[0002] The biggest feature of a mobile air conditioner is that it can be moved arbitrarily, and its usage scenarios involve living rooms, bedrooms, bathrooms, kitchens, basements, etc. During use, users often change its placement position. If the mobile air conditioner is placed at a certain angle with the horizontal plane during operation or the whole machine topples 90° due to collision, the condensed water in the water tank will randomly deflect to one side, which is extremely likely to cause the condensed water to overflow to the outside of the mobile air conditioner body. Moreover, after the compressor has a large tilt angle, its internal parts will be damaged, causing losses to users.

[0003] In the related art, a mobile air conditioner is provided with an information detection device. The inclination angles of the four directions of the mobile air conditioner are detected by sensors in the information detection device to determine the inclination state of the mobile air conditioner, and different alarm messages are sent according to different inclination states. However, the above method requires an additional device to be installed inside the mobile air conditioner body to detect the inclination angle generated by the mobile air conditioner body in real time, which increases the cost and occupies the internal space of the mobile air conditioner.

[0032] The embodiments of the present invention will be described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention will be described in detail below.

[0033] The following will be combined with Figures 1-6 To illustrate the mobile air conditioner 10 of the embodiment of the present invention by way of example.

[0034] As Figure 1 shown, the mobile air conditioner 10 of the embodiment of the present invention includes: a refrigerant circuit 1, a water tank 2, a first weight sensor 3, a second weight sensor 4, a water spraying motor 5, and a controller 6. Among them,

[0035] In the refrigerant circuit 1, the refrigerant circulates successively through a compressor, a condenser, a pressure reducer, and an evaporator. One of the condenser and the evaporator is an outdoor heat exchanger, and the other is an indoor heat exchanger; the water tank 2 is used to hold the condensed water generated during the operation of the evaporator, including a first half tank and a second half tank, and the first half tank and the second half tank are symmetrically arranged according to the center line; the first weight sensor 3 is arranged at the center position on the back of the first half tank and is used to detect the weight of the condensed water in the first half tank; the second weight sensor 4 is arranged at the center position on the back of the second half tank and is used to detect the weight of the condensed water in the second half tank; the water spraying motor 5 is used to spray the condensed water in the water tank 2 onto the condenser; the controller 6 is configured to: obtain the first weight of the condensed water in the first half tank and the second weight of the condensed water in the second half tank; when the first weight is equal to the second weight and the total weight detected by the first weight and the second weight does not exceed a preset total weight, it is determined that the water tank 2 is in a waterless state, and in the waterless state, the waterless tilt angle of the mobile air conditioner 10 is determined according to the first weight and the second weight. When the waterless tilt angle is the first preset waterless tilt angle, the compressor is controlled to stop; when the total weight detected by the first weight and the second weight exceeds the preset total weight, and / or the first weight is not equal to the second weight, it is determined that the water tank 2 is in a water state, and in the water state, the water tilt angle of the mobile air conditioner 10 is determined according to the first weight and the second weight. When the water tilt angle is greater than the preset water tilt angle, the compressor of the mobile air conditioner 10 is controlled to stop and / or the mobile air conditioner 10 is controlled to power off.

[0036] In an embodiment, after the mobile air conditioner 10 is powered on, product parameters are first read from the EEPROM (Electrically Erasable Programmable Read Only Memory). The parameters include the horizontal weight when the water tank 2 located on the lower side of the body of the mobile air conditioner 10, i.e., the first half-tank and the second half-tank symmetrically arranged, is without water, namely the first preset weight, for example, denoted as TankLeft, and the second preset weight, for example, denoted as TankRight.

[0037] After the mobile air conditioner 10 is started and running, if the mobile air conditioner 10 operates in the cooling mode or the dehumidifying mode, the compressor of the refrigerant circuit 1 discharges the refrigerant to the condenser; the water tank 2 located on the lower side of the body of the mobile air conditioner 10, i.e., the first half-tank and the second half-tank symmetrically arranged, generates condensed water. A first weight sensor 3 is arranged at the center position on the back of the first half-tank for real-time detection of the weight of the condensed water in the first half-tank; a second weight sensor 4 is arranged at the center position on the back of the second half-tank for real-time detection of the weight of the condensed water in the second half-tank; the water spraying motor 5 is turned on to spray the condensed water in the first half-tank and the second half-tank onto the condenser.

[0038] After the water spraying motor 5 is turned on, the controller 6 obtains the first weight of the condensed water in the first half-tank, for example, denoted as TankLeftR, and the second weight of the condensed water in the second half-tank, for example, denoted as TankRightR. The first weight TankLeftR and the second weight TankRightR change in real time, and the controller 6 judges the magnitude relationship between the first weight TankLeftR and the second weight TankRightR, and the magnitude relationship between the total detected weight of the first weight TankLeftR and the second weight TankRightR and the preset total weight. If the first weight TankLeftR is equal to the second weight TankRightR, it is considered that the water spraying motor 5 has sprayed the condensed water in the water tank 2 clean. It is possible that the mobile air conditioner 10 tilts when there is no condensed water, and when the total detected weight of the first weight TankLeftR and the second weight TankRightR does not exceed the preset total weight, it is possible that the mobile air conditioner 10 is horizontally placed when there is no condensed water. Then, it is determined that the water tank 2 is in a waterless state. In the waterless state, according to the magnitude relationship between the first weight TankLeftR and the second weight TankRightR and the first preset weight TankLeft and the second preset weight TankRight, different waterless tilt angles of the mobile air conditioner 10 when there is no condensed water are determined. Among them, when the waterless tilt angle reaches the first preset waterless tilt angle, for example, 90°, it is considered that the mobile air conditioner 10 topples, which may cause danger. Then, the compressor is controlled to stop to prevent damage to the compressor and affect the subsequent use of the mobile air conditioner 10.

[0039] When the total detected weight of the first weight TankLeftR and the second weight TankRightR exceeds the preset total weight, it is possible that the mobile air conditioner 10 is placed horizontally when there is condensate; and / or the first weight TankLeftR is not equal to the second weight TankRightR. It is considered that even if the water spraying motor 5 sprays the condensate, the evaporation rate of the condensate may not be as fast as the condensation rate of the evaporator. There is still condensate in the first half-tank and the second half-tank and the weights are different, that is, there is more condensate accumulated in the water tank 2. If too much condensate accumulates, it will overflow the body of the mobile air conditioner 10, and it is possible that the mobile air conditioner 10 is tilted when there is condensate. Then it is determined that the water tank 2 is in a water state. In the water state, according to the magnitude relationship between the first weight TankLeftR and the second weight TankRightR and the first preset weight TankLeft and the second preset weight TankRight, different water-inclination angles of the mobile air conditioner 10 when there is condensate are determined. Among them, when the water-inclination angle is greater than the preset water-inclination angle, it is considered that the mobile air conditioner 10 is tilted when there is condensate, which may be dangerous. Then the compressor of the mobile air conditioner 10 is controlled to stop, to prevent damage to the compressor and affect the subsequent use of the mobile air conditioner 10, and / or the mobile air conditioner 10 is controlled to cut off the power, to avoid condensate entering the circuit board of the mobile air conditioner 10 and causing a short circuit.

[0040] For the mobile air conditioner 10 according to an embodiment of the present invention, after obtaining the first weight of the condensate in the first half-tank and the second weight of the condensate in the second half-tank, it is judged whether there is condensate in the water tank 2 according to the relationship between the first weight and the second weight and the preset total weight, to determine the non-water-inclination angle or the water-inclination angle corresponding to the mobile air conditioner 10. When the non-water-inclination angle reaches the preset non-water-inclination angle, the compressor is controlled to stop, or when the water-inclination angle reaches the preset water-inclination angle, the compressor of the mobile air conditioner 10 is controlled to stop and / or the mobile air conditioner 10 is controlled to cut off the power. By judging whether the mobile air conditioner 10 is tilted and its inclination angle according to the change in the self-weights of the first half-tank and the second half-tank at the bottom of the mobile air conditioner 10, and formulating corresponding control methods for the relevant components of the mobile air conditioner 10 when the non-water-inclination angle and the water-inclination angle reach the corresponding preset inclination angles, it is possible to avoid the condensate in the water tank 2 from overflowing and the relevant components from being damaged without increasing additional costs and reducing the occupied space of the mobile air conditioner 10, and ensure the use safety of users.

[0041] In some embodiments, the mobile air conditioner 10 further includes an alarm device. The non-water-inclination angle is the first preset non-water-inclination angle. When controlling the compressor to stop, the controller 6 is further configured to: control the mobile air conditioner 10 to enter the standby state and control the alarm device to send a prompt message.

[0042] In an embodiment, in a waterless state, when the waterless tilt angle is the first preset waterless tilt angle, i.e., 90°, the controller 6 controls the compressor to stop operating, and also controls the mobile air conditioner 10 to enter the standby state. At the same time, the controller controls the alarm device to send a prompt message at preset time intervals, and displays the prompt message, such as "BE", on the display panel of the mobile air conditioner 10, effectively reducing the safety risk and improving the user experience.

[0043] In some embodiments, the mobile air conditioner 10 further includes a blower, and the blower includes an upper blower and a lower blower. In a waterless state, the controller 6 is further configured to: when the waterless tilt angle is greater than the second preset waterless tilt angle, control the compressor to operate at a first operating frequency and control the upper blower and the lower blower to operate at a first rotational speed, and display a prompt message on the display panel of the mobile air conditioner 10, where the first operating frequency is greater than or equal to the minimum operating frequency of the compressor and less than the maximum operating frequency of the compressor, the first rotational speed is greater than or equal to the minimum rotational speed of the blower and less than the maximum rotational speed of the blower, and the second preset waterless tilt angle is less than the first preset waterless tilt angle.

[0044] In an embodiment, as Figure 2 shown, it is a flowchart of the control method corresponding to the waterless tilt angle of the mobile air conditioner according to the embodiment of the present invention. In a waterless state, when the waterless tilt angle is greater than the second preset waterless tilt angle, such as 45°, the controller 6 controls the compressor of the mobile air conditioner 10 to operate at a first operating frequency, avoiding the increase of internal vibration of the compressor due to the too large tilt angle and damaging the pipeline; and controls the upper blower and the lower blower to operate at a first rotational speed to reduce the vibration of the whole machine, and displays a prompt message, such as "BE", on the display panel of the mobile air conditioner 10, effectively reducing the safety risk and improving the user experience, where the second preset waterless tilt angle of 45° is less than the first preset waterless tilt angle of 90°.

[0045] In some embodiments, in a waterless state, the controller 6 is further configured to: when the waterless tilt angle is less than the second preset waterless tilt angle, control the compressor to operate at a second operating frequency, where the second operating frequency is half of the target operating frequency of the compressor.

[0046] In an embodiment, as Figure 2 shown, in a waterless state, when the waterless tilt angle is less than the second preset waterless tilt angle, i.e., 45°, the controller 6 controls the compressor to operate at a second operating frequency, i.e., half of the target operating frequency. By reducing the operating frequency of the compressor, the internal vibration of the compressor is reduced, and at the same time, other loads operate according to the preset state, effectively reducing the safety risk and improving the user experience.

[0047] In some embodiments, in a waterless state, the controller 6 is further configured to: when the waterless tilt angle is the third preset waterless tilt angle, control the compressor and the blower of the mobile air conditioner 10 to maintain the current operating state.

[0048] In an embodiment, as Figure 2 shown, in a waterless state, when the waterless tilt angle is the third preset waterless tilt angle, such as 0°, it is considered that the current water tank 2 is in a horizontal state and no special treatment is required, and then the load of the mobile air conditioner 10, that is, the compressor and the blower, is controlled to maintain the current operating state.

[0049] In some embodiments, the preset total weight is the sum of the first preset weight and the second preset weight. When determining the waterless tilt angle of the mobile air conditioner 10 according to the first weight and the second weight, the controller 6 is configured to: when both the first weight and the second weight are equal to the third preset weight, determine that the waterless tilt angle is the first preset waterless tilt angle; when the first weight is not equal to the product of the first preset weight and the preset cosine angle and the product exceeds the first weight, determine that the waterless tilt angle is greater than the second preset waterless tilt angle; when the first weight is not equal to the product of the first preset weight and the preset cosine angle and the product does not exceed the first weight, determine that the waterless tilt angle is less than the second preset waterless tilt angle; when the first weight is equal to the first preset weight, determine that the waterless tilt angle is the third preset waterless tilt angle, where the first preset waterless tilt angle is greater than the second preset waterless tilt angle, and the second preset waterless tilt angle is greater than the third preset waterless tilt angle.

[0050] In an embodiment, as Figure 3 shown, it is a flowchart for determining the waterless tilt angle of the mobile air conditioner according to an embodiment of the present invention. After obtaining the first weight TankLeftR of the condensed water in the first half tank and the second weight TankRightR of the condensed water in the second half tank, if both the first weight TankLeftR and the second weight TankRightR are equal to the third preset weight TankLeft, for example, 0, that is, when TankLeftR = TankRightR = 0, it is considered that the first weight sensor 3 and the second weight sensor 4 are perpendicular to the ground at the same time as the bottom of the water tank 2, and there is no weight above the first weight sensor 3 and the second weight sensor 4, then the waterless tilt angle is determined to be the first preset waterless tilt angle, that is, 90°. It can be understood that when the body of the mobile air conditioner 10 is tilted without water, the tilt angle gradually increases until it reaches the first preset waterless tilt angle of 90°, rather than instantly tilting to the first preset waterless tilt angle of 90°.

[0051] If the first weight TankLeftR is equal to the product of the first preset weight TankLeft and the preset cosine angle, such as cos45°, that is, when TankLeftR = TankLeft * cos45°, it is considered that the first weight TankLeftR detected by the first weight sensor 3 is equal to the weight of the vertical inclined plane when there is no water preset, and the anhydrous tilt angle is determined to be the second preset anhydrous tilt angle, that is, 45°.

[0052] If the first weight TankLeftR is not equal to the product of the first preset weight TankLeft and the preset cosine angle cos45°, that is, when TankLeftR ≠ TankLeft * cos45°, it is considered that the first weight TankLeftR detected by the first weight sensor 3 is not equal to the weight of the vertical inclined plane when there is no water preset, and it is possible that the product exceeds the first weight TankLeftR, that is, TankLeftR < TankLeft * cos45°. It is considered that the first weight TankLeftR detected by the first weight sensor 3 is less than the weight of the vertical inclined plane when there is no water preset, and the anhydrous tilt angle is determined to be greater than the second preset anhydrous tilt angle of 45°.

[0053] It is also possible that the product does not exceed the first weight TankLeftR, that is, TankLeftR ≥ TankLeft * cos45°. It is considered that the first weight TankLeftR detected by the first weight sensor 3 is greater than the weight of the vertical inclined plane when there is no water preset, and the anhydrous tilt angle is determined to be less than the second preset anhydrous tilt angle of 45°.

[0054] If the first weight TankLeftR is equal to the first preset weight TankLeft, that is, when TankLeftR = TankLeft, it is considered that the first weight TankLeftR detected by the first weight sensor 3 is equal to the horizontal weight when there is no water in the first half tank, and the anhydrous tilt angle is determined to be the third preset anhydrous tilt angle, that is, 0°. Among them, the first preset anhydrous tilt angle of 90° is greater than the second preset anhydrous tilt angle of 45°, and the second preset anhydrous tilt angle of 45° is greater than the third preset anhydrous tilt angle of 0°.

[0055] In some embodiments, the preset water-inclination angles include a first preset water-inclination angle and a second preset water-inclination angle. When the water-inclination angle is greater than the preset water-inclination angle, when controlling the compressor of the mobile air conditioner 10 to stop and / or controlling the mobile air conditioner 10 to cut off the power, the controller 6 is configured to: when the water-inclination angle is equal to the first preset water-inclination angle, control the compressor of the mobile air conditioner 10 to stop and control the mobile air conditioner 10 to cut off the power; when the water-inclination angle is greater than or equal to the second preset water-inclination angle and less than the first preset water-inclination angle, control the compressor of the mobile air conditioner 10 to stop, wherein the first preset water-inclination angle is greater than the second preset water-inclination angle.

[0056] In an embodiment, as Figure 4 shown, it is a flowchart of a control method corresponding to the water-inclination angle of the mobile air conditioner according to an embodiment of the present invention. In a water state, when the water-inclination angle is equal to the first preset water-inclination angle, i.e., 90°, the controller 6 controls the compressor of the mobile air conditioner 10 to stop, avoiding the internal part of the compressor falling off the spring or the vibration becoming larger due to the inclination, the deformation of the system copper pipeline, and the subsequent inability to be used normally; and controls the indoor unit of the mobile air conditioner 10 to disconnect the power supply of the outdoor board, avoiding the condensate water entering the circuit board and causing circuit damage, effectively reducing the safety risk and improving the user experience.

[0057] When the water-inclination angle is greater than or equal to the second preset water-inclination angle of 45° and less than the first preset water-inclination angle of 90°, the controller 6 controls the compressor of the mobile air conditioner 10 to stop, avoiding the internal part of the compressor falling off the spring or the vibration becoming larger due to the inclination, the deformation of the system copper pipeline, and the subsequent inability to be used normally.

[0058] In some embodiments, the mobile air conditioner 10 further includes an alarm device, and the blower includes a lower blower. After controlling the compressor of the mobile air conditioner 10 to stop, the controller 6 is further configured to: control the water pump motor 5 to operate at a second speed, control the lower blower to operate at a third speed, and control the alarm device to emit a prompt message, and when the cumulative duration of the prompt message reaches a first preset time, control the mobile air conditioner 10 to enter the standby state, wherein the second speed is greater than the lowest speed of the water pump motor 5 and less than or equal to the highest speed of the water pump motor 5, and the third speed is greater than the lowest speed of the lower blower and less than or equal to the highest speed of the lower blower.

[0059] In an embodiment, as Figure 4As shown, after the controller 6 controls the compressor of the mobile air conditioner 10 to stop, it controls the water pump motor 5 to operate at the second speed to accelerate the evaporation rate of the condensed water, prevent the condensed water in the water tank 2 from overflowing, and controls the lower fan to operate at the third speed. At the same time, it controls the alarm device to send a prompt message every preset time, and displays a prompt message such as "BE" on the display panel of the mobile air conditioner 10. When the cumulative duration of the prompt message reaches the first preset time, for example, 1 minute, it controls the mobile air conditioner 10 to enter the standby state, effectively reducing the safety risk and improving the user experience.

[0060] In some embodiments, the fan includes an upper fan and a lower fan. In the water presence state, the controller 6 is further configured to: when the water tilt angle is less than the second preset water tilt angle, control the compressor to operate at the third operating frequency and the upper fan and the lower fan to operate at the fourth speed, control the display panel of the mobile air conditioner 10 to display a prompt message, and when the cumulative duration of the displayed prompt message reaches the second preset time, control the compressor, the upper fan and the lower fan of the mobile air conditioner 10 to operate normally, where the third operating frequency is greater than or equal to the minimum operating frequency of the compressor and less than the maximum operating frequency of the compressor, and the fourth speed is greater than or equal to the minimum speed of the fan and less than the maximum speed of the fan.

[0061] In an embodiment, as Figure 4 shown, in the water presence state, when the water tilt angle is less than the second preset water tilt angle, i.e., 45°, the controller 6 controls the compressor to operate at the third operating frequency to reduce the generation rate of condensed water, and the upper fan to operate at the fourth speed to reduce the generation rate of condensed water, and the lower fan to operate at the fourth speed to increase the condenser temperature and accelerate the evaporation of condensed water, and controls the display panel of the mobile air conditioner 10 to display a prompt message. When the cumulative duration of the displayed prompt message reaches the second preset time, for example, 1 minute, the timing is cleared, and then the compressor, the upper fan and the lower fan of the mobile air conditioner 10 are controlled to operate normally, effectively reducing the safety risk and improving the user experience.

[0062] In some embodiments, in the water presence state, the controller 6 is further configured to: when the water tilt angle is the third preset water tilt angle, control the compressor and the fan of the mobile air conditioner 10 to maintain the current operating state.

[0063] In an embodiment, as Figure 4 shown, in the water presence state, when the water tilt angle is the third preset water tilt angle, for example, 0°, it is considered that the current water tank 2 is in a horizontal state and no special treatment is required, so the load of the mobile air conditioner 10, i.e., the compressor and the fan, is controlled to maintain the current operating state.

[0064] In some embodiments, the preset total weight is the sum of a first preset weight and a second preset weight. When determining the water-tilt angle of the mobile air conditioner 10 based on the first weight and the second weight, the controller 6 is configured to: when both the first weight and the second weight are equal to a fourth preset weight, determine that the water-tilt angle is a first preset water-tilt angle; when the first weight does not exceed the second weight and the first weight does not exceed the product of the first preset weight and the preset cosine angle, determine that the water-tilt angle is greater than a second preset water-tilt angle; when the first weight exceeds the second weight and the second weight exceeds the product of the second preset weight and the preset cosine angle, determine that the water-tilt angle is less than the second preset water-tilt angle; when the first weight and the second weight are equal, determine that the water-tilt angle is a third preset water-tilt angle, where the first preset water-tilt angle is greater than the second preset water-tilt angle, and the second preset water-tilt angle is greater than the third preset water-tilt angle.

[0065] In an embodiment, as Figure 5 shown, it is a flowchart of determining the water-tilt angle of the mobile air conditioner according to an embodiment of the present invention. After obtaining the first weight TankLeftR of the condensed water in the first half tank and the second weight TankRightR of the condensed water in the second half tank, if both the first weight TankLeftR and the second weight TankRightR are equal to the fourth preset weight TankRight, for example, 0, that is, when TankLeftR = TankRightR = 0, it is considered that the first weight sensor 3 and the second weight sensor 4 are both perpendicular to the ground at the bottom of the water tank 2, and there is no weight above the first weight sensor 3 and the second weight sensor 4, then determine that the water-tilt angle is the first preset water-tilt angle, that is, 90°. It can be understood that during the water-tipping process of the body of the mobile air conditioner 10, the tilt angle gradually increases until it reaches the first preset water-tilt angle of 90°, rather than instantly tipping to the first preset water-tilt angle of 90°.

[0066] If the first weight TankLeftR does not exceed the second weight TankRightR, and the first weight TankLeftR does not exceed the product of the first preset weight TankLeft and the preset cosine angle cos45°, that is, TankLeftR < TankRightR, and TankLeftR < TankLeft * cos45°, it is considered that the mobile air conditioner 10 tilts to the right, and the condensed water all converges in the second half tank, and there is no condensed water in the first half tank. The first weight TankLeftR detected by the first weight sensor 3 arranged at the center position on the back of the first half tank is less than the weight of the vertical inclined plane when there is no water. By the above method, the interference of the condensed water weight on the detection is avoided. In the case where there is no condensed water in the first half tank, it is more accurate to determine that the water-tilt angle of the mobile air conditioner 10 in the second half tank is greater than the second preset water-tilt angle of 45°.

[0067] If the first weight TankLeftR exceeds the second weight TankRightR, and the second weight TankRightR exceeds the product of the second preset weight TankRight and the preset cosine angle cos45°, that is, TankLeftR ≥ TankRightR, and TankRightR ≥ TankRight * cos45°, it is considered that the mobile air conditioner 10 tilts to the left, and all the condensed water converges in the first half trough, and there is no condensed water in the second half trough. The second weight TankRightR detected by the second weight sensor 4 set at the center position on the back of the second half trough is greater than or equal to the weight of the vertical inclined plane when there is no water preset. By the above method, the interference of the condensed water weight on the detection is avoided. In the case where there is no condensed water in the second half trough, it is more accurate to determine that the water-filled tilt angle of the mobile air conditioner 10 in the first half trough is less than the second preset water-filled tilt angle of 45°.

[0068] If the first weight TankLeftR is equal to the second weight TankRightR, that is, when TankLeftR = TankRightR ≠ 0, it is considered that the condensed water weights in the first half trough and the second half trough are equal, and then the water-filled tilt angle is determined to be the third preset water-filled tilt angle, that is, 0°. Among them, the first preset water-filled tilt angle of 90° is greater than the second preset water-filled tilt angle of 45°, and the second preset water-filled tilt angle of 45° is greater than the third preset water-filled tilt angle of 0°.

[0069] The following refers to Figure 6 An example is given to illustrate the tilt angle detection method of the mobile air conditioner according to the embodiment of the present invention.

[0098] For the mobile air conditioner 10 according to the embodiment of the present invention, after obtaining the first weight of the condensed water in the first half trough and the second weight of the condensed water in the second half trough, it is determined whether there is condensed water in the water tank 2 according to the relationship between the first weight and the second weight and the preset total weight, so as to determine the water absence tilt angle or the water presence tilt angle corresponding to the mobile air conditioner 10, and when the water absence tilt angle reaches the preset water absence tilt angle, control the compressor to stop, or when the water presence tilt angle reaches the preset water presence tilt angle, control the compressor of the mobile air conditioner 10 to stop and / or control the mobile air conditioner 10 to cut off the power. By judging whether the mobile air conditioner 10 is tilted and its tilt angle according to the change of the self-weights of the first half trough and the second half trough at the bottom of the mobile air conditioner 10, and formulating corresponding control methods for the relevant components of the mobile air conditioner 10 when the water absence tilt angle and the water presence tilt angle reach the corresponding preset tilt angles, it is possible to avoid the overflow of the condensed water in the water tank 2 and the damage of the relevant components while not increasing the additional cost and reducing the occupied space of the mobile air conditioner 10, ensuring the use safety of the user.

[0099] As Figure 7 shown, the tilt angle detection method of the mobile air conditioner according to the embodiment of the present invention includes at least Step S1 - Step S3.

[0100] Step S1, obtain the first weight of the condensed water in the first half trough and the second weight of the condensed water in the second half trough.

[0101] In an embodiment, after the mobile air conditioner is powered on, product parameters are first read from the EEPROM. The parameters include the horizontal weight when the water tank located on the lower side of the mobile air conditioner body, that is, the first half tank and the second half tank symmetrically arranged, is without water, namely the first preset weight, for example, denoted as TankLeft, and the second preset weight, for example, denoted as TankRight.

[0102] After the mobile air conditioner is started and running, if the mobile air conditioner operates in the cooling mode or the dehumidifying mode, the compressor in the refrigerant circuit discharges the refrigerant to the condenser; the water tank located on the lower side of the mobile air conditioner body, that is, the first half tank and the second half tank symmetrically arranged, generates condensed water. A first weight sensor is arranged at the center position on the back of the first half tank to detect the weight of the condensed water in the first half tank in real time; a second weight sensor is arranged at the center position on the back of the second half tank to detect the weight of the condensed water in the second half tank in real time; the water spraying motor is turned on to spray the condensed water in the first half tank and the second half tank onto the condenser. After the water spraying motor is turned on, the controller obtains the first weight of the condensed water in the first half tank, for example, denoted as TankLeftR, and the second weight of the condensed water in the second half tank, for example, denoted as TankRightR. The first weight TankLeftR and the second weight TankRightR change in real time.

[0103] Step S2, when the first weight is equal to the second weight and the total detected weight of the first weight and the second weight does not exceed the preset total weight, it is determined that the water tank is in a waterless state. And in the waterless state, the waterless tilt angle of the mobile air conditioner is determined according to the first weight and the second weight. When the waterless tilt angle is the first preset waterless tilt angle, the compressor is controlled to stop.

[0104] In an embodiment, the magnitude relationship between the first weight TankLeftR and the second weight TankRightR, and the magnitude relationship between the total detected weight of the first weight TankLeftR and the second weight TankRightR and the preset total weight are determined. If the first weight TankLeftR is equal to the second weight TankRightR, it is considered that the water injection motor 5 has sprayed the condensed water in the water tank 2 clean. It is possible that the mobile air conditioner 10 tilts when there is no condensed water, and when the total detected weight of the first weight TankLeftR and the second weight TankRightR does not exceed the preset total weight, it is possible that the mobile air conditioner 10 is horizontally placed when there is no condensed water. Then, it is determined that the water tank is in a waterless state. In the waterless state, different waterless tilt angles of the mobile air conditioner 10 when there is no condensed water are determined according to the magnitude relationship between the first weight TankLeftR and the second weight TankRightR and the first preset weight TankLeft and the second preset weight TankRight. Among them, when the waterless tilt angle reaches the first preset waterless tilt angle, such as 90°, it is considered that the mobile air conditioner 10 has toppled over, which may be dangerous. Then, the compressor is controlled to stop operating to prevent damage to the compressor and affect the subsequent use of the mobile air conditioner 10.

[0105] Step S3, when the total detected weight of the first weight and the second weight exceeds the preset total weight, and / or when the first weight is not equal to the second weight, it is determined that the water tank is in a water state. In the water state, the water tilt angle of the mobile air conditioner is determined according to the first weight and the second weight. When the water tilt angle is greater than the preset water tilt angle, the compressor of the mobile air conditioner is controlled to stop operating and / or the mobile air conditioner is controlled to cut off the power.

[0106] In an embodiment, when the total detected weight of the first weight TankLeftR and the second weight TankRightR exceeds the preset total weight, it is possible that the mobile air conditioner 10 is horizontally placed when there is condensate; and / or the first weight TankLeftR is not equal to the second weight TankRightR. It is considered that even if the water spraying motor 5 sprays the condensate, the evaporation rate of the condensate may not be as fast as the condensation rate of the evaporator. There is still condensate in the first half-tank and the second half-tank and the weights are different, that is, there is more condensate gathered in the water tank 2. If too much condensate gathers and overflows the body of the mobile air conditioner 10, it is possible that the mobile air conditioner 10 is tilted when there is condensate. Then it is determined that the water tank is in a water state. In the water state, according to the magnitude relationship between the first weight TankLeftR and the second weight TankRightR and the first preset weight TankLeft and the second preset weight TankRight, different water-inclination angles of the mobile air conditioner 10 when there is condensate are determined. Among them, when the water-inclination angle is greater than the preset water-inclination angle, it is considered that the mobile air conditioner 10 is tilted when there is condensate, which may be dangerous. Then the compressor of the mobile air conditioner 10 is controlled to stop, preventing damage to the compressor and affecting the subsequent use of the mobile air conditioner 10, and / or the mobile air conditioner 10 is controlled to cut off the power, avoiding condensate entering the circuit board of the mobile air conditioner 10 and causing a short circuit.

[0107] According to the tilt angle detection method of the mobile air conditioner according to the embodiment of the present invention, after obtaining the first weight of the condensate in the first half-tank and the second weight of the condensate in the second half-tank, it is judged whether there is condensate in the water tank according to the relationship between the first weight and the second weight and the preset total weight, so as to determine the non-water tilt angle or the water-inclination angle corresponding to the mobile air conditioner. When the non-water tilt angle reaches the preset non-water tilt angle, the compressor is controlled to stop, or when the water-inclination angle reaches the preset water-inclination angle, the compressor of the mobile air conditioner is controlled to stop and / or the mobile air conditioner is controlled to cut off the power. By judging whether the mobile air conditioner is tilted and its tilt angle according to the change of the self-weights of the first half-tank and the second half-tank at the bottom of the mobile air conditioner, and formulating corresponding control methods for the relevant devices of the mobile air conditioner when the non-water tilt angle and the water-inclination angle reach the corresponding preset tilt angles, it is possible to avoid the overflow of the condensate in the water tank and the damage of the relevant devices while not increasing the additional cost and reducing the occupied space of the mobile air conditioner, ensuring the use safety of the user.
