Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of household appliances. More specifically, the present application relates to a refrigerator. Background Art

[0002] Refrigerators with a sterilization function adopt ion purification technology.

[0098] To make the objectives, implementation manners and advantages of this application clearer, the following will clearly and completely describe the exemplary implementation manners of this application with reference to the accompanying drawings in the exemplary embodiments of this application. Obviously, the described exemplary embodiments are only a part rather than all of the embodiments of this application.

[0099] It should be noted that the brief description of the terms in this application is only for facilitating the understanding of the subsequent described implementation manners, rather than intending to limit the implementation manners of this application. Unless otherwise specified, these terms should be understood in their ordinary and common meanings.

[0100] In addition, the terms "include" and "have" and any of their variations are intended to cover but not exclusively include. For example, a product or device including a series of components does not necessarily have to be limited to those components clearly listed, but may include other components not clearly listed or inherent to these products or devices.

[0101] An ion generator can be set in the refrigerator. By generating ions through the ion generator, the ions can circulate with the wind and take effect in the refrigerator space to achieve the effect of sterilization and odor removal.

[0102] Currently, ion generators are usually integral types, that is, the main emission component and the emitter are set as a whole at a certain fixed position. For example, they are set in the air duct corresponding to the refrigerating chamber, resulting in that this ion generator can only sterilize and remove odors from the area where it is located, and cannot sterilize and remove odors from multiple areas in the refrigerator.

[0103] If ion generators are separately provided in multiple regions, such as the freezer compartment, the refrigerating compartment, the variable temperature compartment, etc., it will result in relatively high production costs.

[0104] Furthermore, the sterilization and odor removal of multiple regions of the refrigerator can be achieved through a split-type ion generator, that is, multiple emitters are provided and the emitters are extended so that they take effect in different regions of the refrigerator.

[0105] However, how to deploy the split-type ion generator on a multi-system refrigerator so that the ion generator takes effect in multiple regions is an urgent problem to be solved.

[0106] Therefore, the present application provides a refrigerator, which is arranged inside the refrigerator by connecting the main emitting component and the secondary component (i.e., the extended emitting unit) of the ion generator through multiple high-voltage connectors, so that the ion generator takes effect in multiple regions, thereby meeting the sterilization and odor removal requirements of multiple compartments.

[0107] The technical solutions of the present application will be described in detail below in conjunction with specific embodiments. These specific embodiments can be combined with each other or exist independently. For the same or similar concepts or processes, they may not be described again in some embodiments. The embodiments of the present application will be described below in conjunction with the drawings.

[0111] Exemplarily, Figure 1 the refrigerator may be a single-system refrigerator (multiple compartments share one evaporator for refrigeration) or a multi-system refrigerator. Among them, the multi-system refrigerator may include a dual-system refrigerator (the freezer compartment and the refrigerating compartment use different evaporators for refrigeration) or a triple-system refrigerator (the freezer compartment, the refrigerating compartment, and the variable temperature compartment use different evaporators for refrigeration), etc.

[0112] In one possible implementation, the variable temperature compartment may include a first variable temperature compartment and a second variable temperature compartment. The above refrigerator may also be a quadruple-system refrigerator, that is, the freezer compartment, the refrigerating compartment, the first variable temperature compartment, and the second variable temperature compartment use different evaporators for refrigeration.
