The water heater is a device for heating water conveyed by a municipal pipe network through a heating mechanism to form hot water so as to output the hot water to a user. The electric water heater and the gas water heater are classified according to different heating modes of the heating mechanism.
The electric water heater adopts electric energy as a main energy material, the heating mechanism is an electric heating component, and the high-temperature heat generated after the electric heating component is electrified directly heats water of the electric water heater so as to achieve the purpose of outputting hot water. Wherein, the electric heating part in the instant heating type electric water heater is provided with a cold water inlet and a hot water outlet so as to realize instant heating type heating water.
The gas water heater adopts gas as main energy material, the heating mechanism is a heat exchanger, and the high-temperature heat generated by combustion of the gas is transferred into cold water flowing through the heat exchanger to achieve the purpose of preparing hot water. The gas water heater is also a water heater for heating water instantly.
In order to reduce temperature fluctuation of water temperature output by the water heater, especially in the water switching process, the mixing proportion of cold water and hot water is effectively adjusted to reduce fluctuation of water outlet temperature, and therefore, the mixing adjusting valve is adopted for adjusting the cold water and hot water proportion in an embodiment of the application.
In a first embodiment, as shown in fig. 1 to 8, the mixing control valve of the present embodiment includes:
the water outlet valve comprises a valve shell 1, wherein a water inlet pipe 11, a first water outlet pipe 12 and a second water outlet pipe 13 are arranged on the valve shell 1, a first water outlet 121 for water outlet is arranged in the first water outlet pipe 12, a partition plate 15 is arranged in the second water outlet pipe 13, and a second water outlet 131 for water outlet is arranged on the partition plate 15; wherein the water inlet pipe 11 and the second book outlet pipe are arranged on the side wall of the valve housing 1, and the first water outlet pipe 12 is arranged at one end part of the valve housing 1
The flow restricting assembly 2, the flow restricting assembly 2 includes a driving part (not shown), a first moving part 21 and a second moving part 22, the first moving part 21 and the second moving part 22 being slidably disposed in the valve housing 1, the driving part being configured to drive the first moving part 21 and the second moving part 22 to reciprocally slide in the valve housing 1, the first moving part 21 being configured to be close to or far from the first water outlet 121 to adjust the opening degree of the first water outlet 121, and the second moving part 22 being configured to be close to or far from the second water outlet 131 to adjust the opening degree of the second water outlet 131.
Specifically, the mixing control valve of the present embodiment is assembled by the valve housing 1 and the restrictor assembly 2, wherein the valve housing 1 is configured with the water inlet pipe 11, the first water outlet pipe 12 and the second water outlet pipe 13, the water inlet pipe 11 is used for introducing the water flow, and the water flow is output from the first water outlet pipe 12 and/or the second water outlet pipe 13 as required after entering the valve housing 1.
During assembly, the first and second moving parts 21 and 22 are provided in the valve housing 1 to satisfy the adjustment of the opening degrees of the first and second water outlets 121 and 131 formed in the valve housing 1. And the driving member is installed outside the valve housing 1 after the first and second moving members 21 and 22 are assembled into the valve housing 1.
In the practical application process, the mixing regulating valve is arranged on the water heater. For water heaters, they generally comprise a water heater body provided with a total water inlet port and a total water outlet port, the water heater body also being provided with a heating mechanism; the water inlet pipe 11 is connected with the total water inlet port, the first water outlet pipe 12 is connected with the inlet of the heating mechanism, and the second water outlet pipe 13 and the outlet of the heating mechanism are respectively connected with the total water outlet port.
The main water inlet port is connected with a water supply pipe (such as a tap water pipe) in the user's home, and the main water outlet port is connected with a water terminal (such as a shower or a tap water) through the water pipe in the user's home.
In the use process, in the normal heating process, the driving part drives the first moving part 21 to move away from the first water outlet 121 so as to adjust the first water outlet pipe 12 to be at the maximum opening degree and further obtain the maximum water flow; at the same time, the second moving part 22 moves synchronously in the same direction along with the first moving part 21 to close the second water outlet pipe 13, i.e. the bypass flow path is in a cut-off position.
In the normal water use process, the power of the heating mechanism is reduced due to the influence of external factors, and at this time, the flow of the first water outlet pipe 12 needs to be regulated. At this time, the driving part drives the first moving part 21 and the second moving part 22 to move towards the first water outlet 121, and the first moving part 21 correspondingly reduces the opening of the first water outlet 121 to reduce the water flow of the first water outlet pipe 12, so as to maintain the constant water temperature output by the water heater.
However, the second moving member 22 moves along with the first moving member 21, but the movement stroke is insufficient to expose the second water outlet 131, so that the second water outlet 131 is still in a closed state. In the process, according to the difference between the water outlet temperature and the set temperature of the water heater, the driving part drives the first moving part 21 to move in the forward and backward directions so as to dynamically adjust the water outlet temperature.
In the case where the water outlet temperature of the water heater is continuously high during the adjustment of the first moving member 21, it is necessary to further reduce the water flow into the heating mechanism and, at the same time, to open the bypass water flow. At this time, the driving part 21 drives the first moving part 21 and the second moving part 22 to move continuously towards the first water outlet 121, the first moving part 21 further reduces the opening degree of the first water outlet 121 to reduce the water flow rate of the first water outlet pipe 12, and correspondingly, the second moving part 22 exposes the second water outlet 131 to open the second water outlet pipe 13. The bypass duty ratio is dynamically adjusted by controlling the water flow ratio of the first water outlet pipe 12 and the second water outlet pipe 13 so as to maintain the constant water temperature output by the water heater.
In addition, when the user normally uses the water heater, the flow limiting assembly 2 will simultaneously adjust the opening of the first water outlet 121 and the second water outlet 131 when the user uses water twice in a short time, so as to reduce the flow of cold water flowing into the heating mechanism and increase the bypass cold water, so as to increase the lowest temperature of water flowing out of the water heater, reduce the highest temperature of water flowing out of the water heater, further meet the requirement of constant-temperature water outlet of the water heater, and further improve the shower experience of the user.
In an embodiment of the present application, the first moving part 21 includes a mounting sleeve 211, a rotating shaft 212 and a plug 213, the mounting sleeve 211 is disposed in the valve housing 1, a threaded hole (not labeled) is disposed in the mounting sleeve 211, the rotating shaft 212 penetrates through the mounting sleeve 211, one end portion of the rotating shaft 212 extends out of the valve housing 1 and is connected with the driving part, the other end portion of the rotating shaft 212 extends to the first water outlet 121 and is provided with the plug 213, a threaded portion 2121 is disposed on the rotating shaft 212, the threaded portion 2121 is in threaded connection with the threaded hole, and the plug 213 is disposed opposite to the first water outlet 121.
Specifically, for the first water outlet pipe 12, the first water outlet 121 is disposed at a position of one end of the valve housing 1, and in order to realize that the first moving component 21 adjusts the opening of the first water outlet 121, the rotating shaft 212 is matched with the mounting sleeve 211, so that the rotating shaft 212 can also reciprocate along the axis of the valve housing 1 in the rotating process, and further the plug 213 is driven to approach or separate from the first water outlet 121, so as to realize that the opening of the first water outlet 121 is adjusted.
In another embodiment, in order to facilitate the driving of the second moving part 22 by the driving part, the second moving part 22 is an annular enclosure, which is arranged on the shaft 212 and rests against the inner wall of the valve housing 1.
Specifically, the annular enclosure is arranged on the rotating shaft 212, and the annular enclosure can rotate and move along with the rotating shaft 212 in the rotating and moving process of the rotating shaft 212. The annular enclosure is integrally in a cylindrical structure, and can well cover the second water outlet 131 in the process of driving the rotary shaft 212 to rotate, so as to ensure that the second water outlet 131 is in a closed state.
In another embodiment, when the opening degrees of the first water outlet 121 and the second water outlet 131 are adjusted, the water inflow of the water inlet pipe 11 can be adjusted synchronously for better adjusting the total water flow. Specifically, a water inlet 111 for water inflow is arranged in the water inlet pipe 11; one end of the annular enclosure is provided with a notch 221, and the notch 221 is configured to adjust the opening of the water inlet 111 during rotation.
Specifically, during the process of adjusting the first water outlet 121 and the water outlet through the flow-limiting assembly 2, especially during the process of reducing the opening of the first water outlet 121, the inflow of the water inlet pipe 11 is correspondingly throttled. Therefore, the water inflow and the water outflow can be matched more, the water temperature control precision is improved more favorably, and the experience of a user in using the water heater is improved.

In addition, even if water flows in the valve housing 1, under the supporting action of the protrusions 223, the annular surrounding block cannot be askew and dead due to water flow impact, so that the use reliability is improved.
