Abstract
The utility model discloses a scald prevention protector for a water heater. The utility model is characterized in that a vertically placed water storage barrel is provided. A water inlet on the bottom of the water storage barrel is connected between the heat exchanger of the water heater and the water inlet of the water heater; a water outlet on the top of the water storage barrel is connected with the hot water outlet pipe of the water heater; a floating plug whose specific gravity is larger than water is arranged in the water storage barrel. The mixing of the cold water in the water storage barrel and the hot water in the water heater is controlled by the gravitational force of the floating plug and the pressure of the tap water; when the water heater is used, if the water heater is continues to use after halted, the temperature of the hot water flowed out is controlled in a safe range; the scald caused by hot water can be avoid.
Description
The utility model relates to a kind of water heater anti-scald protective device.Be applicable to all kinds of water heaters.
Chinese patent literature is not found similar utility model by retrieval, finds no like product on the market yet and sells.
At present, the water heater of market sale in use has when continuing to use again after suspend using, and it is too high that institute goes out the hot water short time in water temperature, and the situation of hot water scald takes place easily.This is that the water that remains in the water heater heat exchanger absorbs the heat exchanger waste heat in a large number and formed the warm water because water heater suspends when using.The purpose of this utility model is to propose a kind of water heater anti-scald protective device; this device can make water heater in use; when continuing to use again after time-out uses; institute goes out the hot water water temperature and is controlled in the safe range; thereby avoid hot water to scald the generation of situation; and after the warm water drains excessively, can guarantee that still water heater normally uses.
The utility model is achieved in that vertically to be settled a water storage tube, the water inlet of water storage tube bottom is connected between water heater heat exchanger water inlet pipe and the water heater water intaking valve, the delivery port on water storage tube top is connected in the hot-water outlet pipe of water heater, the water storage tube is built-in with the floating plug of a proportion greater than water, and floating plug and water storage tube inwall leave the gap.
Below in conjunction with accompanying drawing an embodiment of the present utility model is explained in detail.
Fig. 1 is the structural representation of water heater anti-scald protective device.
The water storage tube (1) that an inwall is the garden tubular is vertically settled, the water inlet (2) of water storage tube bottom is connected between the water inlet pipe (3) and water heater water intaking valve (4) of water heater heat exchanger (8), the delivery port (5) on water storage tube top is connected in the hot-water outlet pipe (6) of water heater, the water storage tube is built-in with the spherical rubber floating plug (7) of a proportion greater than water, the inboard, top of water storage tube (1) is a hemisphere face shape, its spherical radius is identical with the radius of spherical rubber floating plug (7), and the diameter of spherical rubber floating plug (7) is less than the internal diameter of water storage tube (1).
When using water heater, open the water heater water intaking valve, running water is divided into two-way by behind the water intaking valve, and one the tunnel enters heat exchanger through the heat exchanger water inlet pipe, is flowed out by the hot-water outlet pipe then; Another road enters the water storage tube through the water inlet of water storage tube bottom, floating plug in the water storage tube is under water buoyancy and flow action, constantly rise, until being raised to water storage tube top water storage tube delivery port is sealed, at this moment, because the effect of tap water pressure in the water storage tube, floating plug continue sealing water storage tube delivery port, water heater is in normal operating conditions.Use water heater if suspend, close the water heater water intaking valve, the suffered tap water pressure of floating plug of sealing water storage tube delivery port is close to disappearance, floating plug is under the effect of gravity, sink down into the water storage tube bottom gradually, simultaneously, the water that remains in the heat exchanger absorbs the heat exchanger waste heat in a large number, heat up rapidly, formed the warm water.After this, if continue to use water heater, open the water heater water intaking valve, running water is divided into two-way by behind the water intaking valve, and one the tunnel enters heat exchanger through the heat exchanger water inlet pipe, and the warm water that crosses in the heat exchanger is flowed to the hot-water outlet pipe; Another road enters the water storage tube through the water inlet of water storage tube bottom, floating plug in the water storage tube is under water buoyancy and flow action, constantly rise, simultaneously, cold water in the water storage tube flows into the hot-water outlet pipe from water storage tube delivery port, constantly mix with the warm water that crosses that heat exchanger flows out, made the warm water be cooled to normal temperature range rapidly, thereby avoid hot water to scald the generation of situation, when floating plug rises to water storage tube top, and when continuing sealing water storage tube delivery port under the effect of tap water pressure in the water storage tube, the cold water that flows into the hot-water outlet pipe from the water storage tube is blocked, and water heater is in normal operating conditions.
The utility model is simple in structure, and is easy to manufacture, do not influence original performance of water heater and manipulates, and is fit to all kinds of water heaters supporting.
