Abstract
The utility model relates to an electric heating drinking water machine, comprising an electric water heater, a magnetic valve of water inlet communicated with the electric water heater, and a drinking water tap. The electric heating drinking water machine is mainly characterized in that: the connection pipeline of the drinking water tap is connected with a bypass pipe, which is communicated with the atmosphere; the vent height of the communication position is higher than the water outlet height of the drinking water tap. The utility model can get the electric water heater and the pipeline connected with the electric water heater in a normal pressure state all the time, can thoroughly eliminate explosion incipient fault of the electric heating drinking water machine, and greatly raise reliability of the electric heating drinking water machine, which can get the electric heating drinking water machine safer and more durable. Because the utility model reduces pressurization requirement of the electric water heater and the pipeline, manufacture difficulty and cost of the electric heating drinking water machine are greatly reduced.
Description
Technical field
The utility model relates to electrical heated appliance, particularly the structure of electric heating drinking machine.
Background technology
Electric heating drinking machine all has and is used for the electric water-boiling device that water is boiled, and the water inlet of electric water-boiling device is connected with entering water electromagnetic valve, and delivery port is connected with the drinking-water tap.At present the electric water-boiling device of the energy-saving type electric heating drinking machine in the electric heating drinking machine seal, and electric water-boiling device and connected pipeline all are equivalent to the pressure vessel that seals in the process that energising is heated.For this reason, this electric heating drinking machine all will install pressure safety valve additional.But can not thoroughly eliminate hidden peril of explosion malfunctioning because of temperature controller, that pressure safety valve is malfunctioning or any reason such as electric water-boiling device case material fatigue causes like this.
Summary of the invention
The purpose of this utility model provides a kind of electric heating drinking machine that can thoroughly eliminate hidden peril of explosion.
The utility model is achieved in that electric heating drinking machine comprises electric water-boiling device, the entering water electromagnetic valve that is communicated with electric water-boiling device and drinking-water tap, especially, on the connecting pipe of drinking-water tap, be connected with shunt valve, shunt valve is communicated with atmosphere, is communicated with the delivery port height of the passage height at position greater than the drinking-water tap.Because shunt valve is communicated with atmosphere, therefore guaranteed that electric water-boiling device and connected pipeline all are in atmospheric pressure state all the time, thoroughly eliminated hidden peril of explosion, and the difference in height between passage and the drinking-water tap delivery port then plays the effect that anti-sealing flows out from shunt valve.
The utility model has the advantages that the reliability that has improved electric heating drinking machine greatly, make electric heating drinking machine safer durable, and, therefore also greatly reduce the manufacture difficulty and the cost of electric heating drinking machine owing to the requirement of withstand voltage that has reduced electric water-boiling device and pipeline.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the structural representation of embodiment 2.
The specific embodiment
Referring to Fig. 1, entering water electromagnetic valve 2 and drinking-water tap 3 that electric heating drinking machine comprises electric water-boiling device 1, is communicated with electric water-boiling device.Be connected with shunt valve 4 on the connecting pipe of drinking-water tap, shunt valve is communicated with atmosphere.As the passage that is communicated with atmosphere, mouth of pipe height is greater than the delivery port height of drinking-water tap with the top mouth of pipe of shunt valve for present embodiment.When entering water electromagnetic valve 2 was opened, the difference in height between the mouth of pipe and the leading delivery port of drinking-water made water can not flow out from shunt valve 4, and can drink this moment from tap 3 water intakings of drinking water.When entering water electromagnetic valve 2 was closed, electric water-boiling device 1 energising was heated to the water boiling, and shunt valve 4 has guaranteed that electric water-boiling device and connected pipeline are in atmospheric pressure state all the time, have thoroughly eliminated hidden peril of explosion.Numbering 5 among the figure is heat exchangers, makes the water inlet of electric water-boiling device 1 and water outlet carry out heat exchange, plays energy-conservation effect.
Because hydraulic pressure is all higher from the beginning, therefore only rely on the passage of shunt valve and the difference in height between the leading delivery port of drinking-water to prevent that sealing flows out from shunt valve, need very high shunt valve, for the ease of implementing, also level sensor 6 can be set in shunt valve 4, level sensor constitutes the gauge tap of entering water electromagnetic valve 2.When the water level in the shunt valve 4 surpasses when requiring, can close entering water electromagnetic valve 2 by level sensor 6, and when water level descends, can open entering water electromagnetic valve 2 by level sensor 6 again, guarantee the leading normal use of drinking water.Concrete control circuit between level sensor and the entering water electromagnetic valve can be from selecting for use the known various water-level control circuits at present.
The water level control mode also can adopt pressure controling mode.Referring to Fig. 2, in the water stream channel after entering water electromagnetic valve 2, pressure switch 7 is set, and constitutes the gauge tap of entering water electromagnetic valve 2 with pressure switch 7 in lower position.Pressure switch can detect the hydraulic pressure in the pipeline, and then detects the SEA LEVEL VARIATION in the shunt valve 4, requires if the water level in the shunt valve 4 surpasses, pressure switch cuts out entering water electromagnetic valve 2, and when water level descended, pressure switch was opened entering water electromagnetic valve 2, guaranteed the normal use of drinking-water tap.Described " water stream channel after the entering water electromagnetic valve " comprises electric water-boiling device, heat exchanger and each bar pipeline.Concrete control circuit between pressure switch and the entering water electromagnetic valve can be from selecting for use the known various pressure control circuits at present.
For fear of in the process of opening the water intaking of drinking-water tap, cause the entering water electromagnetic valve frequent movement because of the SEA LEVEL VARIATION in the shunt valve is too fast, also can on shunt valve 4, connect container 8 as shown in Figure 1, 2.Container 8 plays the buffer memory effect, and the SEA LEVEL VARIATION speed in the shunt valve 4 that can slow down has been avoided magnetic valve 2 frequent movements, has prolonged the service life of magnetic valve.
As further improvement, also can be at container 8 outer wrapping insulation materials.So can prevent to reduce the leaving water temperature that influences the drinking-water tap because of the water temperature in the container.
