Abstract

The utility model relates to a feed water pipeline of a drinking water machine heating container, which is a water inlet pipe, one end of which is communicated with a cold water barrel, and the other end is connected with a water inlet of a heating container. The feed water pipeline is characterized in that the front end of the joint of the water inlet pipe and the water inlet of the heating container form a lower cambered structure which also comprises similar shapes like a U-shaped structure which has the same effect as the lower cambered structure. The distance from the lowest point of the feed-water pipe of the lower cambered structure to the bottom of the heating container is usually from 5 cm to 8 cm, and the best distance is from 7 cm to 8 cm. The feed-water pipeline is an improved low level feed-water pipeline which can effectively prevent convection heat exchange from happening and avoids that hot water in the heating container generate heat interchange with the water in the cold water storage barrel in the way of convection. The water at lower cambered structure actually plays a role of a heat insulation valve, and plays a key role for the heat loss reduction, partially solves the problems of overflow, and enables the quality of the water to be healthier.

Description

The inlet pipeline of water dispenser heating courage

Technical field

The utility model relates to the internal structure of water dispenser, particularly the inlet pipeline of water dispenser heating courage.

Background technology

Daily water dispenser, even water receiving in the water dispenser not, water dispenser is just heating once (the structure difference of water dispenser, the time on can difference) automatically every about 30 minutes always also.Usually, the heating-up temperature of water machine acquiescence is generally 80 ℃ (machine that has is about 60 ℃), the boiling water in the Heating Cup in other words, and in these 30 minutes, water temperature is from being reduced to about 80 ℃ near boiling.So not only caused waste of electric energy, and water is in always and constantly is heated state in the hot water liner, has formed thousand boiling water, ten thousand boiling water of our daily theorys, directly has influence on people's drinking-water health.

The reason of the quick reduction of water temperature must be because the quick loss of heat.The hot water liner of water dispenser all has usually and is incubated measure preferably, so radiation is relative less with the conduction dispersed heat.Can conclude that thus the convective heat exchange of cold water and hot water is only the main cause that heat runs off fast.Through being analyzed, the water dispenser structure draws as drawing a conclusion:

Cold water in the heating courage in hot water and the cold water water butt carries out the quick decline that convective heat exchange has caused water temperature.Cold water bucket is that straight line is connected with the tube connector that heats between the courage at present, heat exchange detail analysis following (in conjunction with the accompanying drawings 2): after the water in the heating courage is boiled, the coolant-temperature gage of a-quadrant, bottom is near 100 ℃, density is less relatively, and the water in water inlet pipe B zone is cold water, and density is bigger, like this, because the flowability of water, the water of a-quadrant water just continuous and the B zone carries out thermal convection current, the water temperature of ordering near A up to the coolant-temperature gage in B zone; In like manner, the water after heating up in B zone also by water inlet pipe constantly with the cold water thermal convection current of water butt, cause the also constantly rising of coolant-temperature gage of whole water butt.Pass through this heat exchanging process continuously, the heat in the heating courage constantly is passed in the water butt, because the water butt volume is big, is not incubated measure, has just caused the quick loss of heat.It is continuous that the result that heat runs off causes heating the interior water temperature of courage, reduces, and is reduced to default temperature once, and water dispenser is heating automatically just.This constantly automatic phenomenon that heats of water dispenser that we mention just occurred.Another result who brings thus is, constantly interior with the heating courage boiling water of water in the water butt mixes, and forms the mixing water on the practical significance in heating courage and water butt, that is to say, " cold water " in the water butt is mixing water, thousand boiling water too, grievous injury our health!

Present circuit design on the market, because cold water density is big, hot water density is little, the hot water of a-quadrant cold water easy and the B zone produces convective heat exchange, the water of process heat exchange in the B zone produces heat exchange with the D regional water again then, and this heat exchanging process can pass up to water butt always.The result of this heat exchange that does not stop finally causes the water in the Heating Cup constantly to be exchanged for cold water, causes heating rod in the heating that does not stop, and the waste electric energy burns till thousand boiling water again easily.Find that through observing under the normal temperature, if after the water in the cold water water butt is less than 2L, the water machine heated more than 4 hours, the water temperature in the whole cold water water butt could reach more than 40 degree!

Summary of the invention

Technical problem to be solved in the utility model provides a kind of inlet pipeline of improved water dispenser heating courage, effectively stops the generation of the cold water convective heat exchange in interior hot water of heating courage and the cold water bucket, reduces the consumption of electric energy.

The inlet pipeline of the utility model water dispenser heating courage is a water inlet pipe, and water inlet pipe one end is communicated with cold water bucket, and the other end connects heating courage water inlet, it is characterized in that described water inlet pipe and heating courage water inlet junction front position are the arc lower structure.

Described arc lower structure also comprises similar shape, and as U type structure, their effect is identical.The perigee distance heating courage bottom of water inlet pipe that is the arc lower structure is at least more than the 5cm, generally at 5～8cm, and best 7～8cm.

The utility model can effectively stop the generation of convective heat exchange through " low level inlet pipeline " after improving.Avoided the interior hot water of heating courage by the mode of convection current and the water generates heat exchange in the cold water water butt, in fact the water at arc lower structure place played the effect of a heat insulation valve.Played key effect for reducing thermal losses.

The material of water inlet pipe can be used general sebific duct now, and the minimum point after the assurance sebific duct is sagging is lower than heating the interior minimum point of courage, just can play the effect of good insulation.Different water dispenser models can be determined the length of sebific duct according to the inner space size.Also can directly adopt productions such as flexible plastic to become shape described in the utility model.

Advantage of the present utility model:

Can effectively stop the generation of the cold water convective heat exchange in hot water and the cold water bucket in the heating courage, reduce the consumption of electric energy, solution thousand boiling water that can part, the problem of ten thousand boiling water make water quality health more.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the prior art constructions schematic diagram.

Among the figure: 1 heating courage, 2 cold water buckets, 3 water inlet pipes, 4 curved pipes

The specific embodiment

As Fig. 1, the inlet pipeline of the utility model water dispenser heating courage is water inlet pipe 3, water inlet pipe 3 one ends are communicated with cold water bucket 2, the other end connects heating courage 1 water inlet, and water inlet pipe 3 is the arc lower structure with heating courage 1 water inlet junction front position, is one section curved pipe 4 form.The perigee distance heating courage bottom of curved pipe 4 is preferably 7～8cm generally at 5～8cm.

The minimum point C point that is the water inlet pipe (curved pipe 4) of arc lower structure will be lower than the bottom surface A point of heating courage, like this since, though the water in a-quadrant and B zone still can carry out heat exchange.But the C point is that cold water density is big, is difficult for carrying out convective heat exchange with the water in B zone again, has guaranteed to heat the cup of hot water no longer by the mode and the interior water generates heat exchange of cold water water butt of convection current, and in fact the water in C zone played the effect of a heat insulation valve.Played key effect for reducing thermal losses.
