DETAILED DESCRIPTION

[0028] The present invention will be described in detail in conjunction with embodiments shown in the figures. However, the embodiments are not intended to limit the present invention. Structural, methodogical or function variations made by those having ordinary skill in the art according to these embodiments are all comprised in the protection scope of the present invention.

[0029] In the description of specific embodiments of the present invention, terms indicating orientational or positional relationship such as "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "bottom", "in" and "out" is orientational or positional relationship based on what is shown in the figures, or the terms are used to describe mutual positional relationship of components in the vertical, perpendicular or gravitational direction, and the vertical direction refers to the up-down direction of the paper shown in the figures; "in" and "out" usually refer to the inside and outside of the cavity relative to the cavity.

[0030] As shown in FIG. 1 through FIG. 5, a first embodiment of the present invention discloses a household appliance, and the household appliance in the present embodiment may be any household appliance that needs a power supply line device 20, for example, a refrigerator, a freezer, a washing machine, an air conditioner, microwave or oven etc. Preferably, the household appliance is any type of smart/intelligent household appliance. Specifically, the household appliance is a refrigerator in the present embodiment.

[0031] The household appliance comprises a cabinet having a chamber, and the chamber may be divided into different numbers of compartments as needed. The present invention further discloses a power supply line device 20 for powering the household appliance. One end of the power supply line device 20 extends into the cabinet, and the other end of the power supply line device 20 is connected to an external power supply.

[0032] The power supply line device 20 comprises a line body 22, a plug 24 disposed at one end of the line body 22, and a line body fixing structure 26 disposed at the other end of the line body 22 away from the plug 24, wherein the line body fixing structure 26 is used to fix the line body 22 to the household appliance. Specifically, the line body fixing structure 26 is used to fix the line body 22 to the cabinet of the household appliance.

[0033] The power supply line device 20 further comprises an environmental parameter identifier 28 which is used to collect environmental parameters outside the household appliance. The refrigerator further comprises a control system and a refrigeration system connected with the control system. The environmental parameters collected by the environmental parameter identifier 28 are transmitted to the control system, and the control system receives and analyzes the environmental parameters, and then generates corresponding control instructions according to different environmental parameters. The above control instructions are transmitted to the refrigeration system, and the refrigeration system performs corresponding refrigeration or other operations according to different control instructions.

[0034] In the preferred embodiment, since the power supply line device 20 for power supply is provided with the environmental parameter identifier 28 which may collect environmental parameters such as ambient temperature and/or ambient humidity, it is unnecessary to separately provide corresponding signal lines and the environmental parameter identifier 28 and corresponding mounting structures, which makes the structure simpler and convenient to mount. In addition, the environmental parameter identifier 28 is not affected by the temperature of the cabinet, and the collected environmental parameters really reflect the environment outside the cabinet, so that the collected environmental parameters are more accurate. As a result, the control system can perform specific control better according to the external environment.

[0035] The line body fixing structure 26 is fixed to the cabinet, and the environmental parameter identifier 28 is located outside the cabinet. Usually, a fixing hole is provided on the cabinet, and the line body 22 passes through the fixing hole. In order to make the affixation of the line body 22 firmer, part of the line body fixing structure 26 may extend into the fixing hole. Certainly, the line body fixing structure 26 may also be arranged to be completely located outside the fixing hole. A detachable fastening structure such as a bolt may be used to fix the line body fixing structure 26 to the cabinet. Certainly, the line body fixing structure 26 may also be adhered to the outside of the cabinet by using an adhesive. The term "detachable" usually means detaching a corresponding structure with or without a tool without damaging the component.

[0036] Furthermore, the environmental parameter identifier 28 is disposed on the line body 22. Specifically, the environmental parameter identifier 28 is disposed adjacent to the plug 24. Such an arrangement makes the environmental parameter identifier 28 farther away from the cabinet, and the collected environmental parameters are more accurate. The environmental parameter identifier 28 comprises a temperature sensor and/or a humidity sensor. That is to say, the environmental parameter identifier 28 may be configured to include only one sensor for collecting one parameter, or configured to include a plurality of sensors for collecting two or more parameters.

[0037] The environmental parameter identifier 28 is detachably disposed on the line body 22. Certainly, the environmental parameter identifier 28 may also be integrally integrated into the power supply line device 20, i.e., the environmental parameter identifier 28 is set to be non-detachable, which will be described in detail in the following embodiments. Here, the term "non-detachable" here means that the environmental parameter identifier 28 cannot be detached with or without a tool without damaging the power supply line device 20, that is to say, the power supply line device 20 must be damaged if the environmental parameter identifier 28 is detached.

[0038] The line body 22 is provided with an accommodating space, and the environmental parameter identifier 28 is accommodated in the accommodating space. Furthermore, the line body 22 is provided with a signal interface. When the environmental parameter identifier 28 is mounted in the accommodating space, the environmental parameter identifier 28 is interfaced with the signal interface to perform signal transmission. Furthermore, for the sake of safety and reliability, the line body 22 is provided with a cover body 30 for at least partially covering the environmental parameter identifier 28. The cover body 30 can be opened when the environmental parameter identifier 28 needs to be replaced, and the cover body 30 may cover the environmental parameter identifier 28 again after the replacement of the environmental parameter identifier 28 is completed. In the preferred embodiment, when the cover body 30 is opened, the cover body 30 is completely detached from the line body 22, that is, the cover body 30 is completely separated from the line body 22. After the environmental parameter identifier 28 is replaced duly, the cover body 30 may be mounted on the line body 22 again. Certainly, the cover body 30 may also be configured in a way that the cover body 30 is not separated from the line body 22 when the cover body 30 is opened, the cover body 30 has an open state and a closed state, and the cover body 30 may be operated to be movable between the open state and the closed state. When the cover body 30 is moved to the open state, the environmental parameter identifier 28 may be replaced. After the replacement is completed, the cover body 30 may be operated to move to the closed state. Preferably, the cover body 30 may be operatively rotated between the open state and the closed state, to achieve the transition between the open state and the closed state.

[0039] Furthermore, the cover body 30 is snap-connected to the line body 22, the cover body 30 is an injection-molded member, the cover body 30 has a raised snap-fitting portion, and the cover body 30 is snap-fitted to the line body 22 by utilizing certain elasticity of the cover body 30 as the injection-molded member. In addition, in order to make the environmental parameter identifier 28 more sensitive and the collected parameters more accurate, the cover body 30 is provided with a plurality of through holes 32. Specifically, the plurality of through holes 32 are arranged at an interval in an extension direction of the line body 22.

[0040] The power supply line device 20 further comprises a signal connector 34, the signal connector 34 and the environmental parameter identifier 28 are located on both sides of the line body fixing structure 26, the environmental parameter identifier 28 is electrically connected to the signal connector 34, and the signal connector 34 is pluggably connected to the control system.
