Detailed description of the invention
Describe the present invention below with reference to each embodiment shown in the drawings.But these embodiments do not limit the present invention, the structure that those of ordinary skill in the art makes according to these embodiments or conversion functionally are all included in protection scope of the present invention.
Please refer to shown in Fig. 1, the present invention relates generally to a kind of refrigerator, described refrigerator include refrigerating chamber, refrigerating chamber, for refrigerating chamber and the refrigeration system of refrigerating chamber cooling and the temperature compensation system 10 for compensating temperature of refrigerating chamber.Described refrigerator has and forms the refrigeration inner bag (not shown) of described refrigerating chamber and the door body (not shown) of folding refrigerating chamber, and described refrigeration inner bag includes the postnotum (not shown) be oppositely arranged with described door body.
Described refrigerator is the mechanical refrigerator of single system.Described refrigeration system includes compressor 4 and evaporimeter (not shown), and described evaporimeter is arranged at the rear of postnotum.In the present embodiment, described evaporimeter is fixedly installed on the rear side of described postnotum, if refrigerator is wind cooling refrigerator certainly, evaporimeter is not fixed on postnotum, and directly cold wind is blown into refrigerating chamber by blower fan, also can reach object of the present invention.
Described temperature compensation system and described compressor 4 are arranged in series, and therefore described temperature compensation system can control unlatching or the shutdown of refrigeration system.Described temperature compensation system comprises the temperature compensation unit and temperature control unit that are arranged in parallel, and temperature control unit is in order to control the refrigeration work of compressor 4, and temperature compensation unit, in order to regulate temp. in refrigerating chamber, makes temperature of refrigerating chamber maintain more than 0 DEG C all the time.
Described temperature control unit comprises temperature controller 3 and second temperature sensitive switch 12 of series connection mutually.Described temperature controller 3 to be arranged in refrigerating chamber and to be provided with to measure the temperature-sensitive head of evaporator temperature, user can use temperature controller 3 pairs of refrigerators to regulate in advance according to environment temperature, compressor 4 is made to maintain normal startup, keep freezing indoor temperature below-18 DEG C, the freezen protective of food in refrigerating chamber can not be had influence on.
Described second temperature sensitive switch 12 senses refrigerating chamber or the temperature near refrigerating chamber place, in the present embodiment, second temperature sensitive switch 12 senses the temperature of refrigerating chamber postnotum, and described second temperature sensitive switch 12 is arranged on refrigerating chamber postnotum, and arranges away from evaporimeter.Because evaporimeter is arranged on refrigerating chamber postnotum, therefore the temperature of postnotum is lower compared to the temperature of refrigerating chamber, and has certain temperature difference, and the temperature of refrigerating chamber postnotum is more easily measured compared to the room temperature in refrigerating chamber.Described second temperature sensitive switch 12 is closed when the temperature detected arrives T3, disconnect when arriving T4.In the present embodiment, described T3 is-3 DEG C, and T4 is-10 DEG C.When the temperature that the second temperature sensitive switch 12 senses postnotum reaches-10 DEG C, the temperature of refrigerating chamber is also lower than 0 DEG C.Therefore, at this moment just need compressor 4 to be stopped refrigeration.But after compressor 4 stops refrigeration, if waiting temperature gos up naturally, then the time needed is oversize, and the food in refrigerating chamber may thaw, and will have influence on the preservation of food in refrigerating chamber like this.Therefore, just need temperature compensation unit, by temp. in refrigerating chamber fast lifting.
Described temperature compensation unit comprises the first temperature sensitive switch 11, heater 2 and the 3rd temperature sensitive switch 13.After described first temperature sensitive switch 11 and the 3rd temperature sensitive switch 13 parallel connection, then be in series with heater 2.The temperature-sensitive head of described temperature controller 3 is arranged near heater 2.Described 3rd temperature sensitive switch 13 measures ambient temperature, and closed when measuring tempeature arrives T5, disconnect when arriving T6.In the present embodiment, T5 is 13 DEG C, and T6 is 19 DEG C.When environment temperature is lower than 13 DEG C, the 3rd temperature sensitive switch 13 closes, then form path.If now temperature controller 3 is in closure state, then heater 2 is shorted, if now temperature controller 3 is in off-state, then heater 2 works, and the temperature that the temperature-sensitive head of temperature controller 3 senses rises, and temperature controller 3 closes, heater 2 is shorted, and compressor 4 starts refrigeration work.In addition, when the 3rd temperature sensitive switch 13 closes, because heater 2 resistance is quite large, the electric current therefore in path is very little, although thus heater 2 and compressor 4 connect, compressor 4 also can not start.3rd temperature sensitive switch 13 just prevents when temperature is too low, the situation that compressor can not start.
Described first temperature sensitive switch 11 senses refrigerating chamber or the temperature near refrigerating chamber place, in the present embodiment, described first temperature sensitive switch 11 is arranged on refrigerating chamber postnotum and also arranges near heater 2, arrange because heater 2 to be usually arranged on refrigerating chamber postnotum and to press close to evaporimeter, therefore the first temperature sensitive switch 11 compared to the second temperature sensitive switch 12 also closer to evaporimeter.Described first temperature sensitive switch 11 is closed when the temperature detected reaches T1, disconnect when arriving T2, in the present embodiment, because the first temperature sensitive switch 11 is relative to closer to evaporimeter, therefore the temperature at the first temperature sensitive switch 11 place is lower relative to the temperature at the second temperature sensitive switch 12 place, and has the temperature difference of more than 10 DEG C or 10 DEG C.So when the second temperature sensitive switch 12 senses temperature for-10 DEG C, the temperature at the first temperature sensitive switch 11 position place is slightly less than-20 DEG C, so in the present invention, T1 is set to-20 DEG C.Therefore, when temperature at the second temperature sensitive switch 12 place is slightly larger than-10 DEG C, second temperature sensitive switch 12 is in closure state, but the temperature at the first temperature sensitive switch place arrives-20 DEG C, and therefore the first temperature sensitive switch 11 closes, form path, but due to the second temperature sensitive switch closed in, and by heater short circuit, compressor continues refrigeration, until the temperature that the second temperature sensitive switch 12 senses reaches-10 DEG C, the second temperature sensitive switch 12 disconnects.
After second temperature sensitive switch 12 disconnects, heater 2 is started working, and because heater 2 resistance is quite large, therefore when heater 2 works, the electric current in path is quite little, although therefore heater 2 and compressor 4 are in series, compressor 4 also can not start.Heater 2 constantly heats, the temperature of refrigerating chamber is made to return to 0 DEG C fast, and, now because the first temperature sensitive switch 11 is near heater 2, therefore the temperature that senses of the first temperature sensitive switch 11 is much larger than 0 DEG C, in the present embodiment, T2 is 5 DEG C, namely when the temperature sensed when the first temperature sensitive switch 11 is 5 DEG C, the temperature in refrigerating chamber is greater than 0 DEG C, and the first temperature sensitive switch 11 disconnects.Now, second temperature sensitive switch 12 is also in off-state, but, because the second temperature sensitive switch 12 is far away apart from evaporimeter, therefore temperature increase is slower, in the present embodiment, the waste heat supply temperature of heater 2 is relied on slightly to promote, when the temperature at described second temperature sensitive switch 12 place reaches-3 DEG C, second temperature sensitive switch 12 closes, compressor 4 is started working, and refrigeration system starts refrigeration, then the temperature of refrigerating chamber is maintained more than 0 DEG C all the time.In the present embodiment, the first temperature sensitive switch 11, second temperature sensitive switch 12, the 3rd temperature sensitive switch 13 are magnet-sensitive switch, and heater 2 is heater strip or heating plate, and overlapping with described evaporator section.
Certainly, in present embodiment, closed and the break-off signal of the first temperature sensitive switch 11 and the second temperature sensitive switch 12 is determined by the particular location of the first temperature sensitive switch 11, second temperature sensitive switch 12, heater 2 and evaporimeter, if the first temperature sensitive switch 11, second temperature sensitive switch 12 is arranged at other places of refrigerating chamber, then corresponding T1, T2, T3, T4 can change.But, because the first temperature sensitive switch 11 is arranged near evaporimeter and heater, second temperature sensitive switch 12 is arranged away from evaporimeter, therefore in process of refrigerastion, the temperature of the first temperature sensitive switch sensing is all the time far below the temperature of the second temperature sensitive switch sensing, in heating process, the temperature of the first temperature sensitive switch sensing is also higher than the temperature of the second temperature sensitive switch sensing.
To sum up, when refrigerator work, first user regulates temperature controller 3, guarantees can work in compressor 4 at all seasons.Secondly, when outdoor temperature is lower than 13 DEG C, the 3rd temperature sensitive switch 13 closes, and circuit forms path.If now temperature controller 3 is in closure state, then heater 2 is shorted, if now temperature controller 3 is in off-state, then heater 2 is started working, then the temperature that the temperature-sensitive head of temperature controller 3 records raises, and temperature controller 3 is just closed, heater 2 is shorted, compressor 4 just starts refrigeration, and during to prevent environment temperature too low, compressor stops refrigeration, guarantees that the food in refrigerating chamber is not affected.
In addition, if compressor 4 continues refrigeration, the room temperature in refrigerating chamber may lower than 0 DEG C, and this will have influence on the fresh-keeping quality of food in refrigerating chamber.Further, evaporimeter is arranged at refrigerating chamber postnotum rear, and the temperature of refrigerating chamber postnotum is some more low compared to the room temperature of refrigerating chamber.Therefore in the ordinary course of things, when the refrigerating chamber postnotum temperature that the second temperature sensitive switch senses is lower than-10 DEG C, temperature in refrigerating chamber is just lower than 0 DEG C, now no matter temperature controller 3 is in state that is closed or that disconnect, second temperature sensitive switch 12 all disconnects, compressor 4 is not worked, prevents refrigerating chamber excessively cold.Then, temperature compensation unit heats up in refrigerating chamber.
Therefore, in the present embodiment, when the temperature that the second temperature sensitive switch 12 senses is-10 DEG C, because the first temperature sensitive switch 11 is arranged near evaporimeter and heater 2, second temperature sensitive switch 12 is away from evaporimeter, therefore the temperature that senses of the first temperature sensitive switch 11 is lower, so the closed temperature of the first temperature sensitive switch 11 is set to-20 DEG C.Therefore, after the second temperature sensitive switch 12 disconnects, the first temperature sensitive switch 11 closes, and heater 2 works.Because the first temperature sensitive switch 11 is arranged near heater 2, therefore when more than the first temperature sensitive switch 11 records temperature to 5 DEG C, the temperature in refrigerating chamber has been promoted to more than 0 DEG C.Now, the first temperature sensitive switch 11 disconnects.Temperature in refrigerating chamber relies on the waste heat of heater 2 slightly to go up.Due to the second temperature sensitive switch 12 apart from evaporimeter and heater 2 all far away, therefore the temperature recovery at the second temperature sensitive switch 12 sensing place is comparatively slow, when the second temperature sensitive switch 12 sense temperature for-3 DEG C time, temperature in refrigerator space is greater than 0 DEG C completely, now the second temperature sensitive switch 12 closes, and compressor 4 restarts refrigeration work.Thus, the temperature in refrigerating chamber can be maintained more than 0 DEG C all the time.
Heater 2, the 3rd temperature sensitive switch 13, temperature controller 3 are parts contained in conventional mechanical refrigerator, therefore the present invention adds the first temperature sensitive switch 11 and the second temperature sensitive switch 12 on conventional mechanical refrigerator, structure is simple, and temperature of refrigerating chamber can be prevented excessively cold, and temperature is maintained more than 0 DEG C all the time.
Be to be understood that, although this description is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of description is only for clarity sake, those skilled in the art should by description integrally, technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
A series of detailed description listed is above only illustrating for feasibility embodiment of the present invention; they are also not used to limit the scope of the invention, all do not depart from the skill of the present invention equivalent implementations done of spirit or change all should be included within protection scope of the present invention.
