As shown in Figure 1 and Figure 2, a kind of reduction water cut-off temperature-rising gas instantaneous water heater, comprising: water heater body 1, is mounted on
Heat exchanger 2 in the water heater body 1, and connect with the heat exchanger 2 into cold water pipe 3 and hot-water outlet pipe 4；Its
Be characterized in that, be equipped with and cut off the water pre- stream water admixing device 5 on the hot-water outlet pipe 4, the pre- stream water admixing device 5 of cutting off the water include: and
The scalable water tank 5-1 of hot-water outlet pipe connection, and connect with the scalable water tank 5-1, for described in controlling
The compressed spring 5-2 of scalable water tank 5-1 capacity.
Wherein, the pre- stream water admixing device 5 of cutting off the water is mounted in the water heater body 1, the scalable water tank 5-1
For plastic part, rubber parts or metalwork.
In the present embodiment, the preferably described scalable water tank 5-1 is more piece corrugated tube shape, in the scalable water tank 5-
1 one end is equipped with the intake-outlet 5-3 connecting with the hot-water outlet pipe 4, and the compressed spring 5-2 setting is in the scalable storage
The other end of water pot 5-1.In other embodiments, the scalable water tank can be set to the chamber of column chamber or other shapes
Body structure, is not limited to the present embodiment.
It is further preferred that the corresponding compressed spring 5-2 is equipped with boss 5-4, one end of the compressed spring 5-2 and institute
Scalable water tank 5-1 connection is stated, the other end of the compressed spring 5-2 is socketed on the boss 5-4.Pass through boss 5-
4 can protect compressed spring to be not compressed safety margins.
It particularly, is the installation convenient for the pre- stream water admixing device 5 of cutting off the water, the preferably described scalable water tank 5-1 setting
In a separate frame 5-5, connector corresponding with the intake-outlet 5-3 is equipped on the frame 5-5.The frame 5-
5 play support entirety simultaneously and protect scalable water tank 5-1.
When normal work, to give the dynamic pressure of scalable water tank 5-1 be zero to water outlet water flow, static pressure also very little, in compression bullet
Under the pretightning force of spring 5-2, scalable water tank 5-1 is pressed very thin, in not water stored state.
When user midway cuts off the water, pressure increases sharply in hot-water outlet pipe, and compressed spring 5-2 elastic force will be overcome scalable storage
Water pot 5-1 is full of water, realizes that pre- stream, pre- flow are equal to moisture storage capacity.At this moment it should rest in pipe and be added by heat exchanger waste heat
The water of heat, flowing in advance forward, and subsequent cold water is made to move a distance in advance, and to absorb heat-exchanger fin waste heat, drop
Low water cut-off temperature-rising.
Again when boiled water, static pressure is reduced, and the hydraulic pressure that compressed spring 5-2 pushes scalable water tank 5-1 to be stored goes out,
It is mixed with the water in hot-water outlet pipe 4, achievees the purpose that water mixing constant temperature.
When user's use finishes, pressure of supply water makes water full of scalable water tank 5-1, to press safely at compressed spring 5-2
Contracting state.
Performance evaluation
When ordinary user's water supply pressure power is P1, the pressure for pre- stream water admixing device interface of cutting off the water in use process is
P2, P2 mostly come from user's spray head and the local pressure along journey, and P1 is much larger than P2.Root is only needed when selecting compressed spring
According to the user using when hot-water outlet pipe's pressure and scalable water tank forced area may be selected by out the compression met the requirements
Spring；Or by testing whether directly measurement compressed spring meets the requirements, thus according to the suitable compression of hydraulic pressure selection is not had to
Spring.
To the design of gas instantaneous water heater cut off the water pre- stream water admixing device when, in fin heats region in water heater
Length of pipe be X meters (including side bridge piece), obtain to be added by fin waste heat in water heater according to its internal diameter of the pipeline
The water of heat is Q, and the minimum volume of scalable water tank is determined that according to this section of water Q.
It is provided in this embodiment it is a kind of reduce water cut-off temperature-rising gas instantaneous water heater, cut off the water pre- stream water admixing device completely by
Hydraulic pressure starting, response is immediately and stability is good, this body structure makes manufacturing cost low, and durability is strong.
From the foregoing description of structures and principles it should be understood by those skilled in the art that, the utility model
It is not limited to above-mentioned specific embodiment, it is equal using the improvement of techniques well known and substitution on the basis of the utility model
The protection scope of the utility model is fallen in, the protection scope of the utility model should be limited by each claim and its equivalent
It.The part not illustrated in specific embodiment is the prior art or common knowledge.
