Water heater equipment
Technical field
The present invention relates to a kind of water heater equipment, its hot water that is used to provide practical is discharged, and described water heater equipment comprises pneumatic water heater or combined type recirculation heater and water heater member, and it has cold water and enters and the warm water discharge pipe.
Background technology
At home and in place, use gas heater usually with less hot water demand.In described gas heater, can find circulator type by the current operation of drawing by the hot water tap who opens the dry point place.The water that comprises in the tube portion of heating between water heater and dry point, and the slower heat transfer startup that is used for heating when current begin all causes following problem: even spent the relatively long time, also have only cold water or the inabundant water that heats to arrive dry point.This shortcoming is horrible, especially under situation than small amount of thermal water is obtained in hope, and the amount that time and water all had very big waste and in fact do not utilize this moment.Device just begins when flow usually with the work of maximum gas burner power, yet, this may cause the heating of crossing after the initial period of being mentioned, and this also may be horrible, for example do not expect under the situation of water of heating, during the unlatching next time that repeats within a short period of time the user.
In addition, also use pneumatic type to store the heater boiler, it comprises built-in buffer container.Hot water from then on buffer container is transferred to water intaking place.Described container heats in a controlled manner, and this produces gas burner power consumption characteristics more smoothly.If buffer container is big or small less, this buffer container can significantly not increase device size so, but hot water will run low very much.If buffer container is bigger, use up so more tardy life, if but do not take hot water in the long period, it is unnecessary that the combustion gas energy that is used to heat so can show as.Can reduce this shortcoming by increasing thermal insulation, can cause cost to increase but increase thermal insulation.
Also might use to be placed on the outer buffer container of device, device size can not increase whereby, but must use independent circulating pump just can reach controlled temperature, and cost is also higher like this.
These solutions have a common shortcoming, are not promptly having not provide any hot water under the situation of gas supply, or have only bigger buffer container just to be fit to more effective interim hot water supply.
The water heater of another frequent species uses electrical heating, and described water heater with the standby hot water storage of controlled temperature in the apparatus container of thermal insulation.The advantage of described water heater is simply and cheaply to realize thermoregulator possibility.Yet the shortcoming of described water heater is that it needs more space than circulation gas combustion apparatus usually, and consumes considerable electric power.Another shortcoming of described water heater is under the situation of the outage of long period, does not have the hot water supply.
Summary of the invention
Target of the present invention is to find a solution, even it is frequently being taken hot water or is only taking under the situation of a small amount of hot water and also eliminated late effect, and simultaneously it has favourable energy consumption, even need less initial outlay and also can operate under the situation that does not have considerable energy supply.
The present invention is based on the advantage of its pneumatic type water heater capable of being combined and the understanding of the advantage of the electric heater with small size container, and uses this equipment, can realize optimum operation and in fact unconverted general arrangement size.
Another advantage of this equipment is to eliminate the effect that takes place when getting very small amount of hot water, this moment is less because of measuring, gas heater can not start automatically, and even only cold water flow into to store in the heater container, store the heater container and after many times taking on a small quantity, only store cold water.Yet in the solution that we provided, electricity stores heater hot water storage tank and consistently water is heated, and till reaching preset temperature, this is that interval between short intervals carries out.Therefore, described solution provides minimizing of heat balance and container size.
Target of the present invention is to be realized by the water heater according to introductory paragraph, wherein storage type electric heater is in series inserted in hot water discharge pipe's line, and described electric heater is equipped with thermostat.

The specific embodiment
In Fig. 1, show optional pneumatic type circulating hot water apparatus 1.Pneumatic type hot water apparatus 1 has cold water and enters pipeline 2 and hot water discharge pipe's line 3.In series devices, the electric heater 4 according to the present invention that externally is connected to first forward part is inserted in hot water discharge pipe's line 3.Electric heater 4 has: electric connector 8, and it is connected to heating wire; And thermostat 5, it detects the temperature of stored air blowing water, and correspondingly controls heating wire.According to Fig. 1, it is outside but very near in hot water discharge pipe's line 3 of pneumatic type circulating hot water apparatus 1 that electric heater 4 is inserted in pneumatic type circulating hot water apparatus 1.From effectively utilizing the viewpoint in space, this equipment can be favourable.In the case, the container that covers electric heater 4 with heat-insulating material can be useful, because because it is placed on the outside, so it does not contact with a large amount of available additional heat.Electric heater 4 can be placed to towards dry point in hot water piping further from pneumatic type circulating hot water apparatus 1.
Under the situation of another embodiment shown in Fig. 2, electric heater is built in the pneumatic type circulating hot water apparatus 1.Its advantage is to guide or to dismantle hot water piping.Its another advantage can be under the situation of appropriate design and placement, and the buffer storage container of electric heater 4 can utilize the script used heat useless of emitting in the pneumatic type circulating hot water apparatus.For this reason, can use the heat transfer element in the combustion space 7 that penetrates pneumatic type circulating hot water apparatus 1, and by heat transfer, the water yield that is comprised in the heat transfer element preheating electric heater 4, thus the amount that is heated to the default necessary electric energy of minimum temperature reduced.Carry out this heating in a controlled manner, promptly thermostat 5 keeps being included in the water of (promptly in buffer container) in the electric heater 4.
For selecting low storage capacity just enough, because it is used for the temperature delay and the excessive movement of single water heater of complemental air dynamic formula or combined type circulating hot water apparatus 1 basically as the electric heater 4 of buffer container work.For this reason, application is generally just enough less than the buffer container of 20 liters (for example 5 to 15 liters).Yet, can pass through the completely stable temperature of thermostat 5 adjustment of electric heater 4 in the acquisition of dry point place for described buffer volumes.The cycle of electric heater 4 beyond water intaking be heating system also, so the small size container is just enough.This temperature can be chosen as relatively lowly, this can not stop after postponing sometime yet, will arrive dry point by the water pneumatic type hot water apparatus 1 supply much possible hot yet.When the tap at dry point place is closed, remaining water will have the high temperature of presetting than thermostat 5 of temperature in the container of electric heater 4.Then, before the water that is comprised cools off once more, do not need the electrical heating operation in buffer container.Whereby, can realize favourable energy consumption, eco-friendly operation.
By equipment according to the present invention, can propose under the situation that does not have combustion gas or very big electric current, there is the possibility of taking practical hot water.Simultaneously, also eliminated the unfavorable delay of pneumatic type water heating with more favourable economy, because the water balance that is comprised in the electrically heated buffer container thermotonus slowly, or cross heating under the situation of single water heater or combined type circulating hot water apparatus.Having less relatively electrically heated buffer container only increases size in not half ground, and consumes electric energy seldom.With the integrated situation of pneumatic type device under, buffer container does not need a large amount of thermal insulation.
