For convenience of description of the technical solution, in this embodiment, it is defined that the vertical direction is a direction from the bottom to the top of the waterway assembly, the horizontal direction is a direction from the left side to the right side of the waterway assembly, and the longitudinal direction is a direction from the front side to the rear side of the waterway assembly.

The middle bracket 100 is formed with a first top surface 102. The first top surface 102 is relatively flat or has a mounting location for securing a heat sink 140 or the like. 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 by 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, and can fix the relative positions of the cold tank 130 and the hot tank 140, 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 drinking water to the hot tank 140, and the other of which is connected to the fourth water inlet 1282 for supplying cold water to the fourth water path 128.

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. 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-leakage waterway 158, the drinking water temporarily accumulates to block the heat in the hot tank 140 from transferring to the cold tank 130, so as to avoid the temperature rise in the cold tank 130, and further reduce the energy consumption of the waterway assembly. 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 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 outlet 1242 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.

The necessity of the design of the trapway 150, the working principle, and the angular setting are described in detail below:

necessity of design of trap 150: 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. When the temperature of the water in the hot tank 140 rises, the volume of the hot water expands, and when the temperature of the water is heated to be higher than 90 ℃, the expansion coefficient of the hot water is between 5% and 10%. Therefore, when the hot tank 140 is filled with water, the heated and expanded hot water flows back along the first waterway 122, so that the water temperature in the first waterway 122, the second waterway 124 and the cold tank 130 is increased, that is, the temperature cross phenomenon occurs, the use experience of the user is seriously affected, and unnecessary energy consumption is increased.

The principle of operation of the trapway 150: set up the trap 150 that has certain volume on hot pot 140's the waterway of intaking, after the hot water intensification inflation, the expanded part can get into to store temporarily in the trap 150, and hot water can not flow backwards to cold pot 130 along hot pot 140's the waterway of intaking, can avoid appearing the string temperature phenomenon.

Assuming that the volume of the trap 150 is Q1, the volume of the hot tank 140 is Q2, the expansion coefficient after heating water is K, and the expansion coefficient K is between 5% and 10% when the temperature of water is heated to 90 degrees celsius or higher. When the water in the hot tank 140 is heated and heated, the following relationship needs to be satisfied in order to avoid backflow of hot water:

Q1≥K*Q2

in the case of sufficient space, the capacity Q1 of the trapway 150 can be larger, preferably:

Q1≥2*K*Q2

that is, the trapway 150 reserves 2 times the expansion capacity.

Angular setting of the trapway 150: the test was conducted under the conditions that the capacity of the hot tank 140 was 1000ml, the capacity of the temperature cross prevention water path 158 was 80ml, and the temperature of the inlet water was 25 degrees celsius, and the following results were obtained:

in the first situation, referring to fig. 10, the temperature cross-over preventing water path 158 is horizontally connected to the water inlet path of the hot tank 140, i.e. there is no temperature cross-over preventing structure, and the temperature of the water inlet in the second water path 124 can reach 53 ℃, which causes a serious temperature cross-over phenomenon.

In the second situation, referring to fig. 11, the temperature cross-over preventing waterway 158 is communicated with the water inlet waterway of the hot tank 140 at 45 °, that is, the temperature cross-over preventing waterway 158 is disposed obliquely, and the temperature of the water inlet in the second waterway 124 can reach 35 ℃.

In a third situation, referring to fig. 12, the anti-cross temperature waterway 158 is connected to the water inlet waterway of the hot tank 140 at 90 °, that is, when the anti-cross temperature waterway 158 is a U-shaped waterway, the water inlet temperature in the second waterway 124 is 26 ℃, and compared with the initial water inlet temperature of 25 ℃, the cross temperature phenomenon does not occur substantially, so the U-shaped anti-cross temperature waterway having a vertical structure is preferred.

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 a through hole 1162 and an escape notch 1164 at positions corresponding to the inlet and outlet of the hot pot 140. Conduits are formed at the water inlet and the water outlet of the hot pot 140, and the conduits are inserted into the through hole 1162 or the avoiding notch 1164 and then connected to the water circuit board 120, so that an unnecessary water supply pipeline is not required.

It can be understood that, in the case that the through hole 1162 or the relief notch 1164 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. The reserved buckling position 1166 of the electronic control box is formed on the top plate 116, so that the electronic control box 160 can be assembled, the reserved buckling position 1166 of the electronic control box can make full use of the free area on the top plate 116, and the waterway assembly can be 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.

It can be understood that the cable fastener 1182 is disposed near the position of the electronic control box 160, so that the cables connected to the electronic control box 160 can be intensively arranged, thereby preventing the cables from being messy and facilitating the modular assembly of the waterway assembly.

The support member 110 is used to maintain the relative position relationship between the cold tank 130 and the hot tank 140, and ensure the water yield of the cold tank 130. The cold tank 130 and the hot tank 140 are connected by the waterway plate 120, and a pin or a leg may be disposed under the hot tank 140 to ensure the communication between the hot tank 140 and the waterway plate 120.

In some embodiments, the total height of the support member 110 and the middle support 100 in the vertical direction is H1, the height of the hot tank is H2, and the ratio of H1 to H2 is between 1 and 5.

It can be understood that the support 110 and the middle bracket 100 form a main frame of the waterway assembly, and when the height of the main frame is determined, standardized production and assembly of the product can be realized.

In some embodiments, the length of the middle support is L1, the length of the support member is L2, and the ratio of L1 to L2 is between 1 and 5.

It can be understood that the main frame of the waterway assembly is fixedly formed by the side plate 118 of the support 110 and the two sides of the middle support 100, so as to facilitate the automatic assembly of the middle support 100 and the side plate 118 and avoid interference during assembly, and the overall length of the support 110 is smaller than that of the middle support 100. Meanwhile, a containing area 112 for placing the hot pot 140 is formed below the supporting member 110, and the overall length of the supporting member 110 also meets the size requirement of the containing area 112, so that the ratio of L1 to L2 is between 1 and 5.

In some embodiments, the width of the middle bracket is W1, the two side plates 118 include a first side plate and a second side plate which are oppositely arranged, the width of the first side plate is W2, the width of the second side plate is W3, the ratio of W1 to W2 is between 1 and 10, and the ratio of W2 to W3 is between 1 and 5.
