[0002] Water heaters usually use anti-electricity walls to increase internal water resistance. When the water heater leaks electricity, the voltage can be reduced to a safe voltage range for the human body through water resistance. The connector of the anti-electricity wall is connected to the inner tank of the water heater. In order to prevent water leakage at the connection between the anti-electricity wall and the water heater, the prior art reduces the risk of water leakage by setting a sealing structure at the connection. However, water leakage still occurs during actual use.
[0003] The water heater in the prior art cannot monitor the water leakage at the connection between the electric-proof wall and the water heater. If the user fails to find the water leakage in the water heater in time, it will lead to waste of water resources and property loss, and even the risk of electric shock. Utility Model Content

[0034] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, an indirect connection through an intermediate medium, or the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0035] like Figure 1-Figure 3 As shown, this embodiment provides an anti-electricity wall, including a shell 1 and a detection component 3, each of the two ends of the shell 1 is provided with a joint, one of which is a first joint 21 for connecting to the inner tank, and the other joint is a second joint 22 for grounding, the first joint 21 and the second joint 22 are both iron inserts, and the surface is electroplated with Dacromet, and the anti-electricity wall is used to isolate the current in the inner tank of the water heater caused by the leakage of the heating tube, and to prevent the harm to the showerer caused by the ground wire or the water pipe being charged. The outer wall of the shell 1 is provided with a water collection tank 12, and the opening of the water collection tank 12 is arranged toward the first joint 21. When the connection between the first joint 21 and the inner tank leaks, water enters from the opening and is stored in the water collection tank 12. The detection component 3 is arranged in the water collection tank 12, and the detection component 3 is used to detect whether there is water stored in the water collection tank 12, so as to facilitate the timely detection of water leakage, thereby effectively avoiding the loss of water resources and property caused by the leakage of the connection between the first joint 21 and the inner tank, and reducing the risk of electric shock.
[0036] Specifically, the shell 1 includes a baffle 11, which is arranged around the circumference of the shell 1 and forms a water collecting groove 12 with the outer wall of the shell 1. The end of the baffle 11 away from the first joint 21 is connected to the outer wall of the shell 1, and an opening is formed between the end of the baffle 11 close to the first joint 21 and the outer wall of the shell 1. When the outer diameter of the first joint 21 is slightly greater than or equal to the outer diameter of the shell 1, the water collecting groove 12 is formed by arranging the baffle 11 around the circumference of the shell 1 on the outer wall of the shell 1, so that the water at the connection between the first joint 21 and the inner tank flows into the water collecting groove 12 along the first joint 21 and the outer wall of the shell 1. In this embodiment, the baffle 11 and the shell 1 are arranged as an integral structure, and are injection molded by a plastic material.
[0037] Of course, in other embodiments, the outer diameter of the shell 1 can be set to be larger than the outer diameter of the first joint 21, and an annular groove can be opened on the end face of the shell 1 near the first joint 21 to form a water collecting tank 12, so that water at the connection between the first joint 21 and the inner tank can flow downward along the first joint 21 to the end face of the shell 1, and then gather in the water collecting tank 12. The detection component 3 is arranged in the water collecting tank 12 to detect whether water is stored in the water collecting tank 12, and a signal is sent to the water heater when water is stored in the water collecting tank 12.
[0038] Furthermore, the enclosure 11 is configured as a bowl-shaped structure. The water at the bottom of the water collecting tank 12 formed by the enclosure 11 of the bowl-shaped structure and the outer wall of the housing 1 is easy to gather, which is easier to detect by the detection component 3, and the detection sensitivity is higher. Of course, in other embodiments, the enclosure 11 can also be configured as other structures such as a cylinder.
[0039] In one embodiment, the detection assembly 3 includes a first conductor 32, a second conductor 33 and a terminal 31. The first conductor 32 and the second conductor 33 are arranged at intervals, and the first conductor 32 and the second conductor 33 are respectively electrically connected to the terminal 31, and the terminal 31 is used to connect the control board. When the first conductor 32 and the second conductor 33 are both in contact with the water in the water collection tank 12, the first conductor 32 and the second conductor 33 are connected to form a loop; when one of the first conductor 32 and the second conductor 33 is not in contact with the water in the water collection tank 12, the first conductor 32 and the second conductor 33 are disconnected.
[0040] It is understandable that when there is no water leakage, there is no water in the water collecting tank 12, there is no conductive medium between the first conductor 32 and the second conductor 33, and the first conductor 32 and the second conductor 33 are disconnected. When there is water leakage at the connection between the first joint 21 and the inner tank, water enters from the opening and is stored in the water collecting tank 12, and the water between the first conductor 32 and the second conductor 33 can connect the first conductor 32 and the second conductor 33.
[0041] In one embodiment, the first conductor 32 is connected to the 5V power supply terminal of the control board, and the second conductor 33 is connected to the detection port of the control board; when the first conductor 32 and the second conductor 33 are connected, the detection port receives a 5V voltage signal, which indicates that there is a water leak at the connection between the inner tank and the first connector 21. When the first conductor 32 and the second conductor 33 are disconnected, the detection port does not receive a 5V voltage signal, which indicates that there is no water leak at the connection between the inner tank and the first connector 21. It should be noted that the voltage after the first conductor 32 and the second conductor 33 are connected is 5V, and there is no risk of electric shock to the human body.
[0042] In one embodiment, the first conductor 32 and the second conductor 33 are spaced apart along the circumference of the housing 1, and the first conductor 32 and the second conductor 33 are both located at the bottom of the water collecting tank 12. With such an arrangement, there is a small amount of water at the bottom of the water collecting tank 12, and when the small amount of water is located between the first conductor 32 and the second conductor 33 and the first conductor 32 and the second conductor 33 are connected, the control board can receive a voltage signal.
[0043] However, in actual use, water droplets condensed on the water heater may fall into the water collection tank 12, causing the first conductor 32 and the second conductor 33 to be conductive. At this time, there is no water leakage at the connection between the first connector 21 and the inner tank, which may easily cause a false alarm.
[0044] In order to avoid false alarms caused by condensed water drops in the water heater, in one embodiment, the first conductor 32 and the second conductor 33 are arranged at intervals along the circumference of the enclosure 11, and the first conductor 32 and the second conductor 33 are both located at a preset height of the water collection tank 12. That is, when the water in the water collection tank 12 accumulates to the preset height, the first conductor 32 and the second conductor 33 can be conductive, and the control board can receive the voltage signal at this time, thereby effectively avoiding the occurrence of false alarms.
[0045] In one embodiment, the first conductor 32 and the second conductor 33 are arranged at intervals along the axial direction of the housing 1, the first conductor 32 is located at the bottom of the water collecting tank 12, and the second conductor 33 is located at a preset height of the water collecting tank 12. The first conductor 32 is arranged at the bottom of the water collecting tank 12, and the second conductor 33 is arranged at a preset height. When the water in the water collecting tank 12 gathers to the preset height and contacts the second conductor 33, the first conductor 32 and the second conductor 33 are connected, and the control board can receive a voltage signal at this time.
[0046] Regarding the preset height, those skilled in the art may set it according to actual conditions, and no specific limitation is made in this embodiment.
[0047] In one embodiment, the detection component 3 includes a water level sensor, which is arranged in the water collection tank 12 and is used to detect the height of the water in the water collection tank 12. This embodiment also provides a water heater, including an inner tank, a control panel and the above-mentioned anti-electrical wall, the first connector 21 is connected to the inner tank, and the detection component 3 is electrically connected to the control panel. That is, the wiring terminal 31 or the water level sensor is connected to the control panel, and when the first conductor 32 and the second conductor 33 are turned on or the water level sensor detects that there is water in the water collection tank 12, a signal will be sent to the control panel, and the control panel controls the relay of the electric heating tube to be disconnected.
[0048] In one embodiment, the water heater further comprises a display panel, which is electrically connected to the control panel and is used to display water leakage prompt information. After receiving the signal sent by the detection component 3, the control panel controls the display panel to display the water leakage prompt information.
[0049] In one embodiment, the water heater further includes an alarm, which is electrically connected to the control panel, and the control panel controls the alarm to sound an alarm after receiving the signal sent by the detection component 3. When the control panel controls the relay to disconnect, it can also control the display panel to display water leakage prompt information and / or the alarm to sound an alarm, so as to remind the user to repair as soon as possible, avoid causing greater waste of water resources and property losses, and promptly avoid the occurrence of electric shock hazards, thereby improving the safety of the water heater.
[0050] In the specific contents of the above-mentioned specific implementation methods, the various technical features can be combined in any non-contradictory manner. In order to make the description concise, not all possible combinations of the above-mentioned technical features are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0051] The specific contents of the above specific implementations only express several implementations of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
