The cold tank 130 and the hot tank 140 are connected through the water channel plate 120, so that the assembly efficiency is high, and the water leakage prevention performance of the water channel assembly is improved.

In some embodiments, waterway plate 120 has formed therein a first waterway 122, a second waterway 124, a third waterway 126, and a fourth waterway 128. The first waterway 122 is formed with a first water inlet 1222 and a first water outlet 1224, and the first water outlet 1224 is communicated with the water inlet of the hot tank 140 for supplementing the water source to the hot tank 140. The second water path 124 is formed with a second water inlet 1244 and a second water outlet 1242, and the second water inlet 1244 is communicated with the water outlet of the cold tank 130 for receiving the drinking water in the cold tank 130. The third water channel 126 has a third water inlet 1262 and a third water outlet 1264, the third water inlet 1262 is connected to the water outlet of the hot water tank 140, and the hot water flows out along the third water outlet 1264.

In some embodiments, the waterway plate 120 further includes other waterways to enable flow and circulation of cold and hot water, etc.

According to the waterway assembly provided by the embodiment of the present invention, the first water outlet 1224 communicates with the water inlet of the hot tank 140, the second water inlet 1244 communicates with the water outlet of the cold tank 130, and the first water inlet 1222 and the second water outlet 1242 are adjacently disposed and connected to the trap 150.

It will be appreciated that the cold tank 130 receives external potable water, with a portion of the potable water remaining in the ice bladder of the cold tank 130 and another portion flowing along the second waterway 124 into the trapway 150. The first water inlet 1222 is connected to the trap 150, and thus supplies drinking water into the hot tank 140. The water trap 150 can prevent the cold tank 130 and the hot tank 140 from being directly connected, thereby preventing heat exchange between the cold tank and the hot tank, and being beneficial to reducing the energy consumption of the waterway assembly. Simultaneously, first water inlet 1222 and second delivery port 1242 are adjacent to be set up, can make water route assembly's water supply line retrench more, help the modularization equipment and reduce the volume.

In some embodiments, the trapway 150 is formed with a first leg 152, a second leg 154, and a third leg 156, the first leg 152, the second leg 154, and the third leg 156 being in communication with one another. The first branch port 152 is communicated with the first water inlet 1222, the second branch port 154 is communicated with the second water outlet 1242, the third branch port 156 is suitable for releasing warm water, and a warm water leakage prevention waterway 158 is formed between the first branch port 152 and the second branch port 154.

It can be understood that in the anti-warm-cross waterway 158, the drinking water is temporarily accumulated, and the heat in the hot tank 140 can be blocked from transferring to the cold tank 130, so that the temperature in the cold tank 130 can be prevented from rising, and the energy consumption of the waterway assembly can be reduced. Meanwhile, at the trap 150, the drinking water receives heat from the inside of the hot tank 140 to form warm water, and the warm water can be released along the third branch port 156, so that more water temperature choices can be provided for the user.

In some embodiments, the temperature cross-over preventing waterway 158 is a circuitous waterway, and the temperature cross-over preventing waterway 158 forms a U-shaped pipe structure between the first branch port 152 and the second branch port 154, and a U-shaped water column is formed in the U-shaped pipe, so that heat transfer between the first water inlet 1222 and the second water inlet 1244 can be avoided, and further, temperature cross-over between the hot tank 140 and the cold tank 130 can be prevented.

The trap 150 is disposed at one side of the top plate 116, so that the waterway assembly can be kept compact without increasing the height of the supporter 110.

According to an embodiment of the present invention, the volume of the trap 150 should be greater than the product of the volume of the hot tank 140 and the coefficient of thermal expansion of water, assuming that the volume of the trap 150 is Q₁The volume of the thermal tank 140 is Q₂The coefficient of expansion of water heating is K. (it is known from physical phenomena that when water is heated to 90 degrees or more, the expansion coefficient of hot water is about 5 to 10%), the capacity Q of the trap 150 is large₁≥Q₂K, of course in the case of a space meter, Q₁The larger the better, the preferred term is Q₁≥2*Q₂*K。

The anti-cross-temperature effect is also related to the shape of the trapway 150, and the trapway 150 can be V-shaped, U-shaped, or other shapes, preferably a vertically disposed U-shaped flow passage, as shown in fig. 25.

When the volume of water in the hot tank 140 is 1L, the volume of water in the trap 150 is 80ml, the temperature of water in the hot tank 140 is 95 °, and the temperature of the inflow water is 25 °, as shown in fig. 23, the trap 150 is in a horizontal state in the pipe at this time (strictly speaking, the trap does not exist at this time), the trap 150 has almost no effect of preventing cross-temperature, and the detected inflow water temperature is 53 °. When the trap 150 is V-shaped, please refer to fig. 24, an included angle between adjacent pipe sections (vertical pipe section and inclined pipe section) in the trap 150 is 45 °, and the detected water inlet temperature is 35 °. When the trapway 150 is shaped like a U, please refer to fig. 25, the inlet water temperature is detected to be 26 °. Therefore, when the trap 150 is U-shaped, the trap 200 has the best effect of preventing the cold water and the hot water from being mixed.

In other embodiments, the anti-warm-cross water path 158 is a water path provided with a check valve, which can prevent heat in the hot tank 140 from being transferred to the cold tank 130.

The water circuit board 120 is connected to the second top surface 114, the cold tank 130 is connected to a side of the water circuit board 120 facing away from the second top surface 114, and the hot tank 140 is connected to a side of the water circuit board 120 facing away from the cold tank 130, thereby realizing modular assembly of the water circuit components.

In the case where the waterway plate 120 is connected to the second top surface 114, the top plate 116 is formed with through holes and escape notches at positions corresponding to the water inlet and outlet of the hot tank 140. Conduits are formed at the water inlet and the water outlet of the hot tank 140, penetrate through the through holes or avoid the gaps and then are connected to the water circuit board 120, and redundant water supply pipelines do not need to be arranged at the moment.

And then through the cooperation between installation breach 2021 and buckle 210, can realize the quick assembly disassembly of back shroud 202. Specifically, the rear cover plate 202 includes a mounting position and a fixing position along the vertical movement direction: in the dismounting position, the mounting notch 2021 is aligned with the buckle 210, and at this time, the rear cover plate 202 can be pushed toward the mounting frame, and on the basis, the rear cover plate 202 is pushed along the height direction of the rear cover plate 202, so that the positions of the rear cover plate 202 and the mounting notch 2021 are staggered, and the rear cover plate 202 can be prevented from exiting through the position of the mounting notch 2021. In the fixed position, the back cover plate 202 and the clip 210 are fixed, thereby fixing the back cover plate 202 to the mounting frame.

According to the embodiment of the utility model, the number of the installation notches 2021 is plural along the height direction of the rear cover plate 202, and the installation notches 2021 are distributed on two sides of the rear cover plate 202. For example, in fig. 18 and 19, six mounting notches 2021 are provided along the height direction of the rear cover 202, six snaps 210 are provided corresponding to the mounting notches 2021, and after the rear cover 202 is mounted to the mounting frame through the six mounting notches 2021, the rear cover 202 is fixed by the six snaps 210, so that the mounting reliability of the rear cover 202 can be ensured. On the basis, a screw can be additionally arranged to further fix the rear cover plate 202.

In one embodiment, the process of removing and installing the rear cover plate 202 is as follows: aligning mounting notches 2021 with catches 210, moving back plate 202 toward the mounting frame moves back plate 202 to the inside of catches 210. On this basis, back cover plate 202 is pushed upward so that back cover plate 202 is caught in catch 210. On the basis, the bottom of the cover plate is fixed by screws, so that the rear cover plate 202 is prevented from shaking and falling off.

In one embodiment, referring to fig. 20, the latch 210 includes a mounting plate 211 and a limiting plate 212 connected to each other, and a slot 213 is formed between the mounting plate 211 and the limiting plate 212. Further, when the back plate 202 moves into the catching groove 213, the mounting plate 211 and the stopper plate 212 may fix the back plate 202. In order to enhance the fixing effect of the slot 213, a rib 2121 is formed on one side of the limiting plate 212 facing the mounting plate 211, and the rib 2121 may be made of plastic with deformation property, so as to ensure the pressing effect of the limiting plate 212 on the rear cover plate 202. The convex rib 2121 may be of a linear structure, and line contact may better control the compression of the back cover plate 202, so as to prevent the back cover plate 202 from loosening.

In one embodiment, the stopper plate 212 is formed with a guide portion 2122 of the back cover plate 202, and the guide portion 2122 extends in the back-and-forth movement direction of the back cover plate 202. That is, in fig. 20, the guide portion 2122 guides the back cover plate 202 in the direction of the arrow to prevent scratching of the back cover plate 202 during attachment and detachment.
