A kind of anti-backwater structure of standing ironing machine
Technical field
The utility model is related to Garment Steamer Machine, more particularly to a kind of anti-backwater structure of standing ironing machine.
Background technology
At present, existing Garment Steamer Machine, if its steam nozzle is pressed excessively dead, or steam pipe is put too low, easily causes
Steam flows and ejection has some setbacks, and then steam is vexed in the cavity of steam pipe and heater, causes the steam of cavity to be filled
Pressure rise.Because the water in heater is connected with tank by water inlet pipe, in connection principle, under atmospheric pressure effect, hair
The water level balance in water level and tank in hot body, in the chamber pressure in heater is raised, this balance is just destroyed, mistake
Pressure high can be pushed back in screw clamp the water in heater by water inlet pipe, causes the cold water in tank to become hot water, is scorched
Water tank above tank and tank, and because the water in heater is pushed back, cause anhydrous in heater, formation dry combustion method, hair
Temperature control on hot body is jumped due to high temperature and broken.Steam cannot continue output.If cause repeatedly steam steam pipe place it is too low or
When spout is pressed too dead, steam can be produced intermittently.Even influence heater and temperature control life-span.

Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, Figure 2 and Figure 3, the anti-backwater structure of a kind of standing ironing machine, including host shell 1, in host shell 1
Water tank 2 and vapor cavity 3 are provided with, the bottom of water tank 2 is provided with tank 4, and tank 4 connects threeway seat 5, and the lower port of threeway seat 5 is provided with
Discharge outlet 6, discharge outlet 6 is provided with drain plug 7;The bottom of the vapor cavity 3 is connected with heater 8, and the bottom of heater 8 is provided with into water
Mouth 9, the side ports of the threeway seat 5 are connected to the water inlet 9 of the bottom of heater 8 by water inlet pipe 10;The bottom of the tank 4,
Threeway seat 5 side ports and upper port between, in the water inlet pipe 10 or bottom of heater 8 check-valves 11 is installed;The check-valves 11
Including sealing collar 11-1, sealing collar 11-1 is provided with collector nozzle 11-2, and sealing collar 11-1 bottom centre connects a guide pillar 11-3,
Sealing float 11-4, guide pillar 11-3 bottoms are cased with guide pillar 11-3 and are provided with spliced eye 11-5, and be plugged with banking pin 11-6.
When the check-valves 11 is arranged on 4 bottom of tank, the boss 4- for installing check-valves 11 is provided with the tank 4
1, the sealing collar 11-1 of check-valves 11 is provided with lock hole 11-7, is locked on boss 4-1 by screw.
Sealing silica gel ring 11-8 is provided between the sealing float 11-4 and sealing collar 11-1, strengthens sealing property.
The sealing float 11-4 is enclosed within the guide pillar 11-3 on sealing collar 11-1, in the presence of the buoyancy of water, makes to stop
Water float 11-4 floats along the guide pillar 11-3 of sealing collar 11-1, upper top sealing silica gel ring 11-8, seals sealing silica gel ring 11-8
The collector nozzle 11-2 of dead sealing collar, forms sealing.
Operation principle of the present utility model:
When in use, the water in water tank 2 is entered into heater 8 by tank 4 by threeway seat 5, water inlet pipe 10, is led to
The heating for crossing heater 8 makes water atomization, is sprayed from steam (vapor) outlet.When the steam pipe of connection vapor interface is put too low, or
When using, steam nozzle pressure clothing pressure must be excessively dead, causes steam to circulate and has some setbacks, due to hair in the vapor cavity 3 inside heater 8
Hot body 8 continues to produce steam, and air pressure inside becomes big so that the water in heater 8 passes through water inlet pipe 10 and threeway seat 5 toward tank 4
Interior backflow, and the hot water for flowing back is when sealing float 11-4 is met, sealing float 11-4 floats naturally, and seals silica gel ring 11-8
The collector nozzle 11-2 of sealing collar is sealed up jointly, sealing structure is formed, after sealing structure is formed, due to backwater inside heater 8
Path is shut, and will not also allow water to flow back in screw clamp 4 even if pressure is big again.
When the steam pipe for stretching steam (vapor) outlet, or shower nozzle do not paste dead clothing, when steam stream is clear and coherent smooth, steam natural
Can normally be sent out by steam pipe, reduce the pressure in vapor cavity 2 and heater.When pressure and atmospheric pressure keep balance
When, sealing float 11-4 due to the return pressure without hot water, in the presence of the inner cold water thrust of tank 4, just no longer with sealing
Circle forms sealing structure, and the water in tank 4 passes sequentially through sealing collar 11-1, threeway seat 5, water inlet pipe 10 and enters into heater 8, makes
The holding water level balance in water and heater 8 in tank 4.
