A dry burning prevention alarm device for flue gas water heater

Abstract

This application relates to the field of flue-type water heater technology, and more particularly to a flue-type gas water heater anti-dry-burning alarm device. To solve the problem of anti-dry-burning failure when the self-priming solenoid valve fails to reset after power loss, the device includes a housing, with an installation assembly inside the housing. This anti-dry-burning alarm device is installed on the surface of the self-priming solenoid valve of the flue-type gas water heater. Through the cooperation of the installation assembly, a first wire, and a second wire, it is installed with the water heater. When the water heater experiences dry burning due to the solenoid valve not closing after the water is turned off / the heater is shut off, the device's thermostat senses the high temperature and activates, causing the motor control transmission rod and eccentric block to rotate and vibrate. This vibration on the surface of the solenoid valve causes it to mechanically close, preventing dry burning after the water is turned off / the heater is shut off. A buzzer sounds as a warning. When the dry burning problem is resolved, the thermostat senses that the internal temperature of the water heater has returned to normal and activates, stopping the motor vibration and silencing the buzzer.

Description

Technical Field

[0001] This utility model relates to the technical field of flue-type water heaters, specifically to a flue-type gas water heater anti-dry-burning alarm device. Background Technology

[0002] A flue-type water heater is a type of water heater that heats water using gas. Its main feature is that it vents the exhaust gases produced during combustion outdoors through a flue, ensuring safety during use.

[0003] Currently, in the use of flue-type water heaters, the prevention of dry burning damage is achieved by cutting off the power to the solenoid valve to reset and close it. However, the current anti-dry burning solution still has some shortcomings in use. For example, the anti-dry burning solution fails when the self-priming solenoid valve fails to reset and close after a power outage, resulting in damage to the water heater.

[0004] Based on this, this utility model designs a flue-type gas water heater anti-dry-burning alarm device, which can mechanically reset and close the solenoid valve when it does not reset and close after power failure, so as to solve the problem. Utility Model Content

[0005] The purpose of this utility model is to provide a flue-type gas water heater anti-dry-burning alarm device to solve the problem of anti-dry-burning failure when the self-priming solenoid valve fails to reset after power failure in the above-mentioned background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flue-type gas water heater anti-dry-burning alarm device, comprising a housing, an installation component inside the housing, a vibration component inside the housing, a control component inside the housing, and a temperature control component below the housing.

[0007] Preferably, the control component includes a circuit board mounted on the inner wall of the housing, a buzzer is mounted on the control terminal of the circuit board, and two conductive plates are mounted on the control terminal of the circuit board, with a first wire sleeved on the outer surface of each conductive plate.

[0008] Preferably, the vibration assembly includes a carrier plate installed on the inner wall of the housing, a motor is fixedly installed on the upper surface of the carrier plate, a transmission rod is fixedly installed at the output end of the motor, and an eccentric block is fixedly installed at the left end of the transmission rod.

[0009] Preferably, the temperature control assembly includes a temperature controller disposed below the housing, and two conductive plates are fixedly installed at the output end of the temperature controller. A second wire is fixedly installed on the outer surface of one of the conductive plates, and the outer surface of the other conductive plate is fixedly installed with one of the first wires.

[0010] Preferably, the mounting assembly includes a baffle disposed inside the housing, two perforated mounting plates are fixedly mounted on the right side of the baffle, an insert plate is fixedly mounted on the right side of the baffle, and mounting holes are provided on both the front and back sides of the housing.

[0011] Preferably, the left side of the baffle is provided with two sets of clamping plates, and the right side of each clamping plate is fixedly installed with the right side of the baffle.

[0012] Preferably, two baffles are provided above and below the insert plate, and the two sets of baffles are in contact with the bottom surface and the top surface of the insert plate, respectively.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The anti-dry-burning alarm device is installed on the surface of the self-priming solenoid valve of the flue-type gas water heater. It is connected to the water heater through the cooperation of the device installation components, the first wire and the second wire. When the water heater is turned off / off and dry-burning occurs due to the solenoid valve not closing, the device thermostat senses the high temperature and activates, causing the motor control transmission rod and eccentric block to rotate and vibrate. By vibrating the surface of the solenoid valve, the solenoid valve is mechanically closed, preventing dry-burning after the water heater is turned off / off. At the same time, the buzzer sounds an alarm. When the dry-burning is resolved by the solenoid valve malfunction, the device thermostat senses that the internal temperature of the water heater has returned to normal and activates, causing the motor to stop vibrating and the buzzer to stop sounding.

Through the cooperation of the motor 502 and the transmission rod 503, power can be provided to the eccentric block 504, enabling the eccentric block 504 to rotate at high speed and generate vibration force.

[0021] Please see Figure 1The temperature control component 4 includes a thermostat 401 located below the housing 1. Two conductive plates 402 are fixedly installed at the output end of the thermostat 401. A second wire 403 is fixedly installed on the outer surface of one of the conductive plates 402, and a first wire 304 is fixedly installed on the outer surface of the other conductive plate 402.

The second wire 403 is connected to the power supply.

[0022] Please see Figure 4 The mounting component 2 includes a baffle 201 disposed inside the housing 1. Two perforated mounting plates 204 are fixedly mounted on the right side of the baffle 201. An insert plate 205 is fixedly mounted on the right side of the baffle 201. Mounting holes 202 are provided on both the front and back of the housing 1.

[0025] The implementation principle of the anti-dry-burning alarm device for a flue-type gas water heater in this application embodiment is as follows: When in use, the first wire 304 and the second wire 403 of the device are connected to the power supply. When the water heater is turned off / off and dry-burning occurs due to the solenoid valve not closing, the internal temperature of the water heater changes. Subsequently, the temperature is sensed by the thermostat 401. When the temperature reaches the set value, it activates and controls the motor 502 to work. The motor 502 drives the transmission rod 503 to rotate, which in turn drives the eccentric block 504 to rotate and generate vibration force. The vibration force generated by the eccentric block 504 mechanically closes the self-priming solenoid valve. At the same time, the circuit board 301 controls the buzzer 302 to work to alert people in the vicinity.
