Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to an anti-dumping air conditioner and a control method thereof. Background Art

[0002] At present, household air conditioners are widely used, such as household cabinets, and are also widely used on ships. However, since ships work on the water, they are inevitably bumpy, which can cause the cabinet to tip over and other dangers. Therefore, cabinets are currently used on ships with similar fixing devices fixed on the ship. However, the fixing device requires additional costs and needs to be made by a third-party company. Not only will it be very inconvenient, but the fixing device will also occupy the ship's space or damage the ship's hull, which has certain defects. Summary of the invention

[0003] To solve the above problems, the present invention provides an anti-dumping air conditioner and a control method. A gyroscope is arranged on the base, and the axial stability of the gyroscope when running at high speed is utilized to stabilize the air conditioner on the central axis. Even if the ship tilts, the air conditioner can be ensured not to dump.

[0004] An anti-dumping air conditioner comprises a cabinet body and a base, and also comprises an anti-dumping component arranged in the base. The anti-dumping component comprises a mechanical gyroscope and a motor driving the mechanical gyroscope to operate.

[0005] When the gyroscope rotates at high speed, its axis of rotation remains stable due to inertia, and at the same time resists any force that changes the direction of its axis of rotation. The gyroscope's axis fixation during high-speed operation can be used to stabilize the air conditioner on the central axis, ensuring that the air conditioner does not fall over even if the ship tilts.

[0006] Furthermore, the lower surface of the base includes a curved surface.

[0007] When the hull tilts, the curved surface of the base contacts the hull, so that the air conditioner is stabilized on the central axis to ensure that the air conditioner does not tip over.

[0008] Furthermore, the motor is fixed on a motor fixing bracket, and the motor fixing bracket is fixed to the base or the side plate of the cabinet.

[0009] Furthermore, a center line of a rotation axis of the mechanical gyroscope coincides with a center line of the cabinet.

[0010] The air conditioner is kept in a vertical position by utilizing the axial stability of the gyroscope when it is running at high speed.

[0011] Furthermore, the upper end of the rotating shaft of the mechanical gyroscope is connected to the motor output shaft, and the lower end is connected to the base.

[0012] Furthermore, the upper end of the rotating shaft of the mechanical gyroscope passes through an upper supporting frame, and a bearing is provided between the rotating shaft and the upper supporting frame.

[0013] Furthermore, a bearing is provided between the rotating shaft of the mechanical gyroscope and the base.

[0014] The base supports the mechanical gyroscope, while the bearings allow the gyroscope to operate with less resistance.

[0015] Furthermore, the mechanical gyroscope is a vacuum gyroscope.

[0016] The vacuum gyroscope reduces the effect of air resistance when rotating at high speed, so that it can run longer without external force, thereby saving electricity and extending the service life of the motor.

[0017] Furthermore, the air conditioner also includes a retractable supporting device.

[0018] When the air conditioner is stopped, the retractable support device supports the hull to prevent the air conditioner from tipping over.

[0019] Furthermore, a clutch device is provided between the motor and the mechanical gyroscope.

[0020] Furthermore, the clutch device is an electromagnetic clutch.

[0021] Furthermore, the electromagnetic clutch includes an electromagnetic coil, a suction cup, an active disk and a passive disk, the suction cup is located between the active disk and the passive disk, the active disk is connected to the motor output shaft, and the passive disk is connected to the rotating shaft of the mechanical gyroscope.

[0022] When the mechanical gyroscope reaches a predetermined speed, the electromagnetic clutch is engaged, the motor is separated from the mechanical gyroscope, and the motor stops running, thereby achieving the purpose of energy saving.

[0023] The present invention also provides a control method for an anti-dumping air conditioner, and the specific steps are as follows:

[0024] Step S1: After the air conditioner is turned on, the anti-dumping function is turned on by remote control, buttons, etc., or the anti-dumping function is turned on by default after the air conditioner is turned on, and the anti-dumping mode is entered.

[0025] Step S2: After entering the anti-dumping mode, the air conditioning controller controls the motor to run so as to drive the mechanical gyroscope to rotate.

[0026] Step S3: When it is detected that the motor speed and / or the mechanical gyroscope speed reaches N1 rpm / min, the mechanical gyroscope is in a stable operating state.

[0027] Furthermore, the method further includes step S4: when it is detected that the motor speed and / or the mechanical gyroscope speed is less than N2 rpm / min, the air conditioner gives a mechanical gyroscope fault prompt.

[0028] The present invention also provides a control method for an anti-dumping air conditioner, and the specific steps are as follows:

[0029] Step Z1: After the air conditioner is turned on, the anti-dumping function is turned on by remote control, buttons, etc., or the anti-dumping function is turned on by default after the air conditioner is turned on, and the anti-dumping mode is entered.

[0030] Step Z2: After entering the anti-dumping mode, the air conditioning controller controls the clutch device to engage, and the motor is connected to the mechanical gyroscope.

[0031] Step Z3: The motor drives the mechanical gyroscope to run at a high speed until it reaches N1 rpm / min, and the mechanical gyroscope is in a stable operating state.

[0032] Step Z4, the clutch device is engaged, and the motor is disconnected from the mechanical gyroscope;

[0033] Step Z5, stop the motor;

[0034] Step Z6, real-time detection of the mechanical gyroscope rotation speed, when the mechanical gyroscope rotation speed is lower than N3 rpm / min, the motor is started;

[0035] Step Z7, when the real-time rotation speed of the motor is the same as the real-time rotation speed of the gyroscope, the air conditioning controller controls the clutch device to engage, and the motor is connected to the mechanical gyroscope;

[0036] Step Z8, increase the motor speed until it reaches N1 rpm / min, and the mechanical gyroscope is in a stable operating state;

[0037] Step Z9, repeating steps Z4 to Z8 until the user turns off the anti-dumping function, the control motor and the mechanical gyroscope stop running, and then disconnecting the clutch device.

[0038] Furthermore, the method further comprises step Z10, giving a motor fault prompt when the motor speed cannot be detected during the operation of the motor.

[0039] Furthermore, the method further comprises step Z11: when the mechanical gyroscope is running, the rotation speed of the mechanical gyroscope cannot be detected, and a mechanical gyroscope fault prompt is given. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0052] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understood, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0053] Example 1

[0054] See also Figure 2-4 An anti-dumping air conditioner includes a cabinet 100 and a base 200, and also includes an anti-dumping component 300 arranged in the base 200, the anti-dumping component 300 includes a mechanical gyroscope 320 and a motor 310 driving the mechanical gyroscope 320 to operate.

[0055] A motor 310 and a mechanical gyroscope 320 are added to the cabinet base. When the gyroscope rotates at high speed, its rotation axis remains stable due to inertia, and at the same time resists any force that changes the direction of its rotation axis. The fixed axis property of the gyroscope when running at high speed is used to stabilize the air conditioner on the central axis, so that the air conditioner will not fall over even if the ship tilts.

[0056] The lower surface of the base 200 includes an arc-shaped surface, such as an ellipse or a bowl shape.

[0057] When the hull is tilted, the curved surface of the base 200 contacts the hull, so that the air conditioner is stabilized on the central axis to ensure that the air conditioner does not fall over.

[0058] The motor 310 is fixed on a motor fixing bracket 312 , and the motor fixing bracket 312 is fixed to the base 200 or the side plate of the cabinet 100 .

[0059] The center line of the rotation axis 321 of the mechanical gyroscope 320 coincides with the center line of the cabinet 100 .

[0060] The upper end of the rotating shaft 321 of the mechanical gyroscope 320 is connected to the motor output shaft 311 , and the lower end is connected to the base 200 .

[0061] The upper end of the rotating shaft 321 of the mechanical gyroscope 320 passes through the upper support frame 340 , and a bearing 350 is disposed between the rotating shaft 321 and the upper support frame 340 .

[0062] The lower end of the rotating shaft 321 of the mechanical gyroscope 320 is connected to the base 200 , and a bearing 350 is provided between the rotating shaft 321 of the mechanical gyroscope 320 and the base.

[0063] The base 200 supports the mechanical gyroscope 320 , and the bearing 350 can reduce the resistance when the gyroscope operates.

[0064] The mechanical gyroscope can be a vacuum gyroscope, which reduces the effect of air resistance on it when rotating at high speed, so that it can run longer when no external force is applied, thereby achieving the purpose of saving electricity and extending the service life of the motor.

[0065] The air conditioner also includes a retractable support device (not shown in the figure). When the air conditioner is stopped, the retractable support device is supported on the hull to prevent the air conditioner from tipping over. The retractable support device can be a hydraulic support.

[0066] Example 2

[0067] See also Figure 6-7 The control method of the anti-dumping air conditioner shown in Example 1 has the following specific steps:

[0068] Step S1: After the air conditioner is turned on, the anti-dumping function is turned on by remote control, buttons, etc., or the anti-dumping function is turned on by default after the air conditioner is turned on, and the anti-dumping mode is entered.

[0069] Step S2: After entering the anti-dumping mode, the air conditioning controller controls the motor to run so as to drive the mechanical gyroscope to rotate.

[0070] Step S3: When it is detected that the motor speed and / or the mechanical gyroscope speed reaches N1 rpm / min, the mechanical gyroscope is in a stable operating state.

[0071] The rotation speed measurement device can be integrated into the motor or into the gyroscope.

[0072] The motor 310 may be a fixed speed motor, that is, after the motor is turned on, it runs at a fixed speed without speed feedback; however, a variable speed motor may be used to detect the motor speed in real time to confirm whether the gyroscope has reached a stable operating state.

[0073] The control method also includes failure detection and fault reminder.

[0074] Step S4: When it is detected that the motor speed and / or the mechanical gyroscope speed is less than N2 rpm / min, the mechanical gyroscope 320 cannot maintain its axis stability, and the air conditioner has a risk of tipping over. The air conditioner gives a mechanical gyroscope failure prompt to remind the user to report a repair.

[0075] Example 3

[0076] See also Figure 4-5 The anti-dumping assembly in this embodiment is added with a clutch device, and the rest of the structure is the same as that of embodiment 1.

[0077] A clutch device is provided between the motor 310 and the mechanical gyroscope 320. When the mechanical gyroscope reaches a predetermined speed, the motor 310 and the mechanical gyroscope 320 are separated and the motor stops running, thereby achieving the purpose of energy saving.

[0078] The clutch device is an electromagnetic clutch 330 .

[0079] The electromagnetic clutch 330 includes an electromagnetic coil 331 , a suction cup 332 , an active disk 333 and a passive disk 334 . The suction cup 332 is located between the active disk 333 and the passive disk 334 . The active disk 333 is connected to the motor output shaft 311 , and the passive disk 334 is connected to the rotating shaft 321 of the mechanical gyroscope 320 .

[0080] Example 4

[0081] See also Figure 8-9 The control method of the anti-dumping air conditioner shown in Example 3 has the following specific steps:

[0082] Step Z1: After the air conditioner is turned on, the anti-dumping function is turned on by remote control, buttons, etc., or the anti-dumping function is turned on by default after the air conditioner is turned on, and the anti-dumping mode is entered.

[0083] Step Z2: After entering the anti-dumping mode, the air conditioning controller controls the clutch device to engage, and the motor is connected to the mechanical gyroscope.

[0084] Step Z3: The motor drives the mechanical gyroscope to run at a high speed until it reaches N1 rpm / min, and the mechanical gyroscope is in a stable operating state.

[0085] Step Z4, the clutch device is engaged, and the motor is disconnected from the mechanical gyroscope;

[0086] Step Z5, stop the motor;

[0087] Step Z6, real-time detection of the mechanical gyroscope rotation speed, when the mechanical gyroscope rotation speed is lower than N3 rpm / min, the motor is started;

[0088] Step Z7, when the real-time rotation speed of the motor is the same as the real-time rotation speed of the gyroscope, the air conditioning controller controls the clutch device to engage, and the motor is connected to the mechanical gyroscope;

[0089] Step Z8, increase the motor speed until it reaches N1 rpm / min, and the mechanical gyroscope is in a stable operating state;

[0090] Step Z9, repeating steps Z4 to Z8 until the user turns off the anti-dumping function, the control motor and the mechanical gyroscope stop running, and then disconnecting the clutch device.

[0091] Step Z10: when the motor is running and the motor speed cannot be detected, a motor fault prompt is given to remind the user to report a repair;

[0092] Step Z11: when the mechanical gyroscope is running, the rotation speed of the mechanical gyroscope cannot be detected, and a mechanical gyroscope fault prompt is given to remind the user to report a repair.

[0093] In step Z7, the motor is first accelerated to the same speed as the mechanical gyroscope and then connected to the mechanical gyroscope. The purpose is that if the mechanical gyroscope runs at high speed and the motor does not run, the mechanical gyroscope directly attracts the motor, which will cause a certain impact on the motor, or cause the motor to rotate passively, and the reverse current generated by the motor will cause an impact on the air-conditioning controller, thereby causing damage to the controller.
