Description

Technical Field

[0001] This utility model relates to the field of food storage cabinet technology, and more specifically to a structure for adjusting the angle of the air outlet of a food storage cabinet. Background Technology

[0002] As is generally known, refrigerated display cases are a general term for commercial refrigeration equipment, including air curtain cases, refrigerated display cases, and upright refrigerated cases. Among them, air curtain cases are open designs, using air curtains formed by upper and lower air vents and air outlets in each shelf to display and refrigerate fruits, vegetables, yogurt, and beverages.

[0003] The specific steps for operating an air curtain cabinet include pre-start preparation, setting the temperature on the control panel, placing food ingredients, and routine maintenance. When placing food ingredients, avoid blocking the mesh air outlets on each shelf. After the equipment is started, the cold air from the mesh air outlets blows directly onto the food ingredients placed on the shelves to refrigerate and preserve them. Clean the air outlets and shelves weekly, and defrost them promptly.

[0004] When the aforementioned air curtain cabinet is used for daily preservation, the air vents on each layer are usually designed to blow air horizontally. The angle of the air vents cannot be adjusted according to the type of food. If the food is not placed high enough, the cold air cannot blow directly onto the surface of the food, resulting in insufficient cooling of the food. Especially in summer, when the surface temperature of the food is high, insufficient cooling will further reduce the preservation effect of the food. Utility Model Content

[0005] In view of the above-mentioned problems in the prior art, one objective of this utility model is to provide a structure for adjusting the air outlet angle of a food storage cabinet to solve the above-mentioned shortcomings of the prior art.

[0006] To achieve the above objectives, this utility model provides a refrigerated display case air outlet angle adjustment structure, including an air curtain cabinet body and multiple shelf sections, and further including: an air guide frame, which is disposed on the shelf space formed between the air curtain cabinet body and each of the shelf sections; each of the air guide frames has an air guide channel corresponding to multiple air outlets; a positioning frame, which is disposed on each of the air guide frames, each of the air guide frames has an air guide plate hinged to it, and each air guide plate has a sliding block; the positioning frame has multiple positioning holes in its circumferential direction that engage with each of the sliding blocks.

[0007] Preferably, each of the layers has guide grooves that are opposite each other in the space, and each guide groove has a rectangular structure.

[0008] Preferably, each of the air guide frames and each of the guide grooves are in sliding fit.

[0009] Preferably, each of the guide grooves is provided with a locking hole, and each locking hole is specifically a circular hole structure.

[0010] Preferably, each of the air guide frames is provided with a protrusion that engages with each of the locking holes.

[0011] Preferably, when each of the air guide plates is in a vertical state, each of the push blocks engages with each of the positioning holes so that each of the air guide plates blocks each of the air guide channels.

[0012] Preferably, each of the air ducts is a rectangular structure, and the opening of each air duct is adapted to each of the air guide plates.

[0013] Preferably, each of the aforementioned blocks is provided with a positioning rod, and each of the aforementioned positioning rods is specifically a round rod structure.

[0014] Preferably, each of the positioning rods is adapted to each of the positioning holes.

[0015] Preferably, the air curtain cabinet body is provided with an air outlet and an air inlet.

[0016] In the above technical solution, the present invention provides a refrigerated display case air outlet angle adjustment structure, which has the following beneficial effects: When the height of the food placed on the shelf is low, the air outlet angle of the air duct is adjusted by rotating the air guide plate. The air guide plate is locked and fixed by the sliding block and the corresponding positioning hole, so that the air guide plate is in an inclined state. With the cooperation of the air guide plate and the air duct, multiple air outlets are guided, so that the cold air from the air outlets blows onto the surface of the food at a low position on the shelf. This device has multi-angle air outlet adjustment by guiding and adjusting the air outlets, which reduces or even avoids the problem that the food is not high enough and the cold air cannot blow directly onto the surface of the food, resulting in insufficient cooling of the food. Especially in summer, the surface temperature of the food is high, and insufficient cooling will further reduce the preservation effect of the food. Attached Figure Description

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] Please see Figure 1-5 An adjustable air outlet angle structure for a refrigerated display case is introduced to address the problem that, in daily use of air curtain display cases, the air outlets on each layer are usually designed to blow air horizontally, and the air outlet angle cannot be adjusted according to the type of food. If the food is not placed high enough, the cold air cannot blow directly onto the surface of the food, resulting in insufficient cooling of the food. This is especially problematic in summer when the surface temperature of the food is high, as insufficient cooling further reduces the food's preservation effect.

[0027] As a further technical solution proposed in this utility model, the system includes an air curtain cabinet body 1 and multiple shelf sections 1.3, and further includes: an air guide frame 2, which is disposed on the shelf space formed between the air curtain cabinet body 1 and each shelf section 1.3; each air guide frame 2 is provided with an air guide duct 2.1 corresponding to multiple air outlets 1.5; a positioning frame 3, which is disposed on each air guide frame 2, each air guide frame 2 is hinged with an air guide plate 4, and each air guide plate 4 is slidably provided with a lever 4.1; the positioning frame 3 is provided with multiple positioning holes 3.1 in the circumferential direction that engage with each lever 4.1. Specifically, when the height of the food placed on the shelf space is low, the air guide duct is adjusted by rotating the air guide plate 4. The air outlet angle of 2.1 is locked and fixed by the sliding block 4.1 and the corresponding positioning hole 3.1, so that the air guide plate 4 is tilted. With the cooperation of the air guide plate 4 and the air guide channel 2.1, multiple air outlets 1.5 are guided, so that the cold air from the air outlets 1.5 blows to the surface of the food at the lower position on the shelf space. This device can adjust the air outlets 1.5 by guiding them, so that they can have multi-angle air outlet adjustment. This reduces or even avoids the problem that the food is not high enough and the cold air cannot blow directly to the surface of the food, resulting in insufficient cooling of the food. Especially in summer, the surface temperature of the food is high, and insufficient cooling will further reduce the preservation effect of the food.

[0028] In this embodiment, the air outlet 1.5 is located within the shelf space. The specific number of air outlets 1.5 is set according to the needs of those skilled in the art. When the food is at a low height, the air guide plate 4 is rotated and fixed by the sliding block 4.1 engaging with the positioning hole 3.1, causing the air guide plate 4 to tilt, thereby guiding the cold air from the air outlets 1.5 towards the surface of the lower food, achieving multi-angle air outlet adjustment. The air outlet 1.5 is specifically a rectangular structure, and multiple air outlets 1.5 are located within the air guide duct 2.1, such as... Figure 3 As shown in the status; the position of the positioning hole 3.1 on the positioning frame 3 corresponds to the tilt angle of the air guide plate 4 after it is engaged with it, such as... Figure 3 As shown in the diagram, after the air guide plate 4 engages with the horizontal positioning hole 3.1, the air guide plate 4 is in a parallel state, allowing the air outlet 1.5 to directly blow cold air. When switching to other positioning holes 3.1, the tilt angle of the air guide plate 4 can be adjusted to accommodate the cold air coverage of low-lying food items, thus achieving air guide angle adjustment. The specific number and location of the positioning holes 3.1 are set according to the needs of those skilled in the art. Preferably, the number of positioning holes 3.1 is at least four, with two positioning holes 3.1 corresponding to the tilted opening of the air guide plate 4 at acute angles for low-lying food items of different heights, one positioning hole 3.1 corresponding to the parallel position of the air guide plate 4 for direct cooling when the food items are sufficiently high, and one positioning hole 3.1 corresponding to the vertical position of the air guide plate 4 for sealing and protection of the air outlet 1.5 when the machine is idle.

[0029] In another embodiment of this utility model, guide grooves 1.4 are provided opposite to each other in the space of each layer plate. Each guide groove 1.4 is generally rectangular in structure. Each air guide frame 2 is slidably engaged with each guide groove 1.4. Each guide groove 1.4 is provided with a locking hole 1.6, which is specifically a circular hole structure. Each air guide frame 2 is provided with a protrusion 2.2 that engages with each locking hole 1.6. Further, as... Figure 2 As shown in the diagram, the guide groove 1.4 provides a sliding track for the air guide frame 2. The two slide together, allowing the air guide frame 2 to move within the shelf space. The locking hole 1.6 on the guide groove 1.4, with its circular hole structure, engages with the protrusion 2.2 to lock and fix the position of the air guide frame 2. After the engagement, the air duct 2.1 corresponds to multiple air outlets 1.5, as shown... Figures 4-3 The status is as shown.

[0030] When the air curtain cabinet body 1 is idle, in order to prevent dust from entering the multiple air outlets 1.5, in another embodiment of this utility model, when each air guide plate 4 is in a vertical state, each lever 4.1 engages with each positioning hole 3.1, so that each air guide plate 4 blocks each air duct 2.1, such as... Figure 2As shown in the diagram, after the air guide plate 4 rotates to a vertical position, it blocks and seals the air guide duct 2.1, thereby preventing dust from entering the multiple air outlets 1.5. After the air guide plate 4 rotates, it is fixed by engaging with the corresponding positioning hole 3.1 on the positioning frame 3 through the sliding block 4.1.

[0031] In another embodiment of this utility model, each air guide duct 2.1 is specifically a rectangular structure, and the opening of each air guide duct 2.1 is adapted to each air guide plate 4. Further, as shown... Figure 3 As shown in the diagram, the air guide plate 4 and the opening of the air guide duct 2.1 are compatible. When the air guide plate 4 is in a vertical position, the rectangular structure of the air guide plate 4 can be compatible with the rectangular structure of the air guide duct 2.1. When the two are combined, the air guide plate 4 blocks the air guide duct 2.1. The compatible opening design allows the air guide plate 4 to always form a good fit with the air guide duct 2.1 when the angle is adjusted. No matter whether the air guide plate 4 is in an acute angle, parallel or vertical position, it can accurately guide the flow of cold air and prevent the cold air from being dispersed and lost in the gap between the air guide duct 2.1 and the air guide plate 4, thus ensuring the cooling effect after the angle is adjusted.

[0032] In another embodiment of this utility model, each lever 4.1 is provided with a positioning rod 4.2, each positioning rod 4.2 is specifically a round rod structure, and each positioning rod 4.2 is adapted to each positioning hole 3.1, such as... Figure 5 As shown in the figure, the surface of the positioning rod 4.2 with the round rod structure is smooth, and the friction is small when it is engaged with the positioning hole 3.1 (round hole). When rotating the air guide plate 4 to switch the positioning hole 3.1, the insertion, removal and locking process is smoother and the operation is convenient.

[0033] In another embodiment of this utility model, the air curtain cabinet body 1 is provided with an air outlet 1.1 and an air inlet 1.2. Furthermore, the air outlet 1.1 and the air inlet 1.2 form an air curtain, and the air outlets 1.5 in each shelf provide airflow to keep the placed food fresh. Figure 1 As shown in the diagram, the air outlet 1.1 is used to output cooled air, while the air inlet 1.2 is used to recycle air from inside the cabinet. At the same time, the air outlet 1.5 in each shelf space outputs air independently, directly covering the food on the shelf. That is, through the layout of the air curtain and the layered air outlets 1.5, hot air is isolated to keep the food fresh. This is existing technology and will not be described in detail.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
