Description

Technical Field

[0001] The invention belongs to the technical field of refrigeration, and in particular relates to a vertical refrigerator. Background Art

[0002] Vertical freezers are commonly found in shopping malls, supermarkets, hotels and other business places. They usually have glass doors and place beverages, food and other items inside the freezer. Consumers can directly observe the storage situation inside the freezer and open the door to take them out.

[0003] Existing vertical freezers usually install an air outlet plate on the rear wall of the cabinet body, and multiple air outlets are arranged at different positions on the air outlet plate, so that the cold air flowing out of the air outlet can be diffused into the entire refrigeration cavity of the cabinet body and achieve temperature balance in the cabinet, so as to make the refrigeration effect of items at different positions in the cabinet have good consistency. However, this design scheme of existing vertical freezers can easily lead to the items near the air outlet on the rear wall of the inner tank cooling faster and lower temperature, while the items near the door body cool slower and have higher temperature, so the temperature balance in the cabinet is relatively poor; moreover, when consumers take items in the cabinet, they usually take the items in the front row directly, and the temperature of the items in the front row is relatively high, which fails to achieve the expected refrigeration effect, resulting in a poor consumer experience.

[0046] refer to Figure 1-Figure 17 As shown, the present invention provides a vertical refrigerator, which includes a cabinet body 1, a door body 2 and an air duct assembly 6.

[0047] The cabinet body 1 has an inner container 11 with a front opening, and the inner container 11 includes a container rear wall 111 at the rear, a container top wall 112 at the top, a container bottom wall 115 at the bottom, a container left wall 113 at the left side, and a container right wall 114 at the right side. The inner container 11 is used as a refrigeration chamber 102 of the upright refrigerator. The door body 2 is rotatably connected to the front opening of the cabinet body 1, and is used to close or open the refrigeration chamber 102.

[0048] The air duct assembly 6 includes a top air outlet plate 64, a rear air outlet plate 62 connected up and down, and an air inlet plate 61. The top air outlet plate 64 covers and is connected to the gallbladder top wall 112, and a top air duct 105 is formed between the top air outlet plate 64 and the gallbladder top wall 112. The rear end of the top air outlet plate 64 is connected to the upper end of the rear air outlet plate 62, and the lower end of the air inlet plate 61 is connected to the gallbladder bottom wall 115; the rear air outlet plate 62 and the air inlet plate 61 cover and are connected to the gallbladder rear wall 111, so as to form a rear air duct between the gallbladder rear wall 111. An air duct baffle 63 is connected between the rear air outlet plate 62 and the rear wall 111 of the bladder. Specifically, the air duct baffle 63 is sandwiched between the middle section of the rear air outlet plate 62 and the middle section of the rear wall 111 of the bladder. Through the arrangement of the air duct baffle 63, a rear first air duct 103 is formed between the lower section of the rear air outlet plate 62, the air inlet plate 61, the rear wall 111 of the bladder and the air duct baffle 63, and a rear second air duct 104 is formed between the middle and upper section of the rear air outlet plate 62, the air duct baffle 63 and the rear wall 111 of the bladder, and the rear second air duct 104 is connected to the top air duct 105. The air duct baffle 63 is provided with an air inlet 630 that is through from front to back and centered from left to right. Through the arrangement of the air inlet 630, the rear second air duct 104 is connected to the rear first air duct 103. The space of the inner bladder 11 on the front side of the air duct assembly 6 is the refrigeration chamber 102. An air inlet 610 is provided on the air inlet plate 61 to connect the rear first air duct 103 with the refrigeration chamber 102; a plurality of rear air outlets 620 are provided on the rear air outlet plate 62 to connect the rear second air duct 104 with the refrigeration chamber 102; a front air outlet 640 is provided at the front end of the top air outlet plate 64 to connect the top air duct 105 with the refrigeration chamber 102.

[0049] The evaporator 7 is sandwiched between the rear air outlet plate 62 and the rear wall 111 of the gallbladder in the rear first air duct 103; the evaporator 7 is flat and matches the shape of the rear first air duct 103. The centrifugal fan 8 is arranged in the rear second air duct 104, and the air inlet end of the centrifugal fan 8 is directly opposite to the air inlet 630, that is, the centrifugal fan 8 is sandwiched between the air duct baffle 63 and the rear air outlet plate 62, and is in the middle position in the left and right direction, and the axial direction of the centrifugal fan 8 is the front-to-back direction; it can be understood that the centrifugal fan 8 is a flat volute structure as a whole, and its air inlet end is in its axial direction and the air outlet end is in its radial direction, so the air inlet direction of the centrifugal fan 8 is perpendicular to the rear air outlet plate 62, and the air outlet direction is parallel to the rear air outlet plate 62. The setting of the centrifugal fan 8 changes the airflow direction and realizes 360-degree air outlet in all directions. It should be noted that the arrangement of the rear-mounted centrifugal fan 8 and the evaporator 7 can reduce the space occupied by the fan and the evaporator 7 and increase the storage space in the cabinet.

[0050] The air cooling circulation mode of this embodiment is that the high-temperature air in the refrigerated chamber 102 is sucked into the rear first air duct 103 (i.e., air inlet at the bottom of the cabinet) through the air inlet 610 on the air inlet plate 61 under the action of the centrifugal fan 8, first flows through the evaporator 7 for heat exchange and cooling, and the cooled air flow enters the rear second air duct 104 and the top air duct 105 (i.e., air outlet at the rear of the cabinet and the front end of the top) through the air duct 630 and the centrifugal fan 8, and then enters the refrigerated chamber 102 through the multiple rear air outlets 620 on the rear air outlet plate 62 and the front air outlet 640 on the top air outlet plate 64.

[0051] The above-mentioned schematic embodiment, through the specific design of the air duct component 6, forms an air cooling circulation mode with air intake at the bottom of the cabinet and air outlet at the rear and top front ends, thereby realizing simultaneous air outlets from multiple rear air outlets 620 and front air outlets 640, which can improve the temperature balance in the cabinet; at the same time, through the setting of the front air outlet 640, a wind curtain effect can be formed on the front side of the refrigeration chamber 102, thereby increasing the cooling rate of the items close to the door body 2, so that the items in the front row of the cabinet are cooled first. When consumers take items in the cabinet, they can directly take items with the expected refrigeration effect from the front row, which is more suitable for actual usage scenarios and significantly improves the consumer experience.

[0052] refer to Figure 3 , Fig. 9 , Fig.10 , Fig.15 As shown, in some embodiments, the lower part of the air duct baffle 63 is provided with an air induction portion 633 inclined toward the rear wall 111 of the gallbladder, so that the thickness of the rear first air duct 103 at the air induction port 630 is smaller than the thickness of the rear first air duct 103 at the evaporator 7; the rear air outlet plate 62 is provided with a mounting cavity 625 slightly convex toward the refrigeration chamber 102 at the position corresponding to the centrifugal fan 8, and the centrifugal fan 8 is sandwiched between the air duct baffle 63 and the mounting cavity 625; the airflow after being cooled by the evaporator 7 is accelerated to flow toward the air induction port 630 under the guidance of the air induction portion 633. In this exemplary embodiment, by providing the air induction portion 633 on the air duct baffle 63 and the mounting cavity 625 on the rear air outlet plate 62, the space occupied by the fan is further reduced, the overall structural design of the air duct assembly 6 is made more compact, and the storage space in the cabinet is increased.

The air inlet 610 includes a front air inlet 6111 opened on the front air inlet plate 611, and an upper air inlet 6121 opened on the upper air inlet plate 612. In this exemplary embodiment, by setting the front air inlet 6111 and the upper air inlet 6121 on the air inlet plate 61, it is realized that the air is simultaneously inlet in two directions when the bottom of the cabinet is inlet, which is conducive to improving the air cooling cycle efficiency of the upright freezer.

The rear end of the air guide platform 1121 is connected to the upper end of the air distribution platform 1111, and the left and right sides of the air guide platform 1121 are inclined toward the middle of the front air outlet 640 and meet at the rear of the front air outlet 640.

[0058] In the above-mentioned schematic embodiment, the lower boundary of the rear second air duct 104 is defined by the design of the air guide plate 632, and the cold energy flowing out through the centrifugal fan 8 is guided to diffuse upward rapidly; the cold energy is guided to flow rapidly to the multiple rear air outlets 620 arranged on the left and right through the setting of the air distribution platform 1111; the cold energy is guided to flow smoothly to the front air outlet 640 through the setting of the air guide platform 1121; thereby, waste of cold energy is avoided, which is beneficial to improving the air cooling circulation efficiency of the upright freezer.

[0059] refer to Figure 2 As shown, in some embodiments, a plurality of shelves 9 are installed in the refrigerating chamber 102 of the cabinet 1 to divide the refrigerating chamber 102 from top to bottom into a plurality of refrigerating chambers for storing articles, and the articles are placed on the shelves 9. Usually, the rear air outlet 62 corresponding to the topmost refrigerating chamber and the refrigerating chamber located above the air inlet plate 61 and closest to the air inlet plate 61 does not have a rear air outlet 620. It should be noted that, although the height position of the shelf 9 can be adjusted up and down according to the use needs, the principle of height adjustment is usually set by default to make the height of the air outlet located in the middle and upper part of the refrigerating chamber, that is, the air outlet does not correspond to the lower part of the refrigerating chamber; further explained, because the articles are placed on the shelves 9 of the refrigerating chamber, compared with the lower part of the refrigerating chamber, the space in the middle and upper part of the refrigerating chamber is usually looser, and the cold air flowing out of the air outlet blows to the middle and upper part of the refrigerating chamber, which is more convenient for the diffusion and flow of cold in the refrigerating chamber 102, which is conducive to improving the temperature uniformity in the cabinet.

[0060] refer to Fig.14 , Fig.16 As shown, in some embodiments, the arc-shaped air guide rib 6321 on the air guide plate 632 includes a first arc-shaped rib 6324 and a second arc-shaped rib 6325 located on the left and right sides of the air outlet 630, and the first arc-shaped rib 6324 and the second arc-shaped rib 6325 are arranged in sequence along the rotation direction of the centrifugal fan 8 and are interconnected; the horizontal distance between the upper end of the second arc-shaped rib 6325 and the center of the air outlet 630 is greater than the horizontal distance between the upper end of the first arc-shaped rib 6324 and the center of the air outlet 630, and the radius of the second arc-shaped rib 6325 is greater than the radius of the first arc-shaped rib 6324.
