[0002] As a convenient kitchen appliance, integrated stoves have been widely used in people's family life. At present, the design and selection of integrated stove fan cover is a difficult problem in the industry, especially for integrated stoves with dual fan steam ovens. How to design effective air outlet and return air structures is the focus of research.

[0003] Most existing dual-fan cover solutions roughly design holes in the left and right fan covers, following the design principle of "return air in the center, outlet air around the sides." However, because the warmer air is located in the upper area of the fan cavity, while the cooler air is located in the lower area of the fan cavity, when the fan rotates clockwise, the warmer air is blown out of the right side of the fan cover, and the cooler air is blown out of the left side of the fan cover. This often results in a situation where one side is hotter and the other side is colder, affecting the steaming and baking effect of the steam oven. Therefore, how to design the holes in the fan cover to ensure uniform air temperature has become a technical problem that needs to be solved in this field.

[0004] In view of this, the art needs to propose a new steam oven fan cover, steam oven and integrated stove to solve the above problems. Utility Model Content

Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0033] First, the existing steam oven fan cover is described.

[0034] Most of the existing dual-fan cover solutions are roughly designed with holes in the left and right fan covers, following the design principle of "return air in the middle and outlet air on all sides". However, since the air with higher temperature in the fan cavity is located in the upper area of the fan cavity, and the air with relatively lower temperature is located in the lower area of the fan cavity, when the fan rotates clockwise, the air with higher temperature will be blown out from the right side of the fan cover, and the air with lower temperature will be blown out from the left side of the fan cover. Therefore, the temperature on one side is often high and the temperature on the other side is low, which affects the steaming and baking effect of the steam oven. In order to solve this problem, the following implementation method is proposed.

[0035] Example 1

[0036] In order to solve the problem that the air outlet holes on the fan cover of the existing steam oven 11 are not designed properly, resulting in high air outlet temperature on one side and low air outlet temperature on the other side, which affects the steaming and baking effect, Figure 1-Figure 5 As shown, the steam oven 11 of the present invention includes an inner container 111, and a first accommodating cavity 114 and a second accommodating cavity 115 protruding outward are provided on the side wall of the inner container 111. The first accommodating cavity 114 is arranged in the upper area of the inner container 111, and the second accommodating cavity 115 is arranged in the lower area of the inner container 111. A first fan 112 and a second fan 113 are arranged on the inner container 111, and the fan blades of the first fan 112 are arranged in the first accommodating cavity 114, and the fan blades of the second fan 113 are arranged in the second accommodating cavity 115. A first fan cover (not shown in the figure) and a second fan cover 116 are respectively provided at the openings of the first accommodating cavity 114 and the second accommodating cavity 115. The following is mainly introduced by taking the second fan cover 116 as an example. Second fan cover 116 is provided with an air outlet and a return air hole 1165. Return air hole 1165 is located in the center region of second fan cover 116. The air outlet includes a first air outlet 1161, which is located in a first side region (the left side region in the figure) of second fan cover 116. This allows air, driven by the fan, to flow into the center region of second fan cover 116 and out of the left side region of second fan cover 116. Steam oven 11 also includes a first heating tube (not shown) and a second heating tube 118. The first heating tube is located between first fan 112 and the first fan cover, and the second heating tube 118 is located between second fan 113 and second fan cover 116.

[0037] In the case of adopting the above embodiment, the first fan 112 and the second fan 113 are first fixed in the first accommodating chamber 114 and the second accommodating chamber 115, respectively. Then, the first fan cover plate and the second fan cover plate 116 are respectively installed at the openings of the first accommodating chamber 114 and the second accommodating chamber 115. During the use of the steam oven 11 of the present invention, the first fan 112 and the second fan 113 operate simultaneously. When the second fan 113 is operating, air in the lower area of the inner pot 111 enters the second accommodating chamber 115 through the return air hole 1165 on the second fan cover plate 116. After being heated by the second heating tube 118, the air is blown from the first air outlet hole 1161 on the left side of the second fan cover plate 116 to the lower area of the inner pot 111 under the action of the second fan 113. The air flow process when the first fan 112 is operating is similar, and the air is eventually blown to the upper area of the inner pot 111. It will not be described in detail here.

[0038] The advantage of the above arrangement is that, by providing the first and second accommodating cavities 114, 115, which protrude outwardly from the inner container 111 and are used to house the first fan 112, the second fan 113, and the first and second heating tubes 118, compared to an arrangement in which the fans and heating tubes protrude inwardly from the inner container 111, this embodiment avoids occupying the steaming and baking space within the inner container 111, thereby ensuring the steaming and baking capacity of the steam oven 11. Furthermore, since only one air outlet is provided on the left side of the second fan cover 116, the heated air can only be uniformly mixed within the second accommodating cavity 115 before being blown out in an orderly manner from the first air outlet 1161. This avoids the problem of high-temperature air and low-temperature air within the second accommodating cavity 115 being blown out from different sides of the second fan cover 116, which could affect the steaming and baking performance of the steam oven 11. At the same time, by staggering the first fan 112 and the second fan 113 in the vertical direction, the occurrence of double fan blowing is avoided, which causes heat accumulation in the middle of the steam oven 11 to cause temperature field disorder, resulting in uneven temperature field distribution inside the cavity, affecting the steaming and baking effect of the steam oven 11. On the other hand, the fan cover can also play a protective role, preventing the objects to be steamed and baked from getting too close to the fan blades during the steaming and baking process, causing danger.

[0039] In addition, those skilled in the art will understand that, although the first air outlet 1161 is mentioned above as being located in the left side region of the second fan cover 116, this is not the only arrangement, and those skilled in the art may also change or add the locations of the air outlets according to actual needs. For example, considering that heat tends to move upward in a free state, the air outlets on the second fan cover 116 may also include a second air outlet 1162 and a third air outlet 1163, with the second air outlet 1162 being located in the top region of the second fan cover 116, and the third air outlet 1163 being located at the intersection of the left side and the top of the fan cover, so that air carrying more heat can be blown out of the air outlets driven by the second fan 113. Alternatively, to further increase the air output, those skilled in the art may also dispose a fourth air outlet 1164 in the bottom region of the second fan cover 116. These changes are all within the scope of protection of the present invention.

[0040] It is also worth mentioning that Figure 5 As shown, when designing the first air outlet 1161, the second air outlet 1162, the third air outlet 1163 and the fourth air outlet 1164, technical personnel in this field should pay attention to the spacing between the holes. In order to avoid the structural strength of the fan cover being affected by the excessive density of the openings, technical personnel in this field can adopt the form of spaced openings when designing the air outlets, that is, the spacing between two air outlets is one air outlet hole, so as to ensure the structural strength of the fan cover.

[0041] The main embodiments of the present invention have been introduced above, and some preferred embodiments of the present invention will be introduced next.

[0042] Example 2

[0043] like Figure 4 As shown, in a possible embodiment, the steam oven 11 also includes a first heating tube (not shown in the figure) and a second heating tube 118. The first heating tube is arranged in the first accommodating cavity 114 and coiled on the outside of the first fan 112. The second heating tube 118 is arranged in the second accommodating cavity 115 and coiled on the outside of the second fan 113.

[0044] The advantage of the above-mentioned setting method is that compared with the aforementioned method of arranging the first heating tube and the second heating tube 118 respectively between the first fan 112 and the first fan cover and the second fan 113 and the second fan cover 116, the method of coiling the first heating tube and the second heating tube 118 on the outside of the first fan 112 and the second fan 113 in this embodiment can, on the one hand, reduce the depth of the first accommodating cavity 114 and the second accommodating cavity 115, thereby reducing the occupation of the first accommodating cavity 114 and the second accommodating cavity 115 on the internal space of the steam oven 11, and reducing the width of the steam oven 11 as a whole. On the other hand, since the heating tube is on the outside of the fan blade, it avoids arranging the heating tube on the air outlet channel of the fan to block the air flow intensity blown out by the fan. At the same time, the coiled form reduces the heating of the air around the fan, making the temperature field of the air around the fan more uniform, thereby making the temperature of the air blown out by the fan more uniform.

[0045] Example 3:

[0046] In a possible embodiment, a first guide plate and a second guide plate are provided on the first fan cover plate and the second fan cover plate 116 so that the airflow blown out from the air outlet can be evenly blown into the inner liner 111 after passing through the first guide plate and the second guide plate, thereby ensuring the uniformity of the temperature field distribution inside the inner liner 111.

[0047] Example 4:

[0048] Based on the arrangement of the first and second guide plates on the first and second fan covers 116 mentioned in the aforementioned third embodiment, in this embodiment, the first guide plate and / or the second guide plate are further arranged to have an adjustable guide direction.

[0049] The advantage of the above embodiment is that by setting the first guide plate and the second guide plate to be in a form with adjustable guide direction, technicians in this field can more flexibly control the direction of the airflow blown out by the first fan 112 and the second fan 113, so that the high-temperature airflow blown out from the first fan 112 and the second fan 113 can be blown more accurately onto the object to be steamed and baked, thereby improving the steaming and baking efficiency.

[0050] In addition, the utility model also provides an integrated stove 1, which includes the steam oven 11 of any one of the above embodiments, and also includes a range hood module 12, a stove module 13 and a main frame. The range hood module 12 is arranged above the stove module 13, and the steam oven 11, the range hood module 12 and the stove module 13 are all arranged on the main frame 14.

[0051] It should be noted that the above-mentioned embodiment is only used to illustrate the principle of the present invention and is not intended to limit the scope of protection of the present invention. Without departing from the principle of the present invention, those skilled in the art can adjust the above-mentioned structure so that the present invention can be applied to more specific application scenarios.

[0052] Thus far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
