Description

Technical Field

[0001] The utility model relates to the technical field of the water circuit of a wall-mounted boiler, and more specifically, to a constant-temperature water circuit module. Background Art

[0002] The following problems are likely to occur during the use of the existing water circuit module of a wall-mounted boiler:

[0003] When the user switches from the heating function to domestic hot water after using the heating function, since the radiator is still at a relatively high temperature, the domestic hot water will be scalding hot in the first few seconds. This is a pain point of the radiator heating of the wall-mounted boiler. Generally, the human body needs domestic hot water below 50 degrees, and the radiator needs to be above 65 degrees. When there is radiator heating, because it is high-temperature water, it will cause the heat exchanger to get hot. At this time, suddenly using domestic hot water will cause the domestic hot water to be scalding hot in the first few seconds, resulting in high local water temperature, which not only affects the user experience but also has a risk of scalding. Therefore, it is urgent to improve this situation. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the above-mentioned deficiencies of the existing technology, and provide a constant-temperature water circuit module. A third connection port is provided at the shell, and normal-temperature tap water can enter the shell from the third connection port. Through the driver, the normal-temperature tap water can be mixed with the domestic hot water flowing out of the domestic heat exchanger outlet, so as to solve the problem of high local water temperature.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The utility model discloses a constant-temperature water circuit module, which includes a water outlet valve. The water outlet valve includes a shell and a driver. The shell includes a domestic heat exchanger outlet, a domestic hot water outlet and a third connection port. A first cavity and a second cavity are provided inside the shell. The domestic heat exchanger outlet, the first cavity and the domestic hot water outlet are connected to form a first water circuit. The third connection port is connected to the second cavity to form a second water circuit. The first water circuit and the second water circuit are connected or blocked through the driver.

[0007] Further, the driver includes a valve core. The valve core is inserted into the first cavity, and the valve core can move to connect or block the first cavity and the second cavity.

[0008] Further, the valve core can move downward so that the valve core abuts against the opening of the second cavity facing the first cavity to block the first cavity and the second cavity.

[0009] Further, a third cavity and a water passing channel are provided inside the shell. The third cavity is connected to the domestic heat exchanger outlet, and the third cavity is connected to the first cavity through the water passing channel.

[0010] Further, a first connection port and a second connection port are provided on the side of the housing. The first connection port and the second connection port are connected by a first connecting pipe. The first connection port communicates with the first cavity, and the second connection port communicates with the bathroom hot water outlet.

[0011] Further, the water outlet valve includes a second temperature sensor. The second temperature sensor is connected to the first connecting pipe, and the sensing head of the second temperature sensor is inserted into the first connecting pipe.

[0012] Further, the water outlet valve further includes a first temperature sensor, and the sensing head of the first temperature sensor is located inside the bathroom plate heat exchanger outlet.

[0013] Further, a water inlet valve is further included. The water inlet valve includes a domestic water inlet and a fourth connection port. The domestic water inlet communicates with the fourth connection port, and the fourth connection port communicates with the third connection port.

[0014] Further, the third connection port and the fourth connection port are connected by a second connecting pipe. A third temperature sensor is provided on the side of the second connecting pipe, and the sensing head of the third temperature sensor is inserted into the second connecting pipe.

[0015] Further, the water outlet valve includes a three-way servo. The three-way servo is connected to the housing. The housing includes a heating hot water inlet, a heating hot water outlet, and a bathroom plate heat exchanger outlet. The water inlet valve includes a bathroom plate heat exchanger inlet, a heating plate heat exchanger outlet, and a water pump interface. The heating hot water inlet and the heating hot water outlet are communicated or blocked by the three-way servo. The heating hot water inlet and the heating plate heat exchanger inlet are communicated or blocked by the three-way servo. The heating plate heat exchanger inlet and the heating plate heat exchanger outlet are communicated. The water pump interface is communicated with the heating plate heat exchanger outlet. The bathroom plate heat exchanger inlet and the bathroom plate heat exchanger outlet are communicated. The driver is a mixing servo valve.

[0016] The beneficial effects of the present utility model are as follows:

[0017] 1. When the user closes the shower for a period of time, the tap water in the plate heat exchanger in the first waterway does not flow. The hot water in the plate heat exchanger and the tap water will continuously exchange heat, and the water temperature of the tap water in the plate heat exchanger and near the plate heat exchanger will rise, resulting in a section of high-temperature tap water in the first waterway. When the user opens the shower again, this part of the high-temperature tap water flows. At this time, the driver connects the first waterway and the second waterway. When the high-temperature tap water in the first waterway flows into the first cavity, since the first cavity and the second cavity are communicated, the normal-temperature tap water in the second cavity can also flow into the first cavity and neutralize with the high-temperature tap water in the first cavity, reducing the water temperature of this part of the high-temperature tap water, thereby solving the problem of excessive local water temperature when the water comes out again after the water supply is cut off;

[0018] 2. Integrating the driver into the water outlet valve not only greatly reduces the overall structural size of the product, makes the structure more compact, occupies less space, and is beneficial to the design of small wall-mounted boilers, but also can effectively reduce pipeline connections and lower the risk of water leakage.

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0028] As Figures 1 to 7As shown in the figure, a constant temperature water circuit module includes a water inlet valve 6 and a water outlet valve 1.

[0029] The water inlet valve 6 includes a domestic water inlet 61, a sanitary heat exchanger inlet 62, a heating heat exchanger outlet 63, a water pump interface 64, a fourth connection port 65, a first installation port 66 and a second installation port 67. The domestic water inlet 61, the sanitary heat exchanger inlet 62 and the fourth connection port 65 are interconnected. The sanitary heat exchanger inlet 62 and the heating heat exchanger outlet 63 are respectively connected to a heat exchanger (not shown in the figure). The heating heat exchanger outlet 63 is communicated with the water pump interface 64. The water pump interface 64 can be connected to a water pump (not shown in the figure). A safety valve (not shown in the figure) can be installed at the first installation port 66, and a pressure gauge (not shown in the figure) can be installed at the second installation port 67. During use, normal temperature tap water enters the water inlet valve 6 from the domestic water inlet 61. A part flows out from the sanitary heat exchanger inlet 62 into the heat exchanger, and another part flows out from the fourth connection port 65 into the water outlet valve 1.

[0030] The water outlet valve 1 includes a housing 2, a three-way servo 3 and a driver 4. The housing 2 includes a heating hot water inlet 201, a heating hot water outlet 202, a sanitary heat exchanger outlet 203, a heating heat exchanger inlet 204 and a sanitary hot water outlet 207.

[0031] The three-way servo 3 is connected to the housing 2. The heating hot water inlet 201 and the heating hot water outlet 202 are communicated or blocked through the three-way servo 3. The heating hot water inlet 201 and the heating heat exchanger inlet 204 are communicated or blocked through the three-way servo 3. When the heating hot water inlet 201 and the heating hot water outlet 202 are communicated, it can supply heat for a floor heating system (not shown in the figure). When the heating hot water inlet 201 and the heating heat exchanger inlet 204 are communicated, hot water can enter the heat exchanger to exchange heat with the normal temperature tap water that enters the heat exchanger from the water inlet valve 6.

[0032] The connection structure between the three-way servo 3 and the housing 2, and the way the three-way servo 3 switches the heating hot water inlet 201, the heating hot water outlet 202 and the heating heat exchanger inlet 204 are all prior arts, so their specific structures and working principles are not described in detail in this specification.

[0033] Inside the housing 2, there are a first cavity 209 and a second cavity 210. The sanitary heat exchanger outlet 203, the first cavity 209 and the sanitary hot water outlet 207 are connected to form a first water path. Specifically, the heating heat exchanger inlet 204 and the heating heat exchanger outlet 63 are connected through a heat exchanger. The sanitary heat exchanger inlet 62 and the sanitary heat exchanger outlet 203 are connected through a heat exchanger. Inside the housing 2, there are a third cavity 211 and a water passage 212. The third cavity 211 is connected to the sanitary heat exchanger outlet 203. The third cavity 211 is connected to the first cavity 209 through the water passage 212. On the side of the housing 2, there are a first connection port 205 and a second connection port 206. The first connection port 205 and the second connection port 206 are connected through a first connecting pipe 5. The first connection port 205 is connected to the first cavity 209. The second connection port 206 is connected to the sanitary hot water outlet 207.

[0034] The first water path is the normal water outlet path. When discharging water normally, the normal temperature tap water enters the inlet valve 6 from the domestic water inlet 61, and successively passes through the sanitary heat exchanger inlet 62 and the heat exchanger. After the normal temperature tap water is heated by the heat exchanger, it flows out from the sanitary heat exchanger outlet 203, and successively passes through the third cavity 211, the water passage 212, the first cavity 209, the first connection port 205, the first connecting pipe 5, and the second connection port 206, and finally flows out from the sanitary hot water outlet 207. The water flowing out from the sanitary hot water outlet 207 is warm water.

[0035] The third connection port 208 is connected to the second cavity 210 to form a second water path. Specifically, on the side of the housing 2, there is a third connection port 208. The third connection port 208 and the fourth connection port 65 are connected through a second connecting pipe 7. A part of the normal temperature tap water entering the inlet valve 6 flows into the second cavity 210 through the fourth connection port 65, the second connecting pipe 7 and the third connection port 208.

[0036] The second water path is the normal temperature tap water path, which is used to reduce the water temperature of the warm water flowing out from the sanitary hot water outlet 207 and solve the problem of local high water temperature during water discharge. The first water path and the second water path are connected or blocked by the driver 4. When the user closes the shower head for a period of time, the tap water in the heat exchanger in the first water path does not flow. The hot water in the heat exchanger and the tap water will continuously exchange heat, and the water temperature of the tap water in the heat exchanger and near the heat exchanger will rise, resulting in a section of high temperature tap water in the first water path. When the user opens the shower head again, this part of the high temperature tap water flows. At this time, the driver 4 connects the first water path and the second water path. When the high temperature tap water in the first water path flows into the first cavity 209, since the first cavity 209 and the second cavity 210 are connected, the normal temperature tap water in the second cavity 210 can also flow into the first cavity 209 and neutralize with the high temperature tap water in the first cavity 209, reducing the water temperature of this part of the high temperature tap water, thereby solving the problem of too high local water temperature when discharging water again after the water supply is cut off.

[0037] When the user switches to domestic hot water after using the heating function, since the radiator is still at a relatively high temperature, the domestic hot water will be scalding hot in the first few seconds. Specifically, when heating, the water temperature in the plate heat exchanger is too high. At this time, when suddenly using domestic hot water, the normal temperature water flows through the high-temperature plate heat exchanger and the temperature rises significantly, resulting in the warm water flowing out of the bathroom hot water outlet 207 being scalding hot in the first few seconds, and it will also cause the problem of too high local water outlet temperature. By designing the second water path, the problem of high local water outlet temperature when switching from heating to domestic hot water can also be solved.

[0038] As Figure 4 and Figure 5 shown, the driver 4 is a mixing servo valve. The driver 4 includes a valve core 41. The valve core 41 is inserted into the first cavity 209. The valve core 41 can move to connect or block the first cavity 209 and the second cavity 210. Specifically, the valve core 41 can move downward so that the valve core 41 abuts against the opening of the second cavity 210 facing the first cavity 209 to block the first cavity 209 and the second cavity 210. The driver 4 is a prior art, and its specific structure is not described in detail in this specification. In this embodiment, integrating the driver 4 into the water outlet valve 1 not only greatly reduces the overall structural size of the product, makes the structure more compact, occupies less space, and is beneficial to the design of small wall-mounted boilers, but also can effectively reduce pipeline connections and reduce the risk of water leakage.

[0039] As Figures 4 - 6 shown, a guide member 213 is provided in the second cavity 210. The guide member 213 is connected to the side wall of the second cavity 210 through a connecting rib. A guide hole 214 is provided in the middle of the guide member 213. A guide rod 42 is provided at the lower part of the valve core 41. The guide rod 42 is inserted into the guide hole 214. The guide rod 42 can move up and down along the guide hole 214. Through the cooperation of the guide rod 42 and the guide hole 214, the accuracy of the up and down movement of the valve core 41 can be improved, thereby improving the sealing effect at the upper end opening of the second cavity 210.

[0040] The water outlet valve 1 further includes a first temperature sensor 11 and a second temperature sensor 12. The sensing head of the first temperature sensor 11 is located in the bathroom plate heat exchanger outlet 203. The first temperature sensor 11 is used to detect the water temperature flowing out from the bathroom plate heat exchanger outlet 203. The second temperature sensor 12 is connected to the first connecting pipe 5. The sensing head of the second temperature sensor 12 is inserted into the first connecting pipe 5. The second temperature sensor 12 is used to detect the water temperature in the first connecting pipe 5. A third temperature sensor 8 is provided on the side of the second connecting pipe 7. The sensing head of the third temperature sensor 8 is inserted into the second connecting pipe 7. The third temperature sensor 8 is used to detect the water temperature in the second connecting pipe 7.

[0041] The above are only the preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements should also be regarded as the protection scope of the present utility model.
