Embodiment
Fig. 2 illustrates a kind of structural representation of storage-type electric water heater according to an embodiment of the invention, and Fig. 3 illustrates the structural representation of the electric heating tube among Fig. 2.Please refer to Fig. 2 and Fig. 3, storage-type electric water heater 200 comprises can be in order to the aqua storage tank 300 of water storage and the electric heating tube 400 that can heat the water that is stored in the aqua storage tank.Aqua storage tank 300 has water inlet 310 and delivery port 320, and wherein this water inlet 310 is adjacent to the bottom 302 of aqua storage tank 300, and this delivery port 320 then is adjacent to the top 304 of aqua storage tank 300.In this embodiment, electric heating tube 400 can erectly be assembled in the top 304 of aqua storage tank 300.Yet in other unshowned embodiment, electric heating tube 400 can also erectly be assembled in the bottom 302 or the sidewall 306 of aqua storage tank 300.
These connectors 420 for example are nuts, and it is connected to these linkage sections 412, so that body 410 can be locked in the top 304 of aqua storage tank 300 by these connectors 420.In addition, these leads 440 are disposed at respectively in these linkage sections 412, and heater coil 430 then is disposed at bringing-up section 414.These leads 440 are connected to the opposite end of heater coil 430, and pass these linkage sections 412 and passed by the opposite end of body 410, so that heater coil 430 can be electrically connected at the power supply (not shown) by these leads 440.
The temperature of the water in being stored in aqua storage tank 300 is crossed when hanging down, and power supply can be to electric heating tube 400 power supplies, so that heater coil 430 and these leads 440 heatings.At this moment, heater coil 430 can be delivered to the water that is stored in the aqua storage tank 300 by bringing-up section 414 and these linkage sections 412 respectively with the heat energy that these leads 440 are produced, so that the water in the aqua storage tank 300 is heated to a preset temperature.
In this embodiment, heater coil 430 can be the nickel filament coil, and these leads 440 then can be the leads made from nichrome, and these leads 440 can form in the opposite end of heater coil 430 integratedly.And the unit caloric value that is wound in the heater coil 430 of coiled type can be greater than the unit caloric value of these leads 440, and wherein the unit caloric value for example is the caloric value of unit length.Yet in other unshowned embodiment, heater coil 430 can be the nickel filament coil, and these leads 440 can be copper conductors or with the made lead of other electric conducting material.
In general, the density of hot water can be less than the density of cold water, so the higher water of temperature can flow towards the higher level place usually.It should be noted that in this embodiment electric heating tube 400 erectly is assembled in the aqua storage tank 300.Therefore, heater coil 430 can heat the water that is positioned at different water levels by bringing-up section 414 and these linkage sections 412 respectively simultaneously with these leads 440.Wherein, the heater coil 430 that the unit caloric value is bigger can be by the water of bringing-up section 414 heating than low water level, and these less leads 440 of unit caloric value then can be by the water of these linkage section 412 heating higher level.Thus, when 400 pairs of electric heating tubes are stored in water when heating in the aqua storage tank 300, the water that is positioned at different water levels not only can have identical haply rate of rise in temperature, and the water of higher level and also can be less than the temperature difference between the water of low water level and temperature gradient.
In addition, in this embodiment, these leads 440 are designed to respectively to pass from the opposite end of body 410.Thus, assembler is easier to earlier with welding or canoe these leads 440 to be electrically connected at the lead of power supply, and then coats these leads 440 with insulating tape or other insulating material, produces short circuits to avoid these leads 440.Thus, not only be not easy because of these leads 440 produce the useful life that short circuit makes electric heating tube 400 damages or shortens electric heating tube 400, and electric heating tube 400 in the use also can be safer.
Fig. 4 illustrates out the structural representation according to the electric heating tube of another embodiment of the utility model.Please refer to Fig. 4, the structure of the electric heating tube 500 among this embodiment and the structural similarity of the electric heating tube among Fig. 3 400.The two difference is, the bringing-up section 414 of the electric heating tube 400 among Fig. 3 only has a bending part 416, and the bringing-up section 514 of the electric heating tube 500 among Fig. 4 then has a plurality of bending parts 516 (this embodiment graphic in three bending parts only schematically are shown out).
In sum, in the utility model, owing to electric heating tube erectly is assembled in the aqua storage tank, thereby can be in order to heat the water that be positioned at different water levels simultaneously.In addition, the bigger heater coil of unit caloric value can heat water than low water level by bringing-up section, and these less leads of unit caloric value then can heat the water of higher level by these linkage sections.Therefore, when electric heating tube heated being stored in water in the aqua storage tank, the water that is positioned at different water levels not only can have identical haply rate of rise in temperature, and the water of higher level and also can be less than the temperature difference between the water of low water level and temperature gradient.
In addition, these leads are designed to respectively to be passed by the opposite end of body, and therefore not only assembler is easier to these leads are electrically connected at power supply, and these leads also are not easy to produce short circuit.Thus, electric heating tube not only can have long useful life, also can be safer in the use.
Above-described embodiment only is for technological thought of the present utility model and characteristics are described, its purpose is to make those skilled in the art can understand content of the present utility model and implements according to this, rather than is used for limiting claim of the present utility model.Every equivalent variations or modification of making according to the spirit that the utility model disclosed must be included in the claim of the present utility model.
