Abstract: PURPOSE:To effect normal cooling effect and restrain the amount of leakage of the heat of a dewing preventing pipe into the case of a refrigerator, by a method wherein several pipes of a built-in auxiliary condenser are arranged on the side surface of an outer casing and heat conduction sealer is poured around the pipes, then, the pipes are fixed by aluminum foils. CONSTITUTION:Most of auxiliary condenser pipe 20 is adhered to and arranged on the rear surface of the side surface 2b of the outer casing 2 of a refrigerator main body 1 through heat conduction sealer 21 and a heat conductive member such as aluminum foils 22 or the like while a part of the pipe 20 is arranged on the peripheral rim of the opening of the main body 1 as a dewing preventing pipe 20a. High-temperature refrigerant gas from a compressor 12 is introduced into a main condenser pipe 5 and the auxiliary condenser pipe 20 and the heat thereof is dissipated to the outside of the refrigerator through both side surfaces 2b of the outer casing 2 of the main body 1. The number of rows of the auxiliary condenser pipe 20 is small and heat dissipating effect is obtained by the heat conduction sealer 21 and the heat conductive members such as the aluminum foils 22 and the like, therefore, the leakage of heat toward an inner casing 3 through a heat insulating member 4 is very small whereby cooling effect and heat dissipating effect are effected normally. On the other hand, a dewing preventing pipe 20a is arranged on the peripheral rim of the opening of the refrigerator main body 1 and heats the peripheral rim to prevent it from dewing, however, it is arranged on the inside flange 23 of the outer casing 2, therefore, useless leakage of heat into the refrigerator may be reduced.

Abstract: PROBLEM TO BE SOLVED: To uniformly and effectively cool a refrigeration chamber and a vegetable chamber by expanding an internal volume of the refrigeration chamber and the vegetable chamber. SOLUTION: The present refrigerator 40 includes a refrigeration chamber 41, a vegetable chamber 43, and a freezing chamber 44 disposed in this order from an upper portion. Herein, a damper apparatus 62 is provided such that an air fan 57 is disposed rearwardly of a low temperature chamber 42 included at a lower portion in the refrigeration chamber 41. An air amount control board 58 is inserted and fixed into a recess portion thereof, and a temperature adjusting section is disposed on a protrusion thereof. As a result, the interior sizes of the vegetable chamber 43 and the refrigeration chamber can be expanded. Further, a cold air fan passage 59 provided on the back surface of the refrigeration chamber 41 and a substantially L-shaped fan air passage 71 are communicated with each other, whereby the inside of the refrigerator is uniformly cooled with a cold air stream from the upper portion and the back surface to reduce uneven temperature distribution.

Abstract: PROBLEM TO BE SOLVED: To improve cooling efficiency for a refrigeration chamber and a vegetable chamber and ensure an improvement of fool insulation property and energy saving and further silencing in a refrigerator including from an upper portion the refrigeration chamber, the vegetable chamber, and a freezing chamber. SOLUTION: The present refrigerator includes from an upper portion a refrigeration chamber 44, and a freezing chamber 46 at a lower portion, and further a vegetable chamber 45 between the refrigeration chamber 44 and the freezing chamber 46. Herein, a condenser 60 is disposed rearwardly of the vegetable chamber 45 through a heat insulation wall 59, and an air fan 62 is disposed rearwardly of the refrigeration chamber 44. As a result, fan air resistance to the refrigeration chamber 44 and the vegetable chamber 45 is reduced, and cooling capability is improved by indirectly cooling properly the refrigeration chamber with a condenser 60.

Abstract: PROBLEM TO BE SOLVED: To appropriately maintain a refrigeration temperature band and a low- temperature band and to freshly maintain accommodated food for a long time by providing a control means for operating a compressor and a blower based on the temperature detection means of a freezing room and a control means for switching a damper device based on the temperature detection means of a switching room. SOLUTION: The room temperature of a switching room 29 that can be switched to a freezing temperature band and the other temperature bands is detected by a switching room temperature detection means 42, and the room temperature is compared with a setting temperature by a room temperature judgment means 46. When the room temperature is higher by T1, a damper device 40 is opened by a damper device control means 47. On the other hand, when the room temperature is lower, the damper device 40 is closed. Furthermore, a heater device 44 is turned on and the temperature of the switching room 29 is preserved by the command of a heater device control means 48 while a damper device 37 is closed. In this manner, cold air is sent from a switching room ceiling duct 39 to the witching room 29 and the cold air is returned from the switching room 29 to a cooler 37 via a suction duct 41, thus maintaining the temperature of the switching room 29 at a setting temperature.

Abstract: PURPOSE:To reduce the invading amount of the heat of a dewing preventing pipe into the case of a refrigerator and obtain efficient cooling effect, by a method wherein the inlet port and the outlet port of the dewing preventing pipe are arranged respectively so as to be positioned at the upper and lower positions of a transversal partition or the left-and-right positions of a lateral partition while the other part of the same pipe is formed by bending. CONSTITUTION:A dewing preventing pipe 11 enters from a transversal partition 5a and enters through a lateral partition 6b, then, is U-turned to penetrate through the transversal partition 5b and is run along the upper surface 20 of the main body 1 of a refrigerator. The heat of high-pressure refrigerant gas from a compressor 15 is dissipated in a condenser 16 and the gas is liquefied, then, flows into the dewing preventing pipe 11 positioned on the transversal partitioning 5a, however, there is only one dewing preventing pipe on the transversal partitionings 5a, 5b whereby the amount of heat, invading into the casing of the refrigerator through a forming member 14, becomes one half of the amount of dissipating heat when two of the dewing preventing pipes are arranged in parallel. Accordingly, thermal affection, affected into the case of the refrigerator, may be reduced to one half naturally and efficient cooling effect may be obtained.
