Embodiment 1

[0024] In the preferred embodiment 1 of the present invention, an oil return control method is provided. This control method can be directly applied to various intelligent sweeping robots, and can also be applied to other devices with some functions of the sweeping robot. When specifically implemented, It can be realized by installing software, APP on the sweeping robot or other devices, or writing the corresponding program of the sweeping robot or other device controllers. Specifically, figure 1 An alternative flowchart showing the method, such as figure 1 As shown, the method includes the following steps S102-S106:

[0025] S102: Obtain the start-up time and the accumulative running time of the unit during start-up;

[0026] S104: Determine the relationship between the start-up time and the silent interval set by the user and whether the accumulated running time reaches the standard oil return time;

[0027] S106: Execute a corresponding oil return control strategy accord...

Embodiment 2

[0060] Based on the oil return control method provided in the above-mentioned embodiment 1, an oil return control device is also provided in the preferred embodiment 2 of the present invention, specifically, image 3 shows an optional structural block diagram of the device, such as image 3 As shown, the device includes:

[0061] Obtaining module 302, for obtaining the accumulative running time of the unit when starting up time and starting up;

[0062] Judgment module 304, connected with acquisition module 302, is used for judging the relationship between power-on time and the silent interval set by the user and whether the cumulative running time reaches the standard oil return time;

[0063] The oil return module 306 is connected with the judging module 304, and is used for executing a corresponding oil return control strategy according to the judgment result.

[0064] In the above embodiment, an oil return control scheme is provided, including: obtaining the start-up tim...

Embodiment 3

[0075] Based on the oil return control device provided in the above-mentioned embodiment 2, in preferred embodiment 3 of the present invention, there is also provided an air conditioning unit, including the above-mentioned oil return control device.

[0076]In the above embodiment, an oil return control scheme is provided, including: obtaining the start-up time and the cumulative running time of the unit at start-up, and judging the relationship between the start-up time and the silent interval set by the user and whether the cumulative running time reaches the standard oil return time, execute the corresponding oil return control strategy according to the judgment result. Through the above scheme, the impact of oil return on the silent interval set by the user is reduced, so as to solve the problem that the multi-line oil return in the prior art will cause discomfort to the user, improve the comfort of the user, and ensure the reliable operation of the unit at the same time. ...

Abstract

The invention discloses an effective oil return control method, an oil return control device and an air conditioner unit, wherein the method comprises the following steps of obtaining a turn-on time and the accumulated operation time of the air conditioner unit when the air conditioner unit is turned on; judging the relationship between the turning-on time and a mute interval set by a user and whether the accumulated operation time reaches the standard oil return time or not; and executing a corresponding oil return control strategy according to a judging result. The problem that discomfort ofthe user can be caused by VRV oil return in the prior art can be solved; the user comfort is improved; and meanwhile, reliable operation of the air conditioner unit is ensured.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an effective oil return control method, device and air conditioning unit. Background technique [0002] In actual engineering installation, multi-connected units are often equipped with long connecting pipes, or the height difference between indoor and outdoor units is high, and some indoor units are turned on for a long time. In order to ensure the long-term effective operation of the unit, the oil return of the multi-connected system has become very necessary. And the key technology. [0003] However, the oil return of the system often brings a lot of noise. If it coincides with a special time such as a user's rest, it will cause discomfort to the user. How to find a balance between multi-line oil return and user habits has become a very important way to improve product comfort. [0004] Aiming at the problem in the related art that multiple online oil return will ca...
