Description

With the water dispenser of PTC heating element heater

Technical field

The invention belongs to home appliance technical field, relate to a kind of water dispenser, particularly relate to a kind of water dispenser with PTC heating element heater.

Background technology

Current drinking machine apparatus adopts electrothermal tube and water channel to be set up in parallel substantially, structure is substantially install heating in the outside of water channel, and use heating to heat metal tube, the thermic load on heating surface is 10W ~ 15W/cm ², and thermal inertia is large, and start slow, heating soaks surface thermal load in water can not more than 0W/cm ².The thermal efficiency only has 57%, makes electric power large, poor stability, node weak effect.The current following problem of water dispenser ubiquity on the market: 1. start-up time is long, leaving water temperature is inadequate, and leaving water temperature only has 75 ~ 80 degree usually; 2. power consumption is large, does not meet national energy-saving environmental requirement; 3. the water of water dispenser is through constantly boiled and continuous insulation, drinks for a long time and is had a negative impact by human body.

Summary of the invention

The present invention is directed to the deficiency heating existence in above-mentioned electric heating drinking machine, propose a kind of water dispenser with PTC heating element heater, optimize the internal structure of water dispenser, be convenient to Design and manufacture, instant heating and use, leaving water temperature is high, energy-conserving and environment-protective, add the service life of water dispenser, use safer convenience.

Technical scheme of the present invention is: the water dispenser of band PTC heating element heater, comprise water dispenser case, inlet and outlet pipe lines and hot and cold water tap, it is characterized in that: the inside of described water dispenser case is provided with PTC heating element heater, described PTC heating element heater is made up of water inlet, delivery port, water back and heat generating component, described water back is by the brake forming of monoblock type aluminum pipe, described heat generating component is all arranged on the gap location of described water back, described water inlet is connected with inlet pipe of drinking water machine road with after described cold water faucet parallel connection, and described delivery port is connected with described hot water tap.

The cross section of described water back is the one in rectangle, square or circle.

The inwall of described water back is coated with insulating nano anti oxidation layer, and the material of insulating nano anti oxidation layer is one or more of nanometer strontium, Nano Silver, nanometer barium and nanostructured manganese.

Described heat generating component adopts ceramic semiconductors to make, and power attenuation is less than 5%.

The water pressure resistance of described water back at more than 10kg, when 1kg hydraulic pressure, heater water flow >=6L/min.

Beneficial effect of the present invention is: the water dispenser that the invention provides band PTC heating element heater, scientific structure, operation principle is clear, traditional heating component of drinking machine structure is improved.

1. the features such as this heating component adopts ceramic semiconductors ptc material to make heater, and the self-shield runback function utilizing PTC heating efficiency high, advanced, long service life, power attenuation are few, PTC heater does not contact with water, achieves electricity separation.

2. heater is when being energized, and PTC heater only generates heat, not luminous, paper also can not be made to blaze up, can not produce the danger such as electric shock, naked light even if be placed in dry paper; If the malfunctioning heater that causes of anhydrous or temperature controller is unloaded in pipeline; then heater arrives about 200 DEG C PTC resistances and sharply rises; now PTC has become insulator; thus cut off the electricity supply; PTC autoprotection gets up, and at this moment heater does not have electric current substantially, also just without power; even if long-time anhydrous dry combustion method, also can not burn out.Equitemperature reduce or pipeline water flowing time, PTC is recovery heating again, therefore anhydrous or unloaded time energising can the harm such as dry combustion method, not booster, leakproof, not initiation fire.

3. durable in use, the stable performance of PTC heater, is not easy aging, long service life.Use under home, PTC heater can use 8 ~ 10 years and not damage, and power attenuation also can not more than 5%.

4. non-scaling, adopt the heating of winding type overcurrent, loop is unimpeded.The contact surface temperature of duct wall and water only has about 200 DEG C, and water can not be very high by the temperature heated, and inner-walls of duct is smooth, smooth, is thus difficult in pipeline form incrustation scale.Incrustation scale is few, makes the thermal efficiency stable for extended periods of time of heating system, decreases the clean and maintenance cost in later stage simultaneously.

5. the thermal efficiency is high, and the exothermic material of ptc heater is wrapped in the middle of water pipe, and water pipe adopts whole aluminum pipe coiling to form, overlength water channel, PTC heater thermal conductive surface forms larger heat exchange area with the contact surface of water, and heating and heat conduction are extremely even, improve thermal conversion efficiency greatly.

6. anticorrosion is leaked, and pipeline adopts through the aluminum of surface oxidation treatment, and the surface that inner-walls of duct contacts with water, is coated with insulating nano anti oxidation layer, substantially increases the ability that pipeline hydraulic pressure resistance and anticorrosion are leaked.Water pressure resistance at more than 10kg, when 1kg hydraulic pressure, heater water flow >=6L/min.

7. lightly facilitate, this heater overall volume is small and exquisite, easy for installation.
