Description

Technical Field

[0001] The utility model relates to the field of electrical appliances, and in particular to a shell assembly and a ceiling-mounted electrical appliance having the shell assembly. Background Art

[0002] In the prior art, some ceiling appliances (such as bathroom heaters, air conditioners, ventilation fans, etc.) have special design structures. Due to their unique structural limitations, they cannot be installed after the ceiling panels are installed. The ceiling appliance host can only be installed first and then the ceiling panels (such as gypsum boards and large boards). In addition, this installation sequence determines that the ceiling appliance can only be suspended on the ceiling, which has the defect of inconvenient installation.

[0003] For example, the linear bathroom heater's mask is long and narrow. This unique design structure has the advantage of an aesthetically pleasing appearance and is popular with users. However, because the ceiling panel only has a through-hole that matches the mask's size (the narrow size prevents the bathroom heater's main unit from passing through the through-hole into the mezzanine space formed by the ceiling panel and the ceiling), it is impossible to install the ceiling panel first and then the linear bathroom heater. The linear bathroom heater must be suspended from the ceiling before installing the ceiling panel. This solution has the disadvantage of being inconvenient to install and may even be impossible to install in some scenarios.

[0004] With respect to the above-mentioned problems in the prior art, no effective solution has been proposed yet.

[0005] Furthermore, due to the low distance between the ceiling panel and the ceiling, the size of the chassis shell of the ceiling appliance is limited, which in turn limits the size of the fan of the ceiling appliance, making it impossible to ensure that the air volume of the ceiling appliance meets the usage requirements. Utility Model Content

The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0049] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in a variety of different forms and should not be interpreted as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of this application thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art. In the accompanying drawings, for the sake of clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to represent the same devices, and thus their descriptions will be omitted.

[0050] Currently, more and more indoor ceiling solutions use large-panel or gypsum board ceilings. This type of ceiling solution has the advantages of more beautiful appearance and convenient installation. However, this type of ceiling solution can make the installation of some ceiling-mounted appliances with special structures inconvenient or even impossible.

[0051] For example, a linear bathroom heater, a ceiling-mounted appliance, has a long, narrow faceplate and a narrow air outlet. Ceiling panels typically have mounting holes that are smaller than or equal to the faceplate or air outlet width. Consequently, the mounting holes are too small to fit the main housing of the bathroom heater.

[0052] Therefore, the linear heater must be installed first and then the ceiling panels. This makes linear heater installation extremely inconvenient. For example, if a ceiling structure is already installed, the entire ceiling structure must be dismantled before installing this linear heater, resulting in a cumbersome process and increased costs.

[0053] At the same time, further, due to the low distance between the ceiling panel and the ceiling, the chassis shell size of the ceiling appliance is limited, which in turn limits the fan size of the ceiling appliance, and cannot ensure that the air volume of the ceiling appliance meets the usage requirements.

[0054] The above problems restrict the application of ceiling appliances such as linear bathroom heaters and linear air conditioners, and those skilled in the art have not yet proposed an effective solution.

[0055] Combine Figures 1 to 19 As shown, according to a specific embodiment of the present application, a housing assembly is provided.

[0056] The shell assembly 10 includes: a shell unit 11, there are at least two shell units 11, the shell units 11 have an assembly position for being assembled along a preset direction to form the shell assembly 10, and each shell unit 11 has a disassembly position separated from each other, wherein the thickness of the shell unit 11 is less than the width of the ceiling through hole, so that the shell unit 11 can enter the ceiling space through the ceiling through hole, and the preset direction is the thickness direction of the shell assembly 10.

[0057] By applying the technical solution of the present invention, the shell assembly 10 is set to at least two shell units 11, and the shell unit 11 has an assembly position and a disassembly position, so that the shell assembly 10 can be divided into multiple shell units with smaller thickness along the thickness direction. The shell units can enter the ceiling space through the ceiling through holes, thereby removing the installation restrictions of the installation environment on the shell assembly 10, so that the ceiling appliances can be installed after the ceiling structure is installed, effectively solving the problem of inconvenience in installing ceiling appliances in the prior art.

[0058] For example, the thickness of the shell assembly 10 is Amm. By dividing the shell assembly 10 into three shell units 11, the thickness of each shell unit 11 is 1 / 3*Amm. Each shell unit 11 can enter the mezzanine space through a narrow through hole on the ceiling structure and be assembled in the mezzanine space to form an integral shell assembly 10, thereby eliminating the need to install the shell assembly or destroy the ceiling structure before installing the ceiling.

[0059] The shell assembly 10 refers to the main body shell and internal structure of the ceiling appliance. For example, in some embodiments, the ceiling appliance is a bathroom heater. The shell assembly 10 includes the main body shell and its internal main power components (such as the fan part), the air duct structure (used to guide the airflow driven by the power component to move along a preset path), the heating device (such as PTC), etc. The ceiling through-hole is a hole opened on the ceiling large board or gypsum board. The ceiling appliance can be installed through the ceiling through-hole. The mask of the ceiling appliance can be connected to the main body or the ceiling through the ceiling through-hole. The shell unit 11 refers to the sub-shell formed by dividing the shell assembly 10 along the thickness direction, which is used to install and protect the internal components or form the air duct or internal structural parts of the ceiling appliance. The internal components of different shell units 11 can be different or the same. When the shell units 11 are assembled together, the components inside the shell units 11 work together again to complete the various work tasks of the ceiling appliance.

[0060] Furthermore, when the housing unit 11 is located at the assembly position, the housing unit 11 is completely located in the ceiling space.

[0061] The ceiling space refers to the interlayer space formed between the ceiling structure and the ceiling. When each housing unit 11 is completely located in the interlayer space, the housing units 11 can be assembled in the assembly position to form a complete housing assembly 10, ensuring the normal use of the ceiling appliance.

[0062] Furthermore, at least part of the shell unit 11 is located outside the ceiling space, which includes the following two situations: 1. When the shell unit 11 is completely outside the ceiling space, the shell unit 11 needs to be separated from other shell units 11 and prepared for installation; 2. The shell unit 11 is partially located in the ceiling space and partially located outside the ceiling space. At this time, the shell unit 11 is entering the mezzanine space through a narrow hole in the ceiling structure. At this time, it is also necessary to ensure that the shell units 11 are in a state of separation from each other.

[0063] like Figure 13 and Figure 16 As shown, when the housing unit 11 is in the assembled position, at least one housing unit 11 is connected to the mounting base, so that the mounting base supports at least a portion of the housing assembly 10. The housing assembly 10 provided in this embodiment can be hoisted and / or supported by the mounting base, and the mounting base can have a larger contact area with the housing assembly 10, thereby improving the connection stability of the housing assembly 10 and ensuring its reliable connection.

[0064] Furthermore, the installation base is a ceiling board or a gypsum board.

[0065] Furthermore, the shell assembly 10 has a first air outlet 12, which is parallel to the thickness direction of the shell assembly 10. When the shell unit 11 is in the assembly position, the thickness direction of the shell assembly 10 is parallel to the horizontal direction, so that the projection of the first air outlet 12 along the horizontal plane at least partially overlaps with the projection of the ceiling through hole along the horizontal plane.

[0066] Furthermore, the shell assembly 10 has a first air outlet 12, which is parallel to the length direction of the shell assembly 10. When the shell unit 11 is in the assembly position, the thickness direction of the shell assembly 10 is perpendicular to the horizontal direction, so that the projection of the first air outlet 12 along the horizontal plane at least partially overlaps with the projection of the ceiling through hole along the horizontal plane.

[0067] In one embodiment, Figures 8-13 The figure shows the installation steps of a bathroom heater with the first air outlet 12 parallel to the length direction of the shell assembly 10. The figure shows a large plate 30 (the large plate 30 can also be replaced by a gypsum ceiling). The installation steps include:

[0068] 1. Install the first housing unit 11 through the hole in the ceiling plate into the mezzanine space (such as Figure 9 2. Place the housing unit 11 installed into the mezzanine space clockwise (as shown); Figure 10 3. Install the second housing unit 11 through the hole on the ceiling plate into the mezzanine space (as shown); Figure 12 4. Turn the second housing unit 11 installed into the mezzanine space clockwise (as shown); Figure 13 as shown) and assemble.

[0069] In one embodiment, Figure 14-16 It shows the installation steps of the bathroom heater in which the first air outlet 12 is parallel to the thickness direction of the shell assembly 10.

[0070] The installation steps are as follows: 1. Install the first housing unit 11 into the mezzanine space through the hole in the ceiling plate (such as Figure 14 2. Move the first housing unit 11 to one side in the mezzanine and install the second housing unit 11 into the mezzanine space through the hole on the ceiling plate (as shown in FIG. Figure 15 3. Assemble the second housing unit 11 installed into the mezzanine space with the previous housing unit 11 (as shown); Figure 16 shown).

[0071] In another optional embodiment, the housing assembly 10 includes a plurality of split fans, and when the two housing units 11 are located at the assembly position, the split fans are spliced together to form a fan assembly.

[0072] Alternatively, a split fan can be installed in one housing unit and follow housing unit 11 into the mezzanine space. Multiple split fans can also be installed in two housing units, with each split fan following its corresponding housing unit 11 into the mezzanine space before assembly. Split fans can also be disconnected from the housing units and assembled by passing through the ceiling holes before or after the housing unit 11 enters the mezzanine space.

[0073] Furthermore, one of the at least two housing units 11 is provided with a fan unit 118, the axial direction of the fan unit 118 being parallel to the thickness direction of the housing assembly 10. The fan unit 118 has an initial state and a stowed state in which the fan unit 118 is compressed a preset distance along its own axial direction. When the fan unit 118 is in the stowed state, the fan unit 118 is completely located within the housing unit 11. When the at least two housing units 11 are in the assembled position, the fan unit 118 is in the initial state, and the impeller 116 of the fan unit 118 extends along its own axial direction into the other housing unit 11. In the present application, the fan unit 118 includes the impeller 116. The fan unit 118 can be a whole unit or can be configured as multiple independent split structures. The split fans in the above-mentioned embodiments are multiple split structures in which the fan unit 118 is located at different positions. By assembling the above-mentioned split fans, the fan unit 118 can be formed to perform the airflow driving function.

[0074] In an optional embodiment, the shell assembly includes two shell units 11, and the two shell units 11 include a first unit and a second unit. A fan part 118 is provided in the first unit, and the central axis direction of the fan part 118 is parallel to the thickness direction of the shell assembly 10. A cavity is formed in the second unit. When the first unit and the second unit are in the assembly position, the fan part 118 includes a fan, and the fan enters the second unit away from one end of the first unit, so that the fan drives the airflow in the air ducts in the two shell units 11 at the same time, thereby increasing the air volume of the ceiling appliance.

[0075] like Figures 2 to 4 As shown, at least one shell unit 11 is provided with: a casing body; a volute side plate 113, the volute side plate 113 is arranged in the casing body, a volute fluid channel 1131 is formed in the volute side plate 113, and an opening is provided on the volute side plate 113; a spliced volute 114, the spliced volute 114 has a working position that is at least partially protruding from the outer surface of the casing body, and when the spliced volute 114 is in the working position, the spliced volute 114 blocks at least part of the opening, and at least part of the spliced volute 114 is located outside the casing body, so that the spliced volute 114 and the volute side plate 113 are surrounded by a separate volute enclosure 115. The spliced volute 114 has a storage position or an assembly position. When the spliced volute 114 is in the storage position, the spliced volute 114 moves along the first direction to the inner side of the casing body or the volute side plate 113. When the spliced volute 114 is in the storage position, the spliced volute 114 is located outside the casing body and is disconnected from the casing body and the volute side plate 113.

[0076] It should be noted that the air duct of a ceiling-mounted appliance primarily consists of two parts: the first being the volute fluid passage 1131 formed by the volute side panels, and the second being the airflow guide structure formed by the remaining panels. This airflow guide structure can, for example, be used to direct airflow toward an outlet or air exchange vent. Together, these two parts form the air duct of the ceiling-mounted appliance.

[0077] Using the technical solution of the above embodiment, the spliced volute 114 can be used to partially expand the air duct. Switching between the working position, the storage position, or the ready-to-assemble position allows the spliced volute 114 to be hidden during the installation of the ceiling appliance without adding any obstacles to the installation process. After the ceiling appliance is installed, it can be returned to the working position to partially expand the air duct.

[0078] like Figure 8 As shown, L1 is 160mm, which corresponds to the height of the mezzanine space. Since the shell unit 11 needs to be placed, the height of the shell unit 11 must be less than 160mm so that clockwise rotation can be achieved. Therefore, the size of the volute in the corresponding shell unit 11 and the fan in the volute will be limited accordingly, thereby affecting its air volume. Through the setting of the spliced volute, the shell unit 11 will not exceed 160mm when it is rotated and installed (the spliced volute is in a hidden position), and after the rotation is completed (the spliced volute is in a working position), the size of the shell unit 11 can be greater than 160mm, thereby removing the size limit of the fan size and increasing the air volume.

[0079] The volute side plate 113 of the volute fluid channel 1131 is arranged in the casing body. The volute fluid channel 1131 can have two structural forms: 1. The volute side plate 113 forms the volute fluid channel 1131 alone, and the bottom plate of the volute side plate 113 is the bottom wall of the volute fluid channel 1131; 2. The volute side plate 113 is set as a plate-like structure, and the volute fluid channel 1131 is enclosed between the volute side plate 113 and the side wall and bottom plate of the shell. It should be noted that for some ceiling-mounted electrical appliances (such as bathroom heaters), the spliced volute 114 in the above embodiment is used. In order to avoid interference with other components during position switching, components such as the wind collecting hood need to be adaptively modified and designed.

[0080] like Figure 3 Two split volute enclosures 115 are shown in FIG. 1 . The split volute enclosures 115 are formed by the spliced volute 114 and the volute side panels 113 in the working position. At least a portion of the split volute enclosures 115 is arc-shaped.

[0081] Furthermore, the spliced volute 114 has a concave cavity on the side facing the volute side plate 113. When the spliced volute 114 is in the working position, the concave cavity is connected to the volute fluid channel 1131 to form at least part of the air duct. An impeller 116 is provided in the shell unit 11, part of the impeller 116 is located in the concave cavity, and at least part of the impeller 116 is located in the volute fluid channel 1131.

[0082] By adopting the technical solution of the above embodiment, the size of the impeller 116 can be made larger, thereby increasing the air volume of the ceiling-mounted electrical appliance.

[0083] In an optional embodiment, the first direction is the width of the housing body. That is, the spliced volute 114 can move along the width of the housing body to a storage position within the housing body or the volute side panels 113. This arrangement can fully utilize the redundant space within the housing body or the volute side panels 113, storing the spliced volute 114 during housing assembly installation and then removing it after housing assembly installation is complete, thereby allowing for installation of a larger fan unit.

[0084] like Figure 3 As shown, each housing unit 11 is provided with a spliced volute 114 . When each housing unit 11 is in the assembly position, the multiple split volute enclosures 115 formed are spliced along the thickness direction of the housing component 10 to form a volute enclosure assembly. Figure 3 2 shows two split volute shrouds 115 , which are spliced along the thickness direction of the shell assembly 10 to form a volute shroud assembly.

[0085] Optionally, the linear bathroom heater is divided into N shell units 11 in the thickness direction. Correspondingly, the volute side panels are also divided into N parts along the thickness direction. Each shell unit 11 forms a portion of the split air duct (specifically, the volute fluid channel 1131). After the multiple shell units 11 are assembled, an integrated air duct is formed. The airtightness design of each split air duct is a conventional design based on actual needs by those skilled in the art and will not be repeated here.

[0086] In the prior art, most dual-fan bathroom heaters use a notch directly in the middle of the housing to form the air outlet. Since the notch is located in the middle of the housing, this arrangement results in a complex air duct structure inside the bathroom heater, leaving insufficient space for an airflow guide structure, resulting in poor airflow performance. To address this issue, the present application proposes a housing assembly with an air guide structure.

[0087] Furthermore, the housing assembly 10 includes a volute side plate 113, which defines at least a portion of a volute fluid passage 1131. The housing assembly 10 also includes an air guide structure 20, which connects the volute fluid passage 1131 and the first air outlet 12. The technical solution of this embodiment allows the airflow within the volute fluid passage 1131 to be directed outward via the air guide structure 20. This not only facilitates the placement of the first air outlet 12 so that it at least partially corresponds to the ceiling through-hole, but also reduces along-the-line losses and noise during airflow movement.

[0088] Furthermore, the housing unit 11 includes a connecting air duct 112 , the connecting air duct 112 is in communication with the volute fluid passage 1131 , and the connecting air duct 112 is in communication with the first air outlet 12 .

[0089] In another optional embodiment, there are two volute side panels 113, and a volute fluid channel 1131 is formed in each of the two volute side panels 113. The shell unit 11 also includes a connecting air duct 112. The two volute fluid channels 1131 are connected to the connecting air duct 112. A first air outlet 12 is provided on the side wall of the connecting air duct 112; and the air guide structure 20 is connected to the connecting air duct 112. By adopting the technical solution in this embodiment, a new structure in which two fans share the connecting air duct 112 is constructed to ensure the air volume of the ceiling electrical appliances. This arrangement allows the air duct assembly to be installed in the ceiling space through the smaller installation opening on the ceiling panel, and the thickness direction of the air duct assembly is the same as the thickness direction of the ceiling panel, and the air flow blown out from at least two volute fluid channels 1131 is gathered into the connecting air duct 112, and then blown out of the shell unit 11. This arrangement helps to optimize the air outlet mode of the air duct assembly and enhance the air supply performance of the air duct assembly.

[0090] Combine Figures 17 to 19 As shown, in this embodiment, the air duct assembly can be applied to a linear bathroom heater. The linear bathroom heater is moved into the ceiling space through the smaller installation opening on the ceiling board along the height direction of the ceiling space, and the thickness direction of the linear bathroom heater located in the ceiling space is placed and installed along the vertical direction of the ceiling space. In order to better achieve the air outlet performance of the air duct assembly after installation, an air guide structure 20 is protrudingly formed on the side wall of the connecting air duct 112. This arrangement allows the airflow blown out from at least two volute fluid channels 1131 to be blown out of the shell unit 11 through the air guide structure 20, simplifying the internal space of the air duct assembly, saving installation space, and making the installation of the air outlet assembly more convenient while optimizing the air outlet method of the air duct assembly, so that the air duct assembly takes into account both practicality and aesthetics.

[0091] In a preferred embodiment of the present application, the air guide structure 20 is integrally provided with the connecting air duct 112. This arrangement makes the installation of the air duct assembly more convenient and improves the practicality of the air duct assembly.

[0092] In another preferred embodiment of the present application, the air guide structure 20 is detachably connected to the side wall of the connecting air duct 112 to facilitate subsequent cleaning, repair, replacement, etc. of the air guide structure 20, thereby saving subsequent maintenance costs.

[0093] Combine Figure 18 As shown, in order to better achieve the wind-guiding performance of the wind-guiding structure 20, in a preferred embodiment of the present application, the wind-guiding structure 20 includes a first side panel 23 and two second side panels 22, and the first side panel 23 is connected to the side wall of the connecting air duct 112; the two second side panels 22 are both connected to the side wall of the connecting air duct 112, the two second side panels 22 are arranged opposite to each other, and the first air outlet 12 is located between the two second side panels 22, and the two second side panels 22, the first side panel 23 and the connecting air duct 112 are surrounded to form a wind-guiding structure with openings on both sides, one of the openings is connected to the first air outlet 12, and an wind-guiding channel is formed between the two openings, so that the air outlet is smoother.

[0094] Furthermore, in a preferred embodiment of the present application, the inner surface of the first side panel 23 is formed with at least a partial curved surface structure. This configuration can reduce wind resistance when the airflow is blown out through the air guide structure 20, thereby optimizing the air outlet performance of the air duct assembly.

[0095] Furthermore, the first side panel 23 includes a first segment 211 and a second segment 212. The first segment 211 is connected to the side wall of the connecting air duct 112, and the second segment 212 is connected to the first segment 211. The two second side panels 22, the first segment 211, the second segment 212, and the connecting air duct 112 form an air guide structure with openings on both sides. This design improves the efficiency and controllability of air flow, while also reducing noise during airflow, improving the user experience.

[0096] In a preferred embodiment of the present application, at least one of the first component segment 211 and the second component segment 212 is a straight plate structure. Such a design helps to achieve the effect of guiding the airflow, improve the air outlet efficiency, and reduce noise.

[0097] In a preferred embodiment of the present application, at least one of the first component segment 211 and the second component segment 212 is a curved plate structure. This design helps to reduce the wind resistance when the air flows through the air guide structure 20, improve the air outlet efficiency, and reduce noise.

[0098] Combine Figure 18 As shown, in a preferred embodiment of the present application, the first component segment 211 is an arc-shaped plate structure, and at least one of the second component segments 212 is a straight plate structure, so as to achieve the effect of guiding the airflow, reduce the wind resistance, and improve the air outlet efficiency.

[0099] The shell unit 11 provides structural support and protects the internal air duct assembly, so that when the shell unit 11 is installed in the ceiling space through a smaller installation opening on the ceiling panel, it helps to achieve a variety of air outlet positions of the air duct assembly, optimize the air outlet method of the air duct assembly, and save installation space, so that the air duct assembly is both practical and beautiful.

[0100] In a specific embodiment of the present application, the air duct assembly can be applied to a linear bathroom heater. The linear bathroom heater is moved into the ceiling space through a smaller installation opening on the ceiling panel along the height direction of the ceiling space. The thickness direction of the linear bathroom heater located in the ceiling space is placed and installed along the vertical direction of the ceiling space. The connecting air duct 112 is provided with a ventilation port 13, which is optionally connected to the connecting air duct 112. In such an installation, when the linear bathroom heater is ventilated, the airflow blown out from at least two volute fluid channels 1131 can be converged to the connecting air duct 112 along the radial direction of the volute fluid channels 1131, and then blown out of the housing unit 11 through the ventilation port 13 along the width direction of the air duct assembly (i.e., the horizontal direction of the ceiling space). This arrangement makes the air duct assembly convenient for indoor and outdoor ventilation, avoids the problem in the prior art that the thickness direction of the linear bathroom heater is along the horizontal direction of the ceiling space, resulting in the ventilation pipe connected to the air outlet needing to be configured as a bendable shape, and optimizes the ventilation performance of the air duct assembly. In an optional embodiment, the fan of the linear bathroom heater is placed vertically (that is, the central axis of the fan is parallel to the horizontal plane). Due to the height limitation of the mezzanine space, the height of the volute and the fan inside the volute is limited, which in turn limits the air volume. The solution to the above problem is to set up an extra fan, so there are usually two fans for indoor air supply (exhaust), and ventilation requires a fan, so the linear bathroom heater has three fans. At the same time, the linear bathroom heater pursues extreme narrowness, and the extremely narrow shape is beautiful, which is loved by users. However, the extremely narrow bathroom heater will make the axial size of the fan smaller, which limits the air supply performance, and adding fans will increase costs.

[0101] To solve the above problems, the shell assembly 10 has a first air outlet 12 and a ventilation port 13. The shell assembly 10 also includes: a damper structure 14. The damper structure 14 is arranged in the shell assembly 10. The damper structure 14 has a first position and a second position. When the damper structure 14 is in the first position, the damper structure 14 opens the first air outlet 12 and closes the ventilation port 13. When the damper structure 14 is in the second position, the damper structure 14 opens the ventilation port and closes the first air outlet 12.

[0102] Specifically, Figure 7The figure shows the first damper 141, the second damper 142, the damper rotating shaft 143, the spring 144, the winding wire 145, and the motor 146. The motor 146 outputs torque, and the rotation of the motor output shaft causes the winding wire 145 to contract or expand, thereby rotating the damper rotating shaft 143, and ultimately driving the first damper 141 and the second damper 142 to rotate.

[0103] According to another aspect of the present invention, a ceiling-mounted appliance is provided, comprising a housing assembly, which is the housing assembly in the above embodiment. The ceiling-mounted appliance includes an air conditioner, a bathroom heater, a ventilation fan, and the like.
