Abstract
The present invention discloses an energy-saving heat regenerative shower bath composed of a hanging type outer housing, a heater, a heat exchanger, a self-suction shower bath waste water pump, a cool water pressure pump and the like. When said shower bath runs, the shower bath waste water is sucked by the waste water pump, pressed, and fed to the heat exchanger, and is then discharged out after transferring heat to the tap water; after being preheated, the tap water is fed to the heater where it is heated to the shower bath temperature, and is carried to the sprinkler head, or is directly mixed with hot water and flows to the sprinkler head. The present invention can adopt fuel gas, electric energy or solar energy to heat, can supply three times hot water as that of a water heater during a shower bath or exhibit two third energy-saving. The present invention is also suitable for situations of no tap water or low water pressure.
Description
The invention discloses a kind of can reuse shower after waste water residual heat improve shower running water inflow temperature, thereby reduce to heat the temperature difference, strengthen the hot water productive rate, energy savings, energy-saving heat regenerative shower bath safe in utilization.
The shower of family expenses is divided into storage water heater and quick-heating type two big classes now, and its thermal source is respectively fuel gas buring, electric energy, solar energy etc.Quick-heating type directly is heated to water about 40 ℃ from 15 ℃ and uses for the people; Storage water heater electricity consumption or sunshine are heated to water more than 40 ℃, add to convert an amount of cold water and water temperature is dropped to about 40 ℃ use for the people again.In fact, through the wastewater temperature after the human body shower also about 35 ℃.That is to say that the shower process has only been used about 20% energy, all the other major parts have all been wasted in vain.
Purpose of the present invention just provides and can overcome above-mentioned defective, and energy savings strengthens hot water flow, energy-saving heat regenerative shower bath safe in utilization again.
The objective of the invention is to realize as follows:
When shower, shower waste is collected into together drains after cold running water with the need heating maybe need add the cold running water generation heat exchange of converting again.Deliver in the heater again behind the cold running water absorption shower waste waste heat and heat, just can reduce to heat the temperature difference significantly, make limited heating power can burn more hot water, strengthen hot water productive rate, the purpose of energy savings thereby reach; Need add and obtain more shower warm water with the mixed available limited hot water of hot water again after the cold running water of converting absorbs the shower waste waste heat.Thereby reach energy-conservation purpose.
The present invention is described in further detail below with reference to accompanying drawing.
Fig. 1 is the normal cross-section schematic diagram of a kind of quick-heating type concrete structure of the present invention.
Fig. 2 converts cold water formula structure water route principle schematic of the present invention adding.
Fig. 3 is the screw-casing tubular type structural representation of heat exchanger.
Fig. 4 is heat exchanger shower waste and cold running water schematic flow sheet between the heat exchanger wallboard when being the multi-layer helical plank frame.
Fig. 5 be heat exchanger around the tubular structure schematic diagram.
With reference to Fig. 1, a wall hanging or movably in the hard shell [1] heat exchanger [2] heater [3] is housed, hydraulic pressure or water temperature control switch [4], self-priming cold running water force (forcing) pump [5], self-priming waste water force (forcing) pump [6] and take over power switch, line etc.Cold running water is by opening a side that enters heat exchanger [2] in the aperture [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 cold running 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 cold running water force (forcing) pump [5] of connecting of common motor.Self-priming cold running water force (forcing) pump [5] extracts cold running 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.The thermal source of heater [3] is an electric energy, and fuel gas buring can wait.
When heater adopts solar energy heating or heater to be placed on the bathroom, can adopt shown in Figure 2 adding to convert the cold water energy-saving scheme and deploy.Heater section and energy-conservation heat exchanging part are made absolute construction respectively, respectively place correct position, connect with pipeline.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 cold running water after flexible pipe enters sewer through the 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; Need add the cold running water of converting and absorb the shower waste liberated heat therein through the opposite side that water control valve door [9] enters heat exchanger [2], temperature improves that back and the hot water of heater output are mixed to be changed to about 40 ℃ temperature to be used for the people by the shower nozzle ejection again.
Heat exchanger [2] can be made into screw-casing tubular type structure shown in Figure 3, multi-layer helical plank frame shown in Figure 4 or shown in Figure 5 around tubular structure.When adopting Fig. 3 structure, outer tube [10] is used flexible metal tube, waved plastic pipe or flexible plastic pipe, rubber tube.Interior pipe [11] is single or many metal tubes.
When adopting structure shown in Figure 5, interior pipe [11] is single or many metal tubes in parallel, outer effective metal or plastics.As shown in Figure 5, as adopting electrical heating, heater [3] can directly place heat exchanger [2], flows to shower nozzle after the running water after the waste water preheating directly enters the inner chamber heating.
A is that cold running 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 and cold running water become counter-flow arrangement and can be with fin or disturbing flow device to improve the heat exchange effect in heat exchanger.Consider that shower waste has impurity, preferably it is deployed a side more free from worry in heat exchanger [2].Hydraulic pressure or water temperature control switch are avoided heater generation dry combustion method phenomenon.
