Embodiment Construction

[0039] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the present invention.

[0040] In the following description, the use of suffixes such as “module”, “part” or “unit” used to indicate elements is only for facilitating the description of the present invention, and has no specific meaning in itself. Therefore, "module", "part" or "unit" can be used in a mixed manner.

[0041] In order to solve the problem in the related art that when the ambient temperature is low, the condensed water cannot be discharged normally and will damage the water pump, an embodiment of the present invention provides a method for controlling the drainage of a unit, such as figure 1 As shown, the methods include:

[0042] Step S101: When it is determined that the unit needs to ...

Abstract

The invention discloses a method for controlling drainage of a unit and the unit. The method comprises the following steps that when it is determined that the unit needs to drain water off, and the temperature of the water in a water receiving tray is detected; when the temperature of the water in the water receiving tray is lower than a preset temperature, the water in the water tray is heated; and the heated water is discharged out of the water receiving tray. Therefore, when the water in the water receiving tray is frozen, and the unit has a drainage demand, the water in the water receivingtray can be heated through an electric heating device, so that the state of the water can be in a state that the water can be smoothly discharged (in a liquid state or low ice content state), then the unit can normally drain the water off, and a water pump is prevented from being damaged.

Description

Technical field [0001] The invention relates to the field of units, in particular to a method for controlling drainage of a unit and a unit. Background technique [0002] At present, condensate water is generated during the operation of the air conditioner, and the condensate water can be directly discharged through a drain pipe or through a water pump. However, when the weather becomes cold, the condensed water is easy to freeze and cannot be discharged normally, and it may even cause damage to the water pump. Especially in North America, where the temperature is low, due to factors such as beautiful outdoor design, drainage pipes arranged outside the building are usually not used to drain the condensate, but water pumps are used to drain and collect the discharged condensate To the designated location. Therefore, solving the above problems is beneficial to the promotion of air conditioners in North America and other places. [0003] Aiming at the problem that the condensed wat...
