2. Description of the Prior Art
In our modern lives, roasting stoves are necessary utensils for people to deal with outdoor leisure or gatherings, for the purpose of increasing interest of roasting, outdoor roasting generally is to roast bigger foods, such as roasting a whole turkey, a whole suckling pig and a big cube of beef and pork etc. such as is shown in
Wherein: the electric rotating axle 91 can be serially inserted thereon with bigger foods to be roasted on the roasting stove 90, and the motor unit 92 can be used to rotate the electric rotating axle 91. When the motor unit 92 drives the electric rotating axle 91 to rotate sustainingly and slowly, fire in the roasting stove 90 can roast foods uniformly with an appropriate temperature, and the foods can be well roasted without having the situation that part of them are burnt and part not well roasted.
The roasting stove 90 has the above stated advantages, it has also a quite serious defect though, namely: the motor unit 92 has no function of water proofing, hence the roasting stove 90 only is suitable for use indoors or in sunny weather with mild wind; while in a raining or cloudy day or night with heavy dews, each time after roasting, the motor unit 92 must be detached to be stored in a room, or must be covered thereover with a water or rain proofing rain coat, to avoid the motor unit 92 to be damaged after being showered with rain or getting wetted and thereby to make short circuit or even to hurt consumers.
In view of the above stated, the inventor of the present invention provides a structure of waterproof motor for the electric rotating axle of a roasting stove based on his studying in related field and experience of years, the motor can get rid of the problems of the conventional motor unit, the problems are: the motor unit has no function of water and rain proofing, and is subjected to being damaged after being showered with rain or getting wetted; the waterproof motor of the present invention thus can achieve objects of being convenient for use and able to avoid to be subjected to being damaged after getting wetted.
The object of the present invention is to provide a structure of waterproof motor for the electric rotating axle of a roasting stove, the motor can be used in a wet environment or weather for driving to rotate the electric rotating axle of the roasting stove for roasting foods without the problem of having the motor damaged.
In order to achieve the above object, the structure of waterproof motor for the electric rotating axle of a roasting stove of the present invention can be installed on the roasting stove to allow rotation of the electric rotating axle for operating the roasting stove, the structure of waterproof motor includes a housing composed of an upper cover and a lower lid, inside the housing there is a receiving space in which a fixing seat is provided on the lower lid; the fixing seat is provided thereon with a waterproof sleeve and a driving member which has a dynamic axle, the dynamic axle is extended through the waterproof sleeve to link with the electric rotating axle to rotate it.
Wherein: the housing is provided thereon with a hole for extending of an electric power line therein to connect the hole of the driving member, a sealing sleeve for sealing the hole is provided between the electric power line and the hole; and more, the housing is provided thereon with a control switch for controlling the driving member and a switch receiving cavity for receiving the control switch; wherein the control switch is a waterproof switch, and the control switch is sealed in the switch receiving cavity.
The above mentioned lower lid has an axle hole for extending of the waterproof sleeve out of it, so that the dynamic axle can be extended through the waterproof sleeve to connect the electric rotating axle of the roasting stove; moreover, a waterproof sealing piece is tightly pressed between the fixing seat and the lower lid, when the upper cover and the lower lid get close to connected with each other, the upper cover can tightly press against the lower lid to achieve the object of preventing invading of evaporated water against the driving member.
Operation in practice of the above elements is described in details as below:
Wherein: for the purpose of reducing the working hours in assembling and increasing the tightness of connecting of components after assembling, and for the purpose of achieving the object of water proofing, in practicing, the above mentioned upper cover can be provided on its top surface with a recess having on its bottom first screw holes; and in practicing, the fixing seat can include a bottom plate, two lateral sides of the bottom plate are provided each with an upright fixing portion parallel to each other, the two fixing portions have therebetween an appropriate gap for providing of the above mentioned sleeve on the bottom plate; each fixing portion is in a shape of inversed “L”, and is provided at a position in corresponding to that of a corresponding first screw hole with a second screw hole; the first and second screw holes are provided for locking therein bolts to make fixedly connecting of the upper cover with the fixing seat.
And more, when in practicing, the bottom plate of the fixing seat can be connected by welding onto the lower lid, while the sealing piece is cut to have a notch centrally, in order that the bottom plate can be connected by welding onto the lower lid. And for the purpose of obtaining a better waterproofing effect, the bottom plate can be used to cover the notch and the areas of the sealing piece around the notch.
Additionally, when in practicing, the above mentioned recess on the top surface of the upper cover can be provided thereon with a waterproofing sticker for sealing the first screw holes, in order to increase the waterproofing effect, and the waterproofing sticker can be provided on its surface with marks for advertising, recognition etc.
Moreover, when in practicing, the above mentioned driving member includes electromagnetic elements such as a set of stator and a set of rotor etc., in order to reach an object of rotating, the driving member can further include two fixing lugs having thereon a fixing hole each, and the fixing portions of the fixing seat are provided at positions in corresponding to those of the fixing holes with mounting holes, screws can be extended into the fixing holes and the mounting holes for locking and connecting of the driving member to/with the fixing seat.
Additionally, for the purpose of conveniently mounting the motor on the roasting stove, the lower lid can be provided thereon with a hanging hole for hanging it on the roasting stove; in practicing, so long that the roasting stove is provided on its wall with a support having a hanging hook for hanging the hanging hole on it, and the above mentioned dynamic axle is connected with the electric rotating axle of the roasting stove, assembling of the motor thus is completed.
As compared with the conventional technique, the structure of waterproof motor for the electric rotating axle of a roasting stove of the present invention can avoid invading of evaporated water against the electric components of it, hence it works in a wet environment or weather to rotate the electric rotating axle of the roasting stove for roasting foods without the problem of having the motor damaged.
