[0002] Turntable air conditioners are mainly used on rapidly rotating turntables. During use, the centrifugal force generated by the rapid rotation causes the condensed water in the water tray to tilt, making its liquid level higher than that in a stationary state.

[0003] Due to the above factors, the condensed water level in the water tray in the rotating state can easily exceed the height of the water tray, so that the condensed water will overflow and drip under the air conditioner, greatly reducing the user experience of the air conditioner. If the air conditioner is used in a cabinet or equipment room, and there are precision instruments placed under the air conditioner, the instruments will be damaged by water ingress, resulting in economic losses. Summary of the invention

[0021] See also Figure 1 to Figure 2As shown, according to an embodiment of the present application, the water receiving tray assembly includes a water receiving tray body 1 and a driving mechanism, the water receiving tray body 1 includes a water receiving port 2 opening upward, the driving mechanism is connected to the outer wall of the water receiving tray body 1, and can drive the water receiving tray body 1 to rotate at a preset angle so that the inlet plane of the water receiving port 2 is inclined at a certain angle.

[0022] During the operation of the water receiving pan assembly, when the turntable air conditioner rotates, the inclination angle of the water receiving pan body 1 can be adjusted according to the rotation direction and rotation speed of the turntable air conditioner, so that the water receiving pan body 1 at the highest point of the liquid level is tilted upward, and the height of the water receiving pan body 1 at the highest point of the liquid level is increased when the water receiving pan body 1 rotates in the horizontal direction, thereby ensuring that the high point of the liquid level does not exceed the height of the water receiving pan body 1, avoiding the problem of condensed water overflow, and improving the working reliability of the water receiving pan assembly.

[0023] In one embodiment, the driving mechanism includes a driving motor 3 and a connecting member, one end of the connecting member is connected to the output shaft of the driving motor 3, and the other end of the connecting member is fixedly connected to the outer wall of the water receiving tray body 1, and the water receiving tray body 1 can rotate around the output shaft.

[0024] In this embodiment, the driving motor 3 is directly connected to the water receiving tray body 1 through a connecting piece, and the output shaft of the driving motor 3 is coaxial with the rotation axis of the water receiving tray body 1, so that the horizontal inclination angle of the water receiving tray body 1 can be conveniently adjusted by the driving motor 3.

[0025] In order to ensure the force balance of the water receiving tray body 1 during the rotation process, in this embodiment, the driving motor 3 is connected to the center position of the connecting side surface of the water receiving tray body 1 through a connecting piece.

[0026] In an embodiment not shown in the figures, the driving motor 3 may also be connected to the water receiving tray body 1 through a transmission mechanism, so that the inclination angle of the water receiving tray body 1 is adjusted by means of a transmission connection.

[0027] In one embodiment, a speed sensor 4 is provided on the water receiving tray body 1, and the speed sensor 4 can measure the horizontal rotation speed of the water receiving tray body 1. The driving motor 3 can adjust the rotation angle of the water receiving tray body 1 around the output shaft according to the horizontal rotation speed of the water receiving tray body 1.

[0028] In this embodiment, the horizontal rotation angular velocity of the water receiving tray body 1 can be detected in real time according to the speed sensor 4, and then the inclination angle of the condensed water surface in the water receiving tray body 1 under the speed condition can be calculated accordingly, and the inclination angle of the water receiving tray body 1 can be automatically adjusted in turn, so that the condensed water surface is always parallel to the bottom surface of the water receiving tray, ensuring that the highest point of the liquid surface does not exceed the height of the water receiving tray.

[0029] In one embodiment, the adjustment angle β of the water tray assembly is β=90°-arctan(g / ω2 r), where g is the acceleration of gravity, ω is the horizontal rotation angular velocity of the water receiving tray body 1, and r is the rotation radius of the water receiving tray body 1. Since the water receiving tray body 1 is actually used in a turntable air conditioner and is installed inside the turntable air conditioner, ω here can also be used as the air conditioner speed, which can be measured by a speed sensor, and the rotation radius r is a configurable parameter, and the user can input the actual rotation radius according to needs.

[0030] The condensed water in the water receiving tray 1 is taken as the object of force analysis. Figure 2 As shown in the figure, the condensed water is regarded as a particle, assuming that its weight is m. When it moves with the turntable at a rotation radius r and an angular velocity ω, it is mainly affected by two forces: centrifugal force F = mω 2 r, gravity G = mg, then the angle between the cooperative force and the horizontal plane is:

[0031] α=arctan(G / F)=arctan(g / ω 2 r)

[0032] Since the liquid surface of the condensed water should be perpendicular to the direction of the cooperative force at all times, the angle between the liquid surface of the condensed water and the horizontal plane is:

[0033] β=90°-α=90°-arctan(g / ω 2 r)

[0034] That is, the water tray needs to be adjusted to an angle of β = 90°-arctan(g / ω 2 r).

[0035] After calculating the angle that the water receiving pan 1 needs to be adjusted in the above manner, the water receiving pan 1 is driven by the driving motor 3 to rotate counterclockwise by β, thereby ensuring that the condensed water level remains parallel to the bottom surface of the water receiving pan 1, preventing the highest point of the liquid level from exceeding the height of the water receiving pan 1, causing the condensed water to overflow.

[0036] In one embodiment, a first drain pipe 5 is disposed at the bottom of the water receiving tray body 1 to facilitate the discharge of condensed water in the water receiving tray body 1 .

[0037] In one embodiment, the water receiving tray assembly also includes a bypass pipe 7, one end of the bypass pipe 7 is connected to the inlet of the first drain pipe 5, and the other end is connected to the top of the water receiving tray body 1. The bypass pipe 7 can be used to make the pressure at the bottom of the water receiving tray body 1 at the inlet of the first drain pipe 5 the same as the pressure at the top of the water receiving tray body 1, so that the water flow can be smoothly discharged from the first drain pipe 5 under the action of gravity.

[0038] In one embodiment, the water tray assembly further includes a second drain pipe 6 , which is connected to the bottom of the water tray body 1 , and the first drain pipe 5 and the bypass pipe 7 are commonly connected to the bottom outlet of the second drain pipe 6 .

[0039] The cross-sectional areas of the second drain pipe 6 and the bypass pipe 7 are both larger than the cross-sectional area of ​​the first drain pipe 5 .

[0040] The cross-sectional area of ​​the second drain pipe 6 decreases from top to bottom, and the minimum cross-sectional area of ​​the second drain pipe 6 is greater than the maximum cross-sectional area of ​​the first drain pipe 5 .

[0041] In one embodiment, the turntable air conditioner includes a water receiving tray assembly, and the water receiving tray assembly is the water receiving tray assembly mentioned above.

[0042] The turntable air conditioner further comprises a fan 8 and a heat exchanger 9 , and the water receiving pan assembly is located below the heat exchanger 9 .

[0043] A bypass pipe 7 is provided at the drain outlet and connected to the top of the water receiving pan 1. The diameter of the C section of the bypass pipe 7 and the diameter of the B section of the second drain pipe 6 are both larger than the diameter of the A section of the first drain pipe 5. When the fan is running, the top of the water receiving pan 1 is a negative pressure area, and the outside of the first drain pipe 5 is a positive pressure area. Due to the pressure difference, the air will flow from the A section to the B section and the C section, and the air flow Q A =Q B +Q C , due to the pipe diameter d A <d B And d A <d C , so the air velocity v A >v B And v A >v C According to Bernoulli's principle, when the air velocity is high, its pressure is low, so the pressure in section A is lower than that in sections B and C. Since section C is connected to the top of the water receiving pan 1, its pressure can be considered equal to the pressure above the water receiving pan 1. Therefore, the pressure in section A is lower than the pressure above the water receiving pan 1. Due to the pressure, the condensed water can be discharged quickly.

[0044] When the condensed water can be discharged continuously, a liquid sealing effect can be formed at various places in the first drain pipe 5, which can effectively prevent air leakage and affect the air volume of the whole machine.

[0045] In this embodiment, the function of section C of the bypass pipe 7 is to ensure that the pressure of section A of the first drain pipe 5 is lower than the pressure of the negative pressure zone above the water receiving tray body 1, and the function of section B of the second drain pipe 6 is to ensure that the pressure of section A of the first drain pipe 5 is lower than the pressure at the drain port of the water receiving tray body 1. Under the influence of the pressure difference, condensed water can be easily discharged from the drain port to section A, so that drainage is smoother.

The above are only preferred implementations of the present application.
