Abstract
The utility model discloses a full-automatic clothes washing external barrel with a PTC heater installed, and relates to the field of household appliances. The full-automatic clothes washing external barrel with the PTC heater installed comprises an external barrel body and an internal barrel component, wherein the external barrel body is provided with a barrel cover, the internal barrel component is arranged inside the external barrel body and is connected with a shaft of the external barrel body, and a PTC heater is installed at the bottom of the external barrel body. Heating on water can be achieved when clothes washing is conducted, a cleanly-washing ratio is improved, and quick and hot drying of clothes is achieved through heating when dewatering and drying is conducted.
Description
Technical field
The utility model relates to field of household appliances, is specifically related to a kind of outer bucket of fully-automatic washing that PTC heater is housed.
Background technology
In washing machine when washing,, the too low activity of enzyme that will cause of water temperature is not strong, and decontamination stain indifferent when ℃ low temperature of water temperature＜15, carries out laundry operation after needing suitably heat to water again, specifically is that water is warmed to 30 ℃ at least.Generally speaking, water temperature is crossed when hanging down, just wash after needing suitably to improve water temperature, so that washing procedure in the time with greasiness removal, the outer bucket of existing laundry mode of heating generally selects for use the electrothermal wire heating to manage, surface temperature height during the heating wire energising, need dress temperature detect switch (TDS) or temperature sensor regulation and control hot-wire temperature, when temperature sensor or temperature detect switch (TDS) are malfunctioning, the phenomenon that anhydrous dry combustion method will occur, the temperature fuse that is equipped with in the heat-generating pipe will be caused open circuit by fuse, heat-generating pipe is scrapped, and has potential safety hazard.
And ptc heater refers to temperature automatically controlled PTC ceramic heater.Ptc heater tool constant temperature heat generation characteristic, its principle is: during the energising of PTC heater, because room temperature resistance is less, so initial current is bigger, can make the very fast heating up of PTC heater, cause resistance value own to increase sharply and enter the transition district, at this moment can be very little by the electric current of PTC heater, make PTC heater surface temperature remain steady state value.When the ptc heater of selecting low temperature for use, just can realize efficient, safe washing water temperature heating means, also can realize the air-dry clothing effect of dehydration fever simultaneously.
At present, ptc heater is contained on the outer bucket of automatic washing machine laundry and yet there are no application.
Summary of the invention
The utility model provides a kind of outer bucket of fully-automatic washing that PTC heater is housed in order to overcome the deficiency that prior art exists.
The utility model can be achieved by taking following technical scheme:
The outer bucket of a kind of fully-automatic washing that PTC heater is housed comprises the outer bucket that has bung, places in the outer bucket and the interior tub assembly that links to each other with outer bucket axle, and described outer barrel bottom is equipped with PTC heater.
Optionally, described PTC heater is annular.
Optionally, described PTC heater is parallel shape.
Optionally, described PTC heater is actiniform.
Optionally, described PTC heater body is flat-shaped bar shaped.
Optionally, described PTC heater body is the bar shaped of circle shape.
Preferably, described PTC heater is drawn two lead-out wires, outsourcing insulating materials.
Preferably, described PTC heater adopts the mode of many parallel operations.
Preferably, described PTC heater is furnished with temperature sensor.
Compared with prior art, the utility model adopts ptc heater.Ptc heater tool constant temperature heat generation characteristic, heating up is fast, and the back resistance that heats up increases sharply, and reduces size of current, and the oneself suppresses excessive temperature and rises, and makes PTC heater surface temperature remain steady state value.Adopt ptc heater as the heater of washing machine, can realize that efficient, safe washings heat, also can take into account the air-dry clothing effect of dehydration fever.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
The outer bucket of fully-automatic washing that a kind of shown in Fig. 1 ~ 6 is equipped with PTC heater comprises the outer bucket 2 that has bung 1, place in the outer bucket 2 and with 2 interior tub assemblies 3 that link to each other of outer bucket, outer bucket 2 bottoms are equipped with PTC heater 8, this outer bucket of fully-automatic washing that PTC heater is housed also includes clutch pack 4, valve body 5, seal cover board 6, sealing ring 7, PTC heater 8, temperature sensor 9 or temperature controller 9, the bottom of outer bucket 2 is provided with the groove position and places PTC heater 8.
Computer program controller is by lead link to each other with PTC heater 8, temperature sensor or temperature controller electricity respectively (as Fig. 2, shown in Figure 5), as select low temperature PTC heater 8 for use, not tight to temperature requirement, also can save temperature sensor and temperature controller (as Fig. 3, Fig. 4, shown in Figure 6).Fig. 4 makes large-area PTC heater 8 annulus modes, and this mode can have more heat-conducting area, favourable thermal output.Seal cover board 6 is be used to covering PTC heater 8 in the groove position of outer bucket 2, intercepting water in the mode of sealing ring 7 sealing flows in the groove and influences PTC heater work, seal cover board 6 can be that aluminium alloy also can be other heat conduction material preferably, be fixed on seal cover board 6 bottom surfaces behind the PTC heater 8 outsourcing insulating materials, heat is transmitted better like this.
When carrying out water temperature when heating, computer program controller is directly controlled PTC heater 8, for temperature is accurately controlled, thereby is provided with temperature sensor 9 or temperature controller 9.
For further improving convenience of the present utility model, the utility model also can be taken into account the laundry machine dehydration hot blast and do.In dehydration when air-dry, PTC heater 8 heating of switch on simultaneously, acceleration water evaporates.
Strengthen heat power as need, the power supply that also many PTC heaters 8 can be connected in parallel strengthens groove position and seal cover board 6 simultaneously.
The above person of thought, it only is the preferred embodiment of the utility model, when the scope that can not limit the utility model enforcement with this, namely the content of putting down in writing according to the utility model claim and utility model specification has generally been done the simple equivalent variation and has been modified, and all still belongs within the utility model claim institute covering scope.In addition, summary part and title only are the usefulness of auxiliary patent document search, are not the interest field that limits the utility model.
