Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment, specifically to a double-sided promotional island display cabinet with non-condensing and uniform cooling. Background Technology

[0002] The air-cooled double-sided promotional island display cabinet features symmetrical vertical transparent display ends on both sides, meeting the needs of consumers to simultaneously display products from the left, right, and top sides.

[0003] In existing technology, double-sided island refrigerators are generally divided into two storage compartments, left and right, by a central platform. For example, Chinese utility model patent CN202120436965.0 discloses a simple air-cooled double-sided island refrigerator, including a refrigerator body with a platform in the middle. An evaporator is installed in the internal cavity of the platform. The internal cavity of the refrigerator body is divided into a left storage compartment and a right storage compartment by the platform. Trays are provided at the bottom of both the left and right storage compartments. Air outlets connected to the evaporator are provided at the top of both the left and right storage compartments. Return air grilles and blower devices connected to the evaporator are provided inside both the left and right storage compartments. A base frame is provided at the bottom of the refrigerator body, and a compressor compartment is provided inside the base frame. The compressor compartment contains a compressor and a condenser.

[0004] However, the display requirements for double-sided island cabinets are diverse. Some display requirements require the double-sided island cabinet to have only one flat storage space. Therefore, the scheme of arranging the evaporator in the middle platform in the aforementioned public documents can no longer be used. For display requirements that require a single, flat storage space in the double-sided island cabinet, the existing technology generally adopts the scheme of bottom air outlet of the refrigerator storage compartment, which results in uneven cooling inside the cabinet and cannot achieve uniform cooling. Moreover, the cold air blowing directly on the outer windshield can easily cause condensation.

[0005] Therefore, people have been seeking an ideal technical solution for designing a double-sided promotional island display case with a single, flat storage space, whose cooling system can deliver air evenly, while also preventing condensation on the outer glass. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by providing a double-sided promotional island cabinet with non-condensing and uniform cooling. It is designed with a single, flat storage space inside the cabinet, which can evenly distribute cold air into the storage room through the air guide plate and the perforated plate, and can prevent the cold air from causing condensation on the baffle plate.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: It includes a cabinet, inside which is a storage platform. The upper and lower sides of the storage platform are respectively configured as a storage chamber and an evaporator chamber. The storage chamber is connected to the air outlet side and air return side of the evaporator chamber via vertical transparent display ends on its left and right sides, respectively. The vertical transparent display end connecting to the air outlet side of the evaporator chamber includes a baffle plate, a guide plate, and a perforated plate for air distribution, arranged from the outside to the inside. An air inlet channel is formed between the guide plate and the perforated plate. The bottom of the air inlet channel is connected to the evaporator chamber, and the air inlet channel is connected to the storage chamber through air distribution holes on the perforated plate.

[0008] In this application, since the vertical transparent display ends on both sides of the storage compartment can be used for air intake and exhaust respectively, and the cold air passes directly above the shelf platform and forms a circulation, the storage compartment can serve as a single, flat storage space within a double-sided island cabinet to meet display needs. Because the cold air blown out from the evaporator chamber enters the storage compartment through the air intake channel and the air distribution holes on the perforated plate, the cold air in the air intake channel can be dispersed into multiple streams, ensuring that the cold air blowing towards the displayed goods in the storage compartment is evenly distributed, avoiding concentrated or insufficient cold air volume. By using an air guide plate located inside the baffle to direct the air towards the perforated plate further inward, cold air is prevented from blowing directly onto the baffle, effectively preventing condensation on the outside of the baffle.

[0009] Based on the above, the top of the air guide plate is provided with an air guide wing plate, the top of the perforated plate is provided with an air distribution wing plate, the air guide wing plate extends into the interior of the storage chamber, the end of the air distribution wing plate extends towards the surface of the air guide plate, and the air distribution wing plate is provided with wing plate air distribution holes facing the air guide wing plate.

[0010] The air guide vanes can redirect the cold air passing through the top of the air intake channel to the inside of the storage room, and the air distribution vanes can ensure that the cold air is evenly distributed before it comes into contact with the air guide vanes, thus avoiding the concentration or dispersion of cold air.

[0011] Based on the above, the air guide plate is inclined towards the storage chamber around its bottom edge, and the perforated plate is vertically arranged.

[0012] The inclined air guide plate can achieve a better air guiding effect, allowing the cold air to contact the perforated plate more evenly; the vertically set perforated plate can make the cold air blow horizontally to the opposite side, avoiding the cold air blowing directly onto the top glass and causing condensation.

[0013] Based on the above, the end of the air guide vane is bent downward to form an air guide groove, and the air holes of the vane all face the inside of the air guide groove.

[0014] By using air guide channels, the air distribution holes on the wing panels are directed towards the inside of the air guide channels, preventing cold air from blowing directly onto the top glass of the cabinet and thus preventing condensation.

[0015] Based on the above, both the air guide plate and the perforated plate are integral acrylic sheets.

[0016] Using acrylic material facilitates the forming of air guide plates and perforated plates.

[0017] Based on the above, the air distribution holes on the surface of the porous plate are waist-shaped holes arranged horizontally along the long axis.

[0018] The waist-shaped perforated air distribution holes facilitate efficient guidance of cold air to the outlet even when it is dispersed evenly.

[0019] Based on the above, the vertical transparent display end connected to the return air side of the evaporator chamber includes another set of the baffle plate, the air guide plate, and the perforated plate arranged from the outside to the inside.

[0020] The perforated plate installed on the return air side of the evaporator chamber facilitates the uniform convergence of cold air. The air guide plate can effectively guide the cold air into the evaporator and prevent the cold air from blowing directly onto the baffle plate, thus avoiding condensation.

[0021] Based on the above, the cabinet is provided with a bottom plate, and the bottom plate is provided with a suction fan and an evaporator. The evaporator chamber is formed between the bottom plate and the storage platform.

[0022] The bottom plate of the boat not only effectively supports the suction fan and evaporator, but also allows the evaporator chamber to form an independent space to prevent the cold air from escaping, while also effectively collecting condensate.

[0023] Based on the above, the bottom of the cabinet is provided with a base frame, and the base frame is provided with a compressor chamber, which is provided with a condenser and a compressor.

[0024] The base frame at the bottom of the cabinet not only effectively supports the storage platform and the bottom plate of the boat, but also effectively provides heat dissipation space for the condenser and compressor.

[0025] Based on the above, the cabinet also includes a defogging mechanism for defogging the outer surface of the wind deflector. The defogging mechanism includes a defogging duct located on one side of the cabinet. The inlet end of the defogging duct is connected to the compressor chamber via a defogging fan, and the outlet end of the defogging duct is located outside the wind deflector outside the air inlet channel.

[0026] By using a defrosting fan and defrosting duct, the heat generated by the condenser and compressor inside the compressor chamber is blown towards the outer side of the baffle plate. This not only dissipates heat from the compressor chamber but also effectively uses the hot air to maintain the temperature of the baffle plate, thus preventing condensation.

[0027] In summary, the double-sided promotional island display case of this application not only features a single, flat storage space within the cabinet to meet corresponding display needs, but also incorporates a three-layer structure of a baffle plate, a guide plate, and a perforated plate within the vertical transparent display ends on both sides of the cabinet. This allows the storage chamber and evaporator chamber, separated by the storage platform, to be connected via the air intake channel between the guide plate and the perforated plate. The guide plate and perforated plate can evenly distribute cold air into the storage chamber, and the guide plate can prevent condensation on the baffle plate caused by cold air.

[0030] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0031] Example 1 like Figures 1-3 As shown, the double-sided promotional island display cabinet with non-condensing and uniform cooling in this embodiment includes a cabinet body, and a storage platform 1 is provided inside the cabinet body. The storage platform 1 is used to place and display products. The storage platform 1 and the vertical transparent display ends on both sides together form the storage chamber 101 of the double-sided island display cabinet. The upper and lower sides of the storage platform 1 are respectively provided as the storage chamber 101 and the evaporator chamber 102. The storage chamber 101 is connected to the air outlet side and the air return side of the evaporator chamber 102 through the vertical transparent display ends on the left and right sides, respectively. That is, the vertical transparent display ends on the left and right sides of the double-sided island display cabinet are used for the air outlet and air return of the evaporator chamber 102, respectively.

[0032] Because the outlet air temperature of the evaporator chamber 102 is low, direct contact of cold air with the outer baffle glass can easily cause the outer baffle glass to become cold, causing moisture in the outside air to condense on the outer surface of the outer baffle glass. Therefore, in this embodiment, the vertical transparent display end connected to the outlet side of the evaporator chamber 102 includes a baffle plate 2, a guide plate 3, and a perforated plate 4 for uniform airflow, arranged from the outside to the inside. The guide plate 3 contacts the cold air in advance and guides the cold air into the storage chamber 101, preventing the cold air from blowing directly on the baffle plate 2, which serves as the outer baffle glass, and causing condensation on its outer surface. An air inlet channel is formed between the guide plate 3 and the perforated plate 4. The bottom of the air inlet channel is connected to the evaporator chamber 102, and the air inlet channel is connected to the storage chamber 101 through the airflow equalization holes on the perforated plate 4.

[0033] like Figure 1 , Figure 2 As shown, the arrows in the storage chamber 101 and the evaporator chamber 102 indicate the direction of cold air circulation.

[0034] The air distribution holes can be arranged at equal intervals on the perforated plate 4 to achieve the purpose of air distribution.

[0035] The bottom of the perforated plate 4 can be installed on the storage platform 1.

[0036] The combination of wind deflector 2, air guide plate 3, and perforated plate 4 serves as the vertical transparent display end of the double-sided island cabinet, all made of transparent material. Wind deflector 2, acting as a windshield, can be made of glass or other types of transparent material.

[0037] Since the vertical transparent display ends on both sides of the storage room 101 can be used for air intake and air exhaust of the storage room 101 respectively, and the cold air passes directly from above the storage platform 1 and forms a circulation, the storage room 101 can serve as a single, flat storage space within the double-sided island cabinet to meet display needs.

[0038] Since the cold air blown out of the evaporator chamber 102 enters the storage chamber 101 through the air inlet channel and the air distribution holes on the perforated plate 4, it can disperse the cold air in the air inlet channel into multiple streams, avoid the cold air concentration, and make the cold air blown to the displayed goods in the storage chamber 101 evenly distributed, avoiding the situation where the cold air volume is concentrated in a certain place or the cold air volume is insufficient in a certain place.

[0039] By using a guide plate 3 located inside the wind deflector 2 to direct the airflow to the perforated plate 4 further inside, cold air is prevented from blowing directly onto the wind deflector 2, effectively preventing condensation on the outside of the wind deflector 2.

[0040] Furthermore, the cabinet is equipped with a bottom plate 5, on which an exhaust fan 6 and an evaporator 7 are mounted. An evaporator chamber 102 is formed between the bottom plate 5 and the storage platform 1. The bottom plate 5 not only effectively supports the exhaust fan 6 and the evaporator 7, but also allows the evaporator chamber 102 to form an independent space, thus preventing the loss of cold air and effectively collecting condensate.

[0041] The bottom plate 5 of the boat bottom is lower at the air outlet side of the evaporator chamber 102 than at the air return side, so as to facilitate the collection of condensate; the bottom plate 5 of the boat bottom can be provided with an inclined plate surface that is inclined to connect the bottom of the air guide plate 3 at the air outlet side of the evaporator chamber 102, which further facilitates the collection of condensate.

[0042] Furthermore, a base frame 8 is provided at the bottom of the cabinet, and a compressor chamber 103 is located inside the base frame 8. The compressor chamber 103 contains a condenser 9 and a compressor 10. The base frame 8 at the bottom of the cabinet can not only effectively support the storage platform 1 and the bottom plate 5, but also effectively provide heat dissipation space for the condenser 9 and the compressor 10.

[0043] Example 2 like Figure 2 , Figure 3 As shown, the main difference between this embodiment and Embodiment 1 is that: the top of the air guide plate 3 is provided with an air guide vane, and the top of the perforated plate 4 is provided with an air distribution vane, so that the air guide plate 3 and the perforated plate 4 form an "L" shaped plate. The air guide vane extends into the storage chamber 101, and the end of the air distribution vane extends into the surface of the air guide plate 3. The air distribution vane is provided with air distribution through holes. The air guide vane can redirect the cold air passing through the top of the air inlet channel into the storage chamber 101, and the air distribution vane can ensure that the cold air is uniformly treated before contacting the air guide vane, avoiding the concentration or dispersion of cold energy.

[0044] like Figure 2 As shown, the air guide plate 3 is inclined towards the storage chamber 101 around its bottom edge, and the perforated plate 4 is vertically arranged. The inclined air guide plate 3 can achieve a better air guiding effect, so that the cold air can contact the perforated plate 4 more evenly; the vertically arranged perforated plate 4 can make the cold air blow horizontally to the opposite side, avoiding the cold air from blowing directly onto the top glass and causing condensation.

[0045] like Figure 3As shown, furthermore, the air distribution holes on the perforated plate 4 are arranged in a horizontally spaced, waist-shaped pattern. These waist-shaped holes are evenly spaced horizontally. The long axis of the waist-shaped holes significantly guides and shapes the airflow, creating a laminar flow of cold air in the horizontal direction, which is beneficial for air circulation. Moreover, the evenly spaced waist-shaped holes are more aesthetically pleasing than densely packed round holes, which is advantageous for displaying merchandise from the vertical transparent display end. Therefore, the waist-shaped air distribution holes effectively guide the dispersed cold air to the outlet.

[0046] like Figure 2 As shown, further, the end of the air guide vane is bent downward to form an air guide groove, and the air distribution holes on the air distribution vane all face the inside of the air guide groove, so that the cold air blown by the air distribution holes on the air distribution vane can be guided to the storage platform 1 by the downward bending of the air guide vane, thus preventing the cold air from blowing directly onto the top glass of the cabinet and preventing condensation.

[0047] Furthermore, both the air guide plate 3 and the perforated plate 4 are integral acrylic sheets, which is beneficial for the forming of the air guide plate 3 and the perforated plate 4.

[0048] Example 3 The main difference between this embodiment and Embodiment 1 or Embodiment 2 is that the vertical transparent display end on the return air side of the evaporator chamber 102 includes another set of baffles 2, guide plates 3, and perforated plates 4 arranged from the outside to the inside. A return air channel is formed between the guide plates 3 and the perforated plates 4 on this side, and the bottom of the return air channel is connected to the evaporator chamber 102.

[0049] The baffle plate 2, air guide plate 3 and perforated plate 4 installed on the return air side of the evaporator chamber 102 can be configured with the relevant features of the baffle plate 2, air guide plate 3 and perforated plate 4 as described in Example 2.

[0050] The perforated plate 4 installed on the return air side of the evaporator chamber 102 is conducive to the uniform convergence of cold air. The air guide plate 3 can effectively guide the cold air into the evaporator 7 and prevent the cold air from blowing directly onto the baffle plate 2, thus preventing condensation. In addition, it can ensure the consistency of the structure of the vertical transparent display ends on both sides, ensuring aesthetics.

[0051] Example 4 The main difference between this embodiment and embodiment 1 is that the cabinet also includes a defogging mechanism for defogging the outer side of the baffle plate 2. The defogging mechanism includes a defogging duct 104 located on one side of the cabinet. The inlet end of the defogging duct 104 is connected to the compressor chamber 103 through the defogging fan 11, and the outlet end of the defogging duct 104 is located on the outer side of the baffle plate 2 outside the air inlet channel.

[0052] like Figure 1 , Figure 2As shown, the arrows in the defogging duct 104 indicate the direction of hot air flow.

[0053] The defogging duct 104 can be installed inside the base frame 8, or it can be installed on the outer wall of the cabinet via a duct, for example... Figure 1 As shown, the defogging duct 104 is located inside the foamed side plate of the base frame 8.

[0054] The demisting fan 11 can be a suction fan with a triangular shell, which is installed on the inner top side of the compressor chamber 103. Hot air is drawn and gathered on one side of the triangular shell to the side opposite that side, and the inlet port of the demisting duct 104 is located on that side.

[0055] The condenser 9 can be installed on the side near the cabinet and the air intake channel to ensure the temperature of the hot air.

[0056] The hot air generated by the condenser 9 and compressor 10 in the compressor chamber 103 is blown to the outer side of the baffle plate 2. On the one hand, it can dissipate heat from the compressor chamber 103, and on the other hand, it can effectively use the hot air to maintain the temperature of the baffle plate 2 to prevent condensation.

[0057] Based on embodiment 3, a defogging mechanism can also be installed on the outside of the wind deflector 2 outside the return air duct.

[0058] In addition, the defogging mechanism can use an electric heating wire installed in the wind deflector 2.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
