Abstract
The utility model relates to the improvement of a refrigerator, in particular to the improvement of a drainage device of a refrigerator evaporator. The drainage device comprises a water-holding groove and a drainage pipe, wherein the water-holding groove is arranged below the evaporator, and the drainage pipe is connected with the water-holding groove. The drainage device is characterized in that the water-holding groove and the drainage pipe are connected with each other through a metal connecting pipe provided with a first heater. As the metal connecting pipe is provided with the first heater, low temperature defrosting water from the water-holding groove is heated when passing through the metal connecting pipe, enters the drainage pipe and is then drained. Therefore, the ice clogging phenomenon of the drainage pipe can be effectively relieved and prevented.
Description
Technical field
The utility model relates to the improvement of refrigerator, specifically is the improvement of evaporator of refrigerator drainage arrangement.
Background technology
Because the evaporimeter of refrigerator can produce defrost water in the course of the work, in time draining this part defrost water, the bottom of conventional refrigerator evaporimeter is typically provided with water receiving tank, and this water receiving tank is connected with drainpipe.
The weak point of conventional refrigerator evaporimeter discharge structure is: because the temperature of the defrost water that evaporimeter produces itself is just lower, if refrigerator uses under low temperature environment, the stifled phenomenon of drainpipe ice then might take place in the drainpipe that then extends the refrigerator body, causes the refrigerator can't operate as normal.
The utility model content
The technical problem that the utility model solves provides a kind of drainage arrangement of evaporator of refrigerator, makes its drainpipe be not easy to ice the operate as normal of blocking up phenomenon and influencing refrigerator.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of drainage arrangement of evaporator of refrigerator comprises the water receiving tank and the drainpipe that is connected with this water receiving tank that are arranged on the evaporimeter below, it is characterized in that: connect by the metal connecting tube which is provided with primary heater between described water receiving tank and the described drainpipe.
As one of improvement of the present utility model: described primary heater also is connected with heating control apparatus.Heating control apparatus is used to control the work of the primary heater on the metal connecting tube and stops, thereby can improve the operating efficiency of heating controller, saves the energy.
As two of improvement of the present utility model: described heating control apparatus also is connected with secondary heater, and this secondary heater is arranged on the described evaporimeter.Because primary heater can not directly heat drainpipe, it is stifled to prevent that drainpipe from ice taking place, and blocks up and can not separate deicing.When having the ice slag in the drainpipe or ice taking place when stifled, the drainage arrangement of aforementioned schemes is with powerless.For the stifled phenomenon of the ice that further prevents drainpipe, keep drainpipe unobstructed, secondary heater can be set on evaporimeter.Secondary heater can melt the frost on the evaporimeter, through the heating of metal connecting tube, will be transformed into positive temperature defrost water after these defrost water are collected by water receiving tank, can change the ice slag in the drainpipe thus.And can also change frosting on the devaporation device in that second heater is set on the evaporimeter, improve the heat exchange efficiency of evaporimeter.
As three of improvement of the present utility model: described heating control apparatus comprises timing controller and is used to detect the temperature controller of evaporator temperature, this timing controller is connected with described secondary heater with described primary heater respectively, and this temperature controller is connected with this timing controller.Timer is used to control the work of primary heater and secondary heater or stop.
As four of improvement of the present utility model: described secondary heater is arranged on the bottom of evaporimeter, and described temperature controller is the temperature relay that is arranged on the evaporimeter.Evaporator of refrigerator bottom frosting generally is more serious, and it is better therefore secondary heater to be arranged on the base of evaporator effect.
As five of improvement of the present utility model: described metal connecting tube is an aluminium connecting tubes.
As six of improvement of the present utility model: described primary heater is the heating wire that is sleeved on the metal connecting tube.
As seven of improvement of the present utility model: described secondary heater is aluminum pipe heater or stainless steel heater.
Compared with prior art, the beneficial effects of the utility model are: because metal connecting tube is provided with primary heater, will be heated when the metal connecting tube from the low temperature defrost current of water receiving tank, and then intake-discharge pipe is discharged.Can effectively slow down and prevent the stifled phenomenon of ice of drainpipe thus.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
In the accompanying drawing, water receiving tank 1, aluminium connecting tubes 2, drainpipe 3, primary heater 4, secondary heater 5, temperature relay 6, evaporimeter 9.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the drainage arrangement of evaporator of refrigerator of the present utility model comprises: be arranged on evaporimeter 9 belows and the water receiving tank 1 that connects successively by stream, aluminium connecting tubes 2, drainpipe 3, and be arranged on the primary heater 4 on the aluminium connecting tubes 2 and be arranged on the secondary heater 5 of evaporimeter 9 bottoms, and the heating control apparatus that is connected with this primary heater 4, secondary heater 5 respectively.
This heating control apparatus comprises: timing controller (figure do not show) and be used to detect the temperature relay 6 of evaporimeter 9 temperature.Wherein this timing controller is connected with secondary heater 5 with primary heater 4 respectively, is used to control its work and stops.This temperature relay 6 then is connected with this timing controller, is used for the action of control timer.
Described primary heater is the heating wire that is sleeved on the metal connecting tube.Described secondary heater 5 is aluminum pipe heater or stainless steel heater.
Operation principle of the present utility model is: refrigerator running refrigerating, evaporimeter 9 frostings, the drainpipe 3 residual water slag that build-ups ice.Timing controller is accumulated meter to compressor operating time, and when compressor operating time is accumulated timing to design load (when evaporimeter 9 frostings are arrived to a certain degree), timing controller is connected primary heater 4 and secondary heater 5.Secondary heater 5 work heating make the frost on the evaporimeter 9 melt, and defrost water is collected by water receiving tank 1, and connects 21 to drainpipe 3 drainings via aluminium.Aluminium connects the primary heater 4 heater work heating on 21 simultaneously, the temperature of the feasible defrost water that flows through is increased to more than the positive temperature, and the defrost water of positive temperature melts drainpipe 3 residual ice slags and is washing away, and drainpipe 3 residual ice slags can not be accumulated and stops up drainpipe 3.When evaporimeter 9 temperature rise to design temperature, temperature relay 6 disconnects, and timing controller returns to initial position, carries out timing next time, and this moment, secondary heater 5 and primary heater 4 all quit work.
