DETAILED DESCRIPTION
[0030] In order to enable those skilled in the art to better understand the disclosed solution, the technical solution in the disclosed embodiment will be clearly and completely described below in conjunction with the drawings in the disclosed embodiment. Obviously, the described embodiment is only a part of the disclosed embodiment, not all of the embodiments. Based on the embodiments in the disclosed embodiment, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the disclosed embodiment.
[0031] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present disclosure described can be implemented in sequences other than those illustrated or described herein.
[0032] In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or modules is not necessarily limited to those steps or modules explicitly listed, but may include other steps or modules not explicitly listed or inherent to these processes, methods, products, or apparatuses.
[0033] For ease of understanding and explanation, the following Figures 1 to 4 The door assembly for kitchen appliances and the kitchen appliances having the door assembly provided by the embodiments of the present disclosure are described in detail.
[0034] Please refer to Figure 1 , which is a structural schematic diagram of a door assembly for kitchen appliances provided by an embodiment of the present disclosure. The door assembly 1 includes a housing 11, an air guide channel 12, and a heat sink 13, wherein the air guide channel 12 is arranged in the housing 11, and has an air inlet 121 for air flow to enter the air guide channel 12 and an air outlet 122 for air flow out of the air guide channel 12, and the heat sink 13 is arranged on the back of the key panel 2, and is located on the flow path of the air flow in the air guide channel 12. The advantage of such a setting is that the embodiment of the present disclosure can actively and efficiently conduct the heat of the key panel 2 to the air guide channel 12 through the heat sink 13, and then use the air inlet 121 and the air outlet 122 on the housing 11 to quickly blow the heat out of the air duct to avoid accumulation, and at the same time, the air guide channel 12 can also block the hot air in other positions in the door assembly 1 from blowing to the key panel 2, which greatly improves the heat dissipation efficiency and prolongs the service life, and the heat dissipation structure is simple, which effectively reduces the manufacturing cost.
[0035] The following is a detailed description of the air guide channel 12 and the heat sink 13 in the door assembly 1 of the embodiment of the present disclosure. ① In the embodiment of the present disclosure, the air guide channel 12 can be an independent component. For example, the air guide channel 12 is a rectangular parallelepiped with openings on both sides, and an outer surface of the rectangular parallelepiped is provided with an assembly port for placing the heat sink 13, wherein one end of the rectangular parallelepiped is opened to connect to the air inlet 121 of the outer shell 11, and the other end is opened to connect to the air outlet 122 of the outer shell 11. The advantage of such a setting is that it is tightly sealed, which greatly avoids the hot air in other positions of the door assembly 1 from blowing to the button panel 2. It can be understood that the air guide channel 12 can also have only three outer surfaces on the basis of the above-mentioned rectangular parallelepiped, that is, share the inner surface of the outer shell 11, and there is no need to set an assembly port in this case. The advantage of such a setting is that it can not only save raw materials and reduce manufacturing costs, but also facilitate installation and improve production efficiency.
[0036] Alternatively, in some embodiments of the present disclosure, the air guide channel 12 can also be formed by other components of the door assembly 1, thereby occupying less space and facilitating reducing the thickness of the door assembly 1. For example, the housing 11 has a first door body 111 and a second door body 112 arranged front and back, and the first door body 111 has an operation area for operating the key panel 2, and the key panel 2 is arranged in the operation area of the first door body 111. Among them, the key panel 2 can be pasted on the operation area, or it can also be arranged in a groove 1111 near the operation area, that is, the rear side of the operation area of the first door body 111 has the groove 1111 for the key panel 2 to be embedded. It can be understood that the operation area has a visual feature, so that it is easy to operate the key panel 2, which is more humane.
[0037] Furthermore, if Figure 2 As shown, there are two partitions 123 extending in the same direction between the first door body 111 and the second door body 112, and a gap is left between the two partitions 123, so that the air guide channel 12 is formed when the first door body 111 and the second door body 112 are in an assembled state. For example, the two partitions 123 are both extended backward from the rear wall plate of the first door body 111, and the two are arranged adjacent to the upper edge of the first door body 111, and the flow direction of the airflow in the air guide channel 12 is consistent with the length direction a of the first door body 111, and the air inlet 121 and the air outlet 122 are respectively opened on both sides of the first door body 111.
[0038] Optionally, the longitudinal cross-sectional area S1 of the air inlet flow section in the air guide channel 12 of the embodiment of the present disclosure gradually increases along the flow direction of the airflow, that is, the air inlet space becomes larger and larger; or, the longitudinal cross-sectional area S2 of the air outlet flow section in the air guide channel 12 of some embodiments of the present disclosure gradually decreases along the flow direction of the airflow, that is, the air outlet space becomes smaller and smaller; or, the longitudinal cross-sectional area S1 of the air inlet flow section in the air guide channel 12 of other embodiments of the present disclosure gradually increases along the flow direction of the airflow, while the longitudinal cross-sectional area S2 of the air outlet flow section gradually decreases along the flow direction of the airflow. The advantage of such a setting is that a pressure difference can be formed in the air guide channel 12, which is convenient for rapid heat exchange between cold and hot air.
[0039] Furthermore, in the embodiment of the present disclosure, a heat dissipation fan 124 is also provided in the air guide channel 12, and the heat dissipation fan 124 can be arranged at the air outlet 122, thereby increasing the wind force in the air guide channel 12 and further improving the heat dissipation effect.
[0040] ② In the embodiments of the present disclosure, the heat sink 13 may be a thermally conductive silicone sheet. The advantages of such a configuration are that it is heat-resistant, chemically resistant, and has good thermal conductivity. It is also convenient and quick to produce and install, and has low manufacturing costs. Alternatively, in some embodiments of the present disclosure, the heat sink 13 may also be thermally conductive silicone grease. The advantages of such a configuration are that it is high temperature resistant, anti-aging, and has excellent thermal conductivity and electrical insulation properties. It can protect the circuit while conducting heat and improve the stability of the circuit. Alternatively, in other embodiments of the present disclosure, the heat sink 13 may also be a combination of thermally conductive silicone grease and thermally conductive silicone sheet, thereby meeting diverse usage requirements and having a wide range of applications.
[0041] Further, taking the heat sink 13 as an example, the connection methods of the heat conductive silicone sheet and the key panel 2 in the disclosed embodiment include but are not limited to the following two methods: First, the heat conductive silicone sheet is directly attached to the back of the key panel 2. The advantages of this arrangement are simple structure, convenient installation, and convenient subsequent maintenance. Figure 3 As shown, the second door body 112 is also provided with an elastic structure, which has at least one elastic pressing sheet 1121, and the elastic pressing sheet 1121 can act on the thermally conductive silicone sheet (i.e., the heat sink 13) so that the heat sink 13 always has a tendency to move into the embedding groove 1111. For example, the elastic structure may include a first elastic pressing sheet and a second elastic pressing sheet symmetrically distributed on both sides of the middle of the thermally conductive silicone sheet. The advantage of such a setting is that the back of the thermally conductive silicone sheet can be evenly stressed, and the thermally conductive silicone sheet has a certain degree of softness, so that it can be firmly fixed.
[0042] Furthermore, in the embodiment of the present disclosure, a positioning structure is further provided on the second door body 112, and the positioning structure has at least one positioning pin 1122, thereby playing a role in rapid positioning during the installation process of the heat sink 13. For example, the positioning mechanism may include a first positioning pin located in the middle of the thermally conductive silicone sheet, and a second positioning pin and a third positioning pin located at both ends of the thermally conductive silicone sheet, wherein the height of the second positioning pin and the height of the third positioning pin are both greater than the height of the first positioning pin, thereby being able to assist in fixing the thermally conductive silicone sheet while installing and positioning the thermally conductive silicone sheet.
[0043] Optionally, in the embodiment of the present disclosure, the coverage area of the heat sink 13 is greater than or equal to the back area of the key panel 2 , thereby improving the thermal conductivity and achieving rapid heat dissipation of the key panel 2 .
[0044] Optionally, the heat sink 13 in the disclosed embodiment has a heat dissipation groove, and the extension direction of the heat dissipation groove is consistent with the flow direction of the airflow in the air guide channel 12. For example, along the length direction a of the first door body 111, at least two fins are provided on the rear side of the heat sink 13, and a heat dissipation groove is formed between adjacent fins. The advantage of such a setting is that the heat dissipation area can be increased, which is conducive to the heat dissipation to the air guide channel 12, and the heat conduction efficiency is further improved.
[0045] For example, the following is combined Figure 2 The door assembly 1 of the disclosed embodiment is described in detail as shown. For example, the heat sink 13 on the back of the button panel 2 in the disclosed embodiment is a thermally conductive silicone sheet, which can be installed and positioned by the positioning structure on the second door body 112, and is squeezed and fixed by the elastic structure. At the same time, the coverage area of the thermally conductive silicone sheet is larger than the back area of the button panel 2, and the thermally conductive silicone sheet has a heat dissipation groove, thereby greatly improving the thermal conductivity efficiency, which is convenient and fast. In addition, the button panel 2 can be fixed to the first door body 111 by screws 1112, and the four corners of the thermally conductive silicone sheet are chamfered, so that the thermally conductive silicone sheet can be accurately positioned by chamfering and screws 1112, which greatly improves production efficiency.
[0046] For another example, in the embodiment of the present disclosure, an outer glass 1113 is attached to the front of the first door body 111, and a handle 1114 is provided on the outer glass 1113 in a direction away from the front of the first door body 111. The advantage of such a configuration is that the baking state of the food in the kitchen appliance can be observed through the outer glass 1113, and the first door body 111 can be opened by the handle 1114 to avoid scalding and ensure safety in use.
[0047] For example, in the embodiment of the present disclosure, the second door body 112 is also provided with a middle glass 1123 and an inner glass 1124 in sequence in the direction away from the positioning structure and the elastic structure, so that the thermal conductive silicone sheet and the air guide channel 12 can be arranged between the first door body 111 and the second door body 112, and the hot air can be blocked from blowing to the back of the button panel, thereby effectively reducing the temperature of the button panel.
[0048] For example, in the embodiment of the present disclosure, the air guide channel 12 can be formed by the ribs, and the air channel formed by the ribs can also prevent the hot air from other positions in the door body from blowing toward the back of the key panel. In addition, the heat dissipation fan 124 located at the air outlet 122 can quickly inhale the cool air outside the door body from the air inlet 121, and efficiently discharge the heat conducted by the heat dissipation element 13 to the outside of the door body through the air outlet flow section, forming a cold and heat exchange cycle, and the heat dissipation effect is better.
[0049] The door assembly provided by the disclosed embodiment arranges a heat sink on the back of the key panel, and the heat sink is located on the flow path of the airflow in the air guide channel in the shell, thereby actively and efficiently transferring the heat of the key panel to the air guide channel, and then utilizing the air inlet provided on the shell for the air flow to enter the air guide channel and the air outlet provided on the shell for the air flow to flow out of the air guide channel to quickly blow out the heat from the air duct to avoid accumulation; at the same time, the air guide channel can also block the hot air from other positions in the door assembly from blowing toward the key panel, thereby greatly improving the heat dissipation efficiency and extending the service life; the heat dissipation structure is simple, and the manufacturing cost is effectively reduced.
[0050] As another aspect, the present disclosure provides a kitchen appliance. Figure 4 As shown, it is a structural block diagram of a kitchen appliance provided by an embodiment of the present disclosure. The kitchen appliance 3 may include Figure 1 to Figure 3 The door assembly 1 of the corresponding embodiment. In actual production, the door assembly 1 can be rotatably connected to the kitchen appliance 3. For example, the kitchen appliance 3 includes but is not limited to an oven, a steam-bake machine, and a steam-bake micro-in-one machine.
[0051] It should be noted that, for the description of the same contents in this embodiment as those in other embodiments, reference can be made to the description in other embodiments and will not be repeated here.
[0052] The door assembly of the kitchen appliance provided in the embodiment of the present disclosure is provided with a heat sink on the back of the key panel, and the heat sink is located on the flow path of the air flow in the air guide channel in the shell, thereby actively and efficiently transferring the heat of the key panel to the air guide channel, and then utilizing the air inlet provided on the shell for the air flow to enter the air guide channel and the air outlet provided on the shell for the air flow to flow out of the air guide channel to quickly blow the heat out of the air duct to avoid accumulation. At the same time, the air guide channel can also block the hot air from other positions in the door assembly from blowing toward the key panel, thereby greatly improving the heat dissipation efficiency and extending the service life. In addition, the heat dissipation structure is simple, which effectively reduces the manufacturing cost.
