Referring to FIG. 1b, the straight pull water valve 100 of the present invention can be applied to an inductive water supply device 200 and an inductive water supply method. The inductive water supply device 200 includes a housing 210, an inductor 220, the direct pull water valve 100, a water supply pipe 230, and a control unit 240.

The housing 210 includes a water supply port 211, a first-class channel 212, and a water inlet 213. The water supply port 211 communicates with the water inlet 213 via the flow channel 212.

The sensor 220 can be an infrared sensor or a microwave sensor for sensing an external object and generating an inductive signal. In the present embodiment, the sensor 220 is disposed on the housing 210, but is not limited thereto.

In the embodiment, the temperature sensor 242 is disposed in the inner portion 114 of the valve body 110 of the direct-drawing water valve 100, but is not limited thereto. The temperature sensor 242 is electrically connected to the controller 243 to sense the temperature of the feed water of the direct-drawing water valve 100 or the temperature of the water supply to the inductive water supply device 200. After the water valve 100 or the inductive water supply device 200 supplies the temperature of the water, a temperature sensing signal is generated, so that the controller 243 controls the driving unit 140 to drive the push rod 141 to push and pull according to the temperature sensing signal. To control the amount of water entering the cold water inlet 111 and the hot water inlet 112 (that is, controlling the proportion of water entering the cold water inlet 111 and the hot water inlet 112), or controlling whether the water outlet interface 131 is out of water. The display panel 241 is electrically connected to the controller 243 for displaying a set temperature and a temperature sensed by the temperature sensor 242. In the embodiment, the display panel 241 is disposed on the side of the housing 210. For example, but not limited to, the user can view the set temperature and the temperature sensed by the temperature sensor 242.

Hereinafter, several embodiments will be described to describe the control mode of the feed water temperature of the water supply and the inductive water supply method of the inductive water supply device 200, and in the following control mode, the initial state of each of the straight pull type water valves is not water supply state. For example, the water stopping element 151j blocks the water outlet interface 131.

Mode 1: Cold water supply and water stop mode. Please refer to Figure 2.

It is assumed that the controller 243 has been previously set to cold water (for example, a temperature of 25 ° C). When the foreign object (e.g., hand 300) is within the first distance range d1 (e.g., d1 is a range from 3 cm to 10 cm from the sensor 220) relative to the inductor 220, the sensor 220 generates the The inductive signal is a water supply signal, which in turn causes the inductive water supply device 200 to supply water.

In detail, the controller 243 controls the driving unit 140 of the direct-drawing water valve 100 to drive the push-pull rod 141 to pull back directly according to the water supply signal provided by the sensor 220, so that the push-pull rod 141 drives the card. The 榫151c further indirectly drives the shaft 151 and the water stopping unit 152 to move the water stopping element 151j away from the water outlet interface 131. At the same time, the core ring 152b only blocks the hot water inlet 112, so that the cold water of the cold water pipe 231 flows out through the cold water inlet 111, the inner 114, the port 152d and the water outlet port 131. The water valve 100 is further flowed out through the water inlet 213, the flow channel 212 and the water supply port 211 of the casing 210 to provide cold water to the inductive water supply device 200.

When the foreign object is away from the sensor 220 and away from the first distance range d1, the sensing signal is a water stop signal, so that the inductive water supply device 200 stops the water supply. In detail, the controller 243 controls the driving unit 140 of the direct-drawing water valve 100 to drive the push-pull rod 141 to directly push according to the water stop signal provided by the sensor 220, so that the push-pull rod 141 drives the card. The 榫151c further indirectly drives the shaft 151 and the water stopping unit 152, and the water stopping element 151j blocks the water outlet port 131, and stops the water supply device 100 and the inductive water supply device 200 from supplying water.

Mode 2: Warm water supply and water stop mode, please refer to Figure 3.

When the foreign object (for example, the hand 300) is in the first distance range d1 (for example, 3 to 10 cm) relative to the sensor 220, the sensing signal generated by the sensor 220 is a water supply signal, and the controller 243 The driving unit 140 that controls the straight-type water valve 100 according to the water supply signal drives the push-pull rod 141 to pull back straight, so that the push-pull rod 141 drives the click 151c, thereby indirectly driving the shaft 151 and the water stop. The unit 152 moves the water stopping element 151j away from the water outlet interface 131. At the same time, the push-pull rod 141 indirectly controls the core ring 152b to block the cold water inlet 111 and the hot water inlet 112, so that the cold water of the cold water pipe 231 and the hot water of the hot water pipe 232 flow into the cold water inlet 111 and The hot water inlet 112 flows into the inner portion 114 of the valve body 110 and then flows out of the straight pull water valve 100 through the water outlet port 131, and then passes through the water inlet 213, the flow channel 212 of the housing 210, and the The water supply port 211 flows out to provide warm water to the inductive water supply device 200.

When the foreign object is away from the sensor 220 and away from the first distance range d1, the sensing signal is a water stop signal, and the controller 243 controls the direct pull type according to the sensor 220 providing the water stop signal. The driving unit 140 of the water valve 100 drives the push-pull rod 141 to directly advance, so that the push-pull rod 141 drives the latch 151c, thereby indirectly driving the shaft 151 and the water stop. The unit 152 blocks the water stopping element 151j to block the water outlet port 131, and stops the water pumping device 100 and the inductive water supply device 200 from supplying water.

Mode 3: Hot water supply and water stop mode, please refer to Figure 4.

It is assumed that the controller 243 is preset to give hot water (for example, a temperature of 45 ° C). When the foreign object (for example, the hand 300) is in the first distance range d1 (for example, 3 to 10 cm) relative to the sensor 220, the sensing signal generated by the sensor 220 is a water supply signal, and the controller 243 The driving unit 140 that controls the straight-type water valve 100 according to the water supply signal drives the push-pull rod 141 to pull back straight, so that the push-pull rod 141 drives the click 151c, thereby indirectly driving the shaft 151 and the water stop. The unit 152 moves the water stopping element 151j away from the water outlet interface 131. At the same time, the push-pull rod 141 indirectly controls the core ring 152b, and only the cold water inlet 111 is blocked, so that the hot water of the hot water pipe 232 flows out through the hot water inlet 112, the inner 114 and the water outlet interface 131. The pull water valve 100 flows out through the water inlet 213, the flow passage 212 and the water supply port 211 of the casing 210 to supply hot water to the inductive water supply device 200.

When the foreign object is away from the sensor 220 and away from the first distance range d1, the sensing signal is a water stop signal, and the controller 243 controls the direct pull type according to the sensor 220 providing the water stop signal. The driving unit 140 of the water valve 100 drives the push-pull rod 141 to directly advance, so that the push-pull rod 141 drives the cassette 151c, thereby indirectly driving the shaft center 151 and the water stopping unit 152 to block the water stopping element 151j. The water outlet port 131 stops the water supply device 100 and the inductive water supply device 200 from supplying water.

Mode 4: Continuous water supply and water stop mode, please refer to Figure 5.

This mode 4 is only exemplified by the continuous supply of cold water, and when the mode 4 is performed, the above modes 1 to 3 are ignored, that is, the weight of the mode 4 is greater than the mode 1 to 3.

When the foreign object (for example, the hand 300) is firstly opposed to the inductor 220 for a second distance range d2 (for example, d2 is a range from 0 cm to 2 cm from the sensor 220), and the stay does not exceed one. First time For example, when the signal is 2 seconds, the sensing signal is a continuous water supply signal, so that the inductive water supply device 200 continues to supply water.

In detail, the controller 243 controls the driving unit 140 of the direct-drawing water valve 100 to drive the push-pull rod 141 to pull back directly according to the continuous water supply signal provided by the sensor 220, so that the push-pull rod 141 drives the The cassette 151c further indirectly drives the shaft 151 and the water stopping unit 152 to move the water stopping element 151j away from the water outlet port 131. At the same time, the core ring 152b only blocks the hot water inlet 112, so that the cold water of the cold water pipe 231 flows out of the cold water inlet 111, the inner 114, the port 152d and the water outlet port 131. The valve 100 flows out through the water inlet 213, the flow passage 212 and the water supply port 211 of the casing 210 to supply the inductive water supply device 200 with cold water.

When the foreign object is in the second distance range d2 for the second time relative to the sensor 220, and the stay does not exceed the first time, the sensing signal is a water stop signal, thereby stopping the inductive water supply device 200. Give water. In detail, the controller 243 controls the driving unit 140 of the direct-drawing water valve 100 to drive the push-pull rod 141 to directly push according to the water stop signal provided by the sensor 220, so that the push-pull rod 141 drives the card. The 榫151c further indirectly drives the shaft 151 and the water stopping unit 152, and the water stopping element 151j blocks the water outlet port 131, and stops the water supply device 100 and the inductive water supply device 200 from supplying water.

Mode 5: Temperature control mode, please refer to Figure 5.

When mode 5 is performed, the above modes 1 to 4 are ignored, that is, the weight of mode 5 is greater than mode 1 to 4.

When the foreign object (for example, the hand 300) is in the second distance range d2 relative to the sensor 220 and stays longer than the first time, the sensing signal is a temperature increasing signal, and the inductive water supply device 200 is supplied with water. The temperature will continue to increase by a set temperature, and the set temperature will be recorded as the initial temperature of one of the feed waters of the inductive water supply device 200.

For example, if the temperature set by the inductive water supply device 200 is 25 ° C at the beginning, when the foreign object (for example, the hand 300) is opposite to the sensor 220 In the second distance range d2, and staying longer than the first time, the temperature control mode is entered, and the sensor 220 senses the time the foreign object stays and continues to increase the temperature (for example, 1 ° C per second). And the temperature is displayed on the display panel 241 to facilitate the user to adjust to the temperature of the desired water (eg, 35 ° C, ie, the set temperature).

Then, the controller 243 controls the driving unit 140 to drive the push-pull rod 141 to perform a reciprocating operation according to the set temperature, so as to indirectly control the core ring 152b through the shaft core 151 and the connector 152a. The core ring 152b adjusts the water inflow ratio of the cold water inlet 111 and the hot water inlet 112.

In this embodiment, the temperature sensor 242 continuously senses the temperature of the water supply to the inductive water supply device 200. When the temperature reaches the set temperature, the temperature sensor 242 sends a temperature sensing signal to enable the control. The driving unit 140 controls the driving unit 140 to drive the push-pull rod 141 according to the temperature sensing signal, thereby controlling the core ring 152b to adjust the water inlet ratio of the cold water inlet 111 and the hot water inlet 112 to make the temperature of the water supply of the inductive water supply device 200. It can be stabilized at this set temperature. In an embodiment, the controller 243 can include a PID controller to precisely control the temperature of the feed water of the inductive water supply device 200.

In another embodiment, when the foreign object (for example, the hand 300) is again in the second distance range d2 relative to the sensor 220, and stays longer than the first time, the sensing signal is a temperature decrease. The signal is such that the temperature of the feed water of the inductive water supply device 200 is continuously reduced to a set temperature, and the set temperature is recorded as an initial temperature of the water supply of the inductive water supply device 200. In the order of sensing, the sensing signal can be controlled as a temperature increasing signal or a temperature reducing signal.

In the same manner, the controller 243 controls the driving unit 140 to drive the push-pull rod 141 according to the temperature sensing signal of the temperature sensor 242, thereby controlling the core ring 152b to adjust the cold water inlet 111 and the The proportion of water entering the hot water inlet 112 to feed the inductive water supply device 200 The temperature can be stabilized at the set temperature, and the detailed temperature control method is as described above, and is not described herein.

Moreover, in another embodiment, the temperature increase signal or the temperature decrease signal may be a temperature segment number control signal. That is to say, the temperature of the feed water of the inductive water supply device 200 can be set by a plurality of temperature segment setting values. For example, it can be set to four temperature segments: cold water, low temperature water, high temperature water and hot water.

The controller 243 controls the driving unit 140 to drive the push-pull rod 141 according to the temperature segment of the cold water, thereby controlling the core ring 152b to adjust the cold water inlet 111 to be fully open and the hot water inlet 112 to be closed. . Alternatively, the controller 243 controls the driving unit 140 to drive the push-pull rod 141 according to the temperature range of the low-temperature water, thereby controlling the core ring 152b to adjust the cold water inlet 111 to open two-thirds and the hot water inlet 112. Turn on one third. Alternatively, the controller 243 controls the driving unit 140 to drive the push-pull rod 141 according to the temperature segment of the high-temperature water, thereby controlling the core ring 152b to adjust the opening of the cold water inlet 111 by one third and the hot water inlet 112. Open two-thirds. Alternatively, the controller 243 controls the driving unit 140 to drive the push-pull rod 141 according to the number of temperature segments of the hot water, thereby controlling the core ring 152b to adjust the cold water inlet 111 to be in a closed state and the hot water inlet 112 to be fully opened. status.

Therefore, the straight pull type water valve of the present invention drives the push-pull rod by the driving unit to directly push and pull the water outlet switch, thereby controlling the water inlet amount of the cold water inlet and the hot water inlet and controlling the straight pull water. Whether the valve supplies water. In addition, the straight pull type water valve can be applied to an inductive water supply device and method, and the water supply device of the direct pull type water valve is controlled by induction, thereby controlling whether the inductive water supply device supplies water, and controlling the straight through the induction method. The feed water temperature of the pull water valve controls the proportion of the cold water inlet and the hot water inlet.
