Technical Field

[0001] This utility model relates to the field of valve body technology, and in particular to a novel water inlet valve and water heater. Background Technology

[0002] Existing three-way inlet valves typically include an inlet channel and two outlet channels connected to it. The inlet channel contains a temperature sensor to detect the water temperature, and each outlet channel has a solenoid valve to open or close it. Thus, the temperature sensor controls the corresponding solenoid valve to open or close based on the detected inlet water temperature, determining which outlet channel the water flows from.

[0003] However, because it requires two solenoid valves to control the two water outlet channels separately, it is not only costly but also structurally complex. Utility Model Content

[0041] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0042] See Figures 1 to 7 This application first discloses a novel water inlet valve, including a valve body 1 and a valve core 2. The valve body 1 has an inlet channel, a first outlet channel, and a second outlet channel inside, and both the first outlet channel and the second outlet channel are connected to the inlet channel. The valve core 2 is rotatably disposed in the inlet channel and has a through hole connected to the inlet channel. When the valve core 2 is rotated until its through hole is connected to the first outlet channel, the inlet channel is connected to the first outlet channel. When the valve core 2 is rotated until its through hole is connected to the second outlet channel, the inlet channel is connected to the second outlet channel.

[0043] Additionally, it includes a temperature sensor 3 and a drive assembly. The temperature sensor 3's sensing head 31 is located inside the water inlet channel and is used to detect the temperature of the water flowing through the water inlet channel. The drive assembly includes a drive device 5 and a control board. The output end of the drive device 5 is connected to the valve core 2. The control board is electrically connected to both the drive device 5 and the temperature sensor 3. Preferably, the drive device 5 is a drive motor.

[0044] Therefore, the temperature sensor 3 detects the temperature of the water flowing into the inlet channel and sends the signal to the control board for comparison with a preset temperature value. When the water temperature is lower than the preset temperature, the control board controls the drive device 5 to rotate the valve core 2 and connect the through hole on the valve core 2 with the first outlet channel. At this time, the inlet channel and the first outlet channel are connected, and the water flowing into the inlet channel can flow out through the first outlet channel. When the water temperature is higher than the preset temperature, the control board controls the drive device 5 to rotate the valve core 2 and connect the through hole on the valve core 2 with the second outlet channel. At this time, the inlet channel and the second outlet channel are connected, and the water flowing into the inlet channel can flow out through the second outlet channel.

[0045] Therefore, by setting a rotatable valve core 2 in the water inlet channel, and by using the connection between the through hole on the valve core 2 and the first or second water outlet channel to control the opening or closing of the first or second water outlet channel, compared with the traditional control using two solenoid valves, the structure is not only simple but also the cost is lower.

[0046] For details, please refer to Figure 2-3The valve body 1 includes a cylindrical main body 11, and a first groove 111 that runs vertically through the main body 11 to form a water inlet channel. A first water outlet 12 and a second water outlet 13 are arranged circumferentially on the outer side of the valve body 1. The first water outlet 12 has a second groove 121 that connects to the first groove 111 to form a first water outlet channel. The second water outlet 13 has a third groove 131 that connects to the first groove 121 to form a second water outlet channel.

[0047] See Figure 4 as well as Figure 7 The valve core 2 is rotatably disposed within the first groove 111. The bottom of the valve core 2 has a fourth groove 21 communicating with the first groove 111, and the side of the valve core 2 has a through hole communicating with the fourth groove 21. This through hole includes a first through hole 22 and a second through hole 23 arranged circumferentially. When the valve core 2 is rotated until the first through hole 22 communicates with the second groove 121, the first water outlet channel is connected to the water inlet channel, and the second through hole 23 is not connected to the third groove 131. When the valve core 2 is rotated until the second through hole 23 communicates with the third groove 131, the second water outlet channel is connected to the water inlet channel, and the first through hole 22 is not connected to the second groove 121.

[0048] See Figure 1 and Figure 7 The valve core 2 is also fitted with a bearing 7 on its top, and the valve core 2 is rotatably mounted in the first groove 111 via the bearing 7. In addition, it also includes a sealing ring 8 fitted around the outer periphery of the valve core 2. There are two sealing rings 8, and both sealing rings 8 are fitted around the outer periphery of the valve core 2 and are arranged vertically at intervals. The outer walls of the two sealing rings 8 abut against the inner sidewall of the first groove 111 to achieve a waterproof seal.

[0049] In this embodiment, the valve core 2 has two annular grooves 24 arranged at intervals on its outer periphery, and two sealing rings 8 are respectively fitted onto the two annular grooves 24.

[0050] Additionally, a pressure plate 6 is included, with the valve body 1 mounted on the bottom of the pressure plate 6 by screws, and the drive motor mounted on the top of the pressure plate 6 by screws. The valve core 2 is also provided with a connector 25 on its top, which passes through the pressure plate 6 and connects to the output head of the drive motor to achieve a transmission connection.

[0051] In addition, the valve body 1 is provided with a mounting nozzle 14 on its side. The mounting nozzle 14 has a mounting groove 141 that connects to the first groove 111. The temperature sensor 3 passes through the mounting groove 141. The temperature sensor 3 also includes a sealing sleeve 32 fitted onto the temperature sensing head 31. The temperature sensing head 32 passes through the mounting groove 141 and extends into the water inlet channel. The sealing sleeve 32 abuts against the connection between the mounting groove 141 and the water inlet channel to achieve a waterproof seal.

[0052] In addition, it also includes a locking bolt 4. The mounting groove 141 has an internal thread that mates with the locking bolt. The locking bolt 4 is threaded into the mounting groove 141 and presses and fixes the sealing sleeve 32 at the connection between the mounting groove 141 and the water inlet channel.

[0053] In this embodiment, the temperature sensor 3 is an NTC temperature sensor.

[0054] In addition, this utility model also provides a water heater, including the above-mentioned novel inlet valve.

[0055] In summary, this utility model has the following technical effects:

[0056] The novel inlet valve and water heater of this utility model, by setting a rotatable valve core 2 in the inlet channel, and by using the connection between the through hole on the valve core 2 and the first or second outlet channel, can control the opening or closing of the first or second outlet channel. Compared with the traditional control using two solenoid valves, it is not only simple in structure, but also has a lower cost.

[0057] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
