Description

Technical Field

[0001] This utility model relates to the field of household appliance face mask design technology, specifically to a face mask device and a ceiling appliance having the same. Background Technology

[0002] Existing home appliances are trending towards intelligent development, with an increasing number of devices incorporating display components for human-computer interaction, information display, and lighting functions. For ceiling-mounted appliances (such as bathroom heaters, air conditioners, fresh air systems, and ventilation fans), the display components are typically installed inside the appliance before it leaves the factory, particularly on the appliance's housing. The installation method involves mounting the main body of the display component inside the housing, closest to the main body of the appliance, with only the display screen exposed on the housing. A fixed connection structure is used to connect the display component to the casing (or housing). This approach improves the integration and protection of the ceiling appliance, and by exposing only the display screen, it enhances the product's aesthetics.

[0003] However, the existing solutions have the following technical problems:

[0004] First, for some ceiling-mounted electrical appliances (such as linear bathroom heaters), their structure and size make it difficult, or even impossible, to install the display components inside the appliance casing (or cover) before leaving the factory.

[0005] Secondly, the existing ceiling electrical appliances and display components are connected by a fixed connection structure, which has the drawbacks of complicated installation procedures and low installation efficiency.

[0006] Third, existing technologies still present the problem of difficulty in disassembling display components by hand, causing great inconvenience for subsequent after-sales maintenance. When repairing display components, the housing (or cover) of the ceiling appliance must first be completely removed before tools can be used to inspect and repair the display components.

[0007] There is currently no effective solution to the aforementioned problems in the existing technology. Utility Model Content

[0008] The main objective of this invention is to provide a mask device and a ceiling appliance having the same, in order to solve the problem of inconvenient installation of display components in existing household appliances.

[0009] To achieve the above objectives, according to one aspect of the present invention, a face mask device is provided, comprising: a face mask assembly; a display assembly having a mounting member and a display, a first end of the mounting member being connected to the display, and a second end of the mounting member having a connecting end; the mounting member being detachably connected to the face mask assembly via the connecting end in a direction toward the face mask assembly from the outside of the face mask assembly.

[0010] Furthermore, the mounting component has a connection position that is at least partially inserted into the face mask assembly, and the mounting component has an assembly position that is detached from the face mask assembly.

[0011] Furthermore, the connecting end has an initial state and a deformed state. During the process of the mounting part moving from the assembly position to the connecting position, the connecting end switches from the initial state to the deformed state until it is inserted into the mask assembly.

[0012] Furthermore, the mounting component is threadedly connected to the mask assembly.

[0013] Furthermore, the second end of the mounting component is detachably inserted into the face mask assembly along the height direction of the face mask assembly. The mounting component is in an initial state before insertion, and after insertion begins, the mounting component deforms from the initial state along the side of the geometric center line of the face mask assembly along its length until it is inserted into the face mask assembly.

[0014] Furthermore, the connecting end has at least one first connecting portion, and the mask assembly has at least one second connecting portion, with the first connecting portion and the second connecting portion correspondingly disposed; wherein, when the connecting end is inserted into the mask assembly, the first connecting portion and the second connecting portion engage.

[0015] Furthermore, the connecting end includes two oppositely arranged connecting plates, with a gap space formed between the two oppositely arranged connecting plates, and at least one of the two connecting plates is provided with at least one first connecting part; wherein, when at least one connecting plate is pressed, the connecting end is in a deformed state, and the pressed connecting plate moves toward the other opposite connecting plate.

[0016] Furthermore, the connecting end is an annular thin-walled structure, and at least one first connecting part is provided on the outer wall of the thin-walled structure; wherein, when at least one part of the outer wall of the thin-walled structure is compressed, the connecting end is in a deformed state, and the compressed part of the outer wall is recessed toward the central axis of the thin-walled structure.

[0017] Furthermore, the mask assembly is provided with an installation space, and when the connecting end is connected to the mask assembly, at least one of the first connecting part and the second connecting part is located within the installation space.

[0018] Furthermore, the display includes: a display base connected to a first end of a mounting component, the display base having a receiving cavity; and a control circuit board located within the receiving cavity.

[0019] Furthermore, a wire-passing hole is provided near the connection end of the display base, and a wire-passing space is formed inside the connection end, with the wire-passing hole communicating with the wire-passing space.

[0020] Furthermore, the display includes: a display faceplate located within a receiving cavity, the display faceplate being located on the side of the control circuit board away from the connection end, and the display faceplate being electrically connected to the control circuit board.

[0021] Furthermore, the display includes: a mounting cover plate located on the side of the display surface away from the connection end, the mounting cover plate being connected to the display base to seal the receiving cavity; the mounting cover plate is provided with a first thread, and the display base is provided with a second thread, the first thread and the second thread being configured to engage.

[0022] According to another aspect of the present invention, a ceiling electrical appliance is provided, including a mask device, wherein the mask device is the aforementioned mask device.

[0023] By applying the technical solution of this utility model, the display component is detachably connected to the mask assembly via a connecting end. Compared with the existing fixed connection scheme, this simplifies the cumbersome installation process and improves installation efficiency. Furthermore, the mounting component connects to the mask assembly along its outer side, allowing for the installation of the display component from the outside of the mask assembly, even for ceiling appliances with limited size or special structures. This eliminates the need to install the display component inside the mask assembly; instead, it allows for connection from the outside after the mask assembly is installed. This removes the structural and dimensional limitations of the mask assembly on the installation of the display component, enabling more ceiling appliances to be equipped with display components and improving the user experience. The technical solution of this application effectively solves the problem of inconvenient installation of display components in household appliances in the prior art. Attached Figure Description

[0037] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0038] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0039] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0040] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of this application is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art. In the drawings, for clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to denote the same devices, and therefore their description will be omitted.

[0041] Home appliances are usually equipped with display components to display information. Some display components can interact with users through screen touch and other means. Whether home appliances are equipped with display components has become a key factor affecting the user experience.

[0042] Existing household appliances, especially ceiling-mounted appliances, typically have the display components installed from the inside of the casing or cover to the outside before the product leaves the factory, so that only the display screen is exposed on the cover. However, for some devices with special structures, the display components cannot be installed inside the cover at the factory. In such cases, the display components must be fixed after the ceiling appliance is installed, which may prevent the product from being installed and is very inconvenient.

[0043] For example, linear bathroom heaters feature a narrower mask assembly, which is popular with users due to its unique appearance and highly integrated structure. The width of the mask in a linear bathroom heater is typically smaller than the width of the display component. Therefore, the mask assembly cannot be integrated into the linear bathroom heater at the factory; the display component can only be considered after the housing and mask of the linear bathroom heater are installed.

[0044] During the installation of a linear bathroom heater, the faceplate and surrounding panels must be installed first before the display component can be installed. If the display component is installed on the faceplate first, interference and limitation will occur during the installation of the faceplate and panels. To ensure the display effect, the size of the display component cannot be designed to be smaller. Therefore, the installation of the display component and the faceplate can only rely on some fixed connection methods (such as adhesive bonding), which has the drawbacks of inconvenient installation and disassembly. Due to the special environment of ceiling-mounted electrical installation, installers need to position the components upwards and use tools to tighten them, which is extremely inconvenient and even poses safety risks. Furthermore, the faceplate is relatively narrow, and the connection strength between the two will be affected by the above-mentioned fixed connection methods.

[0045] Furthermore, the installation of the display component and the mask component relies on a fixed connection structure, which is complex and almost impossible to disassemble by hand during later use. If the display component has after-sales problems, the after-sales repair process requires the complete removal of the mask component before the display component can be removed, causing great inconvenience to later after-sales maintenance.

[0046] Solving the above problems and removing the installation restrictions caused by the unreasonable connection structure between the ceiling electrical appliances and the display components is of great importance for the further market promotion of the aforementioned ceiling electrical appliances. However, no effective solution has been proposed at present.

[0047] Combination Figures 1 to 9 As shown, according to a specific embodiment of this application, a face mask device is provided.

[0048] Combination Figure 1 , Figure 3 and Figure 9 As shown, the face mask device includes a face mask assembly 1 and a display assembly 2. The display assembly 2 has a mounting member 21 and a display 22. A first end of the mounting member 21 is connected to the display 22, and a second end of the mounting member 21 forms a connecting end 211. Along the outer side of the face mask assembly 1 toward the face mask assembly 1, the mounting member 21 is detachably connected to the face mask assembly 1 via the connecting end 211.

[0049] By applying the technical solution of this application, the display component 2 is detachably connected to the mask assembly 1 via the connecting end 211. Compared with the existing fixed connection scheme, this simplifies the complicated installation procedure and improves installation efficiency. Furthermore, the mounting part 21 is connected to the mask assembly along the outside of the mask assembly towards the mask assembly, allowing for the installation of the display component 2 from the outside of the mask assembly 1, eliminating the need to install it inside the mask assembly 1 for some ceiling appliances with limited size or special structure. This removes the structural and dimensional limitations of the mask assembly 1 on the installation of the display component 2, enabling more ceiling appliances to be equipped with display components and improving the user experience. The technical solution of this application effectively solves the problem of inconvenient installation of display components in household appliances in the prior art.

[0050] Specifically, faceplate assemblies are typically used to protect the internal components of electrical appliances, provide a user interface, and offer external aesthetics. The outer side of faceplate assembly 1 refers to the side of the faceplate assembly that faces away from the internal components of the ceiling-mounted electrical appliance. For example, when a linear bathroom heater is installed on a ceiling structure (a single large panel or integrated ceiling panel), the side furthest from the ceiling structure is the outer side of the faceplate assembly.

[0051] Optionally, during the connection process between the mounting component 21 and the mask assembly 1, at least a portion of the connection end 211 moves from the outside of the mask assembly 1 toward the mask assembly 1 until it is connected to the mask assembly 1.

[0052] Furthermore, the mounting component 21 has a connection position that is at least partially inserted into the face mask assembly 1, and a separation position from the face mask assembly 1 for assembly. That is to say, the mounting component 21 and the face mask assembly 1 adopt a plug-in connection, which has advantages such as quick connection and small space occupation of the connection structure.

[0053] Furthermore, the connecting end 211 has an initial state and a deformed state. During the process of the mounting component 21 moving from the assembly position to the connection position, the connecting end 211 switches from the initial state to the deformed state until it is inserted into the mask assembly 1. By forming a connecting end 211 with an initial state and a deformed state in the mounting component 21, the display component 2 can be detachably connected to the mask assembly 1 directly using the connecting end 211 only through the state transition of the connecting end 211, avoiding the installation difficulties that exist when using fixed connections (such as adhesive) between the mask assembly 1 and the display component 2.

[0054] Furthermore, the mounting component 21 is threadedly connected to the face mask assembly 1. The connecting end 211 has a threaded structure that mates with the mounting position on the face mask assembly. The connecting end 211 is threaded onto the face mask assembly by at least one of screws, bolts, or studs. Connecting the face mask assembly 1 and the display assembly 2 using screws, bolts, or studs offers advantages such as high connection stability, simple structure, and low cost.

[0055] Furthermore, the second end of the mounting member 21 is detachably inserted into the face mask assembly 1 along its height direction. The mounting member 21 is in its initial state before insertion. After insertion begins, the mounting member 21 deforms from its initial state along the geometric center line of the face mask assembly 1 along its length until it is fully inserted into the face mask assembly 1. Before insertion, the mounting member 21 is in its initial state; after insertion begins, it enters a deformation state and begins to deform in the direction of the geometric center line of the face mask assembly 1 along its length. This allows the connecting end 211 to reduce its volume through deformation to avoid structural interference into the face mask assembly 1, until it is fully inserted into the face mask assembly 1. At this point, the mounting member 21 tends to return from its deformed state to its initial state, thus being inserted into the face mask assembly 1. Specifically, Figure 1 The F1 direction shown is the insertion direction.

[0056] Optionally, the mounting component 21 is made of an elastic material, such as plastic. Alternatively, the mounting component 21 has an elastic structure that absorbs deformation so that the mounting component 21 can switch between an initial state and a deformed state.

[0057] Optionally, when pressure is applied, the connecting end 211 is in a deformed state. When the pressure is released, the connecting end 211 returns to its initial state. This design allows installers to change the state of the connecting end 211 simply by pressing it with their hands without using tools. Furthermore, after the pressure is released, the connecting end 211 tends to automatically return to its initial state. Therefore, when installing the display component 2, installers only need to press the connecting end 211 and insert it into the face mask component 1 along its height direction, and then release the pressure. This embodiment provides a quick and simple installation method that requires neither equipment nor specialized skills.

[0058] Combination Figure 3 and Figure 5 As shown, the connecting end 211 has at least one first connecting portion 2111. The mask assembly 1 has at least one second connecting portion 11. The first connecting portion 2111 and the second connecting portion 11 are correspondingly provided. When the connecting end 211 is inserted into the mask assembly 1, the first connecting portion 2111 and the second connecting portion 11 are engaged.

[0059] The first connecting part 2111 and the second connecting part 11 are engaged to securely fix the mask assembly 1 and the display assembly 2, preventing the display assembly 2 from falling off. Simultaneously, when the connecting end 211 is subjected to a force of a set direction and magnitude—specifically, when the installer pulls the connecting end 211 along the height direction of the mask assembly 1—the engagement is broken, allowing for quick disassembly and significantly reducing the difficulty of later maintenance.

[0060] Combination Figure 6 As shown, the connecting end 211 includes two opposing connecting plates 2112. A gap space is formed between the two opposing connecting plates 2112. At least one of the two connecting plates 2112 is provided with at least one first connecting portion 2111. When at least one connecting plate 2112 is compressed, the connecting end 211 is in a deformed state, and the compressed connecting plate 2112 moves towards the opposing connecting plate 2112. The gap space can absorb the deformation of the connecting plate 2112. The form of the connecting end 211 as a connecting plate 2112 can fully utilize the principle that plates have different rigidity characteristics within different scale ranges. Installers can easily induce a deformed state by pressing the connecting plate 2112.

[0061] Optionally, one end of the first connecting part 2111 is connected to the connecting plate 2112, and the other end of the first connecting part 2111 extends toward the second connecting part 11.

[0062] Optionally, the connecting plate 2112 extends in a direction parallel to the height direction of the mask assembly 1.

[0063] Optionally, the pressure direction of the connecting plate 2112 is perpendicular to the large surface of the connecting plate 2112.

[0064] When the connecting end 211 is pressed by a connecting plate 2112, the connecting end 211 is in a deformed state, and the pressed connecting plate 2112 moves toward the other connecting plate 2112 opposite to it, and also deforms toward the side where the geometric center line along the length direction of the mask assembly 1 is located.

[0065] When both connecting plates 2112 are under pressure, the connecting end 211 is in a deformed state, and both connecting plates 2112 move relative to each other and deform toward the side where the geometric center line along the length direction of the mask assembly 1 is located.

[0066] Optionally, combined Figure 3 As shown, both connecting plates 2112 are provided with a plurality of first connecting parts 2111, and the plurality of first connecting parts 2111 on each connecting plate 2112 are spaced apart along a first direction.

[0067] The preferred direction is the extension direction of the connecting plate 2112, which is also the height direction of the mask assembly 1. This configuration improves the connection stability between the display assembly 2 and the mask assembly 1.

[0068] Combination Figure 4 As shown, the connecting end 211 is an annular thin-walled structure, and at least one first connecting portion 2111 is provided on the outer wall of the thin-walled structure. When at least one part of the outer wall of the thin-walled structure is pressed, the connecting end 211 is in a deformed state, and the pressed part of the outer wall is recessed towards the central axis of the thin-walled structure. Due to the use of an annular thin-walled structure, the structure of the connecting end 211 is simpler and easier to manufacture; furthermore, it facilitates pressing the connecting end 211 by personnel, improving operational convenience.

[0069] Optionally, one end of the first connecting portion 2111 is connected to the outer wall of the thin-walled structure, and the other end of the first connecting portion 2111 extends radially outward along the connecting end 211.

[0070] Combination Figure 1 and Figure 6 As shown, the mask assembly 1 is provided with an installation space 12. When the connecting end 211 is connected to the mask assembly 1, at least one of the first connecting part 2111 and the second connecting part 11 is located within the installation space 12.

[0071] The installation space 12 allows at least part of the connection end 211 to be hidden. Compared to other connection solutions, its connection limiting part is located inside the faceplate assembly 1, which is more aesthetically pleasing. At the same time, it can reduce the overall size of the device, improve the integration of home appliances, and avoid taking up too much indoor space.

[0072] Combination Figure 5 As shown, optionally, the mask assembly 1 includes a mask body 13. The mask body 13 has a mounting hole 131. The mounting hole 131 forms a mounting space 12. At least one second connecting portion 11 is provided on the sidewall of the mounting hole 131. The second connecting portion 11 is correspondingly provided with a first connecting portion 2111. The first end of the second connecting portion 11 is connected to the sidewall of the mounting hole 131, and the second end of the second connecting portion 11 extends toward the corresponding first connecting portion 2111. This arrangement improves the connection stability between the mask body 13 and the connecting end.

[0073] Optionally, the structure of the mounting hole 131 is adapted to the structure of the connecting end 211. That is, when the connecting end 211 includes two opposing connecting plates 2112, the mounting hole 131 is preferably a directional groove structure. When the connecting end 211 includes an annular thin-walled structure, the mounting hole 131 is preferably a cylindrical groove structure.

[0074] Optionally, the size of the mounting hole 131 is slightly larger than the size of the connecting end 211, through which the display component 2 is pushed into the face mask component 1. Preferably, two sets of second connecting parts 11 are provided on the side wall of the mounting hole 131, which, after cooperating with the two sets of first connecting parts 2111 on the connecting end 211, fix the display component to the face mask component. Using the above solution, the structure is simple, the manufacturing cost is low, the installation is quick and convenient, saving installation costs and improving installation efficiency.

[0075] In an optional embodiment, the mask body is provided with mounting holes 131. By pinching two opposing connecting plates 2112, the display component 2 is pushed into the mask component 1 through the mounting holes 131. The inner sidewall of the mask component 1 is provided with a plurality of second connecting parts, which cooperate with a plurality of first connecting parts on the connecting plates 2112.

[0076] Furthermore, when the first connecting portion 2111 is a protruding structure, the second connecting portion 11 corresponding to the first connecting portion 2111 is a grooved structure. When the first connecting portion 2111 is a grooved structure, the second connecting portion 11 corresponding to the first connecting portion 2111 is a protruding structure. When the first connecting portion 2111 is a protruding structure, the second connecting portion 11 corresponding to the first connecting portion 2111 is a flanged structure, so that the protruding structure and the flanged structure overlap.

[0077] It should be noted that the protrusion structures in this embodiment may be the same or different. Similarly, the groove structures in this embodiment may be the same or different.

[0078] Specifically, such as Figure 6 As shown, the end of the connector 211 furthest from the display has two opposing first connecting portions 2111 (shown as protruding structures, specifically as snap-fit ​​structures), which are respectively located on two connecting plates 2112. The mask body 13 has two second connecting portions 11 (both shown as recessed structures) at positions corresponding to the two first connecting portions 2111. Figure 6 As shown, the end of the connector 211 closer to the display has two opposing first connectors 2111 (shown as protruding structures, specifically as snap-fit ​​structures), and the two first connectors 2111 are respectively disposed on the two connector plates 2112. The mask body 13 has two second connectors 11 (shown as flanged structures) at the positions corresponding to the two first connectors 2111.

[0079] Combination Figure 8 As shown, the display 22 further includes a display base 221 and a control circuit board 222. The display base 221 is connected to the first end of the mounting member 21, and a receiving cavity 2211 is provided inside the display base 221. The control circuit board 222 is located inside the receiving cavity 2211.

[0080] Through the above settings, the display base 221 can provide waterproof and dustproof protection for the control circuit board 222. If the display base 221 is made of special materials, it can also provide electromagnetic protection for the control circuit board 222.

[0081] Optionally, the two connecting plates 2112 are symmetrically arranged about the geometric center of the display base 221. When the connecting end 211 is an annular thin-walled structure, the geometric center of the display base 221 is located on the central axis of the connecting end 211.

[0082] Combination Figure 9 As shown, further, a wire-passing hole 223 is provided on the display base 221 near the connection end 211. A wire-passing space is formed inside the connection end 211. The wire-passing hole 223 communicates with the wire-passing space. This arrangement allows the connection end 211 to guide and protect the wire harness, avoiding the risk of short circuits caused by wire tangling or exposed wires.

[0083] Optionally, the two connecting plates 2112 are respectively connected to the two sides of the wire hole 223.

[0084] Optionally, the wire through hole 223 is a square hole. The wire through hole 223 is used to bring out the connection harness of the control circuit board 222.

[0085] Combination Figure 8 As shown, the display 22 further includes a display panel 224. The display panel 224 is located within the receiving cavity 2211 and is situated on the side of the control circuit board 222 away from the connection end 211. The display panel 224 is electrically connected to the control circuit board 222. Through this arrangement, the display panel 224 is effectively fixed, and the display base 221 also provides protection for the display panel 224, preventing the intrusion of external dust or water droplets.

[0086] Furthermore, the display 22 includes a mounting cover 225. The mounting cover 225 is located on the side of the display surface 224 away from the connection end 211, and is connected to the display base 221 to seal the receiving cavity 2211. This arrangement improves the sealing performance of the receiving cavity 2211, protects the relevant electronic components inside the display 22, and extends the service life of the display 22.

[0087] Combination Figure 7 As shown, the mounting cover 225 is further provided with a first thread 2251, and the display base 221 is provided with a second thread 2212. The first thread 2251 and the second thread 2212 are configured to mesh. The thread meshing improves the connection strength between the mounting cover 225 and the display base 221 and reduces the connection difficulty.

[0088] The display base 221 and the mounting cover 225 are both circular in shape, and they are fixed together by tightening the first thread 2251 and the second thread 2212 on the sides of both.

[0089] According to another specific embodiment of the present invention, a ceiling electrical appliance is provided, including a mask device, which is the mask device in the above embodiment.

[0090] Specifically, ceiling-mounted electrical appliances include: air conditioners, bathroom heaters, ventilation fans, range hoods, fresh air systems, and lighting fixtures.

[0091] From the above description, it can be seen that the embodiments of this utility model achieve the following technical effects: A face mask device is provided, in which the face mask assembly and the display assembly can be quickly assembled and disassembled. The display assembly is fixed to the face mask assembly via a first connecting part on the mounting component. During product installation, the face mask assembly and the surrounding fasteners can be fixed first, and then the display assembly can be pushed into the pre-reserved installation space (such as an installation gap) on the face mask. After being pushed into the installation space, the display assembly is fastened to the relevant structure of the face mask assembly via the first connecting part on the mounting component, and the display assembly can be installed on the face mask assembly. The operation is simple, convenient, and reliable. For subsequent after-sales maintenance, it is not necessary to remove the face mask separately; simply pull the display assembly vertically downwards from the face mask to remove it for display-related maintenance operations.

[0092] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.
