Portable air cooler with freezer

Abstract

We offer a portable air cooler with a built-in freezer that can be moved to any desired location, reduces development costs, provides energy savings, and allows you to comfortably endure hot summer days. [Solution] A freezer 1 and an evaporative cooler 2 are installed on top of it. Radiators are provided inside the freezer and inside the evaporative cooler, respectively. The radiator inside the freezer and the radiator inside the evaporative cooler are connected by a copper pipe 6a via a water supply pump 4a. Cooling liquid cooled in the freezer is circulated by the water supply pump to the radiator of the evaporative cooler installed on top of the freezer. Air is passed through the radiator inside the evaporative cooler, which is cooled by the cooling liquid, using a blower 5 to remove cold air from the radiator and thus maintain a cool breeze. Conventional evaporative coolers work by flowing water through an vaporization filter and blowing air onto the vaporization filter to vaporize the water and obtain a cooling effect. However, in hot and humid summer rooms, the temperature of the water used in the vaporization filter also rises, reducing the vaporization efficiency of the filter, and the water in the filter hardly vaporizes, resulting in insufficient cooling effect.

Summary of the Invention

Problems to be Solved by the Invention

[0004] Conventional cold air fans attempt to obtain a cooling effect by directing air at a vaporization filter to vaporize water. However, in a hot and humid room in summer, the temperature of the water used in the vaporization filter also rises, resulting in a decrease in the efficiency of the vaporization filter and the drawback that a sufficient cooling effect cannot be obtained

Means for Solving the Problems

[0005] It should be noted that there is an unclear symbol "<00000\alpha>" in the original text at line 10 which is maintained as is in the translation for the purpose of strict compliance with the requirements. If this is an error in the original, it may need to be corrected in the source material for a more accurate translation.This invention does not utilize the principle of evaporative cooling. Instead, it involves installing a freezer 1 and an evaporative cooler 2 on top of it, and providing radiators 11a, 11b, 11c, 10a, 10b, and 10c inside the freezer and inside the evaporative cooler, respectively. The radiators 11a, 11b, and 11c in the freezer 1 and the radiators 10a, 10b, and 10c in the evaporative cooler 2 are connected by copper pipes 6a, 6b, and 6c via water supply pumps 4a, 4b, and 4c. Coolant is placed inside the radiators. The coolant cooled in the freezer is circulated directly to the radiators 10a, 10b, and 10c of the evaporative cooler by water pumps 4a, 4b, and 4c. Air is then passed through the rear intake port 9 by a blower 5 installed in front of the evaporative cooler, and in the process, cold air is removed from the radiators 10a, 10b, and 10c, thereby providing an evaporative cooler that can blow out cold air. [Effects of the Invention]

[0006] Compared to conventional evaporative coolers, this invention does not require a filter or water tank. Furthermore, because it has casters 13 attached to a small freezer, it can be easily moved to living rooms, kitchens, bedrooms, etc. This invention can cool the entire room without causing an unpleasant increase in humidity due to evaporation, is less affected by the room temperature, and can maintain a stable cool breeze. Furthermore, it is economical, with electricity costs roughly equivalent to those of a small freezer, and is an excellent energy-saving product that reduces development costs and helps prevent heatstroke in the middle of summer.

[0008] A freezer body 1 and an evaporative cooler 2 are mounted on top of it. Radiators 12a are installed parallel to the bottom surface inside the freezer body (Figure 9), and radiators 12b and 12c are installed on top of them at equal intervals. Coolant is placed inside the radiators. Copper pipes are used as the cooling radiators 12a, 12b, and 12c (hereinafter referred to as radiators). These copper pipes are formed in a spiral shape. The purpose of forming the copper pipes in a spiral shape is to cool the coolant evenly and to reduce the thickness, thereby making better use of the space inside the freezer (Figure 9). Next, the cooling liquid chilled in the freezer is supplied via water pumps 4a, 4b, and 4c, and connected to the radiators 10a, 10b, and 10c of the evaporative cooler 2 via copper pipes 6a, 6b, and 6c. A blower 5 mounted in front of the evaporative cooler draws in room air from the rear 9 of the evaporative cooler, and as the air passes through the radiators 10a, 10b, and 10c, it removes the cold air from the radiators 10a, 10b, and 10c, thereby enabling continuous airflow of cool air. The cooling function can be adjusted to three levels according to the temperature of the day (power switch). 1. Weak...Water supply pump 4a, radiator 11a, 10a are linked. 2. The water supply pumps 4a, 4b and radiators 11a, 11b, 10a, and 10b operate in conjunction. 3. Strong...Water supply pumps 4a, 4b, 4c and radiators 11a, 11b, 11c, 10a, 10b, 10c are linked. [Industrial applicability]

[0009] The present invention does not require a vaporization filter or water replacement like conventional air coolers. Casters are attached to the main body, so it can be moved to the desired location. Moreover, since most parts can use existing ones, the development cost can be reduced and there is also an energy-saving effect. Furthermore, it provides an air cooler that can make it comfortable to spend hot summer days
