Furthermore, when the vertical air conditioner indoor unit is running in the heating mode, if the temperature distribution is uneven, for example, the upper ambient temperature is higher than the lower ambient temperature, the control method of the present invention can adjust the upper diffuser fan to at least make the flow rate of the airflow flowing from the air outlet into the upper area space less than the flow rate of the airflow flowing from the air outlet into the lower area space, thereby making the heating efficiency of the upper area space less than the heating efficiency of the lower area space, so as to promote the lower ambient temperature to be equal to the upper ambient temperature, and effectively suppress the occurrence of uneven temperature distribution in the indoor space. Furthermore, since the rotation of the upper diffuser fan can disturb the airflow flowing to the upper area space, and the rotation of the lower diffuser fan can disturb the airflow flowing to the lower area space, the control method can also ensure the uniformity of temperature at various locations in the upper area space and the uniformity of temperature at various locations in the lower area space. Therefore, the present invention can ensure the uniformity of temperature distribution in the indoor space and improve user experience.

[0108] In this embodiment, when the upper ambient temperature is lower than the lower ambient temperature, the rotation speed of the upper diffuser fan is higher than the rotation speed of the lower diffuser fan.

[0109] It can be understood that, as described in the aforementioned embodiment, when the vertical air-conditioning indoor unit is operating in the heating mode, if uneven temperature distribution occurs, specifically, when the temperature of the lower area space is higher than that of the upper area space, the control method of this embodiment can adjust the upper diffusion fan to at least make the flow rate of the airflow flowing from the air outlet to the upper area space greater than the flow rate of the airflow flowing from the air outlet to the lower area space, thereby making the heating efficiency of the upper area space greater than the heating efficiency of the lower area space, so as to make the upper ambient temperature equal to the lower ambient temperature, and effectively suppress the occurrence of uneven temperature distribution in the indoor space.

[0110] In this embodiment, when the upper ambient temperature is equal to the lower ambient temperature, the rotation speed of the upper diffuser fan is equal to the rotation speed of the lower diffuser fan, so as to continuously ensure that the heating efficiency of the upper zone space is the same as the heating efficiency of the lower zone space, and ensure the uniformity of temperature distribution in the indoor space.

[0111] Figure 6 is a flow chart of a control method for a vertical air conditioner indoor unit according to another embodiment of the present invention, referring to Figure 6 In this embodiment, the control method of the vertical air conditioner indoor unit includes:

[0112] Step S602: When the vertical air conditioner indoor unit operates in heating mode, the upper ambient temperature of the upper area space located above the front of the vertical air conditioner indoor unit and the lower ambient temperature of the lower area space located below the front of the vertical air conditioner indoor unit in the indoor space are continuously detected.

[0113] Step S604, comparing the upper ambient temperature and the lower ambient temperature.

[0114] Step S606, adjusting the rotation speeds of the upper diffuser fan and the lower diffuser fan according to the comparison result of the upper ambient temperature and the lower ambient temperature; wherein, when the upper ambient temperature is greater than the lower ambient temperature, the rotation speed of the upper diffuser fan is less than the rotation speed of the lower diffuser fan.

[0115] Step S608, adjusting the rotation positions of the upper swing blade and the lower swing blade according to the comparison result of the upper ambient temperature and the lower ambient temperature, wherein the adjusted upper swing blade and the lower swing blade are in a position to guide the airflow flowing out of the air outlet to flow to the area space with relatively low ambient temperature between the upper area space and the lower area space.

[0116] Step S610, continuously acquiring the left ambient temperature of the left zone space located on the left side of the vertical air conditioner indoor unit and the right ambient temperature of the right zone space located on the right side of the vertical air conditioner indoor unit in the indoor space.

[0117] Step S612, comparing the left ambient temperature and the right ambient temperature.

[0118] Step S614, adjusting the rotation positions of the upper vertical swing blades and the lower vertical swing blades according to the comparison result of the left ambient temperature and the right ambient temperature, wherein the adjusted upper horizontal swing blades and the lower horizontal swing blades are in a position to direct the airflow flowing out of the air outlet to the regional space with relatively low ambient temperature between the left regional space and the right regional space.

[0119] Step S616, calculating the average temperature of the upper ambient temperature, the lower ambient temperature, the left ambient temperature and the right ambient temperature.

[0120] Step S618, determining whether the average temperature is greater than a first preset temperature value of the vertical air conditioner indoor unit; if so, executing step S620; if not, executing step S632.

[0121] Step S620, comparing the upper ambient temperature with a second preset temperature value, wherein the first preset temperature value is greater than the second preset temperature value.

[0122] Step S622: When the upper ambient temperature is greater than the second preset temperature value, stop supplying power to the upper diffuser fan. After executing step S622, execute step S626.

[0123] Step S624, when the upper ambient temperature is equal to the second preset temperature value, adjusting the speed gear of the upper diffuser fan to a low speed gear.

[0124] Step S626, comparing the lower ambient temperature with the second preset temperature value.

[0125] Step S628: when the lower ambient temperature is greater than a second preset temperature value, stop supplying power to the downward diffusion fan.

[0126] Step S630: When the lower ambient temperature is equal to the second preset temperature value, adjust the speed gear of the lower diffuser fan to a low speed gear.

[0127] It should be understood that, by adjusting the upper and lower swing blades in step S608, the airflow flowing out of the air outlet can flow as much as possible to the regional space with relatively low ambient temperature between the upper regional space and the lower regional space, and then the vertical air-conditioning indoor unit in the heating mode can ensure the heating efficiency of the regional space with low ambient temperature between the upper regional space and the lower regional space, so as to further promote the equality of the lower ambient temperature and the upper ambient temperature, and further effectively suppress the occurrence of uneven temperature distribution in the indoor space.

[0128] Furthermore, through steps S610 to S614, the airflow flowing out of the air outlet can flow as much as possible to the area space with relatively low ambient temperature between the left area space and the right area space, and then the vertical air conditioner indoor unit can ensure the heating efficiency of the area space with low ambient temperature between the left area space and the right area space in the heating mode, so as to make the left ambient temperature and the right ambient temperature equal, and further effectively suppress the occurrence of uneven temperature distribution in the indoor space. And combined with steps S602 to S608, the uniformity of the ambient temperature in the indoor space can be effectively guaranteed.

[0129] Furthermore, the second preset temperature value may be a temperature value set by the user for the vertical air conditioner indoor unit to cause the indoor space to reach, or may be a temperature value set directly by a person skilled in the art based on a large amount of test data for the vertical air conditioner to cause the indoor space to reach; the first preset temperature value may be one-hundredth to fifty percent of the second preset temperature value. Through the implementation of steps S616 to S630, when the vertical air conditioner indoor unit operates in a heating mode causing the average temperature of the indoor environment to be higher than the first preset temperature value, that is, there is a regional space with a very high ambient temperature, the upper ambient temperature is respectively compared with the second preset temperature value to detect whether the regional space with a very high ambient temperature is an upper regional space or a lower regional space. Moreover, when the ambient temperature of the upper area space (or the lower area space) is higher than the second preset temperature value, it indicates that the ambient temperature of the upper area space (or the lower area space) is higher than the set temperature value of the vertical air conditioner indoor unit, and then the power supply to the upper diffuser fan (or the lower diffuser fan) can be stopped to ensure the energy saving of the vertical air conditioner indoor unit, and the diffuser fan no longer affects the heating efficiency of the upper area space (or the lower area space), ensuring the comfort of the upper area space (or the lower area space); when the ambient temperature of the upper area space (or the lower area space) is equal to the second preset temperature value, it indicates that the ambient temperature of the upper area space (or the lower area space) is equal to the set temperature value of the vertical air conditioner indoor unit, and the speed gear of the upper diffuser fan (or the lower diffuser fan) can be adjusted to a low speed gear to maintain the current heating efficiency of the vertical air conditioner indoor unit to the upper area space (or the lower area space), and maintain the comfort of the upper area space (or the lower area space). Further promote the equalization of the upper ambient temperature and the lower ambient temperature, and further effectively suppress the occurrence of uneven temperature distribution in the indoor space.

[0130] In addition, the high speed gear, medium speed gear and low speed gear of the speed gear of the diffuser fan can be different speed ranges (or speed values) pre-divided by technicians in this field according to the rated speed range that the diffuser fan can reach, and the speed ranges (or speed values) corresponding to each speed gear are high speed gear, medium speed gear and low speed gear from large to small. And after stopping the power supply to the upward diffuser fan (or the lower diffuser fan), if there is airflow continuing to flow out of the upper air outlet area (or the lower air outlet area), the upper diffuser fan (or the lower diffuser fan) will continue to rotate under the flow of airflow, and then the upper diffuser fan (or the lower diffuser fan) will still ensure the disturbance of the airflow flowing to the upper regional space (or the lower regional space), and then the control method can also ensure the uniformity of temperature at various locations in the upper regional space (or the lower regional space).

[0131] In this embodiment, when the average temperature is less than or equal to the first preset temperature value, the control method further includes:

[0132] Step S632, determine whether the average temperature is greater than or equal to the second preset temperature value; if not, that is, when the average temperature is less than the second preset temperature value, the current rotation speeds of the upper diffuser fan and the lower diffuser fan can be maintained, and the current positions of the upper horizontal swing blade, the lower horizontal swing blade, the upper vertical swing blade, and the lower vertical swing blade can be maintained, so that the vertical air conditioner indoor unit continues to promote the uniformity of the ambient temperature of the indoor space. If so, execute step S634.

[0133] Step S634, adjusting the speed gears of the upper diffuser fan and the lower diffuser fan to a low speed gear.

[0134] Step S636, controlling the upper and lower lateral swing blades to rotate to a position to guide the airflow flowing out of the air outlet to flow forward and downward.

[0135] Step S638, controlling the upper vertical swing blade and the lower vertical swing blade to swing in the horizontal direction.

[0136] It can be understood that during the implementation of step S632 to step S634, when the average temperature is less than or equal to the first preset temperature value, and the average temperature is greater than or equal to the second preset temperature value, that is, when the vertical air conditioner indoor unit is heating, the ambient temperature of the indoor space reaches the set temperature value and is not too high. At this time, the temperature of the indoor space is relatively comfortable. Furthermore, the control method of this embodiment can adjust the speed gears of the upper diffuser fan and the lower diffuser fan to the low speed gear to maintain the current heating efficiency of the vertical air conditioner indoor unit to the upper and lower regional spaces; and through step S636, the hot air flow can be prompted to flow out of the outlet to the front and bottom, and the hot air flow entering the bottom of the indoor space will gradually rise to ensure the uniformity of the temperature in the vertical direction of the indoor space. All of the above can maintain the comfort of the upper and lower regional spaces and ensure user experience.

[0137] Furthermore, by implementing step S638, the hot air flow out of the vertical air-conditioning indoor unit can be directed to the left and right to ensure the uniformity of the temperature in the horizontal direction of the indoor space, thereby ensuring the user experience.
