[0026] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0028] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0029] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0030] See also Figures 1 to 4 As shown, according to an embodiment of the present invention, a kitchen air conditioner is provided, which has an air outlet pipe 1, and a nozzle 2 is provided at the free end of the air outlet pipe 1. The kitchen air conditioner can spray an air curtain 3 through the nozzle 2, and the air curtain 3 is used to form a barrier between the stove and the cook.

[0031] In this technical solution, since the air curtain 3 ejected by the kitchen air conditioner through the nozzle 2 forms a barrier between the stove and the cook, the air curtain 3 can block the hot oil splashing out of the stove, thereby preventing the hot oil from splashing onto the cook. At the same time, the air curtain 3 can also reduce the impact of the heat during cooking on the human body.

[0032] See also Figures 1 to 3 As shown, the nozzle 2 has a straight-line air outlet, and the air curtain 3 sprayed out by the nozzle 2 is square. The air curtain 3 is located between the stove and the cook.

[0033] In this embodiment, the nozzle 2 has a straight-line air outlet, which simplifies the design of the nozzle 2 and facilitates manufacturing. Furthermore, since the square air curtain 3 is located between the stove and the cook, it acts like a wind wall to block splashing hot oil, thereby preventing the hot oil from splashing onto the cook.

[0034] As another embodiment, the nozzle 2 has an annular air outlet, and the air curtain 3 sprayed out by the nozzle 2 is annular, and the air curtain 3 surrounds the outer peripheral side of the stove.

[0035] In this technical solution, the hot oil in the stove will not only splash onto the cook, but also splash in other directions, such as onto the kitchen walls and stove. When the air curtain 3 sprayed out by the nozzle 2 is annular, and the annular air curtain 3 surrounds the outer circumference of the stove, the air curtain 3 can form a barrier in the circumference of the entire stove, so that the hot oil in the stove cannot splash in any direction, which can not only prevent the hot oil from splashing onto the cook, but also prevent the hot oil from splashing onto the kitchen walls and stove, which is more conducive to ensuring a clean and tidy kitchen environment. It should be noted that the schematic diagram of the nozzle 2 with an annular air outlet is as shown in FIG. Figure 4 As shown, the middle area of the nozzle 2 is blocked, leaving only the four sides to vent air. It is understandable that when there are multiple nozzles 2 with straight-line air outlets surrounding the outer periphery of the cooker, they can also form an air curtain 3 similar to a ring.

[0036] See also Figure 1 As shown, the nozzle 2 is directed upward toward the range hood from bottom to top, and the air curtain 3 sprayed by the nozzle 2 is sucked away by the range hood.

[0037] In this embodiment, although the air curtain 3 can block the splashing hot oil, in the process of blocking the splashing of hot oil, oil smoke will be mixed into it to a greater or lesser extent. When the nozzle 2 is directed from bottom to top toward the range hood and the air curtain 3 is sucked away by the range hood, the oil smoke in the air curtain 3 can be prevented from affecting the kitchen environment, thereby further ensuring the cleanliness and tidiness of the kitchen environment.

[0038] See also Figure 1 As shown, the air outlet main pipe 1 is connected to an air outlet branch pipe 4, which is used to supply air to the cook.

[0039] In this technical solution, by designing the air outlet branch pipe 4 so that the air outlet branch pipe 4 supplies air to the cook, the human comfort can be improved.

[0040] See also Figure 1 As shown, the air outlet main pipe 1 includes a vertical section 11 extending in the up-down direction, the nozzle 2 is arranged at the free end of the vertical section 11, the air outlet branch pipe 4 is connected to the vertical section 11, and an angle a is formed between the air outlet branch pipe 4 and the vertical section 11, 30°≤a≤60°.

[0041] In this embodiment, the gas stove 9 is in Figure 1 The cook is in the middle left position Figure 1 At the center right position, when the angle a formed between the outlet branch pipe 4 and the vertical section 11 of the main outlet pipe 1 is between 30° and 60°, the outlet of the outlet branch pipe 4 can be tilted upward, providing a more comfortable experience for the human body during air delivery. It should be noted that the outlet branch pipe 4 also has a horizontal section 12 connected to the vertical section 11, and the horizontal section 12 is located below the vertical section 11.

[0042] See also Figure 1 As shown, an air guide structure 5 is provided at one end of the air outlet branch pipe 4 away from the air outlet main pipe 1 , and the air guide structure 5 is used to adjust the air outlet direction of the air outlet branch pipe 4 .

[0043] In this technical solution, the addition of an air guide structure 5 allows the cook to adjust the airflow direction of the outlet branch pipe 4 according to actual needs. Specifically, the air guide structure 5 can be a sweeping blade or a guide plate. To facilitate installation, a bellows 10 can be installed at the end of the outlet branch pipe 4 away from the main outlet pipe 1. The bellows 10 can be shaped like a square, elongated strip, or oval. The sweeping blade or guide plate is installed at the outlet of the bellows 10.

[0044] See also Figure 1 As shown, a first air volume regulating valve 6 is installed on the air outlet main pipe 1 , and the first air volume regulating valve 6 is located between the nozzle 2 and the air outlet branch pipe 4 , and a second air volume regulating valve 7 is installed on the air outlet branch pipe 4 .

[0045] In this embodiment, the first air volume regulating valve 6 can both control the on / off switching of the nozzle 2 and adjust the flow rate of the jet gas ejected from the nozzle 2; the second air volume regulating valve 7 can both control the on / off switching of the air outlet branch pipe 4 and adjust the air volume of the air outlet branch pipe 4. This allows the kitchen air conditioner of the present application to spray the air curtain 3 independently, supply air to the cook independently through the air outlet branch pipe 4, or spray the air curtain 3 and supply air to the cook simultaneously.

[0046] See also Figure 1 As shown, a third air volume regulating valve 8 is further installed on the air outlet main pipe 1 , and the air outlet branch pipe 4 is located between the first air volume regulating valve 6 and the third air volume regulating valve 8 .

[0047] In this technical solution, the third air volume regulating valve 8 can not only control the on-off of the nozzle 2 and the air outlet branch pipe 4, but also adjust the air volume of the entire kitchen air conditioner.

[0048] The present invention also provides a method for controlling a kitchen air conditioner, which is used to control the operation of the aforementioned kitchen air conditioner. The kitchen air conditioner has three operating modes: splash-proof, air supply, and air supply + splash-proof. The control method includes:

[0049] When the kitchen air conditioner operates in anti-splash mode, the first air volume regulating valve 6 and the third air volume regulating valve 8 are controlled to be open, and the second air volume regulating valve 7 is controlled to be closed, so that the nozzle 2 sprays the air curtain 3 to prevent oil splashing, and the air outlet branch pipe 4 does not supply air;

[0050] When the kitchen air conditioner is in air supply mode, the second air volume regulating valve 7 and the third air volume regulating valve 8 are controlled to be open, and the first air volume regulating valve 6 is controlled to be closed. Then, the air outlet branch pipe 4 supplies air to keep the cook comfortable, and the nozzle 2 does not spray the air curtain 3.

[0051] When the kitchen air conditioner operates in the air supply + splash prevention mode, the first air volume regulating valve 6, the second air volume regulating valve 7, and the third air volume regulating valve 8 are all controlled to be open, then the nozzle 2 sprays the air curtain 3 to prevent oil splashing, and the air outlet branch pipe 4 supplies air to keep the cook comfortable.

[0052] It's understood that cooks can freely choose from the three operating modes described above based on the specific conditions of oil and heat throughout the cooking process. For example, in the early stages of cooking, when hot oil splashes significantly, anti-splash mode or air supply + anti-splash mode can be used. In the middle and later stages of cooking, when hot oil splashes less, air supply mode can be considered. Furthermore, the three operating modes of this kitchen air conditioner can be set to high, medium, and low, respectively, to adjust the cooling air volume to meet different user needs.

[0053] It is easy for those skilled in the art to understand that, under the premise of no conflict, the advantageous technical features of the above-mentioned methods can be freely combined and superimposed.

[0054] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention. The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art may make various improvements and variations without departing from the technical principles of the present invention, and such improvements and variations shall also be considered within the scope of protection of the present invention.
