Description

A special shower for gas water heater

technical field

The utility model relates to the field of constant temperature showers, in particular to a special constant temperature shower for gas water heaters.

Background technique

At present, the working principle of the water-vapor linkage valve of the gas water heater is realized through a mechanical structure. When there is water flow through, the valve will open, thereby driving the push rod on the valve to move to push the gas valve. When the flow of water is greater, The greater the valve opening volume, the greater the gas output.

Generally, the thermostatic valve used for gas water heaters needs to gradually reduce the hot water opening of the valve core when the temperature is lowered, resulting in a decrease in the hot water output of the gas water heater; when the hot water output of the gas water heater decreases Hours, due to the action of the water vapor linkage valve of the gas water heater, the gas flow is also decreasing; when the hot water output is less than the flow value set by the gas water heater for ignition demand, the gas will be turned off. When the hot water port of the spool is fully closed, the flow rate of the hot water outlet of the gas water heater is zero. Due to the effect of the water vapor linkage valve, when no water passes through, the gas valve is closed, and the gas water heater cannot provide gas, and the gas water heater cannot ignition. When the hot water outlet increases, the flow rate increases, and the gas volume also increases due to the water vapor linkage valve of the gas water heater. When the flow rate reaches the preset gas ignition flow value, the gas can be re-ignited.

From the above, it can be seen that the thermostatic valve used for gas water heaters tends to cause the flow of hot water to become smaller during temperature adjustment, resulting in repeated flameout and ignition problems in gas water heaters; gas water heaters have repeated flameouts and ignitions when the flow rate is small, resulting in intermittent cold and hot water. phenomenon, very inconvenient.

Start the flow. The spool body can also be realized by other structures in the prior art. The adjustment valve core 90 can also be set to two gears, namely summer gear and winter gear, and the corresponding auxiliary cold water channel 15 is in an open state and a closed state.

The specific working principle is as follows:

Cold water enters the cold water channel 14 through the cold water inlet 12 , while hot water enters the hot water channel 13 through the hot water inlet 11 . In the thermostatic spool, the cold water in the cold water channel 14 is mixed with hot water, and the first-level constant temperature water is output to the mixed water outlet 82. Because the outlet water temperature is controlled within a certain range (for example, 38-50°C), the outlet water temperature range , the water intake of the hot water inlet 11 is greater than the flow required for ignition set by the gas water heater, then the gas water heater will not be turned off.

When the adjustment handle 93 makes the adjustment valve core 90 in the summer gear, its water outlet 92 is in an open state, and the cold water of the cold water passage 14 connected to it flows in through the water inlet 91, flows out from the water outlet 92 to the auxiliary cold water passage 15, and reaches The auxiliary water inlet, after being accelerated by the acceleration hole 84, enters the auxiliary mixing water chamber 81 and mixes with the first-level constant temperature water from the mixing water outlet 82 to cool down to obtain the second-level constant temperature water, and promotes its flow rate to become faster, then the gas water heater The flow of hot water is also increased, and the secondary constant temperature water flows into the constant temperature water channel 16, and is output from the upper water outlet 17 or the lower water outlet 18 through the water diversion valve 100, so as to ensure that the user takes a cold shower.

When adjusting the handle 93 so that the regulating valve core 90 is in the winter gear, its water outlet 92 is in a closed state, and the cold water of the cold water channel 14 connected to it cannot flow in through the water inlet 91, and the first-stage constant temperature water of the mixed water outlet 82 is directly It is output to the constant temperature water channel 16 through the auxiliary mixing water chamber 81, and is output from the upper water outlet 17 or the lower water outlet 18 through the water diversion valve 100 to ensure that the user takes a hot bath.

Embodiment two

Referring to Figures 9-15, a special shower for gas water heaters, the main structure of which is the same as that of Embodiment 1, the difference is that the regulating spool 90 adopts a button spool, is installed in the cold water channel 14, and is provided with a water inlet 91, Water outlet 92, switching assembly and control piece. Its water inlet 91 communicates with the cold water channel 14 , and the water outlet 92 communicates with the auxiliary cold water channel 15 . The control part adopts a button, and the switch assembly is provided with a piston part 96, and a locking structure is also provided between the piston part 96 and the button, and the locking structure utilizes a bevel fit to lock or unlock the position of the piston part 96. By pressing the button, the piston member 96 is driven to open or block the water outlet, so as to control the connection between the auxiliary cold water channel 15 and the cold water channel 14 .

The specific working principle is as follows:

Cold water enters the cold water channel 14 through the cold water inlet 12 , while hot water enters the hot water channel 13 through the hot water inlet 11 . In the thermostatic spool, the cold water in the cold water channel 14 is mixed with hot water, and the first-level constant temperature water is output to the mixed water outlet 82. Because the outlet water temperature is controlled within a certain range (for example, 38-50°C), the outlet water temperature range , the water intake of the hot water inlet 11 is greater than the flow required for ignition set by the gas water heater, then the gas water heater will not be turned off.

When the button is pressed to make the adjustment valve core 90 in the summer position, its water outlet 92 is in an open state, and the cold water in the cold water channel 14 connected to it flows in through the water inlet 91, flows out from the water outlet 92 to the auxiliary cold water channel 15, and reaches the auxiliary cold water channel 15. The water inlet, after being accelerated by the acceleration hole 84, enters the auxiliary mixing water chamber 81 and mixes with the first-level constant temperature water from the mixing outlet 82 to cool down to obtain the second-level constant temperature water, and promotes its flow speed to become faster, then the gas water heater The flow of hot water is also increased, and the secondary constant temperature water flows into the constant temperature water channel 16, and is output from the upper water outlet 17 or the lower water outlet 18 through the water diversion valve 100, so as to ensure that the user takes a cold shower.

When the button is pressed to make the regulating valve core 90 in the winter gear, its water outlet 92 is blocked by the piston member 96 and is in a closed state, and the cold water of the cold water channel 14 connected with it cannot flow in through the water inlet 91, and the water outlet 82 of the mixing The first-level constant temperature water is directly output to the constant temperature water channel 16 through the auxiliary mixing water chamber 81, and then output from the upper water outlet 17 or the lower water outlet 18 through the water diversion valve 100 to ensure that the user takes a hot bath.

The above is only a specific embodiment of the utility model, but the design concept of the utility model is not limited thereto, and any non-substantial modification of the utility model by using this concept should be an act of violating the protection scope of the utility model.
