Description
Technical field
The present invention relates to a kind of electric household appliance, especially relate to a kind of integrated roof built-in electric household appliance, belong to a kind of electric household appliance that is used for integrated furred ceiling.
Background technology
Now integrated electrical panel is a ceiling is usually split, the host via a bracket or connecting member fixed to the retainer such as triangular keel, the keel panel in the card to the triangle, and the host of the mounting surface is located on the upper surface of the triangular keel, such triangle the distance between the keel and the ceiling must be greater than the height of the electrical, or electrical appliances will not appear in place of the phenomenon, so that, on the ceiling panel and the ceiling so that the interlayer between the higher height, thus reducing the effective space of the room , leading to the room in the space can not be effectively utilized, therefore, is that a waste of resources; addition, shorten the distance between the floor and the ceiling, giving a certain amount of pressure, greatly reducing the quality of the living environment of people, is not conducive to people's health.If an open date is March 30, 2005, Publication No. CN1601189 of Chinese patent discloses a ceiling built-in appliances split installation method and apparatus, the ceiling split device built-in appliances, including a keel and a composition roof ceiling panels, in two adjacent fixed keel placed between the top of the main body with appliances, in the bottom of the main body has at least one through the clip and rail engagement in the keel below the ceiling panel as a mask plate heater , will host appliances decomposed into the upper body and the lower part of the mask plate in two parts, the mask-shaped plate made indoor ceiling panel, ceiling panel, together with other articles with the use of the card slot or groove between the panels and embedded with uniform fixed keel below the ceiling to form a complete roof surface, while the main body is fixed plate mounted on the side of the roof inside the mask; although the device is able to maintain the overall consistency of the indoor ceiling, so that the overall appearance of the home environment, can reduce the installation cost of using But the structural design of the device is not reasonable, appliance main body mounted directly on the keel, not only the inconvenience of installation, the space in the room can not be effectively utilized, but also makes it difficult panel and the appliance main body better match.
Because the panel and the main frame of existing integrated ceiling appliance are splits; Make that the structure design of electrical equipment main is reasonable inadequately, integrality is relatively poor, and sealing is relatively poor; The situation that occurs light leak and gas leakage has easily hindered the promotion and application of integrated furred ceiling to a certain extent.Electrical equipment main is mounted on the upper surface of triangle keel, and this has just increased the whole height of casing.In addition; The installation and removal inconvenience of existing integrated ceiling appliance; Need to install earlier electrical equipment main; And then panel sticked into the correspondence position of electrical equipment main, and operate loaded down with trivial detailsly, be to be connected between main frame and the triangle keel through mechanical systems such as support or jump rings; When ventilation fan or air heating machine carry out work; Main frame can produce vibration, thereby the phenomenon that produces noise is more serious, influences the use of equipment.
In sum, also there is not a kind of reasonable in design at present, easy for installation, the integrated roof built-in electric household appliance of good airproof performance.
Summary of the invention
The objective of the invention is to overcome the above-mentioned deficiency that exists in the prior art, and a kind of reasonable in design is provided, dependable performance is convenient to installation and removal, can effectively utilize the integrated roof built-in electric household appliance in space.
The present invention addresses the above problem the technical scheme that is adopted: this integrated roof built-in electric household appliance comprises panel, main frame and keel; Its characteristics are: also be provided with connector and at least two bearing parts; Said panel directly is fixed on the main frame through connector; This panel and main frame are complementary; Said main frame is through bearing part and keel fixed installation, and the bottom surface of this main frame is positioned at the below of keel supporting surface.Make of the present invention easy for installationly thus, the bottom surface of main frame is positioned at the below of keel supporting surface, helps shortening the spacing between keel and the ceiling, thereby plays the function of effectively utilizing the space in the room, has improved the utilization rate of resource.Panel and main frame link together and form a complete electrical equipment, guarantee that effectively electrical equipment has good sealing property, situation such as light leak, gas leakage can not occur, have promoted the overall performance of electrical equipment.Panel directly is fixed on the main frame through connector, makes overall structure simple more, firmly, also is convenient to the installation and removal of panel, can effectively reduce the noise that produces between the main frame and panel in the main frame running, plays the noise reduction effect.
The middle and lower part of bearing part according to the invention is shaped as Ω shape structure, and the upper surface of said Ω shape structure the right and left is respectively left plane and right plane, forms a keel draw-in groove in the middle of this Ω shape structure; Described keel are connected in this keel draw-in groove, and described main frame is fixed on the left plane or right plane of said bearing part Ω shape structure.
Bearing part according to the invention comprises left insert-connecting plate, right insert-connecting plate and fixed screw; The bottom of said left insert-connecting plate is provided with left fixing feet; This left side fixing feet is provided with left fixing hole; The top of said left insert-connecting plate is provided with recessed; This recessed is provided with slideway, is provided with left screw hole in the said slideway; The bottom of said right insert-connecting plate is provided with right fixing feet; This right side fixing feet is provided with right fixing hole, and the top of said right insert-connecting plate is provided with projection, and this projection is provided with guide rail; Be provided with right screw hole in the said guide rail, the shape of this guide rail all is complementary with slideway with size; Guide rail on the said right insert-connecting plate is connected in the slideway on the left insert-connecting plate; Said fixed screw cross-under is in left screw hole and right screw hole; Said left insert-connecting plate and right insert-connecting plate fix through fixed screw, form a keel draw-in groove between this left side insert-connecting plate and the right insert-connecting plate; Said main frame is fixed in the right fixing hole of left fixing hole and/or right insert-connecting plate of left insert-connecting plate.Make that thus the structure design of the bearing part among the present invention is more reasonable, performance is more reliable, makes that the installation and removal of main frame are convenient, helps the dismounting between main frame and the keel, is convenient to the maintenance and the maintenance of equipment, has improved operating efficiency.
