Abstract
The utility model discloses a heat back type quick heating electric shower device which is composed of a wall hanging type or a ground moving type hard casing and a heater, a heat exchanger, fresh water, a pressure pump for shower wastewater, etc., which are arranged in the casing. When the utility model is used, shower wastewater is sucked by the self-suction type wastewater pressure pump. After pressurized, the shower wastewater is introduced into the heat exchanger. After the shower wastewater releases heat to the running water, the shower wastewater is exhausted. After preheated, the running water is introduced into the heater. When heated to the shower temperature, the running water is discharged. Compared with a common water heater, the utility model can save more than a half of energy, the utility model has a self-suction type pump simultaneously, and is suitable for situations without running water or with low water pressure.
Description
The utility model discloses a kind of can reuse shower after waste water residual heat improve shower running water inflow temperature, thereby reduce the heating temperature difference, strengthen the hot water productive rate, the conservation of power energy, backheating type quick electrothermal shower safe in utilization.
The electric heating shower of family expenses is divided into storage water heater and quick-heating type two big classes now.Because the residential electric power load is generally about 2 kilowatts, so that running water is heated to 40 ℃ of calculating from 15 ℃, all power are used for heating shower water, then make its hot water productive rate of electricity consumption quick-heating type shower also can only reach level about 1 liter/second, and such water yield uses just too little.When adopting the water storing type shower, though overcome the too little deficiency of power, 40 liters of shower waters of preheating also need heat about 40 minutes, and the stand-by period is oversize, and are if need many people to use continuously, then more inconvenient.
The purpose of this utility model just provides one and can overcome above-mentioned defective, and energy savings strengthens hot water flow, backheating type quick electrothermal shower safe in utilization again.
The purpose of this utility model realizes as follows.During shower, generally be running water to be heated to about 40 ℃ from 15 ℃ use.In fact, the temperature of bathing back waste water is also at 30 ℃-35 ℃, and in other words, the shower process has only been used about 1/4th of whole heat energy, and remainder has all been drained by sewer.If when shower, shower waste is drained after being collected into together fresh tap water generation heat exchange with the need heating again, deliver in the heater again behind the fresh tap water absorption shower waste waste heat and heat, just can reduce to heat the temperature difference significantly, make limited power can burn more water, strengthen the hot water productive rate thereby reach, the purpose of energy savings is described in further detail the utility model below with reference to accompanying drawing.
Fig. 1 is the normal cross-section schematic diagram of a kind of concrete structure of the present utility model.
Fig. 2 is a water route of the present utility model circuit theory schematic diagram.
Fig. 3 is the screw-casing tubular type structural representation of heat exchanger.
Fig. 4 is heat exchanger shower waste and fresh tap water schematic flow sheet between the heat exchanger wallboard when being the multi-layer helical plank frame.
With reference to Fig. 1 Fig. 2, but in wall-hanging or the hard shell [1] that moves on ground heat exchanger [2] is housed, heater [3], hydraulic pressure or water temperature control switch [4], self-priming fresh water force (forcing) pump [5], self-priming waste water force (forcing) pump [6] and take over power switch, line etc.Fresh tap water is by opening a side that enters heat exchanger [2] in the hole [12] of hard shell [1] sidewall or bottom through water control valve door [9], absorbed therein and enter heater [3] again behind the shower waste liberated heat and further be heated to the shower temperature, led to shower nozzle through taking over by hard shell [1] sidewall or bottom port [7] then.During shower, through falling behind the human body in bathtub or periphery is shaped on the soft pad [8] that catchments of the flange that is filled with water, the self-priming waste water force (forcing) pump [6] in the hard shell [1] is passed to fresh tap water after flexible pipe enters sewer through the opposite side that an end places the bathtub bottom or the flexible pipe that links to each other with the soft pad [8] that catchments is sent into heat exchanger [2] after the shower waste suction is wherein pressurizeed with waste heat by the hot water of shower nozzle ejection.On the low side or do not have under the situation of running water at tap water hydraulic, with self-priming waste water force (forcing) pump [6] but the coaxial self-priming fresh water force (forcing) pump [5] of connecting of common motor.Self-priming fresh water force (forcing) pump [5] extracts fresh water from running water pipe or other water source, and heat exchanger [2] is sent in its pressurization, and heater [3] carries out preheating, is sent to shower nozzle after the heating again.
Heat exchanger [2] can be made into screw-casing tubular type structure shown in Figure 3 or multi-layer helical plank frame shown in Figure 4.When adopting Fig. 3 structure, outer tube [10] is with waved plastic pipe or flexible plastic pipe, rubber tube.Interior pipe [11] is single or many metal tubes.
A is that fresh tap water flows among Fig. 4, and B represents that shower waste flows to, letter back sequence number size expression water (flow) direction.
In order to improve the heat exchange effect, shower waste becomes counter-flow arrangement with fresh tap water in heat exchanger.Attractive in appearance for the waste water pipeline is arranged, the waste water drain hose of the suction hose of self-priming waste water force (forcing) pump [6] and heat exchanger [2] can close makes sleeve type structure.
Can singly adorn in the heater [3] or the several heating tubes of installing in parallel to regulate heating power, hydraulic pressure or water temperature control switch are avoided heater generation dry combustion method phenomenon.
