Description

With the development of science and technology, the types of air conditioners have also become diverse, for example, wall-mounted air conditioners, vertical air conditioners, or cabinet machines, ceiling machines, etc. In particular, vertical air conditioners have a wider 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 up-down direction, the up-down direction of the air outlet is longer, and thus the air outlet temperature is not uniform, which further causes the temperature distribution in the indoor space to be uneven, especially in the vertical direction of the indoor space. In addition, due to the difference in the density of cold and hot air, cold air will sink in the indoor space, and hot air will rise in the indoor space, and thus when all types of air conditioners are running in the heating mode, hot air will gather in the upper space of the indoor space, which will also cause the temperature distribution in the indoor space to be uneven, all of which will reduce the user experience of using the vertical air conditioner.

[0107] 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 operating in the heating mode, and can compare the upper and lower ambient temperatures and adjust the rotation speeds of the upper and lower air distribution fans according to the comparison result; in the case where the upper ambient temperature is greater than the lower ambient temperature, the rotation speed of the upper air distribution fan is less than that of the lower air distribution fan. When the indoor unit is operating 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 can adjust the upper air distribution fan to make the flow rate of the air flow from the air outlet to the upper region space less than that of the air flow from the air outlet to the lower region space, so as to make the heating efficiency of the upper region space less than that of the lower region space, to make the lower ambient temperature equal to the upper ambient temperature, and effectively inhibit the uneven temperature distribution in the indoor space. In addition, the rotation of the upper air distribution fan can disturb the air flow to the upper region space, and the rotation of the lower air distribution fan can disturb the air flow 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.

[0108] In the present embodiment, in the case where the upper ambient temperature is less than the lower ambient temperature, the rotation speed of the upper air distribution fan is greater than that of the lower air distribution fan.

[0109] It can be understood that, as described in the foregoing embodiments, when the indoor unit is operating in the heating mode, if the temperature distribution is uneven, specifically, the temperature of the lower region space is higher than that of the upper region space, the control method of the present embodiment can adjust the upper air distribution fan to make the flow rate of the air flow from the air outlet to the upper region space greater than that of the air flow from the air outlet to the lower region space, so as to make the heating efficiency of the upper region space greater than that of the lower region space, to make the upper ambient temperature equal to the lower ambient temperature, and effectively inhibit the uneven temperature distribution in the indoor space.

[0110] In the embodiment, when the upper ambient temperature is equal to the lower ambient temperature, the rotation speed of the upper air distribution fan is equal to the rotation speed of the lower air distribution fan. The heating efficiency of the upper area space is kept the same as the heating efficiency of the lower area space, and the uniformity of the temperature distribution in the indoor space is ensured.

[0111] Figure 6 is a flow chart of a control method of the indoor unit of the vertical air conditioner according to another embodiment of the present application, with reference to Figure 6 In the embodiment, the control method of the indoor unit of the vertical air conditioner comprises:

[0112] In step S602, when the indoor unit of the vertical air conditioner operates in the heating mode, the upper ambient temperature of an upper area space in front of and above the indoor unit of the vertical air conditioner and the lower ambient temperature of a lower area space in front of and below the indoor unit of the vertical air conditioner are continuously detected.

[0113] In step S604, the upper ambient temperature and the lower ambient temperature are compared.

[0114] In step S606, the rotation speeds of the upper air distribution fan and the lower air distribution fan are adjusted according to the comparison result of the upper ambient temperature and the lower ambient temperature; and in the case that the upper ambient temperature is greater than the lower ambient temperature, the rotation speed of the upper air distribution fan is less than the rotation speed of the lower air distribution fan.

[0115] In step S608, the positions of the upper swing vane and the lower swing vane are adjusted according to the comparison result of the upper ambient temperature and the lower ambient temperature, and the adjusted upper swing vane and lower swing vane are located at positions for guiding the airflow flowing out of the air outlet to the area space with a relatively low ambient temperature between the upper area space and the lower area space.

[0116] In step S610, the left ambient temperature of a left area space on the left side of the indoor unit of the vertical air conditioner and the right ambient temperature of a right area space on the right side of the indoor unit of the vertical air conditioner are continuously detected.

[0117] In step S612, the left ambient temperature and the right ambient temperature are compared.

[0118] In step S614, the positions of the upper swing vane and the lower swing vane are adjusted according to the comparison result of the left ambient temperature and the right ambient temperature, and the adjusted upper swing vane and lower swing vane are located at positions for guiding the airflow flowing out of the air outlet to the area space with a relatively low ambient temperature between the left area space and the right area space.

[0119] 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.

[0120] Step S618, judging whether the average temperature is greater than the first preset temperature value of the indoor unit of the vertical air conditioner; if yes, executing step S620; if no, executing step S632.

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

[0122] Step S622, in the case that the upper ambient temperature is greater than the second preset temperature value, stopping power supply to the upper air distribution fan. After executing step S622, executing step S626.

[0123] Step S624, in the case that the upper ambient temperature is equal to the second preset temperature value, adjusting the speed gear of the upper air distribution fan to the low speed gear.

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

[0125] Step S628, in the case that the lower ambient temperature is greater than the second preset temperature value, stopping power supply to the lower air distribution fan.

[0126] Step S630, in the case that the lower ambient temperature is equal to the second preset temperature value, adjusting the speed gear of the lower air distribution fan to the low speed gear.

[0127] 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 flow to the area space with relatively low ambient temperature between the upper and lower area spaces, and thus the heating efficiency of the indoor unit of the vertical air conditioner in the heating mode can be ensured for the area space with low ambient temperature between the upper and lower area spaces, so as to further promote the leveling of the lower and upper ambient temperatures, and further effectively inhibit the uneven temperature distribution in the indoor space.

[0128] Moreover, through steps S610 to S614, the air flow from the air outlet can flow to the area space with relatively low ambient temperature between the left and right area spaces, and thus the heating efficiency of the indoor unit of the vertical air conditioner in the heating mode can be ensured for the area space with low ambient temperature between the left and right area spaces, so as to promote the leveling of the left and right ambient temperatures, and further effectively inhibit the uneven temperature distribution in the indoor space. In combination with steps S602 to S608, the uniformity of the ambient temperature in the indoor space can be effectively ensured.

[0129] 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 user sets for the upright air conditioner indoor unit to reach in the indoor space according to a large amount of test data. The first preset temperature value can be 50% of the second preset temperature value. When the average temperature of the indoor environment temperature is higher than the first preset temperature value during the heating mode of the upright air conditioner indoor unit, there is a high-temperature area space. The high-temperature area space is compared with the second preset temperature value to determine whether the high-temperature area space is an upper area space or a lower area space. When the temperature of the upper area space (or the lower area space) is higher than the second preset temperature value, the temperature of the upper area space (or the lower area space) is higher than the set temperature value of the upright air conditioner indoor unit, and the power supply to the upper air diffuser fan (or the lower air diffuser fan) is stopped to ensure the energy saving of the upright air conditioner indoor unit, and the air diffuser fan no longer affects the heating efficiency of the upper area space (or the lower area space) to ensure the comfort of the upper area space (or the lower area space). When the temperature of the upper area space (or the lower area space) is equal to the second preset temperature value, the temperature of the upper area space (or the lower area space) is equal to the set temperature value of the upright air conditioner indoor unit, and the speed of the upper air diffuser fan (or the lower air diffuser fan) is adjusted to a low speed to maintain the current heating efficiency of the upright air conditioner indoor unit in the upper area space (or the lower area space) and maintain the comfort of the upper area space (or the lower area space). The temperature of the upper area space (or the lower area space) is further leveled, and the uneven temperature distribution in the indoor space is further effectively inhibited.

[0130] In addition, the high-speed, medium-speed, and low-speed of the air diffuser fan can be different speed ranges (or speed values) that can be reached by the air diffuser fan, and the speed ranges (or speed values) corresponding to the high-speed, medium-speed, and low-speed are high-speed, medium-speed, and low-speed, respectively. After stopping the power supply to the upper air diffuser fan (or the lower air diffuser fan), if the airflow continues to flow out of the upper air outlet area (or the lower air outlet area), the upper air diffuser fan (or the lower air diffuser fan) will continue to rotate under the flow of the airflow, and the upper air diffuser fan (or the lower air diffuser fan) will still ensure that the airflow to the upper area space (or the lower area space) is disturbed, and the control method can also ensure the uniformity of the temperature in the upper area space (or the lower area 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, it is judged whether the average temperature is greater than or equal to the second preset temperature value; if not, that is, the average temperature is less than the second preset temperature value, the current speed of the upper and lower air distribution fans can be maintained, and the current positions of the upper and lower horizontal swing vanes and the upper and lower vertical swing vanes 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 executed.

[0133] Step S634, the speed gears of the upper and lower air distribution fans are adjusted to the low speed gears.

[0134] Step S636, the upper and lower horizontal swing vanes are controlled to rotate to positions for guiding the air flow flowing out of the air outlet to flow forward and downward.

[0135] Step S638, the upper and lower vertical swing vanes are controlled to swing in the horizontal direction.

[0136] It can be understood that, in the process of steps S632 to S634, when the average temperature is less than or equal to the first preset temperature value and greater than or equal to the second preset temperature value, that is, in the case of heating of the vertical air conditioner indoor unit, 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 comfortable, and then the control method of the embodiment can adjust the speed gears of the upper and lower air distribution fans to the low speed gears to maintain the current heating efficiency of the vertical air conditioner indoor unit on the upper and lower area spaces; and through step S636, the hot air flow can be guided to flow forward and downward out of the air outlet, and the hot air flow entering the bottom of the indoor space can gradually rise to ensure the uniformity of the temperature in the vertical direction of the indoor space. The above can maintain the comfort of the upper and lower area spaces and ensure the user experience.

[0137] And, through the implementation of step S638, the hot air flow flowing out of the vertical air conditioner indoor unit can be made to flow left and right, so as to ensure the uniformity of the temperature in the horizontal direction of the indoor space, and thus ensure the user experience.
