Description

Technical Field

[0001] The invention belongs to the field of refrigerated display cabinets, and in particular relates to an energy-saving and environment-friendly variable frequency refrigerated display cabinet. Background Art

[0002] With the development of society and the improvement of people's quality of life, people's consumption of various desserts has increased. Dessert shops and bakery shops are spread all over cities. In dessert shops, merchants need to show customers exquisite and beautiful products to attract customers to buy, and the displayed goods need to be refrigerated to prevent the goods from spoiling too quickly. Therefore, refrigerated display cabinets have appeared on the market.

[0003] Refrigerated display cabinets generally have a large transparent area to facilitate the display of goods to customers, and need to be equipped with doors for customers or merchants to take and put goods. These factors determine the structure and function of refrigerated display cabinets, such as:

[0004] The Chinese patent with the authorization announcement number CN214179890U discloses a cake cabinet with a front door, including an equipment box; a cabinet body is fixedly installed on the upper surface of the equipment box; frames are fixedly installed on the left and right side walls of the cabinet body, and transparent glass is embedded in the middle of the frames; front guide rails are fixedly installed horizontally on the upper and lower end surfaces of the front side of the cabinet body, and rear guide rails are fixedly installed horizontally on the upper and lower end surfaces of the rear side of the cabinet body. Slide grooves are formed on the front guide rails and the rear guide rails, and a front transparent cabinet door is installed inside the slide grooves arranged on the front guide rails, and a transparent cabinet door is installed on the rear guide rails. A rear transparent cabinet door is installed inside the slide slot, and handles are fixedly installed on the outer middle parts of the front transparent cabinet door and the rear transparent cabinet door. An air inlet net and an air outlet net are embedded in the rear wall of the equipment box. Two cooling fans are symmetrically arranged on the condenser to blow air to cool the condenser. A baffle is arranged on the support frame to reduce the reflux of cold air generated by the evaporator into the interior of the equipment box, thereby reducing the problem of insufficient cold air circulation inside the cabinet. Multiple cold fans are arranged at intervals on the inclined surface of the evaporator to make the cold air circulation inside the cabinet more uniform, thereby improving the cooling effect.

[0005] However, the existing refrigerated display cabinets still have the following problems in actual use:

[0006] 1. The existing refrigerated display cabinets use ordinary double-track sliding cabinet doors in the product display area. There will inevitably be a gap between the two cabinet doors. The gap between the cabinet doors will cause cold air leakage and affect the refrigeration effect. Even if the existing refrigerated display cabinets are provided with sealing strips between the gaps of the two cabinet doors, after long-term use, the sealing strips will repeatedly rub against the surface of the glass cabinet door, which is easy to leave marks on the surface of the glass cabinet door that are difficult to clean.

[0007] 2. The glass surface of the upper display cabinet needs to be cleaned daily to ensure hygiene and aesthetics. In order to improve the sealing effect, there needs to be an overlapping area between the glass doors. However, the overlapping area is difficult to clean effectively, resulting in sanitary dead corners and affecting the appearance.

[0008] 3. When the existing refrigerated display cabinet is in use, it is impossible to change the frequency according to the number of goods in the display cabinet, and it can only operate continuously at the rated power. It is difficult to effectively cool when there are more goods, and it wastes energy when there are fewer goods.

[0009] 4. Due to the internal refrigeration of the display cabinet, there is a temperature difference between the inside and outside of the glass. However, general refrigerated display cabinets use single-layer glass, which can easily cause fog on the glass surface, reducing the display effect of the goods and affecting the customers' desire to buy.

[0010] 5. After customers or merchants take or put goods, they sometimes forget to close the cabinet door, or do not close the cabinet door completely. However, the existing refrigerated display cabinets cannot close the door automatically, causing unnecessary leakage of cold air, thereby reducing the refrigeration effect and increasing energy consumption. Summary of the invention

[0011] In order to overcome the deficiencies of the prior art, the present invention solves the technical problem of automatically converting the frequency through a variable frequency power supply component, increasing the power to ensure the refrigeration effect when the number of commodities is large, and reducing the power when the number of commodities is small, thereby achieving the effect of frequency reduction, energy saving and environmental protection. The two glass cabinet doors are in the same plane when closed, so the surfaces of the glass cabinet doors can be fully cleaned without cleaning dead corners, thereby improving the hygiene and appearance of the refrigerated display cabinet, and effectively achieving a good sealing effect, avoiding the leakage of cold air and wasting energy, and due to the sliding effect of the two glass cabinet doors, the elastic rubber strips do not rub against the surfaces of the glass cabinet doors when the glass cabinet doors slide open, thereby avoiding The elastic rubber strip is prevented from forming scratches on the surface of the glass door after long-term use, ensuring the aesthetic effect. When the guest forgets to close the door or does not close the glass door tightly, the door closing motor and the synchronous belt are used to realize the automatic door closing function, avoiding unnecessary energy waste caused by excessive leakage of cold air. The through holes of the blowing grille plate are set tilted and the wind shield is used to block the cold air, so as to avoid the cold air directly acting on the glass door and reduce the fogging on the surface of the glass door.

DETAILED DESCRIPTION

[0043] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0044] Embodiment 1:

[0045] like Figure 1-11 As shown, an energy-saving and environmentally friendly variable frequency refrigerated display cabinet includes a cabinet 10, a heat-insulating foam layer is arranged in the wall of the cabinet 10, a bottom plate 26 is fixedly connected to the bottom of the cabinet 10, a variable frequency power supply component 27 is fixedly connected to the bottom plate 26, four storage brackets 17 are symmetrically distributed and fixedly connected at the four corners of the bottom side of the cabinet 10, each storage bracket 17 is fixedly connected to the top of a pressure sensor 18, and a first storage plate 14 is supported on the top of the four pressure sensors 18, and a first storage plate 14 is fixedly connected to the side of the first storage plate 14 close to the vertical part of the cabinet 10. A return air grille plate 15 is provided, and a second storage plate 53 is clamped on the return air grille plate 15. A blow air grille plate 16 is fixedly connected to the side of the first storage plate 14 away from the return air grille plate 15. A plurality of groups of through slots are evenly distributed on the return air grille plate 15, and a plurality of through holes are evenly distributed on the blow air grille plate 16. A refrigerator 20 is fixedly connected to the cabinet body 10 below the first storage plate 14, and a plurality of first fans 19 are evenly distributed and fixedly connected to one side of the air guide cover 22, and an air outlet of each first fan 19 is connected to the air guide cover 22.

[0046] By setting up the first fan 19 and the refrigerator 20, the air in the cabinet 10 can be circulated and cooled to form a cold air flow, and the goods in the cabinet 10 can be displayed and refrigerated. By setting up the pressure sensor 18, the number of goods in the cabinet 10 can be automatically detected, and then the frequency can be automatically changed through the variable frequency power supply component 27. When the number of goods is large, the power is increased to ensure the refrigeration effect, and when the number of goods is small, the power is reduced to achieve the effect of frequency reduction, energy saving and environmental protection.

[0047] like Figure 1-11 As shown, a plurality of casters 28 are rotatably connected to the bottom of the base plate 26 , and a foot support 29 is threadedly connected to the bottom of the base plate 26 near each caster 28 .

[0048] By providing the casters 28, the refrigerated display cabinet can be conveniently moved, and by providing the foot supports 29, the refrigerated display cabinet can be stably fixed at a designated position, which is convenient for use.

[0049] like Figure 1-11 As shown, two side glass plates 11 are fixedly connected at both ends of the cabinet body 10, and two glass cabinet doors 12 are slidably arranged between the two side glass plates 11. Two slide rail plates 30 are fixedly connected at both ends of the glass cabinet doors 12 in the cabinet body 10, and the two slide rail plates 30 are parallel to each other and inclined relative to the ground. A first slide rail 31 and a second slide rail 32 that are connected to each other are respectively opened on one side of each slide rail plate 30 close to the glass cabinet door 12, and the first slide rail 31 is ensured to be below the second slide rail 32. A glass bracket 34 is fixedly connected at both ends of each glass cabinet door 12, and each glass bracket 34 is rotated on A group of pulleys 33 are connected, and each group of pulleys 33 can slide in the first slide rail 31 and the second slide rail 32. A first paddle 36 is rotatably connected to the middle of each slide rail plate 30, and a group of mutually symmetrical second paddles 37 are rotatably connected to both ends of each slide rail plate 30. A connecting rod 38 is hinged between each first paddle 36 and a corresponding group of second paddles 37. A plurality of grooves 50 are evenly distributed on the outside of each first paddle 36 and the second paddle 37. A spring 49 that can be engaged with the groove 50 is fixedly connected to the position where each slide rail plate 30 is opened into the first paddle 36 and the second paddle 37.

[0050] The two glass doors 12 are in the same plane when closed, so the surfaces of the glass doors 12 can be fully cleaned without any blind spots, thereby improving the hygiene and aesthetics of the refrigerated display cabinet, and effectively achieving a good sealing effect to avoid air conditioning leakage and energy waste. When the glass doors 12 are opened, the glass doors 12 change their trajectory so that the two glass doors 12 can be opened by sliding in an offset manner. By setting the first paddle 36 and the second paddle 37, the order in which the two glass doors 12 are opened is not restricted, and after one glass door 12 is opened, the other glass door 12 can still slide open normally, which will not cause a burden to the guests.

[0051] like Figure 1-11As shown, transparent elastic strips 52 are fixedly connected on both sides of each glass cabinet door 12, the two elastic strips 52 between the two glass cabinet doors 12 can be squeezed and sealed with each other, the elastic strips 52 of the two glass cabinet doors 12 close to the side glass plate 11 can be squeezed and sealed with the side glass plate 11, and handles 13 are fixedly connected to one side of the surface of the two glass cabinet doors 12 close to the adjacent side glass plate 11, and a support plate 25 is fixedly connected near each slide rail plate 30 in the cabinet body 10, and the end of each support plate 25 can be abutted and sealed with the corresponding glass bracket 34.

[0052] By providing the elastic strip 52 and the support plate 25, a better sealing effect is provided, and the leakage of cold air is further reduced, achieving the effect of energy saving and environmental protection. In addition, due to the sliding effect of the two glass cabinet doors 12, when the glass cabinet door 12 slides open, the elastic strip 52 does not rub against the surface of the glass cabinet door 12, thereby avoiding the elastic strip 52 from forming scratches on the surface of the glass cabinet door 12 after long-term use, thereby ensuring the aesthetic effect. In addition, by providing the handle 13, it is convenient for guests to open and close the glass cabinet door 12, and the positional relationship between the two glass cabinet doors 12 can be limited after the glass cabinet door 12 is opened, thereby avoiding the position exchange of the two glass cabinet doors 12 causing the subsequent glass cabinet door 12 to be unable to open normally.

[0053] like Figure 1-11 As shown, a group of wheel frames 45 are fixedly connected at both ends of the top of each slide rail plate 30, a group of main pulleys 44 are rotatably connected in each group of wheel frames 45, and a synchronous belt 41 is transmission-connected to each group of main pulleys 44, and a door closing motor 46 is fixedly connected to the side of each slide rail plate 30 away from the glass cabinet door 12 at the corresponding position of each main pulley 44, and the power output end of each door closing motor 46 is transmission-connected to the corresponding main pulley 44, a group of secondary pulleys 43 are rotatably connected in each group of wheel frames 45, and each synchronous belt 41 bypasses the outside of the corresponding group of secondary pulleys 43, and a connecting plate 39 is fixedly connected to the glass bracket 34 near the corresponding synchronous belt 41 on each glass cabinet door 12, and each connecting plate 39 is provided with a belt groove 40 for accommodating the synchronous belt 41 to pass through, and a group of buckle plates 42 are fixedly connected to each synchronous belt 41 at both sides of the corresponding belt groove 40, and the buckle plates 42 can slide relative to the connecting plate 39.

[0054] By setting the synchronous belt 41 and the connecting piece 39, when the guest forgets to close the glass cabinet door 12 or does not close the glass cabinet door 12 tightly, the glass cabinet door 12 can be automatically pulled to the initial position to achieve the effect of automatic door closing, thereby effectively reducing unnecessary cold air leakage and achieving energy-saving and environmental protection effects.

[0055] like Figure 1-11 As shown, a magnetic block 47 fixedly connected to the glass bracket 34 is provided near each connecting piece 39 , and a Hall sensor 48 is fixedly connected to the side wall of the cabinet 10 at a position corresponding to each magnetic block 47 .

[0056] By setting up the Hall sensor 48, it is possible to detect whether the glass door 12 is closed and whether it is closed tightly, and cooperate with the frequency conversion power supply component 27 to reduce the power of the first fan 19 and the refrigerator 20 when the glass door 12 is opened, so as to avoid the first fan 19 and the refrigerator 20 doing useless work and reduce energy consumption. In addition, by setting up two groups of magnetic blocks 47 and Hall sensors 48, it is possible to detect the order in which the two glass doors 12 are opened, so that the door closing motor 46 can automatically close the two glass doors 12 in order, ensure that the two glass doors 12 are closed correctly, and ensure the stability of the operation of the device.

[0057] In this embodiment, initially, the operator moves the refrigerated display cabinet to a designated position, screws the foot support 29 to fix the refrigerated display cabinet in place, and then connects the refrigerated display cabinet to a power supply and a control system. At this time, the two glass cabinet doors 12 are closed and in the same plane.

[0058] Subsequently, the control system starts the variable frequency power supply component 27, the first fan 19 and the refrigerator 20. The first fan 19 operates to draw the air in the cabinet 10 from the slot of the return air grille 15 into the refrigerator 20. The refrigerator 20 operates to cool the air, and the cooled air is blown out from the blowing grille 16, continuously circulating to form a cold air flow, and the internal temperature of the cabinet 10 is detected by the infrared temperature sensor 24. In conjunction with the variable frequency power supply component 27, the temperature in the cabinet 10 can be controlled within a suitable range to ensure the refrigeration effect.

[0059] When in use, the merchant can open the glass cabinet door 12, place the goods that need to be displayed and refrigerated on the first storage plate 14 or the second storage plate 53, and then close the glass cabinet door 12. The customer can open the glass cabinet door 12 and take away the desired goods according to their needs. The pressure sensor 18 can detect the weight of the goods on the first storage plate 14 and the second storage plate 53, and then determine the number of goods. The power of the first fan 19 and the refrigerator 20 can be changed according to the number of goods through the variable frequency power supply component 27. When the number of goods is large, the power is increased to ensure the refrigeration effect, and when the number of goods is small, the power is reduced to achieve the effect of energy saving.

[0060] When merchants and customers are taking and putting away goods, when the glass doors 12 are in a closed state, the two glass doors 12 are in the same plane and there is no overlapping part of the two glass doors 12. Merchants can completely clean the surface of the glass doors 12 without cleaning dead corners, thereby ensuring the hygiene and beauty of the refrigerated display cabinet. The elastic strip 52 blocks the gap at the edge of the glass door 12, and the glass bracket 34 fits tightly against the support plate 25 to achieve a good sealing effect, thereby avoiding energy waste caused by cold air leakage.

[0061] When the glass door 12 is opened by the merchant or the guest, the merchant or the guest pulls the handle 13 to slide and open the glass door 12. At this time, the pulley 33 corresponding to the unopened glass door 12 presses against the first paddle 36 to prevent it from rotating, and the second paddle 37 is consistent with the first paddle 36 due to the hinge of the connecting rod 38. The pulley 33 corresponding to the opened glass door 12 can only be guided by the second paddle 37, the first paddle 36 and the guide piece 35 to overcome gravity and slide into the second slide rail 32. The opened glass door 12 slides on the second slide rail 32. At this time, the elastic strip 52 will not rub against the surface of the glass door 12, thereby avoiding scratches on the surface of the glass door 12.

[0062] When the first and second slide rails 31 are in contact with each other, the first and second slide rails 32 are in contact with each other, and the first and second slide rails 31 are in contact with each other, so that the two glass doors 12 can slide on the first and second slide rails 31 and 32 respectively without being affected by each other. When the glass door 12 needs to be closed, the glass door 12 sliding on the first slide rail 31 is first reset, and the pulley 33 hits the protruding part of the second slide rail 37 so that the second and first slide rails 37 and the first slide rail 36 are reset to be vertical again. Then, the glass door 12 sliding on the second slide rail 32 is reset. When the glass door 12 sliding on the second slide rail 32 moves to the end, it falls back into the first slide rail 31 under the action of gravity, so that the two glass doors 12 are closed on the same plane again.

[0063] Since the first paddle 36 and the second paddle 37 can be tilted in two directions respectively, the order in which the two glass cabinet doors 12 are opened is not restricted. No matter which glass cabinet door 12 the guest opens first, the glass cabinet door 12 opened first can slide into the second slide rail 32, and the glass cabinet door 12 opened later can slide in the first slide rail 31, which will not cause inconvenience to the guest's use. In addition, the handle 13 on the glass cabinet door 12 opened later can limit the movement range of the glass cabinet door 12 opened first, thereby avoiding the wrong closing of the two glass cabinet doors 12 due to the position swap of the two glass cabinet doors 12, and further avoiding the inability of the two glass cabinet doors 12 to open normally after the wrong closing of the two glass cabinet doors 12.

[0064] When the guest opens the glass door 12, the door closing motor 46 is in a stopped state. When the guest pulls the glass door 12, the connecting piece 39 moves with the glass door 12. The connecting piece 39 pulls the synchronous belt 41 through the buckle piece 42 to operate, so that the main pulley 44 and the door closing motor 46 idle, which does not affect the guest's normal opening of the glass door 12. The corresponding connecting piece 39 on the glass door 12 entering the second slide rail 32 is also lifted up, and the corresponding synchronous belt 41 slides in the belt groove 40, which does not change the shape of the synchronous belt 41.

[0065] After the glass door 12 is opened, the Hall sensor 48 detects the movement of the magnetic block 47, and a delay time is set in the control system. When the delay time is reached, the control system starts the corresponding door closing motor 46, so that the synchronous belt 41 actively operates to move the opened glass door 12 back to the initial closed state, and the opening sequence of the glass doors 12 can be detected by the separation sequence of the two groups of magnetic blocks 47 and the Hall sensor 48. The control system can correctly close the two glass doors 12 in sequence until the magnetic block 47 is close to the Hall sensor 48 again. The control system turns off the door closing motor 46. When the guest forgets to close the door or does not close the glass door 12 tightly, the automatic door closing function is realized to avoid unnecessary energy waste caused by excessive leakage of cold air.

[0066] Furthermore, when the magnetic block 47 and the Hall sensor 48 are separated, the control system automatically determines that the glass cabinet door 12 is in an open state, and controls the variable frequency power supply component 27 to reduce the power of the first fan 19 and the refrigerator 20, and restores the operating power of the first fan 19 and the refrigerator 20 when the magnetic block 47 and the Hall sensor 48 are close again, thereby avoiding energy waste caused by high-power operation of the refrigerated display cabinet when it is opened, and achieving energy-saving and environmental protection effects.

[0068] like Figure 1-11 As shown, the through hole of the blowing grille 16 is tilted to point to the second storage plate 53, a transparent wind shield 23 is fixedly connected between the blowing grille 16 and the glass cabinet door 12, an air guide cover 22 is fixedly connected to the outside of the cabinet 10, the opening of the air guide cover 22 points to the glass cabinet door 12, a plurality of second fans 21 are evenly distributed and fixedly connected to the bottom side of the cabinet 10, the air outlet of each second fan 21 is connected to the inside of the air guide cover 22, an air inlet groove 51 is opened on the side wall of the cabinet 10 at a position corresponding to the variable frequency power supply component 27, an infrared temperature sensor 24 is fixedly connected to the top support plate 25, and the infrared temperature sensor 24 is tilted.

[0069] In this embodiment, the through holes of the blowing grille 16 are set at an angle and cooperate with the wind shield 23 to block the cold air, so as to prevent the cold air from directly acting on the glass door 12 and reduce the fogging on the surface of the glass door 12. In addition, the heat generated by the operation of the variable frequency power supply component 27 is used to heat up the air around the variable frequency power supply component 27, and the hot air is blown to the outer surface of the glass door 12 through the second fan 21, so as to eliminate the fogging on the surface of the glass door 12.

[0070] During the operation of the second fan 21, the outside air of the refrigerated display cabinet is continuously sucked into the air inlet slot 51, thereby achieving a cooling effect on the variable frequency power supply component 27 and ensuring the normal and stable operation of the variable frequency power supply component 27. The infrared temperature sensor 24 can detect the temperature inside the cabinet 10 and cooperate with the variable frequency power supply component 27 to achieve variable frequency energy saving. The second fan 21 cooperates with the magnetic block 47 and the Hall sensor 48 to turn off the second fan 21 when the glass cabinet door 12 is opened, thereby avoiding unnecessary energy consumption and saving energy and protecting the environment.

[0071] The above-mentioned pressure sensor 18, first fan 19, refrigerator 20, second fan 21, infrared temperature sensor 24, variable frequency power supply component 27, door closing motor 46, Hall sensor 48, etc. are mature existing technologies and are only shown in the drawings and will not be repeated in this article.

[0072] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.

[0073] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.

[0074] The above description shows and describes several preferred embodiments of the present application, but as mentioned above, it should be understood that the present application is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the application concept described herein through the above teachings or the technology or knowledge of the relevant field.
