BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION
[0011] The following is a detailed description of an embodiment of the utility model in conjunction with the accompanying drawings. This embodiment is implemented on the premise of the technical solution of the utility model, and a detailed implementation method and a specific working process are given, but the protection scope of the utility model is not limited to the following embodiment.
[0012] like Figure 1 As shown, the front hollow cooked food cabinet with back-mounted evaporator direct cooling of the utility model comprises a base 1 and a cabinet body 2 located above the base 1, a refrigeration unit 3 and a control system are arranged in the base 1, and a double-layer hollow glass cabinet door 4 with good heat preservation effect is arranged on the front side of the cabinet body 2. Usually, the double-layer hollow glass cabinet door 4 is a flat door hingedly connected to the top of the cabinet body 2 or a sliding door with a planar structure.
[0013] The rear side of the cabinet 2 is provided with an evaporator 5 connected to the refrigeration unit 3 through a pipeline. The evaporator 5 is a flat structure as a whole, adopts a copper tube aluminum fin structure, and is provided with a multi-row perforated top cover plate on the top. The evaporation coil 6 of the evaporator 5 is arranged at the bottom of the cabinet 2, and extends forward from the drainage groove 7 on the rear side of the cabinet 2 to the front side of the cabinet 2, which can not only reduce the temperature of the front side of the cabinet 2, but also prevent the drainage groove 7 from being blocked by ice by hot air defrosting. In order to further improve the insulation effect, a foam insulation layer is also provided in the cabinet 2, which is located at the back of the evaporator 5 and surrounds the outside of the evaporation coil 6.
[0014] A porous storage plate 8 is arranged above the evaporating coil 6. The porous storage plate 8 is a horizontal plate spaced apart from the evaporating coil 6, and a plurality of cold air holes 9 are evenly spaced apart thereon. The evaporating coil 6 continuously absorbs the heat from the surrounding air to lower its temperature. The cold air accumulates under the porous storage plate 8 and is dispersed to the storage space above through the densely stacked cold air holes 9, exchanging heat with the upper air, and finally forming a constant temperature environment. The above-mentioned heat conduction heat transfer method can effectively reduce the airflow in the cabinet, prevent the food from drying out, and improve the quality and taste of the food; at the same time, due to the large density of the cold air holes 9, the heat conduction speed of the cold air is faster, which can achieve the purpose of rapid cooling.
[0015] A temperature sensor 10 is provided in the storage space above the porous storage plate 8, and the signal output end of the temperature sensor 10 is electrically connected to the signal input end of the control system, and the control output end of the control system is electrically connected to the control input end of the refrigeration unit 3. Usually, the temperature sensor 10 is arranged on the side of the middle of the evaporator 5 facing the double-layer hollow glass cabinet door 4. When the temperature of the storage space exceeds the set value, the temperature sensor 10 sends a signal to the control system to start the refrigeration unit 3 until the temperature reaches the standard.
[0016] It should be noted that, in the description of the present invention, terms indicating orientation or positional relationships, such as "front", "rear", "left", "right", "vertical", "horizontal", "inside", "outside", etc., are based on the orientation or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
