Description

Technical Field

[0001] This utility model relates to the field of electrical technology, and more specifically, to a housing assembly and a ceiling appliance having the same. Background Technology

[0002] A bathroom heater is a common indoor heating device, its main function being to raise the temperature of the bathroom by heating the air. The size of the heater's casing directly affects the size of the volute, which in turn affects the airflow. In traditional bathroom heater designs, the casing size is limited by the size of the ceiling panels and the width of the joists, resulting in the current technology having reached its maximum casing size. Further increasing the casing size to increase airflow would inevitably lead to an excessively large casing that cannot be installed through the mounting openings in the ceiling panels (standard structural components) or through the joists formed on the ceiling panels or large panels. Due to these existing technological limitations, the airflow of bathroom heaters remains relatively low, failing to meet the requirements of environments demanding higher airflow, thus limiting the practicality of current bathroom heater technology.

[0003] There is currently no good solution due to the problems with existing technologies. Utility Model Content

[0004] The main objective of this invention is to provide a housing assembly and a ceiling appliance having the same, in order to solve the problem of insufficient airflow inside the housing due to the limited size of the volute in the prior art.

[0005] To achieve the above objectives, according to one aspect of the present invention, a housing assembly is provided. The housing assembly includes: a housing having at least two volute side plates, each volute side plate having an impeller disposed therein, and at least one of the two volute side plates having an opening; and a splicing volute, the splicing volute being movably connected to the volute side plates such that the splicing volute has a blocking position that moves away from the impeller to block at least part of the opening, and a clearance position that moves towards the impeller to be housed within the housing.

[0006] Furthermore, when the spliced ​​volute is in the blocking position, at least part of the spliced ​​volute protrudes outward from the outside of the opening, so that the spliced ​​volute and the volute side plate surround the volute enclosure.

[0007] Furthermore, when the spliced ​​volute is in the avoidance position, at least part of the impeller is located inside the spliced ​​volute.

[0008] Furthermore, each volute side plate includes a first side plate and a second side plate, which are spaced apart to form an opening. When the spliced ​​volute is in the blocking position, one end of the spliced ​​volute abuts against the first side plate, and the other end of the spliced ​​volute abuts against the second side plate.

[0009] Furthermore, at least one limiting platform is provided near the opening of the volute side plate, and the limiting platform is located on the side of the volute side plate away from the impeller.

[0010] Furthermore, a limiting groove is formed between the inner wall of the limiting platform and the first side plate or the second side plate. When the splicing volute is in the blocking position, at least part of the splicing volute is located in the limiting groove.

[0011] Furthermore, the casing has at least two volute air ducts and at least one connecting air duct, with each volute side plate corresponding to one volute air duct, and both volute air ducts are connected to the connecting air duct.

[0012] Furthermore, the housing is provided with an air outlet and an air exchange port, and the ventilation duct is connected to the air outlet and the air exchange port. The housing assembly also includes a damper structure, which is disposed in the ventilation duct. The damper structure has a first position and a second position. When the damper structure is in the first position, the damper structure opens the air outlet and closes the air exchange port. When the damper structure is in the second position, the damper structure opens the air exchange port and closes the air outlet.

[0013] Furthermore, the spliced ​​volute includes: an outer plate, which is an arc-shaped plate structure; and at least two side plates, which are disposed at both ends of the outer plate along the width direction of the outer plate and are disposed opposite to each other.

[0014] According to another aspect of the present invention, a ceiling electrical appliance is provided, which has a housing assembly, the housing assembly being the housing assembly described in the above embodiment.

[0015] By applying the technical solution of this utility model, at least two volute side plates are provided, and each volute side plate contains an impeller, which increases the air volume of the whole machine. The spliced ​​volute is provided with a blocking position for blocking the opening and a avoidance position for avoiding the opening. The spliced ​​volute in the blocking position expands the capacity of the air duct structure, thereby increasing the air volume. The spliced ​​volute in the avoidance position saves the overall longitudinal space of the shell assembly and improves the flexibility of the shell assembly during installation.

[0035] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] It should be noted that in the existing technology, some ceiling electrical 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 main unit of the ceiling electrical appliance must be installed first, followed by the ceiling panels (such as gypsum board and large panels). Furthermore, this installation sequence determines that the ceiling electrical appliance can only be suspended from the ceiling, which has the disadvantage of inconvenience in installation, disassembly and maintenance.

[0040] For example, the elongated and narrow design of linear bathroom heaters is aesthetically pleasing and popular with users. However, because the ceiling panel only has through holes that match the size of the mask (the holes are too narrow for the main unit to fit through into the space between the ceiling panel and the ceiling), it's impossible to install the ceiling panel before installing the linear bathroom heater. The heater must be suspended from the ceiling before the panel is installed. This solution presents inconveniences in installation, disassembly, and maintenance, and in some situations, it may even be impossible to install at all.

[0041] Combination Figures 1 to 7 As shown, according to a specific embodiment of the present invention, a housing assembly is provided.

[0042] Specifically, such as Figure 1 As shown, the housing assembly includes: a housing 10 having at least two volute side plates 11, each volute side plate 11 having an impeller 20 disposed therein, and at least one of the two volute side plates 11 having an opening 12; and a splicing volute 30, the splicing volute 30 being movably connected to the volute side plates 11 such that the splicing volute 30 has a blocking position that moves away from the impeller 20 to block at least part of the opening 12, and a clearance position that moves toward the impeller 20 to be housed within the housing 10.

[0043] In this embodiment, by setting at least two volute side plates 11, each volute side plate 11 contains an impeller 20, forming a fan structure. Compared with the traditional single impeller structure, the coordinated operation of multiple fans improves the blowing efficiency and increases the air volume of the housing assembly. The volute side plates 11 and the impeller 20 form an internal air duct structure for the fan. The splicing volute 30 is set with a blocking position for the blocking opening 12 and a clearance position for the clearance opening 12. The splicing volute 30 in the blocking position expands the capacity of the fan air duct structure, thereby increasing the fan air volume. The splicing volute 30 in the clearance position saves the overall longitudinal space of the housing assembly and improves the flexibility of the housing assembly during installation.

[0044] It should be noted that the shell assembly can be divided into multiple shell units, which can be assembled into shell 10, or the shell units can be installed separately. For example, when there are two shell units, the installation steps of the shell assembly include: 1. Controlling the splicing volute 30 to be in the clearance position; 2. Installing the first shell unit into the mezzanine space through the hole in the ceiling panel; 3. Laying down the shell unit installed in the mezzanine space clockwise; 4. Controlling the splicing volute 30 to be in the blocking position; 5. Installing the second shell unit into the mezzanine space through the hole in the ceiling panel; 6. Laying down the second shell unit installed in the mezzanine space clockwise, assembling the two shell units. At this time, the shell assembly is placed flat in the mezzanine space.

[0045] Furthermore, when the spliced ​​volute 30 is in the blocking position, at least a portion of the spliced ​​volute 30 protrudes outward from the opening 12, so that the spliced ​​volute 30 and the volute side plate 11 form a volute enclosure.

[0046] The volute 30 can be connected to the housing 10 or to the volute side plate 11, as long as the volute 30 and the volute side plate 11 can be arranged together to form a volute enclosure. The volute enclosure forms at least part of the fan housing, and the volute duct 13 is at least partially located inside the fan. In this embodiment, the volute duct 13 is located inside the fan.

[0047] Combination Figure 1 , Figure 5 As shown, the spliced ​​volute 30 with the protruding opening 12 increases the capacity of the air duct structure, thereby increasing the air volume.

[0048] Specifically, the housing 10 has at least two volute air ducts 13 and a connecting air duct 14. Each volute side plate 11 is provided with a corresponding volute air duct 13, and both volute air ducts 13 are connected to the connecting air duct 14.

[0049] The aforementioned volute air duct 13 is the air duct between the volute side plate 11, the spliced ​​volute 30, and the impeller 20. In this embodiment, there are two volute air ducts 13. The aforementioned connecting air duct 14 is the air duct connecting the two volute air ducts 13. The damper structure 40 is disposed within the connecting air duct 14. The housing 10 is provided with an air outlet 15 and an air exchange port 16, and the connecting air duct 14 is connected to the air outlet 15 and the air exchange port 16. Therefore, the spliced ​​volute 30 expands the capacity of the volute air duct 13 to increase the airflow, and the connecting air duct 14 also increases the overall air duct capacity of the housing assembly, further increasing the airflow.

[0050] Furthermore, the damper structure 40 is disposed within the ventilation duct 14. The damper structure 40 has a first position and a second position. When the damper structure 40 is in the first position, the damper structure 40 opens the air outlet 15 and closes the ventilation port 16. When the damper structure 40 is in the second position, the damper structure 40 opens the ventilation port 16 and closes the air outlet 15.

[0051] Combination Figure 5 , Figure 7As shown, the volute air duct 13 is connected to the connecting air duct 14, and the air outlet 15 and the ventilation port 16 are also connected to the connecting air duct 14. This allows the air flowing out of the volute air duct 13 to be discharged through the air outlet 15 or the ventilation port 16. Based on this, a damper structure 40 is installed within the connecting air duct 14. By switching the position of the damper structure 40, the volute air duct 13 can be connected to the air outlet 15 and the ventilation port 16 respectively. When the damper structure 40 is in position... In the first position, the damper structure 40 opens the air outlet 15 and closes the ventilation port 16. This means the volute duct 13 is connected to the air outlet 15 but not to the ventilation port 16, and the housing assembly operates in either blowing or heating mode. In the second position, the damper structure 40 opens the ventilation port 16 and closes the air outlet 15. This means the volute duct 13 is connected to the ventilation port 16 but not to the ventilation port 16, and the housing assembly operates in either ventilation mode. Switching between ventilation and blowing modes using the damper method saves space by reducing the size of the fan and its accessories, increasing the duct structure's capacity, improving the overall airflow (air output, heating, or ventilation), enhancing housing assembly performance, and reducing costs.

[0052] Furthermore, when the splicing volute 30 is in the avoidance position, at least part of the impeller 20 is located inside the splicing volute 30.

[0053] Combination Figure 3 , Figure 4 , Figure 7 As shown, when the housing assembly is in a non-working state, the splicing volute 30 is moved toward the side of the impeller 20, so that the splicing volute 30 is suspended on at least part of the impeller 20 for fixation, preventing the splicing volute 30 from shifting position and ensuring the stability of the splicing volute 30.

[0054] Furthermore, each volute side plate 11 includes a first side plate 111 and a second side plate 112. The first side plate 111 and the second side plate 112 are arranged at a distance to form an opening 12. When the spliced ​​volute 30 is in the blocking position, one end of the spliced ​​volute 30 abuts against the first side plate 111, and the other end of the spliced ​​volute 30 abuts against the second side plate 112.

[0055] Combination Figure 1 , Figure 5 As shown, the first side plate 111 has an arc-shaped plate structure. The first end of the first side plate 111 is connected to one side wall of the middle part of the housing 10. The first end of the second side plate 112 is connected to the other side wall of the middle part of the housing 10. An opening 12 is formed between the second end of the first side plate 111 and the second end of the second side plate 112. One end of the splicing volute 30 abuts against the second end of the first side plate 111, and the other end of the splicing volute 30 abuts against the second end of the second side plate 112, thereby achieving positional limitation. This structure is simple and saves costs.

[0056] Furthermore, at least one limiting platform 113 is provided on the side of the volute side plate 11 near the opening 12, and the limiting platform 113 is located on the side of the volute side plate 11 away from the impeller 20.

[0057] In one embodiment, a limiting platform 113 is provided on the side plate 11 of the volute near the opening 12, that is, a limiting platform 113 is provided on the first side plate 111 near the opening 12 or on the second side plate 112 near the opening 12, so as to limit one end of the spliced ​​volute 30.

[0058] In another embodiment, the volute side plate 11 is provided with two limiting platforms 113 near the opening 12, that is, the first side plate 111 and the second side plate 112 are respectively provided with a limiting platform 113 near the opening 12, so as to limit the two ends of the spliced ​​volute 30.

[0059] like Figure 1 , Figure 2 , Figure 5 , Figure 6 As shown, the limiting platform 113 is located on the outer ring of the first side plate 111 or the second side plate 112. One end of the limiting platform 113 is smoothly connected to the first side plate 111 or the second side plate 112. The second end of the limiting platform 113 protrudes along the radial direction of the first side plate 111 or the second side plate 112 and extends toward the side of the opening 12. The splicing volute 30 is an arc-shaped plate structure. This arrangement makes the structure of the limiting platform 113 match the structure of the splicing volute 30.

[0060] Specifically, a limiting groove 114 is formed between the inner circumferential surface of the limiting platform 113 and the first side plate 111 or the second side plate 112. When the splicing volute 30 is in the blocking position, at least a portion of the splicing volute 30 is located within the limiting groove 114. This arrangement allows the limiting platform 113 to stop the splicing volute 30, preventing it from detaching from the volute side plate 11 when it moves away from the impeller 20, thus ensuring the stability of the splicing volute 30.

[0061] Furthermore, the spliced ​​volute 30 includes: an outer plate 31, which is an arc-shaped plate structure; and side plates 32, which are at least two in number. The at least two side plates 32 are disposed at both ends of the outer plate 31 along the width direction of the outer plate 31, and the at least two side plates 32 are disposed opposite to each other.

[0062] According to another aspect of this utility model, a ceiling-mounted electrical appliance is provided, which has a housing assembly, the housing assembly being the same as that described in the above embodiment. The ceiling-mounted electrical appliance includes, but is not limited to, air outlet devices such as kitchen air conditioners, non-kitchen air conditioners, bathroom heaters, and fresh air systems. The housing assembly includes: a housing 10, the housing 10 having at least two volute side plates 11, each volute side plate 11 having an impeller 20 disposed therein, and at least one of the two volute side plates 11 having an opening 12; and a splicing volute 30, the splicing volute 30 being movably connected to the volute side plates 11, such that the splicing volute 30 has a blocking position that moves away from the impeller 20 to at least partially block the opening 12, and a clearance position that moves towards the impeller 20 to be housed within the housing 10.

[0063] By setting at least two volute side plates 11, each volute side plate 11 contains an impeller 20. Compared with the traditional single impeller structure, the coordinated operation of multiple impellers 20 improves the blowing efficiency and increases the air volume of the housing assembly. An air duct structure is formed between the volute side plates 11 and the impellers 20. The splicing volute 30 is set with a blocking position for the blocking opening 12 and a clearance position for the clearance opening 12. The splicing volute 30 in the blocking position expands the capacity of the air duct structure, thereby increasing the air volume. The splicing volute 30 in the clearance position saves the overall volume of the housing assembly and improves the flexibility of the housing assembly during installation.

[0064] When the housing assembly in the above embodiments is applied to ceiling appliances, since the splicing volute 30 can protrude outward to increase the flow area of ​​the air duct structure, the housing 10 can have a larger air volume, and at least two splicing volutes 30 are provided, thereby making the air outlet effect of the ceiling appliances better, more suitable for environments with high air volume requirements, and improving the air outlet performance and practicality of the ceiling appliances.

[0065] When the housing assembly is applied to a linear bathroom heater, the splicing volute 30 protrudes outward onto the housing 10, increasing the airflow area of ​​the linear bathroom heater. This allows for a larger air volume without modifying the dimensions of the bathroom heater fan and housing assembly, resulting in better airflow performance. Furthermore, the linear bathroom heater positions the air outlet 15 and the ventilation port 16 opposite each other, using the damper structure 40 to switch between blocking and avoiding the air outlet 15 and the ventilation port 16. This allows for switching between blowing and ventilation functions using dual fans, saving on one fan and its accessories. This achieves performance optimization and simplified installation in the bathroom heater technology field, improving the airflow performance and practicality of the bathroom heater. At the same time, the ultra-narrow shape of the linear bathroom heater is more aesthetically pleasing and caters to user aesthetic standards.
