Description

Technical Field

[0001] This utility model relates to the field of water heater technology, specifically to an integrated water supply device. Background Technology

[0002] Existing methods for preventing dry burning in electric water heaters include temperature probes, electrode water level detection, and electronic magnesium rod circuit detection. However, the temperature probe detection method requires the heating element to be activated to detect the temperature. If the inner tank is already dry-burning, opening the heating element at this time can damage the plastic parts inside the inner tank. The electrode water level detection method requires separate installation inside the inner tank, which necessitates resealing and increases the risk of leaks. The electronic magnesium rod circuit detection method requires the product to have an electronic magnesium rod function, which limits its application. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide an integrated water supply device that detects changes in water level by measuring the height difference between the liquid level and the horizontal height of the water outlet anti-electric shock wall inlet. The detection device outputs a corresponding signal to control the start and stop of the heating device based on the detected liquid level. The device does not require changes to the structure of the water outlet anti-electric shock wall and the inner tank, resulting in a simple overall structure. At the same time, it does not affect the sealing effect between the water outlet anti-electric shock wall and the inner pipe.

[0004] To solve the above-mentioned technical problems, the technical solution used in this utility model is as follows:

[0005] The present invention relates to an integrated water supply device, comprising an inner tank, an outlet anti-electric shock wall disposed within the inner tank, and a heating device; the heating device is used to heat the liquid stored in the inner tank; the horizontal height of the inlet of the outlet anti-electric shock wall is higher than the horizontal height of the top of the heating device; a detection device is provided in the outlet anti-electric shock wall, the detection device is signal-connected to the heating device, and the detection device is used to detect the liquid level in the inner tank.

[0006] Preferably, the water outlet anti-electric shock wall is a plastic water outlet anti-electric shock wall; the detection device includes a first conductive element and a second conductive element, with a gap between the first conductive element and the second conductive element, and the first conductive element and the second conductive element are connected to the inner tank and the detection circuit.

[0007] The detection circuit includes a resistor R2, a voltage divider resistor R1, a voltage divider resistor R3, a detection power supply, and a microcontroller. The resistor R2 is the water circuit resistance between the inner tank and the outlet anti-electric wall. The detection power supply is connected to one end of the resistor R2 through the voltage divider resistor R1, and the other end of the resistor R2 is connected to the microcontroller and grounded through the voltage divider resistor R3.

[0008] Preferably, the first conductive element and the second conductive element are distributed along the height direction of the water outlet anti-electric wall, and the second conductive element is disposed above the first conductive element.

[0009] Preferably, the second conductive element is an internally threaded insert, and the first conductive element is an externally threaded insert.

[0010] Preferably, the first conductive element is provided with a wiring terminal.

[0011] Preferably, the inner liner is also equipped with a water inlet anti-electric shock wall, which is used to replenish liquid to the inner liner.

[0012] Preferably, a pressure relief valve is provided at the water inlet of the anti-electric shock wall.

[0013] The advantages of this gearbox compared to existing technologies are mainly reflected in the following aspects: The liquid level is detected by a detection device. When the liquid level is higher than the horizontal height of the water outlet anti-electric shock wall inlet, liquid flows into the water outlet anti-electric shock wall, the detection device detects the liquid, and then controls the heating device to start. When the liquid level is lower than the horizontal height of the water outlet anti-electric shock wall inlet, liquid cannot flow into the water outlet anti-electric shock wall, the detection device cannot detect the liquid, and then controls the heating device to shut down. Simultaneously, placing the detection device within the water outlet anti-electric shock wall does not affect the sealing effect between the water outlet anti-electric shock wall and the inner pipe. Furthermore, the horizontal height of the water outlet anti-electric shock wall inlet is higher than the horizontal height of the top of the heating device. When the liquid level is lower than the horizontal height of the water outlet anti-electric shock wall inlet, the heating element stops heating, preventing dry burning damage caused by the heating element starting when the water level is lower than the horizontal height of the heating element.

[0014] Liquid is detected using a first and second conductive element. When liquid flows between the first and second conductive elements, the liquid energizes the detection circuit formed by the first and second conductive elements, the inner tank, and the detection circuit. The voltage output from the detection power supply is divided by voltage divider resistors R1 and R3, resulting in a voltage divider voltage across R3. When the microcontroller detects this voltage divider voltage across R3, the heating element starts heating. When no liquid flows between the first and second conductive elements, the detection circuit is broken, and there is no voltage divider voltage across R3. When the microcontroller does not detect the voltage divider voltage across R3, the heating element shuts off, stopping heating. The channel between the first and second conductive elements is controlled based on the height difference between the liquid level and the horizontal level of the water outlet anti-electric shock wall inlet, thus achieving accurate detection of liquid level changes.

[0015] By setting the internal threaded insert as the first conductive element and the external threaded insert as the second conductive element, and since the internal threaded insert is installed on the inner liner, when connecting the first conductive element, the second conductive element, the inner liner, and the detection circuit, a resistor R2 is connected to the inner liner and the first conductive element through a circuit. The structure of the outlet anti-electric shock wall itself, in conjunction with the resistor, enables liquid level detection and heating device control, resulting in a simple structure. Furthermore, the outlet anti-electric shock wall is made of plastic, ensuring insulation between the outlet anti-electric shock wall and the first conductive element, and between the outlet anti-electric shock wall and the second conductive element; the outlet anti-electric shock wall will not interfere with the conduction between the first and second conductive elements.

[0016] A pressure relief valve is installed to discharge liquid when the pressure in the inner tank increases. When the heating device malfunctions and cannot control the heating temperature, the liquid in the inner tank continues to vaporize, which in turn increases the pressure in the inner tank. The pressure relief valve discharges the liquid in the inner tank to reduce the pressure in the inner tank, and at the same time, it causes the liquid level to drop. Then, when the liquid level is lower than the horizontal height of the water outlet anti-electric shock wall inlet, the detection device outputs a signal to control the heating device to shut down.

[0017] This invention detects changes in liquid level by measuring the height difference between the liquid level and the horizontal height of the inlet of the anti-electric shock wall. The detection device outputs a corresponding signal to control the start and stop of the heating device based on the detected liquid level. The invention does not require changes to the structure of the anti-electric shock wall and the inner tank, resulting in a simple overall structure. It also does not affect the sealing effect between the anti-electric shock wall and the inner pipe. Attached Figure Description

Detailed Implementation

[0024] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand this utility model and implement it. However, the embodiments are not intended to limit this utility model. In this embodiment, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this utility model.

[0025] It should be noted that when one element is considered to be "connected" to another element, it can be directly connected to and integrated with the other element, or there may be an intervening element present. The terms "mounted," "one end," "the other end," and similar expressions used in this invention are for illustrative purposes only.

[0026] This embodiment provides an integrated water supply device, such as... Figure 1-4 As shown, it includes an inner tank 1, an inlet anti-electric shock wall 2 and an outlet anti-electric shock wall 3 disposed in the inner tank 1, and a heating device 4; the heating device 4 is used to heat the liquid stored in the inner tank 1; the inlet anti-electric shock wall 2 is used to replenish the liquid in the inner tank 1; and the outlet anti-electric shock wall 3 is used to output the liquid in the inner tank 1.

[0027] The horizontal height of the water outlet anti-electric shock wall inlet 31 is higher than the horizontal height of the top of the heating device 4; a detection device 5 is provided in the water outlet anti-electric shock wall 3, and the detection device 5 is connected to the heating device 4 by signal. The detection device 5 is used to detect the liquid level in the inner tank 1. In a preferred embodiment, the heating device 4 is an electric heating tube.

[0028] The liquid level is detected by the detection device 5. When the liquid level is higher than the horizontal height of the water outlet anti-electric shock wall inlet 31, liquid flows into the water outlet anti-electric shock wall 3, the detection device 5 detects the liquid, and then controls the heating device 4 to start. When the liquid level is lower than the horizontal height of the water outlet anti-electric shock wall inlet 31, liquid cannot flow into the water outlet anti-electric shock wall 3, the detection device 5 cannot detect the liquid, and then controls the heating device 4 to shut down. At the same time, the detection device 5 is placed in the water outlet anti-electric shock wall 3, which will not affect the sealing effect between the water outlet anti-electric shock wall 3 and the inner tube. Meanwhile, the horizontal height of the water outlet anti-electric shock wall inlet 31 is higher than the horizontal height of the top of the heating device 4. When the liquid level is lower than the horizontal height of the water outlet anti-electric shock wall inlet 31, the heating tube stops heating to avoid the heating tube starting when the water level is lower than the horizontal height of the heating tube, which would cause dry burning and damage.

[0029] The water outlet anti-electric shock wall 3 is a plastic water outlet anti-electric shock wall; the detection device 5 includes a first conductive element 51 and a second conductive element 52, with a gap between the first conductive element 51 and the second conductive element 52, and the first conductive element 51 and the second conductive element 52 are connected to the inner liner 1 and the detection circuit 6.

[0030] The detection circuit 6 includes a resistor R2, a voltage divider resistor R1, a voltage divider resistor R3, a detection power supply, and a microcontroller U1. The resistor R2 is the water circuit resistance between the inner tank 1 and the outlet anti-electric shock wall 3. The detection power supply is connected to one end of the resistor R2 through the voltage divider resistor R1, and the other end of the resistor R2 is connected to the microcontroller U1 and grounded through the voltage divider resistor R3. In this embodiment, the resistor R2 is connected to the I / O port of the microcontroller U1.

[0031] Liquid is detected by the first conductive element 51 and the second conductive element 52. When liquid flows between the first conductive element 51 and the second conductive element 52, the liquid energizes the detection circuit formed by the first conductive element 51, the second conductive element 52, the inner liner 1, and the detection circuit 6. The voltage output by the detection power supply is divided by voltage divider resistors R1 and R3, and a voltage divider voltage exists on voltage divider resistor R3. When the microcontroller U1 detects the voltage divider voltage on voltage divider resistor R3, the heating element starts heating. When no liquid flows between the first conductive element 51 and the second conductive element 52, the detection circuit formed by the first conductive element 51, the second conductive element 52, the inner liner 1, and the detection circuit 6 is broken, and there is no voltage divider voltage on voltage divider resistor R3. When the microcontroller U1 does not detect the voltage divider voltage on voltage divider resistor R3, the heating element is turned off and heating stops. Based on the height difference between the liquid level and the horizontal height of the water outlet anti-electric shock wall inlet 31, the channel between the first conductive element 51 and the second conductive element 52 is controlled to detect changes in liquid level, thus achieving good accuracy.

[0032] In a preferred embodiment, the first conductive element 51 and the second conductive element 52 are distributed along the height direction of the water outlet anti-electric wall 3, with the first conductive element 51 located near the water outlet 32 ​​of the water outlet anti-electric wall; and the second conductive element 52 located above the first conductive element 51.

[0033] In a preferred embodiment, the second conductive element 52 is an internally threaded insert, and the first conductive element 51 is an externally threaded insert. By setting the internally threaded insert as the first conductive element 51 and the externally threaded insert as the second conductive element 52, since the internally threaded insert is installed on the inner liner 1, the second conductive element 52 is connected and electrically conductive to the inner liner 1. When connecting the first conductive element 51, the second conductive element 52, the inner liner 1, and the detection circuit 6, the resistor R2 is connected to the inner liner 1 and the first conductive element 51 through a line. The structure of the water outlet anti-electric shock wall 3 and the resistor are used to realize liquid level detection and control of the heating device 4, which is simple in structure. At the same time, the water outlet anti-electric shock wall 3 is made of plastic, so the water outlet anti-electric shock wall 3 is insulated from the first conductive element 51 and from the second conductive element 52. The water outlet anti-electric shock wall 3 will not interfere with the conduction between the first conductive element 51 and the second conductive element 52.

[0034] In a preferred embodiment, the first conductive element 51 is provided with a terminal block 510; the terminal block 510 is used to connect a circuit.

[0035] In a preferred embodiment, a pressure relief valve 7 is provided at the inlet of the water inlet anti-electric shock wall 2. The pressure relief valve is used to discharge liquid when the pressure in the inner tank 1 increases; when the heating device 4 malfunctions and cannot control the heating temperature, the liquid in the inner tank 1 continues to vaporize, which in turn increases the pressure in the inner tank 1; the pressure relief valve discharges the liquid in the inner tank 1 to reduce the pressure in the inner tank 1, and at the same time, it causes the liquid level to drop; then when the liquid level is lower than the horizontal height of the outlet anti-electric shock wall inlet 31, the detection device 5 outputs a signal to control the heating device 4 to shut down.

[0036] This invention detects changes in liquid level by measuring the height difference between the liquid level and the horizontal height of the inlet 31 of the water outlet anti-electric shock wall. The detection device 5 outputs a corresponding signal to control the start and stop of the heating device 4. The structure of the water outlet anti-electric shock wall 3 and the inner tank 1 does not need to be changed, the overall structure is simple, and it does not affect the sealing effect between the water anti-electric shock wall and the inner pipe.
