Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing in describing below only is some embodiment of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work property, can also obtain other accompanying drawing according to these accompanying drawings.
The structural representation of the storage-type electric water heater that Fig. 1 provides for the utility model embodiment.
The specific embodiment
To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model embodiment provides a kind of storage-type electric water heater, and is as shown in Figure 1, and this water heater comprises:
In the utility model embodiment, heating tube 2 is arranged in the inner bag 1, and anti-dry sensor 3 is arranged on the heating tube 2, and anti-dry sensor 3 is used for detecting the temperature of said heating tube 2, and controller 4 is arranged on outside the said inner bag 1.When heating tube was in water, because the thermal conductivity factor of water is higher, heating tube was when the energising heating; The heat of heating tube can be very fast be delivered in the water, the temperature on heating tube surface remains on reduced levels (when stablize about 100 degree), does not have water and work as inner bag; Be that heating tube is exposed to when energising is heated in the air; Less because of the thermal conductivity factor of air, the heat of heating tube distributes very slow, the surface temperature of heating tube can sharply rise (when stablize 700 spend about).Therefore, can judge that through place anti-dry sensor detector tube table temperature on the heating tube surface heating tube is in water or in the air.
In the storage-type electric water heater that the utility model embodiment provides, water gets in the inner bag 1 through water inlet pipe 7, and transfers out inner bag 1 through heating tube 2 heating backs by outlet pipe 6; Anti-dry sensor 3 is arranged on the heating tube 2; Be used for monitoring in real time the state of temperature of heating tube 2, and the state of temperature signal is sent to controller 4, controller 4 is connected with the switching system of heating tube 2; The thermal conductivity factor that controller 4 is judged heating tube 2 surrounding mediums according to the temperature or the temperature rise rate of heating tube 2; And then to judge be which kind of medium (like water or air), and when the temperature of heating tube 2 is too high (water level in the inner bag 1 is lower than heating tube 2), controller 4 control heating tubes 2 are closed.
The storage-type electric water heater that the utility model embodiment provides; Detect the temperature of heating tube through the anti-dry sensor and judge whether the water level in the inner bag is low excessively; And then pass through the opening and closing that controller is controlled heating tube, and preventing that the temperature of heating tube is too high, package unit is simple and reliable for structure; And production technology is simple, and cost is lower.
Further; In the utility model embodiment, controller 4 comprises: be used for judging according to the temperature of the detected heating tube of said anti-dry sensor whether said heating tube is in the dry combustion method judge module of dry-fire condition and is used for when said dry combustion method judge module judges that said heating tube is in dry-fire condition, controlling the dry combustion method control module that said heating tube is closed.The anti-dry sensor detects the temperature of said heating tube; The dry combustion method judge module calculates the heating rate that obtains heating tube 2 according to the real time temperature of heating tube 2 or according to real time temperature; The dry combustion method judge module judges that according to the real time temperature or the heating rate of heating tube 2 heating tube is in water or in air; Heating rate like heating tube 2 is very high, judges that promptly heating tube 2 is exposed in the air, promptly is in dry-fire condition.Dry combustion method control module control heating tube when the dry combustion method judge module judges that heating tube is in dry-fire condition is closed.
Further, in the utility model embodiment, said anti-dry sensor 3 detects the temperature of said heating tube 2; When if said anti-dry sensor 3 detects said heating tube 2 temperature and spends more than or equal to 200, said controller 4 control heating tubes are closed; When if said anti-dry sensor 3 detects said heating tube 2 temperature and spends less than 200, said controller 4 control heating tubes 2 are opened.The temperature of heating tube 2 is remained on about 200 degree, guarantee the security reliability of water heater.
Further, the water heater that the utility model embodiment provides also comprises: inner bag 1; Said heating tube 2 is arranged in the said inner bag 1; Said controller 4 is arranged on outside the said inner bag 1, is provided with sensor sleeve 5 in the said inner bag 1, and said wall of inner container is provided with the hole that only supplies said sensor sleeve 5 to pass; Said sensor sleeve 5 one ends are arranged on said heating tube 2 surfaces; The other end is communicated with described hole, and said anti-dry sensor 3 is arranged in the said sensor sleeve 5, is provided with connecting line 9 in the said sensor sleeve 5; Said connecting line two ends are connected with controller 4 with said anti-dry sensor 5 respectively, and anti-dry sensor 3 carries out the signal transmission with controller 4 through connecting line 9.Anti-dry sensor 3 is installed in the sensor sleeve 3, makes that the water in the inner bag 1 can't touch anti-dry sensor 3 and connecting line 9, guarantees the operate as normal of anti-dry sensor 3.
The storage-type electric water heater that the utility model embodiment provides; Judge through being arranged on temperature or the heating rate that anti-dry sensor in the sensor sleeve detects the heating tube surface whether the water level in the inner bag is low excessively, and then the opening and closing through the controller control heating tube that all is connected with anti-dry sensor and heating tube, realization is to the real-time monitoring of the water level of inner bag; The temperature that prevents heating tube is too high; Package unit is simple and reliable for structure, and production technology is simple, and cost is lower.
The above; Be merely the specific embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any technical staff who is familiar with the present technique field can expect changing or replacement in the technical scope that the utility model discloses easily, all should be encompassed within the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion with the protection domain of said claim.
