Description

Technical Field

[0001] The utility model relates to the field of household heating equipment, in particular to a ceiling-mounted electrical appliance. Background Art

[0002] The common structure of a bathroom heater or a space heater usually includes a box body, which includes a shell, an air collecting plate and a panel. An air duct structure is set inside the shell. The air duct structure is generally formed at the bottom of the shell, and the air collecting plate is closed to the air duct structure to form a sealed air flow channel. Under conventional design, in a product, the shell and the air duct structure are connected as one piece, such as by injection molding from the same mold. When the product function is iteratively upgraded, the shell and the air duct structure need to be re-developed and redesigned, and the cost of product iterative upgrades is high. Summary of the Invention

[0003] The purpose of the utility model is to provide a ceiling-mounted electrical appliance, which has the advantages of separating part of the air duct from the shell, facilitating iterative upgrades of product performance, effectively improving the utilization rate of the shell structure, and reducing development costs.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions:

[0005] A ceiling-mounted electrical appliance, comprising:

[0006] case;

[0007] The air duct includes a first cover and a second cover, and the first cover and / or the second cover are separately arranged from the shell.

[0008] It is further configured that the first cover body and the second cover body are both separately configured from the shell.

[0009] It is further configured that the first cover body and the second cover body are detachably connected.

[0010] Further configuration: a sealing structure is provided at the connection between the first cover body and the second cover body.

[0011] It is further configured that the air duct further comprises a volute, and the volute is at least partially arranged on the first cover body and / or the second cover body.

[0012] Further configuration: further comprising a functional module, which is arranged on the air duct;

[0013] The functional module includes at least one of an air door, a heating module, a deodorization module, a sterilization module, and an air source.

[0014] It is further configured that the second cover is located between the bottom of the shell and the first cover, and the damper and / or heating module is arranged on the first cover.

[0015] Further configuration: the ceiling appliance further includes an air blowing port and a ventilation port, the air duct has a first air outlet and a second air outlet, the first air outlet is located on the first cover, the first air outlet is suitable for connecting to the air blowing port; the second air outlet is suitable for connecting to the ventilation port;

[0016] The damper has a first position for opening the first air outlet and closing the second air outlet, and a second position for opening the second air outlet and closing the first air outlet.

[0017] It is further configured that: a mounting portion for mounting a heating module is provided on the first cover, and / or the heating module is arranged outside the air duct.

[0018] Further configuration: the ceiling appliance is a bathroom heater or a heater or an exhaust fan or a blower fan or a room cooler or an air conditioner.

[0019] In summary, the present invention has the following beneficial effects:

[0020] First, the present invention separates at least a portion of the air duct from the housing. For example, the first cover of the air duct is independent of the housing. This allows maintenance by removing only a portion of the air duct. If the heater malfunctions, simply removing the first cover allows for quick repair or replacement of functional modules within the air duct, such as the impeller, motor, and sterilization module. This significantly improves after-sales service efficiency.

[0021] Second, in this invention, the first and second covers of the air duct are separate from the housing. During product upgrades, either component can be replaced or upgraded independently, eliminating the need to redesign and remanufacture the entire product. This modular design reduces development costs, especially as the housing can be reused during product iterations. Product functionality can be upgraded simply by optimizing the air duct structure, reducing overall production costs.

[0022] Third, in this utility model, since the air duct and housing are removable, and the air duct is further divided into a removable first cover and a second cover, if one part malfunctions, it can be replaced or repaired independently, extending the product's service life. Furthermore, the split structure simplifies maintenance, reducing both the difficulty and time required for repairs. Furthermore, during the manufacturing process, separate molds can be used for the housing and air duct, respectively. This allows for more flexible adjustment and optimization of the mold structure, improving mold utilization efficiency and reducing mold development and maintenance costs.

[0023] Fourth, different products can be formed by selecting different functional modules.

[0024] Fifth, in the present invention, the heating module is located on the outside of the air duct and has sufficient installation space. Different sizes can be freely selected during the development process to effectively meet heating needs of different intensities.

[0025] Sixth, the present invention can optionally eliminate the need for a wind collector plate, reducing material usage, simplifying the structural design, and eliminating the production and assembly steps for the wind collector plate, directly lowering the product's manufacturing cost. Furthermore, the elimination of the wind collector plate eliminates additional airflow obstruction, reducing resistance in the air duct, making airflow smoother and increasing wind speed and volume.

Placing the deodorizing module 600 at the air inlet 201 of the air duct 200 effectively performs a preliminary purification of the air entering the heater, removing odor molecules from the air. This arrangement removes most odors before the air is heated or circulated internally, ensuring that the air entering the air duct 200 is fresher.

[0058] There is no specific limitation on the structure of the deodorization module 600. In this embodiment, the deodorization module 600 may be an activated carbon filter module, a photocatalytic titanium dioxide deodorization module, an ozone deodorization module, or a plasma deodorization module.

[0059] The specific structure of the wind source is not limited.

[0067] As an alternative, based on the above, the heating module 400 can be removed, while the damper 500 structure can be retained. The damper 500 can be adjusted to a position that closes the ventilation port 102 and remains in a normally closed state, thus forming a single-air blower air supply device. As an alternative, a semiconductor cooling module can be added to this structure to form a cooler product. Furthermore, a deodorizing module 600 and a sterilizing module 700 can be optionally added to this structure.

[0068] As an alternative embodiment, based on the above, the heating module 400 can be removed, while the damper 500 structure can be retained. The damper 500 can be adjusted to a position that closes the air outlet and remains in a normally closed state, thereby forming an exhaust device, such as a ventilation fan. In this way, the air duct 200 does not need to be equipped with the deodorization module 600 and the sterilization module 700.
