In the description of the present application, the meaning of "a plurality" means two or more unless otherwise specified.

At present, the use of refrigeration equipment such as refrigerators, freezers and the like is popularized, and a great deal of convenience is provided for life of people. However, food that has just been placed in the cold storage device takes a period of time to cool. In the cooling process, harmful bacteria carried by food can be rapidly propagated, and the number of the bacteria is gradually increased along with the increase of the storage time of the food, so that the food stored in the refrigeration equipment for a long time is polluted by the bacteria, the fresh-keeping effect of the food is influenced, and even the health of people is harmed.

Generally can be provided with bacteria removing device among the current refrigeration plant, however, bacteria removing device among the current refrigeration plant, no matter store food among the refrigeration plant, bacteria removing device is in the degerming state always, and the energy consumption is great.

To solve the problems in the prior art, embodiments of the present application provide a refrigeration device, which may be a refrigerator, an ice chest, or the like. A sterilization drawer is arranged in a refrigerating chamber of the refrigerating equipment, and is provided with a switch detection device, a temperature detection device, a pressure detection device, a sterilization device and a control device. Controlling means, can adjust bacteria removing device's operation gear according to the weight of the bacteria removing drawer that the switch detection device detected the switch state of the bacteria removing drawer, the temperature in the bacteria removing drawer that the temperature-detecting device detected and the bacteria removing drawer that the pressure detection device detected, so this cold storage plant's bacteria removing drawer is equipped with bacteria removing device's degerming effect is better, and more energy-conserving.

Fig. 1 shows a structure of a degerming drawer arranged in a refrigerating chamber of a refrigerating device provided by the embodiment of the application. As shown in fig. 1, the sterilization drawer is provided with: the automatic sterilization device comprises a switch detection device 01, a temperature detection device 02, a pressure detection device 03, a sterilization device 04 and a control device 05 connected with the switch detection device 01, the temperature detection device 02, the pressure detection device 03 and the sterilization device 04.

The switch detection device 01 is used for detecting the opening and closing state of the degerming drawer, and the opening and closing state is an opening state or a closing state.

And the temperature detection device 02 is used for detecting the temperature in the degerming drawer.

And the pressure detection device 03 is used for detecting the weight of the sterilizing drawer.

For example, in the embodiment of the present application, the switch detection device 01 may be a drawer switch sensor, the temperature detection device 02 may be a temperature sensor, and the pressure detection device 03 may be a planar piezoelectric sensor.

Of course, in practical applications, the switch detection device 01 may be another type of detection device capable of detecting the switch state of the sterilization drawer, the temperature detection device 02 may be another type of detection device capable of detecting the temperature, and the pressure detection device 03 may be another type of detection device capable of detecting the weight of the sterilization drawer.

And the sterilizing device 04 is used for sterilizing the inside of the sterilizing drawer.

Wherein, degerming device 04 is provided with a plurality of gears of N according to the intensity of degerming ability, and the degerming ability of every gear is different in a plurality of gears of N, and N is more than or equal to 2's integer.

Optionally, the degerming capability is gradually enhanced from the first gear to the nth gear. The first gear is the lowest gear, which indicates the weakest sterilization capability. The Nth gear is the highest gear and represents the strongest degerming capability.

The control device 05 is configured to: after determining that the switch detection device 01 detects that the sterilizing drawer is switched from the open state to the closed state, controlling the pressure detection device 03 to detect the weight of the sterilizing drawer; when the weight of the degerming drawer detected by the pressure detection device 03 is determined to exceed a preset value, the degerming device 04 and the temperature detection device 02 are controlled to start to operate, and the operating gear of the degerming device 04 is the Nth gear; after determining that the temperature detected by the temperature detecting device 02 is reduced to the preset temperature, controlling the operating gear of the sterilizing device 04 to be reduced from the Nth gear to the first gear.

The switch detection device 01 may detect the switch state of the sterilization drawer, and may transmit switch switching information to the control device 05 when the switch detection device 01 detects the switch state switching of the sterilization drawer. When the opening/closing state of the sterilization drawer is switched from the open state to the closed state, the switch detection device 01 may transmit switch switching information of the sterilization drawer, which is detected to be switched from the open state to the closed state, to the control device 05. The control device 05 controls the pressure detection device 03 to detect the weight of the sterilization drawer after receiving the switch switching information (i.e. the information that the sterilization drawer is switched from the open state to the closed state), i.e. controls the pressure detection device 03 to be activated when the control device 05 determines that the switch detection device 01 detects that the sterilization drawer is switched from the open state to the closed state.

After the pressure detection device 03 is started, when the weight of the degerming drawer detected by the pressure detection device 03 exceeds a preset value, a message is sent to the control device 05 to instruct the control device 05 to start controlling the degerming device 04 and the temperature detection device 02 to start operation.

The preset value is a numerical value determined in advance manually. For example, in the embodiment of the present application, the preset value may be a weight value that is greater than the weight of an empty sterilization drawer (i.e., a sterilization drawer that is not filled with any food).

Therefore, the sterilization device 04 is closed in the sterilization drawer, and starts to be started after food is put into the sterilization drawer, so that compared with the existing sterilization device 04 which is always in a sterilization state regardless of whether food is stored in the refrigeration equipment, the sterilization device 04 provided by the embodiment of the application saves energy.

Optionally, the control device 05 is further configured to: and when the switch detection device 01 detects that the sterilizing drawer is switched from the closed state to the open state, controlling the sterilizing device 04 and the temperature detection device 02 to stop running.

When the opening/closing state of the sterilization drawer is switched from the closed state to the open state, the switch detection device 01 may transmit switch switching information of the sterilization drawer switched from the closed state to the open state, which is detected, to the control device 05. The control device 05 controls the sterilizing device 04 and the temperature detecting device 02 to stop operating upon receiving the switch switching information (i.e., information for switching the sterilizing drawer from the closed state to the open state).

Alternatively, after the control device 05 controls the sterilizing device 04 and the temperature detecting device 02 to stop operating, the control device 05 is further configured to: and if the switch detection device 01 detects that the duration that the degerming drawer is in the open state is greater than or equal to the third preset duration, sending alarm information.

Wherein the third preset time period is a parameter determined in advance. In the embodiment of the present application, the third preset time period may be adjusted according to a user's requirement, and when the speed of taking and putting food is faster when the user uses the refrigeration apparatus, the third preset time period may be relatively shorter, for example, may be set to one minute. When the speed of taking and putting the food is slow when the user uses the refrigeration apparatus, the third preset time period may be relatively long, for example, set to two minutes.

To avoid energy consumption by the user due to forgetting to close the sterilization drawer after opening the sterilization drawer. After the control device 05 receives the information that the sterilization drawer is switched from the closed state to the open state sent by the switch detection device 01, if the control device 05 does not receive the information that the sterilization drawer is switched from the open state to the closed state sent by the switch detection device 01 within the third preset time period, an alarm message can be sent to the user, the user is prompted to close the sterilization drawer in time, and energy consumption is reduced.

In addition, when a user opens the degerming drawer and puts food in, the temperature of the food and the temperature of the air can cause the temperature in the degerming drawer to suddenly increase, and harmful bacteria carried by the food can quickly breed at the moment. Therefore, in order to restrain the propagation process of the harmful bacteria before the harmful bacteria rapidly propagate, after the control device 05 determines that the sterilization drawer is closed and food is in the sterilization drawer, the operating gear of the sterilization device 04 needs to be controlled to be adjusted to the maximum gear (i.e., the nth gear) to improve the sterilization effect of the sterilization device 04.

In addition, after the control device 05 starts to control the sterilization device 04 and the temperature detection device 02 to start operation, the temperature detection device 02 may send the detected temperature to the control device 05, and when the temperature sent by the temperature detection device 02 is received by the control device 05 and is the preset temperature, the propagation process of harmful bacteria carried by food in the sterilization drawer is substantially inhibited. At this time, the control device 05 may control the operation gear of the sterilizing device 04 to be lowered to the first gear to reduce power consumption.

The preset temperature is artificially determined in advance.

Optionally, after controlling the sterilization device 04 and the temperature detection device 02 to start operating, the control device 05 is further configured to: and if the temperature detected by the temperature detection device 02 after the second preset time is determined not to be reduced to the preset temperature, sending alarm information.

Wherein the second preset time period is a parameter determined in advance. For example, in the embodiment of the present application, the degerming drawer is applied to a refrigeration device such as a refrigerator, an ice chest, etc., so that the second preset time period can be determined according to the refrigeration effect of the refrigeration device.

After the second preset time, if the temperature detected by the temperature detection device 02 received by the control device 05 is not reduced to the preset temperature, it indicates that the refrigeration effect of the refrigeration equipment where the degerming drawer is located may be problematic, and the degerming drawer needs to be overhauled in time to ensure the fresh-keeping effect of food in the degerming drawer.

Optionally, after controlling the operation gear of the degerming device 04 to be lowered from the nth gear to the first gear, the control device 05 is further configured to: when the operation time of the degerming device 04 at the ith gear is equal to a first preset time corresponding to the ith gear, controlling the gear of the degerming device 04 to be the current operation gear plus one until the Nth gear is reached; wherein i is more than or equal to 1 and less than N.

Since the food stored in the degerming drawer can also breed bacteria along with the increase of the storage time, in order to improve the degerming effect of the degerming device 04, the control device 05 can adjust the operating gear of the degerming device 04 along with the change of time after controlling the operating gear of the degerming device 04 to be reduced to the first gear.

Illustratively, when the degerming capability of the degerming device 04 includes 3 gears, the control device 05 controls the gear of the degerming device 04 to be increased to the second gear after controlling the operation gear of the degerming device 04 to be decreased from the nth gear to the first gear, when the operation time of the degerming device 04 in the first gear is equal to the first preset time corresponding to the first gear. When the control device 05 controls the degerming device 04 to operate in the second gear for a time period equal to a first preset time period corresponding to the second gear, the gear of the degerming device 04 is controlled to be shifted to the third gear. Finally, the control device 05 controls the sterilizing device 04 to continue operating in the third gear until the control device 05 receives the information that the sterilizing drawer is switched from the closed state to the open state.

Fig. 2 shows a coordinate diagram of a gear shift when the sterilization capacity of the sterilization device 04 comprises 3 gears. As shown in FIG. 2, at time t0, the operating range of the bacteria elimination device 04 is reduced from the third range to the first range. At time t1, the operating duration Δ t1 of the degerming device 04 in the first gear is equal to the first preset duration corresponding to the first gear, and the control device 05 controls the gear of the degerming device 04 to be shifted up to the second gear. At time t2, the operating time Δ t2 of the degerming device 04 in the second gear is equal to the first preset time corresponding to the second gear, at which time the control device 05 controls the gear of the degerming device 04 to be shifted up to the third gear. Since the third gear has reached the highest gear of the sterilizing device 04, after time t2 the control device 05 controls the sterilizing device 04 to continue operating in the third gear.

Since the food has a shelf life, optionally, when the control device 05 controls the sterilization device 04 to continuously operate in the third gear for more than a certain length, the control device 05 may send an alarm message to the user to prompt the user to clean the food in the sterilization drawer in time.

In addition, in order to further improve the sterilization effect of the sterilization device 04, the operation time of the sterilization device 04 in each gear may be different.

Optionally, the control device 05 is further configured to: and determining a first preset time corresponding to the ith gear according to the weight of the degerming drawer detected by the pressure detection device 03.

In particular, when the weight of the sterilization drawer detected by the pressure detection device 03 is small, the control device 05 can control the operation time of the sterilization device 04 in the low gear to be relatively long and the operation time in the high gear to be relatively short. When the weight of the degerming drawer detected by the pressure detection device 03 is large, the control device 05 can control the running time of the degerming device 04 in the low gear to be relatively short, and the running time of the degerming device 04 in the high gear to be relatively long.

It should be noted that the embodiment of the present application only provides a way for the control device 05 to control and adjust the operating gear of the degerming device 04, and in practical applications, the control device 05 may also control and adjust the operating gear of the degerming device 04 by other ways. For example, the control device 05 determines that the operating duration of the i-th gear of the sterilizing device 04 is equal to a first preset duration corresponding to the i-th gear, and controls the gear of the sterilizing device 04 to be the current operating gear plus one until the N-th gear is reached. Then, the gear of the degerming device 04 is controlled to be reduced by one for the current operation gear in the same way until the first gear is reached. That is, the control device 05 controls the shift position of the sterilizing device 04 to be cyclically operated between the first shift position and the nth shift position.
