Description

Anti-freezing valve and water heater applying same

Technical Field

The utility model relates to a valve for a water heater, in particular to an anti-freezing valve and a water heater applying the anti-freezing valve.

Background

The gas water heater is communicated with the outdoor environment through the smoke exhaust pipe, and cold air easily enters the water heater along the smoke exhaust pipe when the outdoor temperature is lower than zero centigrade in cold winter, so that the weak part of a water path pipeline of the water heater is frozen and cracked, and most of the gas water heaters are additionally provided with the electric heating anti-freezing cracking device, so that a certain anti-freezing function is achieved. The electric heating anti-frost-crack device can normally start to work only when the water heater is in a power-on state, and the situation that the electric heating device cannot be started and a water heater pipeline is frost-cracked due to the fact that some users have the habit of pulling out a power plug of the water heater after using the water heater, or have power failure at home, or a newly-decorated house does not use power failure for a long time and the like can be caused. The water channel of the water heater is usually a normally open valve at the water inlet end and a normally closed valve at the water outlet end, so that if a user does not find that the water inlet valve is closed in time, the whole machine leaks water, and property loss and safety problems such as water soaking on the floor, electric leakage and the like are caused.

The first opening notch is deeper than the second opening notch, so that the first eccentric groove and the second eccentric groove are eccentrically arranged, and the opening and closing part of the water inlet or the water outlet can be positioned at a high position or a low position.

Furthermore, the opening and closing parts of the water inlet and the water outlet respectively comprise a blocking head and a connecting rod connected to the tail end of the blocking head and a connecting part between the first eccentric groove and the second eccentric groove.

Preferably, each of the connecting rods includes a first connector connected to the end of each of the blocking heads and a second connector capable of sliding relative to each of the connecting portions, and when the valve rod drives the rod body to rotate, only the first opening notch and the second opening notch bypass each connecting rod, so that the opening and closing member of the water inlet and the opening and closing member of the water outlet are located at a high position or a low position. Because first eccentric groove and second eccentric groove are "H" type, when the valve rod drove the body of rod and rotate, only can take place the respective open notch one and the open notch two of first eccentric groove and second eccentric groove, walk around respective connecting rod to make the switch spare of water inlet and the switch spare of outlet be located high level or low level.

In order to be able to easily switch the respective opening and closing members of the water inlet and the water outlet selectively between the open state and the closed state, it is preferable that the water inlet and the water outlet are arranged side by side.

In order to solve the second technical problem, the utility model further provides a water heater with the anti-freezing valve, which comprises a casing, and is characterized in that: the valve body is connected to the water inlet connector of the casing.

Compared with the prior art, the utility model has the advantages that: the water inlet, the water outlet and the water outlet are integrated on the valve body, and the switching piece linked with the valve rod is arranged, so that the switching of water supply and water discharge functions can be realized only by rotating the valve rod, and an implementation mode of the anti-freezing valve is provided for realizing the automatic control of the gas quick water heater.
