[0002] Electric water heaters are water heaters that use electricity as energy for heating. Electric water heaters can be divided into three types according to the heating power: storage type, instant type and rapid heating type.

[0003] The electric water heater of the related technology usually has an anti-dry-burning structure, which usually includes an over-temperature thermostat. The over-temperature thermostat is arranged in the tank body. When the water heater is dry-burned, the sensor of the over-temperature thermostat will detect a sharp rise in temperature. At this time, the over-temperature thermostat can display the temperature on the display panel of the electric water heater and can automatically trip and cut off the power.

[0004] However, there is a certain distance between the sensor and the heating device, which causes a delay in the electric water heater's acquisition of dry-burning information and an inability to actively predict the occurrence of dry-burning. There is a time difference between the actual discovery of dry-burning and the detection and termination of dry-burning. When the power is cut off by the circuit breaker, the dry-burning has lasted for several minutes, causing irreversible damage to the insulation layer of the electric water heater, thereby affecting the insulation performance of the electric water heater during use.

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the utility model described here can be implemented in an order other than those illustrated or described here, for example.

[0033] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0034] The electric water heater of the related technology usually has an anti-dry-burning structure, which usually includes an over-temperature thermostat. The over-temperature thermostat is arranged in the tank body. When the water heater is dry-burned, the sensor of the over-temperature thermostat will detect a sharp rise in temperature. At this time, the over-temperature thermostat can display the temperature on the display panel of the electric water heater and can automatically trip and cut off the power.

[0035] However, there is a certain distance between the sensor and the heating device, which causes a delay in the electric water heater's acquisition of dry-burning information and makes it impossible to actively predict the occurrence of dry-burning. There is a time difference between the actual discovery of dry-burning and the detection and termination of dry-burning. When the power is cut off by the circuit breaker, the dry-burning has lasted for several minutes, causing irreversible damage to the insulation layer of the electric water heater, thereby affecting the insulation performance of the electric water heater during use; and the over-temperature thermostat is set. When dry-burning occurs, the over-temperature thermostat needs to be reset. The over-temperature thermostat is usually set inside the tank body, so the tank body needs to be disassembled to reset the over-temperature thermostat. These operations are dangerous to users and generally require after-sales personnel to come to the site for repairs.

[0036] In order to solve the above technical problems, the present application provides a water heater anti-dry-burning structure and a water heater, which detects the pressure inside the tank body when the water level is at different positions in the tank body through a pressure sensor, thereby realizing the detection of the water level in the tank body. When the water level in the tank body is lower than the preset water level, at this time, because the pressure sensor is electrically connected to the display panel, the pressure sensor can prompt the user through the display panel that the tank body is in a water shortage state, thereby prompting the user that there is no need to turn on the heating device, and when the tank body is in a water shortage state, the heating switch can disconnect the electrical connection with the heating device, thereby failing to issue a heating command to the heating switch, so that the electric water heater can actively prevent the heating switch from being turned on to realize dry-burning prevention when there is not enough water in the tank body, and there is no need to wait for the electric water heater to dry-burn for a period of time before realizing the control. The cutting off of the heating device enables the electric water heater to obtain and actively predict the dry-burning information in the tank body in a timely manner, thereby realizing the active dry-burning prevention of the water heater, thereby preventing the water heater from being dry-burned and affecting the thermal insulation performance of the insulation layer, indirectly improving the safety of the electric water heater, and eliminating the need to manually reset the over-temperature thermostat of the related technology after dry-burning, so that the user does not need to contact after-sales service for repair after dry-burning occurs, thereby reducing the repair cost and difficulty of the electric water heater; when the water level in the tank body is equal to or greater than the preset water level, the pressure sensor can prompt the user through the display panel that the tank body is in a water state, thereby prompting the user to turn on the heating device through the heating switch to ensure normal heating when there is water in the tank body, thereby improving the use effect of the water heater.

[0037] Combination Figures 1 to 4 On the one hand, the present application provides a water heater anti-dry-burning structure, including a detection mechanism 100 and a heating switch 200. The detection mechanism 100 is used to be electrically connected to the display panel 300 of the water heater. The detection mechanism 100 is configured to detect the water level in the tank body 400 of the water heater, and when the water level in the tank body 400 is less than a preset water level, the display panel 300 prompts the user that the tank body 400 is in a water shortage state; when the water level in the tank body 400 is equal to or greater than the preset water level, the display panel 300 prompts the user that the tank body 400 is in a water-containing state; the heating switch 200 is electrically connected to the detection mechanism 100, and the heating switch 200 is used to be electrically connected to the heating device 500 of the water heater. The heating switch 200 is configured to disconnect the electrical connection with the heating device 500 when the tank body 400 is in a water shortage state.

[0038] In this embodiment, a controller is also included, and the controller is electrically connected to the detection mechanism 100 and the display panel 300. The controller can receive signals from the detection mechanism 100, thereby controlling the display panel 300 to display different contents; the display panel 300 is a display screen for the water heater to display temperature or other data; in this embodiment, the water shortage state and the water state can be displayed in a textual manner, for example, water or water shortage is directly displayed in text on the display panel 300, and patterns of different colors can also be used to prompt the user. For example, a red circle is displayed on the display panel 300 in the water shortage state, and a green circle is displayed on the display panel 300 in the water shortage state.

[0039] The water level in the tank body 400 can be detected by the detection mechanism 100. When the water level in the tank body 400 is lower than the preset water level, the detection mechanism 100 can prompt the user through the display panel 300 that the tank body 400 is in a water shortage state, thereby prompting the user that there is no need to turn on the heating device 500. When the tank body 400 is in a water shortage state, the heating switch 200 can disconnect the electrical connection with the heating device 500, so that the heating command of the heating switch 200 cannot be performed, so that the electric water heater can actively prevent the heating switch 200 from being turned on to prevent dry burning when there is insufficient water in the tank body 400. There is no need to wait for the electric water heater to dry burn for a period of time before cutting off the heating device 500, so that the electric water heater can timely obtain the dry burning information in the tank body 400 and actively predict , realizing active dry-burn prevention of the water heater, thereby preventing the water heater from being dry-burned and affecting the thermal insulation performance of the thermal insulation layer, indirectly improving the safety of the electric water heater, and there is no need to manually reset the over-temperature thermostat of the related technology after dry-burning, so that the user does not need to contact after-sales for repair after dry-burning occurs, thereby reducing the repair cost and difficulty of the electric water heater; the water level in the tank body 400 can be detected by the detection mechanism 100. When the water level in the tank body 400 is equal to or greater than the preset water level, the detection mechanism 100 can prompt the user through the display panel 300 that the tank body 400 is in a water state, thereby prompting the user to turn on the heating device 500 through the heating switch 200 to ensure that the tank body 400 is heated normally when there is water, thereby improving the use effect of the water heater.

[0040] Combination Figures 1 to 4 The heating switch 200 is used to be set on the display panel 300, and the heating switch 200 is electrically connected to the display panel 300; in other embodiments, the heating switch 200 can also be set separately at other positions of the tank body 400, such as on the outer wall of the tank body 400, or the heating switch 200 can be set on a panel used for wireless control of the water heater.

[0041] By adopting the above technical solution, the heating switch 200 is arranged on the display panel 300 , so that it is convenient for the user to operate the heating switch 200 when the user knows the state of the body 400 on the display panel 300 .

[0042] Combination Figures 1 to 4 , the heating switch 200 includes a touch button.

[0043] In this embodiment, the touch button is integrated on the display board 300. The touch button can be arranged on the display board 300 in the form of text. For example, the word "heating" is displayed on the display board 300. The color of the word "heating" can be changed to prompt the user whether there is water in the gallbladder body 400. For example, when the gallbladder body 400 is in a water-deficient state, the word "heating" can be displayed in red. When the gallbladder body 400 is in a water-containing state, the word "heating" can be displayed in green. When the user operates the touch button, the touch switch can be turned on and off directly by touching. When the user operates the touch button, the color of the touch button can be changed to prompt The user can touch the on / off state of the button, or prompt the user of the on / off state of the button by changing the text on the button. For example, when the user presses the button to turn on the heating device 500, the word "heating" can be changed to an on state. When the user presses the button again, the word "heating" can be changed to a off state. When the tank body 400 is short of water and the user presses the button, the word "heating" can be changed to a "please fill with water" state. In other embodiments, the button can be changed to a mechanical button, such as a push button switch or a knob switch. The touch switch can also be integrated on a panel for wirelessly controlling the water heater.

[0044] By adopting the above technical solution and setting a touch button, the heating switch 200 and the display panel 300 can be integrated together, thereby facilitating the production of the display panel 300 and the heating switch 200, and the setting of the touch button facilitates cutting off the electrical connection between the touch button and the heating device 500 through the display panel 300.

[0045] Combination Figures 1 to 4 The detection mechanism 100 is one of a pressure sensor, a photoelectric liquid level sensor, an ultrasonic liquid level sensor, a capacitive liquid level sensor and a float liquid level sensor.

[0046] In this embodiment, the detection mechanism 100 is configured as a pressure sensor; a pressure sensor is a device or apparatus that can sense a pressure signal and convert the pressure signal into a usable output electrical signal according to a certain rule. A pressure sensor is usually composed of a pressure sensitive element and a signal processing unit. According to different test pressure types, pressure sensors can be divided into gauge pressure sensors, differential pressure sensors, and absolute pressure sensors. Pressure sensors are the most commonly used sensors in industrial practice and are widely used in various industrial automatic control environments.

[0047] By adopting the above technical solution, the pressure inside the bile body 400 is detected by a pressure sensor. When the water in the bile body 400 increases, the pressure inside the bile body 400 will also increase, so that the pressure sensor can detect the water level according to the change of the internal pressure of the bile body 400. The setting of the pressure sensor has the advantages of light weight, reliable operation, simple structure, high signal-to-noise ratio, high sensitivity and signal bandwidth, which improves the detection accuracy of the water level in the bile body 400.

[0048] Combination Figures 1 to 4 The detection mechanism 100 is used to be passed through and fixedly connected to the gallbladder body 400, and one end of the detection mechanism 100 extends to be set in the gallbladder body 400.

[0049] In this embodiment, the gallbladder body 400 includes an outer gallbladder 410 and an inner gallbladder 420 arranged inside the outer gallbladder 410. Both the outer gallbladder 410 and the inner gallbladder 420 are provided with mounting holes 430. The pressure sensor is inserted into the mounting hole 430, and one end of the pressure sensor is located inside the inner gallbladder 420, and the other end is located outside the outer gallbladder 410. The pressure sensor can be fixed in the mounting hole 430 by welding or gluing, or the pressure sensor can be fixed to the gallbladder body 400 by bolting.

[0050] In other embodiments, the pressure sensor can be integrated into the temperature measuring tube of the water heater, or the pressure sensor can be integrated into the flange used to install the heating device 500, or the pressure sensor can be integrated into the insulating water pipe of the water heater. The installation position of the pressure sensor can be adaptively adjusted as needed.

[0051] By adopting the above technical solution, by passing the detection mechanism 100 through and fixedly connected to the bile body 400, it is convenient to install the detection mechanism 100 separately. When the detection mechanism 100 is damaged, it is convenient to directly replace the detection mechanism 100, thereby improving the use effect of the detection mechanism 100; by extending one end of the detection mechanism 100 into the bile body 400, the detection mechanism 100 can detect the water level in the bile body 400.

[0052] Combination Figures 1 to 4 The end of the detection mechanism 100 located outside the body 400 is located at the position where the display panel 300 is located.

[0053] In this embodiment, the end of the pressure sensor located outside the gallbladder body 400 is located at the position where the display panel 300 is located, the bottom of the outer gallbladder 410 has a display cover 700, the display panel 300 is located inside the display cover 700, and the end of the pressure sensor located outside the gallbladder body 400 is located inside the display cover 700.

[0054] By adopting the above technical solution, by setting the detection mechanism 100 at the position where the display panel 300 is located, the display cover 700 of the water heater can shield and protect the detection mechanism 100, preventing the detection mechanism 100 from being exposed to the outside and damaged, and by shortening the distance between the detection mechanism 100 and the display panel 300, it is convenient to electrically connect the detection mechanism 100 and the display panel 300.

[0055] Combination Figures 1 to 4 The detection mechanism 100 has a signal line 110, and the signal line 110 is electrically connected to the display panel 300; in the present embodiment, one end of the signal line 110 is arranged on the pressure sensor, and the other end extends to the position where the display panel 300 is located, and the signal line 110 is partially located between the outer liner 410 and the inner liner 420 of the liner body 400, and partially located outside the outer liner 410 and located inside the display cover 700.

[0056] Combination Figures 1 to 4 The water heater anti-dry burning structure also includes a seal 600, which is used to seal the gap between the detection mechanism 100 and the tank body 400; in this embodiment, the seal 600 is used to seal the gap between the inner wall of the mounting hole 430 and the pressure sensor.

[0057] By adopting the above technical solution, the gap between the detection mechanism 100 and the gallbladder body 400 can be sealed by the setting of the sealing member 600, thereby preventing the water in the gallbladder body 400 from flowing out along the gap between the detection mechanism 100 and the gallbladder body 400, and preventing the water vapor in the bathroom from entering the gallbladder body 400 along the gap between the detection mechanism 100 and the gallbladder body 400 when the water heater is placed in a bathroom for use, thereby indirectly improving the use effect of the gallbladder body 400.

[0058] Combination Figures 1 to 4 The sealing member 600 includes a sealing ring, which is sleeved on the detection mechanism 100 and is used to abut against the outer wall of the gallbladder body 400. In the present embodiment, the sealing ring is made of rubber material. By interference-fitting the sealing ring between the pressure sensor and the mounting hole 430, the sealing ring can achieve sealing between the pressure sensor and the mounting hole 430.

[0059] By adopting the above technical solution, the detection mechanism 100 can abut the sealing ring against the gallbladder body 400, so that the sealing ring can seal the gap between the detection mechanism 100 and the gallbladder body 400. The setting of the sealing ring has a simple structure, improves the sealing effect between the detection mechanism 100 and the gallbladder body 400, and the setting of the sealing ring facilitates replacement of the sealing ring when it is damaged.

[0060] In other embodiments, sealant may also be used to seal the gap between the detection mechanism 100 and the mounting hole 430 .

[0061] On the other hand, the present application provides a water heater, comprising a water heater body and a water heater anti-dry-burning structure of any of the above-mentioned embodiments arranged on the water heater body.

[0062] Among them, the specific structure of the water heater anti-dry burning structure has been described in detail in the above embodiments, and will not be repeated here.

[0063] The water heater body includes a tank body 400; the pressure sensor is used to detect the pressure inside the tank body 400 when the water level is at different positions in the tank body 400, thereby realizing the detection of the water level in the tank body 400. When the water level in the tank body 400 is lower than the preset water level, the pressure sensor is electrically connected to the display panel 300, so that the pressure sensor can prompt the user through the display panel 300 that the tank body 400 is in a water shortage state, thereby prompting the user that there is no need to turn on the heating device 500, and when the tank body 400 is in a water shortage state, the heating switch 200 can disconnect the electrical connection with the heating device 500, thereby failing to perform the heating command of the heating switch 200, so that the electric water heater can actively prevent the heating switch 200 from being turned on to prevent dry burning when there is insufficient water in the tank body 400, and there is no need to wait for the electric water heater to dry burn for a period of time before it can be turned on. The cutting off of the heating device 500 enables the electric water heater to timely obtain and actively predict the dry-burning information in the tank body 400, thereby realizing the active dry-burning prevention of the water heater, thereby preventing the water heater from being dry-burned and affecting the thermal insulation performance of the insulation layer, indirectly improving the safety of the use of the electric water heater, and eliminating the need to manually reset the over-temperature thermostat of the related technology after dry-burning, so that the user does not need to contact after-sales service for repair after dry-burning occurs, thereby reducing the repair cost and difficulty of the electric water heater; when the water level in the tank body 400 is equal to or greater than the preset water level, the pressure sensor can prompt the user through the display panel 300 that the tank body 400 is in a water state, thereby prompting the user to turn on the heating device 500 through the heating switch 200 to ensure that the tank body 400 is normally heated when there is water, thereby improving the use effect of the water heater.
