[0046] Example 1

[0047] This embodiment provides an air outlet structure that can be applied to kitchen air conditioners. Figure 1 This is a schematic diagram of a rotatable air outlet structure provided by an embodiment of the present invention, such as Figure 1 As shown, the air outlet structure includes: a panel 10, a turntable 20, a first driving mechanism 30, an air guide plate 40 and a second driving mechanism 50.

[0048] The panel 10 is provided with an air outlet. A turntable 20 is mounted on the panel 10 and coaxial with the air outlet. The turntable 20 is an annular structure, and its hollow portion matches the air outlet. A first drive mechanism 30 is drivably connected to the turntable 20 and is used to drive the turntable 20 to rotate. An air deflector 40 is located near the air outlet and mounted on the turntable 20, rotating with the turntable 20. A second drive mechanism 50 is drivably connected to the air deflector 40 and is used to drive the air deflector 40 to open and close.

[0049] The air outlet structure of this embodiment can control the opening and closing of the air guide plate 40 by setting the second drive mechanism 50. By setting the turntable 20 and the first drive mechanism 30, the air guide plate 40 can be controlled to rotate together with the turntable 20, thereby changing the air supply direction. The air can be rotated to achieve multi-angle and three-dimensional air supply, which improves the kitchen environment more efficiently and solves the problem in the prior art that the kitchen air conditioner has a single air outlet direction and cannot effectively improve the kitchen environment.

[0050] The turntable 20 rotates along the radial direction on the panel 10, thereby driving the air guide plate 40 to rotate, achieving multi-angle and three-dimensional air supply.

[0051] The first drive mechanism 30 includes a first motor 31 and a first transmission component. The first motor 31 is mounted on the panel 10. The first transmission component is connected to the first motor 31 and to the turntable 20. The first transmission component is used to drive the turntable 20 to rotate under the drive of the first motor 31. In this embodiment, the first motor 31 and the first transmission component can drive the turntable 20 to rotate, thereby achieving rotatability of the air outlet structure.

[0052] The first transmission component can be a gear transmission or a pulley transmission.

[0053] Regarding the gear transmission method, the first transmission component includes a first gear 32 and a second gear 33. The first gear 32 is mounted on the first motor 31, and the second gear 33 is mounted on the turntable 20 and is engaged with the first gear 32. The first motor 31 drives the first gear 32 to rotate, which in turn drives the second gear 33 to rotate, and the turntable 20 rotates along with the second gear 33.

[0054] For the pulley drive method, the first transmission component includes a pulley and a transmission belt. The pulley includes a driving pulley and a driven pulley. The driving pulley is mounted on the first motor 31, and the driven pulley is mounted on the turntable 20. The driving and driven pulleys are connected by a transmission belt. The transmission belt is tightly fitted around the driving and driven pulleys. The first motor 31 drives the driving pulley to rotate, and the friction between the transmission belt and the pulley transmits power, driving the driven pulley to rotate. The turntable 20 rotates with the driven pulley.

[0055] The second drive mechanism 50 includes a second motor 51 and a second transmission component. The second motor 51 is mounted on the turntable 20 via a bracket 52. The second transmission component is connected to the second motor 51 and to the air deflector 40. Driven by the second motor 51, the second transmission component is used to drive the air deflector 40 to open and close. In this embodiment, the second motor 51 and the second transmission component can drive the air deflector 40 to open and close, thereby achieving open and close control of the air outlet structure.

[0056] The second transmission component includes a crankshaft 53 and a connecting rod 54 (also called a wind sweeping connecting rod). One end of the crankshaft 53 is connected to the second motor 51, and the other end is connected to the main body of the connecting rod 54. The main body of the connecting rod 54 is provided with at least one branch, which is connected to each blade of the air deflector 40 in a one-to-one correspondence. The second motor 51 drives the crankshaft 53 and connecting rod 54, which in turn drives the blades of the air deflector 40 to open and close.

[0057] like Figure 2 and Figure 3 As shown, the air outlet structure may further include an outer cover 60, which together with the panel 10 forms a storage space for the above-mentioned turntable 20, the first drive mechanism 30, and the second drive mechanism 50. The outer cover 60 includes a vent 61 connected to the air duct. The airflow driven by the fan is sequentially delivered through the air duct, the vent 61, and the air guide plate 40.

[0058] The first motor 31 can be fixed to the panel 10. The turntable 20 can be fixed axially to the panel 10, allowing radial rotation on the panel 10. The second gear 33 can be fixed to the turntable 20 and rotate along with it. The second motor 51 can be fixed to the turntable 20 via a bracket 52 and rotate along with it. The air deflector 40 can be fixed to the turntable 20. The upper portion of the air deflector 40 is connected to the second motor 51 via a wind sweep connecting rod 54 and a crankshaft 53. The rotation of the second motor 51 drives the crankshaft 53 and wind sweep connecting rod 54 to move, thereby driving the air deflector 40 to open and close.

[0059] The working process of realizing the rotation of the air outlet structure is as follows: the rotation of the first motor 31 drives the rotation of the first gear 32, and then the cooperation between the first gear 32 and the second gear 33 drives the rotation of the turntable 20. Since the air guide plate 40, the bracket 52, the second motor 51, the crankshaft 53 and the wind sweeping connecting rod 54 are all fixed on the turntable 20, they can rotate together with the turntable 20, and realize the overall 360-degree rotation in the horizontal direction as the turntable 20 rotates.

[0060] The opening and closing process of the air guide plate 40 is as follows: the rotation and opening and closing of the air guide plate 40 is achieved by the second motor 51 driving the crankshaft 53 to rotate, and the other end of the crankshaft 53 cooperates with the wind sweeping connecting rod 54, thereby driving the wind sweeping connecting rod 54 to move, and the lower end of the wind sweeping connecting rod 54 is connected to the air guide plate 40, thereby driving the rotation and opening and closing of the air guide plate 40 to realize the change of the wind sweeping angle.

[0061] like Figure 3 As shown, the air guide plate 40 of the air outlet structure is in an open state.

[0062] like Figure 4 As shown, the air guide plate 40 of the air outlet structure is in a closed state.

[0063] like Figure 5 As shown, the air outlet structure only opens the air guide plate 40. At this time, under the action of the air guide plate 40, the air supply direction is to the right.

[0064] like Figure 6 As shown, the air outlet structure rotates horizontally 90 degrees as a whole when the air guide plate 40 opens to a certain angle. At this time, the air supply direction is downward under the action of the air guide plate 40.

[0065] like Figure 7 As shown, the air outlet structure rotates 180 degrees as a whole when the air guide plate 40 opens to a certain angle. At this time, the air supply direction is to the left under the action of the air guide plate 40.

[0066] Example 2

[0067] This embodiment provides a kitchen air conditioner, comprising: at least two air outlet structures as described in the above embodiment, each air outlet structure being independently controlled.

[0068] The kitchen air conditioner of this embodiment includes at least two rotatable air outlet structures. For each air outlet structure, by setting a second drive mechanism 50, the opening and closing of the air guide plate 40 can be controlled. By setting a turntable 20 and a first drive mechanism 30, the air guide plate 40 can be controlled to rotate together with the turntable 20, thereby changing the air supply direction. The air can be rotated to achieve multi-angle and three-dimensional air supply. In addition, the opening and closing and rotation of each air outlet structure can be independently controlled, which is more flexible. Therefore, the kitchen environment can be improved more efficiently, solving the problem that the kitchen air conditioner in the prior art has a single air outlet direction and cannot effectively improve the kitchen environment.

[0069] Preferably, at least two air outlet structures are installed in different areas of the kitchen. Independently controlled air outlet structures can be flexibly arranged according to the layout of the kitchen. Whether it is a narrow and long kitchen or a square kitchen, the position of the air outlet structure can be flexibly arranged to improve the environmental quality in the kitchen in a more efficient way. For example, air outlet structure A is installed in the area near the stove, and air outlet structure B is installed in the area near the sink. Figure 8 As shown, the two independently controlled air outlet structures supply air in different directions, allowing the air supply direction to be adjusted in real time according to the position of the people, so that people in the kitchen can feel cool at any time.

[0070] The kitchen air conditioner may further include an air quality sensor and / or a humidity sensor. Both the air quality sensor and the humidity sensor may be located at the return air outlet of the kitchen air conditioner.

[0071] Air quality sensors are used to detect carbon dioxide and / or carbon monoxide concentrations in the kitchen. By monitoring kitchen air quality, the fresh air function of the kitchen air conditioner can be controlled in a timely manner, effectively improving the kitchen's air quality. In practical applications, carbon dioxide and / or carbon monoxide concentration sensors can be installed.

[0072] Humidity sensors are used to detect humidity in the kitchen. By monitoring the humidity in the kitchen, the dehumidification function of the kitchen air conditioner can be controlled in a timely manner, thereby effectively improving the humidity in the kitchen.

[0073] The above-mentioned kitchen air conditioner may also include: a temperature sensor for detecting the ambient temperature in the kitchen, which serves as a basis for controlling the opening and closing and rotation of the air outlet structure and as a basis for controlling the cooling power of the kitchen air conditioner, so as to take into account both cooling needs and air conditioning energy consumption.

[0074] The above-mentioned kitchen air conditioner may further include: a position sensor for detecting the position of people in the kitchen as a basis for controlling the opening, closing and rotation of the air outlet structure, so that the air supply direction can be adjusted in time according to the position of the people.

[0075] The above-mentioned kitchen air conditioner may further include: a distance sensor for detecting the distance between a person and the air outlet structure, which serves as a basis for controlling the fan speed to accurately meet the user's wind speed requirements.

[0076] Example 3

[0077] This embodiment provides an air outlet control method, which is applied to the kitchen air conditioner described in the above embodiment.

[0078] Figure 9 This is a flow chart of the air outlet control method provided by the embodiment of the present utility model. Figure 9 As shown, the method includes the following steps:

[0079] S901: Detect that someone is in the kitchen and obtain the location of the person in the kitchen.

[0080] S902, controlling the opening, closing and rotation of at least two air outlet structures of the kitchen air conditioner according to the position of the personnel to adjust the air supply direction.

[0081] The kitchen air conditioner of this embodiment includes at least two rotatable air outlet structures, which can independently control the opening and closing and rotation of each air outlet structure, change its air supply direction, and rotate the air to achieve multi-angle and three-dimensional air supply, which is more flexible. The air outlet structure is controlled based on the position of people in the kitchen, so that the air supply direction is adjusted in time with the position of people, truly achieving "wind follows people", and can more efficiently improve the kitchen environment, solving the problem that the kitchen air conditioner in the prior art has a single air outlet direction and cannot efficiently improve the kitchen environment.

[0082] In one embodiment, the opening, closing, and rotation of at least two air outlet structures of the kitchen air conditioner are controlled according to the position of the occupant to adjust the air supply direction, including:

[0083] If there are people in the area where each air outlet structure is located, all air outlet structures will be opened, and each air outlet structure will be controlled to rotate separately so that each air outlet structure can supply air to the area where it is located. By making full use of the independently controlled air outlet structures, people in different positions in the kitchen can feel cool at any time.

[0084] If there is a person in the area where at least one air outlet structure is located and there is no person in the area where at least one air outlet structure is located, the air outlet structure corresponding to the occupied area is opened and the air outlet structure is controlled to rotate so that the air outlet structure supplies air toward the area where it is located, and the opening and closing and rotation of the air outlet structure corresponding to the unoccupied area are controlled according to the ambient temperature in the kitchen. Specifically, the air outlet structure corresponding to the unoccupied area can be closed to reduce air conditioning energy consumption, or the air outlet structure corresponding to the unoccupied area can be used to increase the cooling of the occupied area to improve cooling efficiency;

[0085] If there is no one in the area where each air outlet structure is located, all air outlet structures will be opened and controlled to rotate 360 ​​degrees to achieve multi-angle and three-dimensional air supply, better maintain the overall ambient temperature in the kitchen, and improve the overall environmental quality in the kitchen.

[0086] This embodiment distinguishes between different personnel positions and controls the opening, closing and rotation of the air outlet structure accordingly, which can effectively improve the kitchen environment in a targeted manner. By utilizing the rotatability of the air outlet structure, the air supply direction can be adjusted in time according to the position of the person, truly achieving "the wind follows the person".

[0087] Furthermore, the opening, closing, and rotation of the air outlet structures corresponding to the unoccupied areas are controlled based on the ambient temperature in the kitchen, including: detecting the ambient temperature in the kitchen; if the ambient temperature is less than or equal to the set temperature, indicating that the ambient temperature is suitable, closing the air outlet structures corresponding to the unoccupied areas to reduce the energy consumption of the kitchen air conditioner; if the ambient temperature is greater than the set temperature, indicating that the ambient temperature is too high, opening the air outlet structures corresponding to the unoccupied areas and controlling the air outlet structures to rotate so that they supply air toward occupied areas, thereby increasing the cooling of occupied areas and allowing multiple air outlet structures to supply air in the same direction, thereby improving the cooling efficiency of the kitchen air conditioner, specifically, supplying air toward adjacent occupied areas. The set temperature is a target temperature set by the user based on their own needs.

[0088] This embodiment controls the air outlet structure corresponding to the unmanned area based on the ambient temperature in the kitchen, thereby reducing the energy consumption of the kitchen air conditioner or improving the cooling efficiency of the kitchen air conditioner.

[0089] In one embodiment, after detecting a person in the kitchen and obtaining the person's location within the kitchen, the system further includes: detecting the distance between the person and the air outlet structure corresponding to their area to obtain a reference distance; if the reference distance is greater than a preset distance, the fan speed is increased; if the reference distance is less than or equal to the preset distance, the fan speed is reduced. The preset distance can be set based on actual conditions. This embodiment controls the fan speed based on the distance between the person and the air outlet structure, adjusting the air supply speed of the air outlet structure to ensure more efficient fan operation and improve the efficiency of the kitchen air conditioner.

[0090] Furthermore, each air outlet structure corresponds to the same fan. If there are people in at least two areas, the distance between the people in each area and the air outlet structure corresponding to that area is detected, and the maximum distance is determined as the reference distance. This embodiment controls the fan speed according to the maximum distance, ensuring that the wind speed requirement is met, and avoids the situation where the wind speed cannot be met at a longer distance due to controlling the wind speed according to a shorter distance.

[0091] In one embodiment, the method may further include: detecting the ambient temperature in the kitchen; if the ambient temperature is greater than a set temperature, increasing the cooling power of the kitchen air conditioner; if the ambient temperature is less than or equal to the set temperature, reducing the cooling power of the kitchen air conditioner. This embodiment reduces the cooling power of the kitchen air conditioner while ensuring comfort, thereby saving air conditioning energy consumption.

[0092] The kitchen air conditioner can include a fresh air system. Considering that exhaust gas is generated at any time when the kitchen is in use, the fresh air system is always turned on when the kitchen air conditioner is turned on. The above method also includes:

[0093] Detecting carbon dioxide and / or carbon monoxide concentrations in the kitchen;

[0094] If the carbon dioxide concentration is greater than or equal to the first concentration threshold, it means that the CO2 concentration in the kitchen environment is high and does not meet the requirement of constant indoor air oxygen content, then the operating power of the fresh air system is increased to increase the oxygen content in the kitchen to make the user feel more comfortable;

[0095] If the carbon monoxide concentration is greater than or equal to the second concentration threshold, indicating that the CO concentration in the kitchen environment is high, the operating power of the fresh air system is increased to reduce the CO concentration in the kitchen and reduce the risk of carbon monoxide poisoning. An alarm message is output to remind the user to check the stove status, such as a sound and / or light alarm.

[0096] If the carbon dioxide concentration is less than the first concentration threshold when only the carbon dioxide concentration is detected, or if the carbon monoxide concentration is less than the second concentration threshold when only the carbon monoxide concentration is detected, or if the carbon dioxide concentration is less than the first concentration threshold and the carbon monoxide concentration is less than the second concentration threshold when both the carbon dioxide concentration and the carbon monoxide concentration are detected at the same time, the operating power of the fresh air system is reduced to reduce energy consumption.

[0097] The first concentration threshold and the second concentration threshold can be set according to actual conditions. For example, the first concentration threshold is set to 700 ppm, and the second concentration threshold is set to 50 ppm.

[0098] This embodiment timely controls the operating power of the fresh air system of the kitchen air conditioner based on the carbon dioxide concentration and / or carbon monoxide concentration in the kitchen, can accurately monitor and efficiently improve the air quality in the kitchen, and avoid unnecessary energy consumption.

[0099] The kitchen air conditioner may have a dehumidification function. The method further includes: detecting the ambient humidity in the kitchen; if the ambient humidity is greater than or equal to a humidity threshold, activating the dehumidification function of the kitchen air conditioner; and if the ambient humidity is less than the humidity threshold, deactivating the dehumidification function of the kitchen air conditioner. The humidity threshold can be set based on actual conditions, for example, the humidity threshold can be set to 60%.

[0100] This embodiment timely controls the dehumidification function of the kitchen air conditioner based on the ambient humidity in the kitchen, and can efficiently improve the ambient humidity in the kitchen according to actual needs, so that the humidity in the kitchen is maintained within the humidity range that users feel comfortable, thereby further improving the environmental quality in the kitchen.

[0101] The above-mentioned control of cooling power based on the ambient temperature in the kitchen, control of the operating power of the fresh air system based on the carbon dioxide concentration and / or carbon monoxide concentration in the kitchen, and control of the dehumidification function based on the ambient humidity in the kitchen can be performed when the kitchen air conditioner is turned on, or when the kitchen air conditioner is turned on and someone is detected in the kitchen, so as to save more energy.

[0102] The air outlet control method described above is described below with reference to a specific embodiment. However, it should be noted that this specific embodiment is only intended to better illustrate the present application and does not constitute an undue limitation on the present application. Explanations of terms that are identical or corresponding to those in the above embodiment will not be repeated in this embodiment.

[0103] like Figure 10 As shown, taking the installation of two rotatable air outlet structures in the kitchen as an example, air outlet structure A is installed in the area near the stove, and air outlet structure B is installed in the area near the sink. The air outlet control method of the kitchen air conditioner includes the following steps:

[0104] S1001, the kitchen air conditioner is turned on.

[0105] S1002: Detect that there is someone in the kitchen and detect the person's location.

[0106] S1003, if there is only one person at the stove and no one at the sink, open the air outlet structure A and control the air outlet structure A to rotate so that the air outlet structure A supplies air toward the stove, and control the opening and closing and rotation of the air outlet structure B according to the ambient temperature in the kitchen. Specifically, when the ambient temperature in the kitchen is a suitable temperature (i.e., less than or equal to the set temperature), close the air outlet structure B to reduce the energy consumption of the air conditioner. When the ambient temperature in the kitchen is greater than the set temperature, the air outlet structure B turns toward the stove to increase the cooling in the stove direction, so that the two air outlet structures supply air in the same direction to improve the cooling efficiency of the kitchen air conditioner.

[0107] S1004, if there is only one person at the sink and no one at the stove, open the air outlet structure B and control the air outlet structure B to rotate so that the air outlet structure B supplies air toward the stove, and control the opening and closing and rotation of the air outlet structure A according to the ambient temperature in the kitchen. Specifically, when the ambient temperature in the kitchen is a suitable temperature (that is, less than or equal to the set temperature), close the air outlet structure A to reduce the energy consumption of the air conditioner. When the ambient temperature in the kitchen is greater than the set temperature, the air outlet structure A turns toward the sink to increase the cooling in the direction of the sink, so that the two air outlet structures supply air in the same direction to improve the cooling efficiency of the kitchen air conditioner.

[0108] S1005, if there are people at the stove and people at the sink, open the two air outlet structures, and control the rotation of the two air outlet structures so that the air outlet structure A supplies air toward the stove and the air outlet structure B supplies air toward the sink. Make full use of the two independently controlled air outlet structures so that people at different positions in the kitchen can feel cool at any time.

[0109] S1006: If there is no one at the stove and the sink, open the air outlet structure A and the air outlet structure B, and control the two air outlet structures to rotate 360 ​​degrees to achieve multi-angle three-dimensional air supply, better maintain the overall ambient temperature in the kitchen, and improve the overall environmental quality in the kitchen.

[0110] S1007, detecting the distance between the personnel and the air outlet structure.

[0126] This embodiment provides a novel air outlet configuration and control system for kitchen air conditioners, enabling more efficient improvements to the kitchen environment. By utilizing at least two independently controlled, rotatable air outlet structures, the opening, closing, and rotation of the air outlet structures can be individually controlled while ensuring comfort, achieving three-dimensional air supply. This results in a larger, more three-dimensional air sweep area and seamless air supply. The opening and closing of each air outlet structure can be independently controlled based on the number of people and their positions, providing greater flexibility. These independently controlled air outlet structures can be flexibly arranged to suit the kitchen layout, allowing for flexible placement of the air outlet structures in both narrow and long kitchens and square kitchens, effectively improving the kitchen environment. The rotatability of the air outlet structures allows the airflow direction to be adjusted in real time based on the person's position, truly achieving "the wind follows the person." The fan speed is adjusted based on the distance between the person and the air outlet structure to adjust the air supply speed of the air outlet structure to meet demand. The operating power of the fresh air system can be adjusted in real time based on the air quality within the kitchen, effectively improving the air quality within the kitchen.
