Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention relates to a refrigerator, and especially to a refrigerator used outdoors. 
         [0003]    2. Description of the Prior Art 
         [0004]    Leisure-time activities held outdoors are delighted in popularly by the masses, hence utensils for leisure-time activities used outdoors such as carriages for meat roasting stoves and refrigerators used outdoors are continuously developed, they render consumers to spend their leisure-time activities more conveniently. 
         [0005]    For instance: there have been a kind of refrigerator used outdoors developed for meat roasting with a main object of using the top surface of the refrigerator as a meat roasting table; and for making the refrigerator be moved conveniently, the refrigerator is provided on its bottom with a set of wheels. A compressor provided on the back side of the refrigerator is provided on its periphery with a rear rain proof hood to prevent encroachment of rain and snow; hence when people carry a refrigerator used outdoors for an outdoor activity, utensils need to be prepared can be reduced, particularly, when in meat roasting outdoors, they do not need to prepare another carriage for a meat roasting stove. 
         [0006]    Although the abovementioned refrigerator can allow a meat roasting stove to be placed on the top surface thereof and thereby is very convenient in use, by the fact that heat created in meat roasting may damage the refrigerator and lower the temperature keeping function of the refrigerator and thus reduce the life of use of the refrigerator, such a refrigerator thereby has quite a need for improvement. 
         [0007]    And more, in an environment for a refrigerator used outdoors, the refrigerator is subjected to exposure under a high temperature and encroachment of rain, thereby a compressor and a condenser normally are provided in a tightly closed space and result an inferior effect of heat dissipation, and a plurality of sealing strips on a door panel are subjected to exposure under a high temperature of the sunlight outdoors to speed up their ageing phenomenon, this may result incomplete sealing and thereby affect the temperature keeping function of the refrigerator. Therefore, the refrigerator used outdoors needs improvement in finding a way to increase the heat dissipation capability of a condenser in a high temperature environment to maintain the effect of operation of the refrigerator and to avoid rain from flowing into a receiving space for the refrigerator, in order to prevent the compressor and the condenser from encroachment and damage, and to slow down the ageing phenomenon of the sealing strips on the door panel and to thereby improve the temperature keeping function of the refrigerator, these are all required improvement on manufacturing the refrigerator used outdoors. 
         [0008]    In view of the above stated, the inventor of the present invention studied and provided a brand new refrigerator used outdoors to overcome the problems of damaging against and the inferior effect of heat dissipation of a refrigerator used outdoors resulted by bad environment outdoors. 
       SUMMARY OF THE INVENTION 
       [0009]    The main object of the present invention is to provide an outdoor refrigerator that can be used in a pernicious environment outdoors, and can improve the effect of heat dissipation of a condenser of the refrigerator; and more, the refrigerator can be used as a carriage for a roasting stove with which the top surface of the refrigerator can be placed thereon a roasting stove that will not damage the refrigerator, thus an object of convenient use can be attained. 
         [0010]    In order to achieve the above object, the outdoor refrigerator comprises a cabinet, a heat insulation board, a door panel, a compressor, a condenser and a rain proof plate.

         [0017]    The abovementioned rain proof plate is provided outside of the receiving chamber of the cabinet to separate the receiving chamber and the compressor as well as the condenser in the receiving chamber from the outside, the rain proof plate is provided thereon with a plurality of heat sinking holes to allow discharging of the hot air in the receiving chamber and flowing in of the cold air outside of the receiving chamber; each heat sinking hole is provided on its upper edge and two lateral sides with a rain proof cap, in order to prevent from spattering in of water drops and rains into the receiving chamber via the heat sinking hole to create problems of electric short circuiting and rusting of the compressor and the condenser. Moreover, in practicing, the rain proof plate is made of metal, in order that each heat sinking hole and its corresponding rain proof cap can be integrally punching shaped, and also can be made of stainless which is more highly corrosion resistive or made from iron plates plated with zinc and baked with varnish passing a salt fog test, thereby, the life of use outdoors of the rain proof plate can thus be prolonged. 
         [0018]    With the above stated structure, in using the outdoor refrigerator of the present invention outdoors, the roasting stove can be placed on the heat insulation board provided on the top surface of the cabinet, the heat insulation board protects the elements in of the cabinet from affecting by heat energy of the roasting stove to thereby maintain the normal operation efficiency; and more, the fan helps the condensing tubes and the heat sinking sheets to speedily dissipate heat, thus effectively increase the operation efficiency of the condenser, so that the outdoor refrigerator of the present invention still can achieve the effect of keeping food fresh even in a high temperature environment outdoors; and more, all the elements of the present invention are designed especially for using in outdoor environments, they have better material characteristics for prolonging their life of use and convenience of use. 
         [0019]    In comparison with the prior art, the outdoor refrigerator of the present invention can overcome a pernicious environment outdoors and the problems of damaging the refrigerator and of heat dissipation of a condenser; and more, the refrigerator can be used as a carriage for a roasting stove with which the top surface of the refrigerator can be placed thereon a roasting stove that will not damage the refrigerator, thus the object of convenient use can be attained.
