Description

Technical Field

[0001] The present disclosure relates to the field of household appliances, and in particular to a refrigerator. Background Art

[0002] As people's living standards continue to improve, refrigerators have become a necessity in people's lives. Refrigerators use refrigeration to keep their interior at a low temperature, which can not only preserve food, but also make ice by setting up ice-making components, greatly facilitating users' demand for ice cubes.

[0003] In the related art, a water injection device is usually provided inside the refrigerator, and water is injected into the ice-making component through the water injection device to make ice cubes in the ice-making component. However, when the water injection device injects water into the ice-making component, the injected water flow rate is too fast, which will cause water droplets to splash outside the ice-making component and other components. Long-term accumulation will cause problems such as water droplets freezing and circuit short circuit. Utility Model Content

[0004] In view of this, the present disclosure provides a refrigerator, which can reduce the water flow rate when injecting water into an ice-making component of the refrigerator, thereby avoiding problems such as water droplets freezing and circuit short circuit caused by splashing water.

[0005] Specifically, the present disclosure is implemented through the following technical solutions.

[0006] According to a first aspect of an embodiment of the present disclosure, a refrigerator is provided, comprising a liquid injection pipe, an ice-making component and a flow guide assembly. The ice-making component is provided with a water inlet. The flow guide assembly comprises a first connecting member and a second connecting member connected to the first connecting member. The first connecting member is provided with a first flow channel, and the second connecting member is provided with a second flow channel connected to the first flow channel. The length direction of the first flow channel is different from the length direction of the second flow channel. The first connecting member is connected to the liquid injection pipe, and the first flow channel is connected to the liquid injection pipe. The second connecting member is connected to the ice-making component through the water inlet. The inner side wall of the second flow channel is provided with at least one buffer groove, and at least part of the opening of the buffer groove faces the first flow channel.

[0007] The technical solution provided by the embodiments of the present disclosure may include the following beneficial effects.

[0008] When water is injected into the ice-making component, the injection pipe can provide water. The injection pipe is connected to the ice-making component through a guide assembly to inject water into the ice-making component for ice-making. The guide assembly includes a first connector and a second connector, and a first flow channel and a second flow channel that are interconnected are respectively provided on the first connector and the second connector. The injection pipe is connected to the first connector, and the injection pipe is connected to the first flow channel, and the second connector is connected to the ice-making component through a water inlet. The water in the injection pipe enters the ice-making component through the first flow channel and the second flow channel to make ice. When water flows from the first flow channel to the second flow channel, because the length directions of the first flow channel and the second flow channel are different, the water will turn to facilitate the injection of water into the ice-making component, and when the water flows from the first flow channel to the second flow channel, the water will collide with the inner side wall of the second flow channel, thereby reducing the water flow speed. In addition, at least one buffer groove is provided on the inner side wall of the second flow channel, and at least part of the opening of the buffer groove faces the first flow channel. The water will flow to the buffer tank, where the water flow rate is further reduced, and then flow to the second flow channel, thereby reducing the flow rate of water injected into the ice-making component, avoiding problems such as ice formation in the refrigerator and circuit short circuit caused by splashing water.

[0010] In one embodiment, the depth of the buffer groove is greater than or equal to 0.1 mm.

[0011] In one of the embodiments, the outer wall of the flow guide component is provided with a protrusion at the junction of the buffer groove and the flow guide component.

[0013] In one embodiment, the inner diameter of the injection tube is smaller than or equal to the inner diameter of the first flow channel.

[0014] In one embodiment, the first flow channel and / or the second flow channel is a blind hole.

[0015] In one embodiment, a plurality of flow guide members are protruded and spaced apart from each other in the circumferential direction of the inner side wall of the second flow channel, and the length direction of the flow guide members is the same as the length direction of the second flow channel.

[0018] In one embodiment, an inner side wall of the installation groove is provided with an introduction groove, and the injection tube passes through the introduction groove and is installed in the installation groove.

[0019] In one embodiment, the ice-making component further includes an ice tray, and the water inlet is located above the ice tray.

[0039] As people's living standards continue to improve, refrigerators have become a necessity in people's lives. Refrigerators use refrigeration to keep their interior at a low temperature, which can not only preserve food, but also make ice by setting up an ice-making device, greatly facilitating users' demand for ice cubes. At present, there are many types and brands of refrigerators, which makes consumers have many choices. How to win the favor of consumers and improve product competitiveness has become an issue that refrigerator manufacturers pay more and more attention to.

[0040] In the related art, a water injection device is usually provided inside the refrigerator, and water is injected into the ice-making device through the water injection device to make ice cubes in the ice-making device. However, when the water injection device injects water into the ice-making device, the injected water flow rate is too fast, which will cause water droplets to splash outside the ice-making device and other components. Long-term accumulation will cause problems such as water droplets freezing and circuit short circuit.

[0041] Based on this, the present disclosure provides a refrigerator 1, which can reduce the water flow rate when injecting water into the ice-making component 100 of the refrigerator 1, so as to prevent water droplets from splashing outside the ice-making component 100 and other components, causing problems such as water droplets freezing and circuit short circuit.

[0042] like Figure 1 as well as Figure 2 As shown, the present application provides a refrigerator 1, including a cabinet device 10, a compressor 20, a condenser 30, an evaporator 40 and an expansion valve 50. The cabinet device 10 includes a cabinet assembly 11, a freezing chamber 13, a refrigerating chamber 14 and a cabinet door assembly 12. The freezing chamber 13 and the refrigerating chamber 14 are respectively arranged in the cabinet assembly 11. The cabinet door assembly 12 includes a first cabinet door 12a and a second cabinet door 12b. The first cabinet door 12a is rotatably connected to the cabinet assembly 11 to open or close the freezing chamber 13. The second cabinet door 12b is rotatably connected to the cabinet assembly 11 to open or close the freezing chamber 13. The compressor 20, the condenser 30, the evaporator 40 and the expansion valve 50 are respectively arranged in the cabinet assembly 11, and at least part of the evaporator 40 is arranged in the freezing chamber 13.

[0043] Combination Figure 3As shown, when the refrigerator 1 is in operation, the compressor 20 outputs a high-temperature and high-pressure gaseous refrigerant to the condenser 30, and the high-temperature and high-pressure gaseous refrigerant is condensed into a medium-temperature and high-pressure refrigerant through the condenser 30. The medium-temperature and high-pressure refrigerant is further reduced in pressure and temperature by the expansion throttling effect of the expansion valve 50, and the low-temperature and low-pressure liquid refrigerant flows out of the expansion valve 50 to the evaporator 40. The low-temperature and low-pressure liquid refrigerant evaporates into a gaseous refrigerant in the evaporator 40. At least part of the evaporator 40 is arranged in the freezing chamber 13, so that the refrigerant absorbs a large amount of heat in the freezing chamber 13 during the evaporation process, thereby reducing the temperature in the freezing chamber 13, making it easier to use the freezing chamber 13 to freeze items and realize the refrigeration of the refrigerator 1. The refrigerant coming out of the evaporator 40 is replenished back to the compressor 20 to form a refrigerant circuit. In this way, the refrigerant circulates continuously in the refrigerant circuit to maintain the freezing environment of the freezing chamber 13 (for example, less than -1°C).

[0044] See you later Figure 2 As shown, an air duct 15 is provided between the refrigerating compartment 14 and the freezing compartment 13, so as to transport part of the cold air from the freezing compartment 13 to the refrigerating compartment 14 through the air duct 15, so as to reduce or maintain the low temperature environment of the refrigerating compartment 14 (for example, 2°C to 8°C).

[0045] like Figure 2 As shown, in some embodiments, along the height direction of the refrigerator 1, the freezing chamber 13 is arranged below the refrigerating chamber 14. The refrigerator 1 also includes a first fan (not marked) arranged in the box assembly 11. The air inlet end or the air outlet end of the first fan is connected to the air duct 15, which is used to transport part of the cold air from the freezing chamber 13 to the refrigerating chamber 14.

[0046] like Figure 2 As shown, the height direction of the refrigerator 1 is the Z-axis direction.

[0047] In some embodiments, the outer wall of the freezing chamber 13 is covered with an insulation layer (not shown) to separate the evaporator 40 from the compressor 20 and the condenser 30 .

[0048] In some embodiments, the outer wall of the freezing chamber 13 is covered with an insulation layer (not shown).

[0049] In some embodiments, the refrigerator 1 further includes an air-cooling heat dissipation assembly (not shown) disposed on the cabinet assembly 11 , and the air-cooling heat dissipation assembly can at least dissipate heat for the condenser 30 .

[0050] In some embodiments, the box assembly 11 further includes a fresh-keeping bin disposed in the box assembly 11 , and the fresh-keeping bin is disposed between the refrigerating bin 14 and the freezing bin 13 along the height direction of the refrigerator 1 .

[0051] In order to meet the needs of users for using ice cubes, such as Figure 4As shown, in some embodiments, the refrigerator 1 further includes an ice-making device 60 for making ice cubes. The ice-making device 60 includes an ice-making component 100 and a liquid injection component 200. The ice-making component 100 includes an ice tray 110 disposed in the freezing chamber 13. The liquid injection component 200 is used to inject liquid required for making ice cubes into the ice tray 110.

[0052] It should be noted that Figure 4 The first door 12a of the refrigerator 1 is shown to be open and not illustrated, and the second door 12b is in a closed state.

[0053] Optionally, in some embodiments, the liquid injection component 200 includes a water receiving assembly for communicating with an external liquid injection tube 220 .

[0054] like Figure 4 As shown, in one example, the liquid injection component 200 includes a liquid storage container 210 and a liquid injection pipe 220. The liquid storage container 210 is disposed in the refrigerating compartment 14, one end of the liquid injection pipe 220 is connected to the liquid storage container 210, and the other end of the liquid injection pipe 220 is disposed above the ice tray 110 along the height direction of the refrigerator 1.

[0055] Optionally, the liquid injection component 200 further includes a switch valve (not shown) disposed in at least one of the liquid storage container 210 and the liquid injection pipe 220 for opening the liquid injection component 200 to inject liquid into the ice tray 110 , or closing the liquid injection component 200 .

[0056] like Figure 4 As shown, in some embodiments, the ice tray 110 can be rotatably arranged in the freezing chamber 13, and has a liquid receiving state and an ice pouring state. The ice making component 100 also includes a driving assembly 120 and an ice storage container 130. The driving assembly 120 is arranged in the freezing chamber 13, and is used to drive the ice tray 110 to switch between the liquid receiving state and the ice pouring state. Along the height direction of the refrigerator 1, the ice storage container 130 is arranged below the ice tray 110. In this way, the ice storage container 130 can receive the ice cubes poured from the ice tray 110.

[0057] It should be noted that the ice tray 110 and the driving assembly 120 can be directly or indirectly disposed in the freezing chamber 13 .

[0058] like Figure 4 As shown, in some embodiments, the ice-making component 100 further includes a bearing assembly 140, and the bearing assembly 140 is fixed to the freezing chamber 13. The ice tray 110 is rotatably disposed on the bearing assembly 140. The driving assembly 120 is disposed on the bearing assembly 140. In this way, the ice tray 110 and the driving assembly 120 are integrated by the bearing assembly 140, so that the ice-making component 100 can be modularly assembled in the freezing chamber 13, which is conducive to improving the assembly efficiency of the refrigerator 1.

[0059] In some embodiments, the liquid storage container 210 is disposed on the second door 12b. Thus, the liquid storage container 210 is stored in the cold storage room through the second door 12b, so that the user can easily take and place the liquid storage container 210. In some embodiments, ice water can also be provided to the user.

[0060] like Figures 5 to 8 As shown, in some embodiments, the ice-making component 100 is provided with a water inlet 150. The flow guide assembly 300 includes a first connector 310 and a second connector 320 connected to the first connector 310. The first connector 310 is provided with a first flow channel 311, and the second connector 320 is provided with a second flow channel 321 connected to the first flow channel 311. The length direction of the first flow channel 311 is different from the length direction of the second flow channel 321. The first connector 310 is connected to the injection pipe 220, and the first flow channel 311 is connected to the injection pipe 220. The second connector 320 is connected to the ice-making component 100 through the water inlet 150. The inner side wall of the second flow channel 321 is provided with at least one buffer groove 301, and at least part of the opening of the buffer groove 301 faces the first flow channel 311.

[0061] In this way, when water is injected into the ice-making part 100, the injection pipe 220 can provide water. The injection pipe 220 is connected to the ice-making part 100 through the guide assembly 300 to inject water into the ice-making part 100 to make ice. The guide assembly 300 includes a first connector 310 and a second connector 320, and the first connector 310 and the second connector 320 are respectively provided with a first flow channel 311 and a second flow channel 321 that are connected to each other. The injection pipe 220 is connected to the first connector 310, and the injection pipe 220 is connected to the first flow channel 311, and the second connector 320 is connected to the ice-making part 100 through the water inlet 150. The water in the injection pipe 220 enters the ice-making part 100 through the first flow channel 311 and the second flow channel 321 to make ice. When water flows from the first flow channel 311 to the second flow channel 321, because the length directions of the first flow channel 311 and the second flow channel 321 are different, the water will make a turn, which is convenient for injecting water into the ice-making component 100, and when the water flows from the first flow channel 311 to the second flow channel 321, the water will collide with the inner wall of the second flow channel 321, thereby reducing the water flow rate. In addition, at least one buffer groove 301 is provided on the inner wall of the second flow channel 321, and at least part of the opening of the buffer groove 301 faces the first flow channel 311. So that the water will also flow to the buffer groove 301, and the flow rate of the water is further reduced in the buffer groove 301, and then flow to the second flow channel 321. Thereby reducing the flow rate of the water injected into the ice-making component 100, avoiding splashing water and causing ice formation in the refrigerator 1, circuit short circuit and other problems. Improve the user experience.

[0062] It should be noted that the number of the buffer tanks 301 can be one, two, or three, etc., as long as the water flow can be buffered, and no specific limitation is made here.

[0063] It should be noted that there are many specific implementations of the first connector 310 and the second connector 320, including integrally forming the first connector 310 and the second connector 320, separately manufacturing the first connector 310 and the second connector 320 and then assembling them, and so on.

[0064] In an example, Figure 5 As shown, the first connecting member 310 and the second connecting member 320 are integrally formed and manufactured, thereby reducing the number of assembly steps and improving the overall assembly efficiency.

[0065] It should be noted that there are many specific implementation methods for the injection tube 220 and the guide assembly 300, including integrally forming the injection tube 220 and the guide assembly 300, separately manufacturing the injection tube 220 and the guide assembly 300 and then assembling them, etc.

[0066] In an example, Figure 6 as well as Figure 7 As shown, the liquid injection pipe 220 and the flow guide assembly 300 are manufactured separately and then assembled. In this way, maintenance can be facilitated and maintenance costs can be reduced.

[0067] It should be noted that there are many ways to connect the injection tube 220 and the guide assembly 300, including but not limited to threaded connection, clamping connection, hot melt adhesive connection, etc.

[0068] In one example, the liquid injection tube 220 and the flow guide assembly 300 are bonded by hot melt adhesive. This connection method is simple, easy to implement, and convenient for the production of the liquid injection tube 220 and the flow guide assembly 300.

[0069] like Figure 7 As shown, in some embodiments, the ice making component 100 further includes an ice tray 110, and the water inlet 150 is located above the ice tray 110. In this way, the water in the injection pipe 220 flows into the ice tray 110 in the ice making component 100 through the guide assembly 300 to make ice cubes in the ice tray 110. The flow rate of the water passing through the guide assembly 300 is reduced, which prevents water from splashing to the outside of the ice tray 110 and causing water droplets to freeze, circuit short circuit and other problems. By setting the water inlet 150 above the ice tray 110, water can flow to the ice tray 110 by gravity.

[0070] It should be noted that the water inlet 150 is located above the ice tray 110. Figure 7 The positional relationship between the water inlet 150 and the ice tray 110 is shown. When the placement position of the ice-making component 100 is changed, the positional relationship between the water inlet 150 and the ice tray 110 will also change accordingly, and no more examples will be given here.

[0071] like Figure 7 As shown, in some implementation methods, the ice making component 100 further includes a housing assembly 160, and the water inlet 150 is disposed in the housing assembly 160. The housing assembly 160 is provided with a receiving cavity 161, and the ice tray 110 is disposed in the receiving cavity 161. In this way, the ice tray 110 is disposed in the receiving cavity 161 of the housing assembly 160, and the housing assembly 160 can protect the ice tray 110 and prevent dust.

[0072] like Figure 8 As shown, in some embodiments, the depth of the buffer groove 301 is greater than or equal to 0.1 mm. In this way, the depth of the buffer groove 301 is designed to be greater than or equal to 0.1 mm. When water flows from the first flow channel 311 to the buffer groove 301, the time of water in the buffer groove 301 becomes longer, and the flow rate of water can be further reduced, and then it flows to the second flow channel 321. Thereby, the flow rate of water injected into the ice-making component 100 is reduced, and problems such as ice formation in the refrigerator 1 and circuit short circuit caused by splashing water are avoided.

[0073] It can be understood that the depth of the buffer groove 301 can be 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 1 mm, 1.5 mm, etc.

[0074] like Figure 8 As shown, in some embodiments, the outer wall of the guide assembly 300 is provided with a protrusion 330 at the junction of the buffer groove 301 and the guide assembly 300. In this way, at the junction of the buffer groove 301 and the guide assembly 300, the outer wall of the guide assembly 300 is further provided with a protrusion 330, thereby increasing the wall thickness at the junction of the buffer groove 301 and the guide assembly 300, thereby improving the reliability of the guide assembly 300 and preventing the guide assembly 300 from being easily damaged at the buffer groove 301.

[0075] It can be understood that the connection between the buffer groove 301 and the guide component 300 is the position where the buffer groove 301 is opened on the inner wall of the guide component 300 .

[0076] like Figure 6 as well as Figure 8 As shown, in some embodiments, the first flow channel 311 and the second flow channel 321 are in the shape of holes, and the inner diameter of the second flow channel 321 is larger than the inner diameter of the first flow channel 311. In this way, when water flows from the first flow channel 311 to the second flow channel 321, the flow rate of water is constant during this process, and the inner diameter of the second flow channel 321 is designed to be larger than the inner diameter of the first flow channel 311, so that when water enters the second flow channel 321, the flow rate of water is reduced, thereby reducing the flow rate of water injected into the ice-making component 100, avoiding splashing water and causing ice formation in the refrigerator 1, circuit short circuit and other problems.

[0077] In some embodiments, a drilling machine is used to drill holes in the first connection member 310 and the second connection member 320 to form the first flow channel 311 and the second flow channel 321. In this way, the method of forming the first flow channel 311 and the second flow channel 321 is simple and easy to implement.

[0078] Furthermore, in some embodiments, the drilling depth of the first connecting member 310 can be deeper to form the first flow channel 311 and the buffer groove 301 on the inner wall of the flow guide component 300. In this way, the buffer groove 301 is formed in a simple manner and is easy to manufacture.

[0079] like Figure 5 As shown, in some embodiments, the first flow channel 311 is a blind hole, the second flow channel 321 is a blind hole, or both the first flow channel 311 and the second flow channel 321 are blind holes.

[0080] like Fig. 9 as well as Fig.10 As shown, in some embodiments, the inner diameter of the injection pipe 220 is smaller than or equal to the inner diameter of the first flow channel 311. In this way, when water flows from the injection pipe 220 to the first flow channel 311, the inner diameter of the injection pipe 220 is smaller than the inner diameter of the first flow channel 311, so that the water can flow more directly into the first flow channel 311, and the speed of water flowing from the injection pipe 220 to the first flow channel 311 is reduced, thereby reducing the flow rate of water injected into the ice-making component 100.

[0081] like Figure 8 As shown, a plurality of guide members 304 are protruded at intervals in the circumferential direction of the inner wall of the second flow channel 321, and the length direction of the guide members 304 is the same as the length direction of the second flow channel 321. In this way, when the water flows from the first flow channel 311 to the second flow channel 321, the plurality of guide members 304 protruded on the inner wall of the second flow channel 321 can play a role in beaming the water flow, preventing the water flow from rotating in the second flow channel 321, thereby preventing the water flow from splashing when it flows out.

[0082] It should be noted that the number of the flow guide members 304 can be two, three, or four, etc. It can be set according to actual needs and is not limited here.

[0083] It should be noted that the thickness of the guide member 304 is greater than or equal to 5 mm. Specifically, the thickness of the guide member 304 can be 5 mm, 6 mm, 8 mm, 10 mm, 12 mm, 15 mm, etc.

[0084] like Figure 8As shown, the second connecting member 320 includes a first end portion 322 located in the ice-making component 100, and the end surface 305 of the first end portion 322 is arranged in an inclined surface. Thus, when the water flows to the second flow channel 321, that is, the first end portion 322, the end surface 305 of the first end portion 322 is arranged in an inclined surface, so that the water flow is further prevented from rotating in the second flow channel 321, thereby preventing the water flow from splashing when it flows out.

[0085] like Fig. 9 As shown, in some embodiments, the first connecting member 310 includes a first connecting portion 312 and a second connecting portion 313 connected to the first connecting portion 312; the first connecting portion 312 is provided with a first flow channel 311; the second connecting portion 313 is provided with a mounting groove 302 communicating with the first flow channel 311; at least part of the injection tube 220 is installed in the mounting groove 302. In this way, by providing the mounting groove 302 in the second connecting portion 313 of the first connecting member 310, and the injection tube 220 is installed in the mounting groove 302, the connection between the flow guide assembly 300 and the injection tube 220 is realized. The mounting groove 302 is connected to the first flow channel 311 of the first connecting portion 312, so that the water in the injection tube 220 enters the second flow channel 321 through the first flow channel 311 and is finally injected into the ice-making component 100 to make ice.

[0086] It can be understood that the injection tube 220 is connected to the guide assembly 300 through the installation groove 302, and the hot melt adhesive is then bonded between the injection tube 220 and the inner wall of the installation groove 302 to achieve further bonding of the injection tube 220 and the guide assembly 300.

[0087] In order to facilitate the installation of the injection tube 220 into the installation groove 302, as shown in FIG. Figure 7 As shown, in some embodiments, the inner wall of the mounting groove 302 is provided with an introduction groove 303, and the injection tube 220 passes through the introduction groove 303 and is installed in the mounting groove 302. In this way, by providing the introduction groove 303 on the inner wall of the mounting groove 302, the injection tube 220 is easily installed in the mounting groove 302 through the introduction groove 303, thereby improving the assembly speed of the refrigerator 1.

[0088] It should be noted that there may be many specific implementations of the introduction groove 303 , including but not limited to chamfering or rounding the inner wall of the installation groove 302 .

[0089] like Fig.10 As shown, in one example, at the opening of the mounting groove 302 , the inner side wall of the mounting groove 302 is provided with a chamfer.

[0090] It should be noted that the above embodiments can complement each other if there is no conflict.

[0091] The components included in the "component", "device" and "equipment" disclosed in the present invention can also be flexibly combined, that is, modular production can be carried out according to actual conditions and modular assembly can be carried out as an independent module; or they can be assembled separately to form a module in the present device.

[0092] The division of the above components in the present disclosure is only one of the embodiments, for the convenience of reading, rather than limiting the scope of protection of the present disclosure. As long as the above components are included and have the same function, it should be understood that they are equivalent technical solutions of the present disclosure. In the description of the present disclosure, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, only for the convenience of describing the present disclosure and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present disclosure.

[0093] In addition, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first", "second", etc. may explicitly or implicitly include at least one of the features. In the description of the present disclosure, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0094] In the present disclosure, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the communication between the internal parts of two components or the interaction relationship between two components, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0095] In the present disclosure, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.
