Storage-type electric water heater
Technical field: the utility model relates to a kind of storage-type electric water heater.
Background technology: in the prior art, the temperature temperature detection point of storage-type electric water heater is arranged on the middle part of inner bag, is detected the water temperature at temperature detection point place by temperature probing tube and controls heating tube on/off electricity, makes water temperature reach design temperature.And water inlet is in the bottom of inner bag, in use, cold water enters the bottom of inner bag, and along with the cold water that enters in the inner bag increases gradually, the cold water area volume constantly enlarges on the temperature tube that expands the inner bag middle part to, drop to and be lower than when setting value when detecting temperature tube place water temperature, heating tube just is activated heating work, and at this moment, existing a large amount of cold water enter inner bag, the startup heating of heating tube is moved by postpone, rapidly heat make-up hot water.This causes the hot water supply of electric heater to reduce easily, even the not enough phenomenon of hot water occurs, influences the hot water delivery rate of electric heater.When the inflow temperature of cold water hangs down, influence especially obvious.For overcoming these defectives, we develop the structure of storage-type electric water heater.
Summary of the invention: technical problem to be solved in the utility model is that a kind of storage-type electric water heater will be provided, it can improve the sensitivity that electric heater detects inflow temperature, the reaction speed that heating tube starts when having improved moisturizing, it is more timely that hot water is replenished, and effectively improves the hot water delivery rate of electric heater.
The technical scheme that its technical problem that solves the utility model adopts is: it comprises inner bag and is arranged on the interior main heating tube of inner bag, main heating tube electrically connects with the circuit controller of its break-make of control, inner bag is provided with water inlet pipe and outlet pipe, wherein water inlet pipe and/or outlet pipe are provided with the water pipe temperature element that detects the current temperature, and water pipe temperature element and circuit controller electrically connect.
Described water inlet pipe and/or outlet pipe are provided with tube connector, and the water pipe temperature element is installed on the body.
Described tube connector is provided with side opening, and water pipe temperature element one end passes the inner chamber that side opening puts in tube connector, is provided with sealing ring between side opening and the tube connector temperature element.
Described sealing ring is placed on the water pipe temperature element.
Also be provided with temperature probing tube in the described inner bag, temperature probing tube is provided with the inner bag temperature element that detects the inner bag water temperature, and inner bag temperature element and circuit controller electrically connect.
Described temperature probing tube is arranged on top or the middle part or the bottom of inner bag.
The inherent outlet pipe outer periphery of described inner bag is equipped with the sleeve of both ends open, is provided with auxiliary heating tube between outlet pipe and the sleeve, and auxiliary heating tube and circuit controller electrically connect.
The utility model is compared the beneficial effect that is produced with background technology:
1, because the utility model is provided with temperature element at water inlet pipe and/or outlet pipe, improved the sensitivity that electric heater detects inflow temperature, the reaction speed that heating tube starts when having improved moisturizing, it is more timely that hot water is replenished, and effectively improves the hot water delivery rate of electric heater.

The specific embodiment:
As depicted in figs. 1 and 2, this storage-type electric water heater comprises inner bag 1 and the main heating tube 4 that is arranged in the inner bag 1, main heating tube 4 electrically connects with the circuit controller of its break-make of control, inner bag 1 is provided with water inlet pipe and outlet pipe, wherein water inlet pipe and/or outlet pipe are provided with the water pipe temperature element that detects the current temperature, and water pipe temperature element and circuit controller electrically connect.Also be provided with temperature probing tube 2 in the inner bag 1, temperature probing tube 2 is provided with the inner bag temperature element that detects inner bag 1 water temperature, and inner bag temperature element and circuit controller electrically connect, and temperature probing tube 2 is arranged on top or the middle part or the bottom of inner bag 1.
For making things convenient for I﹠M, water inlet pipe and/or outlet pipe are provided with tube connector 3, and the water pipe temperature element is installed on the tube connector 3.As shown in Figure 3 and Figure 4, tube connector 3 is provided with side opening 31, and water pipe temperature element one end passes the inner chamber that side opening 31 puts in tube connector 3, is provided with sealing ring 6 between side opening 31 and the water pipe temperature element, and sealing ring 6 is placed on the water pipe temperature element.
Inner bag 1 inherent outlet pipe outer periphery is equipped with the sleeve 7 of both ends open, is provided with auxiliary heating tube 5 between outlet pipe and the sleeve 7, and auxiliary heating tube 5 electrically connects with circuit controller.Heat in the small space that auxiliary heating tube 5 forms between sleeve 7 and outlet pipe, water temperature in the small space is raise rapidly, the hot water come-up, cold water is from the additional sleeve 7 that enters of the opening of sleeve 7 bottoms, the inside and outside circulating water flow that forms of small space, float to around the mouth of pipe of outlet pipe on the hot water of come-up is direct, and preferentially enter outlet pipe, use for the user, thereby make electric heater just can provide high-temperature-hot-water, play fast heat effect, improve hot water delivery rate without the water of the whole inner bag of preheating, shorten preheating time, reduce energy loss.
Under the energising situation, duty combination of the present utility model is as follows:
1. when not using hot water, when recording water temperature, the inner bag temperature element is lower than its set temperature value, circuit controller starts main heating tube work separately or starts main heating tube simultaneously and auxiliary heating tube work according to the function that the user sets, and reaches set temperature value up to water temperature;
2. use the hot water time greater than the circuit controller setting-up time, as when taking a shower, auxiliary heating tube work, when the water temperature that records when inner bag temperature element or arbitrary water pipe temperature element is lower than its set temperature value, circuit controller starts main heating tube work, thereby main heating tube and auxiliary heating tube are heated simultaneously, otherwise have only auxiliary heating tube to work independently, record water temperature in the inner bag up to the inner bag temperature element and reach the safety margins temperature value and just stop all heating works.
3. when using the hot water time to be not more than the circuit controller setting-up time, as when washing one's hands, only auxiliary heating tube work.
