[0033] At present, most refrigerators display content on the door panel in two ways: one is to use LED chips with shading plates, such as digital tubes; the other is to use LCD screens. The display area of ​​these two methods is generally small, and users need to be at a relatively close distance to see the displayed content clearly. When it is necessary to display parameters and logo patterns in a large area, the first method requires a large number of LED chips and a light guide plate to make the LED chips emit light evenly, which has the disadvantages of increased failure rate, complex structure, high cost and high energy consumption; the second method requires a large-size LCD screen, which results in overkill, and the cost and energy consumption cannot be controlled.

[0034] Based on this, the embodiment of the utility model provides a refrigerator door and a refrigerator, which can realize large-area display of parameters, logo patterns and other contents at low cost and low energy consumption.

[0035] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings.

[0036] Reference Figure 1 The first embodiment of the utility model provides a refrigerator door 100, comprising a bottom plate 110, a transparent panel 120 and a driving module 130, wherein:

[0037] The bottom plate 110 is divided into a plurality of display partitions 111, each display partition 111 is respectively covered with an electrically controlled dimming film 900, and a plurality of electrically controlled dimming films 900 are combined to form a parameter display pattern and / or a status mark pattern; the transparent panel 120 covers a plurality of electrically controlled dimming films 900, and cooperates with the bottom plate 110 to clamp and fix the electrically controlled dimming films 900; the driving module 130 is respectively connected to a plurality of electrically controlled dimming films 900, and is used to control the power on and off of a plurality of electrically controlled dimming films 900, so that the cabinet door 100 displays the operating parameters and / or status marks of the refrigerator.

[0038] It should be noted that the parameter display pattern formed by combining multiple electrically controlled dimming films 900 can have many different forms, for example, Figure 1 As shown, first, seven electrically controlled dimming films 900 are combined to form a pattern shape of an Arabic numeral "8", and then a two-digit parameter display pattern is formed by combining the pattern shape of two Arabic numerals "8" plus the pattern shape of the decimal point formed by one electrically controlled dimming film 900. In addition, a unit pattern shape can be added after the pattern shape of the last Arabic numeral 8, such as the unit pattern shape "℃" corresponding to the temperature parameter formed by two electrically controlled dimming films 900. It can be understood that the parameter position corresponding to the parameter display pattern can be more than two, for example, it can be four parameter positions with two decimal points, so that most temperature parameters on the refrigerator can be displayed. In some embodiments, the parameter display pattern on the door 100 of the refrigerator is used to display the current temperature of the internal drawer corresponding to the door 100, or to display the target set temperature of the internal drawer corresponding to the door 100, or to display the weather temperature in the current area, etc.

[0039] Similarly, the status mark pattern formed by the electric-controlled dimming film 900 can also have a variety of different forms. For example, the status mark pattern can be a mark pattern corresponding to the preset function of the refrigerator. The preset function of the refrigerator can refer to the defrost function of the refrigerator, the fresh-keeping function of the variable temperature drawer, the quick freezing function of the refrigerator freezer, etc. In addition, the status mark pattern can also include the brand trademark pattern of the refrigerator.

[0040] According to the refrigerator door 100 provided by the embodiment of the utility model, a plurality of display partitions 111 are divided on the bottom plate 110 of the refrigerator door 100, and the electrically controlled dimming film 900 is covered on each display partition 111, and then the transparent panel 120 cooperates with the bottom plate 110 to clamp and fix the electrically controlled dimming film 900, and finally the driving module 130 controls several of the plurality of electrically controlled dimming films 900 to be powered on, and the display state of the electrically controlled dimming film 900 after being powered on is different from the display state of the electrically controlled dimming film 900 not powered on, and is different from the display state of other electrically controlled dimming films not provided with the electrically controlled dimming film 900, so that after being powered on, the display state of the electrically controlled dimming film 900 is different from that of the electrically controlled dimming film 900 not powered on, and is different from that of other electrically controlled dimming films 900 not provided with the electrically controlled dimming film 900. The electrically controlled dimming film 900 can display the operating parameters and / or status signs of the refrigerator on the door 100. The electrically controlled dimming film 900 can be set according to the size of the display partition 111, so that parameters, logo patterns and other contents can be displayed on the door 100 of the refrigerator in a large area. Moreover, the electrically controlled dimming film 900 has the advantage of low cost compared to LCD screens of the same size, and has the advantages of simple structure, reduced failure rate and low energy consumption compared to the display method using multiple LED chips in conjunction with a light guide plate. Therefore, the door 100 of the refrigerator can display parameters, logo patterns and other contents on a large area at low cost and low energy consumption.

[0041] In the refrigerator door 100 provided in some embodiments of the present invention, the electrically controlled dimming film 900 adopts a liquid crystal electrically controlled dimming film. The liquid crystal electrically controlled dimming film can realize the conversion of glass between transparent and opaque by adjusting the voltage. Specifically, the liquid crystal electrically controlled dimming film can adjust the optical properties of the material under the action of the electric field through the PDLC (polymer dispersed liquid crystal) technology. The technology adopts polymer dispersed liquid crystal material. The arrangement structure of the liquid crystal material molecules changes under the action of the electric field, thereby changing the transparency of the liquid crystal electrically controlled dimming film itself. Under normal conditions, the arrangement of the liquid crystal polymer inside the liquid crystal electrically controlled dimming film is irregular, and the incident light dissipates heat at the liquid crystal polymer. At this time, the liquid crystal electrically controlled dimming film presents a milky white opaque state, that is, the electrically controlled dimming film 900 is in a frosted state when it is powered on and when it is powered off. After power is turned on, the liquid crystal polymer is rearranged under the influence of the electric field, and the irregular arrangement changes to a directional regular arrangement. The incident light can pass through the liquid crystal polymer mostly or completely. At this time, the liquid crystal electrically controlled dimming film presents a transparent state.

[0042] In the refrigerator door 100 provided in some embodiments of the present invention, the area of ​​the bottom plate 110 other than the display partition 111 is also covered with an electrically controlled dimming film 900 .

[0043] It can be understood that each display partition 111 on the base plate 110 is respectively covered with an electrically-controlled dimming film 900, and the area other than the display partition 111 is also covered with an electrically-controlled dimming film 900, so that all areas of the box door 100 are covered with the electrically-controlled dimming film 900, and when all the electrically-controlled dimming films 900 are not powered on, all areas of the box door 100 have the same display state. When the electrically controlled dimming film 900 controlling the corresponding display partition 111 is energized to display parameters, logo patterns and other contents in a large area on the box door 100, the electrically controlled dimming film 900 corresponding to the remaining display partitions 111 is not energized, and the electrically controlled dimming films 900 corresponding to areas outside the display partitions 111 are also not energized. These electrically controlled dimming films 900 that are not energized have the same display state, that is, on the box door 100, except for the displayed parameters and logo patterns, the display states of the remaining areas are the same, and the non-display partition on the box door, the display partition 111 corresponding to the electrically controlled dimming film 900 in the energized state, and the display partition 111 corresponding to the electrically controlled dimming film 900 in the powered-off state will not have different display states, thereby avoiding affecting the user's visual experience.

[0044] In the refrigerator door 100 provided in some embodiments of the present invention, the bottom plate 110 and the transparent panel 120 are both made of tempered glass.

[0045] It can be understood that the bottom plate 110 and the transparent panel 120 are both made of tempered glass. The bottom plate 110, the electrically controlled dimming film 900 and the transparent panel 120 form a laminated glass panel with good transparency, which can make the refrigerator door 100 have a better display effect when displaying parameters, logo patterns and other contents.

[0046] Reference Figure 2 In the refrigerator door 100 provided in some embodiments of the present invention, the door 100 also includes a first EVA film 140 located between the bottom plate 110 and the electrically-controlled dimming film 900 and a second EVA film 150 located between the transparent panel 120 and the electrically-controlled dimming film 900.

[0047] It is understandable that by providing an EVA film between the electrically-controlled dimming film 900 and the bottom plate 110 and the transparent panel 120 , the safety performance of the laminated glass panel composed of the bottom plate 110 , the electrically-controlled dimming film 900 and the transparent panel 120 can be improved.

[0048] Reference Figure 3 In the refrigerator door 100 provided in some embodiments of the present invention, conductive films 910 are provided on both sides of the electrically controlled dimming film 900, and the two conductive films 910 are correspondingly connected to the two power supply terminals of the driving module 130 through the conductive circuit 920.

[0049] It should be noted that the conductive films 910 arranged on the two sides of the electrically-controlled dimming film 900 can be ITO (Indium-Tin-Oxide) conductive films. The edges of the ITO conductive films 910 are connected to the power supply terminals of the driving module 130. The driving module 130 supplies power through the power supply terminals, so that an electric field is formed between the two conductive films 910, thereby changing the arrangement of the liquid crystal polymer 930 inside the electrically-controlled dimming film 900 to a regular arrangement.

[0050] In the refrigerator door 100 provided in some embodiments of the present invention, the area corresponding to the parameter display pattern and / or the status mark pattern is larger than half of the area corresponding to the door 100 .

[0051] It can be understood that the box door 100 provided in this embodiment is more suitable for displaying parameter display patterns and / or status mark patterns in large sizes, and has the advantage of low cost compared to LCD screens of the same size. Compared with the method of using multiple LED chips in conjunction with a light guide plate display, it has the advantages of simple structure, reduced failure rate and low energy consumption.

[0052] In addition, the second aspect of the present invention provides a refrigerator, including the door 100 of the first aspect and a human body sensing device connected to a driving module 130, wherein the driving module 130 is used to control the electric control dimming film 900 to be powered on when the human body sensing device detects a human body.

[0053] What can be done immediately is to set up a human body sensing device, and when the user's body is detected by the human body sensing device, the electric control dimming film 900 is controlled to be powered on, so that the electric control dimming film 900 is in a power-off state when the user is not present, thereby saving energy consumption and avoiding energy waste; when the user is present and needs to check, the box door is controlled to display the operating parameters and status signs of the refrigerator in a large area, thereby improving the user experience.

[0054] In addition, it can also be understood that the refrigerator is generally provided with a plurality of doors 100. For example, the refrigerator is a double-door refrigerator, provided with two doors arranged up and down or two doors arranged left and right; the refrigerator can also be a three-door refrigerator, provided with three doors arranged up and down; the refrigerator can also be a four-door refrigerator such as a French door refrigerator or a cross door refrigerator. Different doors 100 can be provided with different display contents. For example, the drawer corresponding to one door is a refrigeration drawer, and the refrigeration temperature can be displayed on a large area on the panel of the door; another door can display the current weather temperature, and another door can display the function of the variable temperature drawer, etc.

[0055] According to the refrigerator provided by the embodiment of the utility model, a plurality of display partitions 111 are divided on the bottom plate 110 of the door 100, and the electrically controlled dimming film 900 is covered on each display partition 111, and then the transparent panel 120 cooperates with the bottom plate 110 to clamp and fix the electrically controlled dimming film 900, and finally the driving module 130 controls several of the plurality of electrically controlled dimming films 900 to be powered on, and the display state of the electrically controlled dimming film 900 after being powered on is different from the display state of the electrically controlled dimming film 900 not powered on, and is different from the display state of other electrically controlled dimming films not provided with the electrically controlled dimming film 900, so that the electrically controlled dimming film 900 after being powered on is different from the display state of the electrically controlled dimming film 900 not powered on, and is different from the display state of other electrically controlled dimming films 900 not provided with the electrically controlled dimming film 900, The dimming film 900 can display the operating parameters and / or status signs of the refrigerator on the door 100. The electrically controlled dimming film 900 can be set according to the size of the display partition 111, so that parameters, logo patterns and other contents can be displayed on the door 100 of the refrigerator in a large area. Moreover, the electrically controlled dimming film 900 has the advantage of low cost compared to LCD screens of the same size, and has the advantages of simple structure, reduced failure rate and low energy consumption compared to the display method using multiple LED chips in conjunction with a light guide plate. Therefore, the door 100 of the refrigerator can display parameters, logo patterns and other contents on a large area at low cost and low energy consumption.

[0056] It should be understood that in the present application, "at least one (item)" means one or more, and "plurality" means two or more.
