DETAILED DESCRIPTION

[0026] A kitchen appliance generally includes a box body and a door, wherein a storage space is provided in the box body. A handle is provided on the outside of the door to facilitate opening and closing the door, and the handle is fixedly connected to the door through a connecting column. Existing handles are generally an integrated structure or a structure in which a front panel and a rear shell are attached, and their function is only for gripping, and their function is single, and it is inconvenient to expand their functions. Therefore, the present invention proposes a new handle and a kitchen appliance.

[0027] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. In this specification, the X direction refers to the front, that is, when the steamer is placed normally horizontally and the handle faces the user, the front of the steamer in the user's conventional cognition; the direction opposite to the X direction is the rear.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understood, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. For the convenience of description, when describing the handle of the present invention, the present description takes a steamer as an example.

[0029] like Figure 1-Figure 3 As shown, a handle according to an embodiment of the present invention comprises a handle body and two connecting columns 4 fixedly connected to the handle body. One end of the connecting column 4 is connected to the handle body, and the other end is fixedly connected to the door of the steamer. The two connecting columns 4 are evenly distributed.

[0030] The handle body includes a front panel 1, a rear shell 2 and an intermediate frame 3, and the intermediate frame 3 has sufficient supporting strength. The intermediate frame 3 is arranged between the front panel 1 and the rear shell 2, and the front panel 1 and the rear shell 2 are respectively fixedly connected to the intermediate frame 3. A clearance cavity 9 is arranged between the intermediate frame 3 and the front panel 1.

[0031] Due to the presence of the intermediate plate frame 3, the overall support strength of the handle is improved. At the same time, the clearance cavity 9 between the front panel 1 and / or the rear shell 2 and the support plate frame 3 is convenient for installing circuit boards, light-emitting components and other components that can be used to expand the function of the handle. The intermediate plate frame 3 can be made of materials with higher support strength, such as high-strength aluminum alloy and stainless steel. Since the intermediate plate frame 3 can be used to assume the main support function, the support function of the front panel 1 and the rear shell 2 is liberated to a certain extent. For example, when a circuit board and a light-emitting component are arranged in the clearance cavity 9, a light-transmitting area can be arranged on the front panel 1 or the rear shell 2 to achieve light transmission of the handle, and the circuit board and the light-emitting component can be fixedly mounted on the intermediate plate frame 3.

[0032] Optionally, the middle plate frame 3 includes a support plate 31 and a pressure strip 32. The support plate 31 is located between the front panel 1 and the rear shell 2. Pressure strips 32 are provided at the top and bottom of the support plate 31 (the top and bottom here and later refer to the top and the bottom of the component when the steamer is placed normally). The pressure strip 32 is integrally formed with the support plate 31. The front end of the pressure strip 32 is connected to the front panel 1, and the rear end of the pressure strip 32 is connected to the rear shell 2.

[0033] The front and rear sides of the pressure strip 32 are both provided with a support 35. The support 35 protrudes forward or backward relative to the support plate 31. The front panel 1 is in contact with the front surface of the support 35 on the front side of the pressure strip 32, and the rear shell 2 is in contact with the rear surface of the support 35 on the rear side of the pressure strip 32. The provision of the support 35 ensures that a clearance cavity 9 is formed between the support plate 31 and the front panel 1 and the rear shell 2. Of course, the clearance cavity 9 can also be provided on one side of the support plate 31. For example, the support 35 is provided on the front side of the pressure strip 32, and the support 35 is not provided on the rear side of the pressure strip 32, then the support plate 31 is directly in contact with the rear shell 2, and at this time, only the clearance cavity 9 is formed between the support plate 31 and the front panel 1.

[0034] The connection method of the front panel 1 and the rear shell 2 with the pressure strip 32 can be welding, screw connection or strong glue bonding. For example, screw holes can be set on the front panel 1, the rear shell 2 and the support 35 of the pressure strip 32, and the front panel 1, the rear shell 2 and the middle frame 3 are fixedly connected by screws, or strong glue can be set on the support 35 of the pressure strip 32 to press the front panel 1 and the rear shell 2 with the support 35.

[0035] A first protrusion 321 protruding forward is provided at the front end of the pressure strip 32, and a second protrusion 322 protruding backward is provided at the rear end of the pressure strip 32. The first protrusion 321 is used to limit the front panel 1, and the second protrusion 322 is used to limit the rear shell 2. The first protrusion 321 and the second protrusion 322 are respectively higher in the front and rear directions relative to the support platform 35 of the pressure strip 32. In addition, the inner wall of the first protrusion 321 is in contact with the top surface or bottom surface of the front panel 1, and the inner wall of the second protrusion 322 is in contact with the top surface or bottom surface of the rear shell 2. The inner wall here refers to the side walls opposite to the two first protrusions 321 and the side walls opposite to the two second protrusions 322.

[0036] When the front panel 1 and the middle frame 3 are assembled, the front panel 1 is located between the first protrusions 321 of the two pressure strips 32, which acts as a limit for the upper and lower positions of the front panel 1; the rear shell 2 is located between the second protrusions 322 of the two pressure strips 32, which acts as a limit for the upper and lower positions of the rear shell 2. Furthermore, the two first protrusions 321 are interference-fitted with the front panel 1, and the front panel 1 is inserted into the space between the two first protrusions 321, thereby achieving the fixing of the pressure strip 32 to the front panel 1; similarly, the two second protrusions 322 are interference-fitted with the rear shell 2, and the rear shell 2 is inserted into the space between the two second protrusions 322, thereby achieving the fixing of the pressure strip 32 to the rear shell 2.

[0037] It can be seen that the first protrusion 321 and the second protrusion 322 respectively limit and press the front panel 1 and the rear cover 2, further ensuring the assembly reliability of the front panel 1 and the rear cover 2.

[0038] At the same time, the first protrusion 321 covers the upper and lower edges of the front panel 1, and the second protrusion 322 covers the upper and lower edges of the rear shell 2, making the handle more beautiful.

[0039] like Figure 4 and Figure 5 As shown, a light source assembly is provided on the support plate 31 of the middle plate frame 3. The light source assembly includes at least a light emitting component 5, and a light-transmitting portion is provided on the side wall of the handle, where the handle side wall refers to the wall portion of the handle from the clearance cavity 9 to the outer surface of the handle. Specifically, a light-transmitting portion is provided on the side wall of at least one of the pressure strip 32, the front panel 1 and the rear shell 2, and the light emitting component 5 corresponds to the light-transmitting portion.

[0040] The handle is provided with a light source assembly and a light-transmitting portion, which can achieve a light-transmitting effect, making the handle more beautiful and easy to identify in a darker environment.

[0041] Optionally, the light source assembly includes a circuit board 6 and a light emitting component 5 , and the light emitting component may be an LED chip or an incandescent lamp, etc. The circuit board 6 is disposed in the clearance cavity 9 between the support plate 31 and the front panel 1 and in the clearance cavity 9 between the support plate 31 and the rear shell 2 .

[0042] The circuit board 6 is arranged in parallel with the support board 31 , and the circuit board 6 is fixedly connected with the support board 31 by screws. The light emitting component 5 is arranged on the top and bottom of the circuit board 6 .

[0043] Optionally, the light-transmitting portion includes a first light-transmitting portion 33 and a second light-transmitting portion.

[0044] A first light-transmitting portion 33 is provided at the top and / or bottom of the middle plate frame 3. Specifically, the first light-transmitting portion 33 is provided on the bead 32. The first light-transmitting portion 33 extends from the side wall of the clearance cavity 9 to the outer wall of the bead 32, and the outer wall of the bead 32 is the top surface or bottom surface of the handle. When the light-emitting component 5 emits light, the light can be irradiated from the clearance cavity 9 through the first light-transmitting portion 33 to the outside of the handle, forming a light-transmitting effect of the handle.

[0045] A light-transmitting portion is arranged on the top and / or bottom of the middle plate frame 3, so as to form a light-transmitting effect of the upper and lower contours of the handle.

[0046] The first light-transmitting portion 33 can be made by opening a light-transmitting hole on the pressure strip 32, and then placing a light-transmitting material in the light-transmitting hole, so as to block the light-transmitting hole and ensure the light-transmitting effect. Furthermore, the pressure strip 32 can directly use a light-transmitting material, and the pressure strip 32 is fixedly connected to the support plate 31. The light-transmitting material can be plastic, organic glass, etc. with a light transmittance of 40%-80%.

[0047] Preferably, the first light-transmitting portions 33 are in the shape of a strip, a grid or a dot, and are arranged in a straight line along the upper and lower contours of the handle.

[0048] Providing the first light-transmitting portion 33 in the shape of a strip, a grid or a dot can, on the one hand, reduce the difficulty of manufacturing to a certain extent, and on the other hand, is more suitable for being arranged along the edge of the handle, which is conducive to highlighting the outline of the handle.

[0049] Optionally, the grid-shaped and dot-shaped first light-transmitting portions 33 may also be arranged in sections or at intervals. For example, five grid-shaped first light-transmitting portions 33 are arranged between every five adjacent dot-shaped first light-transmitting portions 33 .

[0050] The first light-transmitting portion 33 can be arranged in different shapes to achieve different visual effects and meet the diverse needs of customers.

[0051] The front panel 1 is provided with a second light-transmitting portion. At this time, in order to achieve a better light-transmitting effect, a light-emitting component 5 is provided in front of the circuit board in the clearance cavity 9 between the support plate 31 and the front panel 1, and the position of the light-emitting component 5 corresponds to the position of the second light-transmitting portion. Of course, the second light-transmitting portion can also be provided on the rear shell 2, and a light-emitting component 5 corresponding to the second light-transmitting portion on the rear shell 2 can be additionally provided.

[0052] Preferably, a preset pattern is provided on the second light-transmitting portion. The preset pattern may be a company logo, company promotion text, or a cartoon image or animal or plant pattern. On the one hand, the handle becomes a relatively novel corporate advertising carrier, and on the other hand, the handle is more interesting and beautiful.

[0053] Furthermore, the front panel 1 and / or the rear shell 2 are made of a light-transmitting material with a light transmittance of less than 70%, thereby creating a crystal-clear light-transmitting effect for the entire handle.

[0054] In the above embodiments, a frosted layer may be provided on the surface of the light-transmitting portion. For example, the surface of the light-transmitting portion may be frosted to make the transmitted light softer. For example, in combination with the above embodiments, the front panel 1 or the rear shell 2 may be made of colorless transparent glass or colored glass. The colorless transparent glass will appear hazy milky white after frosting, and the colored glass will have a better decorative effect after frosting, which can better meet the personalized needs of users. Obviously, after the light-transmitting portion is frosted, the light transmission effect is softer and hazier, and the electrical components and circuits in the cavity 9 cannot be seen from the outside of the handle.

[0055] Preferably, the inner wall of the light-transmitting portion is provided with a colored coating, so that the handle can transmit light of different colors, further increasing the aesthetics.

[0056] like Figure 6 and Figure 7 As shown, for example, the middle plate 3 includes a support plate 31, which is a rectangular plate. A pressure strip 32 is provided on the top and bottom of the support plate 31, and the pressure strip 32 is perpendicular to the support plate 31. Side panels 36 are provided on the left and right sides of the support plate 31, and the side panels 36 are perpendicular to the support plate 31. The side panels 36 are connected to the pressure strip 32, so that the side panels 36 and the pressure strip 32 surround a mounting groove 34 on the surface of the support plate 31. In addition, one mounting groove 34 is formed on the front and rear sides of the support plate 31. Screw holes or positioning column structures can be provided on the mounting groove 34 for installing components such as circuit boards, light-emitting components and cables.

[0057] The first light-transmitting portion 33 is arranged on the pressure strip 32, which is equivalent to the groove wall of the mounting groove 34. In this embodiment, two parallel rows of first light-transmitting portions 33 are arranged on the pressure strip 32, one row of which is arranged on the groove wall of the mounting groove 34 located in front of the support plate 31, and the other row is arranged on the groove wall of the mounting groove 34 located behind the support plate 31. If the left and right light transmission of the handle is to be achieved, the first light-transmitting portion 33 can also be arranged on the side panel 36.

[0058] In the above embodiment, the structure of the middle plate frame 3 is merely exemplified. In fact, the structure of the middle plate frame 3 can be changed and improved. For example, a wire hole can be provided on the support plate 31 to facilitate the communication between the front side components and the rear side components of the support plate 31. However, these changes and improvements all belong to the scope of the present invention.

[0059] Another embodiment of the present invention provides a kitchen appliance, the kitchen appliance comprising the handle of the above embodiment. The kitchen appliance may be a steamer, an oven, a steam oven, a dishwasher, a disinfection cabinet, a microwave oven, etc.

[0060] Taking a steamer as an example, the steamer includes a box body and a door, the door is hinged to the door frame of the box body, and the door is provided with the handle described in the above embodiment. The handle is fixedly connected to the door through a connecting column 4. The light source assembly in the handle is electrically connected to the door through the connecting column 4, and then electrically connected to the electric control box of the steamer. Specifically, a wiring channel can be provided in the connecting column 4, and the cable connecting the light source assembly is connected to the circuit on the door through the wiring channel, and the circuit on the door is connected to the electric control box of the steamer through the cable between the door and the box body. In another embodiment, a battery accommodating cavity can be provided in the yield cavity 9 in the handle, and the battery accommodating cavity is used to install a battery for powering the light source assembly, and the battery can be a dry cell, a lithium battery, etc.

[0061] Although the present invention is disclosed as above, the present invention is not limited thereto.
