Description

Technical Field

[0001] The present invention relates to the technical field of cold air circulation refrigeration equipment, and in particular to a horizontal glass door refrigerator with a three-dimensional air circulation device. Background Art

[0002] With the advent of the new retail era, horizontal glass-door freezers are becoming increasingly popular. However, frost formation on the inner liner of traditional horizontal glass-door freezers has long been a problem that affects the consumer experience. Frost formation occurs primarily because the evaporator of direct-cooling freezers is wrapped around the inner liner wall, causing the liner to cool slightly. Moisture in the air liquefies and condenses into frost when it encounters the cold liner wall. Air-cooled frost-free technology offers consumers a more user-friendly cooling experience, with advantages such as better freshness preservation, faster cooling speeds, and greater suitability for large-capacity commercial freezers.

[0003] Conventional freezer cabinets feature a compressor compartment on the right and storage on the left. Current air-cooled freezers on the market have an irrational design of the air ducts within the cabinet, preventing the cooling energy generated by the evaporator unit from effectively entering the air circulation system and exerting its cooling effect within the cabinet. When air circulates to the far left side of the cabinet, there is often a significant pressure drop in the duct, resulting in insufficient air pressure. This leads to uneven cooling distribution on the left side of the cabinet, resulting in temperatures not meeting cooling requirements. Consequently, most products can only meet the cooling requirements of climate type 3 (i.e., an ambient temperature of 25 degrees Celsius and a humidity of 60%), significantly limiting their application.

[0004] Most existing horizontal glass-door freezers use single-layer tempered glass for their doors, with a few using plastics like acrylic. These materials have high thermal conductivity, making it easy for cold air inside the cabinet to transfer to the exterior. This causes moisture in the air to liquefy and form condensation. This poor thermal insulation also increases power consumption and reduces reliability.

[0005] Therefore, those skilled in the art are in urgent need of an air-cooled circulating refrigerator that can solve the problems of uneven cold air distribution inside the air-cooled glass refrigerator, easy frost on the glass door, and display failure. Summary of the Invention

DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is described below in conjunction with specific implementation methods and drawings.

[0031] In this technical solution, in order to solve the problem of uneven air cooling circulation inside the refrigerator, by analyzing the relationship between the air duct structure parameters and air volume distribution and pressure drop loss, based on the principle of air volume distribution on demand, the specific layout position of the air duct structure is obtained, and a three-dimensional air cooling circulation solution is proposed.

[0032] To address the problem of uneven air cooling circulation inside the freezer, a bionic structure design is adopted in the three-dimensional air cooling circulation duct. By setting up guide baffles and streamlined design, the uniformity of air outlet on the left and right sides of the box is ensured.

[0033] To address the issues of condensation on the door body and display failure, one approach is to use curved hollow glass door insulation technology. The curved hollow glass is fixed and sealed with a frame with insulation function, and the glass interlayer is filled with inert gas. The low thermal conductivity of the inert gas is used to ensure that the outer glass is always above the dew point temperature, thereby reducing power consumption.

[0034] To address the problems of condensation on the door body and display failure, a grille structure is installed on the outer cover of the three-dimensional air-cooling circulation duct. The grille is used to guide the wind direction, so that the cold air is not blown directly to the glass above, reducing the cold conduction of the glass.

[0035] To address the problems of condensation on the door body and display failure, the third approach is to design a door body equipped with an elastic sealing slider. The traditional door frame and the cabinet opening are in hard contact with poor sealing, resulting in serious cold loss. The elastic sealing slider is used to achieve soft contact between the door body and the cabinet opening, further enhancing the sealing performance, reducing the cold conduction of the glass, and reducing power consumption.

[0036] like Figure 1-13 As shown, a horizontal glass door refrigerator with a three-dimensional air circulation device includes an outer cabinet body 10, an inner tank component 20, an air duct structure 30, and a refrigeration system 40. The refrigeration system includes a cold air outlet 401 and a return air inlet 402. The direction of the arrow in the figure indicates the direction of cold air flow.

[0037] The inner tank assembly includes an inner tank body 21 and an upper cabinet opening 22. The cabinet opening comprises a counter 221 and a snap-fit ​​structure located below the counter opening. The snap-fit ​​structure snaps onto the outer cabinet and inner tank. The cavity formed by the outer cabinet, inner tank, and cabinet opening is foamed with polyurethane to form a stable structure. The counter is equipped with a curved glass door 23. A refrigeration compartment 24 is located to the lower right of the inner tank assembly, housing the refrigeration system.

[0038] The curved glass door body includes an upper curved glass 231, a lower curved glass 232, and a fixed sealing strip 233. The fixed sealing strip is arranged at the edges of the upper curved glass and the lower curved glass. A glass cavity 234 is formed between the upper curved glass, the lower curved glass, and the fixed sealing strip. The glass cavity is filled with inert gas. The fixed sealing strip seals the frame 235, a connector 236, and an elastic sealing slide 237. The sealing frame is arranged between the upper curved glass and the lower curved glass. The elastic sealing slide is arranged between the lower glass body and the counter body. The connector connects the sealing frame and the elastic sealing slide. The elastic sealing slide includes an elastomer. The outer surfaces of the elastomer and the connector are provided with wave patterns 238. The sealing slide is made of a synthetic material with excellent wear resistance and elasticity.

[0039] The air duct structure includes an air duct cover 31, an air supply duct 32, and a return air duct 33. The air duct assembly cooperates with the special-shaped holes on the inner bladder body through a buckle structure, and the assembly gap between the air duct assembly and the inner bladder body is reinforced with sealing tape or the like.

[0040] The air supply duct includes an air inlet duct 321 and an air supply duct section 322. The air supply duct section is composed of a plurality of independent air supply duct assemblies. The independent air supply duct assemblies are connected in series via the snap-fit ​​structure thereon. The air supply duct is provided on the outside of the inner liner component and is arranged on three surfaces, namely the front, left and back of the inner liner body, with a symmetrical distribution on the front and back. The air supply duct is provided with a cold air inlet 323 on the upper part of the inner liner component. The upstream of the air supply duct is connected to the cold air outlet of the refrigeration system, and the end is connected to the duct cover. The main function of the air supply duct is to introduce the cold energy generated by the refrigeration cycle system into the air duct, and to transfer the cold energy to the required location through the air duct. The air supply duct and the inner liner body are assembled through a snap-fit ​​structure.

[0041] The air inlet duct includes a bionic structure in the shape of a snail shell. A centrifugal fan 324 is installed within the lower circumference of the snail shell. When the centrifugal fan is working, the motor drives the impeller to rotate. The blades in the impeller force the gas to rotate, doing work on the gas and increasing its energy. Under the action of centrifugal force, the gas is thrown out to the surrounding of the impeller. The volute can be regarded as a channel for air flow. It can collect and guide the gas leaving the centrifugal fan impeller so that the air flow entering the air duct can be evenly introduced into the air duct mechanism along the streamlined structure 325 on the volute. As the cross-section of the volute increases, the speed of the air flow gradually decreases. At this time, part of the kinetic energy in the air flow is converted into static pressure, which is equivalent to the conversion of velocity energy into pressure energy. The generation of wind pressure enables the air flow to reach the desired air duct outlet position. When the gas in the impeller is discharged, the pressure inside the impeller is lower than the pressure inside the air inlet. New gas is sucked into the impeller under the action of the pressure difference, and the gas is continuously discharged from the outlet.

[0042] A guide baffle 34 is set inside the air inlet duct to divert cold air, and the air supply duct is set downstream of the guide baffle. Since the air volume required on the right side of the box is greater than the air volume required on the left side of the box, the installation position of the baffle is obtained by analyzing the relationship between the duct structure and the air volume distribution and pressure drop loss to ensure the uniformity of air outlet on the left and right sides of the box.

[0043] The guide baffle includes an arc-shaped top 341, and a first arc-shaped plate 342 and a second arc-shaped plate 343 arranged on both sides of the arc-shaped top. The arc-shaped top faces the direction of the centrifugal fan, and the air volume of the air supply duct connected to the first arc-shaped plate is greater than the air volume of the air supply duct connected to the second arc-shaped plate.

[0044] There are two groups of air supply ducts on the front and back sides of the cabinet, including a front air duct, a rear air duct, and a left air duct for connecting the front air duct and the rear air duct. The front air duct and the rear air duct are symmetrically arranged. The front air duct includes a long end and a short end of the air duct. The long end of the air duct is connected to the air supply duct part connected to the first curved plate, and the short end of the air duct is connected to the air supply duct part connected to the second curved plate.

[0045] The guide baffle further includes a baffle adjuster 35 for adjusting the position of the guide baffle. The baffle adjuster is disposed in a baffle cavity 36 formed by the arc-shaped top, the first arc-shaped plate and the second arc-shaped plate.

[0046] The partition adjuster includes a connecting rod 351, a fixing ring 352, an adjustment spring 353, an adjustment block 354, a base 355, and a base spring 356. The connecting rod is installed between the first curved plate and the second curved plate. An adjustment cavity 357 is provided in the middle position of the connecting rod. The fixing ring is fixed on the inner tank component. The fixing ring is sleeved on the outer side of the connecting rod. The adjustment block is a wedge-shaped block with a wedge-shaped surface. The bottom of the adjustment block is placed on the base. The base spring is arranged between the wedge-shaped block and the base. The top of the adjustment block is provided with a chamfered corner 358. The top of the adjustment block passes through the adjustment cavity and extends out of the counter body to contact the curved glass door body. The adjustment spring includes a first spring 3531 and a second spring 3532. The first spring is provided on one side of the wedge surface of the adjustment block, and the second spring is provided on one side of the vertical surface of the adjustment block. The first spring is sleeved on the outer side of the connecting rod, one end is fixedly connected to the connecting rod, and the other end is connected to the wedge surface. A second spring is sleeved onto the outside of the connecting rod, with one end fixedly connected to the fixing ring and the other end fixedly connected to the connecting rod. The adjustment spring can be fixed in an adjustment cavity, and a spring cavity is further provided in the adjustment wall. When the curved glass door body on the side with less air volume is opened, the curved glass door body releases the pressure on the adjustment block, and the adjustment block is pushed upward by the base spring. At the same time, due to the action of the wedge-shaped surface, the adjustment block set in the adjustment cavity of the connecting rod applies pressure to the first spring. The first spring, which is fixedly connected to the connecting rod, pushes the connecting rod to move within the fixing ring, thereby pushing the entire guide baffle to move, increasing the space on the side of the second curved plate, thereby increasing the cold air flow on the second curved plate side. At this time, the second spring is stretched. When the curved glass door body is closed, the curved glass door body, under the action of the wedge-shaped surface and the rounded corners, presses the adjustment block downward, and the entire adjustment block is pressed down. The external force of the first spring is released, and the second spring retracts, pulling the connecting rod back to its original position, and the guide baffle returns to its original position.

[0047] The air duct cover is arranged on the inner side of the inner tank body, and a grille structure 311 for air flow guidance is provided on the air duct cover. The air duct cover is composed of a plurality of independent covers, and the independent covers are connected in series through the snap-on structure thereon. The air duct cover is arranged on the front, left and back sides of the inner tank body, and is symmetrically distributed on the front and back sides. The main function of the air duct cover is to be the outlet of the cold energy in the refrigeration cycle system and to guide the flow direction of the cold energy. The grille divides the air outlet into 3×3 equal parts, and the angle of the grille guide vane is 45°. By guiding it obliquely downward, the cold energy is not blown directly to the glass above, thereby reducing condensation on the glass.

[0048] The return air duct is composed of a plurality of independent return air duct assembly components 331 and return air outlets 332. It includes a distal return air structure and a proximal return air structure, and the independent return air duct assembly components are connected in series through the snap-on structure thereon. The return air duct is arranged on three surfaces, namely the front, right and back of the inner tank body. The front and back are symmetrically distributed as the distal return air structure of the return air duct, including a return air duct part and a distal return air outlet. The distal return air outlet is arranged at the bottom of the inner tank component and opens into the inner tank component. An air duct cover is arranged on the outside, and the end of the return air duct part is connected to the return air inlet of the refrigeration system. The proximal return air structure is strip-shaped and is arranged at the inner tank component close to the refrigeration system. The main function of the return air duct is to return the cold transferred from the air duct cover to the refrigeration system through the circulation in the box to restart the refrigeration cycle. The return air duct on the right and the supply air duct on the left form convection, which enhances the three-dimensional degree of cold air in the inner tank. When returning on the right side, it is close to the refrigeration system and can be directly reused to reduce energy loss.

[0049] like Figure 10 As shown in the cold air temperature distribution, it can be seen that when the cold air circulates in the cold air three-dimensional air cooling cycle, the refrigeration system is installed on the lower right side of the box. The cold energy generated by the refrigeration system first passes through the centrifugal fan installed above the air inlet duct in the supply air duct, and the air inlet duct adopts a volute design. When the centrifugal fan is working, it drives the cold air along the streamlined structure on the left side and enters the supply air duct through the air inlet duct guide baffle on the upper right side. Since the air volume required on the right side of the box is greater than the air volume required on the left side of the box, the air volume distribution on the left and right sides is adjusted by the installation position of the baffle. After the supply air duct introduces the cold energy into the air duct and transmits it to the required position through the air duct, the cold energy is guided downward at a 45-degree angle along the grille guide plate through the air duct cover on the upper part of the inner tank body to the inside of the box. The air duct cover is arranged on the front, left and back of the inner tank body, with a symmetrical distribution on the front and back. After the cooling air is cooled within the cabinet, a portion of the air is directed to the refrigeration system on the lower right side of the cabinet, while the air in the lower left side of the cabinet returns to the refrigeration system via a return air duct located below the inner liner. This return air duct design effectively addresses the issue of substandard storage temperature for goods in the lower left side of the cabinet. The refrigeration system, centrifugal fan, supply air duct, duct cover, and return air duct together form a three-dimensional cooling loop. Circulating wind speed simulation ensures a relatively uniform wind speed within the duct, effectively improving the uneven cooling loop.

[0050] Sealing strips are affixed to the sides of the glass door, and the door is mounted on a step formed by the upper opening of the liner, creating a sliding glass door freezer. Because the traditional door frame and opening form a hard contact with poor sealing, resulting in significant cooling loss, the use of sealing strips creates a softer contact between the door and opening, further enhancing sealing performance, reducing cooling loss through the door during the refrigeration cycle, and reducing condensation on the door.

[0051] The above embodiments are intended only to illustrate the inventive concepts and features of the present invention. Their purpose is to enable those skilled in the art to understand the present invention and implement it accordingly. They are not intended to limit the scope of protection of the present invention.
