SPECIFIC IMPLEMENTATION MANNERS

[0039] The following specifically illustrates the present utility model in combination with embodiments:

[0040] Embodiment 1:

[0041] A water circuit system, used in a gas water heater, as shown in Figure 1 to Figure 4 shown. The water circuit system is disposed inside the housing 1. And the water circuit system mainly includes a water supply pipeline 2 for water circulation. The water supply pipeline 2 is a single pipe or formed by connecting several pipes end to end, as shown in Figure 2 and Figure 3As shown in the figure, it includes: a water inlet 2a at one end of the water supply pipe 2, a water outlet 2b at the other end of the water supply pipe 2, and a flow channel located inside the water supply pipe 2 and connecting the water inlet 2a and the water outlet 2b.

[0042] Among them, when the water supply pipe 2 is placed in the housing 1 of the gas water heater, generally a part of the pipe is coiled around the heat exchanger 3 inside the housing 1. When the water heater works, gas burns in the heat exchanger 3 to form high-temperature flue gas. Cold water enters the water supply pipe 2 from the water inlet 2a of the water supply pipe 2. When flowing through the part of the pipe coiled around the heat exchanger 3, the high-temperature flue gas formed by the heat exchanger 3 heats the water to form hot water, and the hot water is discharged outward from the water outlet 2b of the water supply pipe 2.

[0043] In order to monitor a certain state of the water in the water supply pipe 2, a sensor 4 is usually provided in the water supply pipe 2. For example: in order to be able to monitor the temperature of the water in the water supply pipe 2 in real time, the sensor 4 is a temperature sensor provided in the water supply pipe 2. The size of the sensor 4 is smaller than the aperture size of the flow channel to avoid the sensor 4 blocking the flow channel.

[0044] When the sensor 4 is placed in the water supply pipe 2 and there is a water flow flowing from the water inlet 2a to the water outlet 2b in the flow channel inside the water supply pipe 2, a part of the water flow will directly flow towards the sensor 4 and impact the sensor 4; another part of the water flow will flow out towards the water outlet 2b from the gap between the sensor 4 and the side wall of the flow channel without impacting the sensor 4.

[0045] Therefore, in order to protect the sensor 4 and slow down the impact of the water flow on it. As shown in the appendix Figure 3 In this embodiment, a baffle 5 is provided.

[0046] Specifically, as shown in the appendix Figure 3 The baffle 5 is configured to be located on one side of the sensor 4 (i.e., on the side of the sensor 4 facing the water inlet 2a in the extension path of the water supply pipe 2), and can block the water flow flowing towards the sensor 4 when there is a water flow flowing from the water inlet 2a to the water outlet 2b in the flow channel.

[0047] Among them, the size of the baffle 5 is smaller than the aperture size of the flow channel, so that there is a space for water to flow from the water inlet 2a to the water outlet 2b between the baffle 5 and the side wall of the flow channel, avoiding the sensor 4 blocking the flow channel, and the size of the baffle 5 is adapted to the size of the sensor 4 to be able to cover the sensor 4 well on the side of the sensor 4 facing the water inlet 2a.

[0048] In this way, the baffle 5 can block the water flow in the water supply pipeline 2, preventing the water flow that originally flowed towards the sensor 4 from directly impacting the sensor 4, so as to protect the sensor, reduce the impact of the water flow on the sensor 4, and improve the stability and service life of the sensor 4. After the water flow is blocked by the baffle 5, it will flow out towards the water outlet 2b from the gap between the baffle 5 and the side wall of the flow channel.

[0049] At this time, a number of flow holes 5.1 can be provided on the baffle 5, and the flow holes 5.1 form a channel for the water supply to flow from the water inlet 2a to the water outlet 2b. By providing the flow holes 5.1, the smoothness of the water flow can be improved, and the blocking effect of the baffle 5 on the water flow can be reduced; by providing the flow holes 5.1, part of the water flow can also pass through the baffle 5 and flow to the sensor 4, enabling the sensor 4 to better detect the water; moreover, the water flow flowing to the sensor 4 through the flow holes 5.1 has a smaller impact and is not likely to cause too much impact on the sensor 4.

[0050] Furthermore, considering that problems are likely to occur during the long-term use of the sensor 4. Therefore, in this embodiment, it is preferably to install the sensor in the detachable water tank body 2.2. By disassembling the water tank body 2.2, the sensor 4 can be more conveniently and easily disassembled from the water supply pipeline 2 for maintenance or replacement.

[0051] Specifically, as shown in the attached Figure 2 and attached Figure 3 figures, the water supply pipeline 2 in this embodiment includes: two water supply pipes 2.1 arranged at intervals, and a water tank body 2.2 that connects the two water supply pipes 2.1.

[0052] The water tank body 2.2 is detachably fixed between the two water supply pipes 2.1; moreover, the inside of the water tank body 2.2 is formed with a cavity: a water flow cavity 2.21 that connects the two water supply pipes 2.1 and accommodates the sensor 4. That is, when the water tank body 2.2 is installed between the two water supply pipes 2.1, the two water supply pipes 2.1 are connected through the water flow cavity 2.21.

[0053] Both the baffle 5 and the sensor 4 are fixedly accommodated in the water flow cavity 2.21.

[0054] Specifically, in this embodiment, as shown in the attached Figure 3 figures, one end of the baffle 5 is fixedly connected to the water tank body 2.2, and an accommodation section is formed at an interval between the other end and the first side wall 2.211 of the water flow cavity 2.21; the sensor 4 is accommodated in the accommodation section.

[0055] Moreover, the baffle 5 has a side surface facing away from the first side wall 2.211, and this side surface is preferably set as an arc surface, so that when the water flow passes through this side surface, it can flow more smoothly, reducing the possibility of eddy currents.

[0056] In this embodiment, the diameter of the water flow chamber 2.21 is preferably larger than the diameter of the water supply pipe 2.1. In this way, on the one hand, it enables the sensor to have a larger accommodation space; on the other hand, placing the sensor in the water flow chamber 2.21 with a larger diameter and larger capacity enables the sensor to sense a larger amount of hot water to obtain more accurate detection results.

[0057] Among them, the water tank body 2.2 can be detachably fixed between the two water supply pipes 2.1 through a variety of detachable connection structures. For example, the water tank body 2.2 can be detachably fixed between the two water supply pipes 2.1 through common threaded structures or pipe joints for pipes.

[0058] In this embodiment, it is preferably to adopt an insertion and buckling structure to detachably fix the water tank body 2.2 between the two water supply pipes 2.1, ensuring convenient disassembly and assembly while improving the connection stability.

[0059] Specifically, as shown in the attached Figure 3 to the attached Figure 4 shown:

[0060] In this embodiment, for each water supply pipe 2.1, an insertion pipe 2.22 is provided on the water tank body 2.2 that matches this water supply pipe 2.1. One end of the insertion pipe 2.22 is connected to the water flow chamber 2.21, and the other end is open for the water supply pipe 2.1 to be inserted. The water supply pipe 2.1 is inserted into the insertion pipe 2.22 and is connected to the water flow chamber 2.21.

[0061] That is, as shown in the attached Figure 3 to the attached Figure 4 shown, at the upper end of the water tank body 2.2, an insertion pipe 2.22 is provided that matches the upper water supply pipe 2.1 above. The upper water supply pipe 2.1 is inserted into the insertion pipe 2.22 at the upper end of the water tank body 2.2 and is connected to the water flow chamber 2.21. At the lower end of the water tank body 2.2, an insertion pipe 2.22 is provided that matches the lower water supply pipe 2.1 below. The lower water supply pipe 2.1 is inserted into the insertion pipe 2.22 at the lower end of the water tank body 2.2 and is connected to the water flow chamber 2.21. Thus, the two water supply pipes 2.1 are connected through the water flow chamber 2.21.

[0062] At the same time, any insertion pipe 2.22 and the water supply pipe 2.1 inserted into this insertion pipe 2.22 are detachably connected through a buckling structure, realizing the detachable fixation of the water tank body 2.2 between the two water supply pipes 2.1.

[0063] In this embodiment, as shown in the attachedFigure 3 To Attachment Figure 4 As shown, the buckle structure includes: a first flange 2.23 arranged on the outer periphery of the plug-in tube 2.22, a second flange 2.11 arranged on the outer periphery of the water supply pipe 2.1, and a detachable clip 2.3.

[0064] The first flange 2.23 is matched with the second flange 2.11, so that when the water supply pipe 2.1 is inserted into the plug-in pipe 2.22, the second flange 2.11 fits on the first flange 2.23. The clamp 2.3 is configured to restrict the first flange 2.23 and the second flange 2.11 from fitting together, so that the plug-in pipe 2.22 is detachably connected to the water supply pipe 2.1 inserted into the plug-in pipe 2.22.

[0065] Furthermore, as attached Figure 4 As shown, the clamp 2.3 in this embodiment includes: two clamps 2.31 respectively arranged on both sides of the water supply pipe 2.1, and a connecting arm 2.32 connecting the two clamps 2.31.

[0066] Each clamp 2.31 is provided with a clamping hole 2.33, and the first flange 2.23 and the second flange 2.11 that fit together are embedded in the clamping hole 2.33. Figure 2 and attached Figure 3 As shown in the figure, the first flange 2.23 and the second flange 2.11 are fitted together in a restricted manner. Moreover, the connecting arm 2.32 is elastic so that the clamp 2.3 can be disassembled by driving the connecting arm 2.32 to stretch and deform. That is, by bending the two clamps 2.31 outwards, the connecting arm 2.32 is driven to stretch, so that the first flange 2.23 and the second flange 2.11 are separated from the clamping hole 2.33, and the clamp 2.3 can be disassembled, so that the water supply pipe 2.1 can be pulled out from the plug pipe 2.22, and the water tank body 2.2 can be disassembled.

[0067] A seal 2.4 may be provided between the water supply pipe 2.1 and the inner wall of the water tank 2.2 to fill the gap between the water supply pipe 2.1 and the inner wall of the water tank 2.2. The seal 2.4 is preferably a sealing ring made of silicone or rubber, etc., which is filled in the gap between the water supply pipe 2.1 and the inner wall of the water tank 2.2 to achieve sealing.

[0068] Furthermore, the water flow chamber 2.21 is formed by surrounding a plurality of inner walls of the water tank body 2.2, and the plurality of inner walls form side walls of the water flow chamber 2.21; and, for a plurality of adjacent side walls that are not located in the same plane, edges and angles are formed between the adjacent side walls. In the present embodiment, the corners of the side walls of the water flow chamber 2.21 are formed in an arc shape by, for example, a rounding process, so that water can flow more smoothly in the water flow chamber 2.21, thereby reducing the possibility of eddy currents.

[0069] Furthermore, a plurality of reinforcing ribs 2.24 may be provided on the water tank body 2.2 to enhance the structural strength of the water tank body 2.2 and reduce the possibility of damage during disassembly and assembly.

[0073] On the above basis, a support member may be further provided inside the housing 1. The support member is fixed to the housing 1, and the water tank body 2.2 is detachably fixed to the support member, for example, by screws. At this time, the support member supports the water tank body 2.2 with a certain weight to improve the stability of the installation of the water tank body 2.2 and reduce the possibility of water leakage at the connection between the water tank body 2.2 and the water supply pipe 2.1.
