[0079] Figure 1 This is a partial perspective schematic diagram of a drawer for a household appliance according to one aspect of an embodiment of the present application. Figure 1 One aspect of the embodiment of the present application relates to a household appliance 10 ( Figure 5 ) of the drawer 30. The drawer 30 may be a substantially square box body. The drawer 30 includes a storage space 32. The drawer 30 may store food, medicine, beverages and other items (not shown) through the storage space 32. The storage space 32 may be open upward so that items may be taken in and out through the top of the drawer 30 when the drawer 30 is pulled out.

[0080] The drawer 30 includes a front wall assembly 34 . Figure 2 yes Figure 1 A partial cross-sectional schematic diagram of a front wall assembly for a drawer of a household appliance is provided. Figure 2 As shown, the front wall assembly 34 is roughly plate-shaped. The front wall assembly 34 includes a main body 36, a light source assembly 38, and a pattern 40 provided on the main body 36. The main body 36 defines the storage space 32 from the front. The main body 36 includes a visible surface 42. The visible surface 42 is the front surface, outer surface, and main surface of the main body 36. The visible surface 42 is the front main outer surface of the drawer 30 that can be seen by the user. The light source assembly 38 includes a light source 44, and the light source 44 and the visible surface 42 are located on the same side of the pattern 40, and the light source 44 can illuminate the main body 36 to light up the pattern 40. The light source 44 and the visible surface 42 can be located outside the pattern 40. The visible surface 42 can be located outside the light source 44. The pattern 40 lit by the light source 44 outside the pattern 40 can be seen through the visible surface 42 outside the pattern 40, and the visual effect is better. The pattern 40 can include one or more of text, graphics, icons, symbols, logos, and logos.

[0081] The embodiment of the present application can help the drawer 30 used in the household appliance 10 to have a better visual effect, a more compact structure, and a better user experience of the household appliance 10. For example, the light source 44 of the embodiment of the present application can illuminate the main body 36 to light up the pattern 40. Compared with a drawer without a pattern and no light, the visual effect of the drawer 30 is better and the user experience is better, and / or, the light source 44 and the visible surface 42 of the embodiment of the present application are located on the same side of the pattern 40, the pattern 40 is lit in the air, the visual effect of the drawer 30 is better, and the user experience is better, and / or, the light source assembly 38 and the pattern 40 of the embodiment of the present application are integrated into the front wall assembly 34, and the structure of the drawer 30 is more compact.

[0082] In some embodiments, the pattern 40 includes an ink layer 41 and a protective layer 43. The ink layer 41 can be illuminated, and the protective layer 43 is transparent. In this way, the protective layer 43 can protect the ink layer 41, the pattern 40 is not easily worn, the ink layer 41 has a better lighting effect when exposed to light, and the decorative effect of the drawer 30 can be more durable. The ink layer 41 can be located between the protective layer 43 and the main body 36.

[0083] In some embodiments, the pattern 40 includes photosensitive color-changing printing ink, and the light source 44 can illuminate the main body 36 to change the color of the pattern 40. In this way, the drawer 30 can have a better atmosphere.

[0084] The photochromic printing ink may include a photochromic or light-activated component, and changes color when illuminated by the light source 44, including, but not limited to, from colorless to colored, from colored to colorless, from light to dark, from dark to light, from translucent to colored, or from one color (e.g., white) to another color (e.g., black), etc. Some photochromic printing inks change color when illuminated by the light source 44, and return to their original state after leaving the light source 44. The photochromic printing ink may be applied to the surface of the main body 36 by printing or the like.

[0085] In some embodiments, the main body 36 includes an inner surface 46 opposite to the visible surface 42, and the pattern 40 is disposed on the inner surface 46. The light source 44 can illuminate the side of the pattern 40 facing the visible surface 42 to light up the pattern 40. In this way, the structure of the drawer 30 can be compact.

[0086] The light source 44 may illuminate the side of the pattern 40 that contacts the main body 36 to light up the pattern 40. The light source 44 may illuminate the main body 36 between the inner surface 46 and the visible surface 42. The inner surface 46, the side of the pattern 40 that does not contact the main body 36, may face the storage space 32. The inner surface 46 may be the rear surface of the main body 36. The visible surface 42 may be located outside the storage space 32 and away from the storage space 32.

[0087] In some embodiments, the light source 44 is disposed adjacent to the periphery of the main body 36. In this way, the light source 44 can be helpful for irradiating the interior of the main body 36 to illuminate the pattern 40, and the structure of the drawer 30 is compact.

[0088] There may be no space between the light source 44 and the periphery of the main body 36. The light source 44 may directly contact the periphery of the main body 36. The main body 36 may be in a substantially square plate shape. The light source 44 may be adjacent to one or more of the peripheral edges of the main body 36, such as the upper edge, the lower edge, the left edge, the right edge, etc.

[0089] In some embodiments, the pattern 40 is stimulated to change color when exposed to light within a specific wavelength range. This can help to create a better atmosphere for the drawer 30. The wavelength of the light irradiating the pattern 40 can correspond to the photochromic or light-activated component of the pattern 40, so that the pattern 40 can be illuminated and stimulated to change color when exposed to light.

[0090] In some embodiments, the pattern 40 includes two or more photosensitive color-changing printing inks, and the light source 44 can illuminate the main body 36 to change the pattern 40 into two or more colors. In this way, the visual effect of the pattern 40 can be enriched, and the atmosphere of the drawer 30 can be better.

[0091] In some embodiments, the main body 36 is transparent and includes at least a partially smooth periphery, which can help illuminate the periphery of the main body 36 and form a bright strip around the periphery of the main body 36 .

[0092] The light-inlet surface 48 may be an outer surface of the main body 36 adjacent to the light source 44. The light-inlet surface 48 may be an outer surface of the periphery of the main body 36. The light-inlet surface 48 may be smooth. After most or all of the light emitted by the light source 44 enters the transparent main body 36 through the smooth light-inlet surface 48, it propagates inside the main body 36 and does not or almost does not leak outside the main body 36.

[0093] In some embodiments, the projection of the light source 44 onto the light-entering surface 48 is located within the light-entering surface 48. In this way, it can help most or even all of the light from the light source 44 to enter the main body 36. The projection area of ​​the light source 44 onto the light-entering surface 48 can be less than or equal to the area of ​​the light-entering surface 48. The projection of the light source 44 onto the light-entering surface 48 can be located in the middle of the light-entering surface 48.

[0094] In some embodiments, the transparency of the pattern 40 is lower than that of the main body 36. In this way, the light from the light source 44 can be transmitted through the main body 36 to illuminate the pattern 40, thereby lighting up the pattern 40. The pattern 40 with low transparency can destroy the total reflection of the light inside the main body 36 with high transparency, and the light can be transmitted through the main body 36 and illuminate the pattern 40, thereby achieving the effect of lighting up the pattern 40. The pattern 40 can be translucent.

[0095] In some embodiments, the front wall assembly 34 includes a side strip 52, wherein the side strip 52 has a lower transparency than the main body 36. This can help reduce or prevent light from the light source 44 from entering the side strip 52 and / or leaking from the side strip 52. The side strip 52 can be translucent or even opaque.

[0096] In some embodiments, the side strip 52 and the main body 36 fix the light source assembly 38 together, so as to facilitate the light source assembly 38 to be firmly positioned.

[0097] In some embodiments, a receiving cavity 54 is defined between the side strip 52 and the main body 36 to receive the light source assembly 38. In this way, the light source assembly 38 can be protected by the side strip 52 and the main body 36 and not easily damaged by the outside world. In addition, the light source assembly 38 can be hidden, and most or even all of it is out of sight.

[0098] The side strip 52 may be constructed at the periphery of the main body 36. The light source assembly 38 may illuminate other peripheries of the main body 36 other than the periphery of the main body 36 where the side strip 52 is located. In some embodiments, the side strip 52 is a decorative piece constructed at the periphery of the main body 36. In this way, the visual effect of the drawer 30 may be better.

[0099] In some embodiments, the side strip 52 is constructed at the upper edge or the lower edge of the main body 36, wherein: the side strip 52 constitutes a handle portion 56 of the drawer 30, and a handle cavity 58 is provided therein, which is overlapped with the receiving cavity 54. In this way, the structure of the drawer 30 can be compact. The drawer 30 can be pulled out by contacting the handle portion 56. Compared with a simple plate-shaped handle portion, the handle portion 56 formed with the handle cavity 58 has a better touch. The handle cavity 58 overlaps with the receiving cavity 54, and the manufacturing cost of the drawer 30 can be lower.

[0100] The visible surface 42 and the inner surface 46 may be smooth planes. Figure 3 for Figure 1 A front view of a light source assembly for a drawer of a household appliance. Figure 3 In an embodiment in which the side strip 52 is constructed at the upper edge of the main body 36, due to the total reflection effect, the light of the light source 44 is confined to the inside of the main body 36, and the lower edge, left edge, and right edge of the pattern 40 and the main body 36 can be illuminated, so as to achieve the projected light effect of highlighting the periphery of the pattern 40 and the main body 36. Similarly, in an embodiment not shown in the figure, the side strip 52 is constructed at the lower edge of the main body 36, and the upper edge, left edge, and right edge of the pattern 40 and the main body 36 can be illuminated, so as to achieve the projected light effect of highlighting the periphery of the pattern 40 and the main body 36.

[0101] In some embodiments, the side strip 52 includes a shielding portion 60 for shielding the light source 44, which partially covers the visible surface 42 from the front. In this way, it is helpful to ensure that the light from the light source 44 enters the main body 36 as much as possible.

[0102] The shielding portion 60 may extend parallel to the visible surface 42. The shielding portion 60 may extend from the handle portion 56 to partially cover the visible surface 42. The shielding portion 60 and the front wall of the handle portion 56 may form the front wall of the side strip 52. The shielding portion 60 may shield the light source 44 from the front. The light of the light source 44 may be blocked by the shielding portion 60 from propagating forward.

[0103] In some embodiments, the side strip 52 includes a first positioning portion 62, and the main body 36 includes a second positioning portion 64 that clamps the light source assembly 38 together with the first positioning portion 62. In this way, the light source assembly 38 can be firmly positioned between the main body 36 and the side strip 52 through the first positioning portion 62 and the second positioning portion 64.

[0104] The side strip 52 and the main body 36 can be assembled by a connection method such as a buckle. In some embodiments, the side strip 52 includes a third positioning portion 66, and the main body 36 includes a fourth positioning portion 68 combined with the third positioning portion 66. In this way, the side strip 52 can be combined with the main body 36 by means of the third positioning portion 66 and the fourth positioning portion 68.

[0105] In some embodiments, the first positioning portion 62 and the second positioning portion 64 position the light source assembly 38 from the vertical direction. In this way, the first positioning portion 62 and the second positioning portion 64 can help ensure the positioning of the light source assembly 38 in the vertical direction.

[0106] In some embodiments, the second positioning portion 64 and the inner surface 46 of the main body 36 position the light source assembly 38 in the front-to-back direction. In this way, the second positioning portion 64 and the inner surface 46 can be used to ensure the positioning of the light source assembly 38 in the front-to-back direction.

[0107] In some embodiments, the first positioning portion 62 extends from the shielding portion 60 into the receiving cavity 54, and the second positioning portion 64 extends from the inner surface 46 to the fourth positioning portion 68. In this way, the light source assembly 38 can be positioned at a position that is not easily visible or affected by the outside world, and the drawer 30 has a more beautiful appearance and a more stable structure.

[0108] The first positioning portion 62 may be a rib extending from the front wall of the side strip 52. The first positioning portion 62 may extend from the front to the back. The first positioning portion 62 may at least partially define the receiving cavity 54 and the handle cavity 58, may be located between the receiving cavity 54 and the handle cavity 58, and may at least partially separate the receiving cavity 54 and the handle cavity 58.

[0109] The second positioning portion 64 may extend partially in parallel with the first positioning portion 62 and partially in parallel with the inner surface 46. The second positioning portion 64 may have a substantially L-shaped cross section. The second positioning portion 64 may be located between the inner surface 46 and the fourth positioning portion 68. The fourth positioning portion 68 may extend rearward from the end of the second positioning portion 64 away from the inner surface 46. The fourth positioning portion 68 may extend parallel to the first positioning portion 62. The end of the fourth positioning portion 68 away from the second positioning portion 64 may be combined with the third positioning portion 66. The fourth positioning portion 68 and the second positioning portion 64 may be close to the periphery of the main body 36.

[0110] The receiving cavity 54 may be located between the first positioning portion 62, the second positioning portion 64, the inner surface 46, and the shielding portion 60. In some embodiments, the light source assembly 38 includes a circuit board 70 on which the light source 44 is mounted and a receiving frame 72 for receiving the circuit board 70, and the receiving frame 72 abuts against the first positioning portion 62, the second positioning portion 64, the inner surface 46, and the shielding portion 60. In this way, it is convenient to control the light source 44 through the circuit board 70, and / or to supply power to the light source 44, and the receiving frame 72 is used to protect the light source 44 and the circuit board 70, thereby reducing the adverse external force and extrusion on the light source 44 and the circuit board 70. The receiving frame 72 may have a roughly C-shaped cross-section. The light emitting portion of the light source 44 may be exposed outward from the notch of the receiving frame 72.

[0111] In some embodiments, the light source 44 is located between the circuit board 70 and the light-incoming surface 48 and between the shielding portion 60 and the containing frame 72. In this way, the light from the light source 44 can be mainly allowed to enter the main body 36 through the light-incoming surface 48. The circuit board 70, the shielding portion 60, and the containing frame 72 can block the propagation of light in corresponding directions. The circuit board 70, the light-incoming surface 48, the shielding portion 60, and the containing frame 72 can be located above, below, front, and rear of the light source 44, respectively.

[0112] In some embodiments, the fourth positioning portion 68 extends from the second positioning portion 64 to the third positioning portion 66. In this way, the structure of the drawer 30 can be more compact. The fourth positioning portion 68 can be located behind the second positioning portion 64. The third positioning portion 66 can be located behind the fourth positioning portion 68. The side strip 52 and the main body 36 can be combined in one or more directions, such as front-to-back and / or up-and-down directions, through the third positioning portion 66 and the fourth positioning portion 68.

[0113] The circuit board 70 with the light source 44 mounted thereon can be inserted into the receiving frame 72 from the notch of the receiving frame 72, so that the light emitting portion of the light source 44 is exposed outward from the notch of the receiving frame 72. The portion of the light source 44 exposed outside the receiving frame 72 is oriented toward the light-incoming surface 48, so that the receiving frame 72 is matched with the inner surface 46 and the second positioning portion 64. The side strip 52 and the main body 36 are brought closer to each other until the first positioning portion 62 abuts against the receiving frame 72 and the third positioning portion 66 is combined with the fourth positioning portion 68, thereby completing the assembly of the front wall assembly 34.

[0114] Figure 4 yes Figure 1 A schematic top view of a light source and circuit board for a drawer of a household appliance. Figure 4 As shown, in some embodiments, the light source 44 includes a first light source 74 and a second light source 76, wherein the pattern 40 is displayed in a first color when the first light source 74 is illuminated, and the pattern 40 is displayed in a second color when the second light source 76 is illuminated. In this way, it can help to enrich the lighting effect of the drawer 30, strengthen the atmosphere, and provide a better user experience.

[0115] There may be a plurality of the first light source 74 and the second light source 76, respectively, arranged along the length direction of the circuit board 70. The first light source 74 and the second light source 76 may be arranged alternately with each other.

[0116] In some embodiments, the first light source 74 and the second light source 76 are light emitting diodes, and the wavelength of the light of the second light source 76 is shorter than that of the first light source 74. In this way, the first light source 74 and the second light source 76 can excite white light, and the color of the pattern 40 can be changed while being lit as needed.

[0117] In some embodiments, the wavelength of the light of the second light source 76 is in the range of 200 nanometers to 420 nanometers, so that the second light source 76 can stimulate the photosensitive color-changing printing ink to change color while stimulating white light, and the display effect of the pattern 40 is better.

[0118] Unless otherwise specified, the numerical values ​​in this application include fluctuations within a certain range. For example, they may fluctuate within a corresponding precision range. For example, 200 may include values ​​within the range of 200x (1 ± 5%), that is, values ​​within the interval of 190 to 210, such as 190, 191, 192, 193, 194, 195 ... 202, 203, 204, 205, 206, 207, 208, 209, 210, and so on.

[0119] Unless otherwise specified, the numerical range in this application includes all arbitrary sub-ranges contained in the range. For example, 200 nanometers to 420 nanometers may include 200 nanometers to 201 nanometers, 200 nanometers to 202 nanometers, 200 nanometers to 203 nanometers, 200 nanometers to 204 nanometers, 200 nanometers to 205 nanometers...250 nanometers to 350 nanometers...419 nanometers to 420 nanometers, and the like.

[0120] Figure 5 This is a partial perspective diagram of a household appliance related to another aspect of the embodiment of the present application. Figure 5 Another aspect of the embodiment of the present application relates to a household appliance 10, which includes a housing 12. The housing 12 can be roughly square. A storage chamber 14 is arranged in the housing 12. The storage chamber 14 can store items such as food, medicine, and beverages (not shown). The household appliance 10 includes a door body 16, which is movably connected to the housing 12 to open and close the storage chamber 14. When the door body 16 is opened, items can be taken from the storage chamber 14. When the door body 16 is closed, the items in the storage chamber 14 can be isolated from the external environment outside the household appliance 10 to reduce the impact of the external environment. The household appliance 10 includes a drawer 30 for the household appliance 10 as described in the present application. The drawer 30 is arranged in the storage chamber 14. In this way, the visual effect of the drawer 30 can be better and the user experience of the household appliance 10 can be better.

[0121] The storage room 14 can be divided into a plurality of compartments. The drawer 30 can be arranged in one or more compartments. The storage room 14 can have a partition 50 adjacent to the drawer 30, which can close the storage space 32 of the drawer 30 from above.

[0122] In some embodiments, the household appliance 10 includes two or more drawers 30 , and the patterns 40 of the multiple drawers 30 present different colors under different environmental conditions. In this way, it is helpful to know the environmental conditions of the multiple drawers 30 by observing the patterns 40 .

[0123] Figure 5 In the illustrated embodiment, the household appliance 10 includes two drawers 30 arranged side by side. In an embodiment not shown, the household appliance 10 may include one or more drawers 30, and the drawers 30 may be arranged side by side, stacked, etc. The pattern 40 of one or more drawers 30 may present corresponding colors according to the environmental conditions thereof.

[0124] Figure 6 FIG. 1 is a flow chart of a control method for a household appliance according to another aspect of an embodiment of the present application. Figure 6 As shown, another aspect of the embodiment of the present application relates to a control method 100 of a household appliance 10 as described in the present application, which includes: step 102, determining whether the environmental parameter in the drawer 30 exceeds a threshold value; and step 104, lighting up the pattern 40 based on the environmental parameter determined in step 102 not exceeding the threshold value, or changing the color of the pattern 40 based on the environmental parameter determined in step 102 exceeding the threshold value. In this way, it is helpful to know whether the environmental parameter in the drawer 30 exceeds the threshold value by observing the pattern 40, so as to decide whether to take corresponding measures or not.

[0125] In some embodiments, the environmental parameter is temperature and / or gas hygiene parameter. Thus, it is helpful to know whether the temperature and / or gas hygiene parameter in the drawer 30 exceeds a threshold value by observing the pattern 40, so as to decide whether to take corresponding measures or not.

[0126] In some embodiments, the control method 100 includes step 106, before step 102, determining whether the door body 16 is in an open state, and executing step 102 based on the door body 16 being in an open state, and not executing step 102 based on the door body 16 being in an unopened state. In this way, it can be beneficial for the household appliance 10 to effectively utilize energy, and reduce and avoid unnecessary power consumption of the drawer 30 when the door body 16 is not opened.

[0127] For example, the household appliance 10 may include a sensor (not shown) for detecting the opening and closing state of the door body 16 and a sensor (not shown) for detecting the temperature in the drawer 30 and / or environmental parameters such as gas hygiene parameters. Based on the detection that the door body 16 is in an open state, the temperature in the drawer 30 and / or environmental parameters such as gas hygiene parameters are detected. Based on the measured temperature in the drawer 30 is not higher than the preset maximum value, not lower than the preset minimum value, and / or the total volatile organic compounds (TVOC) concentration in the gas is not higher than the preset maximum value (such as 500ppb, 3000ppb or other values), it is determined that the environmental parameters in the drawer 30 do not exceed the threshold value, and the first light source 74 is turned on for illumination. The first light source 74 can emit, for example, ordinary white light, and the edge of the main body 36 that is not combined with the side strip 52 and the pattern 40 are lit, and the pattern 40 is displayed as a first color (such as white), and no countermeasures are needed for the temperature and gas in the drawer 30.

[0128] Based on the fact that the temperature in the drawer 30 is higher than a preset maximum value and lower than a preset minimum value, and / or the concentration of total volatile organic compounds (TVOC) in the gas is higher than a preset maximum value, it is determined that the environmental parameters in the drawer 30 exceed the threshold value, and the second light source 74 is turned on for illumination. The second light source 74 can emit, for example, white light with a wavelength in the range of 200 nanometers to 420 nanometers. The edge of the main body 36 that is not combined with the side strip 52 may not have a color change visible to the human eye, but the pattern 40 is switched and displayed as a second color (such as a color other than white), thereby achieving an effect of hiding the change, and the user is prominently reminded through the pattern 40. Temperature adjustment, gas sterilization / deodorization and other treatments can also be automatically or under the instruction of the user.

[0129] Without opening the drawer 30, the environmental parameters inside the drawer 30 can be known by observing the pattern 40. Especially in the case of multiple drawers 30, the environmental parameters inside the drawers 30 can be known without opening each drawer 30 of concern one by one. The environmental parameters are clear at a glance, the user experience is better, and it can help to reduce and avoid the adverse effects caused by unnecessary opening of the drawers 30.

[0130] Please continue to see Figure 1 One aspect of the embodiment of the present application relates to a household appliance 10 ( Figure 5) of a drawer 30. The drawer 30 includes a storage space 32. The drawer 30 includes a front wall assembly 34, which includes a main body 36 that defines the storage space 32 from the front and a light source assembly 38 that can illuminate the main body 36. The drawer 30 includes a side wall 78 that defines the storage space 32 from the side. A receiving portion 80 is provided at a location where the side wall 78 is adjacent to the front wall assembly 34. The drawer 30 includes an electrical connection assembly 82, which includes a wire 84 for providing an electrical connection to the light source assembly 38, and the wire 84 extends from the light source assembly 38, passes through the receiving portion 80 to be connected to a first connection portion 86 located outside the drawer 30.

[0131] The embodiment of the present application can help the drawer 30 used in the household appliance 10 to have a more compact structure, which is convenient for installation, disassembly, cleaning, etc. For example, the wire 84 extends from the light source assembly 38 of the front wall assembly 34, passes through the receiving portion 80 where the side wall 78 and the front wall assembly 34 are adjacent to each other, and is connected to the first connecting portion 86 located outside the drawer 30, and the structure is relatively compact. The first connecting portion 86 connected to the wire 84 is located outside the drawer 30, and the drawer 30 is convenient for installation, disassembly, and cleaning. The receiving portion 80 where the side wall 78 and the front wall assembly 34 are adjacent to receive the wire 84 extending from the light source assembly 38, which can help the wire 84 to be exposed to the field of vision as little as possible, and the appearance of the drawer 30 is more beautiful.

[0132] The side wall 78 may be substantially plate-shaped. The side wall 78 may be a pair of substantially parallel plate walls. The side wall 78 may extend rearwardly behind the front wall assembly 34. The drawer 30 may include a rear wall 79 opposite to the front wall assembly 34 and connecting the two side walls 78, and a bottom wall 81 connecting the front wall assembly 34, the side wall 78, and the rear wall 79 from the bottom. The storage space 32 may be defined between the main body 36, the side wall 78, the rear wall 79, and the bottom wall 81.

[0133] The first connection portion 86 is located outside the receiving portion 80, the storage space 32, and the side wall 78. The first connection portion 86 can be directly connected to the wire 84 from the receiving portion 80 or connected to the wire 84 from the receiving portion 80 through an electrical connector. The first connection portion 86 can be detachably connected to the wire 84 from the receiving portion 80. When the drawer 30 is installed in the household appliance 10, the first connection portion 86 can be connected to the wire 84 from the receiving portion 80. When the drawer 30 is removed from the household appliance 10, the first connection portion 86 can be disconnected from the wire 84 from the receiving portion 80.

[0134] In some embodiments, the main body 36 and the side wall 78 are integrally formed, and a receiving portion 80 is provided at the junction of the main body 36 and the side wall 78, which is open to the rear and spaced from the storage space 32. In this way, the drawer 30 can be made at a lower manufacturing cost and have a more beautiful appearance, and the storage space 32 and / or the items therein have less interaction with the wire 84. The receiving portion 80 is open to the rear, and the wire 84 from the receiving portion 80 can extend backward and be exposed to the sight range as little as possible.

[0135] In some embodiments, the main body 36 and the side wall 78 are assembled together by means of, for example, a snap-fit ​​connection. Figure 7 for Figure 1 Exploded view of a drawer for household appliances. Figure 7 As shown, in some embodiments, the front wall assembly 34 includes side edges 88 extending backward from both sides of the main body 36, and the side edges 88 overlap at least partially with the side walls 78 to form a receiving portion 80. In this way, the receiving portion 80 can be formed at the rear of the main body 36 and the front side of the drawer 30, and the drawer 30 has a better visual effect and is more compact.

[0136] In some embodiments, the front wall assembly 34 includes a side strip 52, which cooperates with the main body 36 to accommodate the light source assembly 38, and at least part of the wire 84 extends from one side of the side strip 52 in the vertical direction in the receiving portion 80 and passes through the receiving portion 80. In this way, the light source assembly 38 can be positioned more stably, and the extension of the wire 84 can be smoother.

[0137] In some embodiments, the receiving portion 80 is provided with an opening 90 that is open to the rear, and one end of the wire 84 is provided with a second connection portion 92 that is connected to the first connection portion 86, and the second connection portion 92 is adjacent to the opening 90. In this way, the wire 84 can be extended backward through the opening 90, and the first connection portion 86 and the second connection portion 92 can be connected and separated to establish and disconnect the electrical connection when installing and disassembling the drawer 30, so as to prevent the wire 84 from being exposed too much after passing through the receiving portion 80. One or both of the first connection portion 86 and the second connection portion 92 can be the end of the wire 84 or an electrical connector connected to the wire 84.

[0138] In some embodiments, the side wall 78 includes an overlapping portion 94 extending toward the main body 36 and overlapping the side edge 88, and the receiving portion 80 is defined between the overlapping portion 94 and the side edge 88, wherein a matching portion 96 fixedly connected to the side edge 88 is formed on the overlapping portion 94. In this way, the side wall 78 and the main body 36 formed separately can be fixedly connected to form the receiving portion 80 to receive at least part of the wire 84, the extension of the wire 84 is relatively smooth, and the structure of the drawer 30 is compact. There can be one or more matching portions 96. The side edge 88 can have a fixed connection structure 99 corresponding to the matching portion 96.

[0139] Figure 8 yes Figure 7 Partial exploded view of a drawer for household appliances. Figure 8 In some embodiments, the overlapping portion 94 is provided with a wiring structure 98 for guiding the wire 84 .

[0140] In some embodiments, the overlapping portion 94 includes a first wall 31 formed at the front end of the side wall 78 and a second wall 33 disposed opposite to the first wall 31 in the front-to-back direction, and the opening 90 is a notch formed in the second wall 33. In this way, the wire 84 can be extended between the first wall 31 and the second wall 33 and pass through the second wall 33 at the rear.

[0141] In some embodiments, the wiring structure 98 includes a wire groove 35 located at the top or bottom of the overlap portion 94. In this way, it can be helpful for the wire 84 to pass through the top or bottom of the overlap portion 94 through the wire groove 35.

[0142] In some embodiments, the wiring structure 98 and the matching portion 96 are arranged in a staggered manner, so that the mutual influence between the wiring structure 98, the wire 84 and the matching portion 96 is small.

[0143] In some embodiments, the side edge 88 is non-transparent and covers the outside of the overlap portion 94. In this way, the structure inside the side edge 88 can be invisible, and the appearance of the drawer 30 is beautiful.

[0144] Fig. 9 and Figure 8 Similar, but from a different perspective. Figure 4 , 9 As shown, in some embodiments, the light source assembly 38 includes a light source 44 and a circuit board 70 on which the light source 44 is mounted, wherein the circuit board 70 extends along the side edge 88 and / or the side strip 52. In this way, it is convenient to control the light source 44 and / or power the light source 44 through the circuit board 70, and the light source 44 illuminates the main body 36 along the side edge 88 and / or the side strip 52. The wire 84 can be connected to the end of the circuit board 70 and extend from the end of the circuit board 70.

[0145] In some embodiments, the main body 36 is transparent, and the light source assembly 38 illuminates the interior of the main body 36 to light up the pattern 40 provided on the main body 36. In this way, it can help the light to mainly propagate inside the main body, and the decorative effect is rich and the atmosphere is strong.

[0146] In some embodiments, the light source assembly 38 is disposed adjacent to the periphery of the main body 36. In this way, it is advantageous for the light source assembly 38 to illuminate the main body 36 from the periphery of the main body 36.

[0147] In some embodiments, the light source assembly 38 includes two or more light emitting diodes with different light wavelengths, wherein the light wavelength of at least one light emitting diode is in the range of 200 nanometers to 420 nanometers. In this way, the light source assembly 38 can be helped to excite white light, and at the same time, excite at least one photosensitive color-changing printing ink.

[0148] In some embodiments, the pattern 40 includes photosensitive color-changing printing ink, and the light source 44 can illuminate the main body 36 to change the color of the pattern 40. In this way, the drawer 30 can have a rich decorative effect and a strong atmosphere.

[0149] In some embodiments, the main body 36 includes a smooth light-entering surface 48, and the projection of the light source 44 onto the light-entering surface 48 is located within the light-entering surface 48. In this way, it is possible to facilitate the light emitted by the light source 44 to directly and more enter the main body 36 through the light-entering surface 48 and propagate inside the main body 36.

[0150] In some embodiments, the electrical connection assembly 82 includes a motion protection portion 37 that moves with the drawer 30, and the wire 84 extends from the first connection portion 86 to the motion protection portion 37.
