Abstract
The utility model relates to an automatic temperature-control water-circulation electric heater for civil use, comprising a water tank with an inlet and an outlet, and electroheating pipes in the water tank. The utility model is characterized in that the pipeline which is connected with the inlet of the water tank is provided with a water injection cup; a water circulating pump is arranged between the water injection cup and the water tank; the outlet of the water tank goes through a radiator whose water return pipe is communicated with the water inlet pipe. The utility model which adopts a small water pump has the advantages that the hot water circulation can be promoted; the heat radiation is homogeneous; the defect of the existing electric heater which adopts the principle of cold and hot water convection, the installation is complex, is overcome; the structure is simple; the cost is low; the installation and the operation are convenient, safe and sanitary; the indoor humidity is not effected, etc.
Description
The utility model belongs to the civilian technology field, specifically a kind of electric heating device.
As everyone knows, people go up to be unable to do without heating installation in the winter time, particularly in our north.At present, our northern most of residential houses also adopt coal to burn a heatable brick bed heating, and this heating mode is wasted time and energy, but also dangerous, has caused certain pollution to living environment.
The purpose of this utility model provides a kind of temperature automatically controlled electric heater that has water circle device.
The purpose of this utility model is achieved in that it includes the water tank of bringing outlet into, electrothermal tube is housed in the water tank, it is characterized in that on the pipeline that connects the water tank entrance point, a water filling cup being set, between water filling cup and water tank, be equipped with a water circulating pump, the delivery port of water tank is by radiator, and its return pipe is connected with water inlet pipe.Above-mentioned electrothermal tube is in parallel with pump motor and connects with temperature controller.During use, after electric current is connected, by temp control switch, the work that makes left by water pump earlier, connects the electrical heating switch, to limiting temperature, the temperature detect switch (TDS) automatic disconnection, electric heater and the work of water pump stop treat that temperature is lower than the temperature of setting, repeat above-mentioned heating work program again, thus guaranteed this heater with the temperature of utensil.
Therefore the utility model has following advantage owing to adopted water circulation, electrical heating, temperature automatically controlled:
1, because electric heater is temperature automatically controlled, adjustable, thus along with the variation of temperature, arbitrarily temperature adjustment, and in the family nobody the time, need only and temperature controller transferred to temperature required, can work automatically.
2, the utility model has adopted little water pump, impels hot water circuit, and heat radiation has evenly overcome and adopted hot water or cold water's convective principles that complicated shortcoming is installed in the past.
3, the utility model also have simple in structure, cost is low, easy to install, safe and reliable, health, do not influence indoor advantages such as temperature.And applied range, as: " hot house " that warm a heatable brick bed, heating installation, warm bed, vegetable grower use etc.
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
Fig. 1 is the utility model structural representation sketch
Fig. 2 is that the A of Fig. 1 is to schematic diagram
Fig. 3 is the utility model circuit theory diagrams
Shown in Fig. 1-3, it by one bring mouthfuls 3 into, the water tank 1 of outlet 4, electrothermal tube 2 is housed in the water tank 1, on the pipeline that connects the water tank entrance point, a water filling cup 6 is set, between water filling cup and water tank, be equipped with a water circulating pump 5, the delivery port of water tank is by radiator, and its return pipe 7 is connected with water inlet pipe.Above-mentioned electrothermal tube is that the heating tube by a 1000W and a 500W composes in parallel, and has hand switch K1, K2 respectively.This electrothermal tube is in parallel with pump motor TW and connects with temperature controller Q.This circuit is to use the secondary switch control heater, and electric current passes through temp control switch earlier after connecting, be lower than below the temperature of qualification, circuit could pass through, and the work that makes left by water pump, desire to think heating,, two heater switch K1, K2 can be connected simultaneously according to required firing rate.To limiting temperature, temperature detect switch (TDS) automatic disconnection, electric heater and the work of water pump stop treat that temperature is lower than the temperature of setting, and temperature detect switch (TDS) is connected again automatically, and water pump and electric heater are started working.Return multiple following also like this and work, guaranteed this heater with the temperature of utensil.
Claims (2)
1, a kind of domestic use of water temperature automatically controlled electric heater that circulates, it includes the water tank of bringing outlet into, electrothermal tube is housed in the water tank, it is characterized in that on the pipeline that connects the water tank entrance point, a water filling cup being set, between water filling cup and water tank, be equipped with a water circulating pump, the delivery port of water tank is by radiator, and its return pipe is connected with water inlet pipe.
2, electric heater according to claim 1 is characterized in that electrothermal tube and pump motor are in parallel to connect with temperature controller again.
