 3400, thereby improving the heating efficiency. It can be understood that the multiple paths referred to here mean at least two paths. Since the heating tube 4000 is bent, a larger coverage can be achieved, so the number of heating tubes 4000 can be reduced, thereby reducing costs, and since the heating tube 4000 needs to be installed and fixed, reducing the number of heating tubes 4000 also improves the installation efficiency of the product.

[0069] In some embodiments of the present application, the heating tube 4000 needs to be connected and fixed to the side wall of the cavity 3100, so as not to affect the movable setting of the flow equalizing plate 3200.

[0070] Specifically, the flow balancing plate 3200 is movable relative to the cavity 3100 so that it can leave the cavity 3100 and be placed in the cavity 3100. Since the internal environment of the cavity 3100 is the cooking environment of the food, the flow balancing plate 3200 is easily contaminated. The flow balancing plate 3200 can leave the cavity 3100, so that the flow balancing plate 3200 can be exposed to the outside, which is convenient for the user to clean the flow balancing plate 3200 without hindrance. When the flow balancing plate 3200 is installed inside the cavity 3100, the flow balancing plate 3200 can divide the interior of the cavity 3100 into a first accommodating chamber 3300 and a second accommodating chamber 3400, and the food is placed in the second accommodating chamber 3400, and the second accommodating chamber 3400 is connected to the first accommodating chamber 3300 through the air vents 3211 set on the flow balancing plate 3200.

[0071] For example, the equalizing plate 3200 is set to be detachable, that is, the equalizing plate 3200 needs to be detachably connected to the cavity 3100. Removable means that the equalizing plate 3200 can be detached from the cavity 3100 when it needs to be cleaned or used for other purposes. The process of detaching the equalizing plate 3200 from the cavity 3100 is regarded as leaving the cavity 3100. In this way, the equalizing plate 3200 can be completely separated from the cavity 3100, which is convenient for cleaning or other purposes. When the equalizing plate 3200 is needed to achieve equal flow of airflow, the equalizing plate 3200 can be installed in the cavity 3100 and fixed. The process of installing the equalizing plate 3200 in the cavity 3100 is regarded as inserting it into the cavity 3100.

[0072] The detachable connection of the current balancing plate 3200 can be, combined with Figure 4As shown, the oven includes a supporting portion 3600, which is arranged on opposite sides of the cavity 3100, and the flow equalizing plate 3200 is overlapped on the supporting portion 3600, so that the supporting portion 3600 cooperates with the supporting portion 3600 to achieve a detachable connection, and the support portion 3600 can be used to install the flow equalizing plate 3200 and conveniently disassemble the flow equalizing plate 3200. Specifically, the opposite sides of the cavity 3100 are a left plate 3130 and a right plate 3140, respectively, and the supporting portion 3600 is fixed on the left plate 3130 and the right plate 3140, respectively, and the flow equalizing plate 3200 is overlapped on the supporting portion 3600. The so-called overlap means that the flow equalizing plate 3200 abuts against the supporting portion 3600 in the direction of gravity, so that the supporting portion 3600 can support the entire flow equalizing plate 3200, so that the detachable installation of the flow equalizing plate 3200 is achieved. In this way, not only can the current balancing plate 3200 be easily installed in the cavity 3100, but when the current balancing plate 3200 needs to be removed, the user only needs to lift the current balancing plate 3200 or pull the current balancing plate 3200 to separate the current balancing plate 3200 from the supporting part 3600, which is convenient, fast and low-cost.

[0073] The cavity wall of the cavity 3100 is composed of a bottom plate 3120, a top plate 3110, a rear plate 3150 and a side plate. The bottom plate 3120 constitutes the bottom cavity wall of the cavity 3100, the top plate 3110 constitutes the top cavity wall of the cavity 3100, the side plates (left plate 3130, right plate 3140) and the rear plate 3150 constitute the side wall of the cavity 3100, and the heating tube is connected to the left plate 3130, the right plate 3140 and the rear plate 3150, so as to fix the heating tube without affecting the movement of the current equalizing plate 3200.

[0074] For example, combined with Figure 3 , Figure 4 and Fig. 9 As shown, the heating tube 4000 is installed on the side wall of the cavity 3100 by setting the first connecting member 7100 and the second connecting member 7200. The first connecting member 7100 and the two ends of the heating tube 4000 are connected and fixed, and are connected to the back plate 3150. The opposite sides of the heating tube 4000 are connected by the second connecting member 7200 respectively. The second connecting member 7200 on the left is connected to the left plate 3130 and the heating tube 4000, and the second connecting member 7200 on the right is connected to the right plate 3140 and the heating tube 4000. In this way, the heating tube 4000 can be installed without affecting the movable setting of the flow equalizing plate 3200.

[0075] In some embodiments of the present application, Figure 6 , Figure 7 and Figure 8As shown, the first accommodating cavity 3300 is provided with an air inlet 3310, the air duct 3700 is connected to the air inlet 3310, and the aperture of the air vent 3211 close to the air inlet 3310 needs to be designed to be smaller than the aperture of the air vent 3211 away from the air inlet 3310, so that the airflow flowing into the second accommodating cavity 3400 is more uniform.

[0076] Specifically, as mentioned above, the air duct 3700 can be inserted into the air inlet 3310, so as to realize the transmission of airflow to the first accommodating chamber 3300. When the airflow flows and enters the first accommodating chamber 3300, the air holes 3211 close to the air inlet 3310 will first contact the airflow for outflow, while the air holes 3211 away from the air inlet 3310 will contact the airflow later. Therefore, the air flow rate of the air holes 3211 close to the air inlet 3310 will be larger, while the air flow rate of the air holes 3211 away from the air inlet 3310 will be relatively small. In order to further improve the distribution uniformity of the airflow when it flows into the second accommodating chamber 3400, this embodiment optimizes the size of the air holes 3211.

[0077] That is, the aperture of the air hole 3211 near the air inlet 3310 is designed to be smaller than the aperture of the air hole 3211 far from the air inlet 3310. Although the air hole 3211 near the air inlet 3310 is first in contact with the air flow and allows the air flow to pass through, and the air hole 3211 far from the air inlet 3310 is later in contact with the air flow and allows the air flow to pass through, since the aperture of the air hole 3211 near the air inlet 3310 is relatively small, and the aperture of the air hole 3211 far from the air inlet 3310 is relatively large, the air flow rate flowing out from the air hole 3211 near the air inlet 3310 and the air flow rate flowing out from the air hole 3211 far from the air inlet 3310 can be balanced, thereby further improving the uniformity of air flow distribution in the second accommodating chamber 3400.

[0078] The aperture of the air hole 3211 near the air inlet 3310 mentioned above is designed to be smaller than the aperture of the air hole 3211 far from the air inlet 3310. It should be understood as follows: there are at least two air holes 3211 on the flow equalizing plate 3200, and lines are drawn between the two air holes 3211 and the air inlet 3310. If the length of one line is greater than the length of the other line, then the air hole 3211 with a larger line length is far from the air inlet 3310, and the air hole 3211 with a smaller line length is close to the air inlet 3310. By setting it in this way, the equalization of the air flow is further improved, so that the air flow is more evenly distributed in the second accommodating cavity 3400, and the food in different positions is heated evenly to the maximum extent, thereby improving the baking effect of the food.

[0079] The second aspect of the present application discloses an integrated stove, which includes the oven of the above-mentioned embodiment. The so-called integrated stove, for example, can combine a stove, a range hood and an oven to form a combined household appliance. The stove, the range hood and the oven can be used separately without affecting each other. The stove, the range hood and the oven are integrated together. Compared with independent stoves, range hoods and ovens, the integrated stove can save space more effectively, making the integrated stove more and more popular. It is understandable that in addition to the integrated stove, the range hood and the oven, the integrated stove can also be integrated with other types of household appliances, which will not be repeated here. The oven included in the integrated stove of this embodiment adopts the technical solution of the above-mentioned embodiment, so it at least has the beneficial effects brought by the technical solution of the above-mentioned embodiment, which will not be repeated here.
