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.

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 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.

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.

It should be noted that the trap 150 is disposed at one side of the first support plate 116, and the water path assembly can be kept compact without increasing the height of the support member 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 water route 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 water route of intaking (being first water route 122 and second water route 124), can avoid appearing the phenomenon of getting warm suddenly.

Assuming that the volume of the trap 150 is Q1, the volume of the hot tank 140 is Q2, the expansion coefficient after water heating 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 to 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 a state where the waterway plate 120 is coupled to the second top surface 114, the first support plate 116 is formed with through holes 1162 and escape notches 1164 at positions corresponding to the water 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 first support 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 first supporting plate 116, so that the electronic control box 160 can be assembled, and the reserved buckling position 1166 of the electronic control box can make full use of the free area on the first supporting plate 116, so that the waterway assembly is more simplified.

In other embodiments, a wire buckle 1182 is disposed at one side of the supporting member 110, and when the electronic control box 160 is mounted on the first supporting plate 116, a 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 location of the electrical control box 160, so that the cables connected to the electrical control box 160 can be collectively arranged, thereby avoiding messy cables 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 support member 110 has a total height H1 and the heat tank has a height H2, and the ratio of H1 to H2 is between 1-5 in the vertical direction.

It will be appreciated that the support 110 forms a main frame of the waterway assembly, and standardized production and assembly of products can be achieved when the height of the main frame is determined.

In some embodiments, the length of the partition plate 100 is L1, the length of the support 110 is L2, and the ratio of L1 to L2 is 1-5 in the transverse direction.

It can be understood that the main frame of the waterway assembly is fixedly formed by the second supporting plate 118 of the support 110 and both sides of the partition plate 100, and the overall length of the first supporting plate 116 is smaller than the length of the partition plate 100 in order to facilitate the automatic assembly of the partition plate 100 and the second supporting plate 118 and avoid interference during assembly. Meanwhile, a containing area 112 for placing the hot pot 140 is formed below the first support plate 116, and the overall length of the first support plate 116 also meets the size requirement of the containing area 112, so that the ratio of L1 to L2 is 1-5.

In some embodiments, the partition plate has a width W1, the two second support 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 1-10, and the ratio of W2 to W3 is 1-5.

It will be appreciated that the cold tank 130 is connected to a second water inlet 1244 for replenishing the hot tank 140 with drinking water. The cold tank 130 is also connected to a fourth water inlet 1282 for discharging cold water from the cold tank 130 for use by a user. The hot tank 140 is connected to the third water inlet 1262 of the water channel plate 120 for discharging the hot water in the hot tank 140 for the user to use. The hot tank 140 is also connected to a first water outlet 1224 on the circuit board 120 for receiving external drinking water.

In order to improve the strength of the overall module of the waterway assembly and to achieve the connection between the cold tank 130 and the hot tank 140, the partition plate 100 needs to cover the hole locations of the water inlet and the water outlet, thereby improving the connection strength of the overall module of the waterway assembly.

The temperature cross-preventing waterway is a waterway which is arranged in a roundabout manner from top to bottom, and the first supporting plate 116 needs to avoid the structure. Meanwhile, in order to reduce the cost and avoid unnecessary material waste, the width of one side of the first support plate 116 is smaller. Therefore, the ratio of W1 to W2 is between 1 and 10, and the ratio of W2 to W3 is between 1 and 5.

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 connected to 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.

When the trap 150 is formed with the first branch port 152, the second branch port 154, and the third branch port 156, the first branch port 152, the second branch port 154, and the third branch port 156 communicate with each other. 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. In the anti-heat leakage waterway 158, the drinking water is temporarily accumulated, so that the heat in the hot tank 140 can be prevented from being transferred to the cold tank 130, the temperature in the cold tank 130 can be prevented from being increased, and the energy consumption of the waterway assembly is further 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.

Under the condition that the temperature cross-over preventing waterway 158 is a waterway which is arranged in a vertically roundabout manner, 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 can be prevented from being transferred between the first water inlet 1222 and the second water inlet 1244, and further, the temperature cross-over between the hot tank 140 and the cold tank 130 can be prevented. It should be noted that the trap 150 is disposed at one side of the first support plate 116, and the water path assembly can be kept compact without increasing the height of the support member 110.

In the case where the warm water leakage preventing path 158 is a water path provided with a check valve, the check valve can prevent heat in the hot tank 140 from being transferred to the cold tank 130.

In the case where waterway plate 120 is coupled to second top surface 114, first support plate 116 is formed with through-holes 1162 or escape notches 1164 at positions corresponding to the water inlet and outlet of hot pot 140. Conduits are formed at the water inlet and the water outlet of the hot pot 140, penetrate through the through hole 1162 or avoid the position of the notch 1164, and then are connected to the water circuit board 120. The assembly efficiency among 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.

Under the condition that the waterway assembly is further provided with the electric control box 160, the electric control box 160 is used for controlling the water inlet and outlet and the temperature of the waterway assembly. The reserved buckling position 1166 of the electronic control box is formed on the first supporting plate 116, so that the electronic control box 160 can be assembled, and the reserved buckling position 1166 of the electronic control box can make full use of the free area on the first supporting plate 116, so that the waterway assembly is more simplified.
