Technical field
The present invention relates to a kind of storage-type electric water heater, belong to the improvement technology of storage-type electric water heater.
Background technology
The storage-type electric water heater of prior art; In the inner bag bottom outlet pipe and water inlet pipe are housed; Mixed water valve is housed between outlet pipe and the water inlet pipe, and the delivery port of outlet pipe is communicated with the hot water inlet of mixed water valve, and the water inlet of water inlet pipe is communicated with the cooling water inlet of mixed water valve; Device has normally open solenoid valve between the water inlet of water inlet pipe and the cooling water inlet of mixed water valve; After water heater heating is accomplished, when the user uses, the hot water that gets into cold water and outlet pipe before the water inlet pipe through mix water valve mix obtain need use hot water.But there is following defective in the water heater of said structure: since the lower and cold water of inflow temperature from water inlet pipe get into behind the inner bag with inner bag in hot water mix; When making leaving water temperature not reach instructions for use; Mixing warm water in the inner bag can be high more a lot of than inflow temperature; Cause rate of thermal water utilization low, satisfied not the requirement of water consumption and waste energy.
Summary of the invention
The objective of the invention is to consider the problems referred to above and provide a kind of reasonable in design, added hot water in simple in structure, the inner bag and can fully use the storage-type electric water heater that rate of thermal water utilization is high.
Technical scheme of the present invention is: a kind of storage-type electric water heater; Comprise shell, heater, inner bag, temperature sensor, circuit board, first outlet pipe, water inlet pipe and mixed water valve; Wherein liner device in the enclosure, circuit board arrangement is on the inwall of shell, heater and temperature sensor place inner bag and are packed on the sidewall of inner bag; The water inlet pipe and first outlet pipe pass the bottom of canning at inner bag respectively; The delivery port of water inlet pipe is near the bottom of inner bag, and the water inlet of first outlet pipe then extends to the top of inner bag, and the delivery port of first outlet pipe is communicated with the hot water inlet of mixed water valve through water flow sensing unit; The water inlet of water inlet pipe is communicated with the cooling water inlet of mixed water valve through normally open solenoid valve; The bottom returning apparatus that it is characterized in that inner bag has second outlet pipe, and the water inlet of second outlet pipe is positioned at the middle part of inner bag, and delivery port passes shell and passes through the bypass pipe connection of the normally closed solenoid valve and second threeway; Second three-way device is on the pipeline between the cooling water inlet of normally open solenoid valve and mixed water valve, and normally closed solenoid valve, normally open solenoid valve, water flow sensing unit and automatic water-mixing valve are connected to circuit board through lead.
First threeway is housed on the said water inlet pipe, and normally open solenoid valve is communicated with the first threeway bypass pipe.
Said mixed water valve is that automatic or manual mixes water valve.
The length of said second outlet pipe is 1/3～2/3 of the first outlet pipe length.
Said normal temperature sensor places the medium position of inner bag.
The present invention has at utmost utilized to have added hot water in the inner bag owing to adopt two outlet pipe structures, has improved hot water effluent's amount, solves the low problem of storage-type electric water heater rate of thermal water utilization, has practiced thrift the energy.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail.
As shown in Figure 1; Storage-type electric water heater of the present invention; Comprise shell 1, heater 2, inner bag 3, temperature sensor 4, heat-insulation layer 5, circuit board 6, first outlet pipe 8, water inlet pipe 9, second outlet pipe 10 and mixed water valve 15; Wherein inner bag 3 devices are in shell 1, and circuit board 6 devices are on a side inwall of shell 1, and heat-insulation layer 5 is filled between inner bag 3 and the shell 1; Heater 2 and temperature sensor 4 place in the inner bag and are packed in by on the circuit board 6 one side inner bag evagination circular arc wall; Water inlet pipe 9, first outlet pipe 8 and second outlet pipe 10 pass shell 1 device respectively in the bottom of inner bag 3, and the delivery port 91 of water inlet pipe 9 is near the bottom of inner bag 3,81 tops that extend to inner bag 1 of the water inlet of first outlet pipe 8; The delivery port of first outlet pipe 8 is communicated with the hot water inlet of mixed water valve 15; Between the delivery port of first outlet pipe 8 and mixed water valve 15 hot water inlets on the pipeline device water flow sensing unit 16 is arranged, the water inlet of water inlet pipe 9 is communicated with the cooling water inlet of mixed water valve 15, device has normally open solenoid valve 13 between the cooling water inlet of the water inlet of water inlet pipe 9 and mixed water valve 15; The water inlet of second outlet pipe 10 is in the middle part of inner bag; Delivery port passes shell 1 and is communicated with the bypass pipe of second threeway 14 through normally closed solenoid valve 11, and second threeway, 14 devices are on the pipeline between the cooling water inlet of normally open solenoid valve 13 and mixed water valve 15, and normally closed solenoid valve 11, normally open solenoid valve 13, water flow sensing unit 16 and automatic water-mixing valve 15 are connected to circuit board 6 through lead.
In the present embodiment, first threeway 12 is housed on the said water inlet pipe 9, normally open solenoid valve 13 is communicated with first threeway, 12 bypass pipes.Said mixed water valve 15 mixes water valve for automatic or manual.
The length of said second outlet pipe 10 is 1/3～2/3 of first outlet pipe, 8 length.Said normal temperature sensor 4 places the medium position of inner bag.
During water heater working of the present invention, the inner bag middle part temperature value that the duty of said normally open solenoid valve 13 and normally closed solenoid valve 11 is recorded by temperature sensor 4 and the water-flow signal that records of water flow sensing unit 16 are confirmed.Be lower than the leaving water temperature that mixes water valve 15 or be lower than a certain temperature value when temperature sensor 4 records inner bag middle part temperature; And water flow sensing unit 16 is when recording first outlet pipe current being arranged; Normally open solenoid valve 13 is worked with normally closed solenoid valve 11 simultaneously, mixes water valve 15 this moment through first outlet pipe 8 and 10 water intakings of second outlet pipe.The warm water at the hot water that do not need high-temperature too and inner bag middle part is mixed to obtain to use the hot water that needs, make that to use up behind the hot water water temperature in the inner bag lower.At utmost utilize the hot water of inner bag heating, improved water yield, solved the low problem of storage-type electric water heater rate of thermal water utilization, energy savings.
