Description

Technical Field

[0001] This utility model relates to the field of bathroom equipment technology, and in particular to a hot water and cold water mixing device and a bathroom water temperature control system having the same. Background Technology

[0002] Valves are control components in pipeline fluid transport systems, used to change the cross-sectional area of ​​the passage and the direction of medium flow. They have functions such as guiding, stopping, throttling, checking back, diverting or overflowing and relieving pressure. Hot and cold water mixing devices are devices in bathroom facilities used to control the direction, flow rate, and pressure of water flow. Temperature regulating valves can regulate the temperature of hot water and are usually installed in water heaters to regulate the temperature of hot water.

[0003] In existing technologies, hot and cold water mixing devices are typically installed on the water supply pipe of the water heater. Users need to adjust the valves before showering to mix the hot and cold water to a suitable temperature. However, in current bathroom water temperature control systems, the hot and cold water valves are separate components connected to the mixing chamber via connecting pipes. This separate design results in a fragmented structure, larger size, and greater space requirements. Furthermore, because some hot or cold water remains in the long connecting pipe, when a user wants to lower the temperature, the hot and cold water valves control the flow of less hot water and more cold water into the mixing chamber to reduce the temperature. However, the remaining hot water in the connecting pipe leads to a prolonged period of high water temperature in the mixing chamber, requiring the user to wait for a while before reaching the desired temperature. This lag in temperature control prevents timely adjustment to the desired shower temperature, resulting in a poor user experience and failing to meet user needs. Utility Model Content

[0048] Please refer to the following: Figures 1 to 10 This embodiment provides a bathroom water temperature control system, including an electronic temperature control component 200 and a hot water and cold water mixing device 100. The hot water and cold water mixing device 100 is electrically connected to the electronic temperature control component 200. A mounting hole 212b is provided on the side wall of the mixing outlet pipe 124. A temperature sensor 300 for detecting the temperature of the mixed water in the mixing outlet pipe 124 is installed in the mounting hole 212b. The temperature sensor 300 is electrically connected to the electronic temperature control component 200 so that the electronic temperature control component 200 controls the water flow diameter of the hot water outlet 111 and the cold water outlet 112 of the hot water mixer 110 according to the water temperature detected by the temperature sensor 300.

[0049] The hot and cold water mixing device 100 includes a hot and cold water mixer 110 and a housing 120. The hot and cold water mixer 110 has a mixing chamber inside. One end of the hot and cold water mixer 110 has a hot water inlet 111, a cold water inlet 112, and a water outlet 113. The hot and cold water mixer 110 can adjust the water flow diameter of the hot water inlet 111 and the cold water inlet 112. The housing 120 includes a housing body 121, a hot water pipe 122, a cold water pipe 123, and a mixed water outlet pipe 124. One end of the housing body 121 is provided with an opening 121a so that the housing body 121 can be fitted onto one end of the hot and cold water mixer 110 through the opening 121a. The hot water pipe 122 is connected to the hot water inlet 111, the cold water pipe 123 is connected to the cold water inlet 112, and the mixed water outlet pipe 124 is connected to the water outlet 113. The hot water pipe 122 and the cold water pipe 123 are respectively provided on both sides of the other end of the housing body 121.

[0050] With this configuration, this embodiment provides a mixing chamber inside the hot and cold water mixer 110, and provides a hot water outlet 111 and a cold water outlet 112 at one end of the hot and cold water mixer 110, so that hot and cold water can mix in the mixing chamber when the hot water outlet 111 and the cold water outlet 112 are opened. A water outlet 113 is also provided at one end of the hot and cold water mixer 110 to discharge the mixed water. By providing an outer casing 120, in which the hot water pipe 122 is connected to the hot water outlet 111, the cold water pipe 123 is connected to the cold water outlet 112, and the mixed water outlet pipe 124 is connected to the water outlet 113, and the hot water pipe 122 and the cold water pipe 123 are respectively provided on both sides of the other end of the outer casing 121, and the water outlet 113 is also provided at the other end of the outer casing 121, the hot and cold water mixing device 100 with this configuration has a compact structure, which can effectively reduce the volume of the hot and cold water mixing device 100 and enhance the versatility of the hot and cold water mixing device 100.

[0051] As can be seen, the hot and cold water mixing device 100 and the bathroom water temperature control system provided in this embodiment allow the user to specify the output water temperature. By inputting the specified temperature into the electronic temperature control component 200, the electronic temperature control component 200 can drive the hot and cold water mixing device 100 to work and output the specified temperature. A mounting hole 212b is provided on the side wall of the mixing outlet pipe 124. A temperature sensor 300 for detecting the mixed water temperature in the mixing outlet pipe 124 is installed in the mounting hole 212b. The temperature sensor 300 and... The electronic temperature control component 200 is electrically connected so that it can control the water flow diameter of the hot water inlet 111 and cold water inlet 112 of the hot and cold water mixer 110 according to the water temperature detected by the temperature sensor 300. This further improves the accuracy of the output water temperature. In this way, the compact structure can also reduce water stagnation inside, thereby reducing the impact of stagnant water on the output water flow. This allows users to quickly and in real time adjust the water temperature, enabling users to obtain the desired water temperature more quickly and improving the user experience.

[0052] The internal structure and principle of the hot and cold water mixer 110 and the control program of the electronic temperature control component 200 in this embodiment are all existing technologies. Existing mature components can be purchased for the hot and cold water mixer 110, and its specific structure will not be described in detail here.

[0053] In this embodiment, the other end face of the outer shell body 121 is provided with a hot water connection port 121b, a cold water connection port 121c, and a mixing connection port 121d. The hot water connection port 121b is correspondingly fitted to the hot water outlet 111 and is connected to the hot water pipe 122. The cold water connection port 121c is correspondingly fitted to the cold water outlet 112 and is connected to the cold water pipe 123. The mixing connection port 121d is correspondingly fitted to the water outlet 113 and is connected to the mixing water outlet pipe 124.

[0054] The structure is compact by providing a hot water connection port 121b, a cold water connection port 121c, and a mixing connection port 121d on the end face of the other end of the outer shell 121. Rubber sealing rings are also provided between the hot water connection port 121b and the hot water outlet 111, between the cold water connection port 121c and the cold water outlet 112, and between the mixing connection port 121d and the outlet 113 to improve the sealing between the outer shell 121 and the hot and cold water mixing device 100 and prevent leakage. The compact structure makes the space layout more reasonable and reduces the volume. On the other hand, it can reduce the water flow stagnation inside, allowing users to quickly and in real time adjust the water temperature.

[0055] Furthermore, the hot water pipe 122 and / or the cold water pipe 123 are provided with a connecting port 125 so that water pipes can be installed on the hot water pipe 122 and / or the cold water pipe 123 through the connecting port 125; and / or, the hot water pipe 122, the cold water pipe 123, the mixed water outlet pipe 124 and the outer shell body 121 are integrally formed structures.

[0056] In this embodiment, the connecting pipe 125 has an internal thread structure. By setting a connector with an external thread structure at one end of the water pipe, the water pipe can be threaded to the hot water pipe 122 and / or the cold water pipe 123. This setting makes the connection of the water pipe simple and facilitates the installation of the hot water and cold water mixing device 100 by workers. The one-piece molding structure design can make the outer shell 120 structurally stronger and improve production efficiency.

[0057] Furthermore, the central axis of the hot water pipe 122 is perpendicular to the central axis of the hot and cold water mixer 110, the central axis of the cold water pipe 123 is perpendicular to the central axis of the hot and cold water mixer 110; and / or, the central axis of the mixed water outlet pipe 124 is parallel to the central axis of the hot and cold water mixer 110.

[0058] The central axis of the mixing outlet pipe 124 is set parallel to the central axis of the hot and cold water mixer 110, which is conducive to the smooth flow of water from the outlet 113 of the hot and cold water mixing device 100, reduces the turning and resistance of the water flow after flowing out of the hot and cold water mixing device 100, and ensures the smoothness of the water flow. This arrangement can also further increase the compactness of the system structure.

[0059] Furthermore, the outer peripheral surface of the hot and cold water mixer 110 is provided with an external thread 114, and the inner peripheral surface of the opening 121a of the outer casing 121 is provided with an internal thread 121e. The outer casing 121 and the hot and cold water mixer 110 are connected by threads. The threaded connection makes the installation process of the outer casing 121 and the hot and cold water mixer 110 simple and convenient. During assembly, simply align the internal thread 121e of the outer casing 121 with the external thread 114 of the hot and cold water mixer 110 and rotate it to fit the outer casing 121 onto the hot and cold water mixer 110. No complicated tools or special installation techniques are required. Similarly, when it is necessary to disassemble the outer casing 121 for maintenance, inspection or replacement of internal parts, the outer casing 121 can be easily removed from the hot and cold water mixer 110.

[0060] In this embodiment, a multi-way switching valve 400 is also included. The multi-way switching valve 400 includes a valve body 410 and a switching component 420. The valve body 410 has an inlet 411 and a plurality of branch outlets 412. The inlet 411 is connected to the mixed water outlet pipe 124. The plurality of branch outlets 412 are arranged at intervals along the circumference of the valve body 410. The switching component 420 is used to switch the plurality of branch outlets 412 to be connected to the inlet 411 respectively.

[0061] The switching component 420 includes a switching element and a driving element. The switching element is driven to connect with the driving element so that when the driving element is activated, the switching element can switch multiple branch ports 412 to connect with the inlet port 411. Different branch ports 412 are connected to different shower devices, including shower heads, faucets, and overhead shower heads. The driving element is electrically connected to the electronic temperature control component 200, and the user can set different shower devices to work on the electronic temperature control component 200.

[0062] Furthermore, the switching assembly 420 includes a limiting ring 421. The outer circumferential surface of the limiting ring 421 is provided with multiple limiting grooves 421a. The limiting ring 421 can rotate within the valve body 410 to multiple switching positions, allowing the inlet 411 within the valve body 410 to connect with multiple branch ports 412 respectively. A limit switch 430 is provided within the valve body 410, and the limit switch 430 is provided with an elastic protrusion 431. When the limiting ring 421 rotates to the corresponding switching position, the elastic protrusion 431 will engage with the corresponding... The limiting groove 421a is used to achieve circumferential positioning of the rotation of the limiting ring plate 421. The limiting switch 430 is electrically connected to the electronic temperature control component 200 so that the electronic temperature control component 200 automatically controls the limiting ring plate 421 to rotate to the corresponding switching position and then stops according to the signal of the limiting switch 430. By setting the limiting switch 430 as the switching position of the switching component 420, the positioning effect is achieved, so that when the switching component 420 switches to the corresponding switching position, only the corresponding diversion port 412 will output water, thus improving the accuracy of the system.

[0063] In this embodiment, the electronic temperature control component 200 includes a control panel and a circuit board 220. The control panel includes an upper cover 211 and a lower cover 212 that fit together. An installation space is formed between the upper cover 211 and the lower cover 212. At least one wire hole 212a is provided on the lower cover 212. The hot water and cold water mixing device 100 is installed on the lower cover 212. The circuit board 220 is disposed in the installation space, and the wires pass through the wire hole 212a to electrically connect the circuit board 220 to the hot water and cold water mixing device 100.

[0064] The control panel provides an installation space for the circuit board 220. By installing the circuit board 220 into the installation space, moisture, dust and other impurities will not come into contact with the circuit board 220, thereby preventing damage to the electronic temperature control component 200. The circuit board 220 controls the drive motor to work, thereby achieving the effect of regulating the water temperature.

[0065] Furthermore, the upper cover 211 has a threaded post 211a on the side facing the lower cover 212, and the lower cover 212 has a corresponding mounting hole 212b, so that the upper cover 211 and the lower cover 212 can be assembled by passing a screw through the mounting hole 212b and screwing it into the threaded post 211a. The upper cover 211 has a display window 211b, and a display screen 221 is provided on the circuit board 220. The display screen 221 is located in the display window 211b. The upper cover 211 has a touch screen 211c on the side facing away from the lower cover 212, so that the circuit board 220 can be operated by touching the touch screen 211c to control the operation of the hot water and cold water mixing device 100.

[0066] The assembly process between the upper cover 211 and the lower cover 212 is simplified by setting threaded post 211a and mounting hole 212b. The display screen 221 is used to display key information such as water temperature. The circuit board 220 can be operated by pressing the touch screen 211c so that the circuit board 220 controls the hot water and cold water mixing device 100 to work.

[0067] As can be seen from the above description, the above embodiments of this utility model achieve the following technical effects: By setting a mixing chamber inside the hot and cold water mixer 110, and opening a hot water outlet 111 and a cold water outlet 112 at one end of the hot and cold water mixer 110, hot water and cold water can be mixed in the mixing chamber when the hot water outlet 111 and the cold water outlet 112 are opened. An outlet 113 is also provided at one end of the hot and cold water mixer 110 to discharge the mixed water. An outer casing 120 is provided, wherein a hot water pipe 122 is connected to the hot water outlet 111, a cold water pipe 123 is connected to the cold water outlet 112, and a mixed water outlet pipe 124 is connected to the outlet. The outlet 113 is connected, and the hot water pipe 122 and the cold water pipe 123 are respectively located on both sides of the other end of the outer casing 121. The outlet 113 is also located at the other end of the outer casing 121. The hot water and cold water mixing device 100 with such a configuration has a compact structure, which can effectively reduce the volume of the hot water and cold water mixing device 100 and enhance the versatility of the hot water and cold water mixing device 100. Moreover, due to its compact structure, it can reduce the water flow stagnation inside, thereby reducing the impact of stagnant water flow on the output water temperature. This allows users to quickly and in real time adjust the water temperature, enabling users to obtain the desired water temperature more quickly and improving the user experience.
