Description

Technical Field

[0001] This utility model relates to the field of automatic vending machine technology, and in particular to the temperature control structure of a bottled water vending machine. Background Technology

[0002] Traditional bottled water vending machines use metal plates or similar materials to divide the interior into several compartments with thin, single-layer panels. These compartments hold water bottles (i.e., bottled water containers). In low-temperature environments like winter, the water in these bottles may freeze and burst. Conversely, in high-temperature environments like summer, the increased temperature within the compartments causes the water in the bottles to overheat, making it unsuitable for use in such conditions. Utility Model Content

[0003] One objective of this invention is to solve or alleviate the aforementioned technical problems.

[0004] The present invention employs a temperature control structure for a bottled water vending machine, comprising an internal circulation component and a cabinet with multiple rows of receiving cavities. The cabinet has an electrically controlled cavity containing an electrically controlled device. The cabinet includes movable doors covering each receiving cavity, each door fixedly fitted with a locking clamp. The cabinet is also equipped with electrically controlled locks corresponding to the locking clamps and electrically connected to the electrically controlled device, locking the clamps. Each receiving cavity holds a container of water, and a circulating bottom air duct is located at the bottom of the cabinet. A circulating air duct is located between adjacent rows of receiving cavities. The cabinet has a side air duct with side air inlets on the side wall of the cavity and a rear air duct for circulation. The bottom air duct for circulation is connected to the bottom of the side air duct for circulation, and the top of the side air duct for circulation is connected to the rear air duct for circulation. The internal circulation component includes a circulation exhaust device, a heating element, and an internal circulation carrier with a circulation air inlet and a circulation air outlet. The circulation exhaust device and the heating element are fixed inside the internal circulation carrier. The internal circulation carrier is fixedly connected to the cabinet so that the circulation air inlet faces the outlet of the rear air duct for circulation and the circulation air outlet faces the inlet of the bottom air duct for circulation.

[0005] The effect achieved by this invention is to prevent or slow down the freezing of water in the container used to hold water within the containment cavity.

[0006] A further technical solution is that the cabinet is made of sheet metal, and the top of the cabinet is provided with a top exhaust chamber. The top exhaust chamber is provided with an exhaust inlet that connects to the top of the circulating side air duct, and the top exhaust chamber is provided with an exhaust device that connects to the outside.

[0007] This technical solution ensures that the temperature of the containment cavity is low when cooling is required, and it is cost-effective as it does not require additional cooling ventilation ducts.

[0008] A further technical solution is that the exhaust device is an axial flow fan that drives air through the blades by the rotation of a motor and blades, and the exhaust device is located on the rear side wall of the top exhaust chamber.

[0009] A further technical solution is that the exhaust device can be equipped with a louver structure. When the exhaust device is running, the air pushes the louver structure to achieve airflow. When the exhaust device stops running, the louver structure closes due to its own weight, so that the exhaust device is basically isolated from the outside world.

[0010] This technical solution can reduce the heat loss from the internal circulation component to the outside when insulation is required, thus saving energy.

[0011] A further technical solution is that the circulating exhaust device is fixed to the inner wall of the circulating air inlet of the inner circulating carrier, and the heating element is fixed to the inner wall of the circulating air outlet with a gap between them.

[0012] A further technical solution involves fixing the internal circulation carrier with the circulation air inlet sidewall tilted upwards.

[0013] This technical solution can slow down the airflow rate entering the internal circulation carrier, ensuring that the air is fully heated within the internal circulation carrier.

[0014] A further technical solution involves setting the side wall of the internal circulation carrier, where the heating element is fixed, to be inclined downwards, so that the circulation air outlet is directly opposite the inlet of the circulation bottom air duct.

[0015] A further technical solution involves fixing a top mounting plate and a bottom mounting plate at the top and bottom of the internal circulation carrier, respectively. The top mounting plate is fixedly connected to the rear outer wall of the cabinet, and the bottom mounting plate is connected to the rear wall of the cabinet.

[0016] This technical solution facilitates the overall disassembly and installation of the internal circulation component, thus simplifying maintenance.

[0017] A further technical solution involves the bottom mounting plate abutting against the inner rear wall of the cabinet.

[0018] This technical solution further facilitates the overall disassembly and installation of the internal circulation component, thus simplifying maintenance. Attached Figure Description

Detailed Implementation

[0028] The specific embodiments of this utility model will now be described with reference to the accompanying drawings.

[0029] As a specific embodiment, the temperature control structure of the bottled water vending machine of this utility model includes an internal circulation component 2 and a cabinet 1 with multiple rows of receiving cavities 11. It should be noted that the receiving cavities 11 at the same height constitute a row of receiving cavities 11, and the receiving cavities 11 at the same horizontal position constitute a row of receiving cavities 11.

[0030] Cabinet 1 is provided with an electrical control cavity 81, and an electrical control device is installed inside the electrical control cavity 81. It is easy to understand that the electrical control device is existing technology, such as a PLC controller, industrial computer, circuit board, or other device used to implement electrical control. Typically, cabinet 1 includes a movable functional door 819, which is provided with a screen for displaying the status of the electrically controlled lock 82 (described later) and / or for operating the electrically controlled lock 82 (described later) (not shown in the attached figures); the functional door 819 can be used to cover the electrical control cavity 81. In the embodiment where the electrical control cavity 81 is the top exhaust cavity 14 (described later), the functional door 819 can also be used to cover the receiving cavity 11 (i.e., Figure 6 The marked electrical control chamber 81 is modified to accommodate bottled water, becoming accommodating chamber 11.

[0031] The cabinet 1 includes movable cabinet doors 119 that cover each receiving cavity 11. For example, the cabinet doors 119 are hinged to one end side wall of the receiving cavity 11 and can rotate.

[0032] Each cabinet door 119 is fixedly equipped with a locking clamp 829, and each cabinet body 1 is equipped with an electrically controlled lock 82 corresponding to the locking clamp 829 and electrically connected to the electrical control device. The locking clamp 829 is locked by the electrically controlled lock 82. The electrically controlled lock 82 is existing technology, and it can be an electromagnetic lock such as the BS-0854S-105 intelligent cabinet electromagnetic lock from Dongguan Bosun Industrial Co., Ltd., or an electrically controlled lock that controls the opening and closing of the door via a motor.

[0033] The receiving cavity 11 is used to hold a container filled with water, such as bottled water. It is easy to understand that, under the function of the above structure, after the user sends a signal to the electronic control device via the screen (such as a touchscreen) or other means (e.g., after paying for the purchase, sending a wireless signal to the device via the internet), the electronic control device controls the electronic lock 82 to open and release the locking clamp 829, allowing the cabinet door 119 to be opened by the user. After opening the cabinet door 119, the user removes the container filled with water from the receiving cavity 11 and closes the cabinet door 119, thus completing the purchase.

[0034] A circulating bottom air duct 12 is provided at the bottom of the cabinet 1, a circulating side air duct 13 is provided between two adjacent rows of receiving cavities 11, a side air inlet 111 is provided on the side wall of the receiving cavity 11, and a circulating rear air duct 15 is provided at the rear of the cabinet 1. For example, Figure 6 As shown, the cabinet 1 includes five rows (two rows of accommodating cavities 11 corresponding to the function door 819) and three columns of accommodating cavities 11. The outermost column of accommodating cavities 11 has a side air inlet hole 111 on its inner side wall. The accommodating cavities 11 in the middle (other than the outermost column of accommodating cavities 11) have side air inlets 111 on both sides of their side walls.

[0035] The bottom of the circulating bottom air duct 12 is connected to the bottom of the circulating side air duct 13, for example, through the bottom inlet 131 of the side air duct. The upper part of the circulating side air duct 13 is connected to the circulating rear air duct 15, for example, through... Figure 7 As shown, it is connected through the upper inlet 151 of the rear air duct. The upper inlet 151 of the rear air duct is formed by the rear air duct plate 159 within the cabinet 1, and the upper inlet 151 of the rear air duct is opened on the rear air duct plate 159.

[0036] The internal circulation component 2 includes a circulating exhaust device 21, a heating element 22, and an internal circulation carrier 29 with a circulating air inlet 291 and a circulating air outlet 292; the circulating exhaust device 21 and the heating element 22 are respectively fixed inside the internal circulation carrier 29. The heating element 22 is existing technology, such as a conventional ceramic heating element. The circulating exhaust device 21 is existing technology; for example, the circulating exhaust device 21 and the exhaust device 3 described later are axial flow fans that drive air through the blades by the rotation of a motor and blades.

[0037] The internal circulation carrier 29 is fixedly connected to the cabinet 1, so that the circulation air inlet 291 is directly opposite the outlet of the circulation rear air duct 15 (not shown in the attached figure); and the circulation air outlet 292 is directly opposite the inlet of the circulation bottom air duct 12 (not shown in the attached figure).

[0038] The working principle is as follows: when it is necessary to keep the container containing water in the containment cavity 11 warm, such as in winter, both the circulating exhaust device 21 and the heating element 22 are turned on. The air near the heating element 22 is heated and pushed by the circulating exhaust device 21, so that the heated air (i.e., hot air) enters the bottom circulating air duct 12, then flows to the side of the bottom circulating air duct 12 and enters the side circulating air duct 13 and flows upward. Then it enters the rear circulating air duct 15 from the upper inlet 151 and then enters the circulating air inlet 291, thus completing one internal circulation process of hot air. It should be noted that the above-mentioned internal circulation process of hot air in this embodiment is a forward circulation process from the upper inlet 151 of the rear air duct to the rear circulating air duct 15 and then to the circulating air inlet 291. However, this process can also be a reverse circulation process from the circulating air inlet 291 to the rear circulating air duct 15 and then to the upper inlet 151 of the rear air duct. During the process of hot air flowing through the circulating side air duct 13, the hot air enters the receiving cavity 11 through the side air inlet 111, which raises the temperature of the air in the receiving cavity 11, thereby preventing or slowing down the freezing of water in the container used to hold water in the receiving cavity 11. It should be noted that the outermost row of receiving cavities 11 has side air inlets 111 on its inner side wall, while the middle row of receiving cavities 11 (excluding the outermost row of receiving cavities 11) has side air inlets 111 on both side walls. This structure ensures that the air in each receiving cavity 11 has only the side air inlets 111 as inlets and no air outlets are provided. This is because the temperature control structure of the bottled water vending machine in this embodiment of the present invention is designed to avoid or slow down the freezing of the containers containing water in the receiving cavities 11. It does not require a rapid heating process, but only a stable heating process. The stable heating process of the air in the receiving cavities 11 is achieved by relying on the slow diffusion of hot air itself through only the side air inlets 111 as inlets.

[0039] As one specific implementation method, the cabinet 1 is made of sheet metal. A top exhaust chamber 14 is provided at the top of the cabinet 1. The top exhaust chamber 14 has an exhaust inlet 141 that communicates with the top of the circulating side air duct 13. The top exhaust chamber 14 is equipped with an exhaust device 3 that communicates with the outside. As mentioned earlier, the exhaust device 3 is an axial flow fan or similar device that drives air through the blades via a motor and blade rotation. The exhaust device 3 is located on the rear side wall of the top exhaust chamber 14. When cooling is needed in summer or winter for containers containing water within the receiving cavity 11, the circulating exhaust device 21 and heating element 22 are stopped, and the exhaust device 3 is activated. This allows the warmer air from the receiving cavity 11, the circulating bottom air duct 12, the circulating side air duct 13, and the circulating rear air duct 15 to enter the top exhaust chamber 14 through the exhaust inlet 141 and be extracted to the outside by the exhaust device 3. In situations such as winter when it is necessary to keep the container filled with water in the housing 11 warm, the circulating exhaust device 21 and the heating element 22 are both turned on, and the exhaust device 3 is turned off (the exhaust device 3 may be equipped with a louvered structure (not shown in the attached figure). When the exhaust device 3 is running, the air pushes the louvered structure to achieve airflow. When the exhaust device 3 is not running, the louvered structure closes due to its own weight, making the exhaust device 3 largely isolated from the outside world. This can reduce the heat loss from the internal circulation component 2 to the outside world when insulation is required, which is more energy-efficient). It should be noted that the top exhaust cavity 14 can also be used to house the electrical control device, that is, the top exhaust cavity 14 is the electrical control cavity 81. The exhaust device 3 can also reduce the temperature inside the top exhaust cavity 14 (i.e., the electrical control cavity 81), which is beneficial to the stable operation of the electrical control device. It should also be noted that the cabinet 1 is made of sheet metal, which has tiny gaps between the sheet metal parts and is not completely sealed internally. Therefore, it is possible for outside air to enter the cabinet 1, thereby ensuring that the temperature of the receiving cavity 11 is low when cooling is required, and there is no need to set up additional cooling ventilation ducts, thus reducing costs.

[0040] As one of the specific implementation methods, such as Figure 3 As shown, the circulating exhaust device 21 is fixed to the inner wall of the circulating air inlet 291 of the inner circulating carrier 29, and the heating element 22 is fixed to the inner wall of the circulating air outlet 292 and a gap is provided between it and the inner wall of the inner circulating carrier 29.

[0041] As one specific implementation method, the inner circulation carrier 29 is fixed with the side wall of the circulation air inlet 291 inclined upward. The air entering the inner circulation carrier 29 from the circulation air inlet 291 is guided by the vertical inner wall of the inner circulation carrier 29 (not shown in the figure) and flows vertically downward. Compared with the vertical orientation of the circulation air inlet 291 (i.e., the inner circulation carrier 29 is a cuboid as a whole), it can slow down the air flow rate entering the inner circulation carrier 29 and ensure that the air is fully heated in the inner circulation carrier 29.

[0042] As one specific implementation method, the side wall of the inner circulation carrier 29 on which the heating element 22 is fixed is inclined downward, so that the circulation air outlet 292 is directly opposite the inlet of the circulation bottom air duct 12.

[0043] As one specific implementation method, a top mounting plate 293 and a bottom mounting plate 294 are fixedly installed at the top and bottom of the internal circulation carrier 29, respectively. The top mounting plate 293 is fixedly connected to the rear outer wall of the cabinet 1, and the bottom mounting plate 294 is connected to the rear outer wall of the cabinet 1. For example, the top mounting plate 293 and the bottom mounting plate 294 are fixed to the rear outer wall by screws. During maintenance or repair, the internal circulation component 2 can be completely disassembled by unscrewing the screws of the top mounting plate 293 and the bottom mounting plate 294 on the rear side of the cabinet 1, which facilitates the overall disassembly and installation of the internal circulation component 2 and makes maintenance easier.

[0044] As one specific implementation, the bottom mounting plate 294 abuts against the rear inner wall of the cabinet 1 (the attachment in this embodiment is not shown). During maintenance or repair, the screws of the top mounting plate 293 are unscrewed on the rear side of the cabinet 1, and then the inner circulation component 2 is moved backward and upward to allow the bottom mounting plate 294 to be pulled out from the rear inner wall of the cabinet 1, so that the inner circulation component 2 can be completely disassembled; conversely, the inner circulation component 2 can be completely installed on the cabinet 1 without rotating the screws of the bottom mounting plate 294, further facilitating the complete disassembly and installation of the inner circulation component 2 and making maintenance easier.

[0045] The terms used in this invention, such as "first," "second," etc., do not indicate any order, quantity, or importance, but are merely for distinction.

[0046] In this invention, terms such as "a" or "an" are used to indicate not a limitation on the quantity, but rather to indicate the existence of at least one of the mentioned objects.

[0047] In this utility model, terms indicating direction or location such as top, bottom, side, longitudinal, transverse, middle, center, outside, inside, horizontal, vertical, left, right, above, and below are used to indicate relative positions rather than absolute positions.

[0048] Terms used in this invention, such as "approximately," "generally," "approximately," and "similar," are limiting terms used to indicate features that are present but allow for certain deviations. The amount of deviation allowed may vary depending on the specific context; for example, regarding dimensional deviations, the specific context may include, but is not limited to, relevant standards for dimensional tolerances.
