Description

Technical Field

[0001] The utility model relates to the technical field of automatic temperature control systems for faucets, in particular to a shell of a water temperature controller for keeping water at a constant temperature, wherein the water temperature controller is particularly suitable for use in a shower system. Background Art

[0002] At present, the intelligent faucet has poor stability in terms of realizing intelligence, and has not well combined intelligent technology with functional experience, ignoring the convenience and stability of using intelligent faucets. At present, the intelligent valve control systems on the market are basically controlled by a flat-opening water mixing valve core. For example, a Chinese invention patent application with application number CN202210152317.1 (publication number CN114484009A) discloses "a control valve and its control method" and discloses such a flat-opening water mixing valve core that can realize intelligent control, including a valve body and a main control board, a valve core for controlling the water outlet temperature and the water outlet flow rate is arranged in the valve body, an execution unit 1 and an execution unit 2 are arranged on the valve body, a detection unit 1 for detecting the water flow temperature and a detection unit 2 for detecting the water flow pressure are arranged on the valve body, the main control board can receive the signal of the detection unit 1 and drive the valve core to control the water outlet flow through the execution unit 1, and the main control board can receive the signal of the detection unit 2 and drive the valve core to control the water outlet temperature through the execution unit 2.

[0003] The above solution has the following defects:

[0004] 1. Due to the large fluctuations in hot water pressure or hot water temperature in most users' usage scenarios, the valve core needs to rotate continuously to adjust the temperature. The valve core does not react quickly to water pressure fluctuations. Due to the water pressure difference, the fluctuation range of water output becomes larger, and the water temperature will fluctuate in a certain period of time, affecting the experience.

[0005] 2. This type of intelligent control box currently has only one water outlet, which is not convenient for use in a shower system. If it is to be used in a shower system, an additional water distribution faucet needs to be installed after the water outlet, resulting in a more dispersed control part.

[0006] 3. It has only one temperature sensor, and it is set at the end. It can only compare the outlet water temperature with the set temperature. It may also cause the outlet water temperature to be extremely unstable. The outlet water temperature will be too high or too low, and the user experience will be poor. Since the water inlet pressure and flow rate are unknown, multiple adjustments are required to reach the set temperature.

[0007] To this end, it is necessary to design a shell structure with multiple water outlet channels, which can be equipped with multiple valve cores, multiple sensors and other multiple functional valve cores. Because the internal channels of this shell structure are very complex, the structural rationality of the shell is very important. It must not only meet the design requirements of the complexity of the internal channels, but also must take into account the design requirements of convenient one-piece molding. Utility Model Content

[0008] The first technical problem to be solved by the utility model is to provide a shell of a water temperature controller with multiple internal channels and chambers, reasonable layout and convenient one-piece molding in view of the current status of the prior art.

[0009] The technical solution adopted by the utility model to solve the above-mentioned first technical problem is: a shell of a water temperature controller, including a valve seat, the valve seat has a cold water inlet channel, a hot water inlet channel, a first valve core installation cavity, a second valve core installation cavity, a cold water outflow channel, a hot water outflow channel, a mixing water cavity and a mixed water outflow channel, the cold water outflow channel and the hot water outflow channel are connected with the mixing water cavity, and the mixing water cavity is connected with the mixed water outflow channel; it is characterized in that: the cold water outflow channel and the hot water outflow channel are coaxially arranged laterally along a third axis, the cold water outflow channel transversely penetrates the side wall of the first valve core installation cavity, and a first plug is provided at the perforation position of the side wall of the first valve core installation cavity, the hot water outflow channel transversely penetrates the side wall of the second valve core installation cavity, and a second plug is provided at the perforation position of the side wall of the second valve core installation cavity.

[0010] To further facilitate the forming of each flow channel in the valve seat, the above-mentioned cold water outflow channel, hot water outflow channel, mixed water outflow channel and mixing water chamber are located between the first valve core installation chamber and the second valve core installation chamber, the first valve core installation chamber and the cold water inlet flow channel are coaxially vertically arranged and connected along the first axis, the second valve core installation chamber and the hot water inlet flow channel are coaxially vertically arranged and connected along the second axis, the axes of the cold water inlet flow channel and the hot water inlet flow channel are parallel and the mouth ends are facing downward, and the mouth ends of the first valve core installation chamber and the second valve core installation chamber are facing upward. The axes of the cold water inlet channel and the hot water inlet channel are parallel and their mouth ends are facing downward, which is conducive to the connection of the cold water inlet pipe, the hot water inlet pipe and the outlet pipe with the valve seat. The connection directions of each water pipe are connected from bottom to top, which makes the connection more convenient and reasonable. The mouth ends of the first valve core installation cavity and the second valve core installation cavity face upward, which is conducive to the installation of the valve core in the installation cavity. Because the water inlet channel and the corresponding valve core installation cavity are coaxially arranged and connected from top to bottom, it is conducive to the molding of the product and it is more convenient to pull the mold core during the manufacturing process.

[0011] As a further improvement, the valve seat also has a third valve core installation cavity located between the first valve core installation cavity and the second valve core installation cavity, and the mouth of the third valve core installation cavity faces downward. In addition, the third valve core installation cavity provides an installation position for the balance valve core, so that when the water temperature controller using the housing encounters water pressure fluctuations of hot and cold water, the flow of hot and cold water can be adjusted by moving the piston in the balance valve core to ensure that the two are mixed according to the preset ratio, effectively solving the problem that the fluctuation range of the water output becomes larger due to the water pressure difference, and the water temperature of the water output fluctuates between hot and cold in a certain period of time.

[0012] In order to facilitate the parting of the mold during molding, the third valve core installation cavity is arranged below the third axis, the water mixing cavity is arranged above the third axis, the third valve core installation cavity and the water mixing cavity are coaxially arranged vertically along the fourth axis and connected, the water end of the water mixing cavity is open and the mouth end faces upward, and the third valve core installation cavity is located below the water mixing cavity. The water mixing cavity and the third valve core installation cavity can be re-examined by simply pulling the core in the up and down directions, which is convenient for pulling the core during the molding process. The water mixing cavity and the third valve core installation cavity can be formed by pulling the core on both sides at the same time.

[0013] As a further improvement, there are multiple mixed water outflow channels, and the outlet end of each mixed water outflow channel passes through the front side wall and / or the rear side wall of the valve seat. The valve seat has a fourth valve core installation cavity located between the first valve core installation cavity and the second valve core installation cavity, and the mouth end of the fourth valve core installation cavity faces upward. In this way, a water diversion valve core can be installed in the fourth valve core installation cavity. After the cold and hot water are mixed in the mixing water cavity, they flow to the water diversion valve core, and the water is directed to one of the mixed water outflow channels through the water diversion valve core. The corresponding mixed water outflow channel is connected to the corresponding water outlet structure (shower, faucet, overhead spray) in the shower system, and there is no need to set an additional water diversion valve outside the module. Therefore, this module has a compact structure and good integrity, and is particularly suitable for shower systems.

[0014] The fourth valve core installation cavity is arranged above the third axis. The valve core can be installed from the top downward.

[0015] Preferably, the first plug and the second plug are both threadedly connected to the valve seat, and the threaded connection facilitates the installation of the first plug and the second plug on the valve seat.

[0016] As a further improvement, the side wall of the valve seat is provided with a first sensor mounting hole connected to the cold water outflow channel, a second sensor mounting hole connected to the hot water outflow channel, and a third sensor mounting hole connected to the mixing water chamber. The water temperature controller using this shell can automatically adjust the outlet water temperature quickly and accurately. The flow rate and water temperature of cold water and hot water are detected by the temperature sensor, and the detected flow rate and water temperature data are sent to the information control module. The information control module will adjust the outlet water temperature quickly and accurately according to the model (the model knows how much flow rate of hot water and how much flow rate of cold water are mixed to obtain mixed water with the corresponding flow rate and temperature), that is, it roughly knows how much angle range the movable valve plates of the two flow regulating valve cores need to rotate respectively so that the mixed water can reach the set temperature and flow rate. At this time, the movable valve plate of the flow regulating valve core will rotate to an angle in advance (this angle is close to the angle that needs to be rotated to in the end), and finally compare it with the water temperature signal of the mixed water measured by the sensor. The information control module sends a final signal to the two motor control modules, and the movable valve plate of the flow regulating valve core can quickly rotate to the correct angle. Because its response speed is very fast, the problem of the mixed water outlet being hot and cold will be significantly improved.

[0017] As an improvement, the first plug is provided with a fourth sensor installation hole connected to the cold water outflow channel. The first plug provides a suitable installation position for the sensor.

[0018] As an improvement, a fifth valve core installation cavity is further provided in the valve seat, and the fifth valve core installation cavity is located between the third valve core installation cavity and the water mixing cavity, and the three are connected. The fifth valve core installation cavity can be installed with a manual switch valve core for manually controlling the water outlet of the water mixing cavity, so that when the motor is damaged, the total water outlet can be manually closed, which is more user-friendly.

[0019] In order to allow the manual switch valve core to be installed laterally into the valve seat, the side wall of the fifth valve core installation cavity is provided with an opening.

[0020] Compared with the prior art, the technical solution of the utility model has the following advantages: the valve housing is provided with a plurality of flow channels and valve core installation cavities, and a plurality of valve cores can be installed, which provides convenience for realizing automatic control of water temperature; the cold water outflow channel, the hot water outflow channel, the mixed water outflow channel and the mixed water chamber are located between the first valve core installation chamber and the second valve core installation chamber, and the cold water and hot water on both sides flow toward the middle position, which can make the water flow quickly mixed, and the layout of each flow channel is reasonable; furthermore, the cold water outflow channel and the hot water outflow channel correspond to pass through the first valve core installation chamber and the second valve core installation chamber and are located on the same axis (the third axis) and are arranged horizontally, so that the cold water outflow channel and the hot water outflow channel can be formed by lateral core pulling.
