Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
As shown in fig. 1, a schematic structural diagram of a single-system refrigerator is provided, which includes a main control panel 1, a fan 2, a refrigerating chamber air door 3, a variable temperature chamber air door 4, a refrigerating chamber air duct 5, a variable temperature chamber air duct 6, a freezing chamber air duct 7, an evaporator 8, a freezing chamber (not shown), a refrigerating chamber (not shown), a variable temperature chamber (not shown), and three temperature sensors (not shown) respectively disposed in the freezing chamber, the refrigerating chamber, and the variable temperature chamber. Wherein, the fan 2 is used for providing power to send the refrigerating capacity of the freezing chamber to the refrigerating chamber and the temperature changing chamber. And the refrigerating chamber air door 3, the temperature-variable chamber air door 4, the refrigerating chamber air duct 5, the temperature-variable chamber air duct 6 and the freezing chamber air duct 7 are used for providing a transmission channel of refrigerating capacity. The main control board 1 is connected with three temperature sensors arranged in the freezing chamber, the refrigerating chamber and the temperature-changing chamber, and is used for acquiring the temperature acquired by the temperature sensors, and further realizing the control method of the single-system refrigerator according to the temperature acquired by the temperature sensors.
In one embodiment, as shown in fig. 2, a method for controlling a single-system refrigerator is provided, which is described by taking an example that the method is applied to a main control board 1 of the single-system refrigerator in fig. 1, and includes the following steps:
in step S202, a first temperature of the freezing compartment and a second temperature of the non-freezing compartment are acquired.
The non-freezing chamber includes a refrigerating chamber and/or a temperature-changing chamber, for example, when the refrigerator is a double-door refrigerator, the non-freezing chamber includes only any one of the refrigerating chamber and the temperature-changing chamber. When the refrigerator is a three-door refrigerator, the non-freezing chamber includes two chambers, namely a refrigerating chamber and a temperature-changing chamber.
Specifically, temperature sensors for collecting the temperature of the current compartment are provided in the freezing compartment and the non-freezing compartment of the refrigerator, respectively. That is, the temperature sensor is placed inside the compartment and can be mounted at a fixed position. Then, the main control board obtains the first temperature of the freezing chamber and the second temperature of the non-freezing chamber collected by the temperature sensor in real time.
Step S204, a freezing chamber starting marker bit is determined according to the first temperature, and a non-freezing chamber starting marker bit is determined according to the second temperature.
The start flag is used to indicate whether the compartment needs to be started for cooling, for example, a logic 1 may be configured to indicate that cooling is needed, and a logic 0 indicates that cooling is not needed.
In particular, the temperature of the compartment can be visualized as to whether refrigeration is required. Therefore, the freezing chamber start flag is determined according to the first temperature of the freezing chamber and the non-freezing chamber start flag is determined according to the second temperature of the non-freezing chamber respectively. For example, when the first temperature of the freezing compartment is a temperature requiring cooling, the freezing compartment start flag is set to 1, and when the first temperature of the freezing compartment indicates that cooling of the current freezing compartment is not required, the freezing compartment start flag is set to 0. The determination of whether refrigeration is required may be made by comparing the temperature of the compartment to a temperature threshold at which refrigeration is required. For example, if the temperature of the freezing chamber is higher than a degrees celsius, which indicates that the freezing chamber needs to be cooled, the freezing chamber start flag is set to 1 when the first temperature is higher than a degrees celsius.
It should be understood that the actual use of the refrigerator is different in the degree of refrigeration for the freezing compartment and the non-freezing compartment, and therefore the temperature thresholds for the freezing compartment and the non-freezing compartment should be different. The first temperature of the freezing compartment is compared with a temperature threshold corresponding to the freezing compartment, and the second temperature of the non-freezing compartment is compared with a temperature threshold corresponding to the non-freezing compartment.
And step S206, controlling the working state of the compressor according to the freezing chamber starting marker bit and the non-freezing chamber starting marker bit.
Specifically, after the freezing chamber starting marker bit and the non-freezing chamber starting marker bit are determined, the main control board controls the working state of the compressor according to the freezing chamber starting marker bit and the non-freezing chamber starting marker bit, namely, the compressor is controlled to be started and stopped according to the freezing chamber starting marker bit and the non-freezing chamber starting marker bit.
When the freezing chamber flag bit indicates that the freezing chamber reaches a refrigerating point and needs to be refrigerated, the main control panel controls the compressor to start up for refrigeration. Or when the non-freezing chamber flag bit indicates that the non-freezing chamber reaches a refrigerating point and needs to be refrigerated, the main control panel controls the compressor to start to refrigerate. For example, when the freezing chamber flag or the non-freezing chamber flag is 1, the compressor is controlled to be turned on. The refrigerating capacity of the non-freezing chamber generally flows from the freezing chamber to the non-freezing chamber, so that when the non-freezing chamber needs to be refrigerated, the fan needs to be started and the air door corresponding to the non-freezing chamber needs to be opened besides controlling the starting of the compressor, so that the refrigerating capacity flows from the freezing chamber to the non-freezing chamber to achieve the purpose of refrigerating and cooling the non-freezing chamber. For example, when the refrigerating chamber in the non-freezing chamber needs to be refrigerated, the refrigerating chamber damper corresponding to the refrigerating chamber is opened. And if the temperature-variable chamber in the non-freezing chamber needs to be refrigerated, opening a temperature-variable chamber air door corresponding to the temperature-variable chamber.
The single-system refrigerator method obtains a first temperature of the freezing chamber and a second temperature of the non-freezing chamber; determining a starting marker bit of a freezing chamber according to the first temperature, and determining a starting marker bit of a non-freezing chamber according to the second temperature; and controlling the working state of the compressor according to the freezing chamber starting marker bit and the non-freezing chamber starting marker bit. The method controls the start and stop of the compressor in a mode of combining the temperature of the freezing chamber and the temperature of the non-freezing chamber, simultaneously considers the refrigeration requirement of the non-freezing chamber in the control process, and avoids the temperature of the non-freezing chamber from being higher, so that the accuracy of the control of the refrigerator is improved.
In one embodiment, step S206 includes: when the refrigerating chamber starting marker indicates that the refrigerating chamber reaches a refrigerating point, the compressor is controlled to start, and the fan and the air door corresponding to the non-refrigerating chamber are controlled to be opened and closed according to the non-refrigerating chamber starting marker; and when the freezing chamber starting marker indicates that the freezing chamber does not reach the refrigerating point, controlling the working state of the compressor according to the non-freezing chamber starting marker.
The reaching of the refrigerating point refers to that the first temperature of the freezing chamber or the second temperature of the non-freezing chamber reaches the temperature needing to be refrigerated, so whether the refrigerating point is reached can be determined according to whether the starting flag bit indicates that the refrigerator is started or not. For example, a power-on flag of flag 1 indicates that the cooling point is reached. And a 0 on flag indicates that the cooling point is not reached.
Specifically, when the freezing chamber starting flag bit indicates that the freezing chamber reaches a refrigerating point, in order to ensure the normal refrigerating function of the freezing chamber, the main control board immediately controls the compressor to start refrigerating to cool the freezing chamber. At this time, since the compressor is already started, whether the non-freezing chamber enters the refrigeration or not can be realized by controlling the fan and the corresponding damper of the non-freezing chamber. Therefore, when the compressor is controlled to start up due to the refrigeration requirement of the freezing chamber, the working states of the fan and the corresponding air door of the non-freezing chamber are further controlled according to the starting marker of the non-freezing chamber.
When the freezing chamber starting marker bit indicates that the freezing chamber does not reach the refrigerating point, the starting state of the compressor is controlled according to the non-freezing chamber starting marker bit in order to ensure the refrigerating requirement of the non-freezing chamber. When the freezing chamber does not need to be refrigerated, the main control panel controls the start and stop of the compressor according to the refrigeration requirement of the non-freezing chamber. When the non-freezing chamber flag bit indicates that the non-freezing chamber reaches the refrigerating point, the main control board controls the compressor to be started, and simultaneously controls the fan to be started, and controls the air door corresponding to the air-cooling freezing chamber to be opened, so that the refrigerating capacity flows from the freezing chamber to the non-freezing chamber to meet the refrigerating requirement of the non-freezing chamber.
In this embodiment, when the freezing chamber does not reach the refrigeration point and does not have the refrigeration demand, and then according to the start-up marker bit control compressor of the non-freezing chamber of non-freezing chamber, thereby satisfy the refrigeration demand of non-freezing chamber, avoid the temperature of non-freezing chamber to be on the high side, improved the accuracy nature of refrigerator control.
In one embodiment, controlling the operating state of the compressor according to the non-freezing-chamber starting flag bit comprises: when the non-freezing chamber starting marker indicates that the non-freezing chamber reaches a refrigerating point, maintaining the shutdown state of the compressor until the second temperature is raised to the preset starting temperature, controlling the compressor to start, controlling the fan to open and controlling the air door corresponding to the non-freezing chamber to open; and when the non-freezing chamber starting flag bit indicates that the non-freezing chamber does not reach the refrigerating point, controlling the compressor to stop.
The starting temperature is a preset temperature value for determining starting of the compressor, and the starting temperature in this embodiment is set for the non-freezing chamber, and is preferably higher than 2 degrees celsius of the temperature reaching the refrigeration point. For example, when the second temperature of the non-freezing compartment reaches T, which indicates that the non-freezing compartment reaches the refrigerating point, the start-up temperature is reached when the second temperature reaches T +2 degrees celsius, that is, the start-up temperature is set to T +2 degrees celsius.
Specifically, when the freezing chamber does not need to be refrigerated, the main control board controls the start and stop of the compressor according to the refrigeration requirement of the non-freezing chamber, and if the non-freezing chamber start flag of the non-freezing chamber indicates that the non-freezing chamber reaches a refrigeration point, namely when the second temperature of the non-freezing chamber reaches T, the main control board maintains the current stop state of the compressor and enters a waiting state. And the main control board continuously monitors the second temperature of the non-freezing chamber in a waiting state until the second temperature of the non-freezing chamber reaches the starting temperature, namely the second temperature of the non-freezing chamber reaches T +2 ℃, and then the compressor is controlled to start to refrigerate. Meanwhile, as the non-freezing chamber has a refrigeration requirement at the moment, the fan needs to be controlled to be opened at the same time, and the air door corresponding to the non-freezing chamber is controlled to be opened, so that the refrigeration capacity flows to the non-freezing chamber to achieve the purpose of refrigerating the non-freezing chamber. And if the non-freezing chamber starting flag bit of the non-freezing chamber indicates that the non-freezing chamber does not reach the refrigerating point, namely the current freezing chamber and the non-freezing chamber have no refrigerating requirement, the main control panel controls the compressor to stop.
It should be understood that when it is determined that the compressor needs to be controlled to start, if the compressor is in the start state at this time, the current start state can be regarded as being maintained without performing an additional control action. Similarly, when it is determined that the compressor needs to be controlled to stop, if the compressor is in a stop state, the current stop state is considered to be maintained without performing additional control actions.
In this embodiment, the temperature of the non-freezing chamber generally rises faster due to frequent use of the non-freezing chamber. Therefore, when the start and stop of the compressor are controlled by the non-freezing chamber, the start temperature higher than the refrigerating point temperature is additionally set to buffer and determine the start time point of the compressor, so that the frequent start and stop of the compressor caused by the control of the compressor by the temperature of the non-freezing chamber can be avoided, the energy consumption is reduced by reducing the start rate, and the service life of the compressor is prolonged.
In one embodiment, controlling the opening and closing of the fan and the corresponding damper of the non-freezing chamber according to the starting flag of the non-freezing chamber comprises: when the non-freezing chamber starting marker indicates that the non-freezing chamber reaches a refrigerating point, controlling a fan to be opened and controlling an air door corresponding to the non-freezing chamber to be opened, and generating power by the fan to enable refrigerating capacity of the freezing chamber to flow to the non-freezing chamber through an air duct; and when the non-freezing chamber starting flag bit indicates that the non-freezing chamber does not reach the refrigerating point, controlling the fan to be closed and controlling the air door corresponding to the non-freezing chamber to be closed.
Specifically, when the compressor is controlled to start up because the freezing chamber needs to be refrigerated, the main control panel further controls the state of the fan and the corresponding damper according to the refrigeration requirement of the non-freezing chamber. If the non-freezing chamber starting marker indicates that the non-freezing chamber reaches a refrigerating point, namely, for example, the second temperature of the non-freezing chamber reaches T, and the non-freezing chamber starting marker is 1, the non-freezing chamber needs to be refrigerated at the moment, so that the fan is controlled to be started, the air door corresponding to the non-freezing chamber is controlled to be opened, and the refrigerating capacity of the freezing chamber flows to the non-freezing chamber through the air duct and the air door by the power generated by the fan, so that the aim of refrigerating the non-freezing chamber is fulfilled. If the non-freezing chamber starting flag bit indicates that the non-freezing chamber does not reach the refrigeration point, that is, for example, the second temperature of the non-freezing chamber does not reach T, so that when the non-freezing chamber starting flag bit is 0, it indicates that the non-freezing chamber does not need to be refrigerated at this time, and therefore the fan can be controlled to be closed and the corresponding air door can be controlled to be closed.
In this embodiment, after the compressor is controlled to start according to the temperature of the freezing chamber, whether to open the fan and the air door is determined additionally according to the demand of the non-freezing chamber, so that a certain refrigerating capacity can be reduced, and the energy consumption is reduced.
In one embodiment, as shown in fig. 3, another method for controlling a single-system refrigerator is provided, which further includes the following steps before the compressor is controlled to start:
step S302, obtaining a starting-up time interval; the starting time interval is the time interval between the last starting time of the compressor and the current time.
Step S304, comparing the power-on time interval with a preset time interval threshold, and if the power-on time interval is greater than or equal to the time interval threshold, entering step S306. If the boot time interval is smaller than the time interval threshold, the process proceeds to step S308.
Step S306, controlling the compressor to start.
Step S308, the compressor is controlled to be started when the starting time interval is delayed to be larger than or equal to the time interval threshold value.
Wherein the time interval threshold is a minimum startup time interval that the configured compressor needs to meet.
Specifically, no matter whether the compressor is controlled to start up because the temperature of the freezing chamber needs to be refrigerated or the compressor is controlled to start up because the temperature of the non-freezing chamber needs to be refrigerated, the starting-up time interval is acquired to judge the minimum starting-up time interval as long as the compressor needs to be controlled to start up. The startup time interval may be calculated by obtaining a difference between the time recorded at the last startup of the compressor and the current time. And after the starting time interval is obtained, comparing the starting time interval with a preset time interval threshold, and determining whether the minimum starting time interval is met by currently controlling the compressor to start or not through comparison. When the starting time interval is greater than or equal to the time interval threshold value, the minimum starting time interval is met currently, and the main control board can directly control the compressor to start. And when the starting time interval is smaller than the time interval threshold value, the minimum starting time interval is not met currently, and the standby state is entered. And timing or monitoring time while waiting until the starting time interval is greater than or equal to the time interval threshold value, and then controlling the compressor to start.
In the embodiment, because frequent braking of the compressor easily causes abnormal conditions such as trip of the compressor, when the compressor is determined to be controlled to start, the compressor is controlled to start again when the starting time interval meets the minimum starting time interval, so that the abnormal conditions such as trip can be avoided, and the normal operation of the compressor is ensured.
In one embodiment, a control method of a single system refrigerator is explained in detail by taking an example in which a non-freezing compartment includes a refrigerating compartment and a temperature-changing compartment.
Specifically, referring to table 1 below, 0 indicates no cooling request and 1 indicates cooling request.
TABLE 1
When the starting flag of the freezing chamber is 1, the compressor is inevitably controlled to start. And when the starting marker bit of the freezing chamber is 0, the working state of the compressor is determined according to the starting marker bits of the refrigerating chamber and the temperature-changing chamber. That is, when the start flag bits of the refrigerating chamber and the temperature change chamber are both 0, the refrigerating chamber and the temperature change chamber are both free of refrigeration requirements, and the compressor is controlled to stop. When the starting flag bit of the refrigerating chamber or the temperature changing chamber is 1, the current stop state of the compressor is maintained firstly, and when the temperature of the refrigerating chamber or the temperature changing chamber is increased to the preset starting temperature, the compressor is controlled to start. And simultaneously controlling the opening of the fan and the corresponding air door. And if the starting marker bit of the refrigerating chamber is 1, controlling the refrigerating chamber air door corresponding to the refrigerating chamber to open. And if the starting marker bit of the temperature-varying chamber is 1, controlling the air door of the temperature-varying chamber corresponding to the temperature-varying chamber to open. And if the starting flag bits of the refrigerating chamber and the temperature-varying chamber are both 1, simultaneously controlling the opening of the refrigerating chamber air door corresponding to the refrigerating chamber and the temperature-varying chamber air door corresponding to the temperature-varying chamber.
