Description

Technical Field

[0001] The present invention relates to the technical field of kitchen appliances, and specifically provides a steam oven and an integrated stove comprising dual fans. Background Art

[0002] Integrated stoves, as convenient kitchen appliances, have become a widespread fixture in most households. Currently, integrated stove steam ovens are striving for larger volumes. However, traditional single-fan blowers, due to their low air volume, are unable to fully fill the oven cavity with heat, failing to meet the temperature field requirements of large-volume steam ovens. This has led to the emergence of dual-fan steam ovens. Dual-fan technology is now relatively mature, with solutions already featuring two fans placed at the same height on the back of the oven or on the left and right sides, along with heating tubes installed at the top or bottom of the oven cavity. However, during use, the opposing blowers at the same height can cause heat to accumulate in the center of the oven cavity, disrupting the temperature field and leading to an uneven temperature distribution within the cavity, impacting the steaming and baking performance of the oven.

[0030] First, the existing steam oven is described.

[0031] Currently, steam ovens on the market include small-volume single-fan steam ovens and large-volume dual-fan steam ovens. Due to the small volume of small-volume single-fan steam ovens, in actual use, the volume is often insufficient, resulting in the need for multiple steaming and baking, which is complicated to operate. Therefore, small-volume steam ovens have gradually evolved into large-volume steam ovens. As the volume of large-volume steam ovens increases, a single fan cannot meet the large-volume requirements for the temperature field inside the steam oven, so dual-fan steam ovens came into being. Existing dual-fan steam ovens usually have two fans installed at the same height on the back or left and right side walls of the steam oven. However, in actual use, it is found that when two fans of the same height blow air at the same height inside the steam oven at the same time, airflow interference occurs between them, resulting in a turbulent temperature field inside the steam oven and an uneven temperature field distribution inside the cavity, thereby affecting the steaming and baking effect of the steam oven. In order to solve this problem, the following implementation method is proposed.

[0032] Example 1

[0033] like Figure 1-Figure 3As shown, in order to solve the problem that the existing dual-fan steam oven 11 causes heat accumulation in the middle of the steam oven 11 due to the opposing blowing of the dual fans, resulting in a disordered temperature field, uneven distribution of the temperature field inside the cavity, and affecting the steaming and baking effect of the steam oven 11, the steam oven 11 containing dual fans of the present invention includes an inner tank 111, and a first accommodating cavity 114 and a second accommodating cavity 115 protruding outward are provided on the side wall of the inner tank 111. The first accommodating cavity 114 is arranged in an upper area inside the inner tank 111, and the second accommodating cavity 115 is arranged in a lower area inside the inner tank 111. A first fan 112 and a second fan 113 are provided on the inner tank 111. 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. The first fan 112 and the second fan 113 are electrically connected to the control system of the steam oven 11. A first fan cover (not shown) and a second fan cover 116 are respectively disposed at the openings of the first and second accommodating chambers 114, 115. The first fan cover is provided with a first ventilation hole (not shown), and the second fan cover 116 is provided with a second ventilation hole 117, allowing air within the inner container 111 to circulate within the first and second accommodating chambers 114, 115. The first and second ventilation holes 117 are evenly distributed on the first and second fan covers 116, allowing airflow from the first and second fans 112, 113 to pass through the first and second ventilation holes 117 and be evenly distributed within the inner container 111. The steam oven 11 also includes a first heating tube 118 and a second heating tube. The first heating tube 118 is disposed between the first fan 112 and the first fan cover, and the second heating tube is disposed between the second fan 113 and the second fan cover 116. The first and second heating tubes 118 and 116 are electrically connected to the control system of the steam oven 11. The steam oven 11 also includes a detachable partition 119, which is located between the first fan 112 and the second fan 113 and can divide the inner tank 111 into two upper and lower cavities; the steam oven 11 has a single-cavity working mode and a double-cavity working mode. When the partition 119 is not detected, the steam oven 11 operates in the single-cavity working mode. When the partition 119 is detected, the steam oven 11 operates in the double-cavity working mode. In the single-cavity working mode, the first fan 112 and the second fan 113 are configured to work simultaneously or alternately; in the double-cavity working mode, the first fan 112 and the second fan 113 are configured to work independently and selectively.

[0034] When adopting the above embodiment, the first fan 112 and the second fan 113 are first fixed in the first accommodating cavity 114 and the second accommodating cavity 115 respectively, and then the first fan cover and the second fan cover 116 are installed at the openings of the first accommodating cavity 114 and the second accommodating cavity 115 respectively. During the use of the steam oven 11 containing dual fans of the present invention, in the single-cavity working mode, the first fan 112 and the second fan 113 operate simultaneously or alternately. When the first fan 112 is operating, the air in the upper area of ​​the inner tank 111 enters the first accommodating cavity 114 through the first ventilation hole on the first fan cover, and after being heated by the first heating tube 118, it is blown from the first ventilation hole to the upper area of ​​the inner tank 111 under the action of the first fan 112. Similarly, when second fan 113 is operating, air from the lower area of ​​liner 111 enters second accommodating chamber 115 through second ventilation holes 117 on second fan cover 116. After being heated by the second heating tube, air is blown from second ventilation holes 117 to the lower area of ​​liner 111 by second fan 113. In dual-chamber operating mode, first fan 112 and second fan 113 are configured to operate independently, blowing air into the upper and lower chambers of liner 111, respectively.

[0035] The advantage of the above-mentioned setting method is that: since the first fan 112 and the second fan 113 are arranged at different heights of the inner tank 111 of the steam oven 11, and a detachable partition 119 is arranged between the first fan 112 and the second fan 113, the partition 119 can divide the inner tank 111 into two upper and lower chambers. During the process of using the steam oven 11 containing dual fans of the present invention for steaming and baking, when the partition 119 is not detected to be installed in the inner tank 111, the steam oven 11 operates in a single-cavity working mode to control the operation of the first fan 112 and the second fan 113; when the partition 119 is detected to be installed in the inner tank 111, the steam oven 11 operates in a dual-cavity working mode, so that the first fan 112 and the second fan 113 can blow air to areas at different heights in the inner tank 111, avoiding the situation where the two fans blow against each other. The heat generated by the first and second heating tubes 118 and 113 is mixed and blown out by the first and second fans 112 and 113, making the temperature field inside the inner container 111 more evenly distributed and improving the steaming and baking effect of the steam oven 11. By providing the inner container 111 with the first and second accommodating cavities 114 and 115 protruding outward for accommodating the first and second fans 112, 113, and the first and second heating tubes, this embodiment avoids occupying the space inside the inner container 111 used for steaming and baking, compared to an arrangement where the fans and heating tubes protrude inward from the inner container 111, thereby ensuring the steaming and baking capacity of the steam oven 11. In addition, by providing the first and second fan covers 116 at the openings of the first and second accommodating cavities 114 and 115 and by evenly providing ventilation holes on the fan covers, it is ensured that the airflow blown out from the first and second fans 112 and 113 can evenly cover the upper and lower areas of the inner container 111. At the same time, the steam oven 11 of the present invention can also control the first and second fans 112, 113, first heating tubes 118 and second heating tubes respectively, so that the first and second fans 112, 113, first heating tubes 118 and second heating tubes can steam and bake different areas of the inner container 111 according to the actual needs of the steaming and baking process, further ensuring 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 from getting too close to the fan blades during the steaming and baking process, which may cause danger.

[0036] In addition, those skilled in the art will understand that although the above mentioned method of evenly distributing the first and second ventilation holes 117 on the first fan cover plate and the second fan cover plate 116 is mentioned, this is not the only embodiment. It is only a more preferred embodiment. Those skilled in the art can also choose other embodiments according to actual needs, such as evenly distributing the ventilation holes only on the first fan cover plate or the second fan cover plate 116. These changes do not exceed the technical principles of the present invention and are therefore included in the scope of protection of the present invention.

[0037] The main embodiments of the present invention have been introduced above. Next, some preferred embodiments of the present invention will be introduced.

[0038] Example 2

[0039] like Figure 3 As shown, in a possible embodiment, the steam oven 11 also includes a first heating tube 118 and a second heating tube (not shown in the figure), the first heating tube 118 is arranged in the first accommodating cavity 114 and coiled on the outside of the first fan 112, and the second heating tube is arranged in the second accommodating cavity 115 and coiled on the outside of the second fan 113.

[0040] The advantage of the above-mentioned setting method is that compared with the aforementioned method of arranging the first heating tube 118 and the second heating tube between the first fan 112 and the first fan cover and the second fan 113 and the second fan cover 116 respectively, the method of coiling the first heating tube 118 and the second heating tube 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.

[0041] Example 3:

[0042] 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 first ventilation hole and the second ventilation hole 117 can be evenly blown into the inner tank 111 after passing through the first guide plate and the second guide plate.

[0043] The advantage of the above embodiment is that compared with the aforementioned method of evenly arranging ventilation holes on the first fan cover plate and the second fan cover plate 116, technicians in this field can further arrange guide plates at the ventilation holes to control the direction of the airflow blowing toward the inner liner 111, thereby making the airflow blowing toward the inner liner 111 more uniform, thereby ensuring the uniformity of the temperature field distribution inside the inner liner 111.

[0044] Example 4:

[0045] 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.

[0046] 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.

[0047] In addition, the present invention also provides an integrated stove 1, which includes a steam oven 11 including a dual-fan fan according to any one of the above-mentioned 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.

[0048] It should be noted that the above-mentioned embodiments are only used to illustrate the principles of the present invention and are not intended to limit the scope of protection of the present invention. Without departing from the principles 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.

[0049] 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 will be 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.
