Description

[0002] Air conditioners, as electrical appliances for heating in winter and cooling in summer, have a growing number of users in the market. With the development of science and technology, the types of air conditioners have become diverse, such as wall-mounted air conditioners, vertical air conditioners, or cabinet machines, ceiling machines, etc. In particular, vertical air conditioners have a wide range of applications due to their sufficient air volume and aesthetic appearance. However, since the vertical air conditioner has an air outlet extending in the vertical direction, the vertical air outlet is relatively long, which may cause uneven air outlet temperature, further leading to uneven temperature distribution in the indoor space, especially in the vertical direction of the indoor space. In addition, due to the difference in density of cold and hot air, cold air will sink in the indoor space, and hot air will rise in the indoor space, so that when all types of air conditioners operate in cooling mode, cold air will gather in the lower space of the indoor space, which will also lead to uneven temperature distribution in the indoor space, and all of the above will reduce the user experience of using the vertical air conditioner.

[0105] Step S502, continuously detecting an upper ambient temperature of an upper region space in front of and above the indoor unit of the vertical air conditioner and a lower ambient temperature of a lower region space in front of and below the indoor unit of the vertical air conditioner when the indoor unit of the vertical air conditioner runs in the cooling mode.

[0106] Step S504, comparing the upper ambient temperature and the lower ambient temperature.

[0107] Step S506, adjusting the rotating speeds of the upper and lower air distribution fans according to the comparison result of the upper ambient temperature and the lower ambient temperature; wherein the rotating speed of the upper air distribution fan is greater than that of the lower air distribution fan when the upper ambient temperature is greater than the lower ambient temperature.

[0108] ​​The control method of the indoor unit of the vertical air conditioner can continuously detect the upper ambient temperature of the upper region space in front of and above the indoor unit and the lower ambient temperature of the lower region space in front of and below the indoor unit when the indoor unit is in the cooling mode, and can compare the upper ambient temperature and the lower ambient temperature, and adjust the rotating speed of the upper air distribution fan and the lower air distribution fan according to the comparison result. When the upper ambient temperature is greater than the lower ambient temperature, the rotating speed of the upper air distribution fan is greater than the rotating speed of the lower air distribution fan. When the indoor unit is in the cooling mode, if the temperature distribution is uneven, for example, the upper ambient temperature is higher than the lower ambient temperature, the control method can adjust the upper air distribution fan to make the flow rate of the airflow from the air outlet to the upper region space greater than the flow rate of the airflow from the air outlet to the lower region space, so that the cooling efficiency of the upper region space is greater than the cooling efficiency of the lower region space, to make the upper ambient temperature equal to the lower ambient temperature, and effectively prevent the temperature distribution from being uneven in the indoor space. In addition, the rotation of the upper air distribution fan can disturb the airflow to the upper region space, and the rotation of the lower air distribution fan can disturb the airflow to the lower region space, so that the control method can also ensure the uniformity of the temperature in the upper region space and the uniformity of the temperature in the lower region space. Therefore, the indoor space temperature distribution uniformity can be ensured, and the user experience can be improved.

[0109] In this embodiment, when the upper ambient temperature is less than the lower ambient temperature, the rotating speed of the upper air distribution fan is less than the rotating speed of the lower air distribution fan.

[0110] It can be understood that, as described in the foregoing embodiments, when the indoor unit is in the cooling mode, if the temperature distribution is uneven, specifically, the temperature of the lower region space is higher than the temperature of the upper region space, the control method can adjust the upper air distribution fan to make the flow rate of the airflow from the air outlet to the upper region space less than the flow rate of the airflow from the air outlet to the lower region space, so that the cooling efficiency of the upper region space is less than the cooling efficiency of the lower region space, to make the upper ambient temperature equal to the lower ambient temperature, and effectively prevent the temperature distribution from being uneven in the indoor space.

[0111] In this embodiment, when the upper ambient temperature is equal to the lower ambient temperature, the rotating speed of the upper air distribution fan is equal to the rotating speed of the lower air distribution fan. The cooling efficiency of the upper region space is continuously ensured to be the same as the cooling efficiency of the lower region space, and the temperature distribution uniformity in the indoor space is ensured.

[0112] Figure 6 is a flow chart of the control method of the indoor unit of the vertical air conditioner according to another embodiment of the present application, with reference to Figure 6In the embodiment, the control method of the standing air conditioner indoor unit comprises:

[0113] In step S602, in the case that the standing air conditioner indoor unit operates in the cooling mode, the upper ambient temperature of the upper area space in front of and above the standing air conditioner indoor unit and the lower ambient temperature of the lower area space in front of and below the standing air conditioner indoor unit are continuously detected.

[0114] In step S604, the upper ambient temperature and the lower ambient temperature are compared.

[0115] In step S606, the rotating speeds of the upper and lower air distribution fans are adjusted according to the comparison result of the upper ambient temperature and the lower ambient temperature; wherein, in the case that the upper ambient temperature is greater than the lower ambient temperature, the rotating speed of the upper air distribution fan is greater than the rotating speed of the lower air distribution fan.

[0116] In step S608, the positions of the upper and lower horizontal swing leaves are adjusted according to the comparison result of the upper ambient temperature and the lower ambient temperature, wherein, the adjusted upper and lower horizontal swing leaves are located in the position that guides the airflow flowing out of the air outlet to the area space with relatively high ambient temperature between the upper area space and the lower area space.

[0117] In step S610, the left ambient temperature of the left area space in the left side of the standing air conditioner indoor unit and the right ambient temperature of the right area space in the right side of the standing air conditioner indoor unit are continuously acquired.

[0118] In step S612, the left ambient temperature and the right ambient temperature are compared.

[0119] In step S614, the rotating positions of the upper and lower vertical swing leaves are adjusted according to the comparison result of the left ambient temperature and the right ambient temperature, wherein, the adjusted upper and lower horizontal swing leaves are located in the position that guides the airflow flowing out of the air outlet to the area space with relatively high ambient temperature between the left area space and the right area space.

[0120] In step S616, the average temperature of the upper ambient temperature, the lower ambient temperature, the left ambient temperature and the right ambient temperature is calculated.

[0121] In step S618, it is judged whether the average temperature is less than the first preset temperature value of the standing air conditioner indoor unit; if yes, step S620 is executed; if no, step S632 can be executed.

[0122] In step S620, the upper ambient temperature is compared with the second preset temperature value, wherein, the first preset temperature value is less than the second preset temperature value.

[0123] In step S622, in the case that the upper ambient temperature is less than the second preset temperature value, the power supply to the upper air distribution fan is stopped. After step S622 is executed, step S626 is executed.

[0124] Step S624, in the case that the upper ambient temperature is equal to the second preset temperature value, the rotating speed of the upper air distribution fan is adjusted to a low speed.

[0125] S626, the lower ambient temperature is compared with the second preset temperature value.

[0126] Step S628, in the case that the lower ambient temperature is less than the second preset temperature value, the power supply to the lower air distribution fan is stopped.

[0127] Step S630, in the case that the lower ambient temperature is equal to the second preset temperature value, the rotating speed of the lower air distribution fan is adjusted to a low speed.

[0128] It should be understood that, through the adjustment of the upper and lower swing leaves in step S608, the air flow from the air outlet can be made to flow into the region space with relatively high ambient temperature between the upper region space and the lower region space, and thus the vertical air conditioner indoor unit in the cooling mode can ensure the cooling efficiency of the region space with high ambient temperature between the upper region space and the lower region space, so as to further promote the equalization of the upper ambient temperature and the lower ambient temperature, and further effectively inhibit the uneven temperature distribution in the indoor space.

[0129] And, through steps S610 to S614, the air flow from the air outlet can be made to flow into the region space with relatively high ambient temperature between the left region space and the right region space, and thus the vertical air conditioner indoor unit in the cooling mode can ensure the cooling efficiency of the region space with high ambient temperature between the left region space and the right region space, so as to promote the equalization of the left ambient temperature and the right ambient temperature, and further effectively inhibit the uneven temperature distribution in the indoor space. And in combination with steps S602 to S608, the uniformity of the ambient temperature in the indoor space can be effectively ensured.

[0130] The second preset temperature value can be a temperature value that the user sets for the upright air conditioner indoor unit to reach in the indoor space, or a temperature value that the person skilled in the art directly sets for the upright air conditioner indoor unit to reach in the indoor space after a large number of test data. The first preset temperature value can be 50% of the second preset temperature value. Through the implementation of steps S616 to S630, when the average temperature of the indoor environment temperature in the cooling mode of the upright air conditioner indoor unit is lower than the first preset temperature value, that is, there is a region space with very low environmental temperature, the upper environmental temperature is compared with the second preset temperature value to detect whether the region space with very low environmental temperature is the upper region space or the lower region space. When the environmental temperature of the upper region space (or the lower region space) is lower than the second preset temperature value, it indicates that the environmental temperature of the upper region space (or the lower region space) is lower than the set temperature value of the upright air conditioner indoor unit, and then the power supply to the upper air distribution fan (or the lower air distribution fan) can be stopped to ensure the energy saving of the upright air conditioner indoor unit, and the air distribution fan no longer affects the cooling efficiency of the upper region space (or the lower region space) to ensure the comfort of the upper region space (or the lower region space). When the environmental temperature of the upper region space (or the lower region space) is equal to the second preset temperature value, it indicates that the environmental temperature of the upper region space (or the lower region space) is equal to the set temperature value of the upright air conditioner indoor unit, and the speed gear of the upper air distribution fan (or the lower air distribution fan) can be adjusted to a low speed gear to maintain the current cooling efficiency of the upright air conditioner indoor unit on the upper region space (or the lower region space) and maintain the comfort of the upper region space (or the lower region space). Further, the upper environmental temperature and the lower environmental temperature are leveled, and the uneven temperature distribution in the indoor space is further effectively inhibited.

[0131] In addition, the high-speed gear, the medium-speed gear, and the low-speed gear of the speed gear of the air distribution fan can be different speed ranges (or speed values) that the person skilled in the art pre-divides according to the rated speed range that the air distribution fan can reach, and the speed ranges (or speed values) corresponding to the speed gears are high-speed gear, medium-speed gear, and low-speed gear in turn from large to small. After stopping the power supply to the upper air distribution fan (or the lower air distribution fan), if the airflow in the upper air outlet area (or the lower air outlet area) continues to flow out, the upper air distribution fan (or the lower air distribution fan) will continue to rotate under the flow of the airflow, and the upper air distribution fan (or the lower air distribution fan) will still ensure that the airflow flowing to the upper region space (or the lower region space) is disturbed, and the control method can also ensure the uniformity of the temperature in the upper region space (or the lower region space).

[0132] In step S608, the upper horizontal swing blade is adjusted to a position for guiding the air flow from the upper air outlet area to flow forward and upward, and the lower horizontal swing blade is adjusted to a position for guiding the air flow from the lower air outlet area to flow forward and downward. In this way, the air flow flows through the upper area space and the lower area space regardless of the comparison result of the upper ambient temperature and the lower ambient temperature, and the air flow flowing out of the air outlet is prevented from blowing straight forward, thereby achieving the straight blowing prevention function.

[0133] With reference to Figure 6 In the embodiment, in the case where the average temperature is greater than or equal to the first preset temperature value, the control method further comprises:

[0134] In step S632, it is determined whether the average temperature is less than or equal to the second preset temperature value. If not, that is, in the case where the average temperature is greater than the second preset temperature value, the current rotating speed of the upper and lower air distribution fans is maintained, and the current positions of the upper and lower horizontal swing blades and the upper and lower vertical swing blades are maintained, so that the vertical air conditioner indoor unit continues to promote the uniformity of the ambient temperature of the indoor space. If yes, step S634 is performed.

[0135] In step S634, the rotating speed gears of the upper and lower air distribution fans are adjusted to the low speed gears.

[0136] In step S636, the upper horizontal swing blade is controlled to rotate to a position for guiding the air flow from the upper air outlet area to flow forward and upward, and the lower horizontal swing blade is controlled to rotate to a position for guiding the air flow from the lower air outlet area to flow forward and downward.

[0137] In step S638, the upper vertical swing blade is controlled to rotate to a position for guiding the air flow from the upper air outlet area to flow left and forward, and the lower vertical swing blade is controlled to rotate to a position for guiding the air flow from the lower air outlet area to flow right and forward, or the upper vertical swing blade is controlled to rotate to a position for guiding the air flow from the upper air outlet area to flow right and forward, and the lower vertical swing blade is controlled to rotate to a position for guiding the air flow from the lower air outlet area to flow left and forward.

[0138] It can be understood that, in the process of implementing steps S632 to S636, in the case where the average temperature is greater than or equal to the first preset temperature value and the average temperature is less than or equal to the second preset temperature value, that is, in the case where the vertical air conditioner indoor unit is in cooling, the ambient temperature of the indoor space reaches the set temperature value and is not too low, at this time, the temperature of the indoor space is relatively comfortable, and therefore, the control method of the embodiment can adjust the rotating speed gears of the upper and lower air distribution fans to the low speed gears, so as to maintain the current cooling efficiency of the vertical air conditioner indoor unit on the upper area space and the lower area space. The comfort of the upper area space and the lower area space is maintained, and the user experience is ensured.

[0139] And, by implementing step S638, the vertical air conditioner indoor unit can be prevented from blowing air to the front, so as to realize the direct blowing prevention function and ensure the user experience.
