In a further scheme, the working time of the negative ion generator is controlled according to the range of the first environment temperature when the refrigeration door is opened and the current opening time of the refrigeration door; when the first ambient temperature is less than a first temperature threshold, performing: if the time length of the next starting is less than or equal to the first preset time length, controlling the negative ion generator to operate for the first working time length and then stopping; if the time of the next starting is longer than the first preset time and is less than or equal to the second preset time, controlling the negative ion generator to operate for the second working time and then stopping; if the time of the secondary starting is longer than the second preset time and is less than or equal to a third preset time, controlling the negative ion generator to operate for the third working time and then stopping; if the time length of the next starting is longer than the third preset time length, controlling the negative ion generator to run for a fourth working time length and then stopping; the first preset time length, the second preset time length and the third preset time length are sequentially increased in an increasing mode, and the first working time length, the second working time length, the third working time length and the fourth working time length are sequentially increased in an increasing mode.

Detailed Description

Example of the ion sterilization method for the refrigerator:

the ion sterilization method for the refrigerator is an application program applied to the refrigerator and used for performing sterilization control on the refrigerating chamber. Preferably, the refrigerator is provided with an anion generator, an ambient temperature sensing bulb, a refrigerating chamber temperature sensor, a refrigerating air door switch sensor and a refrigerating door switch sensor, and the structures of the anion generator, the ambient temperature sensing bulb, the refrigerating chamber temperature sensor, the refrigerating air door switch sensor and the refrigerating door switch sensor are set to be known by the technical personnel in the field and are not described in detail herein.

As shown in fig. 1, in the present embodiment, when the ion sterilization method for the refrigerator is operated, step S1 is executed first, and when the sterilization instruction is acquired, the refrigerator enters a sterilization state. When the refrigerator works, a user can send a sterilization instruction through a control panel of the refrigerator, and when the sterilization instruction is obtained, the refrigerator is controlled to enter a sterilization state, and sterilization operation is performed on the refrigerating chamber.

In this embodiment, referring to fig. 2, when entering the sterilization state, step S11 is executed first to determine whether to perform the first sterilization after power-on. When the refrigerator works, the running state of the refrigerator is recorded in real time, and whether the refrigerator is subjected to primary sterilization after being electrified or not can be determined by reading the running state. The first sterilization after power-on refers to the first sterilization operation after the power-on state is restored after power failure.

If it is determined that the initial sterilization is not performed after power-up, the next step may be performed. If the first sterilization after power-on is determined, step S12 is executed to control the working time of the ionizer according to the range of the current ambient temperature. Wherein, the working time of the anion generator is positively related to the range of the current environment temperature. The current ambient temperature is the temperature corresponding to the environment in which the refrigerator is located. In order to enable the refrigerating chamber to reach the specified sterilization standard within the specified time and reduce the energy consumption, the working time of the negative ion generator is controlled according to the range of the current environment temperature, so that the control rationality is improved.

In this embodiment, the step of controlling the operation time of the negative ion generator according to the range of the current ambient temperature includes: if the current environment temperature is lower than the first preset environment temperature, controlling the negative ion generator to operate for a first time and then stop; if the current environment temperature is greater than or equal to the first preset environment temperature and less than or equal to the second preset environment temperature, controlling the negative ion generator to run for a second time and then stop; and if the current ambient temperature is greater than the second preset ambient temperature, controlling the negative ion generator to operate for a third time and then stopping. The first preset environment temperature and the second preset environment temperature can be preset according to biological characteristics of bacteria, for example, staphylococcus aureus and escherichia coli are difficult to generate below 15 ℃, and can be set according to suitable survival temperatures of the staphylococcus aureus and the escherichia coli. In this embodiment, the first preset ambient temperature is set to range from 14 ℃ to 16 ℃, the second preset ambient temperature is set to range from 29 ℃ to 31 ℃, and preferably, the first preset ambient temperature is set to range from 15 ℃ and the second preset ambient temperature is set to range from 30 ℃. The first duration, the second duration and the third duration can be preset according to experimental data, and the first duration, the second duration and the third duration sequentially increase in an increasing manner, in this embodiment, a value range of the first duration is 13h to 15h, a value range of the second duration is 17h to 19h, a value range of the third duration is 21h to 23h, preferably, the first duration is 14h, the second duration is 18h, and the third duration is 22 h.

After entering the sterilization state, step S2 is executed to determine whether the sterilization state has been entered for the target period of time. The target duration can be preset according to experimental data, is greater than the third duration, and is timed from the moment when the sterilization is first started after power-on, in this embodiment, the target duration is 24 hours. The target duration is longer than the third duration because the negative ion generator generates air negative ions through high-voltage corona discharge, and the long-time operation is not beneficial to the subsequent service life of the negative ion generator, so that the negative ion generator is closed for a period of time after the long-time operation.

If the sterilization status does not reach the target duration, the process continues to step S2 for continuous monitoring. If the sterilization state is entered and the target time duration is reached, step S3 is executed to determine whether the refrigeration door is opened. When the sterilization state is entered and the target duration is reached, the current sterilization rate reaches the specified sterilization standard, and at the moment, the circular sterilization stage is entered. In the cyclic sterilization stage, the main factor influencing the sterilization effect is that the customer opens the refrigeration door and opens, and therefore, the refrigeration door needs to be monitored for opening and closing. The opening and closing of the refrigerating door can be detected through the refrigerating door opening and closing sensor.

The first ambient temperature is the temperature corresponding to the environment where the refrigerator is located when the refrigeration door is opened. When the refrigerating door is opened, the range of the first environment temperature and/or the working time of the refrigerating door when the refrigerating door is opened controls the working time of the anion generator, so that the working time of the anion generator is reasonably controlled by combining the environment temperature and the working time of the actual use of a user, the sterilizing and refreshing effect is improved, and the energy consumption is saved.
