Abstract
The utility model discloses an instant electric water heater with a waste heat recovery system. The instant electric water heater comprises an instant electric water heater and the waste heat recovery system. A waste heat collection device and a cold water preheating pipeline are arranged in the waste heat recovery system, and exchange heat with each other. The cold water preheating pipeline is inserted into the waste heat collection device. The waste heat collection device is connected and provided with a port for collecting used hot water. A water inlet of the cold water preheating pipeline is connected with a water inlet of a tap water pipe, and a water outlet of the cold water preheating pipeline is connected with a water inlet of the instant electric water heater. A water outlet of the instant electric water heater is connected with a water utilization terminal interface. The waste heat recovery system is arranged at the water inlet end of the instant electric water heater to preheat inflow to increase the inflow temperature of the instant electric water heater, and an electronic board performs calculation to reach set effluent temperature only by outputting lower power, so that the aim of energy saving is fulfilled, the utilization rate of energy sources is increased, and the energy sources are saved.
Description
Technical field
The utility model relates to a kind of electric heater, relates in particular to a kind of instant electric water heater with residual neat recovering system.
Background technology
The continuous consumption of present global non-renewable resources, energy crisis constantly enlarge stretches, and particularly China's per capita resources occupancy volume is considerably less; In order to realize energy-saving and emission-reduction; Reduce the discharging of carbon, improve people's quality of life, so people need low, the product of energy-conserving and environment-protective more of power load.At present people are in using the hot water bathing process, are not very high to the utilization rate of heat in the hot water, and a large amount of heats in the hot water have all been wasted, and cause the waste of resource.
Summary of the invention
The utility model purpose provides a kind of heat that can reclaim in the used hot water carries out the band residual neat recovering system of preheating to water inlet instant electric water heater.
The utility model adopts following scheme to realize: the instant electric water heater of band residual neat recovering system; It comprises instant electric water heater and residual neat recovering system; Be provided with the residual heat collection device and the cold water preheating pipeline that carry out heat exchange in the residual neat recovering system; Cold water preheating pipeline is set in the residual heat collection device, and the residual heat collection device is connected with collects the interface that uses superheated water, and the water inlet of cold water preheating pipeline connects the water inlet of running water pipe; The delivery port of cold water preheating pipeline connects instant electric water heater's water inlet, and instant electric water heater's delivery port connects the water terminal interface.
Be provided with Electronic Control plate, temperature controller with manual reset and the temperature controller that automatically resets among the said instant electric water heater, be respectively equipped with inflow temperature sensor and leaving water temperature sensor on instant electric water heater's water inlet and the delivery port.
Residual heat collection device in the said residual neat recovering system and cold water preheating pipeline adopt copper pipe or stainless steel tube.
The beneficial effect of the utility model is: adopt said structure; When the user opens the application terminal (like shower house, bathtub, washbowl etc.) that connects instant electric water heater's delivery port when using hot water, get into from the water inlet of the cold water preheating pipeline of cold water from residual neat recovering system of running water pipe, through residual neat recovering system heat exchange preheating; The delivery port of the cold water preheating pipeline from residual neat recovering system flows into instant electric water heater's water inlet; The water flow sensor that is located on instant electric water heater's water inlet detects into water signal, transmits signal for the Electronic Control plate, lets the Electronic Control plate start working; At this moment the temperature sensor that is located on instant electric water heater's water inlet and the delivery port will be gathered corresponding temperature; And pass to the Electronic Control plate, calculate the output of control instant electric water heater heating bar power through the Electronic Control plate; Reach the leaving water temperature of setting with minimal power output, and keep effluent temperature constancy.
The utility model is provided with residual neat recovering system preheating water inlet at instant electric water heater's water inlet end, and hot water can be provided fast, improves energy utilization rate, energy savings.
Description of drawings
Combine accompanying drawing that the utility model is done further elaboration at present:
Fig. 1 is the instant electric water heater's of the utility model band residual neat recovering system a structural representation.
The specific embodiment
As shown in Figure 1; The utility model comprises instant electric water heater 1 and residual neat recovering system 2; Be provided with the residual heat collection device 21 and cold water preheating pipeline 22 that carry out heat exchange in the residual neat recovering system 2; Cold water preheating pipeline 22 is set in the residual heat collection device 21, and residual heat collection device 21 is connected with collects the interface that uses superheated water, and the water inlet of cold water preheating pipeline 22 connects the water inlet 3 of running water pipe; The delivery port of cold water preheating pipeline 22 connects instant electric water heater 1 water inlet 11, and instant electric water heater 1 delivery port 12 connects water terminal interface 4.
Be provided with Electronic Control plate, temperature controller with manual reset and the temperature controller that automatically resets among the said instant electric water heater 1, be respectively equipped with inflow temperature sensor and leaving water temperature sensor on instant electric water heater 1 water inlet 11 and the delivery port 12.
Residual heat collection device 21 in the said residual neat recovering system 2 adopts copper pipe or stainless steel tube with cold water preheating pipeline 22.In order to increase heat exchanger effectiveness, make instant electric water heater 1 water inlet can preheating more abundant, the circulation line in the residual neat recovering system 2 can be made double-deck up and down, and shape can be made structures such as fan-shaped, three-back-shaped.
When the user opens application terminal (like shower house, bathtub, washbowl etc.) the use hot water of water terminal interface 4; Because people use hot water generally in 40 deg.c usually; The water temperature of the hot water after the use still remains on 35 deg.c; A lot of heats all are discharged in the sewer from interface and have gone, and have wasted significant amount of energy.Connection through residual heat collection device 21 in the residual neat recovering system 2 collect use superheated water interface with this part heat recovery; The heat exchange waste heat is carried out in water inlet to instant electric water heater 1; Improve instant electric water heater 1 inflow temperature, calculate, only need the lower power of output through the Electronic Control plate; Just can reach the leaving water temperature of setting, thereby reach purpose of energy saving.
