Description
Technical field
The invention discloses a kind of hot water for shower production and system noise and coolant controlled new method and device that shower waste is thermal source of take, belong to Engineering Thermophysics and bathroom technical field.
Background technology
Existing take shower waste be thermal source produce the method for hot water for shower and device thereof the earliest by Dang Kunxuan, Lu Yingmei invention and in July, 1996 26Xiang Patent Office of the People's Republic of China submitted application for a patent for invention to, this application authorized (title: a kind of method of producing hot water for shower bath and device thereof, patent of invention number: however ZL96118737.9). there is the deficiency of following aspects in this patented method and device thereof in actual use:
The firstth, running noise is too large: the compressor of modern industry level manufacture and waste water pump are contained in and in metal case body, be suspended near the human body isometry position on toilet wall, when compressor and waste water pump operation, whole casing can produce continuous vibration and very large resonance noise, and its situation is similar to the outer machine duty that detachable air conditioner hangs on open air.And this noise exactly just does not stop grumbling in a grand fashion in one's ear of user during shower, this allows people's endurable.
The secondth, shower water temperature is unstable: aforesaid, in early invention, in order to collect shower waste, must stand on the limited cushion of size during people's shower.Thereby but people's limb action can cause part waste water to splash, shed and make the wastewater flow rate temporal evolution collected beyond cushion, this causes the temperature of hot water for shower of device output, and also the changeable people of allowing fluctuated is at a loss as to what to do thereupon.
The 3rd is the difficult normal use of winter, two seasons of summer: winter, when running water temperature is lower than 7 ℃ or following (northern China and the Yangtze river basin are used the area of surface water all to have this type of situation to occur except south China) Time, only with the part effluent segregation of above-mentioned patent, without the control method of heat exchanger, be certain to occur the too low situation that causes waste water to freeze obstruction and cannot use of evaporating temperature; Summer, when temperature during higher than 33 ℃ earth's surface running water temperature conventionally also higher than 25 ℃, at this moment there will be again because the too high hot water for shower that causes device output of device condensation temperature scalds people, now only depend on effluent segregation method to regulate and also cannot prove effective.That is to say, employing is difficult in winter, two seasons of summer the hot water for shower that production can normally be used at the machine of patent control method morning.
The 4th, inhale, in drainpipe cannot be ensconced wall (because this system has into and out of, suction, four water pipes of draining), affect the neat appearance of toilet.
Summary of the invention
The present invention realizes continuous production hot water for shower for the object of the continuous shower of people to extract heat from least recently used shower waste, the invention discloses a kind of hot water for shower production and system noise and coolant controlled new method and device that shower waste is thermal source of take.Technical scheme of the present invention can overcome the above-mentioned deficiency in patent morning, significantly reduce noise in the system running noise that especially people's ear can be heard during shower, keep shower process hot water temperature's substantially constant and all can normally use throughout the year, can also keep to greatest extent the neat appearance of toilet simultaneously.
The technical scheme of control of the present invention and noise decrease is the base member that the system components such as compressor and water pump are installed above, places oneself in the midst of these five faces of front, back, left, right, up all under the plastics or ceramic material casing of the airtight and electric insulation of water seal; At box house, lay amortization material, at box outer surface, make the liquid storage micro groove on superfine and densely covered surface, below base, install soft rubber and support beam.During shower, casing is directly placed near the accomodation ground in shower position.
Such first is that the noise elimination effect of interior deadener and the buffer damping effect of rubber beam and firm ground supports have just alleviated casing greatly because hanging the unsettled vibration causing and resonance noise;
The second, thus shower process splash and drop to water droplet on casing and can in the liquid storage micro groove of tank surface, form continuous moisture film noise is effectively absorbed and reflected, this can further eliminate and weaken the machine running noises spreading out of from casing; If necessary, noise reduction effect is more remarkable also can be covered with wet towel in tank surface during shower;
The 3rd, due to box height 40 centimetres of left and right only, and people's ear height when shower is about 150 centimetres, according to acoustics transfer principle, the noise finally spreading out of by liquid film is when the distance more than this meter arrives intelligent's ear, acoustic pressure can drop to 10 left and right of initial value from the numerical value when the tank surface, acoustic pressure (A sound level) can decline 4 decibels at least;
