Detailed Description
In order to make the aforementioned objects, features and advantages of the embodiments of the present invention more comprehensible, specific embodiments accompanied with figures are described in detail below.
The embodiment of the invention provides a sterilization system, and referring to fig. 1, a schematic diagram of an arrangement of the sterilization system in a refrigeration appliance in the embodiment of the invention is given. FIG. 2 shows a schematic view of another arrangement of a sterilization system in an embodiment of the present invention in a refrigeration appliance. The structure of the sterilization system 20 will be described with reference to fig. 1 and 2.
In an implementation, the sterilization system 20 may be disposed in the storage compartment 10 of the refrigeration apparatus 100, and the sterilization system 20 may include a sterilization factor generation device 21, a concentration detection device 22, and a controller (not shown in fig. 1 and 2). The sterilizing factor generating device 21 can supply the sterilizing factor to the storage compartment 10 of the refrigeration appliance 100 when turned on. The degerming factor may react or bind with off-flavor molecules, such as mold, odor, etc., within the storage compartment 10 to remove the off-flavor from the storage compartment 10.
In the embodiment of the present invention, the degerming factor generating device 21 is an ion generating device. The ion generating device can generate negative ions and ozone.
In a specific implementation, the concentration detection device 22 is disposed in the storage compartment 10, and is capable of detecting the concentration of the degerming factor in the storage compartment 10 and outputting the detected concentration of the degerming factor to the controller.
In the embodiment of the present invention, the concentration detection device 22 is different according to the type of the degerming factor. For example, the sterilization factor includes negative ions, and the concentration detection device 22 includes a negative ion detection sensor or other device capable of detecting the concentration of negative ions. As another example, the sterilization factor includes ozone and the concentration detection sensor includes an ozone sensor or other sensor capable of detecting the concentration of ozone.
When the concentration of the degerming factor satisfies the first set condition, the controller may control the degerming factor generating device 21 to be turned on. When the concentration of the degerming factor satisfies the second set condition, the controller may control the degerming factor generating device 21 to be turned off to stop supplying the degerming factor to the storage compartment 10. The controller can be used for multiplexing the existing control device of the refrigerator, and can also be independently provided with one controller for controlling the degerming factor generation device and the concentration detection device.
In embodiments of the present invention, the sterilization factor may include negative ions and ozone. The first setting condition may include any one of: the negative ion concentration is lower than a first threshold, the ozone concentration is lower than a second threshold, the negative ion concentration is lower than the first threshold, and the ozone concentration is lower than the second threshold.
In the embodiment of the present invention, the second setting condition may include any one of: the ozone concentration is higher than the safety threshold, the negative ion concentration is higher than the third threshold, the ozone concentration is higher than the safety threshold, and the negative ion concentration is higher than the third threshold.

When ozone concentration is higher than the safety threshold, in time close degerming factor generating device 21 to reduce the production of ozone, avoid local anion or ozone concentration too high, can avoid ozone concentration too high harm that causes the human body when taking into account the degerming effect.
As can be seen from the above, the concentration detection device 22 is provided in the storage compartment 10 of the refrigeration device 100 and can be used to detect the concentration of the sterilization factor in the storage compartment 10. The concentration detecting device 22 outputs the detected concentration of the degerming factor to the controller, and when the concentration of the degerming factor meets a first set condition, the controller controls the degerming factor generating device 21 to be opened to provide the degerming factor to the storage compartment 10 so as to ensure the degerming effect. When the concentration of the degerming factor meets the second set condition, the controller controls the degerming factor generating device 21 to be closed, and stops supplying the degerming factor to the storage compartment 10, so as to save energy consumption. The controller can control degerming factor generating device 21 to open or close according to the degerming factor concentration in the storage room 10 that concentration detection device 22 detected to can open and close degerming factor generating device 21 in time according to the concentration condition of the degerming factor in the storage room 10, avoid degerming factor generating device 21 inoperative work, consequently can be when taking into account the degerming effect, reduce the energy consumption of degerming system 20.

Because the setting position of the concentration detection device 22 is far away from the setting position of the degerming factor generation device 21, the concentration detection device 22 can detect the concentration of the degerming factor at a far position from the degerming factor generation device 21, so that the opening or closing of the degerming factor generation device 21 can be controlled according to the concentration of the degerming factor detected by the concentration detection device 22.
In an embodiment of the invention, referring to fig. 1, the concentration detection device 22 is suspended below the partition in the longitudinally lower subspace within the storage compartment 10.

The display device is coupled with the concentration detection device 22 or the controller, and can display the concentration, the average ion concentration or the maximum ion concentration of the degerming factor detected by the concentration detection device 22 in real time, so that a user can conveniently and intuitively know the concentration condition of the degerming factor in the current storage room 10, and therefore the degerming process can be intuitively known, and the user experience and the control feeling can be enhanced.
