DETAILED DESCRIPTION

[0045] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0046] Considering that air conditioners (such as air conditioners with separate upper and lower air guides) have many air supply modes, the operation is cumbersome and inconvenient for users. For example, the left and right air guide components of conventional air conditioners have only two modes: on and off, while the left and right air guide blades of separate upper and lower air guide air conditioners have four air guide modes: upper and lower closed, upper open and lower closed, upper closed and lower open, and upper and lower open. With the addition of upper and lower air guide components, there are more air guide modes; with so many separate air guide blade control modes, users have to switch cumbersomely and inconveniently.

[0047] Moreover, a single air supply mode cannot take into account both temperature comfort and wind comfort. For example, taking the cooling mode as an example, when the air conditioner is just turned on, in order to increase the indoor air disturbance and improve the heat exchange efficiency, the user usually needs to turn on the air guide component. At this time, the indoor temperature is relatively high, and the cold air blown by the air conditioner will not cause obvious discomfort to the user. However, after the air conditioner has been running for a period of time, the indoor temperature is close to the set temperature. At this time, the operation of the air guide blades will blow cold air to the user, causing discomfort. Therefore, it is necessary to adjust the air guide blades and switch the air guide mode so that the cold air cannot blow directly to the user. In other words, as the air conditioner is running, a single air guide mode cannot take into account both the user's temperature comfort and wind comfort.

[0048] Therefore, the scheme of the present invention proposes a control method of an air conditioner, specifically, an automatic air supply control method of an air conditioner with upper and lower separate air guides, which adjusts the air supply mode of the air conditioner according to the comparison between the ambient temperature of the upper and lower parts of the room and the set temperature, and the difference between the air inlet temperature at different air inlet angles and the average temperature, so as to facilitate user use and improve the user's comfort experience. The main purpose of the scheme of the present invention is not only to facilitate user operation, but also to achieve high-precision overall room temperature control, to prevent excessive local temperature differences in the room, and to greatly improve the comfort of the air conditioner.

[0049] According to an embodiment of the present invention, a method for controlling an air conditioner is provided. Figure 1 A flow chart of an embodiment of the method of the present invention is shown. The control method of the air conditioner is applied to the air supply control of an air conditioner with upper and lower air guides, the air conditioner has an air inlet and an air outlet, the air outlet has two or more air guide components, the two or more air guide components of the air outlet can operate in different air supply modes, and the compressor of the air conditioner can operate at different frequencies; m temperature detection devices are correspondingly provided at the m air inlet angles at the upper part of the air inlet, n temperature detection devices are correspondingly provided at the n air inlet angles at the lower part of the air inlet, and p temperature detection devices are correspondingly provided at the p air inlet angles in the middle part of the air inlet, m, n, and p are all positive integers, preferably m=5, n=5, and p=3. Among them, for the p temperature detection devices, P can be considered to be 3; but with the addition of a temperature detection device horizontally distributed in the upper part and a temperature detection device horizontally distributed in the lower part, p can actually be considered to be 5. In the scheme of the present invention, Figure 1 As shown, the air conditioner control method includes: steps S110 to S140.

[0050] At step S110, the temperature detected by each of the m temperature detection devices is obtained to obtain m upper air inlet temperatures; the temperature detected by each of the n temperature detection devices is obtained to obtain n lower air inlet temperatures; the temperature detected by each of the p temperature detection devices is obtained to obtain p middle air inlet temperatures; and the set temperature under the current operating mode of the air conditioner is obtained; wherein the current operating mode of the air conditioner includes: a cooling mode of the air conditioner or a heating mode of the air conditioner.

[0051] In step S120, the average value of the m upper air inlet temperatures is determined and recorded as the upper average air inlet temperature, such as Fig.12 The current temperature of the upper part of the indoor unit air inlet is shown. Fig.13 The upper air inlet temperature shown in FIG. 1 is used to determine the average value of the n lower air inlet temperatures, recorded as the lower average air inlet temperature, such as Fig.12 The current temperature at the lower part of the indoor unit air inlet is shown. Fig.13 and determine the average of the p middle air inlet temperatures, recorded as the middle average air inlet temperature, such as Fig.12 The current temperature in the middle of the indoor unit air inlet is shown. Fig.13 The middle air inlet temperature is shown.

[0052] At step S130, when the air conditioner is turned on and the current operating mode of the air conditioner is run, the air supply mode of the two or more air guide components of the air outlet is controlled, the frequency of the compressor of the air conditioner is controlled, and based on the set temperature in the current operating mode of the air conditioner, combined with at least one of the upper average air inlet temperature and the lower average air inlet temperature, the air supply mode of the two or more air guide components of the air outlet and the frequency of the compressor of the air conditioner are adjusted.

[0053] At step S140, when the air conditioner is operated in an air supply mode of the two or more air guide components of the air outlet, at least one of the operating speed and the residence time of the two or more air guide components of the air outlet at the corresponding positions is adjusted in combination with at least one of the m upper air inlet temperatures and the upper average air inlet temperature, the n lower air inlet temperatures and the lower average air inlet temperature, and the p middle air inlet temperatures and the middle average air inlet temperature.

[0054] The scheme of the present invention proposes an automatic air supply control scheme for an air conditioner with upper and lower separate air guides. The automatic air supply scheme is adopted to adjust the air supply mode of the air conditioner according to the comparison between the ambient temperature and the set temperature of the upper and lower parts of the room, and the difference between the air inlet temperature and the average temperature at different air inlet angles. Not only can rapid temperature rise and drop be achieved, but also high-precision temperature control can be maintained and the discomfort caused by wind sensation can be reduced, thereby greatly improving the comfort of the air conditioner.

[0055] In some embodiments, the two or more air guide components of the air outlet include: an upper left and right air guide component located at the upper part of the air outlet, a lower left and right air guide component located at the lower part of the air outlet, and an upper and lower air guide component located between the upper part and the lower part of the air outlet. The air supply mode of the two or more air guide components of the air outlet includes: at least one of: a first mode in the current operating mode of the air conditioner, a second mode in the current operating mode of the air conditioner, and a third mode in the current operating mode of the air conditioner.

[0056] Among them, the first mode in the current operation mode of the air conditioner is: the upper left and right air guide components and the lower left and right air guide components operate alternately, and the upper and lower air guide components operate independently; for example: mode A in cooling mode, or mode D in heating mode.

[0057] The second mode under the current operation mode of the air conditioner is: the upper left and right air guide components are running, the lower left and right air guide components are stopped and are in the minimum air outlet position, and the upper and lower air guide components are fixed to guide air upward; for example: mode B in cooling mode, or mode E in heating mode.

[0058] The third mode under the current operating mode of the air conditioner is: the upper left and right air guide components and the lower left and right air guide components both stop running and are in the minimum air outlet position, and the upper and lower air guide components are fixed to guide air upward; for example: mode C under cooling mode, or mode F under heating mode.

[0059] Fig. 9 It is a structural schematic diagram of an air guide structure with upper and lower parts for guiding air. Fig. 9 The invention comprises two upper and lower left and right wind guide components (such as upper left and right wind sweeping components 3 and lower left and right wind sweeping components 4), a driving component (such as driving component 2) and an air outlet frame (such as air outlet frame 1). The left and right wind guide components and the driving component are connected to the air outlet frame. The driving component can simultaneously control the upper and lower left and right wind guide components, so that the upper and lower left and right wind guide components can run alternately or independently. Fig. 9 In the example shown, the left and right air guide blades are divided into two upper and lower parts.

[0060] exist Fig.11 In the control scheme under the cooling operation mode shown, there are three air-conditioning air guide components, namely the upper left and right air guide components, the lower left and right air guide components and the upper and lower air guide components. The three air supply methods are described as follows: A method air supply, B method air supply, and C method air supply.

[0061] exist Fig.12In the control scheme under the heating operation mode shown, three air supply modes are described as follows: D mode air supply, E mode air supply, and F mode air supply.

[0062] In the scheme of the present invention, asynchronous air guiding: the upper and lower left and right air guiding components move asynchronously and staggeredly to increase indoor air disturbance and promote temperature exchange. Single-sided air guiding: only one of the upper and lower left and right air guiding components is in operation, and the other left and right air guiding components are closed or fixed in a certain position, so that only the upper or lower part of the air conditioner performs left and right air guiding operation. The automatic air supply control scheme of the upper and lower separated air guiding air conditioner is adopted. According to the comparison between the ambient temperature of the upper and lower parts of the room and the set temperature, the air supply mode of the air conditioner is adjusted, which can achieve rapid temperature rise and temperature drop, perform high-precision temperature control and reduce the discomfort caused by the wind, improve the comfort of the air conditioner, and solve the problems of complex adjustment of the air supply mode and wind discomfort of the upper and lower separated air guiding air conditioner.

[0063] In some embodiments, the m temperature detection devices are uniformly arranged circumferentially along the air inlet direction of the upper part of the air inlet in the air inlet area of ​​the upper part of the air inlet; the n temperature detection devices are uniformly arranged circumferentially along the air inlet direction of the lower part of the air inlet in the air inlet area of ​​the lower part of the air inlet; the p temperature detection devices are vertically distributed in the air inlet area of ​​the middle part of the air inlet along the middle part of the air inlet.

[0064] Fig.10 The diagram is a distribution diagram of the air conditioner temperature detector of the present invention, wherein (a) is a diagram of the temperature detection device distributed along the horizontal circumferential direction of the air inlet, and (b) is a diagram of the temperature detection device distributed along the middle of the air inlet vertically. In (a), there are five horizontally distributed temperature detection devices in the upper part and five horizontally distributed temperature detection devices in the lower part. Fig.10 As shown, the air conditioner has an indoor heat exchanger 6, an indoor fan 7, upper and lower air guide components 8, left and right air guide components 9, and an indoor air inlet area 10. Five temperature detectors (such as temperature sensor 5) are evenly distributed along the air inlet area at the upper and lower parts of the air conditioner, and five temperature detectors are also evenly distributed along the vertical direction in the middle of the air inlet (the top and bottom two temperature detectors are shared with the upper and lower temperature detectors of the air conditioner). There are thirteen temperature detectors in total. The average temperature detected by the five upper temperature detection devices represents the upper temperature of the indoor air inlet, the average temperature detected by the five lower temperature detection devices represents the lower temperature of the indoor air inlet, and the average temperature detected by the five temperature detection devices in the vertical direction in the middle of the air inlet represents the middle temperature of the air inlet. Fig.10 In the example shown, the operation of different air guide plates can be adjusted according to different temperature differences by using multiple air inlet temperature detection devices.

[0065] In the scheme of the present invention, a total of thirteen temperature detection devices are arranged at the air inlet of the air conditioner, namely, five temperature detection devices distributed along the horizontal circumference of the upper part of the air inlet, five temperature detection devices distributed along the horizontal circumference of the lower part of the air inlet, and five temperature detection devices distributed along the vertical direction of the air inlet in the middle of the air inlet, two of which are repeated, so there are a total of thirteen temperature detection devices. The three groups of temperature detection devices are evenly placed. In the scheme of the present invention, the air inlet angle is only a rough statement. The essence is that different temperature detection devices use different air guide plates with different wind sweeping ranges and wind sweeping angles. Among them, the five temperature detection devices evenly distributed along the horizontal circumference of the upper part of the air inlet correspond to the upper left and right air guide plates; the five temperature detection devices evenly distributed along the horizontal circumference of the lower part of the air inlet correspond to the lower left and right air guide plates, and the five temperature detection devices evenly distributed along the vertical direction in the middle of the air inlet correspond to the upper and lower air guide plates.

[0066] In the scheme of the present invention, there are three average temperatures, namely, the upper temperature of the air inlet representing the upper temperature of the room, the lower temperature of the air inlet representing the lower temperature of the room, and the middle temperature of the air inlet representing the air inlet temperature. Set temperature: the target temperature set by the air conditioner. Upper air inlet temperature: the indoor ambient temperature above the air inlet of the air conditioner indoor unit is represented by the average value of the five temperature detection devices located at the upper part of the air inlet. Lower air inlet temperature: the indoor ambient temperature below the air inlet of the air conditioner indoor unit is represented by the average value of the five temperature detection devices located at the lower part of the air inlet. Middle air inlet temperature: represented by the average value of the five temperature detection devices located in the middle of the air inlet and distributed in the vertical direction.

[0067] The air conditioner corresponding to the scheme of the present invention is a variable frequency air conditioner with upper and lower parts for air guiding, and there are two upper and lower left and right air guiding components and an upper and lower air guiding component connecting the upper and lower parts of the air outlet at the air outlet, and there are more than ten temperature detection devices in the air conditioner, which are respectively located at the upper part of the air inlet and the lower part of the air inlet, and are used to detect the upper ambient temperature of the room and the lower ambient temperature of the room, wherein the average temperature detected by the five upper temperature detection devices represents the upper temperature of the air inlet of the indoor unit, and the average temperature detected by the five lower temperature detection devices represents the lower temperature of the air inlet of the indoor unit. The air conditioner can be a cabinet unit or other hanging units, window units, etc. with upper and lower air guiding components. Among them, the five temperature detection devices are evenly distributed along the horizontal circumference of the air inlet, and the five temperature detection devices are because on the one hand, they can accurately identify the temperature at different angles on the left and right sides of the room, and on the other hand, they can also save costs. Because if there are too few temperature detection devices, such as two or three, the temperature difference at multiple angles cannot be represented, and it is impossible to achieve directional temperature control at multiple angles, and if there are too many, it will be too wasteful, which will increase the cost on the one hand, and on the other hand, the indoor temperature difference is relatively rough, and there will not be obvious temperature differences every few degrees, so too many temperature detection devices are not needed. Therefore, setting five temperature detection devices is a more appropriate number of temperature detection devices.

[0068] In some embodiments, step S130 adjusts the air supply mode of the two or more air guide components of the air outlet and the frequency of the compressor of the air conditioner based on the set temperature in the current operating mode of the air conditioner and in combination with at least one of the upper average air inlet temperature and the lower average air inlet temperature, including: a first process of adjusting the air supply mode of the two or more air guide components of the air outlet and the frequency of the compressor.

[0069] Combine the following Figure 2 The flowchart of an embodiment of the first process of adjusting the air supply mode of the two or more air guide components of the air outlet and the frequency of the compressor in the method of the present invention is shown, and the specific process of the first process of adjusting the air supply mode of the two or more air guide components of the air outlet and the frequency of the compressor in step S130 is further explained, including: step S210 to step S240.

[0070] Step S210, controlling the air supply mode of the two or more air guide components of the air outlet to be the first mode in the current operating mode of the air conditioner, and controlling the frequency of the compressor to be the first frequency set in the current operating mode of the air conditioner.

[0071] Step S220, for the first time, determines whether the absolute value of the difference between the lower average air inlet temperature and the set temperature in the current operating mode of the air conditioner is less than or equal to the set first temperature threshold; wherein, the set first frequency is such as the frequency A1 in the cooling mode or the frequency D1 in the heating mode, and the set first temperature threshold is the set threshold T1.

[0072] Step S230, if it is determined for the first time that the absolute value of the difference between the lower average air inlet temperature and the set temperature in the current operating mode of the air conditioner is greater than the set first temperature threshold, then return to continue controlling the air supply mode of the two or more air guide components of the air outlet to be the first mode in the current operating mode of the air conditioner, and continue to control the frequency of the compressor to be the first frequency set in the current operating mode of the air conditioner.

[0073] Step S240, if it is determined for the first time that the absolute value of the difference between the lower average air inlet temperature and the set temperature in the current operating mode of the air conditioner is less than or equal to the set first temperature threshold, then the air supply mode of the two or more air guide components of the air outlet is controlled to be the second mode in the current operating mode of the air conditioner, and the frequency of the compressor is controlled to be the second frequency set in the current operating mode of the air conditioner; wherein the set second frequency is less than the set first frequency, such as the frequency B1 in the cooling mode or the frequency E1 in the heating mode.

[0074] In the scheme of the present invention, by adjusting the air supply mode of more than two air guide components of the air outlet and the first process of the frequency of the compressor, a variety of air supply modes are alternately controlled according to the difference between the upper and lower temperatures of the room and the set temperature, so as to achieve a long-term temperature control effect with low temperature fluctuations. When the ambient temperature is close to the set temperature, the problem of wind discomfort can be improved; different maximum operating frequencies of the compressor are set to correspond to different room temperature differences to achieve energy-saving effects.

[0077] Step S310, when it is determined for the first time that the absolute value of the difference between the lower average air inlet temperature and the set temperature in the current operating mode of the air conditioner is less than or equal to the set first temperature threshold, after controlling the air supply mode of more than two air guide components of the air outlet to be the second mode in the current operating mode of the air conditioner, and controlling the frequency of the compressor to be the second frequency set in the current operating mode of the air conditioner, it is determined for the first time whether the absolute value of the difference between the upper average air inlet temperature and the set temperature in the current operating mode of the air conditioner is less than or equal to the set second temperature threshold.

[0078] Step S320, if it is determined for the first time that the absolute value of the difference between the upper average air inlet temperature and the set temperature in the current operating mode of the air conditioner is greater than the set second temperature threshold, then it is determined for the second time whether the absolute value of the difference between the lower average air inlet temperature and the set temperature in the current operating mode of the air conditioner is less than or equal to the set first temperature threshold.

[0079] Step S330, if it is determined for the second time that the absolute value of the difference between the lower average air inlet temperature and the set temperature in the current operating mode of the air conditioner is greater than the set first temperature threshold, then return to continue controlling the air supply mode of the two or more air guide components of the air outlet to be the first mode in the current operating mode of the air conditioner, and continue to control the frequency of the compressor to be the first frequency set in the current operating mode of the air conditioner.

[0080] Step S340, if it is determined for the second time that the absolute value of the difference between the lower average air inlet temperature and the set temperature in the current operating mode of the air conditioner is less than or equal to the set first temperature threshold, then return to continue controlling the air supply mode of the two or more air guide components of the air outlet to be the second mode in the current operating mode of the air conditioner, and continue to control the frequency of the compressor to be the second frequency set in the current operating mode of the air conditioner.

[0081] In the scheme of the present invention, by adjusting the air supply mode of more than two air guide components of the air outlet and the second process of the frequency of the compressor, a variety of air supply modes are alternately controlled according to the difference between the upper and lower temperatures of the room and the set temperature, so as to achieve a long-term temperature control effect with low temperature fluctuations. When the ambient temperature is close to the set temperature, the problem of wind discomfort can be improved; different maximum operating frequencies of the compressor are set to correspond to different room temperature differences to achieve energy-saving effects.

[0082] In some embodiments, step S130 adjusts the air supply mode of the two or more air guide components of the air outlet and the frequency of the compressor of the air conditioner based on the set temperature in the current operating mode of the air conditioner and in combination with at least one of the upper average air inlet temperature and the lower average air inlet temperature, and also includes: a third process of adjusting the air supply mode of the two or more air guide components of the air outlet and the frequency of the compressor.

[0083] Combine the following Figure 4 The flowchart of an embodiment of the third process of adjusting the air supply mode of the two or more air guide components of the air outlet and the frequency of the compressor in the method of the present invention is shown, which further illustrates the specific process of the third process of adjusting the air supply mode of the two or more air guide components of the air outlet and the frequency of the compressor in step S130, including: step S410 to step S450.

[0084] Step S410, if it is determined for the first time that the absolute value of the difference between the upper average air inlet temperature and the set temperature in the current operating mode of the air conditioner is less than or equal to the set second temperature threshold, then the air supply mode of the two or more air guide components of the air outlet is controlled to be the third mode in the current operating mode of the air conditioner, and the frequency of the compressor is controlled to be the third frequency set in the current operating mode of the air conditioner; wherein the set third frequency is less than the set second frequency, such as the frequency C1 in the cooling mode or the frequency F1 in the heating mode.

[0085] Step S420, first determine whether the absolute value of the difference between the lower average air inlet temperature and the set temperature in the current operating mode of the air conditioner is less than or equal to the set third temperature threshold; wherein the set third temperature threshold is such as the set threshold T3.

[0086] Step S430, if it is determined for the first time that the absolute value of the difference between the lower average air inlet temperature and the set temperature in the current operating mode of the air conditioner is greater than the set third temperature threshold, then it is determined for the second time whether the absolute value of the difference between the upper average air inlet temperature and the set temperature in the current operating mode of the air conditioner is less than or equal to the set second temperature threshold; wherein, the set first temperature threshold is greater than the set second temperature threshold, the set second temperature threshold is greater than the set third temperature threshold, and the set second temperature threshold is such as the set threshold T2.

[0087] Step S440, if it is determined for the second time that the absolute value of the difference between the upper average air inlet temperature and the set temperature in the current operating mode of the air conditioner is less than or equal to the set second temperature threshold, then return to continue to control the air supply mode of the two or more air guide components of the air outlet to be the third mode in the current operating mode of the air conditioner, and continue to control the frequency of the compressor to be the third frequency set in the current operating mode of the air conditioner.

[0088] Step S450, if it is determined for the second time that the absolute value of the difference between the upper average air inlet temperature and the set temperature in the current operating mode of the air conditioner is greater than the set second temperature threshold, return to re-determine for the second time whether the absolute value of the difference between the lower average air inlet temperature and the set temperature in the current operating mode of the air conditioner is less than or equal to the set first temperature threshold.

[0089] In the scheme of the present invention, by adjusting the air supply mode of more than two air guide components of the air outlet and the third process of the frequency of the compressor, a variety of air supply modes are alternately controlled according to the difference between the upper and lower temperatures of the room and the set temperature, so as to achieve a long-term temperature control effect with low temperature fluctuations. When the ambient temperature is close to the set temperature, the problem of wind discomfort can be improved; different maximum operating frequencies of the compressor are set to correspond to different room temperature differences to achieve energy-saving effects.

[0090] In some embodiments, step S130 adjusts the air supply mode of the two or more air guide components of the air outlet and the frequency of the compressor of the air conditioner based on the set temperature in the current operating mode of the air conditioner and in combination with at least one of the upper average air inlet temperature and the lower average air inlet temperature, and also includes: a fourth process of adjusting the air supply mode of the two or more air guide components of the air outlet and the frequency of the compressor.

[0091] Combine the following Figure 5 The flowchart of an embodiment of the fourth process of adjusting the air supply mode of the two or more air guide components of the air outlet and the frequency of the compressor in the method of the present invention is shown, and the specific process of the fourth process of adjusting the air supply mode of the two or more air guide components of the air outlet and the frequency of the compressor in step S130 is further explained, including: step S510 to step S540.

[0092] Step S510, if it is determined for the first time that the absolute value of the difference between the lower average air inlet temperature and the set temperature in the current operating mode of the air conditioner is less than or equal to the set third temperature threshold, then the air supply mode of the two or more air guide components of the air outlet is controlled to be the third mode in the current operating mode of the air conditioner, and the frequency of the compressor is controlled to 0.

[0093] Step S520: determining for the second time whether the absolute value of the difference between the upper average air inlet temperature and the set temperature in the current operation mode of the air conditioner is less than or equal to the set first temperature threshold.

[0094] Step S530, if it is determined for the second time that the absolute value of the difference between the upper average air inlet temperature and the set temperature in the current operating mode of the air conditioner is less than or equal to the set first temperature threshold, then return to continue controlling the air supply mode of the two or more air guide components of the air outlet to be the third mode in the current operating mode of the air conditioner, and continue to control the frequency of the compressor to 0.

[0095] Step S540, if it is determined for the second time that the absolute value of the difference between the upper average air inlet temperature and the set temperature in the current operating mode of the air conditioner is greater than the set first temperature threshold, then return to continue controlling the air supply mode of the two or more air guide components of the air outlet to be the third mode in the current operating mode of the air conditioner, and continue to control the frequency of the compressor to be the third frequency set in the current operating mode of the air conditioner.

[0096] In the scheme of the present invention, by adjusting the air supply mode of more than two air guide components of the air outlet and the fourth process of the frequency of the compressor, a variety of air supply modes are alternately controlled according to the difference between the upper and lower temperatures of the room and the set temperature, so as to achieve a long-term temperature control effect with low temperature fluctuations, and improve the problem of wind discomfort when the ambient temperature is close to the set temperature; setting different maximum operating frequencies of the compressor to correspond to different room temperature differences can achieve energy-saving effects.

[0097] Fig.11 FIG. 1 is a flow chart of the automatic refrigeration air supply control process of the present invention. Fig.11 As shown in the figure, the automatic air supply control process of refrigeration includes:

[0098] Step a, when the refrigeration is turned on, the upper and lower parts of the inverter cabinet are open to supply air in mode A, and the maximum operating frequency of the compressor is limited to A1; and in the process, it is determined whether the difference between the current temperature of the lower part of the indoor unit's air inlet and the set temperature is less than or equal to the set threshold T1: if so, enter step b; otherwise, the inverter air conditioner cabinet still supplies air in mode A, and the maximum operating frequency of the compressor is limited to A1.

[0099] In the scheme of the present invention, the air conditioner is turned on for refrigeration operation. At this time, the indoor temperature is relatively high. The air conditioner supplies air in mode A. The upper left and right air guide plates, the lower left and right air guide plates, and the upper and lower air guide plates are all turned on. This can increase the indoor air disturbance and quickly cool the indoor temperature. Because air expands when heated and contracts when cooled, the temperature in the lower part of the room is lower than the temperature in the upper part of the room. Therefore, when cooling, it is necessary to first determine whether the temperature in the lower part of the room is close to the set temperature. If so, proceed to the next step. If not, continue to operate at the current level.

[0100] Step b, the air conditioner now supplies air in mode B, and the maximum operating frequency of the compressor is limited to B1; and continue to determine whether the difference between the current upper temperature of the indoor unit air inlet and the set temperature is less than or equal to the set threshold value T2: if so, proceed to step c; otherwise, continue to determine whether the difference between the current lower temperature of the indoor unit air inlet and the set temperature is less than or equal to the set threshold value T1, if so, the air conditioner supplies air in mode B, and the maximum operating frequency of the compressor is limited to B1, otherwise, proceed to step a.

[0101] In the scheme of the present invention, at this time, the lower indoor temperature is close to the set temperature, the air conditioner supplies air in mode B, the upper and lower air guide components are fixed at the upward air guide position, the lower left and right air guide components stop running and are in the minimum air outlet position, and the upper left and right air guide plates operate normally. Because the lower indoor temperature is already close to the set temperature at this time, the upper and lower air guide plates are fixed in the upward air outlet position to prevent the cold air from continuing to blow downward, making the lower indoor temperature lower than the set temperature and continuing to decrease. Similarly, the lower left and right air guide components stop running and are in the minimum air outlet position to prevent the lower indoor temperature from being too low. Because thermal expansion and contraction cause hot air to float up and cold air to sink, the temperature of the upper part of the room is higher than that of the lower part. Therefore, although the temperature of the lower part of the room is close to the set temperature at this time, the temperature of the upper part is still greater than the set temperature. Therefore, the upper left and right air guide plates operate normally, and judge whether the upper temperature of the room is close to the set temperature during operation. If so, proceed to the next step. Otherwise, it depends on whether the indoor cooling capacity is insufficient due to changes in the air supply method and the maximum frequency of the compressor. Therefore, it is necessary to continue to judge whether the lower temperature of the room is still close to the set temperature. If so, continue to operate in this way. Otherwise, it means that the cooling capacity is insufficient, and return to step a.

[0102] Step c, the air conditioner supplies air in mode C at this time, and the maximum operating frequency of the compressor is limited to C1; and continue to determine whether the difference between the current lower temperature of the indoor unit air inlet and the set temperature is less than or equal to the set threshold value T3: if so, proceed to step d; otherwise, continue to determine whether the difference between the current upper temperature of the indoor unit air inlet and the set temperature is less than or equal to the set threshold value T2, if so, the air conditioner supplies air in mode C, and the maximum operating frequency of the compressor is limited to C1, otherwise, continue to determine whether the difference between the current lower temperature of the indoor unit air inlet and the set temperature is less than or equal to the set threshold value T1, if so, proceed to step b, otherwise, proceed to step a; at this time, the upper and lower parts of the room are close to the set temperature, the air conditioner supplies air in mode C, the two left and right air guide components stop running and are in the minimum air outlet position, and the upper and lower air guide components are fixed at the upward air guide position.

[0103] In the scheme of the present invention, only the upper part of the air conditioner blows out weak cold air to maintain the room temperature stable. At this time, it is necessary to judge whether the lower temperature of the room is less than the set temperature within a certain range. If so, proceed to the next step. Due to the change of the air supply mode and the maximum frequency of the compressor, the indoor temperature may not only decrease but also judge whether the upper temperature of the room is less than the set temperature. If so, continue to operate in the current mode, otherwise continue to judge whether the lower temperature of the room is less than the set temperature within a certain range. If so, proceed to b, otherwise proceed to a. Each time the air supply mode is switched, it is necessary to judge whether the current temperature is less than a certain value and greater than another certain value, and then choose to operate in the current mode or enter the next stage or return to other stages according to the judgment.

[0104] Step d, the air conditioner supplies air in mode C at this time, and the compressor stops; and continues to determine whether the difference between the current upper temperature of the indoor unit's air inlet and the set temperature is less than or equal to the set threshold T1: If so, the air conditioner supplies air in mode C at this time, and the compressor stops, otherwise, enters step c; at this time, the lower indoor ambient temperature is lower than the set value within a certain range, and air is supplied in mode C, the compressor stops, and continues to determine whether the upper indoor temperature is lower than the set temperature within a certain range. If so, continue to operate in this manner, otherwise return to c.

[0105] In the scheme of the present invention, the upper and lower open-flow frequency conversion air conditioner can automatically control the movement of the upper and lower air guide components according to the difference between the upper and lower indoor temperatures and the set temperature under the above-mentioned air supply control method. While increasing the temperature rise and temperature drop rates, it can also reduce indoor temperature fluctuations, improve temperature control accuracy, and improve the problem of blowing discomfort.

[0106] Fig.12 The figure is a flow chart of the automatic air supply control process for heating of the present invention. The heating process is similar to the cooling process, except that the temperature is different. Fig.12 As shown in the figure, the automatic air supply control process for heating includes:

[0107] Step e, when the heating is turned on, the upper and lower parts of the inverter cabinet are opened to supply air in mode D, and the maximum operating frequency of the compressor is limited to D1; and in the process, it is determined whether the difference between the set temperature and the upper temperature of the current indoor unit air inlet is less than or equal to the set threshold value T1: if so, enter step f, otherwise the inverter air conditioner cabinet still supplies air in mode A, and the maximum operating frequency of the compressor is limited to A1.

[0108] Step f, the air conditioner now supplies air in mode E, and the maximum operating frequency of the compressor is limited to E1; and continue to determine whether the difference between the set temperature and the current lower temperature of the indoor unit air inlet is less than or equal to the set threshold value T2: if so, proceed to step g, otherwise, continue to determine whether the difference between the set temperature and the current upper temperature of the indoor unit air inlet is less than or equal to the set threshold value T1, if so, the air conditioner supplies air in mode E, and the maximum operating frequency of the compressor is limited to E1, otherwise, proceed to step e.

[0109] Step g, the air conditioner supplies air in mode F at this time, and the maximum operating frequency of the compressor is limited to F1; and continue to determine whether the difference between the set temperature and the upper temperature of the current indoor unit air inlet is less than or equal to the set threshold value T3: if so, enter step h, otherwise, continue to determine whether the difference between the set temperature and the lower temperature of the current indoor unit air inlet is less than or equal to the set threshold value T2, if so, the air conditioner supplies air in mode F, and the maximum operating frequency of the compressor is limited to F1, otherwise, continue to determine whether the difference between the set temperature and the upper temperature of the current indoor unit air inlet is less than or equal to the set threshold value T1, if so, enter step f, otherwise, enter step e.

[0110] Step h, the air conditioner supplies air in mode F at this time, and the compressor stops; and continues to determine whether the difference between the set temperature and the current temperature at the lower part of the indoor unit's air inlet is less than or equal to the set threshold T1: if so, the air conditioner supplies air in mode D at this time, and the compressor stops, otherwise, enter step g.

[0111] The scheme of the present invention proposes an automatic air supply control scheme for an upper and lower split air guide variable frequency air conditioner, which solves the problems of condensation and blowing discomfort caused by only adjusting the wind speed in related schemes, and improves the accuracy of temperature control while ensuring the air conditioning effect, thereby improving comfort. In the scheme of the present invention, multiple intervals are divided according to the difference between the upper and lower ambient temperatures and the set temperature of the room, and each temperature interval corresponds to a certain action mode of the upper and lower air guide plates. By limiting the maximum operating frequency of the compressor in different intervals, the greater the temperature difference, the higher the compressor operating frequency, and the smaller the temperature difference, the lower the compressor operating frequency, thereby ensuring the energy efficiency of the air conditioner while reducing the risk of condensation.

[0112] In some embodiments, the upper left and right wind guide assembly includes: upper left and right wind guide plates, which can be rotated to change their angles or moved to change their positions and can stay at the rotated angles or moved positions, and the running speed and staying time of the upper left and right wind guide plates at the staying angles or staying positions can be adjusted; the lower left and right wind guide assembly includes: lower left and right wind guide plates, which can be rotated to change their angles or moved to change their positions and can stay at the rotated angles or moved positions, and the running speed and staying time of the lower left and right wind guide plates at the staying angles or staying positions can be adjusted; the upper and lower wind guide assemblies include: upper and lower wind guide plates, which can be rotated to change their angles or moved to change their positions and can stay at the rotated angles or moved positions, and the running speed and staying time of the upper and lower wind guide plates at the staying angles or staying positions can be adjusted. Among them, the air guide component (i.e., the air guide assembly) includes a plurality of air guide plates, each of which has its own axis. The air guide plates can rotate along the axis, which is called the swing of air guide blades in the control of the air conditioner. The solution of the present invention is mainly aimed at the movement form of the swing of air guide blades; in addition, there is a kind of air guide plate of the entire moving part of the air guide component is fixed together and moves left and right along the same axis. This situation can also be applied to the solution of the present invention.

[0113] In the scheme of the present invention, the left and right air outlet ranges corresponding to the upper and lower temperature detection devices are defined as the left and right air guide plate sweeping ranges divided into five parts, corresponding to the temperature detection devices one by one from left to right, the upper left and right air guide plates correspond to the upper temperature detection devices, and the lower left and right air guide plates correspond to the lower temperature detection devices. The air outlet angles corresponding to the three middle temperature detection devices in the upper and lower parts are the angles corresponding to the center position of the air outlet range corresponding to the temperature detection devices, and the air outlet angles corresponding to the leftmost and rightmost temperature detection devices are the angles corresponding to the leftmost and rightmost of the corresponding air guide plate movement range. The air outlet range of the middle vertical temperature detection device is the upper and lower air guide plate sweeping range divided into five parts, corresponding to the temperature detection devices one by one from top to bottom, the air outlet angles corresponding to the three middle temperature detection devices in the vertical direction are the angles corresponding to the center position of the air outlet range corresponding to the temperature detection devices, and the air outlet angles corresponding to the uppermost and rightmost temperature detection devices are the angles corresponding to the uppermost and lowermost of the corresponding upper and lower air guide plate movement range. This section describes the definition of the air outlet range and air outlet angles.

[0114] In the scheme of the present invention, the temperature detection device is divided into three parts, namely, five temperature detection devices evenly distributed along the horizontal circumference of the air inlet at the upper part, five temperature detection devices evenly distributed along the horizontal circumference of the air inlet at the lower part, and five temperature detection devices evenly distributed along the vertical direction in the middle of the air inlet. Because the top and bottom two temperature detection devices of the vertically distributed temperature detection device are shared with the temperature detection devices in the middle of the upper horizontal distribution and the lower horizontal distribution, there are a total of thirteen temperature detection devices. Among them, the five temperature detection devices evenly distributed along the horizontal circumference of the air inlet at the upper part correspond to the upper left and right air guide plates; the five temperature detection devices evenly distributed along the horizontal circumference of the air inlet at the lower part correspond to the lower left and right air guide plates, and the five temperature detection devices evenly distributed along the vertical direction in the middle of the air inlet correspond to the upper and lower air guide plates.

[0115] Among them, in step S140, when the air conditioner is operated according to the air supply mode of the two or more air guide components of the air outlet, combined with the m upper air inlet temperatures and the upper average air inlet temperature, the n lower air inlet temperatures and the lower average air inlet temperature, and the p middle air inlet temperatures and at least one of the middle average air inlet temperature, at least one of the operating speeds and the residence times of the two or more air guide components of the air outlet at the corresponding positions is adjusted, including: when the air supply mode of the two or more air guide components of the air outlet is the first mode, the process of adjusting at least one of the operating speeds and the residence times of the two or more air guide components of the air outlet at the corresponding positions under the first mode.

[0116] Combine the following Figure 6The method of the present invention is shown as a flowchart of an embodiment of the process of adjusting at least one of the operating speeds and residence times of two or more air guide components of the air outlet at corresponding positions in a first manner, further illustrating the specific process of adjusting at least one of the operating speeds and residence times of two or more air guide components of the air outlet at corresponding positions in a first manner in step S140, including: steps S610 to S660.

[0117] Step S610, when the air supply mode of more than two air guide components of the air outlet is the first mode, determine the absolute value of the difference between each upper air inlet temperature among the m upper air inlet temperatures and the upper average air inlet temperature, and record it as the absolute value of the temperature difference at the first air inlet angle; determine the absolute value of the difference between each lower air inlet temperature among the n lower air inlet temperatures and the lower average air inlet temperature, and record it as the absolute value of the temperature difference at the second air inlet angle; and determine the absolute value of the difference between each middle air inlet temperature among the p middle air inlet temperatures and the middle average air inlet temperature, and record it as the absolute value of the temperature difference at the third air inlet angle.

[0118] Step S620, for each of the absolute values ​​of the temperature difference of the first air inlet angle, the absolute value of the temperature difference of the second air inlet angle, and the absolute value of the temperature difference of the third air inlet angle, determine the temperature interval to which the absolute value of the temperature difference of each air inlet angle belongs within the set temperature range; wherein the temperature interval includes: a first interval, a second interval, a third interval, and a fourth interval in which the temperature values ​​increase in sequence; the upper left and right air guide plates, the lower left and right air guide plates, and the upper and lower air guide plates corresponding to each of the air inlet angles are placed; The wind guide plate corresponding to the absolute value of the temperature difference is recorded as the corresponding wind guide plate; and the temperature detection devices among the m temperature detection devices, the n temperature detection devices, and the p temperature detection devices corresponding to the absolute value of the temperature difference at each air inlet angle are recorded as corresponding temperature detection devices; wherein, taking the absolute value of the temperature difference at the first air inlet angle as an example, the first interval is the interval of α1≤t1, the second interval is the interval of t1<α1≤t2, the third interval is the interval of t3≤α1<t4, and the fourth interval is the interval of t4≤α1.

[0119] Step S630, if the absolute value of the temperature difference of each air inlet angle is in the first interval, the corresponding air guide plate is controlled to increase its operating speed by a set first coefficient when it moves to the air outlet range or air outlet angle corresponding to the corresponding temperature detection device; wherein the set first coefficient is 1 times.

[0120] Step S640, if the absolute value of the temperature difference of each air inlet angle is in the second interval, the corresponding air guide plate is controlled to increase its operating speed by a set second coefficient when it moves to the air outlet range corresponding to the corresponding temperature detection device; wherein the set second coefficient is smaller than the set first coefficient, and the set first coefficient is such as 1 times.

[0121] Step S650, if the absolute value of the temperature difference of each air inlet angle is in the third interval, control the corresponding air guide plate to stay for a set first stay time when it moves to the air outlet range corresponding to the air outlet range of the corresponding temperature detection device; wherein the set first stay time is, for example, 0.5s.

[0122] Step S660, if the absolute value of the temperature difference of each air inlet angle is in the fourth interval, the corresponding air guide plate is controlled to stay for a set second stay time when it moves to the air outlet range corresponding to the air outlet range corresponding to the corresponding temperature detection device; wherein the set second stay time is greater than the set first stay time, and the set second stay time is such as 1s.

[0123] Fig.13 Schematic diagram of the air supply process of mode A of the present invention. Fig.13 As shown, air supply in mode A: the upper and lower left and right air guide components operate alternately, the upper and lower air guide components operate independently, and the difference α1 between the temperature detected by the upper temperature detection device and the upper temperature of the incoming air, the difference β1 between the temperature detected by the lower temperature detection device and the lower temperature of the incoming air, and the difference γ1 between the temperature detected by the middle vertical direction temperature detection device and the middle temperature of the incoming air are continuously determined during the process. In mode A air supply, the upper and lower air guide components are not affected by the left and right air guide components, and the upper and lower air guide blades swing up and down when the upper and lower air guide components operate independently, and the air guide plates swing left and right when the left and right air guide components operate.

[0124] If α1≤t1, when the upper left and right air guide plates move to the air outlet range corresponding to the corresponding temperature detection device, the operating speed of the upper left and right air guide plates increases by 1 times; if t1<α1≤t2, when the upper left and right air guide plates move to the air outlet range corresponding to the corresponding temperature detection device, the operating speed increases by 0.5 times; if t3≤α1<t4, when the upper left and right air guide plates move to the air outlet angle corresponding to the corresponding temperature detection device, they stay for 0.5 seconds; if t4≤α1, when the upper left and right air guide plates move to the air outlet angle corresponding to the corresponding temperature detection device, they stay for 1 second. Among them, when α1≤t1 and the upper left and right air guide plates move to the air outlet range corresponding to the corresponding temperature detection device, the inlet air temperature at this position is lower than the upper average temperature, so the air guide plates should move quickly when they move to the air outlet range corresponding to the temperature detection device to reduce the time the air guide plates are in this range, thereby reducing the cooling output and reducing the indoor temperature difference.

[0125] If β1≤t1, when the lower left and right air guide plates move to the air outlet range corresponding to the corresponding temperature detection device, the operating speed is increased by 1 times; if t1<β1≤t2, when the lower left and right air guide plates move to the air outlet range corresponding to the corresponding temperature detection device, the operating speed is increased by 0.5 times; if t3≤β1<t4, when the lower left and right air guide plates move to the air outlet angle corresponding to the corresponding temperature detection device, they stay for 0.5 seconds; if t4≤β1, when the lower left and right air guide plates move to the air outlet angle corresponding to the corresponding temperature detection device, they stay for 1 second.

[0126] If γ1≤t1, when the upper and lower air guide plates move to the air outlet range corresponding to the corresponding temperature detection device, the operating speed is increased by 1 times; if t1<γ1≤t2, when the upper and lower air guide plates move to the air outlet range corresponding to the corresponding temperature detection device, the operating speed is increased by 0.5 times; if t3≤γ1<t4, when the upper and lower air guide plates move to the air outlet angle corresponding to the corresponding temperature detection device, they stay for 0.5 seconds; if t4≤γ1, when the upper and lower air guide plates move to the air outlet angle corresponding to the corresponding temperature detection device, they stay for 1 second.

[0127] In the solution of the present invention, this operating mode (i.e., mode A air supply) can increase the room air disturbance, improve the room temperature uniformity, increase the temperature drop rate, and quickly cool the room to approach the set temperature.

If t4≤γ1, when the upper and lower air guide plates move to the air outlet range corresponding to the corresponding temperature detection device, the operating speed is increased by 1 times.

[0129] In the solution of the present invention, this operating mode (D mode air supply) can increase the room air disturbance, improve the room temperature uniformity, increase the temperature rise rate, and make the room temperature rise quickly close to the set temperature.

[0130] In some embodiments, in step S140, when the air conditioner is operated according to the air supply mode of the two or more air guide components of the air outlet, at least one of the operating speeds and the residence times of the two or more air guide components of the air outlet at corresponding positions are adjusted in combination with the m upper air inlet temperatures and the upper average air inlet temperature, the n lower air inlet temperatures and the lower average air inlet temperature, and the p middle air inlet temperatures and at least one of the middle average air inlet temperature. The process also includes: when the air supply mode of the two or more air guide components of the air outlet is the second mode, at least one of the operating speeds and the residence times of the two or more air guide components of the air outlet at corresponding positions are adjusted in the second mode.

[0131] Combine the following Figure 7 The method of the present invention is shown as a flowchart of an embodiment of the process of adjusting at least one of the operating speeds and residence times of two or more air guide components at corresponding positions of the air outlet in a second mode, further illustrating the specific process of adjusting at least one of the operating speeds and residence times of two or more air guide components at corresponding positions of the air outlet in a second mode in step S140, including: steps S710 to S760.

[0132] Step S710, when the air supply mode of more than two air guide components of the air outlet is the second mode, determine the absolute value of the difference between each upper air inlet temperature of the m upper air inlet temperatures and the upper average air inlet temperature, and record it as the absolute value of the temperature difference at the first air inlet angle.

[0133] Step S720, determine the temperature interval to which the absolute value of the temperature difference of the first air inlet angle belongs within the set temperature range; wherein the temperature interval includes: a first interval, a second interval, a third interval and a fourth interval in which the temperature values ​​increase successively; and, the temperature detection device corresponding to the absolute value of the temperature difference of the first air inlet angle among the m temperature detection devices is recorded as a corresponding temperature detection device; wherein, taking the absolute value of the temperature difference of the first air inlet angle as an example, the first interval is an interval of α1≤t1, the second interval is an interval of t1<α1≤t2, the third interval is an interval of t3≤α1<t4, and the fourth interval is an interval of t4≤α1.

[0134] Step S730, if the absolute value of the temperature difference of the first air inlet angle is in the first interval, the upper left and right air guide plates are controlled to increase their operating speed by a set first coefficient when they move to the air outlet range or air outlet angle corresponding to the corresponding temperature detection device; wherein the set first coefficient is 1 times.

[0135] Step S740, if the absolute value of the temperature difference of the first air inlet angle is in the second interval, the upper left and right air guide plates are controlled to increase their operating speed by a set second coefficient when they move to the air outlet range corresponding to the air outlet range corresponding to the corresponding temperature detection device; wherein the set second coefficient is smaller than the set first coefficient, and the set first coefficient is such as 1 times.

[0136] Step S750, if the absolute value of the temperature difference of the first air inlet angle is in the third interval, the upper left and right air guide plates are controlled to stay for a set first stay time when they move to the air outlet range corresponding to the air outlet range corresponding to the corresponding temperature detection device; wherein the set first stay time is, for example, 0.5s.

[0137] Step S760, if the absolute value of the temperature difference of the first air inlet angle is in the fourth interval, the upper left and right air guide plates are controlled to stay for a set second stay time when they move to the air outlet range corresponding to the air outlet range corresponding to the corresponding temperature detection device; wherein the set second stay time is greater than the set first stay time, and the set second stay time is such as 1s.

[0138] Fig.14 FIG. 1 is a flow chart of the air supply process of mode B of the present invention. Fig.14 As shown, air supply is carried out in mode B: the upper left and right air guide components are running, the lower left and right air guide components stop running and are in the minimum air outlet position, the upper and lower air guide components are fixed at the upward air guide position, and the difference α1 between the temperature detected by the upper temperature detection device and the upper temperature of the inlet air is continuously judged during the process.

[0139] If α1≤t1, when the upper left and right air guide plates move to the air outlet range corresponding to the corresponding temperature detection device, the operating speed is increased by 1 times; if t1<α1≤t2, when the upper left and right air guide plates move to the air outlet range corresponding to the corresponding temperature detection device, the operating speed is increased by 0.5 times; if t3≤α1<t4, when the upper left and right air guide plates move to the air outlet angle corresponding to the corresponding temperature detection device, they stay for 0.5 seconds; if t4≤α1, when the upper left and right air guide plates move to the air outlet angle corresponding to the corresponding temperature detection device, they stay for 1 second.

[0140] In the solution of the present invention, this operating mode (mode B air supply) can effectively reduce the wind feeling at the bottom of the air conditioner, improve the uniformity of room temperature, and prevent excessive vertical temperature differences in the room.

[0141] Air supply in mode C: Both left and right air guide components stop running and are in the minimum air outlet position. The upper and lower air guide components are fixed in the upward air guide position. At this time, the temperature in the upper part of the room is close to the set temperature, and the temperature in the lower part of the room is slightly lower than the set temperature. The overall temperature of the room is closest to the set temperature. The air conditioner only blows out weak cold air from the upper part of the air outlet to keep the room temperature stable.

[0142] According to experiments, the difference T1 can be 0℃~2℃, preferably 1℃; the difference T2 can be -1℃~1℃, preferably 0℃; the difference T3 can be -3℃~-1℃, preferably -2℃. The t1 can be -1℃~0℃, preferably -0.5℃, the t2 can be -0.5℃~0℃, preferably -0.2℃, the t3 can be 0℃~0.5℃, preferably 0.2℃, and the t4 can be 0℃~1℃, preferably 0.5℃.

[0143] In the scheme of the present invention, this embodiment sets the maximum operating frequency of the compressor A1>B1>C1, because the load of the air conditioner in the refrigerated room will gradually decrease, and the maximum operating frequency of the compressor can be reduced, thereby saving energy; in the cooling mode, the air conditioner is in the B mode air supply (the lower left and right air guide components are fixed at the minimum air outlet) and C mode air supply (the upper and lower left and right sweeping components are fixed at the minimum air outlet), the overall air volume will be reduced, if the frequency is not changed, the air outlet temperature will be reduced, and there will be a risk of condensation when the air outlet temperature is lower than the indoor dew point temperature. Therefore, in the cooling mode, when the air conditioner is in the B mode air supply and the C mode air supply, it is also necessary to gradually reduce the maximum operating frequency of the compressor, increase the air outlet temperature, and avoid condensation. Among them, the maximum operating frequency of compressors with different displacements is different, and the limiting frequency of each stage is also different. The references for conventional household compressors are as follows: A1: 60Hz~120Hz, B1: 40Hz~80Hz~, C1: 15Hz~50Hz, and the same compressor should ensure A1>B1>C1.

[0144] Fig.16 Schematic diagram of the E-mode air supply process of the present invention. Fig.16 As shown, the E-mode air supply: the lower left and right air guide components are running, the upper left and right air guide components stop running and are at the minimum air outlet position, the upper and lower air guide components are fixed at the downward air guide position, and the difference β2 between the temperature detected by the lower temperature detection device and the lower temperature of the air inlet is continuously judged during the process. If β2≤t1, the lower left and right air guide plates move to the air outlet angle corresponding to the corresponding temperature detection device and stay for 1 second. If t1<β2≤t2, the lower left and right air guide plates move to the air outlet angle corresponding to the corresponding temperature detection device and stay for 0.5 seconds. If t3≤β2<t4, the lower left and right air guide plates move to the air outlet range corresponding to the corresponding temperature detection device, and the operating speed is increased by 0.5 times. If t4≤β2, the lower left and right air guide plates move to the air outlet range corresponding to the corresponding temperature detection device and the operating speed is increased by 1 times.

[0145] In the solution of the present invention, this operating mode (E-mode air supply) can effectively reduce the wind feeling on the upper part of the air conditioner, improve the uniformity of room temperature, and prevent excessive vertical temperature difference in the room.

[0146] F mode air supply: Both left and right air guide components stop running and are in the minimum air outlet position, and the upper and lower air guide components are fixed in the downward air guide position. At this time, the temperature in the lower part of the room is close to the set temperature, and the temperature in the upper part of the room is slightly higher than the set temperature. The overall temperature of the room is closest to the set temperature. The air conditioner only blows out weak hot air from the lower part of the air outlet to keep the room temperature stable.

[0147] In the scheme of the present invention, this embodiment sets the maximum operating frequency of the compressor D1>E1>F1, mainly because the load in the air-conditioned heating room will gradually decrease, and the maximum operating frequency of the compressor can be reduced, thereby saving energy. The value range of the difference T1, T2 and T3 of the heating temperature is the same as that of the cooling, and the value range of the temperature t1, t2, t3 and t4 is the same as that of the cooling. The air outlet range corresponding to the temperature detection device and the air outlet angle corresponding to the temperature detection device are consistent with those of the cooling. Among them, the maximum operating frequency of compressors with different displacements is different, and the limiting frequency of each stage is also different. The references for conventional household compressors are as follows: D1: 60Hz~120Hz, E1: 40Hz~80Hz, F1: 15Hz~50Hz. The same compressor should ensure D1>E1>F1.

The air supply mode of the air conditioner is adjusted according to the comparison between the ambient temperature of the upper and lower parts of the room and the set temperature, and the difference between the inlet temperature at different air inlet angles and the average temperature. This can achieve rapid temperature rise and drop, maintain high-precision temperature control and reduce the discomfort caused by the wind, thereby greatly improving the comfort of the air conditioner.

[0149] In the scheme of the present invention, the temperature control accuracy is high: according to the difference between the upper and lower temperatures of the room and the set temperature, a variety of air supply modes are used for alternating control to achieve a long-term temperature control effect with low temperature fluctuations. In the scheme of the present invention, energy saving: different maximum operating frequencies of the compressor are set to correspond to different room temperature differences to achieve energy saving effects, and reduce the risk of condensation in the cooling mode. In the scheme of the present invention, wind comfort: according to the difference between the ambient temperature and the set temperature, the air supply mode is adjusted, and when the ambient temperature is close to the set temperature, the problem of wind discomfort can be improved.

[0151] According to an embodiment of the present invention, a control device for an air conditioner corresponding to the control method for an air conditioner is also provided. Figure 8 The structure diagram of one embodiment of the device of the present invention is shown. The control device of the air conditioner is applied to the air supply control of the air conditioner with upper and lower air guides, the air conditioner has an air inlet and an air outlet, the air outlet has two or more air guide components, the two or more air guide components of the air outlet can operate in different air supply modes, and the compressor of the air conditioner can operate at different frequencies; m temperature detection devices are correspondingly arranged at the m air inlet angles at the upper part of the air inlet, n temperature detection devices are correspondingly arranged at the n air inlet angles at the lower part of the air inlet, and p temperature detection devices are correspondingly arranged at the p air inlet angles at the middle part of the air inlet, m, n, and p are all positive integers, preferably m=5, n=5, and p=3; in the scheme of the present invention, Figure 8As shown, the air conditioner control device includes: an acquisition unit 102 and a control unit 104.

[0152] The acquisition unit 102 is configured to acquire the temperature detected by each of the m temperature detection devices to obtain m upper air inlet temperatures; acquire the temperature detected by each of the n temperature detection devices to obtain n lower air inlet temperatures; acquire the temperature detected by each of the p temperature detection devices to obtain p middle air inlet temperatures; and acquire the set temperature in the current operation mode of the air conditioner; wherein the current operation mode of the air conditioner includes: the cooling mode of the air conditioner or the heating mode of the air conditioner. The specific functions and processing of the acquisition unit 102 refer to step S110.

[0153] The control unit 104 is configured to determine an average value of the m upper air inlet temperatures, recorded as the upper average air inlet temperature, such as Fig.12 The current temperature of the upper part of the indoor unit air inlet is shown.

The specific functions and further processing of the control unit 104 refer to step S140.

[0156] The scheme of the present invention proposes an automatic air supply control scheme for an air conditioner with upper and lower separate air guides. The automatic air supply scheme is adopted to adjust the air supply mode of the air conditioner according to the comparison between the ambient temperature and the set temperature of the upper and lower parts of the room, and the difference between the air inlet temperature and the average temperature at different air inlet angles. Not only can rapid temperature rise and drop be achieved, but also high-precision temperature control can be maintained and the discomfort caused by wind sensation can be reduced, thereby greatly improving the comfort of the air conditioner.

[0157] In some embodiments, the two or more air guide components of the air outlet include: an upper left and right air guide component located at the upper part of the air outlet, a lower left and right air guide component located at the lower part of the air outlet, and an upper and lower air guide component located between the upper and lower parts of the air outlet; the air supply mode of the two or more air guide components of the air outlet includes: at least one of: a first mode under the current operating mode of the air conditioner, a second mode under the current operating mode of the air conditioner, and a third mode under the current operating mode of the air conditioner.

[0158] Among them, the first mode in the current operation mode of the air conditioner is: the upper left and right air guide components and the lower left and right air guide components operate alternately, and the upper and lower air guide components operate independently; for example: mode A in cooling mode, or mode D in heating mode.

[0159] The second mode under the current operation mode of the air conditioner is: the upper left and right air guide components are running, the lower left and right air guide components are stopped and are in the minimum air outlet position, and the upper and lower air guide components are fixed to guide air upward; for example: mode B in cooling mode, or mode E in heating mode.

[0160] The third mode under the current operating mode of the air conditioner is: the upper left and right air guide components and the lower left and right air guide components both stop running and are in the minimum air outlet position, and the upper and lower air guide components are fixed to guide air upward; for example: mode C under cooling mode, or mode F under heating mode.

[0161] Fig. 9 It is a structural schematic diagram of an air guide structure with upper and lower parts for guiding air. Fig. 9The invention comprises two upper and lower left and right wind guide components (such as upper left and right wind sweeping components 3 and lower left and right wind sweeping components 4), a driving component (such as driving component 2) and an air outlet frame (such as air outlet frame 1). The left and right wind guide components and the driving component are connected to the air outlet frame. The driving component can simultaneously control the upper and lower left and right wind guide components, so that the upper and lower left and right wind guide components can run alternately or independently. Fig. 9 In the example shown, the left and right air guide blades are divided into two upper and lower parts.

[0162] exist Fig.11 In the control scheme under the cooling operation mode shown, there are three air-conditioning air guide components, namely the upper left and right air guide components, the lower left and right air guide components and the upper and lower air guide components. The three air supply methods are described as follows: A method air supply, B method air supply, and C method air supply.

[0163] exist Fig.12 In the control scheme under the heating operation mode shown, three air supply modes are described as follows: D mode air supply, E mode air supply, and F mode air supply.

[0164] In the scheme of the present invention, asynchronous air guiding: the upper and lower left and right air guiding components move asynchronously and staggeredly to increase indoor air disturbance and promote temperature exchange. Single-sided air guiding: only one of the upper and lower left and right air guiding components is in operation, and the other left and right air guiding components are closed or fixed in a certain position, so that only the upper or lower part of the air conditioner performs left and right air guiding operation. The automatic air supply control scheme of the upper and lower separated air guiding air conditioner is adopted. According to the comparison between the ambient temperature of the upper and lower parts of the room and the set temperature, the air supply mode of the air conditioner is adjusted, which can achieve rapid temperature rise and temperature drop, perform high-precision temperature control and reduce the discomfort caused by the wind, improve the comfort of the air conditioner, and solve the problems of complex adjustment of the air supply mode and wind discomfort of the upper and lower separated air guiding air conditioner.

[0165] In some embodiments, the m temperature detection devices are uniformly arranged circumferentially along the air inlet direction of the upper part of the air inlet in the air inlet area of ​​the upper part of the air inlet; the n temperature detection devices are uniformly arranged circumferentially along the air inlet direction of the lower part of the air inlet in the air inlet area of ​​the lower part of the air inlet; the p temperature detection devices are vertically distributed in the air inlet area of ​​the middle part of the air inlet along the middle part of the air inlet.

[0166] Fig.10 The following is a schematic diagram of the distribution of the air conditioner temperature detectors of the present invention, wherein (a) is a schematic diagram of the temperature detection device distributed along the horizontal circumference of the air inlet, and (b) is a schematic diagram of the temperature detection device distributed along the middle of the air inlet vertically. Fig.10As shown, the air conditioner has an indoor heat exchanger 6, an indoor fan 7, upper and lower air guide components 8, left and right air guide components 9, and an indoor air inlet area 10. Five temperature detectors (such as temperature sensor 5) are evenly distributed along the air inlet area at the upper and lower parts of the air conditioner, and five temperature detectors are also evenly distributed along the vertical direction in the middle of the air inlet (the top and bottom two temperature detectors are shared with the upper and lower temperature detectors of the air conditioner). There are thirteen temperature detectors in total. The average temperature detected by the five upper temperature detection devices represents the upper temperature of the indoor air inlet, the average temperature detected by the five lower temperature detection devices represents the lower temperature of the indoor air inlet, and the average temperature detected by the five temperature detection devices in the vertical direction in the middle of the air inlet represents the middle temperature of the air inlet. Fig.10 In the example shown, the operation of different air guide plates can be adjusted according to different temperature differences by using multiple air inlet temperature detection devices.

[0167] In the scheme of the present invention, a total of thirteen temperature detection devices are arranged at the air inlet of the air conditioner, namely, five temperature detection devices distributed along the horizontal circumference of the upper part of the air inlet, five temperature detection devices distributed along the horizontal circumference of the lower part of the air inlet, and five temperature detection devices distributed along the vertical direction of the air inlet in the middle of the air inlet, two of which are repeated, so there are a total of thirteen temperature detection devices. The three groups of temperature detection devices are evenly placed. In the scheme of the present invention, the air inlet angle is only a rough statement. The essence is that different temperature detection devices use different air guide plates with different wind sweeping ranges and wind sweeping angles. Among them, the five temperature detection devices evenly distributed along the horizontal circumference of the upper part of the air inlet correspond to the upper left and right air guide plates; the five temperature detection devices evenly distributed along the horizontal circumference of the lower part of the air inlet correspond to the lower left and right air guide plates, and the five temperature detection devices evenly distributed along the vertical direction in the middle of the air inlet correspond to the upper and lower air guide plates.

[0168] In the scheme of the present invention, there are three average temperatures, namely, the upper temperature of the air inlet representing the upper temperature of the room, the lower temperature of the air inlet representing the lower temperature of the room, and the middle temperature of the air inlet representing the air inlet temperature. Set temperature: the target temperature set by the air conditioner. Upper air inlet temperature: the indoor ambient temperature above the air inlet of the air conditioner indoor unit is represented by the average value of the five temperature detection devices located at the upper part of the air inlet. Lower air inlet temperature: the indoor ambient temperature below the air inlet of the air conditioner indoor unit is represented by the average value of the five temperature detection devices located at the lower part of the air inlet. Middle air inlet temperature: represented by the average value of the five temperature detection devices located in the middle of the air inlet and distributed in the vertical direction.

[0169] The air conditioner corresponding to the scheme of the present invention is a variable frequency air conditioner with upper and lower parts for air guiding, and there are two upper and lower left and right air guiding components and an upper and lower air guiding component connecting the upper and lower parts of the air outlet at the air outlet, and there are more than ten temperature detection devices in the air conditioner, which are respectively located at the upper part of the air inlet and the lower part of the air inlet, and are used to detect the upper ambient temperature of the room and the lower ambient temperature of the room, wherein the average temperature detected by the five upper temperature detection devices represents the upper temperature of the air inlet of the indoor unit, and the average temperature detected by the five lower temperature detection devices represents the lower temperature of the air inlet of the indoor unit. The air conditioner can be a cabinet unit or other hanging units, window units, etc. with upper and lower air guiding components. Among them, the five temperature detection devices are evenly distributed along the horizontal circumference of the air inlet, and the five temperature detection devices are because on the one hand, they can accurately identify the temperature at different angles on the left and right sides of the room, and on the other hand, they can also save costs. Because if there are too few temperature detection devices, such as two or three, the temperature difference at multiple angles cannot be represented, and it is impossible to achieve directional temperature control at multiple angles, and if there are too many, it will be too wasteful, which will increase the cost on the one hand, and on the other hand, the indoor temperature difference is relatively rough, and there will not be obvious temperature differences every few degrees, so too many temperature detection devices are not needed. Therefore, setting five temperature detection devices is a more appropriate number of temperature detection devices.

[0170] In some embodiments, the control unit 104 adjusts the air supply mode of the two or more air guide components of the air outlet and the frequency of the compressor of the air conditioner based on the set temperature in the current operation mode of the air conditioner in combination with at least one of the upper average air inlet temperature and the lower average air inlet temperature, including: a first process of adjusting the air supply mode of the two or more air guide components of the air outlet and the frequency of the compressor, specifically as follows:

[0171] The control unit 104 is further configured to control the air supply mode of the two or more air guide components of the air outlet to be the first mode in the current operation mode of the air conditioner, and control the frequency of the compressor to be the first frequency set in the current operation mode of the air conditioner. The specific functions and further processing of the control unit 104 refer to step S210.

[0172] The control unit 104 is further configured to determine for the first time whether the absolute value of the difference between the lower average air inlet temperature and the set temperature in the current operation mode of the air conditioner is less than or equal to a set first temperature threshold; wherein the set first frequency is, for example, the frequency A1 in the cooling mode or the frequency D1 in the heating mode, and the set first temperature threshold is the set threshold T1. The specific functions and further processing of the control unit 104 refer to step S220.

[0194] In the scheme of the present invention, by adjusting the air supply mode of more than two air guide components of the air outlet and the fourth process of the frequency of the compressor, a variety of air supply modes are alternately controlled according to the difference between the upper and lower temperatures of the room and the set temperature, so as to achieve a long-term temperature control effect with low temperature fluctuations, and improve the problem of wind discomfort when the ambient temperature is close to the set temperature; setting different maximum operating frequencies of the compressor to correspond to different room temperature differences can achieve energy-saving effects.

[0195] Fig.11 FIG. 1 is a flow chart of the automatic refrigeration air supply control process of the present invention. Fig.11 As shown in the figure, the automatic air supply control process of refrigeration includes:

[0196] Step a, when the refrigeration is turned on, the upper and lower parts of the inverter cabinet are open to supply air in mode A, and the maximum operating frequency of the compressor is limited to A1; and in the process, it is determined whether the difference between the current temperature of the lower part of the indoor unit's air inlet and the set temperature is less than or equal to the set threshold T1: if so, enter step b; otherwise, the inverter air conditioner cabinet still supplies air in mode A, and the maximum operating frequency of the compressor is limited to A1.

[0197] In the scheme of the present invention, the air conditioner is turned on for refrigeration operation. At this time, the indoor temperature is relatively high. The air conditioner supplies air in mode A. The upper left and right air guide plates, the lower left and right air guide plates, and the upper and lower air guide plates are all turned on. This can increase the indoor air disturbance and quickly cool the indoor temperature. Because air expands when heated and contracts when cooled, the temperature in the lower part of the room is lower than the temperature in the upper part of the room. Therefore, when cooling, it is necessary to first determine whether the temperature in the lower part of the room is close to the set temperature. If so, proceed to the next step. If not, continue to operate at the current level.

[0198] Step b, the air conditioner now supplies air in mode B, and the maximum operating frequency of the compressor is limited to B1; and continue to determine whether the difference between the current upper temperature of the indoor unit air inlet and the set temperature is less than or equal to the set threshold value T2: if so, proceed to step c; otherwise, continue to determine whether the difference between the current lower temperature of the indoor unit air inlet and the set temperature is less than or equal to the set threshold value T1, if so, the air conditioner supplies air in mode B, and the maximum operating frequency of the compressor is limited to B1, otherwise, proceed to step a.

[0199] In the scheme of the present invention, at this time, the lower indoor temperature is close to the set temperature, the air conditioner supplies air in mode B, the upper and lower air guide components are fixed at the upward air guide position, the lower left and right air guide components stop running and are in the minimum air outlet position, and the upper left and right air guide plates operate normally. Because the lower indoor temperature is already close to the set temperature at this time, the upper and lower air guide plates are fixed in the upward air outlet position to prevent the cold air from continuing to blow downward, making the lower indoor temperature lower than the set temperature and continuing to decrease. Similarly, the lower left and right air guide components stop running and are in the minimum air outlet position to prevent the lower indoor temperature from being too low. Because thermal expansion and contraction cause hot air to float up and cold air to sink, the temperature of the upper part of the room is higher than that of the lower part. Therefore, although the temperature of the lower part of the room is close to the set temperature at this time, the temperature of the upper part is still greater than the set temperature. Therefore, the upper left and right air guide plates operate normally, and judge whether the upper temperature of the room is close to the set temperature during operation. If so, proceed to the next step. Otherwise, it depends on whether the indoor cooling capacity is insufficient due to changes in the air supply method and the maximum frequency of the compressor. Therefore, it is necessary to continue to judge whether the lower temperature of the room is still close to the set temperature. If so, continue to operate in this way. Otherwise, it means that the cooling capacity is insufficient, and return to step a.

[0200] Step c, the air conditioner supplies air in mode C at this time, and the maximum operating frequency of the compressor is limited to C1; and continue to determine whether the difference between the current lower temperature of the indoor unit air inlet and the set temperature is less than or equal to the set threshold value T3: if so, proceed to step d; otherwise, continue to determine whether the difference between the current upper temperature of the indoor unit air inlet and the set temperature is less than or equal to the set threshold value T2, if so, the air conditioner supplies air in mode C, and the maximum operating frequency of the compressor is limited to C1, otherwise, continue to determine whether the difference between the current lower temperature of the indoor unit air inlet and the set temperature is less than or equal to the set threshold value T1, if so, proceed to step b, otherwise, proceed to step a; at this time, the upper and lower parts of the room are close to the set temperature, the air conditioner supplies air in mode C, the two left and right air guide components stop running and are in the minimum air outlet position, and the upper and lower air guide components are fixed at the upward air guide position.

[0201] In the scheme of the present invention, only the upper part of the air conditioner blows out weak cold air to maintain the room temperature stable. At this time, it is necessary to judge whether the lower temperature of the room is less than the set temperature within a certain range. If so, proceed to the next step. Due to the change of the air supply mode and the maximum frequency of the compressor, the indoor temperature may not only decrease but also judge whether the upper temperature of the room is less than the set temperature. If so, continue to operate in the current mode, otherwise continue to judge whether the lower temperature of the room is less than the set temperature within a certain range. If so, proceed to b, otherwise proceed to a. Each time the air supply mode is switched, it is necessary to judge whether the current temperature is less than a certain value and greater than another certain value, and then choose to operate in the current mode or enter the next stage or return to other stages according to the judgment.

[0202] Step d, the air conditioner supplies air in mode C at this time, and the compressor stops; and continues to determine whether the difference between the current upper temperature of the indoor unit's air inlet and the set temperature is less than or equal to the set threshold T1: If so, the air conditioner supplies air in mode C at this time, and the compressor stops, otherwise, enters step c; at this time, the lower indoor ambient temperature is lower than the set value within a certain range, and air is supplied in mode C, the compressor stops, and continues to determine whether the upper indoor temperature is lower than the set temperature within a certain range. If so, continue to operate in this manner, otherwise return to c.

[0203] In the scheme of the present invention, the upper and lower open-flow frequency conversion air conditioner can automatically control the movement of the upper and lower air guide components according to the difference between the upper and lower indoor temperatures and the set temperature under the above-mentioned air supply control method. While increasing the temperature rise and temperature drop rates, it can also reduce indoor temperature fluctuations, improve temperature control accuracy, and improve the problem of blowing discomfort.

[0204] Fig.12 The figure is a flow chart of the automatic air supply control process for heating of the present invention. The heating process is similar to the cooling process, except that the temperature is different. Fig.12 As shown in the figure, the automatic air supply control process for heating includes:

[0205] Step e, when the heating is turned on, the upper and lower parts of the inverter cabinet are opened to supply air in mode D, and the maximum operating frequency of the compressor is limited to D1; and in the process, it is determined whether the difference between the set temperature and the upper temperature of the current indoor unit air inlet is less than or equal to the set threshold value T1: if so, enter step f, otherwise the inverter air conditioner cabinet still supplies air in mode A, and the maximum operating frequency of the compressor is limited to A1.

[0206] Step f, the air conditioner now supplies air in mode E, and the maximum operating frequency of the compressor is limited to E1; and continue to determine whether the difference between the set temperature and the current lower temperature of the indoor unit air inlet is less than or equal to the set threshold value T2: if so, proceed to step g, otherwise, continue to determine whether the difference between the set temperature and the current upper temperature of the indoor unit air inlet is less than or equal to the set threshold value T1, if so, the air conditioner supplies air in mode E, and the maximum operating frequency of the compressor is limited to E1, otherwise, proceed to step e.

[0207] Step g, the air conditioner supplies air in mode F at this time, and the maximum operating frequency of the compressor is limited to F1; and continue to determine whether the difference between the set temperature and the upper temperature of the current indoor unit air inlet is less than or equal to the set threshold value T3: if so, enter step h, otherwise, continue to determine whether the difference between the set temperature and the lower temperature of the current indoor unit air inlet is less than or equal to the set threshold value T2, if so, the air conditioner supplies air in mode F, and the maximum operating frequency of the compressor is limited to F1, otherwise, continue to determine whether the difference between the set temperature and the upper temperature of the current indoor unit air inlet is less than or equal to the set threshold value T1, if so, enter step f, otherwise, enter step e.

[0208] Step h, the air conditioner supplies air in mode F at this time, and the compressor stops; and continues to determine whether the difference between the set temperature and the current temperature at the lower part of the indoor unit's air inlet is less than or equal to the set threshold T1: if so, the air conditioner supplies air in mode D at this time, and the compressor stops, otherwise, enter step g.

[0209] The scheme of the present invention proposes an automatic air supply control scheme for an upper and lower split air guide variable frequency air conditioner, which solves the problems of condensation and blowing discomfort caused by only adjusting the wind speed in related schemes, and improves the accuracy of temperature control while ensuring the air conditioning effect, thereby improving comfort. In the scheme of the present invention, multiple intervals are divided according to the difference between the upper and lower ambient temperatures and the set temperature of the room, and each temperature interval corresponds to a certain action mode of the upper and lower air guide plates. By limiting the maximum operating frequency of the compressor in different intervals, the greater the temperature difference, the higher the compressor operating frequency, and the smaller the temperature difference, the lower the compressor operating frequency, thereby ensuring the energy efficiency of the air conditioner while reducing the risk of condensation.

[0210] In some embodiments, the upper left and right wind guide assembly includes: upper left and right wind guide plates, which can be rotated to change their angles or moved to change their positions and can stay at the rotated angles or moved positions, and the running speed and staying time of the upper left and right wind guide plates at the staying angles or staying positions can be adjusted; the lower left and right wind guide assembly includes: lower left and right wind guide plates, which can be rotated to change their angles or moved to change their positions and can stay at the rotated angles or moved positions, and the running speed and staying time of the lower left and right wind guide plates at the staying angles or staying positions can be adjusted; the upper and lower wind guide assemblies include: upper and lower wind guide plates, which can be rotated to change their angles or moved to change their positions and can stay at the rotated angles or moved positions, and the running speed and staying time of the upper and lower wind guide plates at the staying angles or staying positions can be adjusted.

[0211] In the scheme of the present invention, the left and right air outlet ranges corresponding to the upper and lower temperature detection devices are defined as the left and right air guide plate sweeping ranges divided into five parts, corresponding to the temperature detection devices one by one from left to right, the upper left and right air guide plates correspond to the upper temperature detection devices, and the lower left and right air guide plates correspond to the lower temperature detection devices. The air outlet angles corresponding to the three middle temperature detection devices in the upper and lower parts are the angles corresponding to the center position of the air outlet range corresponding to the temperature detection devices, and the air outlet angles corresponding to the leftmost and rightmost temperature detection devices are the angles corresponding to the leftmost and rightmost of the corresponding air guide plate movement range. The air outlet range of the middle vertical temperature detection device is the upper and lower air guide plate sweeping range divided into five parts, corresponding to the temperature detection devices one by one from top to bottom, the air outlet angles corresponding to the three middle temperature detection devices in the vertical direction are the angles corresponding to the center position of the air outlet range corresponding to the temperature detection devices, and the air outlet angles corresponding to the uppermost and rightmost temperature detection devices are the angles corresponding to the uppermost and lowermost of the corresponding upper and lower air guide plate movement range. This section describes the definition of the air outlet range and air outlet angles.

[0212] In the scheme of the present invention, the temperature detection device is divided into three parts, namely, five temperature detection devices evenly distributed along the horizontal circumference of the air inlet at the upper part, five temperature detection devices evenly distributed along the horizontal circumference of the air inlet at the lower part, and five temperature detection devices evenly distributed along the vertical direction in the middle of the air inlet. Because the top and bottom two temperature detection devices of the vertically distributed temperature detection device are shared with the temperature detection devices in the middle of the upper horizontal distribution and the lower horizontal distribution, there are a total of thirteen temperature detection devices. Among them, the five temperature detection devices evenly distributed along the horizontal circumference of the air inlet at the upper part correspond to the upper left and right air guide plates; the five temperature detection devices evenly distributed along the horizontal circumference of the air inlet at the lower part correspond to the lower left and right air guide plates, and the five temperature detection devices evenly distributed along the vertical direction in the middle of the air inlet correspond to the upper and lower air guide plates.

[0213] Among them, the control unit 104, when the air conditioner is operated in the air supply mode of the two or more air guide components of the air outlet, combines the m upper air inlet temperatures with the upper average air inlet temperature, the n lower air inlet temperatures with the lower average air inlet temperature, and the p middle air inlet temperatures with the middle average air inlet temperature, to adjust at least one of the operating speeds and residence times of the two or more air guide components of the air outlet at the corresponding positions, including: when the air supply mode of the two or more air guide components of the air outlet is the first mode, the process of adjusting at least one of the operating speeds and residence times of the two or more air guide components of the air outlet at the corresponding positions in the first mode is as follows:

The wind deflector corresponding to the absolute value of the temperature difference of the first air inlet angle is recorded as the corresponding wind deflector; and the temperature detection device corresponding to the absolute value of the temperature difference of each air inlet angle among the m temperature detection devices, the n temperature detection devices, and the p temperature detection devices is recorded as the corresponding temperature detection device; wherein, taking the absolute value of the temperature difference of the first air inlet angle as an example, the first interval is the interval of α1≤t1, the second interval is the interval of t1<α1≤t2, the third interval is the interval of t3≤α1<t4, and the fourth interval is the interval of t4≤α1.

The specific functions and further processing of the control unit 104 refer to step S660.

[0227] In some embodiments, the control unit 104, when the air conditioner is operated in the air supply mode of the two or more air guide components of the air outlet, combines the m upper air inlet temperatures with the upper average air inlet temperature, the n lower air inlet temperatures with the lower average air inlet temperature, and the p middle air inlet temperatures with the middle average air inlet temperature, to adjust at least one of the operating speeds and residence times of the two or more air guide components of the air outlet at the corresponding positions, and also includes: when the air supply mode of the two or more air guide components of the air outlet is the second mode, the process of adjusting at least one of the operating speeds and residence times of the two or more air guide components of the air outlet at the corresponding positions in the second mode is as follows:

[0228] The control unit 104 is further configured to determine the absolute value of the difference between each of the m upper air inlet temperatures and the upper average air inlet temperature when the air supply mode of the two or more air guide components of the air outlet is the second mode, and record it as the absolute value of the temperature difference at the first air inlet angle. The specific functions and further processing of the control unit 104 refer to step S710.

[0229] The control unit 104 is further configured to determine the temperature interval to which the absolute value of the temperature difference of the first air inlet angle belongs within the set temperature range; wherein the temperature interval includes: a first interval, a second interval, a third interval and a fourth interval in which the temperature values ​​increase in sequence; and, the temperature detection device corresponding to the absolute value of the temperature difference of the first air inlet angle among the m temperature detection devices is recorded as a corresponding temperature detection device; wherein, taking the absolute value of the temperature difference of the first air inlet angle as an example, the first interval is an interval of α1≤t1, the second interval is an interval of t1<α1≤t2, the third interval is an interval of t3≤α1<t4, and the fourth interval is an interval of t4≤α1. The specific functions and further processing of the control unit 104 refer to step S720.

[0230] The control unit 104 is further configured to control the upper left and right air guide plates to increase their operating speed by a set first coefficient when they move to the air outlet range or air outlet angle corresponding to the corresponding temperature detection device if the absolute value of the temperature difference of the first air inlet angle is in the first interval; wherein the set first coefficient is, for example, 1. The specific functions and further processing of the control unit 104 refer to step S730.

[0231] The control unit 104 is further configured to control the upper left and right air guide plates to increase the operating speed by a set second coefficient when the upper left and right air guide plates move to the air outlet range corresponding to the air outlet range corresponding to the corresponding temperature detection device if the absolute value of the temperature difference of the first air inlet angle is in the second interval; wherein the set second coefficient is less than the set first coefficient, and the set first coefficient is 1.

[0232] The control unit 104 is further configured to control the upper left and right air guide plates to stay for a set first stay time when they move to the air outlet range corresponding to the air outlet range corresponding to the corresponding temperature detection device if the absolute value of the temperature difference of the first air inlet angle is within the third interval; wherein the set first stay time is, for example, 0.5s. The specific functions and further processing of the control unit 104 refer to step S750.

[0233] The control unit 104 is further configured to control the upper left and right air guide plates to stay for a set second dwell time when they move to the air outlet range corresponding to the air outlet range corresponding to the corresponding temperature detection device if the absolute value of the temperature difference of the first air inlet angle is in the fourth interval; wherein the set second dwell time is greater than the set first dwell time, and the set second dwell time is, for example, 1s. The specific functions and further processing of the control unit 104 refer to step S760.

[0234] Fig.14 FIG. 1 is a flow chart of the air supply process of mode B of the present invention. Fig.14 As shown, air supply is carried out in mode B: the upper left and right air guide components are running, the lower left and right air guide components stop running and are in the minimum air outlet position, the upper and lower air guide components are fixed at the upward air guide position, and the difference α1 between the temperature detected by the upper temperature detection device and the upper temperature of the inlet air is continuously judged during the process.

[0235] If α1≤t1, when the upper left and right air guide plates move to the air outlet range corresponding to the corresponding temperature detection device, the operating speed is increased by 1 times; if t1<α1≤t2, when the upper left and right air guide plates move to the air outlet range corresponding to the corresponding temperature detection device, the operating speed is increased by 0.5 times; if t3≤α1<t4, when the upper left and right air guide plates move to the air outlet angle corresponding to the corresponding temperature detection device, they stay for 0.5 seconds; if t4≤α1, when the upper left and right air guide plates move to the air outlet angle corresponding to the corresponding temperature detection device, they stay for 1 second.

[0236] In the solution of the present invention, this operating mode (mode B air supply) can effectively reduce the wind feeling at the bottom of the air conditioner, improve the uniformity of room temperature, and prevent excessive vertical temperature differences in the room.

[0237] Air supply in mode C: Both left and right air guide components stop running and are in the minimum air outlet position. The upper and lower air guide components are fixed in the upward air guide position. At this time, the temperature in the upper part of the room is close to the set temperature, and the temperature in the lower part of the room is slightly lower than the set temperature. The overall temperature of the room is closest to the set temperature. The air conditioner only blows out weak cold air from the upper part of the air outlet to keep the room temperature stable.

[0238] According to experiments, the difference T1 can be 0℃~2℃, preferably 1℃; the difference T2 can be -1℃~1℃, preferably 0℃; the difference T3 can be -3℃~-1℃, preferably -2℃. The t1 can be -1℃~0℃, preferably -0.5℃, the t2 can be -0.5℃~0℃, preferably -0.2℃, the t3 can be 0℃~0.5℃, preferably 0.2℃, and the t4 can be 0℃~1℃, preferably 0.5℃.

[0239] In the scheme of the present invention, this embodiment sets the maximum operating frequency of the compressor A1>B1>C1. Because the load of the air conditioner in the cooling room will gradually decrease, the maximum operating frequency of the compressor can be reduced, thereby saving energy. In the cooling mode, the air conditioner is in mode B air supply (the lower left and right air guide components are fixed at the minimum air outlet) and mode C air supply (the upper and lower left and right sweeping components are fixed at the minimum air outlet). The overall air volume will be reduced. If the frequency is not changed, the air outlet temperature will be reduced. When the air outlet temperature is lower than the indoor dew point temperature, there will be a risk of condensation. Therefore, in the cooling mode, when the air conditioner is in mode B air supply and mode C air supply, it is also necessary to gradually reduce the maximum operating frequency of the compressor and increase the air outlet temperature to avoid condensation.

[0240] Fig.16 Schematic diagram of the E-mode air supply process of the present invention. Fig.16 As shown, the E-mode air supply: the lower left and right air guide components are running, the upper left and right air guide components stop running and are at the minimum air outlet position, the upper and lower air guide components are fixed at the downward air guide position, and the difference β2 between the temperature detected by the lower temperature detection device and the lower temperature of the air inlet is continuously judged during the process. If β2≤t1, the lower left and right air guide plates move to the air outlet angle corresponding to the corresponding temperature detection device and stay for 1 second. If t1<β2≤t2, the lower left and right air guide plates move to the air outlet angle corresponding to the corresponding temperature detection device and stay for 0.5 seconds. If t3≤β2<t4, the lower left and right air guide plates move to the air outlet range corresponding to the corresponding temperature detection device, and the operating speed is increased by 0.5 times. If t4≤β2, the lower left and right air guide plates move to the air outlet range corresponding to the corresponding temperature detection device and the operating speed is increased by 1 times.

[0241] In the solution of the present invention, this operating mode (E-mode air supply) can effectively reduce the wind feeling on the upper part of the air conditioner, improve the uniformity of room temperature, and prevent excessive vertical temperature difference in the room.

[0242] F mode air supply: Both left and right air guide components stop running and are in the minimum air outlet position, and the upper and lower air guide components are fixed in the downward air guide position. At this time, the temperature in the lower part of the room is close to the set temperature, and the temperature in the upper part of the room is slightly higher than the set temperature. The overall temperature of the room is closest to the set temperature. The air conditioner only blows out weak hot air from the lower part of the air outlet to keep the room temperature stable.

[0243] In the solution of the present invention, this embodiment sets the maximum operating frequency of the compressor D1>E1>F1, mainly because the load in the air-conditioned heating room will gradually decrease, and the maximum operating frequency of the compressor can be reduced, thereby saving energy. The value range of the difference T1, T2 and T3 of the heating temperature is the same as that of the cooling, and the value range of the temperature t1, t2, t3 and t4 is the same as that of the cooling. The air outlet range corresponding to the temperature detection device and the air outlet angle corresponding to the temperature detection device are consistent with those of the cooling.

[0244] In the scheme of the present invention, an automatic air supply control scheme is adopted for the air conditioner with upper and lower separate air guides. The air supply mode of the air conditioner is adjusted according to the comparison between the ambient temperature of the upper and lower parts of the room and the set temperature, and the difference between the inlet temperature at different air inlet angles and the average temperature. This can achieve rapid temperature rise and drop, maintain high-precision temperature control and reduce the discomfort caused by the wind, thereby greatly improving the comfort of the air conditioner.

[0245] In the scheme of the present invention, the temperature control accuracy is high: according to the difference between the upper and lower temperatures of the room and the set temperature, a variety of air supply modes are used for alternating control to achieve a long-term temperature control effect with low temperature fluctuations. In the scheme of the present invention, energy saving: different maximum operating frequencies of the compressor are set to correspond to different room temperature differences to achieve energy saving effects, and reduce the risk of condensation in the cooling mode. In the scheme of the present invention, wind comfort: according to the difference between the ambient temperature and the set temperature, the air supply mode is adjusted, and when the ambient temperature is close to the set temperature, the problem of wind discomfort can be improved.
