Description
Technical field
The present invention relates to a kind of electricity or combustion gas accumulator water heater and a kind of flange that is used for described water heater.
Technical background
Because the present invention to electric accumulator water heater advantageous particularly, therefore describes with reference to up-to-date electric accumulator water heater.
The outlet pipe that this accumulator water heater is furnished with casing, inserts the cold water inlet of this water heater bottom and be used for obtaining from the topmost of this casing hot water.
Usually can be provided with and be used to check and the removable flange of maintenance work, and substantially all be provided with this flange in the electric accumulator water heater.
In the electricity accumulator water heater, the corrosion protection equipment that constitutes by magnesium anode usually that one or more resistance is installed on the described flange, is provided with the thermostat of one or more temperature sensors and can selects to install.
Modal flange is circular and is installed on the outside of this casing; Yet it also can be ellipse, and is installed on the outside or is installed on the dsah-pot (surge tank).
This resistance that is installed on the flange is suitable for when cold water enters it being heated, those resistance can be snakelike or screw type resistance, thus need enough helix length and the flange that this resistance is installed can be inserted and takes out between obtain compromise scheme.
This thermostat comprises one or more temperature sensors, and described temperature sensor is suitable under normal work period and situation about breaking down for guaranteeing that safety measures the water temperature in this casing.
The most basically, thermostat comprises the electrical contacts (cut-off type or switch type) that the element by sensing temperature starts, and the equipment of regulating threshold temperature.
The employed now thermostat of water heater can be rod-type, ball formula (bulb-type) or electronic type or Ke Lisen (clickson) formula.
The operation principle of rod thermostat is two kinds of material coefficient of thermal expansion coefficient differences, and it is made of the brass rod of band iron-nickel alloy core usually.
Ball formula thermostat is based on hydraulic principle work, the liquid that changes because this ball formula thermostat contains that volume varies with temperature.
The variation of this volume makes bellows expand, and the bellows of expansion start electrical contacts.
In the electronic type thermostat, and temperature sensor (can be the NTC sensor, or more uncommon PCT sensor) be included in the resistivity conductor that changes under the temperature action, and under measured temperature action, act on the logic circuit on the current switch.
At last, in the Ke Lisenshi thermostat, sensing/starting element is formed by so-called " bimetallic " plectane, and this plectane is made of the tablet that two-layer thermal coefficient of expansion has the different metal of suitable difference.
Be formed with projection on this plectane, when reaching predetermined temperature, described projection its spill of overturning immediately, the distortion of described projection is to produce owing to the thermal expansion of two layers is different.
For rod-type, ball formula or electronic type thermostat, temperature sensor can be inserted in the suitable sheath, directly immerse in the water of casing, and generally be connected with the flange of this water heater.
Guaranteed accurately and regulated apace this temperature in the water with this temperature sensor immersion casing.
Yet these solutions have problems.
At first, sheath has increased manufacturing cost.
And this sheath further hinders flange is installed on the casing that one or more resistance and optional corrosion protection equipment are installed.
This sheath makes and is difficult to use multiple shape resistance, more particularly, because the existence of this sheath can hinder this flange to insert in this casing, thereby can not use L shaped resistance.
Described problem is particularly evident for the flange that is mounted on the dsah-pot, and these flanges need the more freedom degree to allow complicated moving for installation.
The DE10062936 document shows a kind of water heater flange of injection mo(u)lding, and it holds in single part basically water is heated required various device, comprises the sheath of the temperature sensor that is used for thermostat.This sheath is orthogonal to this flange surface and inner outstanding towards this water tank as common.This sheath changed is its manufacturing process but does not change its conventional shape, and the unresolved above-mentioned relevant whole flange defective of installing.In addition, according to of the present invention open, should understand in many cases itself and nonessential.
For ball formula or electronic type thermostat, substitute mode as this sheath, this temperature sensor can insert so-called " connecting piece (tie) ", and described connecting piece just is difficult to the position that touches again near the outer surface of this casing after normally in a single day this water heater is made.
This solution also has some shortcomings.
Owing to must insert optional feature,, thereby increase manufacturing cost as connecting piece.
The plane surface that the circular portion of this temperature sensor also can't be placed to casing forms thermo-contact closely.
In addition, must change under the situation of this thermostat, it is difficult removing the temperature sensor that is somebody's turn to do " connecting piece ", or impossible.
In the DE1156518 document, adopt fuse as the safety thermostat in the electric heater.In order to guarantee that this safety thermostat is not subjected to water temperature, perhaps at the water tank sky situation under not be contained on the tank wall in the groove that this casing is charged into, by the influence of air themperature, this fuse to contact this electrical equipment.If the scope of this temperature sensor, then can be damaged the such groove of temperature sensor near electrical equipment that make for checking the scope of water temperature.In addition, temperature sensor is installed on the tank wall and is not installed on the flange that can touch, do like this and impracticable, because can't keep in repair and/or replace parts.
The Ke Lisenshi thermostat is to use the simplest, and its temperature sensor can directly be positioned over and face-flange surface position contacting, be convenient near and need not the sheath of box house.
Regrettably, the adjustment precision deficiency of the thermostat of this solution.
In fact, the suitable inaccuracy of this Ke Lisenshi thermostat, and thermal inertia is higher; Especially, the bimetallic plectane that constitutes sensing/starting element can't be placed to flange and form thermo-contact closely, and the water temperature that will be controlled is passed through its transmission just.
Especially, when the temperature sensor of Ke Lisenshi thermostat detects water temperature and drops under the operating temperature, the delay of some minutes be arranged, so just increase the time that returns to the temperature that is pressed for.
During this period of time, do not remind hot water to lack by suitable alarm lamp, making the user can't understand this problem still is to cause owing to this water heater damages owing to heating water.
Summary of the invention
The present invention's purpose particularly solves the above problem for solving the existing existing at least a portion problem of electric accumulator water heater.
