1 and 2, the temperature control valve according to an embodiment of the present invention may include a housing 100, a control plate 200, a coil 210, and a magnet 310.

The housing 100 constitutes the exterior of the valve and may include components of the valve therein. Specifically, the housing 100 may accommodate the control plate 200, the coil 210, and the magnet 310 listed above.

Referring to FIG. 1, the housing 100 may include first and second housings 101 and 102. The first and second housings 101 and 102 may be configured to be coupled. That is, after the components are accommodated in the housing 100 in the manufacturing step of the valve, the first and second housings 101 and 102 can be rigidly assembled. In this case, a watertight device (sealing unit) may be disposed between the first and second housings 101 and 102 to prevent fluid from leaking through the gaps between the first and second housings 101 and 102.

Specifically, the housing 100 may include a hot water inlet 101a, a low temperature water inlet 101b, and a mixed water outlet 102a. In the drawing, it is shown that the hot water inlet and the low temperature water inlet 101a and 101b are formed in the first housing 101, and the mixed water outlet 102a is formed in the second housing 102, but the present invention is limited thereto. It is not.

The mixed water outlet 102a may be configured to discharge mixed water generated by mixing hot water and low temperature water to the outside of the housing 100. That is, the fluid is supplied into the housing 100 through the hot water inlet or the low temperature water inlet 101a and 101b, and the mixed water generated inside the housing 100 is discharged to the outside through the mixed water outlet 102a.

On the other hand, the hot water inlet and the cold water inlet 101a, 101b may be arranged side by side on one surface of the housing 100, and such a structure is linked to the operation of the control plate 200 to be described later, Allows you to adjust the mixing ratio.

The control plate 200 is disposed inside the housing 100 and may be configured to be rotatable about one axis 201. That is, the position of the adjustment plate 200 may be changed within the housing 100 by rotating and moving.

Specifically, the control plate 200 may be configured to rotate and move on a surface parallel to one surface of the housing 100 described above. Furthermore, at least a part of the control plate 200 may be formed as a plane, and such a plane part may be configured to rotate while contacting one surface of the housing 100. According to this configuration, the position of the control plate 200 is changed as the control plate 200 is rotated, and the degree of opening and closing of the hot water inlet and the low temperature water inlet 101a and 101b can be adjusted. Meanwhile, in order to efficiently change the opening/closing ratio of the hot and cold water inlets 101a and 101b according to the position of the control plate 200, the flat portion of the control plate 200 may have a fan shape.

The rotational movement of the control plate 200 described above may be performed by the interaction of the coil 210 and the magnet 310.

The coil 210 is disposed inside the control plate 200 and may be formed to apply a current. That is, although not shown in the drawing, the coil 210 may be connected to the power supply and formed so that a current flows when power is applied. In addition, the direction of the current flowing through the coil 210 may be clockwise or counterclockwise, that is, two directions. Meanwhile, the coil 210 may be disposed on an outer peripheral surface of a bobbin having a hollow spool shape. The coil 210 may be directly wound on the outer peripheral surface of the bobbin or adhered to the outer peripheral surface of the bobbin using an adhesive or the like.

The magnet 310 may be disposed inside the housing 100 so that at least a portion thereof faces the control plate 200. The magnet 310 forms a magnetic field around the space in which the magnet 310 is placed. For example, the magnet 310 may be made of a permanent magnet, and may be configured in the form of an electromagnet that forms a magnetic field only when electricity is passed.

In addition, the magnet 310 may be composed of at least two. Hereinafter, each of the magnets may be referred to as first and second magnets 311 and 312.

2 and 5, the first and second magnets 311 and 312 may be mounted on the lower plate 320 fixed in the housing 100. Specifically, the first and second magnets 311 and 312 may be disposed to be spaced side by side on the lower plate 320.

In addition, the first and second magnets 311 and 312 may be mounted on the lower plate 320 so that different poles face the same direction.

For example, FIG. 5 shows that when the first magnet 311 is mounted so that the N pole is arranged on the upper side and the S pole is arranged on the lower side, the second magnet 312 has an S pole on the upper side and an N pole on the lower side. It can be mounted to be placed.

Meanwhile, the upper and lower plates 220 and 320 described above may be referred to as one or the other of the first and second plates.

The first and second plates 220 and 320 may be made of a material capable of forming a magnetic flux path. For example, the first and second plates 220 and 320 may be formed of a magnetic material.

According to the arrangement of the first and second magnets 311 and 312 and the first and second plates 220 and 320 described above, a magnetic flux path having a shape as shown in FIG. 5 may be formed. That is, the magnetic flux path may be a closed path along a clockwise or counterclockwise direction. Referring to FIG. 5, the magnetic flux path is in a direction from the first magnet 311 to the second magnet 312 through the upper plate 220 and the second magnet 312 to pass through the lower plate 320. 1 may be formed in a direction entering the magnet 311. Such a magnetic flux path may pass through the coil 210.

That is, when a current flows through the coil 210 in the space where the magnetic field is formed, the coil 210 receives force in a specific direction, so that the coil 210 and the control plate 200 on which the coil 210 is mounted can move. .

Specifically, the rotational direction (moving direction) of the control plate 200 is determined according to the direction of current flowing through the coil 210, and the rotational strength (moving amount) of the control plate 200 is determined according to the current strength flowing through the coil 210. I can. That is, the position of the throttle plate 200 may be determined based on the direction or strength of the current flowing through the coil 210.

Hereinafter, the principle of rotation of the adjustment plate 200 will be described in detail with reference to FIG. 6.

6(a) and 6(b), in the coil 210, a current flows in a direction entering the ground on the side of the first magnet 311, and a direction coming out of the ground on the side of the second magnet 312 Current can flow. In this case, according to Fleming's left-hand rule, the coil 210 is moved by receiving a force from the second magnet 312 toward the first magnet 311. In this case, the amount of movement of the coil 210 may vary according to the strength of the current flowing through the coil 210.

6(b) and 6(c), in the coil 210, a current flows in a direction exiting the ground on the first magnet 311 side, and a direction entering the ground on the second magnet 312 side. Current can flow. In this case, according to Fleming's left-hand rule, the coil 210 is moved by receiving a force in a direction from the first magnet 311 to the second magnet 312. In this case, the amount of movement of the coil 210 may vary according to the strength of the current flowing through the coil 210.

Meanwhile, the sum of the areas of the first and second magnets 311 and 312 may be larger than the area of the coil 210. According to this structure, even when the coil 210 moves, the magnetic flux path can be maintained.

FIG. 7A is a view viewed from the front part of FIG. 1, and FIG. 7B is a view of the front part after removing the first case from FIG. 1.

Referring to FIG. 7A, at least a portion of the hot water inlet and the low temperature water inlet 101a and 101b is covered by the control plate 200. That is, the size of the open portions (S1, S2) of the hot water inlet and the low temperature water inlet (101a, 101b) or the ratio thereof vary depending on the position of the control plate 200, so that the mixing ratio of the hot water and the low temperature water may vary. .

Meanwhile, the temperature control valve according to an embodiment of the present invention may further include a control unit and a user input unit.

The user input unit may be configured to receive information related to the target temperature from the user. For example, the user input unit may include a unit on which an input is possible, a display, or a physical button, or may include a component for recognizing a user's voice. Alternatively, in addition to having a separate user input unit, the temperature control valve may be interlocked with the user's terminal to receive information related to the target temperature through information input by the user through an application of the terminal.

The control unit may be configured to control the direction or intensity of the current so that the control plate 200 is positioned at a position corresponding to the target temperature.

Specifically, as described above, the mixing ratio of hot water and low temperature water, that is, the temperature of the mixed water, may be determined according to the position of the control plate 200. In other words, the position of the control plate 200 and the temperature of the mixed water have a correspondence relationship, and information related to the correspondence may be previously stored in the controller. Accordingly, when information related to the target temperature is input from the user, the controller may position the control plate 200 at a position corresponding to the target temperature by referring to the information related to the correspondence relationship.

Meanwhile, referring to FIGS. 2 and 3, a sensor 400 configured to detect the position of the control plate 200 may be provided in the control plate 200. For example, the sensor 400 may be a Hall sensor or a magnetic encoder. The hall sensor is located on the rotation shaft 201 of the control plate 200 to detect the position of the rotation shaft 201 of the control plate 200.

Accordingly, the controller is configured to control the direction or intensity of the current of the coil 210 based on the current position of the control plate 200 sensed by the sensor.

For example, when a target temperature is input by a user, the controller may determine a position A of the control plate 200 corresponding to the target temperature.

At this time, when the current position of the control plate 200 detected by the sensor is B, the control unit calculates the displacement from the current position B to the position A, and determines the direction or intensity of the current of the coil 210 for generating the displacement. I can.

In addition, a temperature sensor is provided at the outlet side of the mixed water of the temperature control valve according to an embodiment of the present invention, and the control unit controls the direction or intensity of the current by comparing the temperature of the mixed water measured by the temperature sensor with a target temperature. can do.

According to this feedback-controlled configuration, it is possible to provide mixed water having a temperature that is closer to the target temperature input by the user and has an accurate temperature.

Meanwhile, referring to FIG. 8, the artificial muscle assembly 800 according to an embodiment of the present invention may include a thermal reaction driving unit 810, a fluid supply unit 820, and a temperature control valve 821.

The thermal reaction driving unit 810 may be formed of a shape memory alloy material that reacts to heat. For example, the thermal reaction driving unit 810 may be formed of a shape memory alloy wire or a shape memory alloy spring. That is, the thermal reaction driving unit 810 may be configured to contract when the temperature increases and to relax when the temperature decreases.

Alternatively, the thermal reaction driving unit 810 may include not only a shape memory alloy material, but also various thermally reactive materials that react by heat, for example, shape memory resin, shape memory polymer (SMP), It may be made of carbon nanotube, polyethylene, polyamide, nylon, or the like.

The fluid supply unit 820 may be configured to provide a fluid for temperature control of the thermal reaction driving unit 810. For example, the fluid supply unit 820 may include a flow path disposed around the thermal reaction driving unit 810. When hot water is provided from the fluid supply unit 820, the thermal reaction driving unit 810 may increase in temperature and contract. When the low temperature water is provided, the thermal reaction driving unit 810 may relax by decreasing the temperature.

The temperature control valve 821 may be configured to control the temperature of the mixed water supplied from the fluid supply unit 820. Specifically, the temperature control valve 821 may be disposed inside the fluid supply unit 820 to adjust the temperature of the mixed water supplied from the fluid supply unit 820.

According to such a configuration, since hot water or low temperature water is provided to the thermal reaction driving unit 810 very quickly so that the temperature can be adjusted, responsiveness of relaxation and contraction of the artificial muscle assembly is improved.

Hereinafter, a method of controlling a temperature control valve according to an embodiment of the present invention will be described with reference to FIG. 9.

A method of controlling a temperature control valve according to an embodiment of the present invention may include an information input step and a positioning step.

In the information input step S910, information related to the target temperature of the mixed water may be input from the user. For example, the user may input a target temperature value using a touch pad connected to a temperature control valve.

In the positioning step S920, the direction or intensity of the current flowing through the coil 210 may be determined so that the control plate 200 is positioned at a position corresponding to the target temperature.

Specifically, in the positioning step, the direction or intensity of the current flowing through the coil 210 may be determined based on the current position of the control plate 200 sensed by a sensor (eg, a Hall sensor or a magnetic encoder).

That is, when a target temperature value is input by the user, the controller may receive information about the current angle position of the control plate 200 from the sensor through the communication module. In addition, the control unit may determine a target angle position of the control plate 200 corresponding to the target temperature value and compare the current angular position information with the target angular position information to determine the direction and strength of the current of the coil 210 required. .

In addition, the method of controlling the temperature control valve according to an embodiment of the present invention may further include a feedback step.

In the feedback step S930, the direction or intensity of the current may be controlled by comparing the temperature of the mixed water measured by the temperature sensor with the target temperature.

For example, when the temperature of the mixed water measured by the temperature sensor is lower than the target temperature, the control plate 200 may be moved to the side where the hot water inlet is opened more so that the mixing ratio of the hot water is higher.
