Fig. 1 is a schematic structural diagram of a refrigerator according to a preferred embodiment of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a refrigerator 100 according to a preferred embodiment of the present invention includes a refrigerator body 1, a door body 2, and a plurality of compartments 3 defined by the refrigerator body 1 and the door body 2. One of the compartments 3 is a thermostatic chamber 32 for storing articles or food with high temperature requirements.
In a specific embodiment, the compartment 3 further includes a refrigerating compartment 31 and a freezing compartment 32, and the thermostatic chamber 32 is located in the refrigerating compartment 31 and is in a relatively stable refrigerating environment, so that temperature fluctuation in the thermostatic chamber 32 is relatively less affected by the ambient temperature.
Further, the refrigerator 100 further includes a cooling unit 4 for cooling the thermostatic chamber 32, at least one tray 5 located in the thermostatic chamber 32, a room temperature sensor 6 for detecting a temperature in the thermostatic chamber 32, a tray temperature sensor 7 for detecting a temperature of the tray 5, and a controller for controlling an operation of the refrigerator 100.
The tray temperature sensor 7 may be any one that can detect the temperature of the tray 4, and the installation position thereof is not limited. Preferably, the tray temperature sensor 7 is disposed on the tray 5 and is close to or located on the upper surface of the tray 5 to take account of the temperature of the tray 5 and the food on the tray 5.
After the food is placed on the tray 5, the food is in direct contact with the tray 5 to rapidly transfer heat, and the temperatures of the food and the tray 5 are rapidly consistent, so that the temperature of the tray 5 is close to the temperature of the food, and it can be understood that the tray temperature sensor 7 indirectly measures the temperature of the food by detecting the temperature of the tray 5.
The cooling unit 4, room temperature sensor 6, tray temperature sensor 7 all with the controller communication is connected, the controller opens and stops according to room temperature and tray temperature control cooling unit 4, has compromise the temperature of thermostatic chamber 32 with the food that is located it, makes temperature fluctuation is less in the thermostatic chamber 32.
The tray 5 at least comprises a first tray 51 and a second tray 52 which are arranged at intervals, and the tray temperature sensor 7 at least comprises a first tray temperature sensor 71 and a second tray temperature sensor 72 which are respectively used for detecting the temperatures of the first tray 51 and the second tray 52. A plurality of trays 5 are located in different positions in thermostatic chamber 32, and the temperature distribution at different positions in thermostatic chamber 32 can be known by measuring the temperature of each tray 5, thereby achieving a good effect of adjusting and maintaining the temperature constant.
In a specific embodiment, the second tray 52 is located on a side of the first tray 51 away from the door body 2, that is, the first tray 51 is close to the door body 2, and the second tray 52 is far away from the door body 2. Because the inevitable cold leakage phenomenon exists at the joint of the door body 2 and the box body 1, the temperature close to the door body 2 is usually slightly higher than the temperature inside; in the invention, the temperature of the starting point of the first tray temperature sensor 71 is higher than that of the second tray temperature sensor 72, and the temperature of the stopping point of the first tray temperature sensor 71 is higher than that of the second tray temperature sensor 72; therefore, frequent starting of the cooling unit 4 due to temperature fluctuation near the door body 2 can be avoided, and too low internal temperature can be avoided.
The cold supply unit 4 includes an air duct 41 communicated with the thermostatic chamber 32, at least one air inlet 42 for allowing the cold air in the air duct 41 to enter the thermostatic chamber 32, a cold source 43 located in the air duct 41, and a fan 44 for driving the cold air to enter the thermostatic chamber 32 from the air duct 41; the cold source 43 is an evaporator of a refrigerant refrigeration cycle unit, or the cold source 43 is a cold end of a semiconductor refrigeration unit, or the cold source 43 is a cold accumulation module. The constant temperature chamber 32 is cooled by cold air, so that the air in the whole compartment 3 has good fluidity and uniform temperature.
Further, the tray 5 is disposed at the bottom of the thermostatic chamber 32, the at least one air inlet 42 is disposed at the top of the thermostatic chamber 32, and the room temperature sensor 6 is also disposed at the top of the thermostatic chamber 32. On the one hand, the cold air sinks the hot air and rises, can be so that the temperature of whole thermostatic chamber 32 is comparatively even, on the other hand, room temperature sensor 6 is close to relatively thermostatic chamber 32's top, tray 5 reaches tray temperature sensor 7 is close to relatively thermostatic chamber 32's bottom can carry out effectual detection to the temperature of whole room 3.
In a preferred embodiment, the room temperature sensor 6 is located at the middle position of the top of the thermostatic chamber 32, and the at least one air inlet 42 is uniformly distributed around the room temperature sensor 6, so that the measurement of the room temperature is more accurate.
As shown in fig. 1, in a specific embodiment, the cooling unit 4 simultaneously supplies cooling to the freezing chamber 32, the air duct 41 includes a freezing air duct 411 for supplying cooling energy to the freezing chamber 32, a constant temperature air duct 412 communicated with the freezing air duct 411, and a damper 413 for communicating or cutting off the freezing air duct 411 and the air duct 41, and the fan 44 is disposed in the freezing air duct 411. As mentioned herein, starting the cooling unit 4 opens the damper 413, and if the fan 44 is not started, the fan 44 can be started at the same time; the air door 413 is closed when the cooling unit 4 is closed, and at this time, if the fan 44 is in an operating state due to the cooling demand of the freezing chamber 32, the fan 44 does not need to be closed.
The invention also provides a control method of the refrigerator, which comprises the following steps: acquiring the temperature of a compartment in the thermostatic chamber 32 and acquiring the temperature of the tray; when the compartment temperature reaches the starting point temperature of the room temperature sensor 6 and the tray temperature reaches the starting point temperature of the tray temperature sensor 7, the cooling unit 4 is started; the compartment temperature reaches the shutdown point temperature of the room temperature sensor 6, and when the tray temperature reaches the shutdown point temperature of the tray temperature sensor 7, the cooling unit 4 is turned off.
According to the control method of the refrigerator, the cold supply unit 4 is controlled to supply cold energy to the thermostatic chamber 32 according to the temperature of the chamber and the temperature of the tray, the temperature of the thermostatic chamber 32 and the temperature of food in the thermostatic chamber 32 are considered, and the temperature in the thermostatic chamber 32 is constant.
Before the cooling unit 4 is not started, only the compartment temperature reaches the start point temperature of the room temperature sensor 6, and when the tray temperature does not reach the start point temperature of the tray temperature sensor 7, the cooling unit 4 is started and stopped at a period of time t1 for start-up and t2 for stop, and the cooling unit 4 is stopped until the compartment temperature is lower than the start point temperature of the room temperature sensor 6.
Or, before the cooling unit 4 is not turned on, only when the tray temperature reaches the start point temperature of the tray temperature sensor 7 and the compartment temperature does not reach the start point temperature of the room temperature sensor 6, the cooling unit 4 is turned on and off at a period of time t1 when turned on and t2 when turned off, and the cooling unit 4 is turned off until the tray temperature is lower than the start point temperature of the tray temperature sensor 7.
In one embodiment, t1 is 80s and t2 is 170 s.
When one of the room temperature or the tray temperature reaches the corresponding starting point temperature, the cooling unit 4 is intermittently started to slowly supply cooling; on the one hand, the local overhigh temperature can be effectively avoided, and on the other hand, the phenomenon that the temperature at other positions is too low due to the fact that the cooling unit 4 is started because of the overhigh local temperature can be avoided.
The food is generally slower than the air temperature reduction speed in the thermostatic chamber 32, during the period of starting the cooling unit 4, after the compartment temperature is reduced to the shutdown point temperature of the compartment temperature sensor 6, the temperature in the food may not be reduced to the rational temperature, and the cooling unit 4 is started and stopped at the period of starting the cooling unit for t1 and shutting down the cooling unit for t 2; intermittent slow cooling is performed, and when the temperature of the food is slowly reduced to the temperature of the shutdown point, the cooling unit 4 is closed; compared with the direct closing of the cooling unit 4, the rapid temperature return of the compartment temperature can be avoided.
Specifically, the tray temperature sensor 7 includes a first tray 51 sensor that detects the first tray 51, and a second tray 52 sensor that detects the second tray 52. The plurality of trays 5 are positioned at different positions in the thermostatic chamber 32, so that the temperature of food at different positions can be detected, and a good effect of adjusting and maintaining the temperature constant is achieved.
When the first tray 51 and the second tray 52 are arranged side by side along the width direction of the door body 2 of the refrigerator 100, the distances between the two trays 5 and the door body 2 and the air inlet 42 are basically the same or similar, and the starting point temperature and the stopping point temperature of the first tray temperature sensor 71 and the second tray 52 sensor are the same.
When the second tray 52 is located on the side of the first tray 51 away from the door 2 of the refrigerator 100, the temperature of the starting point of the first tray temperature sensor 71 is higher than the temperature of the starting point of the second tray temperature sensor 72, the temperature of the shutdown point of the first tray temperature sensor 71 is higher than the temperature of the shutdown point of the second tray temperature sensor 72, the temperature distribution in the thermostatic chamber 32 is based on the temperature distribution, and the temperature is controlled by the cooling unit 4, so that the temperature is more uniform.
In addition, in consideration of the difference between the heat exchange rate of the food and the heat exchange rate of the air in the refrigerator 100, the control method of the refrigerator according to the present invention further adjusts the on/off temperature of each temperature sensor such as the room temperature sensor 6 and the tray temperature sensor 7 according to the load condition of the tray 5.
The control method of the refrigerator comprises the following steps: acquiring load information of a tray 5 in the refrigerator 100; acquiring the temperature of a compartment in the thermostatic chamber 32 and acquiring the temperature of the tray; and controlling the start and stop of the cooling unit 4 according to the start point temperature and the stop point temperature of the room temperature sensor 6 and the tray temperature sensor 7 under the current load condition.
The control method gives consideration to the compartment temperature, the food storage space and the food temperature, so that the temperature in the thermostatic chamber 32 is more uniform; the method can be used independently or based on the above-mentioned method for controlling the refrigerator 100.
According to the invention, the camera is arranged in the refrigerator for shooting or recording, the load condition of the tray is obtained through pictures or videos, or the scale is arranged on the tray or below the tray for weighing to obtain the load condition of the tray.
After the constant temperature function is started, when the tray 5 is unloaded, the cooling unit 4 is started, when the temperature of the compartment reaches the shutdown point temperature of the room temperature sensor 6 when the tray 5 is unloaded or the temperature of the tray reaches the shutdown point temperature of the tray temperature sensor 7 when the tray 5 is unloaded, the local temperature in the constant temperature chamber 32 reaches the set requirement, the cooling unit 4 is started and stopped at the cycle of starting up for t1 time and closing for t2 time, cooling is slowly supplied, and temperature rise in the constant temperature chamber 32 caused by sudden stop is avoided; when both the compartment temperature and the tray temperature drop to the shutdown point temperature, the cooling unit 4 is turned off.
In a preferred embodiment, when the first tray 51 and the second tray 52 located on the side of the first tray 51 away from the refrigerator door 2 are unloaded, the startup point temperature of the second tray temperature sensor 72 for detecting the second tray 52 < the startup point temperature of the room temperature sensor 6 < the startup point temperature of the first tray temperature sensor 71 for detecting the first tray 51, the shutdown point temperature of the room temperature sensor 6 < the shutdown point temperature of the second tray temperature sensor 72 for detecting the second tray 52 < the shutdown point temperature of the first tray temperature sensor 71 for detecting the first tray 51, and the second tray 52 is located on the side of the first tray 51 away from the refrigerator door 2 100.
After the cooling unit 4 is turned off, when the refrigerator 100 is in a normal on state, the control method of the refrigerator is adopted to control the on/off of the cooling unit 4, and only the temperature sensors are executed according to the temperature of the on/off point under the no-load condition.
Specifically, the control method of the refrigerator further includes: acquiring the temperature of a compartment in the thermostatic chamber 32 and acquiring the temperature of the tray; when the temperature of the compartment reaches the starting point temperature of the room temperature sensor 6 under the current load condition and the temperature of the tray reaches the starting point temperature of the tray temperature sensor 7 under the current load condition, the cooling unit 4 is started; and when the compartment temperature reaches the shutdown point temperature of the room temperature sensor 6 under the current load condition and the tray temperature reaches the shutdown point temperature of the tray temperature sensor 7 under the current load condition, closing the cooling unit 4.
Before the cooling unit 4 is not started, only when the compartment temperature reaches the starting point temperature of the room temperature sensor 6 under the current load condition, the cooling unit 4 is started and stopped at a period of starting time t1 and closing time t2, and the cooling unit 4 is closed after the compartment temperature is lower than the starting point temperature of the room temperature sensor 6 under the current load condition; or before the cooling unit 4 is not turned on, only when the tray temperature reaches the start-up point temperature of the tray temperature sensor 7 under the current load condition, the cooling unit 4 is turned on and off at the period of start-up time t1 and turn-off time t2, and the cooling unit 4 is turned off until the tray temperature is lower than the start-up point temperature of the tray temperature sensor 7 under the current load condition.
After the cooling unit 4 is started, when the room temperature drops to the shutdown point temperature of the room temperature sensor 6 under the current load condition, the cooling unit 4 is started and stopped at a period of time t1 when the cooling unit is started and t2 when the cooling unit is closed.
