Further, described check-valves is located between the interface of hot water and cold water interface in the hot water supply centre of water heater distal-most end.
Further, the controlled circuit control of described water pump.
Described water pump and control circuit thereof are located in the housing, form the water saving water recovery apparatus, and housing is provided with the control panel of control water pump start-stop.
Further, the control circuit of described water saving water recovery apparatus comprises for the reception of wireless signals unit that receives remote controller signal, is used with remote controller, and the control water pump is opened.
The utlity model has following beneficial effect:
1. the utility model water saving water recovery apparatus only is comprised of control circuit and water pump two parts of control water pump start-stop, and the start and stop duration of runs of control circuit control water pump, parts are simple, and installation procedure is simple and easy.
2. the utility model operation is upper adopts manually and remote control combines, and the control panel of water saving water recovery apparatus has intuitively time control and regulation and has memory function, and remote controller adopts one-touch button control unlatching, operates very simple and convenient.
3. the hot water joint that the utility model will be from the hot water supply centre of water heater distal-most end (such as washbowl, wash nappy etc.) is connected with check-valves with the cold water joint, and installation procedure is simple and easy.
4. the utility model only needs the cold water access port of water saving water recovery apparatus access water heater is got final product.Simple and convenient, do not affect user's normal use.Therefore, practicality is good, and popularization is wide.
Description of drawings
Fig. 1 is system's scheme of installation of embodiment, and the thick line section is hot water pipeline among the figure, and the fine rule section is cold water pipes.
Fig. 2 is the embodiment water recovery apparatus internal structure schematic diagram of economizing on water.
The specific embodiment
Principle of the present utility model is that the filling method is taken out in the control of employing time, namely presets the duration of runs of water pump, by water pump the cold water that retains in the hot-water line is extracted out, replenishes simultaneously hot water and enters.When opening the hot water demand, because hot-water line is full of hot water, hot-water line flows out hot water at once.General domestic consumer's pump operation time is about 1 minute, can use hot water, not waste water resource.This control method is simple and practical, needn't adopt the accessories such as sensor, magnetic valve.In addition, the utility model building block is simple, and fault rate is extremely low, and practicality is good, is convenient to penetration and promotion.
Below in conjunction with drawings and Examples the utility model is described in detail.
