[0079] Example 1

[0080] This embodiment provides an air outlet structure that can be applied to kitchen air conditioners. Figure 1is 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 rotating disk 20, a first driving mechanism 30, an air guide plate 40 and a second driving mechanism 50.

[0081] The panel 10 is provided with an air outlet. The turntable 20 is mounted on the panel 10 and is coaxial with the air outlet. The turntable 20 is an annular structure, and the hollow part of the turntable 20 matches the air outlet. The first driving mechanism 30 is drivingly connected to the turntable 20, and is used to drive the turntable 20 to rotate. The air guide plate 40 is located at the air outlet and is mounted on the turntable 20, and rotates with the turntable 20. The second driving mechanism 50 is drivingly connected to the air guide plate 40, and is used to drive the air guide plate 40 to open and close.

[0083] The turntable 20 rotates along the radial direction on the panel 10, thereby driving the air guide plate 40 to rotate, thereby achieving multi-angle three-dimensional air supply.

[0084] The first driving mechanism 30 includes: a first motor 31 and a first transmission component. The first motor 31 is installed on the panel 10. The first transmission component is connected to the first motor 31 and to the turntable 20, and the first transmission component is used to drive the turntable 20 to rotate under the drive of the first motor 31.

The first gear 32 is mounted on the first motor 31, and the second gear 33 is mounted on the turntable 20 and the second gear 33 is connected with the first gear 32. The first motor 31 drives the first gear 32 to rotate, and the first gear 32 drives the second gear 33 to rotate, and the turntable 20 rotates with the second gear 33.

[0087] For the pulley transmission mode, the first transmission component includes: a pulley and a transmission belt, the pulley includes a driving wheel and a driven wheel, the driving wheel is mounted on the first motor 31, the driven wheel is mounted on the turntable 20, and the driving wheel and the driven wheel are connected by a transmission belt. The transmission belt is tightly sleeved on the driving wheel and the driven wheel, the first motor 31 drives the driving wheel to rotate, and the friction between the transmission belt and the pulley is used to transmit power, driving the driven wheel to rotate, and the turntable 20 rotates with the driven wheel.

[0088] The second driving mechanism 50 includes: a second motor 51 and a second transmission component. The second motor 51 is mounted on the turntable 20 through a bracket 52. The second transmission component is connected to the second motor 51 and to the air guide plate 40, and the second transmission component is used to drive the air guide plate 40 to open and close under the drive of the second motor 51. In this embodiment, the air guide plate 40 can be driven to open and close by the second motor 51 and the second transmission component to realize the opening and closing control of the air outlet structure.

[0089] The second transmission component may include: 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 of the crankshaft 53 is connected to the main body of the connecting rod 54; at least one branch is provided on the main body of the connecting rod 54, which is connected to each blade of the air guide plate 40 in a one-to-one correspondence. The second motor 51 drives the crankshaft 53 and the connecting rod 54 to move, driving the blades of the air guide plate 40 to move, thereby realizing the opening and closing of the blades.

[0090] 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 receiving space for placing the above-mentioned turntable 20, the first driving mechanism 30 and the second driving mechanism 50. The outer cover 60 includes a vent 61 connected to the air duct, and the airflow driven by the fan is sent out through the air duct, the vent 61 and the air guide plate 40 in sequence.

[0091] The first motor 31 can be fixed on the panel 10. The axial direction of the turntable 20 can be fixed on the panel 10, and the turntable 20 can rotate in the radial direction on the panel 10. The second gear 33 can be fixed on the turntable 20 and rotate with the turntable 20. The second motor 51 can be fixed on the turntable 20 through the bracket 52 and rotate with the turntable 20. The wind guide plate 40 can be fixed on the turntable 20, and the top of the wind guide plate 40 is connected to the second motor 51 through the wind sweeping connecting rod 54 and the crankshaft 53. The rotation of the second motor 51 can drive the crankshaft 53 and the wind sweeping connecting rod 54 to move, thereby driving the wind guide plate 40 to open and close.

[0092] 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 with the rotation of the turntable 20.

[0094] like Figure 3 As shown, the air guide plate 40 of the air outlet structure is in an open state.

[0095] like Figure 4 As shown, the air guide plate 40 of the air outlet structure is in a closed state.

[0096] like Figure 5 As shown, the air outlet structure only opens the air guide plate 40, and at this time, the air supply direction is to the right under the action of the air guide plate 40.

[0097] like Figure 6 As shown, the air outlet structure is rotated 90 degrees horizontally as a whole when the air guide plate 40 opens a certain angle. At this time, the air supply direction is downward under the action of the air guide plate 40.

[0098] like Figure 7 As shown, the air outlet structure rotates 180 degrees as a whole when the air guide plate 40 opens a certain angle. At this time, the air supply direction is to the left under the action of the air guide plate 40.

[0099] Example 2

[0100] The present embodiment provides a kitchen air conditioner, comprising: at least two air outlet structures as described in the above embodiments, each air outlet structure being independently controlled.

[0101] The kitchen air conditioner of the present embodiment includes at least two rotatable air outlet structures. For each air outlet structure, by setting a second driving mechanism 50, the opening and closing of the air guide plate 40 can be controlled. By setting a turntable 20 and a first driving 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 three-dimensional air supply, and 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, which solves the problem that the kitchen air conditioner in the prior art has a single air outlet direction and cannot efficiently improve the kitchen environment.

[0102] 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 positions of the air outlet structures 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 an area near the stove, and air outlet structure B is installed in an area near the sink. Figure 8 As shown, two independently controlled air outlet structures supply air in different directions respectively, so that the air supply direction can be adjusted in real time according to the position of the personnel, so that the personnel in the kitchen can feel cool at any time.

[0103] The above kitchen air conditioner may further include: an air quality sensor and / or a humidity sensor. The air quality sensor and the humidity sensor may both be located at the return air outlet of the kitchen air conditioner.

[0104] The air quality sensor is used to detect the carbon dioxide concentration and / or carbon monoxide concentration in the kitchen. By monitoring the air quality in the kitchen, the fresh air function of the kitchen air conditioner can be controlled in time, thereby effectively improving the air quality in the kitchen. In practical applications, a carbon dioxide concentration sensor and / or a carbon monoxide concentration sensor can be set.

[0105] The humidity sensor is used to detect the ambient humidity in the kitchen. By monitoring the ambient humidity in the kitchen, the dehumidification function of the kitchen air conditioner can be controlled in time, thereby effectively improving the humidity in the kitchen.

[0106] The above-mentioned kitchen air conditioner may also include: a temperature sensor for detecting the ambient temperature in the kitchen as a basis for controlling the opening and closing and rotation of the air outlet structure and as a basis for controlling the refrigeration power of the kitchen air conditioner to take into account both refrigeration requirements and air conditioning energy consumption.

[0107] The above-mentioned kitchen air conditioner may also 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.

[0108] The above-mentioned kitchen air conditioner may also include: a distance sensor for detecting the distance between a person and the air outlet structure as a basis for controlling the fan speed to accurately meet the user's wind speed requirements.

[0109] Example 3

[0110] This embodiment provides an air outlet control method, which is applied to the kitchen air conditioner described in the above embodiment.

[0111] Fig. 9 is a flow chart of the air outlet control method provided by an embodiment of the present invention, such as Fig. 9As shown, the method comprises the following steps:

[0112] S901, detecting that there is someone in the kitchen and obtaining the location of the person in the kitchen.

[0113] S902, controlling the opening, closing and rotation of at least two air outlet structures of the kitchen air conditioner according to the positions of the personnel to adjust the air supply direction.

[0114] 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 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 can be 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.

[0115] In one embodiment, the opening and closing and rotation of at least two air outlet structures of the kitchen air conditioner are controlled according to the position of the personnel to adjust the air supply direction, including:

[0116] If there are people in the area where each air outlet structure is located, all the air outlet structures are opened, and each air outlet structure is controlled to rotate separately, so that each air outlet structure supplies air to the area where it is located, making full use of the independently controlled air outlet structures, so that people in different positions in the kitchen can feel cool at any time;

[0117] If there are people in the area where at least one air outlet structure is located and there are no people in the area where at least one air outlet structure is located, the air outlet structure corresponding to the area where there are people 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 unmanned area are controlled according to the ambient temperature in the kitchen. Specifically, the air outlet structure corresponding to the unmanned area can be closed to reduce air conditioning energy consumption, or the air outlet structure corresponding to the unmanned area can be used to increase the cooling of the manned area to improve the cooling efficiency;

[0118] 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 three-dimensional air supply, better maintain the overall ambient temperature in the kitchen, and improve the overall environmental quality in the kitchen.

[0119] This implementation distinguishes between different personnel positions and controls the opening, closing and rotation of the air outlet structure accordingly, which can improve the kitchen environment in a targeted and efficient manner. The rotatability of the air outlet structure is utilized to adjust the air supply direction in a timely manner according to the position of the person, truly achieving "the wind follows the person".

[0120] Furthermore, the opening and closing and rotation of the air outlet structure corresponding to the unmanned area are controlled according to 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, then the air outlet structure corresponding to the unmanned area is closed 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 high, then the air outlet structure corresponding to the unmanned area is opened, and the air outlet structure is controlled to rotate so that the air outlet structure can send air toward the manned area, increase the cooling of the manned area, and let multiple air outlet structures send air in the same direction, improve the cooling efficiency of the kitchen air conditioner, and specifically send air toward the adjacent manned area. Among them, the set temperature is the target temperature set by the user according to his own needs.

[0121] 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.

[0122] In one embodiment, after detecting that there is someone in the kitchen and obtaining the position of the person in the kitchen, it also includes: detecting the distance between the person and the air outlet structure corresponding to the area where he is located 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 according to actual conditions. This embodiment controls the fan speed based on the distance between the person and the air outlet structure, adjusts the air supply speed of the air outlet structure, ensures that the fan operates in a more efficient manner, and improves the operating efficiency of the kitchen air conditioner.

[0123] Furthermore, each air outlet structure corresponds to the same fan, and if there are people in at least two areas, the distance between the people in each area and the air outlet structure corresponding to the area is detected respectively, and the maximum distance is determined as the reference distance. This embodiment controls the fan speed according to the farthest distance, which can ensure that the wind speed requirement is met and avoid the situation where the wind speed requirement at a long distance cannot be met due to controlling the wind speed according to a shorter distance.

[0124] In one embodiment, the method may further include: detecting the ambient temperature in the kitchen; if the ambient temperature is greater than the 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, so as to save air conditioning energy consumption.

[0125] The kitchen air conditioner may 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:

[0126] Detect carbon dioxide and / or carbon monoxide concentrations in the kitchen;

[0127] 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 oxygen content in the indoor air, then the operating power of the fresh air system is increased to increase the oxygen content in the kitchen, so that the user feels more comfortable;

[0128] 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, thereby reducing the risk of carbon monoxide poisoning, and an alarm message is output to remind the user to check the stove status, such as sound and / or light alarm, etc.;

[0129] 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 simultaneously, the operating power of the fresh air system is reduced to reduce energy consumption.

[0130] 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.

[0131] 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.

[0132] The kitchen air conditioner may have a dehumidification function, and the above method further includes: detecting the ambient humidity in the kitchen; if the ambient humidity is greater than or equal to a humidity threshold, turning on the dehumidification function of the kitchen air conditioner; if the ambient humidity is less than the humidity threshold, turning off the dehumidification function of the kitchen air conditioner. The humidity threshold may be set according to actual conditions, for example, the humidity threshold is set to 60%.

[0133] 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.

[0134] The above-mentioned control of the refrigeration power based on the ambient temperature in the kitchen, the 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 the 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.

[0135] The above-mentioned air outlet control method is described below in conjunction with a specific embodiment. However, it is worth noting that this specific embodiment is only for better illustrating the present application and does not constitute an improper limitation on the present application.

[0136] like Fig.10 As shown, taking the installation of two rotatable air outlet structures in the kitchen as an example, the air outlet structure A is installed in the area near the stove, and the 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:

[0137] S1001, kitchen air conditioner turned on.

[0138] S1002, detecting that there is someone in the kitchen and detecting the person's location.

[0139] 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 in the direction of 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 to the direction of the stove to increase the cooling in the direction of the stove, so that the two air outlet structures supply air in the same direction to improve the cooling efficiency of the kitchen air conditioner.

[0140] 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 in the direction of 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 (i.e., 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 to the direction of 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.

[0141] S1005, if there are people at the stove and people at the sink, open the two air outlet structures, and control the two air outlet structures to rotate so that air outlet structure A supplies air toward the stove, and air outlet structure B supplies air toward the sink, making 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.

[0142] 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.

[0143] S1007, detecting the distance between the personnel and the air outlet structure.

[0144] S1008, adjusting the fan speed according to the detected distance.

[0145] S1009, detecting the ambient temperature T in the kitchen.

[0146] S1010, determine whether T≤26°C is satisfied, if so, proceed to S1012, if not, proceed to S1011.

[0147] S1011, increase the operating power of the refrigeration system.

[0148] S1012, reduce the operating power of the refrigeration system.

[0149] S1013, detecting the CO2 concentration, CO concentration and ambient humidity in the kitchen.

[0150] S1014, determine whether CO2 concentration < C1 is satisfied, if yes, proceed to S1016, if no, proceed to S1015. C1 represents the first concentration threshold.

[0151] S1015, improve the operating power of the fresh air system.

[0152] S1016, determine whether the CO concentration < C2 is satisfied, if so, proceed to S1018, if not, proceed to S1017. C2 represents the second concentration threshold.

[0153] S1017, increases the operating power of the fresh air system, and the alarm sounds to remind personnel to check the stove condition.

[0154] S1018, reduce the operating power of the fresh air system.

[0155] S1019, determine whether the humidity is less than C3, if so, proceed to S1021, if not, proceed to S1020. C3 represents the humidity threshold.

[0156] S1020, turn on the dehumidification function of the kitchen air conditioner.

[0157] S1021, turn off the dehumidification function of the kitchen air conditioner.

[0158] The above steps S1009 to S1012 can be directly executed when the kitchen air conditioner is turned on, or can be executed when the kitchen air conditioner is turned on and there is someone in the kitchen.

[0159] This embodiment provides a new type of kitchen air conditioning air outlet form and its control, which can improve the kitchen environment more efficiently. Through at least two independently controlled rotatable air outlet structures, under the premise of ensuring comfort, the opening and closing and rotation of the air outlet structure are independently controlled to achieve three-dimensional air supply, and the air sweeping area is larger and more three-dimensional, so that there is no dead angle for air supply. The opening and closing of each air outlet structure can be independently controlled according to the number of people and the position of the people, which is more flexible; such 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. Based on the position of the personnel, the rotatability of the air outlet structure is used to make the air outlet direction follow the position of the person and adjust it in time, so as to truly achieve "the wind follows the person". The fan speed is adjusted based on the distance between the person and the air outlet structure to change the air supply speed of the air outlet structure to meet the needs. Based on the air quality in the kitchen, the operating power of the fresh air system can be adjusted in time to achieve efficient improvement of the air quality in the kitchen.
