The present invention will be described in detail below in conjunction with specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, method, or functional changes made by those skilled in the art according to these embodiments are included in the protection scope of the present invention.

Referring to Fig. 1, Fig. 2, and Fig. 3, a specific embodiment of the soft freezing chamber of the refrigeration device of the present invention is introduced. In this embodiment, the soft freezing chamber 100 of the refrigeration device includes an inner container 10 with an open front end; The evaporator 30 fits the inner container 10 and is used to control the temperature of the soft freezer 100 . Wherein, the liner 10 can be fixedly arranged in the soft freezer 100, and can also be drawn along the front and back direction of the soft freezer 100; The evaporators are arranged in series; due to the connection relationship between the liner 10 in the soft freezer 100 and the soft freezer 100, and the connection relationship between the evaporator 30 in the soft freezer 100 and the evaporator in the refrigerator and/or freezer, it does not involve The technical points of the present invention will not be repeated in this embodiment.

It should be noted that the refrigerating device mentioned here may include common refrigerating devices such as refrigerators, freezers, and refrigerated wine cabinets.

In a preferred embodiment of the present invention, the above-mentioned inclined wall includes a left inclined wall 105 a connected between the top wall 107 and the left side wall, and a right inclined wall connected between the top wall 107 and the right side wall 103 b 105b, a left intersection line 111a is formed between the left side wall and the left inclined wall 105a, and a right intersection line 111b is formed between the right side wall 103b and the right inclined wall 105b.

Preferably, the liner 10 is mirrored along its central axis.

Correspondingly, the top wall 107 is arranged parallel to the bottom wall, and the area of the top wall 107 is smaller than that of the bottom wall, so as to form an angled left inclined wall between the top wall 107 and the bottom wall 105a, right inclined wall 105b.

Correspondingly, the left side wall is parallel and mirrored with respect to the right side wall 103b, and the planes of the left side wall and the right side wall 103b are perpendicular to the planes of the top wall 107 and the bottom wall at the same time, so as to facilitate the The angles formed by the inclined wall 105a and the right inclined wall are the same.

Correspondingly, a first included angle α is formed between the left side wall and the left inclined wall 105a, and an included angle same as the first included angle α is formed between the right side wall 103b and the right inclined wall 105b.

Correspondingly, a second included angle β is formed between the left inclined wall 105a and the top wall 107, and an included angle same as the second included angle β is formed between the right inclined wall 105b and the top wall 107.

Correspondingly, the first included angle α and the second included angle β are double obtuse angles, thereby forming an inner container 10 with an isosceles trapezoidal structure at the top. It can be understood that, according to the principle that the hot air rises and the cold air sinks, the evaporator 30 fitted with such a structure can dissipate cold energy along the left inclined wall 105a to the left side wall, and the bottom Wall, the inner tank storage area, finally to the top wall 107, and along the right inclined wall 105b to the right side wall 103b, the bottom wall, the inner tank storage area, and finally to the top wall 107 form a closed cold air exchange loop, through the cold air The natural convection achieves cooling effect.

Preferably, the value of the first included angle α is 150 degrees, and the value of the second included angle β is 120 degrees. In this way, the space of the liner 10 can be utilized to the maximum, so that the left inclined wall 105a and the right inclined wall 105b are not set. The internal storage space of the liner 10 is excessively wasted.

Preferably, the distance from the left intersection line 111a and the right intersection line 111b to the plane where the top wall 107 is located is smaller than the distance to the plane where the bottom wall is located. It can be understood that the user of the refrigeration device usually places the storage items at the bottom of the inner tank 10 habitually, and seldom utilizes the space at the top of the inner tank 10, so the left inclined wall 105a and the right inclined wall 105b are arranged on the inner tank 10 The upper position inside will satisfy the operator's usage habits, and the inner space of the liner 10 will also be well utilized.

It can be understood that, in other embodiments of the present invention, considering that the temperature of the part closer to the opening of the inner container 10 in the soft freezing compartment 100 is also relatively high, therefore, the left inclined wall 105a and the right inclined wall 105a can be further optimized. The width of the inclined wall 105b is set to gradually decrease from the opening of the inner container 10 to the direction extending to the rear wall 107, so that the evaporator 30 configured on it will have a larger evaporation area near the opening, so that the soft freezer The temperature in the 100 is more uniform, ensuring the cooling effect of the soft freezer 100.

Correspondingly, the distance from any point on the intersection line of the left inclined wall 105a, right inclined wall 105b and the left side wall and right side wall 103a to the plane where the top wall 109 is located is less than the distance from it to the bottom wall The distance of the plane where 103 is located.

In a specific embodiment of the present invention, the evaporator 30 is a tube-plate evaporator, and the evaporator 30 is fitted on the left inclined wall 105a and the right inclined wall 105b, which includes two sub-evaporators 31 arranged in series, and the two sub-evaporators The evaporators 31 are connected by a connecting pipe 33; the sub-evaporator 31 includes a heat exchange plate 311, which is used to increase the evaporation area; Evaporation pipe 313, the evaporation pipe 313 is arranged in a serpentine shape to obtain a larger evaporation area.

Preferably, the evaporation areas of the two sub-evaporators 31 are the same, so as to ensure the same cooling effect on both sides of the inner container 10 .

Correspondingly, the materials of the heat exchange plate 311 and the evaporating tube 313 are not particularly limited, generally aluminum, copper and other materials are used.

Correspondingly, the shape of the heat exchange plate 311 is not particularly limited, and may be in various shapes such as square, rectangle, triangle, and trapezoid.

Correspondingly, the shape of the evaporating tube 313 is not particularly limited, and the evaporating tube 313 can be set as a straight tube. The advantage of this structure setting is that the material of the evaporating tube 313 is the most economical and cost-saving, but at the same time, the emitted The evaporation area is also the smallest; the evaporation tube 313 can also be arranged in coils, such as serpentine, square, triangular, trapezoidal and other structures. Compared with setting it as a straight tube structure, this structure will use more materials and cost increase, but the evaporation area will increase accordingly. No matter which structure is adopted, it is enough to ensure that the evaporation areas of the two evaporation tubes 313 are the same.

Preferably, the two sub-evaporators 31 are mirror images of each other, and are only arranged on the inclined walls 105a, 105b. According to the principle that hot air rises and cold air sinks, the cold energy emitted by it can go along the left inclined wall 105a to the left side wall, the bottom wall, the storage area of the inner tank, and finally to the top wall 107, and From the right inclined wall 105b to the right side wall 103b, the bottom wall, the storage area of the liner, and finally to the top wall 107 form a closed cold air exchange loop, and the cooling effect is achieved through the natural convection of the cooling capacity, so as to solve the problem of being placed in the soft freezer The cold source provided by the evaporator 30 in the 100 is concentrated, which leads to the problem of uneven temperature distribution in each area of the soft freezing chamber 100 .

Correspondingly, the heat exchange plate 313 attached with the evaporator tube 311 forms an included angle with the plane where the top wall 107 is located and the plane where the left side wall and right side wall 103b are located, so as to facilitate the sub-evaporator 31 to fit the inclined walls 105a, 105b set up.

Correspondingly, the angle formed by the heat exchange plate 313 and the plane where the top wall 107 is located has the same value as the first angle α, and the angle formed by the heat exchange plate 313 and the plane where the left side wall 103 and the right side wall 103b are located is equal to The value of the second included angle β is the same.

Preferably, the evaporation area of the connecting pipe 33 is smaller than the evaporation area of the sub-evaporator 31, so as to facilitate the natural convection of cooling capacity in the storage space of the liner.

In particular, the connecting pipe 33 is arranged on the top wall 107 of the inner container 10, and is arranged near the open side of the front end of the inner container 10; , when taking and placing the article on its inner side, hot air will first enter into the open side of the front end of the inner container 10, so the temperature on the open side of the front end is higher than the temperature on the open side of the front end of the inner container 10. The connection pipe 33 is arranged on the top wall 107 of the inner tank 10, and is arranged close to the open side of the front end of the inner tank 10, so as to provide an extra layer of protection in the area with a high temperature of the inner tank 10, so as to reduce the temperature difference between the front and rear of the inner tank 10 , and furthermore, under the action of the evaporator 30, the problem of large temperature difference among the inner tank 10 is solved.

Correspondingly, the connecting pipe 33 can be arranged as a straight pipe. The advantage is that the manufacturing material of the connecting pipe 33 is the most economical, which can save costs, but at the same time, its evaporation area is correspondingly the smallest; , triangular and other structures, this structure will use more materials than setting it as a straight tube structure, and the cost will increase, but its evaporation area will also increase accordingly.

Referring to Fig. 4 and Fig. 5, another specific embodiment of the soft freezing compartment of the refrigeration device of the present invention is introduced. The difference from the above embodiment is that in this embodiment, the evaporator 30 includes two sub-evaporators arranged in parallel The two sub-evaporators 31 are independently arranged on the left inclined wall 105a and the right inclined wall 105b. It can be understood that in this way, according to the principle that hot air rises and cold air sinks, the cold energy emitted by the evaporator 30 can reach the left side wall, the bottom wall, and the inner tank along the left inclined wall 105a. The storage area, finally to the top wall 107, and along the right inclined wall 105b to the right side wall 103b, the bottom wall, the inner tank storage area, and finally to the top wall 107 form a closed cold air exchange loop, which is achieved by natural convection of cold The cooling effect is to solve the problem of uneven temperature distribution in each area of the soft freezing room 100 due to the concentrated cold source provided by the evaporator 30 arranged in the soft freezing room 100 .

Correspondingly, the present invention also provides a refrigeration device (not shown in the figure), which can obtain the beneficial effects of the soft freezing chamber 100 in the above embodiments by adopting the soft freezing chamber 100 of the refrigeration device introduced in the above embodiments. effect, and since no improvement has been made to other structures or functions of the refrigeration device, other structures of the refrigeration device will not be repeated here.
