The middle support 100 is a plate-like structure or other shaped structure with at least a flat top.

The supporting member 110 is disposed above the middle tray 100 and connected to the first top surface 102, and a receiving area 112 is formed between the supporting member 110 and the first top surface 102. The side of the support member 110 facing away from the middle bracket 100 is formed with a second top surface 114, and the second top surface 114 can be provided with other structures such as a cold tank 130.

The cold tank 130 is attached to the second top surface 114, the hot tank 140 is disposed within the containment region 112, and the cold tank 130 and the hot tank 140 are disposed on different sides of the support member 110. Meanwhile, a plurality of water paths are formed in the water path plate 120, and the cold tank 130 and the hot tank 140 are connected to each other through the water paths, so that water can be introduced into and discharged from the cold tank 130 and the hot tank 140.

It is understood that the cold tank 130 is disposed at the second top surface 114, and the supporting member 110 can ensure that there is a height difference between the cold tank 130 and the hot tank 140, so as to ensure that the water in the cold tank 130 has a sufficient water outlet amount under the self-weight effect.

In some embodiments, the height difference between the cold tank 130 and the water outlet of the cold tank 130 is at least 50cm, which can make the water outlet flow of the cold tank 130 reach 1.2L/min.

The middle support 100 and the support 110 form a main frame structure, and the support 110 can determine the position relationship between the cold tank 130 and the hot tank 140, so as to facilitate the modular assembly of the waterway assembly. Meanwhile, the middle support 100 and the support 110 help to increase the volume of the waterway assembly, and more installation positions of components can be reserved.

The cold tank 130 is connected with the hot tank 140 through the water channel plate 120, so that the arrangement of water pipes is reduced, the tightness of the water channel assembly is improved, and the convenience of the assembling process is improved.

According to the waterway assembly provided by the embodiment of the present invention, the supporting member 110 is disposed above the middle support 100 and connected to the first top surface 102, and the accommodating area 112 is formed between the supporting member 110 and the first top surface 102, and the accommodating area 112 can be used for placing components such as the hot tank 140.

In some embodiments, the support member 110 includes a top plate 116 and at least two side plates 118, the side plates 118 being connected to edges of the top plate 116.

It will be appreciated that the top plate 116 and the two side plates 118 form an arcuate structure, the location between the two side plates 118 and the top plate 116 forms the containment region 112, and the hot can 140 and, as will be described below, the compressor 170 are disposed within the containment region 112. The side of the top plate 116 remote from the first top surface 102 forms a second top surface 114, and a cold tank 130 is mounted above the top plate 116.

The support member 110 includes a top plate 116 and a side plate 118, so as to fix the cold tank 130 and the hot tank 140 in a relative position, which is convenient for assembly. 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, first waterway 122, second waterway 124, third waterway 126, and fourth waterway 128 are formed within waterway plate 120. 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 passage 126 has a third water inlet 1262 and a third water outlet 1264, the third water inlet 1262 is communicated with the water outlet of the hot tank 140, and the hot water flows out along the third water outlet 1264. The fourth water path 128 is formed with a fourth water inlet 1282 and a fourth water outlet 1284, the fourth water inlet 1282 is communicated with the water outlet of the cold tank 130, and the cold water flows out along the fourth water outlet 1284.

It should be noted that the cold tank 130 has at least two water outlets, one of which is connected to the second water inlet 1244 for supplying the hot tank 140 with drinking water, and the other of which is connected to the fourth water inlet 1282 for supplying the fourth water path 128 with cold water.

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 drinking water, and that a portion of the drinking water remains in the ice bladder of the cold tank 130 and another portion flows 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 helpful for reducing energy consumption of the waterway assembly. Meanwhile, the first water inlet 1222 and the second water outlet 1242 are adjacently arranged, so that a water supply pipeline of the water path assembly is more simplified, and the modular assembly and the volume reduction are facilitated.

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 anti-cross-temperature water path 158 is a circuitous water path, and the anti-cross-temperature water path 158 forms a U-shaped pipe structure between the first branch 152 and the second branch 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 cross-temperature 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 larger 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 inWith a space meter, Q₁The larger the better, the preferred term is Q₁≥2*Q₂*K。

The anti-cross-over 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 channel, 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 trapway 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 trapway 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 hole or avoid the notch and then are connected to the water circuit board 120, and redundant water supply pipelines do not need to be arranged at the moment.

It can be understood that, in the case that the through hole or the relief notch is formed on the top plate 116, the assembly efficiency between the waterway plate 120, the cold tank 130 and the hot tank 140 is higher, the structure is more compact, and the automatic production of the waterway assembly is facilitated.

In some embodiments, an electronic control box 160 is further disposed on the waterway assembly, and the electronic control box 160 is used for controlling water inlet and outlet and temperature of the waterway assembly. Reserved buckling positions 1166 of the electronic control box 160 are formed on the top plate 116, so that the electronic control box 160 can be assembled, and the reserved buckling positions 1166 of the electronic control box 160 can make full use of the free area on the top plate 116, so that waterway components are more simplified.

In other embodiments, a wire buckle 1182 is disposed on one side of the supporting member 110, and in a case that the electronic control box 160 is mounted on the top plate 116, the flat cable in the electronic control box 160 is inserted into the wire buckle 1182, so that the waterway assembly is more concise by the wire buckle 1182.
