Detailed description of the invention
To be the superiors be the formation of the freezing-cooling storeroom 1 shown in Fig. 1 has the refrigerating chamber 2 of double door 3L, 3R, lower one deck be have door 5 ice-making compartment 4 and have door 7 refrigerating chamber 6, again descend one deck be can pull out the refrigerating chamber 8 of mode, orlop is the vegetable compartment 9 that can pull out mode.The not shown cooling cycle system comprising compressor and heat exchanger is generation cold air, this cold air is assigned to each room by pipeline thus in each room, obtains required refrigerated storage temperature or the structure of cryogenic temperature.Described structure is well-known, does not therefore describe in detail.
The ice maker 10 shown in Fig. 2 and Fig. 3 is provided with at the top of ice-making compartment 4.Referring to Fig. 4 to Figure 10, its structure is described.
Fig. 2 is the profile of the ice maker 10 observed from the left direction of freezing-cooling storeroom 1.The wall of ice-making compartment 4 inboard is formed the pipeline 11 for cold air being blown into ice-making compartment 4.Ice-making disc shell 12 forwards stretches out from the upper end of pipeline 11.Becoming opening portion below ice-making disc shell 12, utilizing the ice of ice-making disc manufacture to fall for making.Pipeline 11 is formed with cold air discharge port 13 towards the inside of ice-making disc shell 12.
In the inside of ice-making disc shell 12, bearing the position of the cold air blown out from cold air discharge port 13, be configured with ice-making disc 20.Even if ice-making disc 20 molding synthetic resin also do not followed the string at low temperatures.In addition, if the bubble in the water provided is attached on the inner surface of ice-making disc 20, be then difficult to obtain transparency ice.So preferably implement using the moulding material of material as ice-making disc 20 allocating silicon in polypropylene into, or bubble is made to be difficult to be attached to the process in ice-making disc 20 by the ice-making disc 20 etc. after fluororesin coating molding.
Also generation transparency ice is hindered by the particulate of the electrostatic attraction produced on the surface of ice-making disc 20.Therefore preferably implement the material with being difficult to produce electrostatic, such as, make ice-making disc 20 shaping with the resin allocating silicon into or the resin that is mixed into antistatic agent, or ice-making disc 20 after shaping applies the countermeasures such as antistatic agent.
Ice-making disc 20 has eight ice making unit 21 altogether, and it is trapezoidal ice that described ice making unit 21 manufactures section.Eight ice making unit 21 line up 2 row 4 row, and therefore the flat shape of ice-making disc 20 is elongated shape.Ice-making disc 20 elongated like this configures in the mode that its long side direction is consistent with the depth direction of freezing-cooling storeroom 1.
One end of the long side direction of ice-making disc 20 is provided with bolster 22, the other end is provided with receptacle portion 23.Bolster 22 is rotatably bearing on ice-making disc shell 12.Receptacle portion 23 and be arranged on ice-making disc shell 12 inside stripping ice production apparatus 24(with reference to Fig. 3) axle be combined, be stripped ice production apparatus 24 and support.Bolster 22 and receptacle portion 23 are configured on common horizontal axis.Peel off ice production apparatus 24 and there is motor and deceleration device, ice-making disc 20 is rotated in the certain angle scope being turning cylinder with described horizontal axis.
Below ice-making disc 20, on the position between the ice making unit 21 lining up 2 row, be configured with thermistor 25.Thermistor 25 is through the temperature of wall measurement ice making unit 21 inside of ice making unit 21.
What fix thermistor 25 is thermistor cover 26.Pin 27 stretches out from four angles of thermistor cover 26 and the long side direction of ice-making disc 20 direction at a right angle.Amount to four legs 28 to stretch out below ice-making disc 20 in the mode of surrounding thermistor 25.The horizontal hole 29 that pin 27 is passed is formed in the front end of leg 28.By thermistor protective layer 30 overlapping on thermistor 25, thereon overlapping thermistor cover 26 and make pin 27 engage with the horizontal hole 29 of leg 28, fixing thermistor 25.
Below ice-making disc 20 except thermistor 25, be also configured with the heater 31 shown in Fig. 5.Heater 31 covers heater strip with silicones, and entirety can flexibly be reversed with ice-making disc 20.Each ice making unit 21, the apex portion spun upside down under state, be formed with the parallel ribs 32 that can fill heater 31.
Parallel ribs 32 is formed with the spaced and parallel configuration of regulation by two ribs, and the interval between rib is configured to fill heater 31 in the mode of loose fit.Interval between such setting rib is in order to when reversing ice-making disc 20, makes heater 31 can be movable to a certain extent.
Heater 31 is arranged to the symmetrical shape of the center line of the long side direction of ice-making disc 20.In the present embodiment, global shape is roughly U-shaped.A pair feeder line 33 is connected with at the position of the open end of U-shaped.
Heater 31 is little owing to designing caloric value, so be the structure superfine heater strip is wrapped on the core of glass fibre.If therefore to the direction twisting heater 31 taken up, then heater strip easily breaks.So as previously mentioned, make heater 31 can be to a certain degree freely movable, and the integral arrangement shape of heater 31 will be made to be try not to apply heater strip the shape of undue power.
Heater 31 is loaded in parallel ribs 32, is close to below ice-making disc 20, and cover below ice-making disc 20 with cover 34.Cover 34 prevents cold air from entering position below ice-making disc 20, makes the uniformity of temperature profile between each ice making unit 21.In addition, cover 34 and serve effect heater 31 got lodged in parallel ribs 32.
Cover 34 is rectangular plate-likes, is at one end formed with the ring 35 that bolster 22 is passed.Cover 34 is embedding ring 35 and bolster 22 under the state coordinated, and is arranged in ice-making disc 20 with two screws 36 and a spring 37.The installation of cover 34 is not the activity fettering ice-making disc 20 securely, but fetters ice-making disc 20 neatly in the mode not affecting the twisting ice-making disc 20 when peeling off ice.Cover 34 itself is also the same with ice-making disc 20, preferably by the molding synthetic resin also do not followed the string at low temperatures.
On cover 34, near the two ends of the center line of long side direction, be formed with two through holes 38.In addition, than the position of through hole 38 closer to cover central authorities, be formed with two through holes 39, the center line across long side direction is symmetrical.Through hole 38 is circular, makes the section formed below ice-making disc 20 be that circular projection 40 is passed.Through hole 39 is rectangles, and the mounting spring rib 41 formed below ice-making disc 20 is passed.
If screw 36 is screwed into the projection 40 exposed from through hole 38 fix, then covers 34 and come off with baffle plate for preventing with screw 36, be supported to move along the axis of protruding 40.Namely screw 36 is not fixed cover 34 tightly, but stops cover 34 to be separated with ice-making disc 20.
As shown in Figure 6, if cover 34 prevents from coming off with screw 36, then mounting spring rib 41 stretches out from the through hole 39 of cover 34.The installation hook 43 at spring 37 two ends engages with the horizontal hole 42 formed in the front end of mounting spring rib 41.Spring 37 installs hook 43 to have at long side direction central part, the form that has hairpin structure portion 44 at the two-end part of long side direction is bent to form by spring steel wire material.
Hairpin structure portion 44 extends to the oblique below in Fig. 6, and the direction in other words to ice-making disc 20 extends.As shown in Figure 7, the hairpin structure portion 44 of spring 37 is lower than installing hook 43, and the line part connected between hairpin structure portion 44 is divided into level.Therefore after making installation hook 43 engage with the horizontal hole 42 of mounting spring rib 41, hairpin structure portion 44 and the straight line portion compressing cover 34 connected between hairpin structure portion 44.As shown in Figure 3, cover 34 is pressed against on heater 31, with certain load supports heaters 31, described heater 31 is not come off from parallel ribs 32.Therefore, heater 31 is close on ice making unit 21, effectively the heat of heater 31 can be passed to ice making unit 21.
As shown in Figure 8, on cover 34, be formed with rib 34a, described rib 34a along the shape of heater 31 heater 31 by being pressed in ice-making disc 20.By the existence of rib 34a, the contact area of heater 31 and cover 34 is reduced, thus slip between the heater 31 certainly led to when ice-making disc 20 can be made to reverse and cover 34 is smooth.In addition, because the existence of rib 34a, the intensity of cover 34 is also improved.
The transverse ribs 34b connected between rib 34a is also formed on cover 34.The position consistency of cover 34 oppressed by the position of rib 34b and spring 37.Therefore the pressure uniform from spring 37 can be passed to heater 31.The existence of rib 34b is also of value to strengthening cover 34.
As shown in Figure 9 and Figure 10, heater 31 with the side faced by cover 34 on be formed with highly lower bar shaped projection 31a.Described bar shaped projection 31a serves the effect of differentiating heater 31 whether twisted configuration.
On two edges of the long side direction of ice-making disc 20, be provided with the wind shutter 45 to downward-extension one-body moldedly.Wind shutter 45 stops the cold air that blows to ice-making disc 20 from top around to below.Therefore can prevent because cold air enters into the heating effect impairing heater 31 below ice-making disc 20, cold air is concentrated on above ice-making disc 20.
On wind shutter 45, the position that the border between ice making unit 21 is consistent, is formed from edge to the recess 46 that vertical direction is cut.In the present embodiment, one piece of wind shutter 45 there are two recesses 46.If do not arrange recess 46, when twisting ice-making disc 20, the stress of wind shutter 45 is just concentrated in a position, and the resin material at this position albefaction will occur in early days, promotes to produce be full of cracks.By forming recess 46, make the stress dispersion of wind shutter 45, thus stop generation albefaction or be full of cracks.
As shown in Figure 3, between wind shutter 45 and cover 34, be provided with gap 47, even if twist wind shutter 45 described in ice-making disc 20 and described cover 34 also can not contact with each other to peel off ice.
The side of the side of one end of bolster 22 side of ice-making disc 20 is formed with projection 48.Projection 48 for producing moment of torsion when peeling off ice in ice-making disc 20.
Bearing what control the entirety of freezing-cooling storeroom 1 is the control part 50 shown in Figure 11, and described entirety controls the running comprised cooling cycle system and controls and control the energising of heater 31.Being connected to except on control part 50 except peeling off ice production apparatus 24 and heater 31, becoming the compressor 51 of a ring of cooling cycle system, being also connected on control part 50 to the pressure fan 52 of each several part transporting cold-air in storehouse, the water supply installation 53, temperature sensor 54 and the ice quantity sensor 55 etc. be configured in ice-making compartment 4 that supply water to ice maker 10.Temperature sensor 54 comprises the temperature elements such as the thermistor be configured in each several part, wherein also comprises thermistor 25.
Control part 50 makes following three phases the channel electric controlled to heater 31.Namely " generally heating ", caloric value ratio " generally heat " little " preheating ", caloric value ratio and " generally heat " large " Fast Heating ".The power consumption that such as can set " generally heating " is 5 ~ 6W, and the power consumption of " preheating " is 2W, and the power consumption of " Fast Heating " is 7 ~ 8W, makes caloric value variant.
The action of flow chart to ice maker 10 referring to Figure 12 is described.The state that flow process peels off ice action to complete, ice-making disc 20 turns back to upwards of Figure 12 starts.
In step #101, control part 50 makes water supply installation 53 action, supplies water to ice-making disc 20.
Because the temperature of ice-making compartment 4 is near cryogenic temperature (being set as-18 DEG C), so after supplying water, the temperature of ice-making disc 20 raises.In step #102, thermistor 25 detects the rising of described temperature.
Due to firm once cooling of supplying water, so the temperature that thermistor 25 is measured just starts after temporarily raising to reduce.Enter into step #103 thus.
Step #103 is icing preparation process.Control part 50 pairs of heaters 31 carry out the energising of " preheating ", make water temperature with the rate reduction of regulation.
Also heat with heater 31 in step after this.By freezing while heating ice-making disc 20 below with heater 31, transparency ice can be made not from the position contacted with ice-making disc 20 inner surface, and generating from leaving the position of ice-making disc 20 inner surface, therefore easily making the high ice of transparency.
In the midway of step #103, when compressor 51 entered between withholding period, temperature reduces nature and slows down.Control part 50 stops the energising to heater 31, thus avoids unnecessary power consumption.
In addition, control part 50, when the measuring tempeature of thermistor 25 is more than setting, such as, time more than 1 DEG C, stops being energized to heater 31.Be energized to produce from the position contacted with ice-making disc 20 to heater 31 and freeze, avoid unnecessary power consumption thus.
In step #104, control part 50 checks whether the temperature that thermistor 25 is measured is reduced to below freezing.If be reduced to below freezing, then enter into step #105.
Step #105 is ice melting step.Control part 50 pairs of heaters 31 only carry out the energising of " Fast Heating " of certain hour, heat ice-making disc 20.Even if because of the measure error of thermistor 25, transfer to step #105 evening from step #104, ice is attached on the inner surface of ice making unit 21 sometimes, and described ice will melt in this stage.Therefore can not produce the residual ice being an impediment to and obtaining homogeneous transparency ice, can step #106 be transferred to.
Control part 50 in step #105 not tube compressor 51 be on-stream or in stopping, all heater 31 being carried out to the energising of " Fast Heating ".Therefore can ice be melted quickly.
Step #106 is the step of carrying out freezing.The energising that control part 50 pairs of heaters 31 carry out " generally heating ", until the measuring tempeature of thermistor 25 is reduced to set point of temperature.
Control part 50 in the midway of step #106, when compressor 51 entered between withholding period, stop the energising to heater 31, avoids unnecessary power consumption.But because stopped the energising to heater 31, when compressor 51 restarting running, likely producing on the inner surface of ice-making disc 20 and freezing.So after compressor 51 restarts running, only carry out the energising of " Fast Heating " of certain hour to heater 31, if having icing in the inner surface generation of ice-making disc 20, it is just made to melt.Even if therefore intermittently carry out the energising to heater 31, also transparency ice can be generated continuously.
In step #107, control part 50 checks whether the temperature that thermistor 25 is measured is reduced to set point of temperature.If the temperature that thermistor 25 is measured is reduced to the set point of temperature of such as-9 DEG C, just judges to complete ice making, enter into step #108.
In step #108, control part 50 stops the energising to heater 31.After certain hour, judge really to generate transparency ice, just enter into step #109.
In step #109, control part 50 makes stripping ice production apparatus 24 carry out the rotary movement of ice-making disc 20.Peeling off ice production apparatus 24 makes ice-making disc 20 after bolster 22 rotates, and be near completion the stage before spinning upside down, projection 48 encounters the not shown baffle plate formed on ice-making disc shell 12.Also continue to make ice-making disc 20 rotate the angle of regulation, so ice-making disc 20 is out of shape by reversing owing to after this peeling off ice production apparatus 24.As previously mentioned, gap 47 is provided with between wind shutter 45 and cover 34, even if ice-making disc 20 is reversed, described wind shutter 45 and described cover 34 also can not contact with each other, the sound that sends creak creak or mutually wear and tear so the edge of cover 34 and wind shutter 45 can not rub mutually.
After twisting ice-making disc 20, the ice in ice making unit 21 is extruded, and falls in the not shown ice container be placed in ice-making compartment 4.After peeling off ice, peel off ice production apparatus 24 and ice-making disc 20 is rotated round about, make ice-making disc 20 turn back to original direction.Complete the ice-making activity of one-period thus.If ice quantity sensor 55 notifies that ice amount in ice container not enough, then continue the ice-making activity starting next cycle.If ice quantity sensor 55 notifies that the ice in ice container is enough, then ice maker 10 entered between stand-down.
Also ice maker 10 action as the flow chart of Figure 13 can be made.In the flow chart of Figure 13, the step except step #108 ' is all identical with the flow chart of Figure 12.In step #108 ', after the measuring tempeature of thermistor 25 is reduced to set point of temperature, control part 50 is not stop the energising to heater 31 at once, but the electrical current to heater 31 is reduced gradually, until stop energising.
The temperature not being each ice making unit 21 must be all consistent with the measuring tempeature of thermistor 25.Even if the measuring tempeature of thermistor 25 is reduced to set point of temperature sometimes, the temperature of the ice making unit 21 of a part is not also reduced to described set point of temperature, and remains the water do not frozen.Not be reduced to set point of temperature for opportunity with the measuring tempeature of thermistor 25, stop the energising to heater 31 quickly, but by reducing electrical current gradually until stop the process of energising, can remain with the state of not freezing by anti-sealing.
Control part 50 also carries out following action.
Ice-making compartment 4 indoor temperature or be blown into ice-making compartment 4 cold air temperature more than setting time, control part 50 makes the electrical current to heater 31 be low level.As an example, make the design temperature of acquiescence be-18 DEG C, if temperature is higher than-18 DEG C, then make the electrical current to heater 31 be low level.If temperature is less than-18 DEG C, then the electrical current to heater 31 is made to be general level.
By being energized to heater 31 by the required heat that carries out controlling to freeze like this, ice making operation optimization can be made.
Outside temperature low and temperature of refrigerating chamber sets higher time, control part 50 makes the rotating speed of the rotating speed of compressor 51 and pressure fan 52 reduce.
If outer temperature is low and temperature of refrigerating chamber sets higher, then the limited operational times of usual compressor 51, therefore cold air encounters the time shorten of ice-making disc 20, thus causes ice making time to extend.All can reduce by making the rotating speed of the rotating speed of compressor 51 and pressure fan 52, extending the duration of runs of compressor 51, thus shorten ice making time.
The invention is characterized in the structure of cold air discharge port 13.As shown in Figure 2, cold air discharge port 13 is divided into upper and lower two parts, points to the distant place flow export 13a of the distal portion of ice-making disc 20 when upper part is and sees from cold air discharge port 13.Point to when lower part is seen from cold air discharge port 13 near ice-making disc 20 and use flow export 13b near part.
Be set to than little from the air quantity of neighbouring flow export 13b outflow with the air quantity that flow export 13a flows out from afar.Such as can realize greatly than distant place flow export 13a with flow export 13b near making.
By arranging distant place flow export 13a and neighbouring flow export 13b like this, cold air is not concentrated on the specific ice making unit 21 of ice-making disc 20, and each ice making unit 21 can freeze equably.
In addition, if use flow export 13b near only having, then near only having the cold air discharge port of ice-making disc 20, position is cooled by brute force, and produces large temperature difference between distant sites.Owing to there being distant place flow export 13a, carry out supplementing cooling to distant sites as auxiliary cold air with the cold air of the little air quantity of flow export 13a outflow from afar.Its result, can suppress the temperature between ice making unit 21 uneven, owing to evenly freezing in each ice making unit 21, so can control icing rate simply with heater 31, thus improve the transparency of ice.
In the present embodiment, cold air discharge port 13 is divided into upper and lower two parts, but dividing number is not limited thereto, also can be more.In addition, cold air discharge port 13 can not be above-below direction segmentation, but left and right directions segmentation, such as using left-hand component as distant place flow export, using the structure of right-hand component as neighbouring flow export.
Above embodiments of the present invention are illustrated, but not delimit the scope of the invention, various change can also be implemented without departing from the spirit and scope of the present invention.
