A refrigerator with single system, single fan and multiple temperature zones, including a box shell, an evaporator, a fan, an upper inner tank, an air duct assembly arranged in the upper inner tank, a left freezing chamber shell located at the lower part of the upper inner tank, and a right wide The temperature control cavity shell, the left air duct assembly and the right air duct assembly also include air guides and return air pipes. The air guides are provided with left air inlets, right air outlets and top outlets; In the accommodation cavity, the air guide is arranged between the left air duct cavity and the right air duct cavity, the left air inlet hole is connected with the side air outlet of the fan chamber, and the right air outlet hole is connected with the side air inlet hole of the right air inlet chamber. The ejector air hole is connected with the air inlet chamber of the air duct assembly; the return air groove of the right air duct chamber is fastened with the right return air chamber of the lower inner tank, and the return air groove is connected with the accommodation chamber; the accommodation chamber is connected with the lower inner tank The left return air hole at the lower left is opposite, and the return air pipe connects the return air hole of the refrigerating chamber and the return air hole of the freezing area with the left return air hole. Only one evaporator and one fan are needed to realize multi-temperature zone circulation. Compared with the prior art, the components are reduced and the cost is reduced.
Description
technical field [0001] The invention relates to a refrigerator. Background technique [0002] When the existing refrigerator realizes the multi-temperature zone function, each of the refrigerator compartment and the freezer compartment is provided with a finned evaporator, and multiple cold sources are used to realize the multi-temperature zone function, which requires many design materials and complicated processes. Contents of the invention [0003] The object of the present invention is to provide a refrigerator with single system, single fan and multiple temperature zones, which has the characteristics of one evaporator and one fan, and realizes multi-temperature circulation. [0004] The present invention is achieved in the following way: a refrigerator with single system, single fan and multiple temperature zones, including a box shell, an evaporator, a fan, an upper inner tank, an air duct assembly arranged in the upper inner tank, and a left Freezing chamber shell...
