[0030] an integrated air conditioner 100,

[0031] a shell 10, a first air inlet 11, a second air inlet 12, a first air outlet 13, a second air outlet 14,

[0032] a first air duct 20, a second air duct 30, an external fan 50, an internal fan 60, a condenser 70, an evaporator 80, a compressor 90. DETAILED DESCRIPTION

[0033] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] The following is for reference. Figures 1-5 An integrated air conditioner 100 and a control method for the integrated air conditioner 100 according to an embodiment of the present invention are described. The integrated air conditioner 100 can be detachably mounted on a window frame via a mounting mechanism, meaning that the integrated air conditioner 100 can be used as a window air conditioner. Alternatively, the integrated air conditioner 100 can operate independently, in which case it can be used as a portable air conditioner.

[0035] like Figures 2-5 As shown, the integrated air conditioner 100 according to an embodiment of the present invention includes: a compressor 90, an outdoor fan 50, and a controller. Further, the integrated air conditioner 100 may also include: a housing 10, a first air duct component 20, a second air duct component 30, a condenser 70, and an evaporator 80. The housing 10 is provided with a first air inlet 11, a second air inlet 12, a first air outlet 13, and a second air outlet 14. The first air duct component 20 is connected to the first air inlet 11 and the first air outlet 13, respectively, and the second air duct component 30 is connected to the second air inlet 12 and the second air outlet 14, respectively. Furthermore, the compressor 90, the outdoor fan 50, the controller, the condenser 70, the evaporator 80, the first air duct component 20, and the second air duct component 30 are all disposed within the housing 10.

[0036] Furthermore, the compressor 90 is connected to the condenser 70, the condenser 70 to the evaporator 80, and the compressor 90 to the evaporator 80 by pipelines. Refrigerant can be filled into the pipelines. The compressor 90 can compress the refrigerant from a low-temperature, low-pressure gas into a high-temperature, high-pressure gas. The refrigerant gas can flow from the compressor 90 to the condenser 70. The high-temperature, high-pressure refrigerant gas can be condensed into a refrigerant liquid in the condenser 70. The condenser 70 can transfer the heat in the refrigerant to the outdoor environment.

[0037] Furthermore, a throttling valve can be connected between the condenser 70 and the evaporator 80. This valve reduces the pressure of the refrigerant liquid in the condenser 70. After throttling, the refrigerant transforms into a low-temperature, low-pressure liquid. This low-temperature, low-pressure refrigerant liquid can flow to the evaporator 80, where it absorbs heat and evaporates to become a low-temperature, low-pressure refrigerant gas. The evaporator 80 can exchange heat with the air flowing into the room, thus cooling the air and lowering the indoor temperature. The low-temperature, low-pressure refrigerant gas can then flow from the evaporator 80 to the compressor 90, completing the refrigeration cycle in the air conditioner. It should be noted that a heating cycle in the air conditioner can be achieved by driving the refrigerant to flow in the reverse direction.

[0038] Meanwhile, the condenser 70 can be set near the first air inlet 11, and the evaporator 80 can be set near the second air inlet 12. By integrating the first air duct component 20 and the second air duct component 30 into the same casing 10, the first air inlet 11 and the first air outlet 13 of the first air duct component 20 face the outside, and the second air inlet 12 and the second air outlet 14 of the second air duct component 30 are connected to the indoor space. The first air duct component 20 limits the outdoor heat exchange of the integrated air conditioner 100, and the second air duct component 30 limits the indoor heat exchange of the integrated air conditioner 100. The overall cooling of the space where the integrated air conditioner 100 is arranged can be realized. The integrated air conditioner 100 can be moved between multiple rooms by disengaging the installation mechanism from the window frame. When users need to move, they can also move and transport the integrated air conditioner 100 themselves.

[0039] In addition, the integrated air conditioner 100 is also equipped with an indoor fan 60 and an outdoor fan 50. The outdoor fan 50 can be installed in the first air duct component 20, and the indoor fan 60 can be installed in the second air duct component 30. During the operation of the integrated air conditioner 100, the outdoor fan 50 in the first air duct component 20 generates suction to draw airflow in through the first air inlet 11, and after exchanging heat with the condenser 70, it is discharged through the first air outlet 13. The indoor fan 60 in the second air duct component 30 generates suction to draw airflow in through the second air inlet 12, and after exchanging heat with the evaporator 80, it is discharged through the second air outlet 14, thereby achieving cooling or heating of part of the air in the indoor space (forming a portable air conditioner) or all of the air (forming a window-mounted air conditioner).

[0040] Furthermore, such as Figures 1-5The shell 10 can include a front shell, a rear shell, a top shell, a bottom shell, side plates and the like. The front shell can include a plurality of plate bodies. The second air outlet 14 can be arranged on the front shell. The second air inlet 12 can be arranged on the side plates on both sides of the front shell. The first air inlet 11 and the second air outlet 14 can be arranged on the rear shell. The first air duct 20 and the second air duct 30 can be symmetrically arranged in the shell 10, so as to improve the compactness of the integrated air conditioner 100 and reduce the space occupation of the air conditioner. The air inlet filter screen can be arranged on the first air inlet 11 and the second air inlet 12. The flow guide grille can be arranged on the second air outlet 14. The evaporator 80 and the condenser 70 are in communication with the compressor 90. The compressor 90 is also arranged in the shell 10.

[0041] Further, as shown in Figures 2-4 , the condenser 70 extends from top to bottom to the bottom wall of the shell 10. The lower portion of the evaporator 80 is provided with a placement space for placing the compressor 90. That is, the upper end of the second air duct 30 is arranged adjacent to the top shell, and the lower end is arranged adjacent to the bottom shell, so that the second air outlet 14 can be arranged larger, the air outlet area is improved, and the air outlet effect is improved. The evaporator 80 is opposite to the second air inlet 12. The second air inlet 12 can also be arranged larger, so as to improve the heat exchange efficiency and improve the use experience of the integrated air conditioner 100. The bottom end of the first air duct 20 is spaced apart from the bottom shell to define a placement space. The compressor 90 is arranged in the placement space, so that the arrangement position of the compressor 90 is more reasonable, and the arrangement of the internal components of the shell 10 is more compact, and the space occupation of the shell 10 is reduced.

[0042] The bottom of the compressor 90 and the bottom of the outer fan 50 are fixed by the same fixing position. The fixing position for fixing the compressor 90 and the outer fan 50 can be arranged on the first structure. The first structure can be arranged in the shell 10. The central axis of the compressor 90 and the central axis of the outer fan 50 can be arranged in the height direction of the integrated air conditioner 100. That is, the central axis of the compressor 90 and the central axis of the outer fan 50 can be arranged in parallel.

[0043] In addition, the rotation direction of the compressor 90 is opposite to the rotation direction of the outer fan 50. For example, when the compressor 90 rotates forward, the outer fan 50 can rotate reversely. Or when the compressor 90 rotates reversely, the outer fan 50 can rotate forward. It should be noted that the forward rotation direction of the compressor 90 can refer to the clockwise direction in Figure 5 , and the reverse rotation direction of the compressor 90 can refer to the counterclockwise direction in Figure 5 . Correspondingly, the forward rotation direction of the outer fan 50 can refer to the clockwise direction in Figure 5 , and the reverse rotation direction of the outer fan 50 can refer to the counterclockwise direction in Figure 5 .

[0044] When the compressor 90 is working, it can generate vibration, which can be transmitted to the housing 10 through the first structural component. Similarly, when the external fan 50 is working, it can also generate vibration, which can be transmitted to the housing 10 through the first structural component. In other words, the compressor 90 can act as a vibration excitation source, and the external fan 50 can act as another vibration excitation source. By controlling the rotation direction of the compressor 90 to be opposite to that of the external fan 50, the vibration generated by the compressor 90 and the vibration generated by the external fan 50 can be superimposed in opposite directions. The vibration generated by the external fan 50 can cancel the vibration generated by the compressor 90, reducing the amplitude of the vibration transmitted to the housing 10. This reduces the vibration of the housing 10 and, consequently, the noise generated by the vibration of the housing 10.

[0045] In addition, the controller is used to acquire the base acceleration of the compressor 90 when it is determined that the compressor 90 is operating at increased frequency, and to determine the target speed of the outdoor fan 50 based on the base acceleration, and to control the outdoor fan 50 to operate at the target speed. When the compressor 90 is operating at increased frequency, the speed of the compressor 90 increases, and the vibration generated by the compressor 90 will cause greater noise to be generated in the casing 10. By controlling the outdoor fan 50 to operate at the target speed, the vibration generated by the outdoor fan 50 can be effectively offset by the vibration generated by the compressor 90, thereby reducing the need for vibration damping structures between the first structural component and the casing 10, and thus reducing the production cost of the integrated air conditioner 100.

[0046] Therefore, when the compressor 90 is operating at increased frequency, the outdoor fan 50 is controlled by the controller to run at the target speed. The reverse vibration generated by the outdoor fan 50 during operation can counteract the vibration generated by the compressor 90, thereby reducing the vibration transmitted to the casing 10 of the integrated air conditioner 100. Compared with the prior art, this can reduce the noise generated by the casing 10 of the integrated air conditioner 100, thereby improving the product quality of the integrated air conditioner 100 and improving the user's experience with the integrated air conditioner 100.

[0047] like Figure 1 As shown in the embodiment of the present invention, the control method for an integrated air conditioner can be the integrated air conditioner described above. That is, the control method can control the operation of the integrated air conditioner described above. The integrated air conditioner includes a compressor and an outdoor fan. Both the compressor and the outdoor fan can be housed within the casing as described above. The base of the compressor and the bottom of the outdoor fan are fixed at the same fixing point. Specifically, the base of the compressor and the bottom of the outdoor fan can both be fixed to a first structural member, which can be housed within the casing. The central axis of the compressor and the central axis of the outdoor fan can both extend in the height direction of the integrated air conditioner, and the central axes of the compressor and the outdoor fan can be arranged parallel to each other.

[0048] and the rotation direction of the compressor is opposite to the rotation direction of the outer fan, the outer fan can rotate reversely when the compressor rotates forwardly, or the outer fan can rotate forwardly when the compressor rotates reversely. The control method comprises the following steps:

[0049] S1, determining that the compressor is in frequency conversion operation, acquiring the foot acceleration of the compressor. Wherein, the integrated air conditioner is provided with a controller, when it is determined that the compressor is in frequency conversion operation, the controller is used to acquire the foot acceleration of the compressor.

[0050] S2, determining the target rotating speed of the outer fan according to the foot acceleration.

[0051] S3, controlling the outer fan to run at the target rotating speed.

[0052] Wherein, when the compressor is working, the compressor can generate vibration, which can be transmitted to the shell through the first structural member, and when the outer fan is working, the outer fan can generate vibration, which can be transmitted to the shell through the first structural member, that is, the compressor can act as a vibration excitation source, and the outer fan can act as another vibration excitation source, by controlling the rotation direction of the compressor to be opposite to the rotation direction of the outer fan, the vibration generated by the compressor and the vibration generated by the outer fan can be superimposed reversely, the vibration generated by the outer fan can offset the vibration generated by the compressor, and the amplitude of the vibration transmitted to the shell is reduced, thereby the vibration of the shell can be reduced, and further the noise generated by the vibration of the shell can be reduced.

[0053] When the controller acquires the foot acceleration of the compressor, the controller can determine the target rotating speed of the outer fan according to the foot acceleration when the compressor is in frequency conversion operation, and the controller can control the outer fan to run at the target rotating speed. Wherein, when the compressor is in frequency conversion operation, the rotating speed of the compressor is increased, and the vibration generated by the compressor will cause the shell to generate greater noise, by controlling the outer fan to run at the target rotating speed through the controller, the reverse vibration generated by the outer fan can be matched with the vibration of the compressor, the vibration generated by the outer fan can effectively offset the vibration generated by the compressor, thereby the damping structure between the first structural member and the shell can be reduced, and further the production cost of the integrated air conditioner can be reduced.

[0054] Therefore, by controlling the outer fan to run at the target rotating speed when the compressor is in frequency conversion operation, the reverse vibration generated by the outer fan when running can offset the vibration generated by the compressor, and the vibration transmitted to the shell of the integrated air conditioner can be reduced, compared with the prior art, the noise generated by the shell of the integrated air conditioner can be reduced, thereby the product quality of the integrated air conditioner can be improved, and further the user experience of the integrated air conditioner can be improved.

[0055] In some embodiments of the present application, the step of determining the target rotating speed of the outer fan according to the foot acceleration can further include the following steps:

[0056] S201, determining a position parameter between the compressor and the outer fan, and determining a radius of a wind wheel of the outer fan;

[0057] S202, determining the target rotating speed according to the position parameter, the radius of the wind wheel and the foot acceleration.

[0058] In the above formula, the radius of the wind wheel of the outer fan can be preset by a designer, and the preset radius of the wind wheel of the outer fan can be stored in a data storage unit in the all-in-one air conditioner. The position parameter of the compressor and the position parameter of the outer fan can respectively refer to an installation position of the compressor in the all-in-one air conditioner and an installation position of the outer fan in the all-in-one air conditioner, and the position parameter between the compressor and the outer fan can be determined according to the position parameter of the compressor and the position parameter of the outer fan.

[0059] Further, according to the installation position of the compressor in the all-in-one air conditioner, a distance between a fixed position of the compressor on the first structural member and an outermost foot of the compressor away from the fixed position can be determined. According to the installation position of the outer fan in the all-in-one air conditioner, a distance between a fixed position of the outer fan on the first structural member and a center of the wind wheel of the outer fan can be determined.

[0060] Therefore, the controller can determine the target rotating speed of the outer fan according to the position parameter between the compressor and the outer fan, the radius of the wind wheel of the outer fan and the foot acceleration, so that the controller can accurately adjust the vibration generated by the outer fan, effectively reduce the vibration generated by the compressor, and avoid that the vibration generated by the outer fan is too large to cause the shell to generate a large noise, thereby further improving the product quality of the all-in-one air conditioner, and further improving the user experience of the all-in-one air conditioner.

[0061] In some embodiments of the present application, for example, when the all-in-one air conditioner is an all-in-one air conditioner as shown in Figures 2-5 , that is, when the motor of the outer fan is located at the upper part of the wind wheel of the outer fan, the target rotating speed is determined according to the following formula: 2 *r*l w =l c *a c , wherein W is the target rotating speed of the outer fan, r is the radius of the wind wheel of the outer fan, a c is the foot acceleration, l w is the distance between the fixed position and the center of the wind wheel of the outer fan, and l c is the distance between the fixed position and the outermost foot of the compressor away from the fixed position.

[0062] The above formula can also be changed to: W2 = l c w * a c It should be noted that the radius of the impeller of the outer fan, the distance between the fixed position and the center of the impeller of the outer fan, and the distance between the fixed position and the outermost bottom of the compressor away from the fixed position are constants, that is, l c w is a constant, and a c is a variable. After the controller obtains the bottom acceleration of the compressor, the target speed of the outer fan can be calculated by the above formula using the control method, and the controller can control the outer fan to operate at the target speed of the outer fan, thereby reducing the vibration transmitted to the casing.

[0063] In some other embodiments of the present application, when the motor of the outer fan is located at the lower part of the impeller of the outer fan, the target speed is determined according to the following formula: W 2 * r = l c * a c / l w - a m , wherein W is the target speed, r is the radius of the impeller, a c is the bottom acceleration, l w is the distance between the fixed position and the center of the impeller of the outer fan, l c is the distance between the fixed position and the outermost bottom of the compressor away from the fixed position, and a m is the tangential acceleration of the motor of the outer fan. It should be noted that the controller can also be used to obtain the tangential acceleration of the motor of the outer fan.

[0064] When the motor of the outer fan is located at the lower part of the impeller of the outer fan, compared with the case that the motor of the outer fan is located at the upper part of the impeller of the outer fan, the influence of the moment of inertia of the motor of the outer fan on the vibration transmitted to the casing needs to be calculated additionally when the target speed of the outer fan is calculated using the control method. The above formula can also be changed to: W 2 = (l c / l w r) * a c - a m / r. Wherein (l c / l w r) and r are constants, and a c and a m are variables. After the controller obtains the bottom acceleration of the compressor and the tangential acceleration of the motor of the outer fan, the target speed of the outer fan can be calculated by the above formula using the control method, and the controller can control the outer fan to operate at the target speed of the outer fan, thereby reducing the vibration transmitted to the casing.

[0065] ​​In some embodiments of the present application, determining that the compressor is operating at a frequency that is increased can include the following steps:

[0066] S501, determine the set temperature of the integrated air conditioner, and detect the indoor environment temperature. The set temperature of the integrated air conditioner can be preset by the user, that is, the set temperature of the integrated air conditioner can be the indoor environment temperature expected by the user, and the integrated air conditioner can adjust the indoor environment temperature to the set temperature.

[0067] S502, when the integrated air conditioner is operating in a cooling mode, if the indoor environment temperature is greater than the set temperature, it is determined that the compressor is operating at an increased frequency. That is, in the cooling mode of the integrated air conditioner, the indoor environment temperature is T1, and the set temperature is T0. When the relationship T1>T0 is satisfied, it is proved that the indoor environment temperature is too high, and the integrated air conditioner needs to reduce the indoor environment temperature. The control method can control the compressor to operate at an increased frequency through the controller. The vibration generated when the compressor operates at an increased frequency increases. At this time, the control method can control the outer fan to operate at a target speed to reduce the vibration transmitted to the casing.

[0068] S503, when the integrated air conditioner is operating in a heating mode, if the indoor environment temperature is less than the set temperature, it is determined that the compressor is operating at an increased frequency. That is, in the heating mode of the integrated air conditioner, when the relationship T1

[0069] In some embodiments of the present application, when the compressor is operating at an increased frequency, the control method can further include the following steps:

[0070] S601, control the inner fan of the integrated air conditioner to operate at a set gear. According to the integrated air conditioner of the above-mentioned embodiments, the inner fan and the outer fan are arranged in the second air duct and the first air duct respectively. The inner fan and the outer fan can be arranged apart from each other, and the inner fan is not fixed in the casing through the first structure. Therefore, the vibration generated by the inner fan cannot increase or offset the vibration generated by the compressor through the first structure. By controlling the inner fan of the integrated air conditioner to operate at a set gear, the control difficulty of the control method can be reduced. Furthermore, such arrangement can reduce the influence of the inner fan on the cooling effect or heating effect of the integrated air conditioner, thereby further improving the product quality of the integrated air conditioner.

[0071] In some embodiments of the present application, when the integrated air conditioner is in cooling operation, if the indoor environment temperature is less than or equal to the set temperature, the compressor is controlled to work at a reduced frequency, and the outer fan and the inner fan of the integrated air conditioner are controlled to work at a preset lowest gear. That is, in the cooling mode of the integrated air conditioner, when the relationship T1≤T0 is satisfied, it is proved that the indoor environment temperature has reached or is lower than the indoor environment temperature expected by the user, and the integrated air conditioner does not need to further reduce the indoor environment temperature. The control method can control the compressor to work at a reduced frequency to reduce the working power of the integrated air conditioner through the controller.

[0072] The vibration generated when the compressor works at a reduced frequency is reduced, at this time, the outer fan does not need to run at the target speed to reduce the vibration of the compressor, and the control method can control the outer fan and the inner fan to work at a preset lowest gear. At the lowest gear of the outer fan and the inner fan, the outer fan and the inner fan can both generate lower vibration, and the noise generated after the vibration is transmitted to the cabinet is reduced, which can further improve the product quality of the integrated air conditioner, and further improve the user experience of the integrated air conditioner.

[0073] In some embodiments of the present application, when the integrated air conditioner is in heating operation, if the indoor environment temperature is greater than or equal to the set temperature, the compressor is controlled to work at a reduced frequency, and the outer fan and the inner fan of the integrated air conditioner are controlled to work at a preset lowest gear. That is, in the heating mode of the integrated air conditioner, when the relationship T1≥T0 is satisfied, it is proved that the indoor environment temperature has reached or is higher than the indoor environment temperature expected by the user, and the integrated air conditioner does not need to further improve the indoor environment temperature.

At the lowest gear of the outer fan and the inner fan, the outer fan and the inner fan can both generate lower vibration, and the noise generated after the vibration is transmitted to the cabinet is reduced, which can further improve the product quality of the integrated air conditioner, and further improve the user experience of the integrated air conditioner.

[0075] The control method of the integrated air conditioner is used to control the integrated air conditioner of one of the above embodiments. The maximum power of the integrated air conditioner is 2600W. The vibration transmitted to the cabinet of the integrated air conditioner without using the control method is tested, and the vibration transmitted to the cabinet of the integrated air conditioner using the control method is tested. It can be found that when the acceleration of the bottom foot of the compressor is 1.52m / s 2 , the amplitude of the top shell during the test is 35mm when the integrated air conditioner does not use the control method, and when the acceleration of the bottom foot of the compressor is 3.4m / s 2 , the amplitude of the top shell during the test is 5mm when the integrated air conditioner uses the control method. Therefore, it can be seen that the vibration of the top of the cabinet can be effectively reduced by using the control method of the application.

[0076] And on the side plate of the cabinet, when the acceleration of the bottom foot of the compressor is 6.4m / s 2 , the amplitude of the side plate during the test is 7.4mm when the integrated air conditioner does not use the control method, and when the acceleration of the bottom foot of the compressor is 1.8m / s 2 , the amplitude of the top shell during the test is 5mm when the integrated air conditioner uses the control method. Therefore, it can be seen that the vibration of the side plate of the cabinet can be effectively reduced by using the control method of the application.
