Description
Technical field
The utility model relates to a kind of electric heating tube, in particular for the domestic, electric water heater that has overtemperature protection system or the electric heating tube in the electric hot water tap.
Background technology
According to the regulation in the relevant domestic, electric water heater standard, domestic, electric water heater must be provided with the safety guard under abnormal operating state, and promptly electric heating tube can be cut off the electricity supply under the anhydrous dry-fire condition of electric heater immediately, and irrecoverable.
Water heater is the critical piece of domestic, electric water heater, as shown in Figure 1, common water heater generally includes shell 4 and the electric heating tube 1 that is installed in the shell 4, two thermostats that are connected in series with electric heating tube are housed on the shell 4 of the water heater of prior art usually, one is can automatically reset water temperature thermostat 6, is used to regulate and control the leaving water temperature of water heater, when the water temperature in the water heater reaches design temperature, the electric heating tube power supply is cut off in the automatic disconnection of water temperature thermostat; When the water temperature in the electric heater drops to design temperature when low slightly, the water temperature thermostat automatically resets, again with the electric heating tube power connection, and so periodic duty.Another is for the anti-dry heating temperature controller 5 of hand-reset; be used to protect water heater; at the water temperature thermostat malfunctioning or other reason occur in the water heater anhydrous and electric heater continues under heating so that the dry-fire condition, when the water heater housing reaches design temperature, the anti-dry heating temperature controller automatic disconnection; cut off the electric heating tube power supply; reach the purpose of protection water heater, after the temperature of water heater housing descended, anti-dry heating temperature controller did not automatically reset; reactivate as needs, can reset manually.
Automatic water temperature control and overheat protective technology have been arranged; water heater adopts the plastic housing urceolus usually; electric heating tube places in the plastics urceolus; and the shortcoming of plastics urceolus maximum is that temperature capacity is relatively poor; when temperature reaches certain value; plastics can melt in deliquescing, cause urceolus to damage, even the danger of smoldering, burning is arranged.
In the prior art; it also is insecure on the plastic casing that the anti-dry heating temperature controller of water heater is installed on; because after dry combustion method appears in electric heating tube; heat will be delivered to plastic casing and anti-dry heating temperature controller simultaneously by the air in the plastics urceolus; at this moment plastic casing has born very high temperature, has occurred ruckbildung at least, though this overheated automatic resist technology of anti-dry heating temperature controller is arranged; unlikely generation security incident, but this plastic casing generally can not be reused again.
The innovation and creation content
The purpose of this utility model is that the electric heating tube that existing electric heater is used is improved; make this electric heating tube have heat conducting bar; water heater with this electric heating tube; the anti-dry heating temperature controller that is connected in series with electric heating tube is installed on the heat conduction rod end; when dry combustion method appears in electric heating tube; the electric heating tube power supply can be in time cut off, the effect of protection water heater can be effectively played.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of electric heating tube with heat conducting bar, by 1 or form more than 1 U-shaped electrothermal tube, connect with a connecting plate near the electrode tip of U-shaped electrothermal tube, an end and the U-shaped electrothermal tube of a heat conducting bar are welded to connect, and the other end of heat conducting bar has an anti-dry heating temperature controller connector.
A kind of electric water heater, include plastic casing and be fit in the plastic casing 1 or more than 1 U-shaped electrothermal tube, connect with a connecting plate near the electrode tip of U-shaped electrothermal tube, one end and the U-shaped electrothermal tube of one heat conducting bar are welded to connect, the other end of heat conducting bar has an anti-dry heating temperature controller connector, and the anti-dry heating temperature controller connector of heat conducting bar is stretched out outside the plastic casing.
The electric heating tube of another kind of band heat conducting bar is made up of a spirality electrothermal tube, and an end and the spirality electrothermal tube of a heat conducting bar are welded to connect, and the other end of heat conducting bar has an anti-dry heating temperature controller connector.
Another kind of electric water heater, include plastic casing and be fit into an interior spirality electrothermal tube of plastic casing, one end and the spirality electrothermal tube of one heat conducting bar are welded to connect, the other end of heat conducting bar has an anti-dry heating temperature controller connector, and two electrodes of spirality electrothermal tube and the anti-dry heating temperature controller connector of heat conducting bar are stretched out outside the plastic casing.
Use when adding device group structure electric heater by electric hot water of the present utility model, anti-dry heating temperature controller connector at heat conducting bar is installed anti-dry heating temperature controller, with the water temperature thermostat is installed at plastic casing, add control assemblys such as control circuit board and water flow switch are set in water heater.
The safeguard protection principle of this electric heater is:
Under the normal operating position of electric heater, electrothermal tube provides power supply by control circuit board through water temperature thermostat and anti-dry heating temperature controller, when the water temperature in the electric water heater reaches design temperature, the automatic disconnection of water temperature thermostat, cut off the electric heating tube power supply, when the water temperature in the electric heater drops to design temperature when low slightly, thermostat automatically resets, again with the electric heating tube power connection.Malfunctioning or other reason occurs in the electric water heater anhydrous and electric heating tube continues under heating so that the dry-fire condition owing to the water temperature thermostat; the temperature of electric heating tube raises rapidly; heat conducting bar transfers heat to anti-dry heating temperature controller (at this moment electric water heater's housing does not also reach too high temperature) rapidly; arrive the anti-dry heating temperature controller automatic disconnection of design temperature; cut off the electric heating tube power supply; reach the purpose of timely protection electric heater; after the temperature decline Deng electric water heater's housing; anti-dry heating temperature controller does not automatically reset; reactivate as needs, can reset manually.Because the effect of heat conducting bar, this electric water heater's housing can be reused usually.
Be compared with the prior art, the utility model has following characteristics and progress:
The utility model is simple in structure, practical, adopts electric heater of the present utility model, and the dry combustion method of electric heating tube can be controlled early, and the electric water heater's who adopts plastic casing anti-dry performance is strengthened greatly.
