Abstract
Description
Technical Field
[0001] This invention relates to a linear indoor heater (especially a bathroom heater) and its installation structure. Background Technology
[0002] Ceiling installation is an essential part of home renovation. Currently, the market offers various ceiling options, including integrated aluminum ceiling panels, plaster ceilings, wood panel ceilings, PVC strip ceilings, and honeycomb panel ceilings. Currently, indoor heaters can only be installed on integrated aluminum ceiling panels; other types of ceilings cannot be directly installed, or require additional adapter frames and access panels for installation. As a result, many users purchase heaters but cannot install them. Summary of the Invention
[0003] This invention was made to solve the above-mentioned technical problems and other potential technical problems.
[0004] One aspect of the present invention provides a linear indoor heater, the indoor heater being generally rectangular in shape and suitable for mounting on a bracket, the indoor heater comprising:
[0005] - A housing, the housing including a first sidewall and a second sidewall opposite to each other, with openings formed in the first sidewall and the second sidewall; and
[0006] - A panel, which is disposed at the bottom of the housing;
[0007] The indoor heater is characterized in that it further includes a screw and a mounting tongue. The screw passes through the mounting tongue and is rotatably connected to the housing, and is capable of rotating the mounting tongue around the screw by an angle and moving it a distance along the screw. When the indoor heater is in an uninstalled or pending installation state, the end of the mounting tongue is located inside the housing or close to the first and second sidewalls. When the indoor heater is in the process of installation or after installation, the mounting tongue rotates around the screw by an angle under the drive of the screw, causing the end to protrude from the opening, and moves a distance along the screw to clamp the bracket using the end and the panel.
[0008] Preferably, the screw includes a threaded rod and a nut fixed to one end of the threaded rod. The nut can be engaged with an external tool for turning. A threaded hole is provided on the mounting tongue, and the other end of the threaded rod can be screwed into and through the threaded hole, so that the rotation of the screw can drive the mounting tongue to rotate and move.
[0009] Preferably, the opening is generally L-shaped and includes a first limiting edge and a second limiting edge. The first limiting edge extends perpendicular to the threaded rod body, and the second limiting edge extends parallel to the threaded rod body. Starting from the uninstalled state or the to-be-installed state, the installation tongue rotates under the drive of the screw, and at the same time, the end moves along the first limiting edge until it abuts against the second limiting edge, and then moves along the second limiting edge until it abuts against the bracket.
[0010] Preferably, the indoor heater further includes a screw cover plate which is fixed on the housing and located outside the screw to prevent the screw from falling off.
[0011] Preferably, a swinging blade and a return air hole are provided on the panel, and the swinging blade can be deflected manually or automatically to allow an external tool to reach the nut.
[0012] Preferably, when the installation tongue moves along the screw to the position closest to the panel, the end of the installation tongue is 16 mm away from the panel. When the installation tongue moves along the screw to the position farthest from the panel, the end of the installation tongue is 52 mm away from the panel.
[0013] Preferably, the linear indoor heater is a ceiling heater.
[0014] Another aspect of the present invention provides an installation structure for a linear indoor heater, including a ceiling or a suspended ceiling, in which a rectangular installation hole is provided, and the installation hole has opposing side edges capable of bearing weight.
[0015] It is characterized in that the installation structure further includes the linear indoor heater according to any one of the foregoing claims. Starting from the uninstalled state or the to-be-installed state, the housing of the linear indoor heater can be embedded into the installation hole. By using an external tool to twist the screw, the installation tongue rotates around the screw by an angle under the drive of the screw, and the end extends out of the opening, and moves a distance along the screw, so as to clamp the side edge by the end and the panel.
[0016] Preferably, the installation structure satisfies: w1 < w3 < w2, and l1 < l3 < l2, where w1 is the width of the housing, w2 is the width of the panel, w3 is the width of the installation hole, l1 is the length of the housing, l2 is the length of the panel, and l3 is the length of the installation hole.
[0017] Preferably, the installation structure satisfies: h min < h < h max where h is the thickness of the side edge. h minThis refers to the distance from the end of the mounting tongue to the panel when the mounting tongue moves along the screw to its closest position to the panel. max It is the distance from the end of the mounting tongue to the panel when the mounting tongue moves along the screw to the position furthest from the panel.
[0018] Preferably, h min =16mm, and h max =52mm.
[0019] Optionally, the ceiling includes side-by-side joists, and the sidewalls are formed by adjacent joists.
[0020] By adopting the linear indoor heater and its installation structure of the present invention, users only need to open a mounting hole in the ceiling to complete the installation, without the need for an additional conversion frame or access panel. Attached Figure Description

[0036] Next, refer to Figures 1A to 2F To describe an embodiment of an indoor heater according to the present invention, the indoor heater may be a linear bathroom heater.

[0037] like Figures 1A to 2F As shown, the linear indoor heater 100 according to the present invention is generally rectangular in shape and is suitable for installation as described below. Figures 3A to 4C The brackets 23, 25, 33, and 35 are described. The indoor heater 100 includes a housing 1 and a panel 3 disposed at the bottom of the housing 1. The housing 1 includes a first sidewall 1a and a second sidewall 1b opposite to each other. At least one opening 11 is formed in the first sidewall 1a and the second sidewall 1b. This embodiment includes two openings 11.1 and 11.2, and it is understood that other embodiments may include more openings 11.
[0038] The linear indoor heater 100 of the present invention is characterized in that it further includes screws 15.1 and 15.2 and corresponding mounting tongues 13.1 and 13.2. The screws 15.1 and 15.2 respectively pass through the mounting tongues 13.1 and 13.2 and are rotatably connected to holes 1c and 1d at the bottom of the housing 1, and are capable of driving the corresponding mounting tongues 13.1 and 13.2 to rotate by an angle about the screws 15.1 and 15.2 and to move a distance along the screws 15.1 and 15.2.
[0039] like Figure 1C and Figure 2C As shown, taking the mounting tongue 13.2 as an example, the mounting tongue 13.2 is generally strip-shaped and has two ends 13.2a and 13.2b. A threaded hole 13.2c is provided in the middle of the mounting tongue 13.2. The other end (upper end) of the threaded rod 15.2a can be screwed into and pass through the threaded hole 13.2c, so that the rotation of the screw 15.2 can drive the mounting tongue 13.2 to rotate and move.
[0040] Taking screw 15.2 as an example, screw 15.2 includes a threaded shank 15.2a and a nut 15.2b located at one end (lower end) of the threaded shank 15.2a. The nut 15.2b can engage with an external tool (e.g., a screwdriver) 19 so that it can be turned by the external tool 19, for example, clockwise or counterclockwise in the direction shown by arrow B. The case of screw 15.1 is similar to that of screw 15.2, and will not be described again here.
[0041] The indoor heater 100 also includes screw cover plates 17.1 and 17.2. Screw cover plates 17.1 and 17.2 are fixed to the housing 1 and are located outside the screws 15.1 and 15.2, respectively, particularly below the screws 15.1 and 15.2. Taking screw cover plate 17.2 as an example, screw cover plate 17.2 has connecting holes 17.2a and 17.2b at both ends and a through hole 17.2c at the center. Screw cover plate 17.2 is fixed to the housing 1 by rivets or screws (not shown) passing through the connecting holes 17.2a and 17.2b. The diameter of the through hole 17.2c is smaller than the diameter of the nut 15.2b but larger than the diameter of the external tool 19. This allows the external tool 19 to pass through the through hole 17.2c to turn the screw 15.2 while preventing the screw 15.2 from falling out through the through hole 17.2c. The situation of screw cover 17.1 is similar to that of screw cover 17.2, and will not be described again here.
[0042] In addition, such as Figure 1A and Figure 1B As shown, a swivel blade 5 and a return air vent 7 are provided on panel 3. The swivel blade 5 can move along the airflow path as shown in the diagram. Figure 1B The direction indicated by arrow A is manually or automatically deflected to allow external tools 19 to access nuts 15.1b and 15.2b. Specifically, during the installation of the indoor heater 100, the installer can use their fingers to turn the edge 9 of the oscillating blade 5 so that the oscillating blade 5 moves along the direction indicated by arrow A. Figure 1B The blade 5 deflects in the direction indicated by arrow A and eventually reaches a vertical position 5'. This allows the external tool 19 to access the nut 15.2b without obstruction. It should be understood that after installation is complete and the external tool 19 is removed, the blade 5 can be manually deflected to the normal position, or the blade 5 can automatically return to the normal position after the indoor heater 100 is powered on.
[0043] like Figures 2A to 2F As shown, to more clearly describe the structure of mounting tongues 13.1 and 13.2, mounting tongue 13.1 is shown in an uninstalled or pending installation state, while mounting tongue 13.2 is shown in the process of installation or completed installation state. Specifically, in the uninstalled or pending installation state, the ends 13.1a and 13.1b of mounting tongue 13.1 are located inside the housing 1, or respectively abutting against the first sidewall 1a and the second sidewall 1b. During installation, mounting tongue 13.1 is driven by screw 15.1 to rotate around screw 15.1 (specifically, along... Figure 2B The arrow (in the direction indicated by F) is rotated by an angle so that ends 13.1a and 13.1b protrude from opening 11.1. It should be understood that the direction indicated by arrow F here is different from that described later. Figure 3B and Figure 4BThe direction indicated by arrow F in the diagram is consistent. Finally, mounting tongue 13.1 is positioned as shown in the figure for mounting tongue 13.2. At this point, the distances from the ends 13.1a, 13.1b, 13.2a, and 13.2b of mounting tongues 13.1 and 13.2 to panel 3 are at their maximum values, h. max In this embodiment, for example, h max =52mm.
[0044] Openings 11.1 and 11.2 are generally L-shaped. Taking opening 11.1 as an example, opening 11.1 includes a first limiting edge 11.1a and a second limiting edge 11.1b. The first limiting edge 11.1a extends perpendicularly to the threaded rod of the screw 15.1, and the second limiting edge 11.1b extends parallel to the threaded rod of the screw 15.1 (see description below). Figures 3B to 3D ).
[0045] Taking the mounting tongue 13.1 as an example, starting from the uninstalled or pending installation state, the mounting tongue 13.1 rotates in the direction indicated by arrow F under the drive of screw 15.1, while its end 13.1a moves along the first limiting edge 11.1a of opening 11.1 until it abuts against the second limiting edge 11.1b of opening 11.1. At this point, the mounting tongue 13.1 cannot continue to rotate in the direction indicated by arrow F due to being blocked by the second limiting edge 11.1b.
[0046] Then, as the screw 15.1 rotates further, the mounting tongue 13.1 moves along the second limiting edge 11.1b until it abuts against the brackets 23, 25 (see later). Figure 3C and Figure 3D , Figure 3F and Figure 3G (Description). When the mounting tongue 13.1 moves along the screw 15.1 to the position closest to the panel 3, the distance between the ends 13.1a and 13.1b of the mounting tongue 13.1 and the panel 3 is the minimum value h. min In this embodiment, for example, h min =16mm. In other words, the installation structure of the indoor heater 100 of the present invention satisfies: h min <h<h max Where h is the thickness of the side edges 23 and 25. The installation of tongue 13.2 is similar to that of tongue 13.1, and will not be described again here.
[0047] Next, refer to Figures 3A to 3G An embodiment of the process of installing an indoor heater according to the present invention onto the ceiling is described. Figures 3A to 3D They are respectively to Figure 1A The diagram shows the steps for installing an indoor heater onto the ceiling, and... Figures 3B to 3D The right side of each shows a magnified view; Figure 3E is Figure 1A a cross-sectional view of the indoor heater shown when in the installation steps as Figure 3B shown; Figure 3F is Figure 1A a cross-sectional view of the indoor heater shown when in the installation steps as Figure 3C shown; Figure 3G is Figure 1A a cross-sectional view of the indoor heater shown when in the installation steps as Figure 3D shown.
[0048] As Figure 3A shown, a rectangular installation hole 21 is formed in the ceiling 200. The installation hole 21 has opposing side edges 23, 25 capable of bearing weight. The installation structure of the linear indoor heater according to the present invention satisfies: w1 < w3 < w2, and l1 < l3 < l2, where, w1 is the width of the housing 1, w2 is the width of the panel 3, w3 is the width of the installation hole 21, l1 is the length of the housing 1, l2 is the length of the panel 3, and l3 is the length of the installation hole 21 (see also Figure 2B ). The installation process of the indoor heater 100 according to the present invention is as follows:
[0049] 1. Starting from the uninstalled state or the to-be-installed state mentioned above, move the housing 1 of the indoor heater 100 in the direction shown by the arrow G and embed it into the installation hole 21, as Figure 3A and Figure 3E shown.
[0050] 2. As Figure 3B shown, by means of an external tool (not shown) 19, twist the screw 15.1. The installation tongue 13.1 rotates around the screw 15.1 by an angle under the drive of the screw 15.1, so that the end 13.1a moves along the first limiting edge 11.1a in the direction shown by the arrow F and extends out from the opening 11. , until it abuts against the second limiting edge 11.1b of the opening 11.1, as Figure 3C and Figure 3F shown. At this time, the installation tongue 13.1 cannot continue to rotate in the direction shown by the arrow F due to being blocked by the second limiting edge 11.1b. The installation of the end 13.1b is similar to that of the end 13.1a and will not be elaborated here.
[0051] 3. As the screw 15.1 rotates further, the installation tongue 13.1 moves along the second limiting edge 11.1b in the direction shown by the arrow H until the end 13.1a abuts against the upper surface 23a of the side edge 23, as Figure 3D and Figure 3GAs shown. At this time, the side 23 is clamped by using the end 13.1a and the panel 3. The installation of the end 13.1b is similar to that of the end 13.1a, except that the end 13.1b abuts against the upper surface 25a of the side 25, and together with the panel 3, clamps the side 25. Details are not described herein again.
[0052] 4. The installation of the installation tongue 13.2 is similar to that of the installation tongue 13.1, and details are not described herein again.
[0053] The installation structure of the linear indoor heater according to the present invention satisfies: h min <h < h max , where h is the thickness of the sides 23 and 25. h min is the distance from the ends 13.1a, 13. – 1b, 13.2a, 13.2b of the installation tongues 13.1, 13.2 to the panel 3 when the installation tongues 13.1, 13.2 move along the screws 15.1, 15.2 to the position closest to the panel 3. h max is the distance from the ends 13.1a, 13.1b, 13.2a, 13.2b of the installation tongues 13.1, 13.2 to the panel 3 when the installation tongues 13.1, 13.2 move along the screws 15.1, 15.2 to the position farthest from the panel 3. In this embodiment, for example, h min = 16 mm, and for example, h max = 52 mm.
[0054] Next, an embodiment of the process of installing the indoor heater according to the present invention onto the ceiling is described with reference to Figures 4A to 4C . Figures 4A to 4C respectively show the schematic diagrams of the steps of installing the Figure 1A shown indoor heater onto the ceiling.
[0055] As Figure 4A shown, the ceiling 300 includes parallel keels, and the opposed sides 33, 35 are formed by a part or all of adjacent keels, and the sides 33, 35 respectively have upper surfaces 33a, 35a. The indoor heater 100 is adapted to be installed in the gap 31 between the sides 33, 35. The installation structure of the linear indoor heater according to the present invention satisfies: w1 < w4 < w2, where w1 is the width of the housing 1, w2 is the width of the panel 3, and w4 is the width of the gap 31 (see also Figure 2B ). The process of installing the indoor heater 100 onto the ceiling 300 is similar to the process of installing the indoor heater 100 onto the ceiling 200 described above:
[0056] 1. Starting from the uninstalled state or the to - be - installed state mentioned above, move the housing 1 of the indoor heater 100 in the direction shown by the arrow G and embed it into the gap 31, as Figure 4AAs shown.
[0057] 2. For example Figure 4B As shown, by using an external tool 19 (not shown), the screw 15.1 is turned, causing the mounting tongue 13.1 to rotate around the screw 15.1 by an angle. This causes the end 13.1a to move along the first limiting edge 11.1a in the direction indicated by arrow F and extend out of the opening 11.1 until it abuts against the second limiting edge 11.1b of the opening 11.1. At this point, the mounting tongue 13.1 cannot continue to rotate in the direction indicated by arrow F due to the obstruction of the second limiting edge 11.1b. The installation of the end 13.1b is similar to that of the end 13.1a and will not be described again here.
[0058] 3. For example Figure 4C As shown, as the screw 15.1 rotates further, the mounting tongue 13.1 moves along the second limiting edge 11.1b in the direction indicated by arrow H until the end 13.1a abuts against the upper surface 33a of the side 33. At this time, the side 33 is clamped by the end 13.1a and the panel 3. The installation of the end 13.1b is similar to that of the end 13.1a, except that the end 13.1b abuts against the upper surface 35a of the side 35 and clamps the side 35 together with the panel 3, which will not be described in detail here.
[0059] 4. The installation of the tongue piece 13.2 is similar to that of the tongue piece 13.1, and will not be described again here.
[0060] By adopting the linear indoor heater and its installation structure of the present invention, users only need to drill a single installation hole in the ceiling / suspended ceiling to complete the installation. No additional conversion frame or access panel is required, thereby reducing the complexity of manufacturing and installation and saving time and economic costs.
[0061] Although the technical solution of the present invention has been described above using a linear indoor heater (such as a linear bathroom heater) as an example, it is conceivable that the technical solution of the present invention is also applicable to indoor fresh air systems, central air conditioning, HVAC systems, etc.
[0062] Although the technical objectives, solutions, and effects of the present invention have been described in detail above with reference to specific embodiments, it should be understood that the above embodiments are merely exemplary and not restrictive. Any modifications, equivalent substitutions, or improvements made by those skilled in the art within the essential spirit and principles of the present invention are included within the scope of protection of the present invention.
