The terms or words used in the present invention described below cannot be construed restrictively into general or dictionary meanings, and must be interpreted by meanings and concepts conforming to the technical idea of the present invention, based on the principle that the inventor properly defines the concepts of the terms in order to explain his invention by the most preferable method.
Therefore, the embodiments described in the present specification and the configurations shown in the drawings are only preferred embodiments of the present invention and do not replace the technical idea of the present invention, and therefore, it is to be understood that there are many equivalent technical solutions and modifications that can replace these at the point of view of the present application.
Fig. 1 is a perspective view of a pump-integrated submersible motor 1 operated by wireless power according to the present invention, and fig. 2 is an exploded perspective view, and the present invention includes a body 10, in which a space for installing components is formed in the body 10, and a water shortage detection sensor 11 for detecting a water shortage is installed on an outer surface of the body 10. The water shortage detection sensor 11 may utilize a water level detection sensor for detecting a water level.
The power generation and data transmission unit 14 is detachably provided in the main body 10, and the power generation and data transmission unit 14 receives wireless power to supply a motor driving power source, and when the water shortage is detected by the water shortage detection sensor 11, the supply of the motor driving power source is cut off, and the transmission of the water shortage data is controlled.
As shown in fig. 3, the power generation and data transmission unit 14 includes: a wireless power receiving unit 21 for wirelessly receiving power and data; the power generation unit 22 generates and supplies driving power from the wireless power received by the wireless power reception unit 21; a motor driving unit 23 for supplying the electric power generated by the electric power generating unit 22 to motor driving electric power; and a control unit 24 for controlling the supply of motor driving power to the motor driving unit 23 based on the output signal of the water shortage detection sensor 11, and transmitting the water shortage data through the wireless power receiving unit 21 when the water shortage is detected by the water shortage detection sensor 11.
A pump-integrated motor 15 that moves water by being driven by the electric power supplied from the electric power generation and data transmission unit 14 is built in the body 1.
The main body 10 is provided with the power generation and data transmission unit 14 and the pump-integrated motor 15, and is subjected to water repellent treatment.
In the figure, unexplained reference numeral 16 denotes a water inlet 16, 12 denotes a drain port, and 13 denotes a cover.
The body 10 is covered with the cover 13 with the power generation and data transmission unit 14 and the pump-integrated motor 15 built therein, and is sealed with a finish material to complete the waterproof treatment.
The body 10 is made of a plastic material into which moisture hardly flows, and thus, a waterproof process can be performed.
The water flowing into the water inlet 16 flows only into the pump-integrated motor 15, and is discharged to the water outlet 12 connected to the pump-integrated motor 15 to move the water. Therefore, in a state where the water inlet 16 or the drain port 12 is opened, water does not flow into the body 10.
The operation of the pump-integrated submersible motor operated by wireless power according to the present invention as described above will be specifically described as follows.
First, the body 10 is covered with the cover 13 with the power generation and data transmission unit 14 and the pump-integrated motor 15 built therein, and is sealed with a finish material to complete the waterproof treatment.
Thereafter, when power is wirelessly transmitted from an additional wireless power transmitter, the wireless power is received by the wireless power receiving unit 21 of the power generation and data transmission unit 14.
As a method for wirelessly receiving and generating electric power, an electric wave type using radio waves (microwaves), a magnetic energy magnetic induction type using a magnetic energy coupling method using a primary coil on a transmission side and a secondary coil on a reception side, and a magnetic resonance type transmitting electric power in a magnetic energy form by concentrating energy at a specific resonance frequency of an inductor L and a capacitor C using a coil type can be used.
In the present invention, the above-described three methods can be used as a method for wirelessly receiving power, and in the present invention, for convenience of explanation, it is assumed that a magnetic resonance type is used.
The wireless power received by the wireless power receiving unit 21 is processed by the power generating unit 22 to generate drive power. The drive power thus generated is also used as motor drive power, and is supplied to the control unit 24 as an operating power supply.
When receiving the operating power, the controller 24 checks the water level state in conjunction with the water shortage detection sensor 11. As a result of the confirmation, if the water level is normal, the electric power generator 22 is controlled to supply the driving electric power to the motor driver 23. For this purpose, the power generation unit 22 includes a relay or other power switch, and the relay or power switch is turned on (on) or off (off) to supply or cut off the drive power to the motor drive unit 23 under the control of the control unit 24. When the water level is normal, the relay or the power switch is turned on, and the driving power is supplied to the motor driving unit 23. The power supply to the motor drive unit 23 may be performed by a continuous power supply method or by a method of supplying or interrupting power at predetermined intervals by the limitation of the relay or the power switch. When the system of supplying or cutting off power at a predetermined cycle is used, power saving can be achieved.
When the driving power is supplied, the motor driving unit 23 outputs the motor driving power, and operates the pump-integrated motor 15 in conjunction with the output of the motor driving power, thereby moving the water.
On the other hand, when the water level is detected by the water shortage detection sensor 11 and the water is in a shortage state, the electric power generator 22 is controlled to prevent the driving electric power from being supplied to the motor driver 23.
That is, when the control unit 24 determines that the water is insufficient by the water shortage detection sensor 11, the pump-integrated motor 15 is stopped by supplying the driving power to the motor driving unit 23 by automatically turning off the power generating unit 22 as described above, and the water shortage Data (Tx Data) is generated to notify the outside of the water shortage. The water shortage data thus generated realizes wireless data transmission by the wireless power receiving unit 21.
As a method of transmitting the water shortage data by the wireless power receiving unit 21, a method of modulating the water shortage data by using a wireless power signal as a carrier wave and transmitting the water shortage data by the carrier wave can be used. The technology of transmitting wireless data using a wireless power receiver may use a known technology, for example, a wireless communication function explained in korean patent No. 10-1084904 (granted 11/2011, a wireless power transmitting/receiving device having a communication function and a wireless power transmitting/receiving method thereof).
As described above, the pump-integrated submersible motor operated by wireless power according to the present invention is embodied as a pump-integrated submersible motor driven by wireless power, and in the case of insufficient water, the water shortage data is transmitted by a wireless power transmission and reception method, whereby wireless data communication can be performed without using an additional communication interface. Meanwhile, the pump-integrated submersible motor is embodied by wireless power, so that the convenience of waterproof treatment and waterproof performance can be achieved without using a wired cable, and the structure of the submersible motor can be simplified by removing the wired cable by using wireless power.
Fig. 4 is a configuration diagram of a pump-integrated submersible motor control apparatus of the present invention that operates by wireless power, and the present invention includes: a pump-integrated submersible motor 1 that operates by wireless power to move water, and transmits water shortage data when water shortage is detected; and a wireless power transmitter 2 wirelessly supplying power to the pump-integrated submersible motor 1, and displaying a water shortage state when receiving water shortage data transmitted from the pump-integrated submersible motor 1.
In fig. 4, unexplained reference numeral 3 is a water tank.
The structure and operation of the pump-integrated submersible motor 1 are the same as those of the pump-integrated submersible motor operated by wireless power shown in fig. 1 to 3.
For example, the pump-integrated submersible motor 1 includes a body 10, a space for installing components is formed inside the body 10, and a water shortage detection sensor 11 for detecting a water shortage is provided on an outer surface of the body 10. The water shortage detection sensor 11 may utilize a water level detection sensor for detecting a water level.
The power generation and data transmission unit 14 is detachably mounted on the inner surface of the main body 10, the power generation and data transmission unit 14 receives wireless power to supply a motor driving power source, and when the water shortage detection sensor 11 detects a water shortage, the supply of the motor driving power source is cut off to control the transmission of the water shortage data.
As shown in fig. 3, the power generation and data transmission unit 14 includes: a wireless power receiving unit 21 for wirelessly receiving power and data; a power generation unit 22 for generating and supplying driving power from the wireless power received by the wireless power reception unit 21; a motor drive unit 23 for supplying the electric power generated by the electric power generation unit 22 as motor drive electric power; and a control unit 24 for controlling the motor driving power supply of the motor driving unit 23 based on the output signal of the water shortage detection sensor 11, and transmitting the water shortage data through the wireless power receiving unit 21 when the water shortage is detected by the water shortage detection sensor 11.
A pump-integrated motor 15 that moves water by being driven by the electric power supplied from the electric power generation and data transmission unit 14 is built in the body 1.
The main body 10 is provided with the power generation and data transmission unit 14 and the pump-integrated motor 15, and is subjected to waterproof treatment.
In the figure, unexplained reference numeral 16 denotes a water inflow port 16, 12 denotes a discharge port, and 13 denotes a cap.
The body 10 is covered with the cover 13 with the power generation and data transmission unit 14 and the pump-integrated motor 15 built therein, and is sealed with a finish material to complete the waterproof treatment. Wherein the body 10 is removed using a plastic material that hardly flows in moisture, thereby implementing a waterproof process.
When the water flowing into the water inlet 16 flows only into the pump-integrated motor 15, the water is moved to be discharged to the water outlet 12 connected to the pump-integrated motor 15. Therefore, in a state where the water inlet 16 or the drain port 12 is opened, water does not flow into the body 10.
As shown in fig. 5, the wireless power transmitter 2 includes: a power switch 32; a water purification mode selection switch 33 for selecting a water purification mode; a wireless power transmitting unit 31 for converting commercial power inputted according to the water purification mode selected by the water purification mode selection switch 33 into wireless power and transmitting the wireless power according to the water purification mode when the power switch 32 is turned on, and for receiving data wirelessly transmitted from the pump-integrated submersible motor 1; a control unit 34 for storing the wireless data received from the wireless power transmitting unit 3 and controlling the display of the water purification mode and the water shortage state; and a mode state display unit 35 for visually displaying the water purification mode and the water shortage state according to the control of the control unit 34.
The wireless power transmitting unit 31 includes: an antenna 31b that wirelessly transmits power and receives wireless data; a power conversion unit 31a for converting a commercial power source into a wireless power signal and transmitting the wireless power signal via the antenna 31 b; and a Data receiving unit 31c that receives the carrier wave received by the antenna 31b and transmits received Data (Rx Data) to the control unit 34 by signal processing.
The pump-integrated submersible motor control device according to the present invention, which operates by wireless power, is described in detail as follows.
First, the pump-integrated submersible motor 1 is placed in a device having water, for example, the water tank 3, and then the wireless power transmitter 2 is provided so as to correspond to the lower surface of the pump-integrated submersible motor 1. First, the wireless power transmitter 2 may be attached to a predetermined position in the lower part of the water tank 3, and the pump-integrated submersible motor 1 may be attached to the upper part.
Is located in a direction in which the wireless power transmitting direction of the wireless power transmitter 2 faces the wireless power receiving portion 21 of the pump-integrated submersible motor 1.
In this state, the user turns on the power switch 32 provided to the wireless power transmitter 32, and at the same time, selects the water purification mode by the water purification mode selection switch 33.
The present invention is described in detail below with reference to the accompanying drawings, in which the present invention is applied to a submersible motor with a pump integrated therein, and the present invention is not limited to the above-described embodiment.
Wherein, the water purification mode includes a continuous mode for continuously supplying purified water and an intelligent mode for supplying purified water according to a specified period.
When the power switch 32 is turned on, the control unit 34 controls the wireless power transmitting unit 31 according to the water purification mode selected by the water purification mode selection switch 33, and generates a display control signal of the selected water purification mode to display the generated display control signal on the mode state display unit 35.
The mode state display unit 35 includes: a light emitting diode LED1 for displaying a continuous mode; a light emitting diode LED2 for displaying the smart mode; and a light emitting diode LED3 for displaying a water shortage state.
The controller 34 selectively turns on 3 of the light emitting diodes to display the corresponding water purification mode and the presence or absence of water shortage, based on the selected water purification mode and whether or not the water shortage data is received from the pump-integrated submersible motor 1.
On the other hand, when the water purification mode is the continuous mode, the control unit 34 continuously operates the power conversion unit 31a of the wireless power transmission unit 31 to continuously transmit wireless power through the antenna 31 b. Meanwhile, when the water purification mode is the smart mode, the power conversion unit 31a of the wireless power transmission unit 31 is opened and closed at predetermined intervals according to a predetermined internal control program, and wireless power is transmitted at predetermined intervals through the antenna 31 b. The wireless power transmission method is explained by the above-mentioned known techniques (for example, korean patent No. 10-1084904, 11/2011, a wireless power transmitting/receiving device having a communication function, and a wireless power transmitting/receiving method thereof).
When power is transmitted wirelessly from the wireless power transmitter 2, wireless power is received by the wireless power receiving unit 21 in the power generation and data transmission unit 14 of the pump-integrated submersible motor 1.
The wireless power received from the wireless power receiving unit 21 is processed by the power generating unit 22 to generate drive power. The drive power thus generated is used as drive power, and at the same time, the control section 24 is supplied with operating power. Wherein, wireless power is received according to the water purification mode continuous reception or according to regulation cycle.
When the operating power is supplied, the controller 24 operates in conjunction with the water shortage detection sensor 11 to check the water level state. As a result of the confirmation, if the water level is normal, the electric power generator 22 is controlled to supply the driving electric power to the motor driver 23. For this purpose, the power generation unit 22 includes a relay or other power switch, and the relay or power switch is turned on (on) or off (off) to supply or cut off the drive power to the motor drive unit 23 under the control of the control unit 24. When the water level is normal, the relay or the power switch is turned on, and the driving power is supplied to the motor driving unit 23. The power supply to the motor drive unit 23 may be performed by a continuous power supply method or by a method of supplying or interrupting power at predetermined intervals by the limitation of the relay or the power switch. When the system of supplying or cutting off power at a predetermined cycle is used, power saving can be achieved.
The drive power supplied to the motor drive unit 23 also corresponds to the water purification mode, and when the water purification mode is in the continuous mode, the drive power is continuously supplied, and when the smart mode is processed, the drive power is supplied at predetermined intervals. In the smart mode, the drive power is supplied or cut off at predetermined intervals, and therefore, power saving can be achieved for the continuous mode.
When the driving power is supplied, the motor driving unit 23 supplies a motor driving power source, and the pump-integrated motor 15 operates to move the water in conjunction with this.
On the other hand, when the water level is detected by the water shortage detection sensor 11 and the water is in a shortage state, the electric power generator 22 is controlled to prevent the transmission of the driving electric power to the motor driver 23.
That is, when the control unit 24 determines that the water is insufficient by the water shortage detection sensor 11, the pump-integrated motor 15 is stopped by supplying the driving power to the motor driving unit 23 by automatically turning off the power generating unit 22 as described above, and the water shortage Data (Tx Data) is generated to notify the outside of the water shortage. The water shortage data thus generated realizes wireless data transmission by the wireless power receiving unit 21.
As a method of transmitting the water shortage data by the wireless power receiving unit 21, a method of modulating the water shortage data by using a wireless power signal as a carrier wave and transmitting the water shortage data by the carrier wave can be used. The technology of transmitting wireless data using a wireless power receiver may use a known technology, for example, a wireless communication function explained in korean patent No. 10-1084904 (granted 11/2011, a wireless power transmitting/receiving device having a communication function and a wireless power transmitting/receiving method thereof).
The data receiving unit 31c in the wireless power transmitting unit 31 of the wireless power transmitter 2 receives and processes the water shortage data transmitted from the pump-integrated submersible motor 1, demodulates the water shortage data, and transmits the demodulated data to the control unit 34.
When the controller 34 receives the water shortage data, the light emitting diode LED3 for informing the water shortage data through the mode state display 35 is turned on, so that the user can recognize the water shortage in real time. In this case, when receiving the water shortage data, the user is notified more effectively by the notification in conjunction with a notification device such as a buzzer, if necessary.
As described above, the pump-integrated submersible motor control apparatus according to the present invention, which operates by wireless power, is embodied as a pump-integrated submersible motor driven by wireless power, and transmits water shortage data by wireless power transmission and reception in the case of water shortage, for example, whereby wireless data communication can be performed without using an additional communication interface. Meanwhile, the pump-integrated submersible motor is embodied by wireless power, so that the convenience of waterproof treatment and waterproof performance can be achieved without using a wired cable, and the structure of the submersible motor can be simplified by removing the wired cable by using wireless power.
Meanwhile, the water purification mode is divided into a continuous mode and an intelligent mode, and the water purification mode is operated according to the selection of a user, so that the functions can be improved, and the convenience of the user can be improved.
The present invention is not limited to the above embodiments, and it will be apparent to those skilled in the art to which the present invention pertains that various modifications can be made without departing from the spirit and scope of the invention.
Industrial applicability
The present invention is applicable to a technology for improving water resistance by removing an externally exposed element from water using wireless power.
