[0002] The kitchen is the main place where people cook, and the quality of the kitchen air environment directly affects people's cooking experience. The kitchen is hot in summer and cold in winter, and there is a demand for cooling and heating. For this reason, people have invented an air - conditioner range hood, which integrates an air - conditioner above the range hood. The air - conditioner part cools the kitchen air in summer and can provide hot air to the kitchen in winter to improve cooking comfort. However, in the related art, some of the temperature - adjusted airflows blown out by the air - conditioner part will be sucked away by the range hood below. The better the smoke - suction performance with a larger air volume, the more temperature - adjusted airflows will be sucked away. The range hood will affect the normal function of the air - conditioner part in adjusting the indoor temperature, making the air - conditioner part unable to achieve its original temperature - adjusting effect well. Summary of the Invention

However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0041] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present invention.

[0042] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0043] In the present invention, unless otherwise clearly specified and defined, terms such as "mounted", "connected", "coupled", "fixed", etc. should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] It should be noted that when an element is referred to as "fixed to" or "disposed on" another element, it may be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only embodiments.

[0046] Referring to Figure 1 , in an embodiment of the present invention, an air-conditioning range hood 100 is provided, which includes a range hood 10 and an air-conditioning device 30. The range hood 10 is used for sucking fumes, and the air-conditioning device 30 is disposed on the range hood 10 and is used for delivering a temperature-adjusted air flow a into the room. For example, in winter, it delivers a hot temperature-adjusted air flow a into the room to increase the kitchen temperature, or in summer, it delivers a cold temperature-adjusted air flow a into the room to lower the kitchen temperature, so as to provide a comfortable kitchen environment for users.

[0047] In some embodiments, the air conditioner range hood 100 further includes an anti-suction device, which includes a blowing member 52. The blowing member 52 is disposed on the range hood 10 and is used to convey an auxiliary air flow b onto the air flow path of the temperature-adjusting air flow a. Among them, the wind path of the combined air flow c after the auxiliary air flow b and the temperature-adjusting air flow a converge is greater than the wind path of the temperature-adjusting air flow a. In this way, by arranging the blowing member 52 on the range hood 10 and conveying the auxiliary air flow b to the temperature-adjusting air flow a through the blowing member 52, the wind path of the combined air flow c formed after the temperature-adjusting air flow a and the auxiliary air flow b converge becomes larger, so as to blow to a place farther away from the range hood 10, preventing the temperature-adjusting air flow a from being sucked away when it is too close to the range hood 10, preventing the range hood 10 from affecting the normal temperature-adjusting effect of the air conditioning device 30, and ensuring that the air conditioning device 30 can achieve its original temperature-adjusting function well.

[0048] In some embodiments, the air outlet of the blowing member 52 is located below the gravity direction of the temperature-adjusting air flow a, and the air outlet direction of the blowing member 52 faces the air flow path of the temperature-adjusting air flow a. In this way, the blowing member 52 blows air from below the temperature-adjusting air flow a, and the auxiliary air flow b provides an anti-gravity acting force for the temperature-adjusting air flow a, enabling the temperature-adjusting air flow a to overcome part of its own gravity and blow to a farther position. The wind path becomes larger after the temperature-adjusting air flow a and the auxiliary air flow b converge, so as to prevent the temperature-adjusting air flow a from being sucked away by the range hood 10.

[0049] Furthermore, the range hood 10 includes a main body 12 and a smoke guide plate 14. The main body 12 has a smoke suction port 121. The smoke guide plate 14 is rotatably disposed on the main body 12 and is used to open and close the smoke suction port 121. For example, when the range hood 10 is performing the oil fume suction operation, the smoke guide plate 14 rotates to open the smoke suction port 121, allowing the oil fume to be sucked into the smoke suction port 121; after the range hood 10 finishes the oil fume suction operation, the smoke guide plate 14 rotates to close the smoke suction port 121. Generally, when the smoke guide plate 14 closes the smoke suction port 121, the smoke guide plate 14 is flush with the outer surface of the range hood 10. When the smoke guide plate 14 opens the smoke suction port 121, the smoke guide plate 14 is inclined relative to the outer surface of the range hood 10, and there is an included angle between the two.

[0050] Moreover, the blowing member 52 is disposed on the outer surface of the smoke guide plate 14 facing away from the smoke suction port 121, and the blowing member 52 can swing as the smoke guide plate 14 rotates. When the range hood 10 starts to work, the smoke guide plate 14 rotates to open the smoke suction port 121, and the blowing member 52 disposed on the smoke guide plate 14 rotates with the smoke guide plate 14 to extend below the temperature-adjusting air flow a, so as to conveniently convey the auxiliary air flow b to the temperature-adjusting air flow a.

[0051] It can be understood that in some other embodiments, the blowing member 52 can also be disposed at other positions of the range hood 10, such as on the main body 12 of the range hood 10. The setting position of the blowing member 52 is not limited herein.

[0052] In some embodiments, when the smoke guide plate 14 opens the smoke suction port 121, the included angle between the smoke guide plate 14 and the plane where the smoke suction port 121 is located is 85 - 100 degrees, and the included angle between the air supply direction of the air supply member 52 and the smoke guide plate 14 is greater than 80 degrees. In this way, when the air conditioner range hood 100 is performing the oil fume suction operation, the smoke guide plate 14 rotates to open the smoke suction port 121. In order to ensure the oil fume suction effect, the included angle between the smoke guide plate 14 and the plane where the smoke suction port 121 is located is controlled between 95 - 100 degrees, for example, controlled to 90 degrees, allowing the oil fume to be fully sucked away. And, the included angle between the air supply direction of the air supply member 52 and the smoke guide plate 14 at this time is greater than 80 degrees, so as to form an auxiliary air flow b that slopes upward, and the auxiliary air flow b is used to push the temperature-adjusting air flow a to a place farther from the range hood 10, so that the wind path of the converging air flow c is greater than the wind path of the temperature-adjusting air flow a.

[0053] In some embodiments, the air supply member 52 is an air curtain machine, and a powerful air flow generated by driving a cross-flow or centrifugal air wheel by a high-speed motor forms an "invisible curtain" as the auxiliary air flow b, which can effectively push the temperature-adjusting air flow a to a position farther from the range hood 10.

[0054] In some embodiments, the anti-suction device further includes a controller. When the first distance between the user and the range hood 10 is greater than the first wind path of the temperature-adjusting air flow a, the controller controls the air supply member 52 to supply the auxiliary air flow b to the temperature-adjusting air flow a. That is to say, when the first wind path of the temperature-adjusting air flow a is small, and the temperature-adjusting air flow a is in front of the user and close to the range hood 10 after being blown out, the controller controls the air supply member 52 to supply the auxiliary air flow b to the temperature-adjusting air flow a to push the temperature-adjusting air flow a to a farther place.

[0055] Further, when the first distance is greater than the first wind path, the controller controls the air supply member 52 to supply air to the temperature-adjusting air flow a in the first direction and form a converging air flow c to push the temperature-adjusting air flow a to a place to be replaced. After that, if the first distance is greater than the second wind path of the converging air flow c, that is, the wind path of the converging air flow c is still small and the converging air flow c can only be blown in front of the user and cannot be blown behind the user, at this time, the controller controls the air supply member 52 to supply air to the temperature-adjusting air flow a in the second direction; wherein, the first direction swings away from the range hood 10 with the air supply member 52 as the fulcrum to form the second direction, that is, the second direction is farther from the range hood 10 than the first direction. If the air supply member 52 supplies air in the second direction, the temperature-adjusting air flow a can be pushed to a position farther from the range hood 10 to further increase the wind path of the converging air flow c and further meet the requirement of preventing the temperature-adjusting air flow a from being sucked away.

[0056] Optionally, when the air supply member 52 supplies air in the first direction, the included angle between the air supply direction of the air supply member 52 and the smoke guide plate 14 is 90 degrees; when the air supply member 52 supplies air in the second direction, the included angle between the air supply direction of the air supply member 52 and the smoke guide plate 14 is 120 degrees.

[0057] Further, after the step of controlling the air supply member 52 to supply air to the temperature-adjusted air flow a in the second direction, if the first distance is still greater than the second air path, that is, the converging air flow c can still only blow in front of the user, the controller controls the air supply member 52 to increase the air supply speed, so as to further increase the thrust of the auxiliary air flow b on the temperature-adjusted air flow a, make the temperature-adjusted air flow a blow to a place farther from the range hood 10, thereby increasing the second air path, making the temperature-adjusted air flow a reach behind the user, far from the range hood 10, and preventing it from being sucked away.

[0058] In some embodiments, the anti-suction device further includes a first sensor 54. The first sensor 54 is disposed at the air outlet of the air-conditioning device 30 for sensing the air outlet angle of the temperature-adjusted air flow a. The controller determines the first air path of the temperature-adjusted air flow a based on the air outlet angle and air outlet speed of the temperature-adjusted air flow a. That is to say, by using the first sensor 54 to detect the air outlet angle of the air-conditioning device 30, and combining the air outlet angle and air outlet speed of the temperature-adjusted air flow a, the first air path can be calculated according to the parabolic movement path of the air flow.

[0059] Specifically, an air outlet grille 32 is provided at the air outlet of the air-conditioning device 30. The first sensor 54 is a rotation sensor and is connected to the air outlet grille 32 for sensing the opening angle of the air outlet grille 32. When the air outlet grille 32 is opened and rotated, the rotation sensor is triggered. The rotation sensor can detect the rotation angle of the air outlet grille 32, and thus can determine the air outlet direction when the temperature-adjusted air flow a blows out through the air outlet grille 32.

[0060] In some embodiments, the anti-suction device further includes a second sensor (not shown in the figure). The second sensor is disposed on the range hood 10 for detecting the first distance between the user and the range hood 10 to obtain the actual position of the user from the range hood 10. Optionally, the second sensor is an infrared sensor.

[0061] In an embodiment of the present invention, a method for supplying air of an air-conditioning range hood 100 is further provided, including the following steps:

[0062] Step S100, using the air-conditioning device 30 disposed on the range hood 10 to supply the temperature-adjusted air flow a into the room;

[0063] Step S300, supplying an auxiliary air flow b to the temperature-adjusted air flow a, so that the auxiliary air flow b and the temperature-adjusted air flow a converge to form a converging air flow c; wherein, the air path of the converging air flow c is greater than the air path of the temperature-adjusted air flow a.

[0064] In this way, an air supply component 52 is provided on the range hood 10, and an auxiliary airflow b is delivered to the temperature-regulating airflow a through the air supply component 52, so that the wind range of the combined airflow c formed after the temperature-regulating airflow a and the auxiliary airflow b merge is increased, so that the combined airflow c is blown to a place farther away from the range hood 10, to prevent the temperature-regulating airflow a from being too close to the range hood 10 and being sucked away, to prevent the range hood 10 from affecting the normal temperature-regulating effect of the air-conditioning device 30, and to ensure that the air-conditioning device 30 can well achieve its original temperature-regulating effect.

[0065] Further, step S300 includes the following steps:

[0066] Step S310, when the first distance between the user and the range hood 10 is greater than the first wind range of the temperature-controlled airflow a, the air supply member 52 is controlled to supply air to the temperature-controlled airflow a in a first direction, and form the convergent airflow c to push the temperature-controlled airflow a to blow toward the replacement location.

[0067] Step S330, if the first distance is greater than the second wind range of the combined airflow c, the air supply member 52 is controlled to supply air to the temperature-adjusting airflow a in a second direction; wherein the first direction swings away from the range hood 10 with the air supply member 52 as a fulcrum to form the second direction. That is, the second direction is further away from the range hood 10 than the first direction. If the air supply member 52 supplies air in the second direction, the temperature-adjusting airflow a can be pushed to a position farther from the range hood 10, so as to further increase the wind range of the combined airflow c, and further meet the requirement of preventing the temperature-adjusting airflow a from being sucked away.

[0068] Optionally, when the air supply member 52 supplies air in a first direction, the angle between the air supply direction of the air supply member 52 and the smoke guide plate 14 is 90 degrees; when the air supply member 52 supplies air in a second direction, the angle between the air supply direction of the air supply member 52 and the smoke guide plate 14 is 120 degrees.

[0069] Step S350, if the first distance is still greater than the second wind range, the controller controls the air supply member 52 to increase the air supply speed. That is, when the combined airflow c can still only blow to the front of the user, the controller controls the air supply member 52 to increase the air supply speed to further increase the thrust of the auxiliary airflow b on the temperature-adjusting airflow a, so that the temperature-adjusting airflow a blows farther from the range hood 10, thereby increasing the second wind range, so that the temperature-adjusting airflow a reaches behind the user, farther from the range hood 10, and prevents it from being sucked away.

[0070] In one embodiment of the present invention, an air supply control device for an air-conditioning range hood is also provided, comprising a temperature-controlled airflow delivery module and an auxiliary airflow delivery module. The temperature-controlled airflow delivery module is used to control the air-conditioning device 30 on the range hood 10 to deliver the temperature-controlled airflow a to the indoor room; the auxiliary airflow delivery module is used to deliver the auxiliary airflow b to the temperature-controlled airflow a, so that the auxiliary airflow b merges with the temperature-controlled airflow a to form a merged airflow c; wherein the wind range of the merged airflow c is greater than the wind range of the temperature-controlled airflow a.

[0071] Thus, an air supply member 52 is provided on the range hood 10. An auxiliary air flow b is supplied to the temperature-adjusting air flow a through the air supply member 52, so that the wind path of the combined air flow c formed after the temperature-adjusting air flow a and the auxiliary air flow b converge becomes longer, and the combined air flow c is blown to a place farther away from the range hood 10, so as to prevent the temperature-adjusting air flow a from being sucked away when it is too close to the range hood 10, prevent the range hood 10 from affecting the normal temperature-adjusting effect of the air-conditioning device 30, and ensure that the air-conditioning device 30 can achieve its original temperature-adjusting function well.

[0072] Furthermore, the auxiliary air flow delivery module includes a first module and a second module. The first module is configured to control the air supply member 52 to supply air to the temperature-adjusting air flow a in a first direction and form the combined air flow c when a first distance between the user and the range hood 10 is greater than a first wind path of the temperature-adjusting air flow a, so as to push the temperature-adjusting air flow a to be blown to a replaced place. The second module is configured to control the air supply member 52 to supply air to the temperature-adjusting air flow a in a second direction when the first distance is greater than a second wind path of the combined air flow c; wherein, the first direction swings away from the range hood 10 with the air supply member 52 as a fulcrum to form the second direction. That is, the second direction is farther away from the range hood 10 than the first direction. If the air supply member 52 supplies air in the second direction, the temperature-adjusting air flow a can be pushed to a position farther away from the range hood 10, so as to further increase the wind path of the combined air flow c and further meet the requirement of preventing the temperature-adjusting air flow a from being sucked away.

[0073] Optionally, when the air supply member 52 supplies air in the first direction, the included angle between the air supply direction of the air supply member 52 and the smoke guide plate 14 is 90 degrees; when the air supply member 52 supplies air in the second direction, the included angle between the air supply direction of the air supply member 52 and the smoke guide plate 14 is 120 degrees.

[0074] Even further, the auxiliary air flow delivery module further includes a third module. The third module is configured to control the air supply member 52 to increase the air supply speed if the first distance is still greater than the second wind path after controlling the air supply member 52 to supply air in the second direction. That is, when the combined air flow c can still only be blown in front of the user, the controller controls the air supply member 52 to increase the air supply speed, so as to further increase the thrust of the auxiliary air flow b on the temperature-adjusting air flow a, blow the temperature-adjusting air flow a to a place farther away from the range hood 10, and then increase the second wind path, so that the temperature-adjusting air flow a reaches behind the user and is far away from the range hood 10, thereby preventing it from being sucked away.

[0075] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0076] The above-described embodiments merely represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
