Description

Technical Field

[0001] The utility model relates to the field of integrated stoves, in particular to an integrated stove multi-fan structure. Background Art

[0002] Integrated stove is a kitchen appliance that integrates multiple functions such as range hood, gas stove, disinfection cabinet, storage cabinet, etc. It is also called environmentally friendly stove or integrated environmentally friendly stove in the industry. It has the advantages of saving space, good fume extraction effect, energy saving, low consumption and environmental protection.

[0003] The principle is generally to generate negative pressure through the fan volute in the bellows below, and cooperate with the side suction cavity to suck the oil smoke away from above the stove.

[0004] Existing integrated stoves are generally single-fan structures, which generally increase the static pressure during smoking by improving the structure of the smoke chamber above the bellows, but this change is generally only a single-digit percentage increase. (In a fan, static pressure refers to the air pressure in the chamber where the fan is located, and static pressure directly affects factors such as the fan's efficiency, noise, and capacity.) When the static pressure is too low, the exhaust port cannot be opened smoothly to discharge the oil smoke.

[0005] There is also a technical solution as disclosed in CN106322471A, "turn on one fan when one stove is used as a kitchen, and turn on two fans when two stoves are used as kitchens at the same time" (paragraph 0012 of the specification), but this setting cannot increase the static pressure.

[0006] Therefore, the inventor conducted further research on this and developed an integrated stove multi-fan structure, which resulted in the present case. Utility Model Content

[0007] The utility model aims to provide an integrated stove multi-fan structure, which can effectively improve the fan static pressure of the integrated stove.

[0008] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0009] An integrated stove multi-fan structure, comprising

[0010] A bellows, which is divided into an upper cavity and a lower cavity by a partition, wherein both the upper cavity and the lower cavity are provided with a volute, wherein a fan is provided inside the volute; the upper cavity is connected with the smoking cavity above the integrated stove, the air outlet of the volute in the upper cavity is arranged at the partition and connected with the lower cavity, the air outlet of the volute in the lower cavity is arranged on the side wall of the bellows and connected with the outside, and the static pressure of the bellows is enhanced by the linear linkage of the volute of the upper cavity and the volute of the lower cavity.

[0011] By configuring the traditional bellows into an upper and lower cavity structure and installing a fan (volute) in the cavity, the static pressure between the air inlet end (smoking cavity) and the air outlet end (air outlet of the lower cavity volute) of the entire bellows can be increased, thereby improving the smoking efficiency. The linear arrangement here is different from the parallel arrangement in the background technology. The technical solution in the background technology cannot actually enhance the static pressure of the bellows, but simply increases the air volume.

[0012] Furthermore, the partition in the bellows is arranged at an angle, the volutes in the upper cavity and the lower cavity are arranged staggered in the vertical direction, and the air outlet of the volute in the upper cavity is located at the lowest point of the partition.

[0013] Since the volute is generally close to a circle, considering the space utilization of the bellows, staggering the two in space can effectively improve the space utilization.

[0014] Furthermore, the volutes and fans in the upper and lower cavities have the same specifications.

[0015] Furthermore, the partition in the bellows is arranged horizontally, and two volutes are arranged in the upper cavity thereof, and one volute is arranged in the lower cavity.

[0016] It is only necessary to ensure that a volute (with a fan inside the volute) is provided in the upper cavity and the lower cavity, and the air outlet of the worm wheel is provided as described above, and the number can be adjusted.

[0017] Further, the size of the volute in the upper cavity is smaller than the size of the volute in the lower cavity.

[0018] When the number of volutes in the upper cavity is greater than 1, the size of the volute can be relatively reduced, and the fan specifications are reduced along with the volute.

[0019] After adopting the above scheme, the utility model has the following advantages compared with the prior art:

[0020] By increasing the static pressure of the entire bellows, the oil fume removal efficiency of the entire system is improved and noise can be reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Figure 2 This is the second embodiment of the present utility model;

[0023] Description of symbols

[0024] Bellows 1, upper cavity 11, lower cavity 12,

[0025] Volute (21, 22), air outlet (23, 24), partition 3. DETAILED DESCRIPTION

[0026] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] like Figure 1 As shown, an integrated stove multi-fan structure includes a bellows 1 which is generally rectangular. A partition 3 is provided in the bellows 1. The partition 3 extends obliquely from the upper left to the lower right of the bellows 1 and is connected to the side wall in the middle of the right side of the bellows 1, dividing the bellows 1 into an upper cavity 11 and a lower cavity 12.

[0028] The upper cavity 11 and the lower cavity 12 are both provided with volutes (21, 22) of the same specification (with a fan in the volute), and the air outlet 23 of the volute 21 in the upper cavity 11 is connected to the lowest point on the right side of the partition and communicated with the lower cavity 12, that is, the connection between the upper and lower cavities 12 is only ventilated through the air outlet 23 to ensure smooth airflow; the air outlet 24 of the volute 22 in the lower cavity 12 is connected to the left side wall of the bellows 1, so as to discharge the oil smoke out of the bellows 1.

[0029] like Figure 2 As shown, the structure of another embodiment, the shape of the bellows 1 remains unchanged, but the internal partition is arranged in a horizontal state, and the bellows 1 is still divided into an upper cavity 11 and a lower cavity 12. The space of the upper cavity 11 is slightly smaller than that of the lower cavity 12. At the same time, two smaller volutes 21 are arranged side by side in the upper cavity 11, and a larger volute 22 is arranged in the lower cavity 12. The air outlets of the two volutes in the upper cavity 11 are connected to the lower cavity 12 through the partition.

[0030] The technical solution of the dual fans mentioned in the background technology has basically the same static pressure as that of the single fan, but the overall air volume is increased, and it is necessary to ensure that the specifications of the fans arranged side by side on the left and right are consistent, otherwise the static pressure will become smaller due to the inconsistent pressure difference on the left and right, and the noise generated will be greater.

[0031] The technical solution mentioned in the above embodiment can effectively increase the static pressure, thereby reducing the noise during operation. In the field of integrated stoves, the increase in static pressure is far better than the increase in air volume, especially for solving the problem that the public flue in high-rise commercial buildings has high static pressure and cannot exhaust smoke.

[0032] The above are only specific embodiments of the present utility model. At the same time, all words such as "upper, lower, left, right, middle" involved in the present utility model are for reference only and are not absolutely limiting. Any non-substantial changes made using the present utility model shall be deemed as an infringement of the protection scope of the present utility model.
