In above-mentioned instant-heating type water heater, this hygrosensor and this controller can be wired connection or wireless connections.
The utility model makes it compared with prior art owing to adopt above technical scheme, can really accomplish instant-heating, can control the temperature of pipeline and the time of heating according to user preferences.This device is realized simple, no matter be electrical heating, coal gas heating, or the water heater of solar energy heating can change into instant-heating by simple improvement.And this device not only can be used as pot-type boiler, and can apply to some big occasions widely, as school, and hospital, hotel or the like.
Description of drawings
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent, below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated, wherein:
Fig. 1 shows the internal structure of the utility model instant-heating type water heater and the external pipe schematic diagram of arranging.
Fig. 2 shows the internal structure after instant-heating type water heater of the present utility model manufacturing finishes.
Fig. 3 shows the arranging of pipeline of conventional water heater.
Fig. 4 shows the control panel of instant-heating type water heater of the present utility model.
The specific embodiment
With reference to illustrated in figures 1 and 2, an embodiment who gets final product immediate heating type water heater 10 of the present utility model has comprised hot-water cylinder 1, hot-water line 2, return duct 3, hygrosensor 4, check valve 5, controller 6 and water pump 7 in inside.In water heater 10 outsides hot water pipeline 22, reflux line 23 and cold water pipes 21 are arranged.Wherein hot-water line 2 one ends of water heater inside connect hot-water cylinder 1, and the other end is connected with the hot water pipeline 22 of outside, is connected with a plurality of water devices 24 (as tap) on the hot water pipeline 22, with hot-water supply.In addition, cold water pipes 21 also is connected to these water devices 24, with supply cold water.Return duct 3 one ends connect hot-water line, and the other end is connected with the reflux line 23 of outside, and reflux line 23 is connected with hot water pipeline 22.Preferably, reflux line 23 is installed in the root of close each water device to avoid the waste of water.
After the user did not use hot water, the water in hot water pipeline 22 and the reflux line 23 began the nature cooling, till the temperature of following external environment condition is identical.The utility model keeps water temperature in the pipeline by the design of temperature detection, pumpback heating.Wherein, Temperature Detector 4 and water pump 7 are set in reflux line 23.
Specifically, after the user was provided with pipe temperature, hygrosensor 4 was started working, and detected return duct 3 interior temperature and sent to controller 6.Controller 6 receives this temperature signal, and when this temperature was lower than the design temperature of user's setting, controller 6 can send the starting mode of pump signal, and indication water pump 7 is started working.Then, water pump 7 is taken out the cold water of reflux line 23 and continuous hot water pipeline 22 the insides, enters hot-water cylinder 1 and reheats.And already heated hot water can flow into hot water pipeline 22 and reflux line 23 from hot-water cylinder 1 automatically under hydraulic pressure, makes the interior water of these pipelines remain on the temperature of setting.The detected temperatures that the hygrosensor 4 that receives once more when controller 6 is sent reaches (promptly being equal to or higher than) when temperature is set, and promptly sends water pump stop signal feed pump 7, and indication water pump 7 quits work.Between hygrosensor 4 and the controller 6, and being connected between controller 6 and the water pump can be wired connection, also can be wireless connections.
With reference to shown in Figure 4, controller 6 has a LCDs 61, a switch 62, two on off state display lamps 63, temperature that device 64 is set.LCDs 61 for example shows temperature in preceding pipeline.Switch 62 makes the user unwanted the time, and after working, go out and spend a holiday or the like, closing controller 6, the instant-heating function of the closing controller 6 of more specifically saying so is to save the energy.But two on off state display lamp 63 display water heater duties.
Temperature is provided with device 64 mediation of going up down button, so that the required design temperature of user to be set.For instance, can be provided with highlyer in the time of winter, can be provided with lowlyer in the time of summer, depend on outside temperature and user's hobby.The temperature that it should be noted that pipeline cannot be provided with than the temperature height of water heater, can report an error by controller 6 and avoid this situation.
In addition, on the return duct between hygrosensor 4 and the hot-water cylinder 1, check valve 5 is set also, 5 on check valve allows water from hygrosensor 4 side direction hot-water cylinder side flow, and this can prevent that hot water from flowing into hygrosensor 4 for 3 li from hot-water cylinder 1 toward return duct, influences the precision of hygrosensor 4.
Therefore, the utility model can make common water heater, becomes one and saves time and the water heater of water resource, brings great convenience to the user.Whenever the user can need hot water, can need not to wait for and directly use.
Another characteristics of the present utility model are simple in structure.Instant-heating type water heater more of the present invention (Fig. 1, Fig. 2) and conventional water heater 30 (typically having hot-water cylinder 31 and hot-water line 32) shown in Figure 3 are as can be known, only need add a return duct and corresponding hygrosensor, water pump during fabrication in water heater inside, and in controller, integrate the control corresponding function.When installing and pipeline arranges, only need externally add a reflux line 23 and get final product, without any need for the switch that adds, winding displacement or the like.Wherein return duct 3 installs when water heater dispatches from the factory with the connector of reflux line 23.More present other design, the used components and parts of the utility model are minimum, the simplest, and therefore, after adding extremely low cost, factory is easy to large-scale production.
Though the utility model discloses as above with preferred embodiment; right its is not in order to limit the utility model; any those skilled in the art; in not breaking away from spirit and scope of the present utility model; when doing a little modification and perfect, therefore protection domain of the present utility model is worked as with being as the criterion that claims were defined.
