[0073] In order to make the technical problems, technical solutions and beneficial technical effects to be solved by the present invention more clearly understood, the present invention will be further described in detail in conjunction with the accompanying drawings and multiple exemplary embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the scope of protection of the present invention, and each embodiment may share the same view or multiple views for description, but all features appearing in the same view cannot be interpreted as features that must be possessed by an embodiment, and multiple views cannot be simply combined and interpreted for one embodiment.

[0074] First, for ease of understanding, you can look back or recall the description made in the background technology part of the present invention. The purpose of the present invention is to provide a household appliance, which has a lamp assembly that is easy to install, especially a lamp assembly that is also very simple in structure and manufacture, and the lamp assembly is especially arranged on the outside of the household appliance and emits light outward. Arranged on the outside of the household appliance mainly plays the role of indicating the working status and / or improving the quality. The lamp assembly can be used as a handle light of a household appliance, especially a wall washer at the handle. Before starting the formal description, it should be pointed out that, for the sake of convenience, this article may use directional terms or directional terms for description. The directional terms or directional terms are relative to the normal use state of the household appliance (especially the refrigerator). Those skilled in the art can also clarify this from the description of the present invention without causing any confusion. In this case, the directional terms and directional terms should not be simply interpreted as the orientation or direction in any state.

[0075] Moreover, the ordinal numbers such as "first" and "second" in this specification are provided to avoid confusion among constituent elements, rather than to limit the quantity, nor do they mean that there is any difference in importance between them.

[0076] It must also be pointed out that due to the proportional relationship, the limitation of the space of the figure markings, etc., in the following description, it may be necessary to refer to multiple figures at the same time for understanding.

[0077] Figure 1 A possible application scenario of the lamp assembly of the present invention when used in a refrigerator is shown. Figure 2 Shows Figure 1A three-dimensional view of a refrigerator door is shown to better illustrate the use scenario of the light assembly of the present invention as a handle light on a refrigerator. Figure 3 The lamp assembly according to an exemplary embodiment of the present invention is shown as being mounted on a door handle along the Figure 2 Sectional view made along the cutting line DD. Figure 4 Shown separately Figure 3 A cross-sectional view of the lamp assembly is shown.

[0078] First, see Figure 1-Figure 4 As for the lamp assembly, according to one aspect of the present invention, there is provided a lamp assembly for a household appliance 1, in particular a handle lamp 2, the lamp assembly comprising: a light source assembly 21, which comprises a light emitting element 211; and a lamp frame 22. The lamp frame 22 comprises: a light emitting wall 221 for emitting light and an enclosure portion 223 which, together with the light emitting wall 221, encloses a cavity 222 for accommodating the light source assembly 21, wherein the enclosure portion 223 is configured to allow the lamp frame 22 to be detachably embedded and retained in the receiving groove 11 of the household appliance 1 as a whole without generating a structural bite action with the receiving groove 11 in the opposite direction A of the depth direction of the receiving groove 11 when the lamp assembly is embedded. The lamp frame 22 may also constitute a part of the housing or lampshade of the lamp assembly. The light emitting wall 211 itself also constitutes a part of the housing or lampshade of the lamp assembly.

[0079] Accordingly, according to another aspect of the present invention, a household appliance 1 is provided, which includes the lamp assembly and a receiving groove 11 for accommodating the lamp assembly, wherein the receiving groove 11 has an inlet for receiving the lamp assembly.

[0080] Here, it should be made clear that, especially with respect to the lamp frame 22 and the receiving groove 11, the lamp frame 22 can be retained in the receiving groove 11 by the lateral embedding of the entrance, wherein the term "lateral" refers to both the outward irradiation direction of the light of the lamp assembly and the structural shape of the lamp assembly itself. In the case of the present invention, lateral can be understood as the side away from the irradiation direction of the light, that is, away from the light outlet wall 221. The lamp assembly is laterally embedded and located in the receiving groove 11, exposing the light outlet wall 221. This can be better understood when the lamp assembly is in a strip shape.

[0081] "Embedded" means embedded in the receiving groove 11. "Integrally detachable" means that the lamp frame 22 can be embedded in the receiving groove 11 as a whole, without any structural separation of the lamp frame 22 before and / or during embedding into the receiving groove 11. Moreover, if there is no other retaining or positioning structure, the lamp frame 22 can be separated from the receiving groove 11 as a whole again in the direction opposite to the depth direction A after embedding, especially without using any special tools or special materials, because the lamp frame 22 does not have a structural bite effect with the receiving groove 11 in the opposite direction of the depth direction A in the embedded state. "Structural bite effect" means that there is a shape lock or snap and / or there are other mechanical fastening methods, such as screws and / or material bonding methods, such as bonding. Since the lamp frame 22 does not have a structural bite effect in the opposite direction of the depth direction A, it can be easily removed from the receiving groove 11 in the opposite direction of the depth direction A in the case of removing other possible retaining structures or positioning structures, which is very advantageous. This embedding method of the present invention can particularly refer to a close fit or interference fit. In particular, in the case of lateral embedding, there is no latching connection between the corresponding outer side of the lamp frame 22 and the receiving groove 11 that prevents the lamp frame 22 from being disassembled in the direction opposite to the depth direction A. More particularly, there are no protruding claws on the outer side of the lamp frame 22 and / or the inner side of the receiving groove 11. For example, the lamp frame 22 can be located in the receiving groove 11 in a tensioned and clamped manner.

[0082] Preferably, the lamp frame 22 is held in the receiving groove 11 in a multi-faceted manner.

[0083] "Maintain" means that the light frame 22 can be stably positioned in the receiving groove 11 to achieve the desired positioning effect. Of course, this does not exclude the existence of other positioning measures. For example, the light frame 22 can also be pressed against the light frame 22 along the depth direction A from the side of the light outlet wall 221 using an external structure to limit the light frame 22 in the receiving groove 11 in the depth direction A, which further ensures that the light frame 22 will not escape from the receiving groove 11. In addition, the light assembly can also be positioned from the end of the light assembly, for example. The following will be described in conjunction with specific exemplary embodiments. However, no matter what the positioning method is, it does not rely on the locking, screw fixing and bonding between the light frame 22 and the corresponding structure. On the contrary, it relies on the enclosure or maintenance of the position of the light frame 22 by the surrounding structure. In particular, the light assembly is simply located in the space enclosed by the surrounding structure in the assembled state, and there is no structural bite effect, especially no locking, screw connection or bonding relationship with the surrounding structure.

[0084] This positioning method is closely related to the structure, manufacturing and installation of the lamp assembly of the present invention, making the related process simple and efficient, which can be clearly seen from the following description.

[0085] In addition, those skilled in the art can also understand that the “light emitting wall” refers to the area on the light frame 22 where light is expected to be emitted outwardly, rather than any area that can transmit even a little light in a strict sense.

[0086] It is also necessary to point out that the final installation process of the lamp assembly of the present invention cannot be simply equivalent to or directly or indirectly define the possible matching relationship between the two components. In other words, describing the matching relationship between the two components does not directly imply the corresponding installation process. For example, the lamp assembly may be embedded sideways or inserted up and down, but it does not affect the engagement (matching) relationship between the lamp assembly and the receiving slot 11.

[0087] According to an exemplary embodiment of the present invention, Figure 3 and Figure 4 As shown, the light source assembly 21 is arranged spaced apart from the light exit wall 221. Here, the space between them is filled with air, and the light emitting element 211 of the light source assembly 21 directly irradiates toward the light exit wall 221. This is different from the light emitted by the light emitting element 211 being transmitted to the light exit wall 221 through a physical light transmission structure.

[0088] like Figure 3 and Figure 4 As shown, the lamp frame 22 is closed in the circumference. Here, "circumferentially" is relative to Figure 3 and Figure 4 In terms of cross section.

[0089] According to an exemplary embodiment of the present invention, Figure 3 and Figure 4 As shown, the enclosure portion 223 includes a first side wall 2231 and a second side wall 2232 arranged opposite to each other, and at least in the embedding area B engaged with the receiving groove 11, the distance C between the outer side of the first side wall 2231 and the outer side of the second side wall 2232 decreases or remains unchanged in the depth direction A. This is obviously technically consistent with the above-mentioned integral embedding method of the lamp frame 22.

[0090] Figure 5 Similar to Figure 4 1 is a cross-sectional view of a lamp assembly according to another exemplary embodiment of the present invention.

[0091] Figure 6 Similar to Figure 3 The way it is shown Figure 5 A cutaway view of the lamp assembly shown installed on a door handle.

[0092] Figure 5 , Figure 6 The basic structure of the lamp assembly shown in Figure 3 , Figure 4 The basic structure of the lamp assembly shown in FIG. 1 is different. For example, Figure 5 and Figure 6 As shown, the distance C between the outer side of the first side wall 2231 and the outer side of the second side wall 2232 decreases at least once in a stepwise manner in the depth direction A. In other words, there is at least a step structure on the outer side of the first side wall 2231 and / or the second side wall 2232 .

[0093] exist Figure 6 In an exemplary embodiment, the receiving groove 11 is formed in a door handle 13 which can be a separate component and has a bottom wall 111, a front wall 113 connected to the bottom wall 111 and close to the front end 112 of the door outer panel 18 of the door body, and a rear wall 115 connected to the bottom wall 111 and away from the rear end 114 of the door outer panel 18.

[0094] from Figure 6 As can be seen in the figure, according to an exemplary embodiment of the present invention, the front surface of the front wall 113 may be adjacent to the rear surface of the door outer panel 18, and even a partial area therebetween may be in direct contact with each other.

[0095] According to an exemplary embodiment of the present invention, the gap between the front surface of the front wall 113 and the rear surface of the door outer panel 18 is smaller than the wall thickness of the front wall 113 itself.

[0096] According to an exemplary embodiment of the present invention, the front surface of the front wall 113 is parallel to the door outer panel 18 .

[0097] According to an exemplary embodiment of the present invention, the door handle includes a grip wall 116 connected to the front wall 113 to form at least a portion of a grip portion of the door handle, and a front surface of the grip portion is substantially coplanar with a front surface of the front wall 113 .

[0098] When the lamp assembly of the present invention is used as a handle lamp and is to be embedded in the handle area of ​​the door body, the available space is very small, so the cross-sectional size of the lamp assembly is also very small, and a cavity is formed inside the lamp assembly, which makes the wall of the lamp assembly thinner and the overall strength is not high. In particular, as a handle lamp, the length is large and the strength problem is more prominent. At this time, the step structure on the first side wall 2231 and / or the second side wall 2232 can play the role of a reinforcing rib, thereby improving the overall strength of the lamp assembly.

[0099] Moreover, from Figure 5 and Figure 6 It can be seen that the step structure can make the area where the light source assembly 21 is located smaller, and the size (i.e., width) of the light source assembly 21 can also be designed to be smaller so that it can be kept on the lamp frame 22, which is very beneficial to reducing costs. In particular, when the light source assembly 21 adopts a printed circuit board, the size of the printed circuit board can be significantly reduced, which is very beneficial. The size of the printed circuit board directly affects the cost of the light source assembly 21.

[0100] According to an exemplary embodiment of the present invention, in particular Figure 5 and Figure 6 As shown, the width of the light source assembly 21 is smaller than the width of the light exit wall 221. This size relationship can be easily achieved by the above-mentioned step structure.

[0101] According to an exemplary embodiment of the present invention, Figure 3-Figure 6 As shown, the lamp frame 22 further includes a flange 224 protruding outward from the light outlet wall 221 on the side of the first side wall 2231. The flange 224 can fit with the corresponding opening edge of the receiving groove 11 to achieve a smooth transition.

[0102] like Figure 5 and Figure 6 As shown, the opening edge area of ​​the receiving groove 11 can also be provided with a corresponding recess to receive the flange 224, but no structural bite effect opposite to the depth direction A will be generated.

[0103] like Figure 3-Figure 6 As shown, the lamp frame 22 further includes an extension structure 225 extending outward from the light outlet wall 221 on the side of the second side wall 2232. The extension structure 225 is located on the opposite side of the flange 224. The lamp frame 22 can be more reliably held in the receiving groove 11 by a corresponding limiting structure that blocks the extension structure 225 from the outside. As an example, the limiting structure can be a component of a wall washer system, which will be described in more detail below.

[0104] Preferably, the limiting structure abuts against the outer side of the lamp assembly over at least most of the length of the handle buckle groove 131, preferably the entire length or more than 90% of the entire length. This can better keep the lamp assembly in the receiving groove 11 over the entire length and ensure the straightness of the lamp assembly.

[0105] Preferably, the blocking structure acts on the edge of the housing from the light emitting side of the lamp assembly between the two ends of the lamp assembly to block the lamp assembly. Figure 3-Figure 6 As shown, the enclosure portion 223 also includes a rear wall 2233 arranged opposite to the light outlet wall 221 and connecting the first side wall 2231 and the second side wall 2232, and the light source assembly 21 is spaced apart from the rear wall 2233. The space between the light source assembly 21 and the rear wall 2233 is also filled with air only, so the heat generated by the light source assembly 21 can be dissipated from both sides. The rear wall 2233 is preferably fitted with the corresponding area in the receiving groove 11, that is, the bottom area. The rear wall 2233 of the lamp frame 22 fits with the bottom of the receiving groove 11, which can achieve better positioning of the lamp frame 22 in the receiving groove 11.

[0106] Preferably, most of the enclosing portion 223 , especially more than 90%, fits with the receiving groove 11 .

[0107] In order to reliably hold the light source assembly 21 in the lamp frame 22, the lamp frame 22 further includes a holding structure for holding the light source assembly 21. In this embodiment, the light source assembly 22 is held by means of the structure of the lamp frame 22 itself, which can further simplify the structural design of the lamp assembly.

[0108] According to an exemplary embodiment of the present invention, Figure 3-Figure 6 As shown, the holding structure includes a first holding groove 2261 for holding one side edge of the light source assembly 21 and a second holding groove 2262 for holding the other side edge of the light source assembly 21, wherein the first holding groove 2261 is formed on the first side wall 2231, and the second holding groove 2262 is formed on the second side wall 2232 (see Figure 5 ) or formed on the support structure 227 arranged near the second side wall 2232 (see Figure 4 The support structure 227 is located inside the lamp frame 22 and may be a part of the lamp frame 22 .

[0109] Furthermore, if Figure 3-Figure 6 As shown, the first retaining groove 2261 is defined by two first bosses 2263 protruding from the inner side of the first side wall 2231. Similarly, the second retaining groove 2262 is defined by two first bosses 2263 protruding from the inner side of the second side wall 2232 (see Figure 5 ) or support structure 227 (see Figure 4 ) is defined by two second bosses 2264 protruding from one side of the light source assembly 21.

[0110] Similar to the above-mentioned step structure, the above-mentioned boss can also serve as a reinforcing rib.

[0111] According to an exemplary embodiment of the present invention, Figure 3 and Figure 4 As shown, the support structure 227 is preferably integrally formed to extend from the light outlet wall 221 to the rear wall 2233. This connection can enhance the strength of the entire lamp frame.

[0112] According to an exemplary embodiment of the present invention, the rear wall 2233 is at least partially arranged parallel to the light exit wall 221. Figure 3-Figure 4 In the exemplary embodiment shown, the extension structure 225 is parallel to the corresponding portion of the rear wall 2233, but the portion of the rear wall 2233 is not parallel to the light exit wall 221, nor is it in the same plane as the rest of the rear wall 2233. The extension structure 225 is tilted forward (in the direction of light irradiation) relative to the light exit wall 221. Similarly, the portion of the rear wall 2233 corresponding to the extension structure 225 is also tilted forward relative to the rest of the rear wall 2233. This forward tilt is relevant to the application scenario of the handle light.

[0113] like Figure 3-Figure 6 As shown, the light exit wall 221 , the first side wall 2231 , the second side wall 2232 and the rear wall 2233 are integrally formed.

[0114] It has been mentioned above that the outer side of the first side wall 2231 and / or the second side wall 2232 also has a step structure, but it may be preferred that the first side wall 2231 has a first step structure 2234 at the first retaining groove 2261. Similarly, the second side wall 2232 (see Figure 5 ) or support structure 227 (see Figure 4 ) has a second step structure 2235 at the second retaining groove 2262.

[0115] According to an exemplary embodiment of the present invention, Figure 3 and Figure 4 As shown, a circumferentially closed cavity 228 is formed between the support structure 227 and the second side wall 2232. The circumferential closure of the cavity 228 is also aided by the expansion structure 225 and a portion of the rear wall 2233. When the lamp assembly of the present invention is used as a wall washer at a door handle, the provision of the cavity 228 can reduce the size of the light source assembly 21 on the one hand, and can also raise the projection height and angle of the light emitting element 211 relative to the projection surface on the other hand.

[0116] The above has been described in detail with reference to the accompanying drawings and specific embodiments of the lamp assembly of the present invention. However, before further description, it is necessary to Figure 1 and Figure 2 Possible application scenarios of the lamp assembly of the present invention are described.

[0117] With the development of technology and the improvement of people's pursuit of quality of household appliances, in addition to the requirements for the basic performance of household appliances, the user experience is also an important aspect that people consider. More and more household appliances are equipped with lights that emit light outward on the outside. These lights are used to improve the user experience or to indicate or inform users of the possible working status or other information of the household appliances. For household appliances, they are usually equipped with doors, and door handles are usually provided on the doors to facilitate users to operate the doors. The door handle area is usually an area that users pay more attention to.

[0118] Door handles come in a variety of forms. For example, refrigerator door handles usually come in a pull handle form and a buckle handle form. The pull handle protrudes from the outer panel of the refrigerator door, while the buckle handle is usually set at the edge of the refrigerator door frame or directly uses the door frame structure and does not protrude from the outer panel of the refrigerator door. The buckle handle can make the outer surface of the refrigerator door flat, which provides the possibility of various novel and attractive designs for the outer surface of the refrigerator door. For example, the outer panel of the refrigerator door can be made of a whole piece of glass, which greatly improves the quality of the refrigerator.

[0119] Moreover, as people's living standards continue to improve, high-quality or large refrigerators have begun to enter thousands of households. Figure 1 As shown, the door handle 13 of the side-by-side refrigerator is generally arranged at the vertical edge of the door frame of the refrigerator. Due to the limited space between the two side-by-side doors, the door handle 13 at the vertical door frame of at least one of the doors usually has a notch 132 on the front side (see also FIG. Figure 2 ), so that the user's finger can be buckled into the handle buckle groove 131 through the notch 132 (see also Figure 2 , Figure 3 and Figure 6 ). For example, in Figure 1 In the embodiment, the door handle 13 at the door frame of the left door of the refrigerator is a door handle with a notch 132.

[0120] The presence of the notch 132 allows the side surface 1312 (the inner side surface located inwardly, see FIG. 131 ) of the handle buckle groove 131 to face the front side. Figure 3 and Figure 6 ) is exposed, and this exposure makes it possible to consider arranging a lamp assembly at the handle buckle groove 131, so that the lamp assembly illuminates the exposed area or directly arranges the lamp assembly in this area. In particular, if a lamp assembly is arranged at the bottom 1311 of the handle buckle groove 131 of the door handle 13, and illuminates obliquely toward the side 1312 serving as the projection surface, this will produce an optical effect of wall washing illumination on the side 1312. This wall washing effect will greatly improve the quality of the refrigerator and also provide the possibility of visual indication of the working status of the refrigerator. Those skilled in the art will also understand that although the side 1312 is described here as a part of the handle buckle groove 131, in a broad sense it can also be an adjacent area outside the handle buckle groove 131, that is, an area to be irradiated adjacent to the handle buckle groove 131. At this time, the area to be irradiated is exposed to the front of the household appliance, and therefore it can also be called a visible area.

[0121] like Figure 3 As shown, the receiving groove 11 is open toward the handle buckle groove 131. The handle buckle groove 131 has a portion that is gripped by the user's fingers when the user opens the door body, that is, a gripping portion.

[0122] In order to produce a better wall-washing effect, preferably, the optical axis of the light-emitting element 211 intersects the visible area directly behind the grip portion. The "optical axis" here refers to the main light-emitting direction of the light-emitting element 211. With this arrangement, the area with the highest brightness projected by the light-emitting element 211 on the visible area is hidden directly behind the grip portion.

[0123] This also means that the light assembly is configured relative to the visible area so that the brightness of the visible area gradually decreases along the direction away from the handle buckle groove 131.

[0124] Also for the purpose of achieving a better wall washing effect, according to an exemplary embodiment of the present invention, the angle between the optical axis of the light emitting element 211 and the plane where the visible area is located is between 20 degrees and 30 degrees.

[0125] In addition, according to an exemplary embodiment of the present invention, the distance between the light emitting element 211 and the far end of the visible area away from the handle buckle groove 131 is between 70 mm and 90 mm.

[0126] Furthermore, according to an exemplary embodiment of the present invention, the vertical distance between the light emitting element 211 and the visible area is between 15 mm and 25 mm.

[0127] Especially from Figure 3 It can be seen that the second side wall 2232 and the first side wall 2231 are closer to the visible area.

[0128] According to an exemplary embodiment of the present invention, Figure 3 and Figure 4 As shown, the distance between the end face of one side of the second side wall 2232 away from the light exit wall 221 (i.e., the end face close to the bottom of the receiving groove 11) and the center plane of the light source assembly 21 (i.e., the center plane of the light source assembly 21 in the width direction) is greater than the distance between the end face of one side of the first side wall 2231 away from the light exit wall 221 and the center plane of the light source assembly 21. This means that the light emitting element 211 is arranged in the lamp frame 22 to be more convenient for oblique illumination toward the visible surface, especially with a higher oblique illumination height.

[0129] like Figure 5 and Figure 6 As shown, according to an exemplary embodiment of the present invention, the angle between at least a portion of the second side wall 2232 and the front surface of the door body is greater than the angle between the corresponding portion of the first side wall 2231 disposed on the opposite side of the optical axis of the light emitting element 211 and the front surface of the door body. Figure 5 and Figure 6In the illustrated embodiment, this is the case with the inclined portion at the step of the second side wall 2232 and the corresponding step portion on the first side wall 2231. This means that the lamp assembly can be arranged at a greater inclined angle relative to the viewing area.

[0130] According to an exemplary embodiment of the present invention, the distance between the light emitting element 211 and the inner surface of the door outer panel 18 is between 10 mm and 15 mm, so that the light emitting element 211 can be indirectly limited to have a certain inclination angle relative to the visible area.

[0131] like Figure 2 As shown, the handle buckle groove 131 is formed on a relatively long length of the door frame of the refrigerator, so according to an exemplary embodiment of the present invention, the light assembly can be in a strip shape and arranged along the entire length of the door handle. In this way, a light strip can be formed on the projection surface.

[0132] Figure 7 An exemplary embodiment of the present invention is shown. Figure 2 The door body of the present invention presents a wall-washing illumination effect when the handle lamp is in operation. It can be seen that a vertical continuous light band 20 is formed on the projection surface. The light band 20 extends from the inside to the outside of the projection surface, that is, Figure 7 A decreasing wall-washing effect is shown from left to right in the figure.

[0133] See also Figure 3 and Figure 6 , those skilled in the art can understand that in order to achieve a good wall-washing illumination effect, the light-emitting element 211 has a certain height and angle relative to the projection surface. Figure 3-Figure 6 As shown, according to an exemplary embodiment of the present invention, the light emitting element 211 is arranged between the first side wall 2231 and the second side wall 2232, closer to the first side wall 2231. More specifically, the light emitting element 211 is arranged adjacent to the first side wall 2231. At this time, relative to the second side wall 2232, the first side wall 2231 is arranged farther away from the projection surface.

[0134] It can be seen that the offset arrangement of the light emitting element 211 in the lamp frame 22 is very beneficial for the wall washer lamp.

[0135] According to an exemplary embodiment of the present invention, Figure 3 and Figure 6As shown, in order to further improve the wall washing effect of the lamp assembly of the present invention that is slanted toward the side 1312 of the handle buckle groove 131, it can be considered to lay a decorative panel 15 on the side 1312 so that the lamp assembly is slanted toward the outer surface 151 of the decorative panel 15, and the edge 152 of the decorative panel 15 can limit the extended structure 225 of the lamp frame 22. At this time, the decorative panel 15 plays a role in achieving a better optical wall washing effect on the one hand, and on the other hand, it also plays a role in pressing the lamp frame 22 from one side of the light outlet wall 221, so that the lamp assembly can be more reliably kept in the receiving groove 11. It can be seen from this that the decorative panel 15 extends to the visible area and at least serves as a part of the visible area.

[0136] After the lamp frame 22 is embedded in the receiving groove 11, the decorative panel 15 can be fixed to the side surface 1312, so that the lamp frame 22 can be restricted from being separated from the receiving groove 11 in the opposite direction of the depth direction A. When disassembling, the decorative panel 15 can be removed first, and then the lamp frame 22 can be taken out. It should be pointed out that the removal of the lamp frame 22 also depends on the absence of restrictions from other structures.

[0137] exist Figure 3 and Figure 6 In the exemplary embodiment shown, the edge 152 of the decorative panel 15 presses against the expansion structure 225. Figure 6 In the exemplary embodiment shown, the expansion structure 225 is a sheet-like structure that protrudes outward relative to the second side wall 2232, which can be clamped between the edge 152 of the decorative panel 15 and the corresponding portion of the receiving groove 11 (for example, at Figure 6 In the middle, between the opening edge of the inner side of the receiving groove 11).

[0138] According to an exemplary embodiment of the present invention, the decorative panel 15 can be glass, metal, ceramic, wood or any combination thereof. Of course, those skilled in the art can also understand that the present invention is not limited to this, and even special materials can be customized according to user requirements.

[0139] like Figure 3 and Figure 6 As shown, the decorative panel 15 is configured in a plate shape, and its upper surface 151 is a plane.

[0140] When the decorative panel 15 is a glass plate, the front surface may be frosted and the rear surface may have an opaque layer.

[0141] According to an exemplary embodiment of the present invention, the decorative panel 15 is fixed to the side surface 1312 by bonding.

[0142] Furthermore, according to an exemplary embodiment of the present invention, Figure 3As shown, the first side wall 2231 and the second side wall 2232 are in a trumpet shape relative to each other at least in the corresponding sections between the light exit wall 221 and the light emitting element 211. This shape can reflect part of the light emitted from the light emitting element 211 and then project it onto the projection surface, which is beneficial to the formation of the wall washing effect and can also efficiently utilize the light.

[0143] Next, let's look at the structure of the door handle 13.

[0144] According to an exemplary embodiment of the present invention, the door handle 13 is configured as an integrally formed aluminum alloy handle. Figure 6 In the exemplary embodiment shown, the aluminum alloy handle is formed with a receiving groove 11 having a W-shaped structure for matching with the lamp frame 22. The W-shaped structure is Figure 6 The W-shaped structure is located at the lower right area of ​​the receiving groove 11. This W-shaped structure is suitable for installing and positioning the lamp assembly.

[0145] At this time, the door handle 13 can have the same cross section. The handle light 2 is embedded in the handle buckle groove 131 of the door handle 13. The handle light 2 can be installed on the door body of the refrigerator compartment of the refrigerator.

[0146] like Figure 3 and Figure 6 As shown, the door handle 13 is sealed with the outer door panel 18 of the refrigerator and is sealed with other components, such as the inner liner of the door body, to form an inner cavity that can be filled with a heat-insulating foam material. At least part of the side of the door handle 13 that is away from the handle buckle groove 131 is in direct contact with the foam material.

[0147] In the present invention, the handle light 2 is embedded in the handle buckle groove 131 of the door handle 13 and does not involve direct contact with the foam material.

[0148] Those skilled in the art will appreciate that the handle buckle groove 131 can be configured according to the cross-sectional shape of the handle lamp 2. Figure 5 and Figure 6 Compared to the exemplary embodiment shown, Figure 3 and Figure 4 The handle lamp 2 in the exemplary embodiment shown is arranged relatively inward, which affects the height and angle of the light-emitting element 211 relative to the projection surface. At this time, the minimum distance between the side of the handle buckle groove 131 facing the door outer panel 18 and the door outer panel 18 at the groove bottom 1311 area is E, and the minimum distance E allows the foaming material to flow through and wrap the groove bottom 1311 area. This does not affect the heat insulation effect of the door body here.

[0149] And for Figure 5 and Figure 6In the exemplary embodiment shown, the minimum distance E is almost zero. The foam material cannot enter the area between the outer side of the groove bottom 1311 and the door outer panel 18, but in practice it is found that it does not have much impact on the insulation effect, but makes the light-emitting element 211 of the handle lamp 2 have a larger distance and tilt angle relative to the projection surface.

[0150] Moreover, for Figure 5 and Figure 6 In the exemplary embodiment shown, the door handle 13 includes a sinking area 16 at the side 1312 adjacent to the groove bottom 1311 for facilitating the removal and installation of the handle lamp 2. In the installed state, the sinking area 16 is at least partially covered by the decorative panel 15. The sinking area 16 can be a substantially triangular cross section.

[0151] Due to the presence of the sinking area 16 , the sheet-like expansion structure 225 can be attached to one side (corner) of the sinking area 16 , so that it can be clamped between the edge 152 of the decorative panel 15 and the side.

[0152] When disassembling, the decorative panel 15 can be removed first, and then the handle lamp 2 can be pulled toward the sinking area 16, and the handle lamp 2 can fall into the sinking area 16, and then the handle lamp 2 can be taken out. Those skilled in the art can understand that the sinking area 16 also facilitates the embedding of the handle lamp 2. No further details will be given here.

[0153] like Figure 1 , Figure 2 and Figure 7 As shown, the door handle 13 is not a door handle 13 that passes through from top to bottom, but is only located on a section of the vertical frame of the door body. To this end, according to an exemplary embodiment of the present invention, as Figure 1 As shown, the household appliance 1 further comprises at least one closing structure 14 closing the end of the handle buckle groove 131. The closing structure 14 can also be used to support and hold the corresponding end of the handle lamp 2.

[0154] According to an exemplary embodiment of the present invention, the enclosing structure 14 is configured to limit the end of the lamp assembly in a manner of enclosure without generating a structural bite effect with the end of the lamp assembly at least in the longitudinal direction of the end of the lamp assembly away from the enclosing structure 14. Here, the "longitudinal direction" is perpendicular to the aforementioned "lateral direction" and "depth direction A".

[0155] This means that the end of the handle lamp 2 can be longitudinally inserted into the corresponding position of the closure structure 14 and can be easily pulled out from it in the reverse direction. This is similar to the sideways embedding of the lamp frame 22 into the receiving groove 11.

[0156] Figure 8 FIG. 1 shows a perspective view of the enclosed structure 14 according to an exemplary embodiment of the present invention. Figure 8As shown, a retaining groove 12 for receiving the end of the handle light 2 is provided on one side of the closed structure 14 facing the end of the handle light 2. The retaining groove 12 can enclose the end of the handle light 2 without generating a structural bite effect at least in the longitudinal direction of the end of the handle light 2 away from the retaining groove 12 (that is, the direction in which the end of the handle light 2 is pulled out of the retaining groove 12). However, the retaining groove 12 can limit the end of the handle light 2 from sliding laterally out of the retaining groove 12, thereby limiting the handle light 2 from detaching laterally from the receiving groove 11.

[0157] Preferably, the side wall of the retaining groove 12 facing the handle buckle groove 131 is detachable, which can facilitate the disassembly and assembly of the lamp assembly.

[0158] like Figure 1 , Figure 2 and Figure 7 As shown, the door handle is arranged on a middle section of the door frame. Therefore, the at least one closing structure 14 includes two closing structures 14 that respectively close the two opposite ends of the handle buckle groove 131. In this case, the two ends of the handle lamp 2 are located between the two closing structures 14. Since the handle lamp 2 is long, it should not be located very tightly between the two closing structures 14 in the longitudinal direction to accommodate the length change of the handle lamp 2 due to temperature.

[0159] Fig. 9 A three-dimensional view of the door body viewed in the direction of the handle light 2 and a partial enlarged view of the corresponding area are shown. Fig.10 The three-dimensional view of the door body viewed in the direction of the handle light 2 and the partial enlarged view of the corresponding area are shown at different viewing angles.

[0160] from Fig. 9 The installation state of the handle light 2 in the handle buckle groove 131 can be clearly seen in the figure, and a closed structure 14 (upper closed structure) can also be seen.

[0161] Similarly, from Fig.10 The installation state of the handle light 2 in the handle buckle groove 131 can be clearly seen in the figure, and another closed structure 14 (lower closed structure) can also be seen.

[0162] Fig.11 An exploded view of a door handle 13 , a handle lamp 2 , a decorative panel 15 , and structures at both ends of the handle lamp according to an exemplary embodiment of the present invention is shown.

[0163] from Fig.11 As can be seen in the figure, the closed structures 14 at both ends are connected to the upper and lower non-handle sections of the door frame. The upper and lower non-handle sections of the door frame can also be seen from other figures. Preferably, the closed structure 14 is connected to the corresponding non-handle sections by locking.

[0164] According to an exemplary embodiment of the present invention, the lamp assembly can be electrically connected to the circuit system of the household appliance 1 at only one end. The circuit system of the household appliance 1, such as an electrical connector (not shown), can be arranged in the non-handle section. By making an electrical connection at only one end, the circuit arrangement can be simplified.

[0165] For example, a circuit system is provided in the upper non-handle section, and the upper closed structure 14 can be locked and connected to the upper non-handle section to cover the corresponding circuit system. The upper closed structure 14 can be provided with a structure for connecting wires to pass through.

[0166] To this end, according to an exemplary embodiment of the present invention, at the end of the lamp assembly electrically connected to the circuit system, the closing structure 14 is configured as an end cap to allow the circuit system to be detachably covered. The "detachable" connection facilitates the electrical connection operation.

[0167] To facilitate disassembly, according to an exemplary embodiment of the present invention, at least one enclosing structure 14 includes a detachable component to release the enclosure of the corresponding end of the lamp assembly. After the enclosure at the end of the lamp assembly is released, if there is no corresponding structure restricting the light outlet wall 221 side of the handle lamp 2, it is allowed to take out the lamp frame 22 from the receiving groove 11 in the direction opposite to the depth direction A.

[0168] According to an exemplary embodiment of the present invention, the length of the lamp assembly is less than the distance between the two enclosing structures 14, so that the lamp assembly is suitable for rotating around one end after the detachable component is removed. This means that the lamp assembly can be tilted and swung to remove the lamp frame 22 from the receiving groove 11. According to an exemplary embodiment of the present invention, the detachable component includes a cover for closing a cavity containing a connector for connecting the lamp assembly to the circuit system of the household appliance 1. In this case, the connector and the lamp frame are located on both sides of the cover, respectively.

[0169] If the lamp assembly does not need to be electrically connected at the lower enclosing structure 14, functionally it may not include detachable parts. To this end, a groove with a width of, for example, about 0.5 mm may be provided on the lower enclosing structure 14 to simulate a structure corresponding to the cover of the upper enclosing structure 14, thereby improving the quality of the household appliance 1.

[0170] In order to better demonstrate the present invention, Fig.12 Shows Figure 1 A cutaway top view of a side-by-side refrigerator is shown.

[0171] exist Fig.12In the figure, several observation directions are marked. The first observation direction V1 is the extreme observation position from the front of the refrigerator where the outermost position P1 of the handle buckle groove 131 where the handle lamp 2 is embedded can be observed. The second observation direction V2 is the observation direction from the front of the refrigerator to the innermost edge 152 of the decorative panel 15. The third observation direction V3 is the observation direction from the front of the refrigerator to the outermost edge P2 of the decorative panel 15.

[0172] In the first observation direction V1, the light emitting element 211 of the handle lamp 2 cannot be seen due to the tilted positioning relationship of the handle lamp 2 toward the decorative panel 15. In the process of moving from the first observation direction V1 to the second observation direction V2, although the light emitting wall 221 of the handle lamp 2 may be seen, the light emitting element 211 will never be seen directly through the light emitting wall 221, so that the user will not feel uncomfortable due to directly looking at the light emitting element 211 (although separated by the light emitting wall 221).

[0173] In the process of moving from the second observation direction V2 to the third observation direction V3, the user sees the area of ​​the decorative panel 15, and the angle α between the second observation direction V2 and the third observation direction V3 is relatively large, which is very advantageous.

[0174] To this end, according to an exemplary embodiment of the present invention, the handle light 2 is configured so that when both the double doors are closed, there is no sight line from outside the refrigerator door to the light emitting element 211. That is, the light assembly is configured so that when the user is located in front of the household appliance when both the double doors are closed, the light emitting element is out of the user's sight.

[0175] Next, we return to the description of the handlebar light 2 itself.

[0176] According to an exemplary embodiment of the present invention, in particular Figure 3-Figure 6 As shown, the light source assembly 21 further includes a printed circuit board 212 for carrying the light emitting element 211 on one side and a control chip 213 for controlling the light emitting element 211 on the other side of the printed circuit board 212 .

[0177] from Figure 3-Figure 6 It can also be seen that according to an exemplary embodiment of the present invention, the distance between the light emitting element 211 and the front surface of the door body is smaller than the distance between the central area of ​​the printed circuit board 212 and the front surface of the door body.

[0178] At this time, the first holding groove 2261 and the second holding groove 2262 hold the side edge of the printed circuit board 212 .

[0179] The control chip 213 can control the switch of the light emitting element 211, but more preferably, can also control the characteristics, such as the color, of the light emitted by the light emitting element 211. Since the arrangement of the control chip 213 on the printed circuit board 212 has no special influence, preferably, the control chip 213 is centrally located on the printed circuit board 212.

[0180] It is mentioned above that the width of the light source assembly 21 is preferably smaller than the width of the light exit wall 211 . When the light source assembly 21 includes a printed circuit board 212 , the size, especially the width, of the printed circuit board 212 is smaller than the corresponding size of the light exit wall 221 .

[0181] According to an exemplary embodiment of the present invention, in particular Figure 3-Figure 6 As shown, the printed circuit board 212 is arranged parallel to the light exit wall 221 .

[0182] In the case where the light source assembly 21 includes a printed circuit board 212 , the light emitting element 211 is offset on the printed circuit board 212 .

[0183] Especially if Figure 3-Figure 6 As shown, the light emitting element 211 is preferably arranged at a position corresponding to the edge 2131 of the control chip 213 .

[0184] According to an exemplary embodiment of the present invention, the light emitting element 211 is a light emitting diode.

[0185] In the present invention, from an optical point of view only, the light emitting wall 221 is only used to allow the light emitted by the light emitting element 211 to be emitted through the light emitting wall 221, without changing the propagation characteristics of the light emitted by the light emitting element 211. Therefore, the light emitting wall 221 can be configured as a flat plate.

[0186] In addition, the light emitting wall 221 is preferably translucent so that the light emitting element 211 cannot be seen through the light emitting wall 221 when the light emitting element 211 stops emitting light, which can improve the quality of the handle light 2.

[0187] Fig.13 An exploded view of a handle light 2 according to an exemplary embodiment of the present invention and a partial enlarged view of a corresponding area are shown.

[0188] like Fig.13 As shown, the size of the lamp frame 22 is consistent in the longitudinal direction and is in a strip shape. Preferably, the lamp frame 22 also has the same cross section in the longitudinal direction. In this case, the lamp frame 22 is preferably formed in one piece by an extrusion molding process. As mentioned above, since there is no need to mold claws or threaded holes, the extrusion molding process is particularly suitable for molding the lamp frame 22. Moreover, it is also convenient to cut the length of the lamp frame 22 as needed.

[0189] In addition, the light outlet wall 221 has a need for light transmission, while the rest of the light frame 22 does not have a need for light transmission. To this end, at least a portion of the light outlet wall 221 and the rest of the light frame 22 are made of the same material containing different coloring components. Made of the same material is convenient for one-piece molding using an extrusion molding process. For example, the light frame 22 can be made of acrylic material.

[0190] like Fig.13 As shown, the light source assembly 21 is configured in a strip shape. Preferably, a row of a plurality of light emitting elements 211 spaced apart from each other are arranged on the printed circuit board 212 so that the handle lamp 2 emits a light strip from the light emitting wall 221 to illuminate the decorative panel 15 obliquely.

[0191] like Fig.13 As shown, the lamp frame 22 is configured to be open at one end so as to allow the light source assembly 21 to be inserted from the end.

[0192] According to an exemplary embodiment of the present invention, the handle lamp 2 further includes corresponding end openings 229 ( Fig.13 Only one is shown in the figure, especially the elastic first cover 23 and the second cover 24. By closing the ends of the lamp frame 22 with the first cover 23 and the second cover 24, the light source assembly 21 in the lamp frame 22 can be protected.

[0193] The elastic end cap can be securely held in the end opening 229 and can compensate for changes in the length of the lamp frame 22 due to temperature changes.

[0194] As mentioned above, the handle lamp 2 can be electrically connected to the circuit system of the household appliance 1 at only one end thereof. Fig.13 As shown, only one of the first cover 23 and the second cover 24 ( Fig.13 A wire hole 241 is formed on the upper cover in the middle for the wire to pass through.

[0195] It should be pointed out here that although the concept of the present invention is described above using the handle lamp 2 as an example in conjunction with the accompanying drawings, it is obvious that this lamp assembly can also be used in other areas of household appliances, and is particularly suitable for being arranged in narrow and long areas, such as the edges of non-handles.

[0196] In addition, the present invention also relates to a household appliance, comprising: a door frame 17; and a lamp assembly installed on the door frame 17, especially a handle lamp 2. The lamp assembly comprises: a light source assembly 21, which comprises a light-emitting element 211; and a lamp frame 22 for accommodating the light source assembly 21, the lamp frame 22 comprises a light-emitting wall 221 towards which the light-emitting element 211 is directed, wherein the door frame 17 is provided with two mating structures 171 respectively mating with two opposite ends of the lamp assembly, the two mating structures 171 being configured to allow the lamp assembly to be longitudinally retained therebetween to limit the position of the lamp assembly, and both ends of the lamp assembly at least do not produce a structural bite action with the corresponding mating structure 171 in a direction opposite to the insertion direction of the ends of the lamp assembly toward the corresponding mating structure 171. The door frame 17 and the mating structure 171 can be referred to. Figure 2 The matching structure 171 may be a general concept of the above-mentioned closing structure 14 . For example, the matching structure 171 may be used only to hold the end of the handle light 2 .

[0197] According to an exemplary embodiment of the present invention, at least one of the two matching structures 171 overlaps with the corresponding end of the lamp assembly in the longitudinal direction to produce a limiting effect. "Vertical overlap" means that the end of the lamp assembly overlaps with the matching structure 171 in the longitudinal direction to produce a limiting effect in the direction perpendicular to the longitudinal direction, such as the depth direction A mentioned above. In principle, without considering the sealing performance, the matching structure 171 can also be a protruding structure that extends into the end opening 229 of the lamp frame 22, and the protruding structure can be directly constructed as the above-mentioned cover.
