Problems solved by technology

[0008] However, a disadvantage of inverter-mounted automatic pumps is that they require high-priced inverters, which increases the manufacturing cost of the automatic pump and undesirably increases the size of the automatic pump

Embodiment Construction

[0022] Hereinafter, preferred embodiments of an automatic pump and an operation control method thereof according to the present invention will be described with reference to the accompanying drawings.

[0023] figure 1 is a perspective view of an automatic pump according to an embodiment of the present invention, figure 2 is along figure 1 A cross-sectional view taken along line A-A.

[0024] As shown, according to the present embodiment, the automatic pump includes a housing 110 having a first housing portion 111 and a second housing portion 115 connected to each other.

[0025] Formed respectively on opposite sides of the housing 110 are an inlet 111a for communication with a liquid source, such as water, and an outlet 115a for communication with an application site, such as a cock. More specifically, the inlet 111 a is formed at the first housing part 111 , and the outlet 115 a is formed at the second housing part 115 .

[0026] In the housing 110, the pump impeller 12...

Abstract

Disclosed are an automatic pump and an operation control method for the same. With the automatic pump and the operation control method for the same, the number of turns in the stator coil of a motor is determined by optionally switching in accordance with changes in the pressure inside the housing of an automatic pump forming a flow pathway for fluid, and thus the rotational speed of the motor is varied to whichever rotational speed is appropriate among pre-set stepped rotational speeds, or is stopped. Consequently costs are curbed and volume is reduced as there is no need for an inverter as is used in automatic pumps of the prior art.

Description

technical field [0001] The present invention relates to an automatic pump and an operation control method of the automatic pump. Background technique [0002] As known in the art, a pump refers to a device that transmits liquid through pressure action, while an automatic pump is a pump that automatically turns or stops a pump wheel for forcibly discharging introduced liquid according to preset conditions. [0003] An automatic pump has a housing forming a flow path for a liquid. In addition, a pump wheel driven by a motor is installed in the casing, and a pressure sensor for sensing the internal pressure of the casing or a flow switch for sensing the amount of liquid discharged from the casing is provided at one side of the casing. [0004] Thus, in an automatic pump, the internal pressure of the housing causes the drive motor to operate or stop, or the discharge of fluid from the housing causes the motor to run or stop, which in turn turns or stops the pump wheel.
