In addition, technical solutions between various embodiments may be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination should not be considered to exist, and is not within the protection scope of the present invention.

Referring to fig. 1 to 4, in an embodiment of the integrated water inlet and outlet device 200 of the present invention, the integrated water inlet and outlet device 200 includes a base 300, a thermostatic valve 700, and a control module 900. Referring to fig. 4 and 5, the base 300 is constructed with a water inlet connection pipe 310 for an external water supply line connection, and a water outlet connection pipe 320 for an external water line connection; the base 300 is further configured with an inlet flow passage 518 and an outlet flow passage 410, the inlet flow passage 518 is adapted to communicate the inlet nipple 310 with the inner container 110 to supply cold water to the inner container 110, and the outlet flow passage 410 is adapted to communicate the outlet nipple 320 with the inner container 110 to output hot water of the inner container 110. The thermostatic valve 700 is installed on the base 300, and the thermostatic valve 700 is adapted to mix the hot water of the outlet flow passage 410 and the cold water supplied from the inlet connection pipe 310 into thermostatic water and output the thermostatic water from the outlet connection pipe 320. The control module 900 is coupled to the thermostatic valve 700 to control operation of the thermostatic valve 700.

Specifically, the integrated water inlet and outlet device 200 may be disposed in an inverted T shape, an L shape or a 1-shape (as shown in fig. 22-a to 22-C) in appearance. The outer end of the water inlet connection pipe 310 of the integrated water inlet and outlet device 200 is used for connecting an external water supply pipeline and is used as a cold water flow passage for supplying cold water to the inner container 110; the outer end of the outlet pipe 320 of the integrated water inlet and outlet device 200 is used for connecting an external water pipeline and serving as a hot water flow passage for supplying constant temperature water to users. The external water pipeline can be a bathing water pipeline, a drinking water pipeline, a kitchen water pipeline and other user-used terminals. The external water supply line or the external water supply line may be installed downward, may be installed hidden toward the rear, and may be installed left and right.

Here, the integrated water inlet and outlet device 200 integrates the water inlet connection pipe 310, the water outlet connection pipe 320, the water inlet channel 518 and the water outlet channel 410, so that the water inlet function and the water outlet function can be realized simultaneously only by integrally installing the integrated water inlet and outlet device 200 in a mounting port of the inner container 110, and thus two mounting ports for respectively communicating an external water supply pipeline and mounting an external water pipeline are not required to be preset on the inner container 110, the number of the mounting ports is reduced, and further mounting processes (such as welding and other processing processes) for installing the integrated water inlet and outlet device 200 on the inner container 110 are reduced, and the risk of water leakage caused by poor mounting is reduced. As such, the thermostatic valve 700 is integrated into the integrated water inlet and outlet device 200, thereby eliminating the need for a user to separately assemble a mixing valve, reducing installation operations for the user, and further reducing the risk of poor installation.

When the integrated water inlet and outlet device 200 is in operation, the cold water from the external water supply line enters from the water inlet connection pipe 310 of the integrated water inlet and outlet device 200 and then is divided into two paths of cold water, wherein one path of cold water enters the inner container 110 from the water inlet flow passage 518 of the integrated water inlet and outlet device 200, so as to supply water to the inner container 110, and the water is heated in the inner container 110; one of the cold water flows into the thermostatic valve 700. Meanwhile, the hot water in the inner container 110 is pushed by the newly entered water, and then the hot water enters the thermostatic valve 700 through the water outlet flow path of the integrated water inlet and outlet device 200, and is further mixed with the cold water in the thermostatic valve 700 to form thermostatic water with a preset water outlet temperature, and the thermostatic water is output to the external water pipeline through the water outlet connection pipe 320, and is output to the user through the external water pipeline. In the process, the thermostatic valve 700 is controlled and adjusted by the control module 900, so that the opening of the thermostatic valve 700 is timely adjusted, the proportion of the mixed hot water and the cold water is further adjusted, and the integrated water inlet and outlet device 200 is ensured to output the thermostatic water according to the preset outlet water temperature. The preset outlet water temperature can be set by the user or pre-stored in the integrated water inlet and outlet device 200. The constant temperature water is mixed water with the temperature between that of hot water and that of cold water.

According to the technical scheme of the invention, the thermostatic valve 700 is arranged on the base 300 of the integrated water inlet and outlet device 200, and the thermostatic valve 700 is connected with the control module 900, so that the thermostatic valve 700 is controlled by the control module 900 to automatically mix hot water in the water outlet flow channel 410 of the integrated water inlet and outlet device 200 with cold water supplied by the water inlet connecting pipe 310 to form thermostatic water with preset water outlet temperature, and then the thermostatic water is output from the water outlet connecting pipe 320, so that the thermostatic water outlet is automatically regulated without manual regulation of a user. In addition, the integrated water inlet and outlet device 200 integrates the water inlet connection pipe 310, the water outlet connection pipe 320, the water inlet channel 518, the water outlet channel 410 and the thermostatic valve 700, so that only one mounting opening for mounting the integrated water inlet and outlet device 200 needs to be formed in the inner container 110, thereby reducing the mounting procedures and reducing the risk of poor mounting.

Referring to fig. 4 and 5, in an embodiment, the integrated water inlet and outlet device 200 further includes a water outlet pipe 400 and a water inlet module 500 disposed on the base 300. Wherein, the water outlet end of the water outlet pipe 400 is fixed on the base 300, and the water outlet pipe 400 is suitable for forming the water outlet channel 410 of the base 300; the water inlet module 500 is inserted into the water outlet end of the water outlet pipe 400 and is fixedly connected with the base 300, and the water inlet module 500 is suitable for forming the water inlet channel 518 of the base 300. When assembling the integrated water inlet and outlet device 200, the water inlet module 500 may be firstly fixed to the end of the water outlet pipe 400 far away from the water inlet hole 420, and then the water inlet module 500 is fixed to the base 300, so that the water outlet pipe 400 is connected and fixed with the base 300 along with the water inlet module 500.

In order to improve the anti-leakage function of the integrated water inlet and outlet device 200, one or more of the base 300, the water inlet module 500 and the water outlet pipe 400 of the integrated water inlet and outlet device 200 are usually made of plastic material, so as to improve the insulating property of the integrated water inlet and outlet device 200, and further enhance the anti-leakage function of the integrated water inlet and outlet device 200. However, if the base 300 is made of a plastic material, the thermostatic valve 700 may be worn away from the inside of the base 300 while the opening degree of the thermostatic valve is repeatedly adjusted in the inside of the base 300.

Referring to fig. 8 to 10, in view of the above, the integrated water inlet and outlet device 200 further includes a flow guiding insert 370 embedded in the base 300, wherein the flow guiding insert 370 is configured with a valve cavity 371, a first inlet 372, a second inlet 373, a first outlet 374 and a second outlet 375; the first inlet 372 is communicated with the water outlet end of the water inlet connecting pipe 310, the second inlet 373 is communicated with the water outlet end of the water outlet pipe 400, the first outlet 374 is communicated with the water inlet end of the water outlet connecting pipe 320, and the second outlet 375 is communicated with the water inlet end of the water inlet flow passage. The thermostatic valve 700 is mounted to the valve cavity 371 of the flow-directing insert 370, and the thermostatic valve 700 is rotatable relative to the flow-directing insert 370 to adjust its degree of opening in communication with the first inlet 372 and/or the second inlet 373.

Specifically, the base 300 has a fitting cavity 340 therein, and the flow guide insert 370 is fitted in the fitting cavity 340. The flow directing insert 370 is preferably made of a stronger material such as a metal (copper or aluminum or alloys). Because the flow guiding insert 370 is embedded in the base 300, the flow guiding insert 370 is not easy to conduct electricity leakage outwards. Therefore, by selectively mounting the thermostatic valve 700 to the valve cavity 371 of the flow guide insert 370, the thermostatic valve 700 does not contact the inside of the susceptor 300, so that the abrasion of the thermostatic valve 700 to the susceptor 300 can be reduced.

Since the thermostatic valve 700 is rotatable relative to the flow-guiding insert 370, so as to drive the thermostatic valve 700 to rotate, the opening degree of the communication between the thermostatic valve 700 and the first inlet 372 and/or the second inlet 373, that is, the ratio of the cold water input into the thermostatic valve 700 from the first inlet 372 to the hot water input into the thermostatic valve 700 from the second inlet 373, is adjusted, and thus the temperature of the thermostatic water output from the thermostatic valve 700 to the water outlet connection pipe 320 is adjusted.

Referring to fig. 9 to 11, in an embodiment, the thermostatic valve 700 includes a valve core 710 and a valve stem 720 configured at one end of the valve core 710 and connected to a control module 900; the valve core 710 is inserted into the valve cavity 371 of the flow guiding insert 370, the valve core 710 is configured with a water inlet 711 and a water outlet 712, and the opening degree of the thermostatic valve 700, which is communicated with the first inlet 372 and/or the second inlet 373, can be adjusted by rotating the valve core 711.

In particular, the outlet 712 of the thermostatic valve 700 extends along the circumference of the cartridge 710 such that the outlet 712 has a greater length along the circumference of the cartridge 710 to ensure that the outlet 712 remains in communication with the first outlet 374 of the flow directing insert 370 during rotation of the thermostatic valve 700. The valve stem 720 of the thermostatic valve 700 is provided with a sealing ring 102 for sealing a gap between the circumference of the valve stem 720 and the inner wall of the valve cavity 371 of the flow-guiding insert 370 to prevent water from leaking out of the gap. The thermostat valve 700 rotates to move the water inlet 711 of the valve core 710 between the first inlet 372 and the second inlet 373, so as to adjust the opening degree of the water inlet 711 communicated with the first inlet 372 and/or the second inlet 373, thereby enabling the integrated water inlet and outlet device 200 to have multiple operation modes.

The various modes of operation of the integrated water inlet and outlet device 200 are described herein as follows:

1) a full hot water mode: when the thermostatic valve 700 rotates forward (clockwise or counterclockwise) to a first opening degree, the thermostatic valve 700 seals off the first inlet 372 of the flow guide insert 370, the water inlet 711 of the thermostatic valve 700 is only communicated with the second inlet 373 of the flow guide insert 370, and all cold water supplied by the external water supply pipeline sequentially enters the inner container 110 through the water inlet connecting pipe 310 and the water inlet module 500 for heating; the hot water in the inner container 110 enters the thermostatic valve 700 from the water outlet pipe 400, the second inlet 373 of the flow guide insert 370, and the water inlet 711 of the thermostatic valve 700, and is then output from the thermostatic valve 700 through the water outlet 712 of the thermostatic valve 700 to the water outlet connection pipe 320, and finally is delivered to the external water pipeline through the water outlet connection pipe 320, thereby realizing the function of full hot water.

2) Constant temperature water regulation mode: when the thermostatic valve 700 rotates forward to a second opening degree, the thermostatic valve 700 gradually opens the first inlet 372 of the flow-guiding insert 370 and gradually closes the second inlet 373 of the flow-guiding insert 370, a part of cold water supplied by the external water supply line flows into the thermostatic valve 700 through the first inlet 372 of the flow-guiding insert 370, and the other part of cold water enters the inner container 110 through the water inlet connecting pipe 310 and the water inlet module 500 for heating; and the hot water in the inner container 110 enters the thermostatic valve 700 from the water outlet pipe 400, the second inlet 373 of the flow guide insert 370 and the water inlet 711 of the thermostatic valve 700, and then is mixed with the cold water in the thermostatic valve 700, so that the thermostatic water adjusting function is realized. When the angle of rotation of the thermostatic valve 700 corresponding to the second opening degree is smaller, the amount of hot water entering is larger, the amount of cold water is smaller, and the temperature of mixed water is higher; otherwise, the amount of hot water entering is small, the amount of cold water is large, and the temperature of the warm water is low. The temperature adjusting function is realized by adjusting the rotation angle of the micro-adjustment thermostat valve 700.

3) Full cold water mode: when the thermostatic valve 700 rotates forward to a third opening degree, the thermostatic valve 700 seals the second inlet 373 of the flow guide insert 370, the water inlet 711 of the thermostatic valve 700 is only communicated with the first inlet 372 of the flow guide insert 370, all cold water supplied by the external water supply pipeline flows into the thermostatic valve 700 through the first inlet 372 of the flow guide insert 370 and the water inlet 711 of the thermostatic valve 700, and then the cold water is output from the thermostatic valve 700 through the water outlet 712 of the thermostatic valve 700 to the water outlet connecting pipe 320, and finally the cold water is delivered to the external water pipeline through the water outlet connecting pipe 320, so that the function of full cold water is realized.

4) And (3) adjusting the total cold water quantity: when the thermostatic valve 700 rotates forward to the fourth opening degree, because the thermostatic valve 700 blocks the second inlet 373 of the flow guide insert 370, as the angle of rotation of the thermostatic valve 700 increases, the thermostatic valve 700 gradually closes the first inlet 372 of the flow guide insert 370, so that the flow rate of cold water entering the thermostatic valve 700 is reduced, and further, the function of adjusting the amount of the full-cold water is realized.

5) A full-off mode: when the thermostatic valve 700 rotates forward to a fifth opening degree, the thermostatic valve 700 seals off the first inlet 372 and the second inlet 373 of the flow-guiding insert 370, so that a full-closing function is realized.

In the above-described various operation modes, the first to fifth opening degrees correspond to different angles through which the thermostat valve 700 rotates, respectively.

Referring to fig. 8 and 9, fig. 11 and 12, in an embodiment, to facilitate fixing the thermostatic valve 700, optionally, the integrated water inlet and outlet device 200 further includes a fixing frame 800, the fixing frame 800 is disposed at the opening of the engaging cavity 340 and is connected and fixed with the base 300, and a protruding hole 810 for the valve rod 720 of the thermostatic valve 700 to pass through is formed through the fixing frame 800. The fixing frame 800 is fixed to the base 300 by a plurality of screws to enhance the stability of the connection of the fixing frame 800 with the base 300, so that the fixing frame 800 stably supports the valve stem 720 of the thermostatic valve 700

Referring to fig. 6 and 7, fig. 11 and 12, in order to avoid the rotation transition of the thermostatic valve 700, optionally, a first limit pin 721 is protruded laterally from a portion of the valve stem 720 located inside the fixing frame 800; the inner side surface of the fixing frame 800 is provided with a first stopping portion 820 protruding inwards, and the first stopping portion 820 is suitable for the first limiting pin 721 to support and brake the thermostatic valve 700 when reaching the minimum opening.

Specifically, the base 300 is configured with a limit recess 350 at the open periphery of the fitting chamber 340, and the first limit pin of the stem 720 is located in the limit recess 350. The fixing bracket 800 is formed with a punched hole at a side protruding out of the hole 810, and a punched flange is formed at an inner side surface of the punched hole, and the punched flange forms the first stopper 820. When the thermostat valve 700 reversely rotates to the initial position, the first stopper 820 of the fixing bracket 800 blocks the first stopper 721 of the thermostat valve 700, and the thermostat valve 700 cannot continuously reversely rotate, thereby being restricted to the initial position.

Further, a second limit pin 722 is convexly arranged on the part of the valve rod 720, which is located outside the fixing frame 800, in a lateral direction, and the second limit pin 722 and the first limit pin 721 are arranged in a staggered manner; the inner side surface of the fixing frame 800 is provided with a second stopping portion 830 in an outward protruding manner, and the second stopping portion 830 is suitable for the second limiting pin 722 to abut against and brake the thermostatic valve 700 when the maximum opening degree is reached.

Specifically, the fixing frame 800 is further configured with a punched hole on the other side of the protruding hole 810, and a punched flange is formed on the inner side surface of the punched hole, and the punched flange forms the second stopping portion 830. When the thermostatic valve 700 is rotated forward to the maximum opening degree (e.g., the maximum value of the fifth opening degree), the second stopper 830 of the fixing bracket 800 blocks the second stopper 722 of the thermostatic valve 700, and the thermostatic valve 700 cannot rotate forward, thereby limiting the operation of the thermostatic valve 700 within the current opening degree. It follows that the two stops cooperate to define the angular range of rotation of the thermostatic valve 700, that is to say the opening of the thermostatic valve 700.

When in use, the user can input the preset outlet water temperature through the input unit of the operation module 101; the main control panel 940 receives the preset outlet water temperature input by the input unit, the current inlet water temperature fed back by the first detector 920 and the current outlet water temperature fed back by the second detector 930, and then calculates and judges; wherein:

if the current effluent temperature is lower than the preset effluent temperature, that is, the current effluent temperature is relatively low, at this time, the main control board 940 controls the stepping motor 910 to open and drive the thermostatic valve 700 to increase the opening degree of the second inlet 373 of the flow guide insert 370 and decrease the opening degree of the first inlet 372 of the flow guide insert 370 to increase the hot water amount and decrease the cold water amount, so that the current effluent temperature gradually and stably rises to the preset effluent temperature;

if the current outlet water temperature is higher than the preset outlet water temperature, that is, the current outlet water temperature is higher, at this time, the main control board 940 controls the stepping motor 910 to drive the thermostatic valve 700 to increase the opening degree of the first inlet 372 of the flow guide insert 370 and decrease the opening degree of the second inlet 373 of the flow guide insert 370, so as to increase the cold water amount and decrease the hot water amount, and thus, the current outlet water temperature gradually and stably drops to the preset outlet water temperature.

Specifically, the channel inlet 518a of the inlet channel 518 communicates with the inlet connector 310, and the channel outlet of the inlet channel 518 communicates with the outlet assembly 502. The number of flow chambers 514 may be two or more, such as 2 to 9.
