Abstract
The utility model relates to a preheating, instant heating mixed type electric water heater, which comprises a shell, an electrical control device, and a preheating type electric water heater which is installed in the shell. An instant heating type electric water heater which is connected in series with the preheating type electric water heater is also installed in the shell. The utility model keeps a lower preheating temperature to a preheating water tank to lead the heat loss of the preheating water tank to be low. The defect that the preheating type electric water heater has high heat loss is overcome. Preheated water can be quickly heated to a desired showering temperature without too large power, when the preheated water passes through the instant heating type electric water heater. Consequently, the defect that the instant heating type electric water heater has large power is overcome.
Description
The utility model relates to the electric heater that a kind of family and unit use, and particularly a kind of preheating is the hot mixed type electric heater.
In the prior art, two kinds of electric heaters are arranged; A kind of is the preheating type electric heater, and another kind is the instant electric water heater.Preheating type electric heater water temperature holding temperature is higher than more than 40 degree, and thermal losses is big; Heat time heating time is long, can't use hot water continuously; The instant electric water heater then heats soon, can use hot water continuously, and then power is too big but will satisfy the shower requirement, is difficult to use in most of family.
It is the hot mixed type electric heater that the purpose of this utility model is to provide a kind of preheating, can be double get the advantage of preheating type and immediate heating type electric heater and avoids their shortcoming, can use hot water under not too big power continuously, is suitable for the use of most of family.
For achieving the above object, the utility model adopts following technical proposals: the utility model is the same with prior art to be included housing, an electrical control gear and is installed in the interior preheating type electric heater of housing.It is characterized in that also installing in the housing immediate heating type electric heater of connecting with the preheating type electric heater.Before use, open the preheating type electric heater earlier the water among the preheating water tank is carried out preheating, make the water temperature among the preheating water tank remain on 25 ℃ of lower left and right sides temperature, during shower, open the immediate heating type electric heater, the preheating water that the preheating water tank is supplied with heats rapidly provides shower water, and it is temperature required then only to need less power can realize being heated to rapidly shower.
The utility model compared with prior art, have following conspicuous advantage: the preheating type electric heater in the utility model heats the preheating water tank, keep lower preheat temperature, make its thermal losses less, thereby the defective that the thermal losses that overcomes the preheating type electric heater is big, again through the heating of immediate heating type electric heater, then need not too big power, preheating water can be heated to shower rapidly temperature required through the water of preheating, realize small-power heating rapidly continuously, use for continuous shower.Like this, just can in most of family, use.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the circuit theory diagrams of the electrical control gear of Fig. 1 example.
Optimum implementation of the utility model is: referring to Fig. 1, this preheating is that the hot mixed type electric heater includes housing 2, an electrical control gear and is installed in preheating type electric heater 3 in the housing 2, and an immediate heating type electric heater 5 of connecting with preheating type electric heater 3 also is installed in the housing 2.Preheating type electric heater 3 is by a preheating water tank 4 inner chamber bottoms electric preheating element 8 to be installed to constitute; Immediate heating type electric heater 5 is to be made of the closed immediate heating type electric hot water element 7 of connecting; The outlet 12 of preheating type electric heater 5 is communicated with the import 6 of immediate heating type electric heater 5, and the outlet of immediate heating type electric heater 5 connects outlet pipe.Preheating water tank 4 import 15 is connected water inlet 14 by a magnetic valve 13, and preheating water tank 4 import 15 has a siphunculus 17 to be connected to preheating water tank 4 inner chamber tops; A floating drum 18 is installed on preheating water tank 4 inner chamber tops, and the connecting rod of floating drum 18 is connected with the water level switch 1 that is installed in preheating water tank 4 tops; The preheating water tank is equipped with water cut-off protection switch 16 in 4 bottoms; On the pipeline 11 of connection immediate heating type electric heater 5 imports 6 flow switch 10 is housed.Referring to Fig. 2, this preheating is that the electrical control gear of hot mixed type electric heater is by being that hot water radiation wire W1, pre-hot water radiation wire W2, two relay J 1, J2, flow switch K1, water inlet button switch K 2, water cut-off protection K switch 3, temperature detect switch (TDS) K4, water level switch K5, magnetic valve DV and indicator lamp D constitute.The circuit structure of electrical control gear is: by 220 volts of ac power supplies, pre-hot water radiation wire W2 be connected two poles after the contact J1-1 of relay J 1 connects; Be the zero line that hot water radiation wire W1 one end connects power supply, and a contact a of other end connection traffic K switch 1 and connect the live wire of power supply convertiblely; Another contact b of flow switch K1 connects three circuits parallel with one another: circuit is a water cut-off protection K switch 3 and be connected in series temperature detect switch (TDS) K4 again after a relay coil J1 connects, and indicator lamp D is in parallel with temperature detect switch (TDS) K4; Another circuit is into water button switch K 2, relay coil J2 and water level switch K5 series connection, and a circuit is that relay contact J2-1 connects with magnetic valve DV again; The other end of this three-line connects the zero line of power supply.Before the shower, flow switch K closes, be in the b contact and connect the live wire state, press the into button of water button switch K 2, then magnetic valve DV opens, to preheating water tank's water inlet, during cistern water level no show predetermined water level, water level switch K5 closes, then relay coil J2 energising, relay contact J2-1 closes energising, and then when water inlet button switch K 2 was rebounded unlatching, magnetic valve was still powered, when cistern water level arrives predetermined water level, water level switch K5 opens outage, relay coil J2 dead electricity and contact J2-1 opens then, magnetic valve DV outage and closing.Certain water level is arranged in the water tank, the then closed energising of water cut-off protection K switch 3, water temperature is lower than when setting 25 ℃ of preheat temperatures in the water tank; the closed energising of temperature detect switch (TDS) K4, then relay coil J1 energising, the closed energising of contact J1-1; then pre-hot water radiation wire W2 energising is carried out preheating to the water among the preheating water tank.When the preheating water temperature reached 25 ℃, relay coil J1 dead electricity was touched pass J1-1 and is opened, and pre-hot water radiation wire W2 dead electricity stops preheating.The water tank middle water level is lower than when setting low water level, and the water conservation K switch 3 that continues is opened, relay coil J1 dead electricity, then pre-hot water radiation wire W2 dead electricity and not heating.During shower, open electric heater outlet pipe switch, then flow switch K1 contact a connects, and contact b outage then is hot water radiation wire W1 energising, and the immediate heating type electric heater is in running order.
