Description

Beforehand instant double-mode electric water heater
Technical field
The utility model relates to the electric heater field.
Background technology
Existing electric heater is divided into two classes, one is storage-type, and two is Instant heating type, and storage-type electric water heater includes a storage tank, and in water tank, establish electrothermal tube, storage-type electric water heater has that electrothermal tube power is low, the water yield is sufficient and characteristics such as water temperature height, and volume is big, heat time heating time long, electrothermal tube is immersed in the water for a long time but also exist, and its surface generates incrustation scale easily, make shortcomings such as efficiency of heating surface reduction, in addition, contain in the water tank and do not use up hot water, the heat radiation of water tank causes energy waste.Instant electric water heater's heater then adopts the structure of installing in the volume smaller container than the large power, electrically hot body, current can heat through in the heater, characteristics with instant heating, volume is little, easy for installation, but exist power big, the defective that the water yield is little, when particularly winter, environment temperature was low, the not enough situation of hot water (unless high-power heater is installed) often appearred.
Application number is 02279083.7 patent " water storage instant electric water heater ", a kind of instant electric water heater who has water storage tank is proposed, this water heater principle is to store a certain amount of hot water in advance by water storage tank and heater, during water, heater has so just solved existing instant electric water heater's the not enough problem of hot water in winter to hot a little again the getting final product of water of water storage tank.There is following deficiency in this patent:
1. booster pump is located on the outlet pipe, also will start booster pump when not needing preheating water, wastes energy.
2. adopt triple valve to control circulation preheating, complex structure.
In addition, existing electric heater does not have heat sinking function, and in the water heater use or after using, built-in temperature is higher, electric elements damage easily.
Also have, existing electric heater does not have the warm braw function, and than cold district, people will warm up the room air heating with warm-air drier before using water heater usually.
The utility model content
The purpose of this utility model is to propose a kind of beforehand instant double-mode electric water heater, it has preheating and two kinds of patterns of instant heating, power is between 3000W to 6000W, it is too big both to have solved existing instant electric water heater's power, in the not enough problem of hot water in winter, solve too big, the problems such as heat time heating time is long, the surperficial easy generation incrustation scale of electrothermal tube of storage-type electric water heater volume again, have characteristics such as rational in infrastructure and easy to use.
Another purpose of the present utility model is to make water heater have heat sinking function.
Another purpose of the present utility model is to make electric heater have the warm braw function.
The following mode that the utility model can pass through realizes:
A kind of beforehand instant double-mode electric water heater, there are shell, circuit part and pipeline portions to constitute, wherein, pipeline portions includes water inlet pipe, outlet pipe, storage tank and heater, and heater is a tube heater, storage tank connects water inlet pipe and outlet pipe, it is characterized in that: storage tank separates with heater, and heater is serially connected with on the outlet pipe, and pipe connects a water circulating pump between water inlet pipe and the outlet pipe, make water circulating pump, heater and storage tank constitute the loop, water circulating pump and heater interlock.
Further design is to be provided with water flow switch on water inlet pipe or outlet pipe, water flow switch and heater interlock, and water flow switch can be hydraulic pressure switch, pressure sensor or flow sensor etc.
Described heater is the tube electric heater of external heater, and this external heater has 2 effects, the one, the heater inner fluid is heated, and the 2nd, by the air of convection type circumference.
As optimization, shell is provided with air inlet and air outlet, installs over against the air outlet position in the shell and is electrically connected a fan, and this fan is a radiator fan, is again the warm braw fan.
Storage tank can place in the shell, also can place outside the shell or with shell and connect and compose integrative-structure.
Relevant circuit part, available known technology is realized, is not described in detail at this.
During use water inlet pipe, outlet pipe are connected respectively to running water pipe and user's tap, the utility model can be used as common instant electric water heater and two kinds of schemes of beforehand instant double-mode electric water heater are used:
When using as common instant electric water heater, directly open user's tap behind the connection power supply and get final product, at this moment running water enters storage tank after outlet pipe flows out and heater via heating becoming hot water uses the water flow switch unlatching from water inlet pipe, the work of interlock heater, the recirculated water air pump inoperative.
When using as beforehand instant double-mode electric water heater, press the preheating button of being located in the circuit part after connecting power supply, at this moment, water circulating pump starts, with the circulation of the water storage in the storage tank, the work of interlock heater is along with the coolant-temperature gage in the storage tank is elevated to design temperature gradually, controller in the circuit part sends buzzing and indicator lamp prompting, and water circulating pump and heater quit work simultaneously.Can directly open user's tap subsequently, at this moment the preheating water in the water tank flows out through outlet pipe, and the use of heater via further heating becoming hot water, and water flow switch is opened, the work of interlock heater, and it is additional that running water enters storage tank from water inlet pipe.
For the structure that fan is installed, the utility model has following several situation:
When using water heater, fan starts simultaneously, makes air and outside air exchange in the machine, reduces the surface temperature of electric elements; Can also set the fan delay switching-off, use aft-fan also to be held open a period of time, the electric elements surface temperature is descended rapidly at water heater.
When not using or preparing to use water heater, can use the warm braw function separately, press " warm braw " button, fan and heater are opened simultaneously, the recirculated water air pump inoperative, and water flow switch is not opened, at this moment because the water in the heater is mobile, heter temperature raises rapidly, and flow air is heated through heater in the bathroom, realizes the warm braw function.
When using the beforehand instant double-mode electric water heater pattern, automatic/hand starts the warm braw function, and fan flows the air in the bathroom, flow air is heated through heater, like this, heater has also heated the air in the bathroom in heating storage tank water storage, make warm-air drier and use.
Be compared with the prior art, the utlity model has following characteristics:
1. rational in infrastructure, simple, easy to use.
2., can guarantee that also enough hot water uses even in the winter of cold.
3. electric heater separates with storage tank, and heater does not have incrustation scale to produce thermal efficiency height.
4. do not need the season of preheating water, do not start preheat function, stored hot water not in the storage tank, storage tank only uses as the running water passage, helps cleaning storage tank like this and has overcome the shortcoming that wastes energy because of savings hot water.
5. the structure that has fan has heat radiation and warm braw function, a tractor serves several purposes, and heat radiation not only can be used as warm braw, and heat radiation can also prolong the service life of heater and electric elements.
