Description

Water pump controller with compact structure

Technical Field

The utility model relates to the technical field of water pump manufacturing, in particular to a water pump controller with a compact structure.

Background

It is known that, in the existing water supply system of the water pump, in order to realize the normal operation and automatic control of the water pump, a controller for controlling the operation state of the water pump needs to be configured, so as to start the water pump to operate to supply water according to the downstream water demand, or to shut down the water pump to stop supplying water, thereby avoiding the water pressure of the pipeline from being too high, and the load of the water pump from being too large to cause waste or even damage. In order to set up the parameters of water pump operation and the like conveniently, at present, water pump controllers are mostly arranged outside water pump motors. The existing water pump controller generally includes a housing, and a control circuit board for controlling the operation of a water pump motor is disposed in the housing. It can be understood that the control circuit board can generate more heat during operation and needs to dissipate heat accordingly, and especially, in order to improve the working efficiency of the water pump and reduce the power consumption, people usually adopt frequency conversion control on the water pump motor. Correspondingly, the control circuit board at the moment also plays the role of a power supply board, and more heat can be generated during operation. In order to ensure the heat dissipation of the control circuit board, people usually set a corresponding heat sink in the housing of the controller, the control circuit board is set on the heat sink, and the housing is set with heat dissipation holes.

However, the existing controller structure still has the following defects in terms of heat dissipation: because control circuit board can produce more heat, consequently, need set up the great heating panel of overall dimension and corresponding shell body to increase water pump controller's overall dimension and manufacturing cost, to some narrow installation space, can cause the difficulty of water pump installation even.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the problem that the conventional water pump controller has larger overall dimension so as to limit the applicable installation space, and provides a water pump controller with a compact structure.

In order to achieve the purpose, the utility model adopts the following technical scheme:

the utility model provides a compact structure's water pump controller, its control that is applicable to the water pump that has driving motor, includes shell body, motor control panel, driving motor includes motor housing, sets up stator and rotor in motor housing, supplies the heat dissipation passageway of cooling air circulation, is equipped with the control chamber that is close to the motor housing inside wall and is used for arranging the working chamber of stator and rotor in motor housing, motor control panel sets up in the control chamber, motor control panel pastes motor housing's inside wall in the control chamber.

It will be appreciated that the motor housing for the drive motor is much larger in size relative to the water pump controller housing. Besides, the motor shell is provided with a stator and a rotor, and is also provided with a heat dissipation channel for dissipating heat of the rotor, the stator and the like. Of course, a corresponding heat dissipation fan is also required to be arranged in the heat dissipation channel. When the heat radiation fan runs, the external cold air can be sucked inwards, so that the components such as the rotor, the stator and the like in the heat radiation fan are cooled. That is, the motor housing should be provided with an air inlet and an air outlet, thereby forming a heat dissipation channel. In addition, the motor shell plays a good heat dissipation role for the rotor and the stator.

The utility model creatively removes a main heating element in the water pump controller, namely the motor control board, from the shell body and arranges the motor control board in the shell body of the motor. On the premise of not influencing the overall size of the motor shell, the heat dissipation effect of a heat dissipation channel in the motor shell is fully utilized, so that the motor control board can be cooled by heat dissipation well. And the size of the outer shell of the water pump controller is obviously reduced, so that the water pump with the water pump controller can be suitable for different installation spaces.

It should be noted that, when the motor control board is disposed in the control cavity in the motor housing, we only need to electrically connect the motor control board and the water pump controller, and then all the existing functions, effects and actions of the water pump controller can be realized without any improvement on the other structures, and particularly, without adding new structural features, thereby not increasing the overall manufacturing cost.

Preferably, a control cover body connected with the motor shell through screws is arranged on the motor shell corresponding to the control cavity, the motor control panel is attached to the inner side wall of the control cover body, and the outer shell is connected with support columns arranged on the outer side wall of the control cover body through screws.

The utility model is provided with an openable control cover body on the motor shell corresponding to the control cavity. Like this, when needing to install the motor control board, only need dismantle the control lid, then with motor control board fixed mounting in the inboard of control lid, again will control for the lid fix with screw on motor casing, make the motor casing appearance keep complete on the one hand, on the other hand can make the motor control board paste and lean on the control lid inside wall to the heat that is favorable to the motor control board gives off through control lid and motor housing, and then improves the radiating efficiency of motor control board.

Because the shell body of the water pump controller is arranged on the supporting column on the outer side wall of the control cover body, a certain gap can be formed between the shell body of the water pump controller and the motor shell, heat of the motor shell is prevented from being conducted to the shell body of the water pump controller, and meanwhile the water pump controller is convenient to stably install.

Preferably, a power factor correction plate is further arranged in the control cavity.

The power factor correction plate can effectively adjust and correct the power factor of the driving motor, and further improve the efficiency of the driving motor. The utility model arranges the power factor correcting plate which generates more heat in the control cavity, thereby not only reducing the external dimension of the shell of the water pump controller, but also being beneficial to the heat dissipation and cooling of the power factor correcting plate.

Preferably, the motor control board and the power factor correction board are arranged side by side.

When the motor control board and the power factor correction board are arranged side by side, the thickness of the control cavity can be effectively reduced, the arrangement in the motor shell is convenient, and the heat dissipation of the driving motor can not be adversely affected. It will be appreciated that the motor housing is generally cylindrical, and in this case, the motor control board and the power factor corrector board, which are arranged side by side, are arranged around the central axis of the motor housing, and an angle is formed between the motor control board and the power factor corrector board. Even, the motor control board and the power factor correction board are approximately symmetrically arranged on the inner side wall of the motor shell, so that uniform cooling and heat dissipation are facilitated.

Preferably, the motor housing comprises a main body section and a control section, the main body section is close to one end of the water pump and provided with a working cavity, the control section is far away from one end of the water pump and provided with a control cavity, a shuttle-shaped flow guide cone is arranged at the center of the end face of the inner side of the control section, an annular heat dissipation channel is formed between the flow guide cone and the inner side wall of the motor housing, a plurality of ventilation holes are formed in the end face of the control section and located in the heat dissipation channel, and the control cavity is located in the heat dissipation channel.

In this scheme, we set up a water conservancy diversion awl in the control section to form annular heat dissipation channel between water conservancy diversion awl and motor housing inside wall, when radiator fan moves, external cold air can get into in the heat dissipation channel through the ventilation hole, carries out effectual cooling to the control chamber that is located the heat dissipation channel on the one hand, dispels the heat to stator and rotor in the main part section simultaneously and cools off.

Therefore, the utility model has the following beneficial effects: on the basis of ensuring that the original function and effect of the controller are not changed, the overall dimension of the controller can be obviously reduced, so that the controller is suitable for different installation spaces.
