Referring to fig. 1 to 6, the waterway plate of the present invention includes a main body 300 and a base 400, wherein the base 400 is detachably connected to the main body 300. The water pump 100, the water quality detecting switch 200, the flow meter 500 and the temperature sensor 600 are fixedly connected to the main body 300 of the water path plate.

The front surface of the main body 300 includes a heating unit mounting position for connecting a heating unit (not shown); the heating component can be a heating pipe, and in one embodiment, the heating component comprises 3 parallel heating pipes which are arranged in a centrosymmetric manner and are inserted into the heating component mounting position through a connecting piece. In one embodiment, the heating element installation site has a first water inlet hole 311, a second water inlet hole 312 and a third water inlet hole 313, which are respectively connected to the first heating tube, the second heating tube and the third heating tube, wherein, on the back of the main body 300, the second water inlet hole 312 is communicated with the third water inlet hole 313, and the first water inlet hole 311 is not communicated with the second water inlet hole 312 and the third water inlet hole 313, so that 3 heating tubes are sequentially connected (connected in series) end to end, water sequentially flows through each heating tube, and after entering the first heating tube from the first water inlet hole 311, water flows out from the other end of the third heating tube; in other embodiments, as long as the heating pipes are connected in series, if the number of the heating pipes is not 3, the heating pipes may be similarly arranged, except that when the number of the heating pipes is even, for example, 4, the heating component mounting position has three water inlets and one water outlet, the water outlet is communicated with an external waterway, both the water before heating and the water after heating flow through the waterway plate body 300, and when the number of the heating pipes is odd, for example, 3 or 5, the heating component mounting position only has the same number of water inlets (3 or 5) as the heating pipes, without arranging the water outlet, and at this time, the water after heating does not flow through the waterway plate body 300.

The main body 300 further comprises a water pump mounting position 320 for mounting the water pump 100, a water pump inlet hole 322 and a water pump outlet hole 321 which penetrate through the main body 300 are arranged in the water pump mounting position 320, external water enters the water pump 100 through the water pump inlet hole 322, and the water pump 100 pumps the water into the water pump outlet hole 321. The main body 300 further includes a water quality detection switch mounting location 330 for mounting the water quality detection switch 200; the main body 300 further includes a temperature sensor mounting location 340 for mounting the temperature sensor 600.

The back of the main body 300 is provided with a first flow passage 301 for receiving external water, in one embodiment, the first flow passage 301 is provided with a water inlet 350 penetrating through the main body 300, the external water enters the first flow passage 301 through the water inlet 350 and flows into the water pump inlet hole 322 through the first flow passage 301, and at this time, the external water enters from the front of the main body 300; if the external water directly enters the water pump through the water inlet hole 322, the first flow passage 301 is not required to be provided, and the external water directly enters from the back of the main body 300.

The back of the main body 300 is also provided with a second flow channel 302, a water outlet 321 of the water pump is communicated with the second flow channel 302, water flows into the second flow channel 302 from the water outlet 321 of the water pump, a one-way valve 700 is installed in the second flow channel 302 to prevent the water from flowing backwards, and the second flow channel 302 is divided into a front section and a rear section by the one-way valve 700; a detection hole 331 is further formed in the second flow channel, the detection hole 331 penetrates through the main body 300 and is located below the water quality detection switch installation position 330, and a probe of the water quality detection switch 200 extends into the second flow channel 302 from the detection hole 331 and is used for detecting water temperature to control on-off.

The back of the main body 300 is further provided with a sixth flow passage 306 and a seventh flow passage 307, and a flow meter 500 communicating the second flow passage 302 with the sixth flow passage 306, a flow meter first mounting position 304 for mounting the flow meter 500 communicates with the sixth flow passage 306, a flow meter second mounting position 305 for mounting the flow meter 500 communicates with the second flow passage 302, the sixth flow passage 306 is used for introducing water passing through the flow meter 500 into the first water inlet hole 311, and the second water inlet hole 312 and the third water inlet hole 313 communicate in the seventh flow passage 307. In other embodiments, if there are 4 heating pipes, the back surface of the main body 300 further has water outlet holes penetrating through the main body 300, and if there are 5 heating pipes connected in series, the number of the seventh flow passages 307 on the back surface of the main body 300 can be increased as required. In other embodiments, if the heating pipes are not connected in series but connected in parallel, the first water inlet 311 may serve as a general water supply hole for the heating module, and water is simultaneously supplied to a plurality of heating pipes by matching with the parallel connection mechanism of the heating pipes, so that other water inlets are not needed, and the seventh flow channel 307 is omitted; in fact, the prior art has almost abandoned the parallel heating tube structure, and since the heating tubes connected in series can implement heating with a longer length, the heating effect is better, so that the seventh flow channel 307 is almost a necessary solution in this case at present; the exception is that, for example, only the water inlet and the water outlet connected to the heating element are disposed in the water channel plate, and the seventh flow channel 307 is disposed inside the heating element, which can achieve almost the same effect, but the seventh flow channel 307 is integrated in the water channel plate, which can save a part of the volume of the external flow channel, and is beneficial to reducing the volume of the whole water channel system, so that the seventh flow channel 307 is external, which is not an optimal solution.

The first flow channel 301, the second flow channel 302 and the sixth flow channel 306 are connected end to form a flow channel whole, and water flows through the first flow channel 301, the second flow channel 302 and the sixth flow channel 306 in sequence; when the seventh flow channel 307 exists, the seventh flow channel 307 is also connected in series with the whole flow channel, and at this time, water flows through the first flow channel 301, the second flow channel 302, the sixth flow channel 306 and the seventh flow channel 307 in sequence.

Since the installation positions (the heating assembly installation position, the water pump installation position 320, the water quality detection switch installation position 330, the temperature sensor installation position 340, and the like) are all in direct contact with the water flow, the installation positions are communicated with the flow channel, that is, the installation position on the front surface of the main body 300 penetrates through the main body 300 and penetrates through the flow channel.

The base 400 includes a first sealing portion 401, a second sealing portion 402, a third sealing portion 403, a sixth sealing portion 406, and a sixth sealing portion 407, the first sealing portion 401 is configured to vertically close the first flow passage 301, the second sealing portion 402 and the third sealing portion 403 are configured to vertically close two front and rear sections of the check valve 700 in the second flow passage 302, and the sixth sealing portion 406 and the seventh sealing portion 407 are respectively configured to vertically close the sixth flow passage 306 and the seventh flow passage 407. The vertical direction of the present invention is perpendicular to the plane of the main body 300 and the base 400.

The base 400 also includes a third mounting location 404 that mates with the first flowmeter mounting location 304 and a fourth mounting location 405 that mates with the second flowmeter mounting location 305, respectively securing the ends of the flowmeter 500. In the present embodiment, when the flowmeter 500 is located inside the flow channel, the mounting position of the flowmeter 500 is also located inside the flow channel. In other embodiments, when the flow meter 500 cannot be installed in the flow passage, a corresponding flow meter installation site may be provided on the front surface of the main body 300 in a manner similar to the water pump installation site 320 and the water quality detection switch installation site 330.

The utility model discloses an among the water route board, rivers get into from water route board one end to basically, the inboard round postheating that flows in proper order along the periphery in water route gets into next subassembly, if be the coffee machine, then the water after the heating gets into to dash and steep or make the subassembly, if be the water dispenser, then the water after the heating gets into hot water play water subassembly, like hydrothermal tap. The arrangement mode of the embodiment enables water flow to uniformly flow through the water channel plate, and the water channel plate is free of sharp turns (such as 180-degree rotation), crossed or branched water channels, so that the defect of mutual influence among the water channels is fundamentally avoided, and meanwhile, the structure is very simple. If a certain device (measurement and control device for short) with detection and/or control functions is not needed, such as the flowmeter 500 or the one-way valve 700, the installation position of the device is directly removed from the corresponding flow channel, and the flow channels separated by the original measurement and control device are communicated; if the water quality detecting switch 200 is not required, the installation position of the apparatus may be removed directly from the front surface of the main body 300. If a certain measurement and control device needs to be added, only the installation position needs to be arranged on the front face of the corresponding flow channel or the main body 300, the application of other devices cannot be influenced, and the device is very suitable for meeting various different waterway function requirements. When more devices need to be arranged, the water paths of the water path board can be arranged in a mode similar to spiral threads, so that the limited surface and space of the water path board can be better applied, and the volume of the electrical equipment applying the water path board is smaller.

In addition, when the water pump, the heating assembly and other devices can be smaller in size, the corresponding mounting positions can even be positioned inside the main body 300; alternatively, in addition to the conventional devices, the thickness and the like of the waterway plate may be increased, and these devices may be directly mounted inside the waterway plate. However, the cost of manufacturing such a circuit board may increase and the sealing requirements increase, and therefore, the presently preferred embodiment still places these devices on the outside of the circuit board.
