Problems solved by technology

[0012] In addition, according to the refrigerator disclosed in the above-mentioned Patent Document 2, since the circulation passage, the ascending passage, and the descending passage extending up and down are arranged side by side in the left and right directions on the back of the refrigerating chamber, the widths of the respective flow passages are narrowed.
In order to ensure the volume of the box, the depth of each channel cannot be expanded, thus increasing the ventilation resistance
In addition, since the cold air channel has an ascending channel and a descending channel, the length of the channel becomes longer, which also increases the ventilation resistance
Therefore, the blower efficiency is reduced
In addition, since the channel length of the cold air channel becomes longer, the amount of cold air flowing in the cold air channel released to the outside increases, which also reduces the cooling effect.

Embodiment 1

[0197] Embodiments of the present invention will be described below. Table 1 shows the results of measuring the ion distribution of the refrigerator 1 according to the above-mentioned embodiment. The measurement positions in the up-down direction refer to four locations constituted by each layer divided by the three carriers 41 . The measuring positions in the front-back direction refer to two positions on the front side (70 mm from the front end of the carrier 41 ) and the inside (70 mm from the back wall of the refrigerator compartment 2 ). The measurement positions in the left-right direction refer to the three positions of the left end (70 mm from the left wall of the refrigerator compartment 2), the center, and the right end (70 mm from the right wall of the refrigerator compartment 2). In addition, the horizontal width of the refrigerator 1 is 685 mm.

Abstract

A refrigerator is provided with a storage chamber (2) for housing stored items, a back plate (42) that covers the back surface of the storage chamber (2) from left to right, a condenser (11) for generating cold air, a cold air pathway (32) for circulating the cold air generated by the condenser (11) in order to send the cold air into the storage chamber (2) via first outlets (73a-73c, 74a-74c), a circulation pathway (81) for circulating the cold air in the storage chamber (2) using a circulation blower (85) without going through the condenser (11), and an ion generator (86) that is provided in the circulation pathway (81). The cold air pathway (32) and the circulation pathway (81) are provided to the rear of the back plate (42) of the storage room (2) from left to right.

Description

technical field [0001] The invention relates to a refrigerator. Background technique [0002] Patent Document 1 (Japanese Patent Laid-Open Publication No. 2007-170781 (pp. 5-13, figure 2 )) A conventional refrigerator is disclosed. The refrigerator is provided with a cold air passage at the back of the refrigerating chamber, and the cold air passage is branched toward the left and right, and a circulation passage is arranged between the left and right cold air passages. A cold air outlet is provided on the cold air passage, and the outlet opens toward two outer sides and one side of the center, and the cold air flows from the outlet to the outer side and one side of the circulation passage. In front of the circulation channel, a plurality of suction ports are arranged side by side in the up and down direction. [0003] An ion generating unit having an ion generating device is arranged above the circulation channel in the upper part of the refrigerator compartment. The io...
