As shown in fig. 1, the instant water heater includes a heating element 1, a water inlet 2 and a water outlet 3 which are communicated with the heating element 1, a water outlet pipe 4 is arranged between the heating element 1 and the water outlet 3, the water outlet pipe 4 includes a reducing pipe 41 and a non-reducing pipe 42 which are communicated, the cross-sectional area of the reducing pipe 41 is larger than that of the non-reducing pipe 42, and then the reducing pipe 41 can form an internal storage space, and the space is larger, the reducing pipe 41 can buffer hot water in the heating element 1, specifically, when a user temporarily stops using water, the heating element 1 is closed, at this time, water is left in the reducing pipe 41, the temperature of the water is equivalent to the temperature set by the user, and the temperature in the reducing pipe 41 gradually decreases. Simultaneously reducer 41 can also mix the water of heating component 1 waste heat heating, specifically, when heating component 1 closed, the inside remaining water of heating component 1 (its temperature is user set temperature) can be heated by the waste heat once more, and then lead to the temperature to be higher than user set temperature, when the user used once more this moment, the water that is heated by the waste heat in heating component 1 can flow into reducer 41 earlier, and mix with the water of temperature decline in reducer 41, so that the high temperature water temperature reduces, flow out through delivery port 3 this moment, can not scald the user yet, and can not have the waste of water resource. And can also prevent that the temperature rise of instantaneous water heater waste heat is too high, leads to unfavorable conditions such as heating element 1 ageing to appear.

In this embodiment, one end of the reducer pipe 41 is connected to the heating assembly 1, and the other end is connected to the non-reducer pipe 42, so that the water in the heating assembly 1 flows into the non-reducer pipe 42 after passing through the reducer pipe 41, and then flows to a valve (such as a faucet or a shower head) used by a user. Preferably, the axis of the reducer pipe 41 is coincident with the axis of the non-reducer pipe 42, and the diameter of the reducer pipe 41 is larger than that of the non-reducer pipe 42.

As a preferable embodiment, the diameter of the reducer pipe 41 of the present embodiment is more than 5 times the diameter of the heating pipe of the heating assembly 1, and the length of the reducer pipe 41 is more than 5 times the diameter of the reducer pipe 41. Through the setting of this structure, can ensure that reducing pipe 41 has sufficient storage space to make the water of its interior cooling mix the back with the water after heating of heating element 1 waste heat, the temperature can reduce to not scalding the user. It will be appreciated that the diameter of the reducer 41 may be selected according to the model of the tankless water heater.

As shown in fig. 2, the reducer pipe 41 is communicated with the heating assembly 1 through a quick connector, specifically, a quick connector hole 411 is formed at one end of the reducer pipe 41, which is communicated with the heating assembly 1, and the quick connector can be connected to the quick connector hole 411 after being connected to one end of the reducer pipe 41.

In this embodiment, the reducer pipe 41 and the heating assembly 1 are hermetically connected by a sealing ring to prevent water leakage. The reducer pipe 41 and the non-reducer pipe 42 may be integrally formed or may be hermetically connected in other manners.

The instant heating type water heater of this embodiment, it is greater than the cross sectional area of non-reducing pipe 42 through reducing pipe 41 cross sectional area, namely can form storage space through reducing pipe 41, after heating assembly 1 stops heating, all store water in heating assembly 1 and the reducing pipe 41, wherein the water in the heating assembly 1 can be heated by the waste heat and heaied up, the water in the reducing pipe 41 can cool down gradually, when starting heating assembly 1 again, the temperature of the water of being heated by heating assembly 1 waste heat is higher than the temperature that the user set for, the high temperature water in the heating assembly 1 can flow into reducing pipe 41 and mix with the water after cooling in the reducing pipe 41 this moment, so that the high temperature water temperature reduces, later flow out through delivery port 3. At the moment, the water flowing out of the water outlet 3 can not scald the user and the waste of water resources can not exist.

Example two

The present embodiment provides an instantaneous water heater, which is different from the first embodiment in that the location of the reducer pipe 41 is different. Specifically, referring to fig. 3 and 4, two ends of the non-reducing pipe 42 of the present embodiment are respectively communicated with the heating assembly 1 and the water outlet 3, the reducing pipe 41 is disposed at one side of the non-reducing pipe 42, and water in the heating assembly 1 flows through one portion of the non-reducing pipe 42, the reducing pipe 41 and another portion of the non-reducing pipe 42 in sequence and then flows out through the water outlet 3. That is, at the position where the non-reducing pipe 42 is connected to the reducing pipe 41, it is in a closed state so that the water flow assumes the above-described flowing state.

As shown in fig. 4, the reducer 41 includes a body 412 and a baffle 413, the baffle 413 is inserted into the non-reducer 42 in a sealing manner and divides the non-reducer 42 into two parts which are not communicated with each other, an inlet and an outlet are formed between the baffle 413 and the body 412, and a cavity communicating the inlet and the outlet is formed inside the body 412, so that the reducer 41 forms two channels which are communicated with each other. The two channels form a U-shaped structure with the inlet communicating with the non-reducer pipe 42 and the outlet communicating with the non-reducer pipe 42 and the part of the heating assembly 1. Preferably, the reducer pipe 41 is arranged perpendicular to the non-reducer pipe 42.

When the instant water heater of this embodiment is used, when the user pauses the water use, heating element 1 closes temporarily, and the reducing pipe 41 internal storage of this moment leaves water, and the temperature of this water is equivalent with the user's settlement temperature, and the temperature descends gradually in reducing pipe 41, can remain the water by waste heat heating in the heating element 1. When the user uses water again, the water heated by the waste heat in the heating assembly 1 flows into the reducer pipe 41 firstly and is mixed with the water with the temperature reduced in the reducer pipe 41, so that the temperature of the high-temperature water is reduced, and the high-temperature water finally flows out for the user to use, and at the moment, the user can be prevented from being scalded.

The rest of the structure of this embodiment is the same as that of the first embodiment, and is not described again.

It should be understood that the above-described embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Numerous obvious variations, adaptations and substitutions will occur to those skilled in the art without departing from the scope of the utility model. And are neither required nor exhaustive of all embodiments.
