Embodiment 1

[0028] Embodiment 1 of the present invention provides a gas water heater anti-backflow control method, such as figure 1 As shown, it specifically includes the following steps:

[0029] Step 1, judge whether the gas water heater is activated, if the gas water heater is not activated, proceed to step 2, otherwise proceed to step 3;

[0030] Step 2, the temperature measurement module 7 detects the temperature of the external environment in real time and transmits the temperature to the controller 5, and the controller 5 opens or closes the anti-backflow provided on the exhaust channel of the gas water heater according to the received temperature information. Module 4, specifically:

[0031] Step 2.1, the temperature measurement module 7 detects the external environment temperature in real time;

[0032] Step 2.2, the controller 5 judges whether the external ambient temperature is greater than the temperature threshold, if so, the controller 5 drives the baffle 42 through the co...

Embodiment 2

[0038] Embodiment 2 of the present invention provides a gas water heater with an anti-downdraft function, such as figure 2 As shown, it includes a gas water heater body 1, a burner 2, a fan assembly 3, an anti-downdraft module 4, a controller 5, a smoke collection hood 6, a temperature measurement module 7 and a gas proportional valve 8; the burner 2, the fan assembly The component 3, the anti-backflow module 4, the controller 5, the smoke collecting hood 6 and the gas proportional valve 8 are all arranged in the gas water heater body 1, and the anti-backwind module 4 is arranged on the smoke exhaust channel formed by the smoke collecting hood 6 , the anti-downwind module 4 , the temperature measurement module 7 and the gas proportional valve 8 are all connected to the controller 5 .

[0039] The anti-wind module 4 includes a motor 41 and a baffle 42, the baffle 42 is located on the smoke exhaust channel, and the motor 41 is connected to the baffle 42 to drive the baffle 42 t...

Embodiment 3

[0044] Embodiment 3 of the present invention provides a gas water heater with anti-downdraft function, such as image 3 As shown, the difference between it and Embodiment 2 is: the fan assembly 3 is arranged at the front end of the burner 2, and the air outlet of the fan assembly 3 communicates with the exhaust passage of the gas water heater.

[0045] This embodiment is a positive pressure combustion type gas water heater.

[0046] work process:

[0047] Determine whether the gas water heater is activated;

[0048] If the gas water heater does not start, then the temperature measurement module 7 detects the external environment temperature in real time; the controller 5 judges whether the external environment temperature is greater than the temperature threshold, if so, the controller 5 drives the baffle plate 42 by controlling the motor 41 to prevent falling The wind module 4 is in the open state, otherwise the controller 5 controls the anti-wind module 4 to be in the clos...

Abstract

The invention discloses an anti-downdraft control method for a gas water heater. The control method comprises the following steps that when the gas water heater is in a non-working state, a temperature measuring module detects the temperature of an external environment in real time and transmits the temperature to a controller, the controller opens or closes an anti-downdraft module arranged on anexhaust channel of the gas water heater according to the received temperature information. The invention further discloses the gas water heater with a downdraft prevention function. According to thecontrol method, the downdraft prevention module is arranged on the exhaust channel of the gas water heater, the temperature measuring module is installed in the environment of the gas water heater, and the controller controls the downdraft prevention module to be opened or closed according to the temperature detected by the temperature measuring module, so that normal work of the gas water heateris guaranteed.

Description

technical field [0001] The invention belongs to the technical field of gas water heaters, and in particular relates to a gas water heater anti-backflow control method and a gas water heater. Background technique [0002] Gas water heaters have become an indispensable kitchen appliance in modern families, and gas water heaters provide us with the water heaters we need in our lives. But in winter, especially in most of the northern countries, the temperature in winter is generally lower than 0°C. When the gas water heater is not working and the water system is filled with cold water, if the whole machine is installed on a cold balcony or the outside cold The backflow of the exhaust pipe of the water heater will cause the internal temperature of the water heater to drop suddenly, the pipe will freeze and expand, and the pipe will easily crack and leak, causing economic losses to the user. [0003] In order to prevent the external cold air from passing through the smoke exhaust...
