Description

Technical Field

[0001] This utility model relates to the field of water cup technology, specifically to an energy-saving thermos cup that can be used for both hot and cold water. Background Technology

[0002] With social development, people are becoming increasingly aware of health and wellness, one aspect of which is ensuring sufficient daily water intake. Therefore, insulated water bottles, as a type of water container, have gradually developed different functions. Insulated water bottles are primarily used to maintain the temperature of hot water inside. However, due to their excellent heat retention, hot water often doesn't cool down quickly after being poured in. Opening the lid to cool the water can lead to impurities falling in, and it's also easy to overdo it and let the water cool for too long, exceeding the optimal drinking temperature.

[0003] Therefore, in order to accelerate the cooling of hot water, some insulated cups that can cool have appeared on the market. For example, the existing patent with publication number CN215383033U discloses a hot and cold cup, which includes an insulated cup body, a semiconductor cooling chip and a thermally conductive support body. The insulated cup body is provided with a receiving cavity. One side of the semiconductor cooling chip is connected to the insulated cup body, one end of the thermally conductive support body is connected to the other side of the semiconductor cooling chip, and the other end of the thermally conductive support body is used to support the insulated cup body. The insulated cup body has a heat preservation effect and can maintain the temperature inside the receiving cavity, so that the heated or cooled beverage is not easy to cool down or heat up again.

[0004] Existing patent CN221830387U discloses a detachable water cup that combines phase change rapid cooling and heat preservation. It includes a detachable cup body, an inner liner, and a lid. A sealed cavity exists between the outer and inner walls of the cup body. An inner liner cavity exists between the inner and outer walls of the inner liner, filled with a phase change material layer for rapid cooling. A foam metal layer is also attached to the inner wall of the inner liner, and multiple sets of annular ribs are arranged on the outer side of the foam metal layer, spaced apart along the height of the cup body. This water cup, with its inner liner filled with a phase change material layer for rapid cooling, and the detachable inner liner, allows for rapid cooling of boiling water to the phase change temperature of the phase change material and maintains a constant temperature when the inner liner is in place. When the inner liner is removed, it allows for long-term heat preservation of hot water, thus achieving integrated rapid cooling and heat preservation.

[0005] Both of the above-mentioned existing technologies achieve cooling of hot water in the thermos. In the first prior art, one end of the semiconductor cooling chip cools while the other end heats, but this function is not utilized in the first prior art, resulting in insufficient energy utilization. The prior art in the second prior art also achieves the effect of water temperature regulation, but this makes it difficult to adjust the water temperature in the thermos, which cannot meet the different water temperature requirements of different people and has low applicability. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies and provide an energy-saving thermos cup that can be used for both cooling and heating. It combines a semiconductor cooling chip that can achieve either cooling or heating with a phase change material, so that when the cooling end of the semiconductor cooling chip is cooling hot water, the heat generated by the heating end can be absorbed by the phase change material and used for heating. Therefore, it can achieve both cooling and heating while saving energy. Furthermore, different water temperatures can be obtained through the semiconductor cooling chip to meet the different water temperature requirements of different people.

[0007] To solve the above problems, the present invention adopts the following solution:

[0008] An energy-saving thermos cup for both hot and cold use includes an inner liner, a cup shell, and a cup holder located below the inner liner and detachably connected to the cup shell. An installation cavity is formed between the inner liner, the cup shell, and the cup holder. A semiconductor cooling chip connected to the bottom of the inner liner is installed in the installation cavity. A heat sink is provided at the lower end of the semiconductor cooling chip. The semiconductor cooling chip is connected to the same power source through two sets of circuits. When the current flows through the semiconductor cooling chip in the two sets of circuits, the current flows in opposite directions. A phase change material that can absorb and store heat can also be detachably connected to the installation cavity. The phase change material is connected to a heat-conducting component for transferring heat to the outer wall of the inner liner and separating it from the outer wall of the inner liner.

[0009] In the above scheme, the semiconductor cooling chip is connected to the bottom of the inner liner via two sets of circuits with opposite current flows. The end of the semiconductor cooling chip can be selected as either the cooling end or the heating end. Therefore, the water in the thermos can be cooled or heated to achieve water temperature regulation. When the hot water is cooled, the lower end of the semiconductor cooling chip will generate heat. The phase change material can absorb and store the heat. When the temperature of the absorbed heat exceeds the phase change point of the phase change material, if the water in the inner liner needs to be heated later, the heat stored in the phase change material can be transferred to the outer wall of the inner liner to heat the water first through the phase change material and the heat conduction component. This avoids direct reheating through the semiconductor cooling chip, improves energy utilization, and saves energy consumption.

[0010] Preferably, the phase change materials are connected in pairs and centrally symmetrically within the mounting cavity, and two sets of heat-conducting components are provided accordingly.

[0011] The above settings are designed to make the phase change material heat the inner liner faster and better.

[0012] Preferably, the heat-conducting component includes a first heat-conducting element and a second heat-conducting element. The plane at the upper end of the first heat-conducting element coincides with the plane at the lower end of the second heat-conducting element. The four side walls of the first heat-conducting element are wrapped with phase change material. The second heat-conducting element is coaxially disposed between the inner liner and the cup shell. The cup shell has a sliding channel. The second heat-conducting element is connected to a sliding handle that passes through the sliding channel and can slide along the sliding channel.

[0013] In the above configuration, when the phase change material absorbs heat and needs to transfer it to the inner liner, the sliding handle is slid along the sliding channel, thereby driving the second heat-conducting element to move so that the upper end of the first heat-conducting element coincides with the lower end of the second heat-conducting element. When heat transfer needs to be blocked, the sliding handle is slid in the opposite direction.

[0014] Preferably, a baffle plate that can block the sliding channel is connected to the side wall of the second heat-conducting component. The height position of the baffle plate corresponds to the height position of the sliding channel, and the baffle plate is located on the side close to the sliding handle.

[0015] A baffle plate is installed to block the sliding channel and prevent excessive heat from dissipating from it.

[0016] Preferably, the cup holder has heat dissipation holes that communicate with the outside.

[0017] Heat dissipation holes are provided so that when the heat generated at the heating end of the thermoelectric cooler is too high and cannot be absorbed by the phase change material, it can be dissipated to the outside through the heat dissipation holes, thus avoiding damage to the thermoelectric cooler.

[0018] Preferably, the heat dissipation holes are formed on a portion of the bottom of the cup holder and a portion of the peripheral wall of the cup holder. An adjustment sleeve is coaxially rotatably fitted onto the bottom of the cup holder, and the adjustment sleeve has adjustment holes that expose the heat dissipation holes.

[0019] The above configuration allows for adjustment of the exposed area of ​​the heat dissipation holes, thereby regulating the ambient temperature inside the mounting cavity. Therefore, when the heat generated by the semiconductor cooling chip is lower than the phase change point of the phase change material, the heat generated can be absorbed and stored by the phase change material by adjusting the mounting sleeve to block all the heat dissipation holes.

[0020] Preferably, heat insulation cotton is connected to both sides of the second heat-conducting element, and when the second heat-conducting element is separated from the first heat-conducting element, a distance is left between the two phase change materials and each heat insulation cotton in the circumferential direction.

[0021] The installation of heat insulation cotton and the maintenance of circumferential distance are all to prevent the heat generated by the phase change material from being transferred to the second heat conductor when heating through the phase change material is not required.

[0022] Preferably, the lower end surface area of ​​the second heat-conducting element is larger than the upper end surface area of ​​the first heat-conducting element.

[0023] The above configuration ensures that the upper end of the first heat-conducting element can make full contact with the second heat-conducting element, thus ensuring that the heat from the first heat-conducting element can be fully transferred.

[0024] Preferably, a first temperature sensor is installed at the upper end of the mounting cavity near the inner liner, and the cup shell is connected to a display screen that can display the detected temperature of the first temperature sensor.

[0025] The above settings are for easy monitoring of water temperature, thus facilitating its use.

[0026] Preferably, a second temperature sensor connected to the display screen is also installed in the mounting cavity between the cup holder and the bottom of the inner liner.

[0027] A second temperature sensor is installed to understand the ambient temperature between the cup holder and the bottom of the inner liner, which can then be compared with the phase change temperature of the phase change material to facilitate determining whether to open the heat dissipation vents and to what extent.

[0028] The beneficial effects of this utility model are as follows:

[0029] This invention incorporates a semiconductor cooling chip, which is connected via two sets of circuits with opposite current flows. This allows for the selection of whether one end of the semiconductor cooling chip connected to the bottom of the inner liner is a cooling end or a heating end, thus enabling the cooling or heating of the water in the thermos and achieving water temperature regulation.

[0030] This invention incorporates a phase change material and a heat-conducting component that can be separated from the outer wall of the inner liner. This allows the heat generated by the semiconductor refrigeration chip during cooling to be absorbed and stored by the phase change material instead of wasted. When it is necessary to reheat the water inside the inner liner, the heat stored in the phase change material can be transferred to the outer wall of the inner liner through the heat-conducting component to achieve heating, avoiding direct reheating through the semiconductor refrigeration chip, thus improving energy utilization and saving energy consumption.

Detailed Implementation

[0038] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the figures only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0039] In this embodiment, reference Figures 1-3 An energy-saving thermos cup that can be used for both hot and cold drinks includes an inner liner 1, a cup shell 2, a cup base 3, and a cup lid 4. The cup shell 2, the cup lid 4, and the cup base 3 are all connected by threads. An installation cavity is formed between the inner liner 1, the cup shell 2, and the cup base 3.

[0040] To facilitate the handling of the thermos in multiple ways, a connecting sleeve 104 is threaded onto the upper side of the cup shell 2, and a fixed handle is attached to the connecting sleeve 104 for easy handling and drinking. The connecting sleeve 104 is also hinged to a lifting handle 1052 for easy carrying. The outer wall of the cup shell 2 is provided with anti-slip texture 1053 to prevent slipping and make it easy to directly grip the thermos.

[0041] refer to Figure 2 To further facilitate drinking hot water and avoid the need to only unscrew the cup lid 4, an installation groove 41 is provided on the upper end of the cup lid 4. An opening and closing component 108 is rotatably hinged in the installation groove 41. The opening and closing component 108 has a drinking channel 1081 that can communicate with the inside of the inner liner 1. A food-grade straw can be inserted into the drinking channel 1081 to the bottom of the inner liner 1. Therefore, the opening and closing component 108 can be opened by rotating it, and then warm water can be drunk through the drinking channel 1081 and the straw.

[0042] refer to Figures 1-6To regulate the water temperature in the inner liner 1, a semiconductor cooling chip 51 connected to the bottom of the inner liner 1 is installed in the mounting cavity. The lower end of the semiconductor cooling chip 51 is equipped with a heat sink 52 with a fan. The semiconductor cooling chip 51 is connected to the same power source through two sets of circuits (the power source and circuits are not shown in the figure). When the current flows through the semiconductor cooling chip 51 in the two sets of circuits, the current flows in opposite directions. The two sets of circuits are also connected to two control switches 106, which are used to control cooling and heating respectively. The two control switches 106 are connected to the outer wall of the cup shell 2. A charging port 107 for charging the power source is also provided on the upper side of the cup shell 2. By using the two sets of circuits with opposite current flows, it is possible to select whether one end of the semiconductor cooling chip 51 connected to the bottom of the inner liner 1 is the cooling end or the heating end. Therefore, the water in the thermos can be cooled or heated to achieve water temperature regulation.

[0043] To ensure that the heat generated at the other end of the semiconductor cooling chip 51 is absorbed and stored when cooling hot water, thus improving energy efficiency, a phase change material 6 capable of absorbing and storing heat is detachably connected to the inner peripheral wall of the installation cavity. Since the optimal drinking water temperature for the human body is around 40°C, and the water in the inner tank 1 will cool naturally, the phase change temperature of the phase change material 6 is set higher, at 50°C. The phase change material 6 is connected to a heat-conducting component 7 for transferring heat to the outer wall of the inner tank 1 and for separating it from the outer wall of the inner tank 1. The gap between the heat-conducting component 7 and the outer wall of the inner tank 1 is extremely small to ensure that the heat from the heat-conducting component 7 is transferred to the inner tank 1.

[0044] Therefore, when the phase change material 6 absorbs and stores heat, if the water in the inner tank 1 needs to be heated later, the heat stored in the phase change material 6 can be transferred to the outer wall of the inner tank 1 through the phase change material 6 and the heat conduction component 7 to achieve heating, avoiding direct reheating through the semiconductor cooling chip 51, thus saving energy. If the water temperature exceeds the phase change temperature of the phase change material 6 but is only slightly hot, the water temperature can also be cooled through the phase change material 6 and the heat conduction component 7. Compared with natural cooling, the cooling efficiency is still improved.

[0045] The phase change material 6 can be an organic fiber phase change material, and can be attached to the inner peripheral wall of the mounting cavity by adhesive bonding, thereby achieving a detachable connection. The cup seat 3 is also detachably connected to the cup shell 2, so the phase change material 6 can be replaced when needed.

[0046] In order to enable the phase change material 6 to absorb and store energy while also heating the inner liner 1 faster and better, the phase change material 6 is connected in pairs and centrally symmetrically in the installation cavity, and two sets of heat conduction components 7 are also provided accordingly.

[0047] To control whether the phase change material 6 heats the inner liner 1, the heat-conducting component 7 is configured to include a first heat-conducting element 71 and a second heat-conducting element 72. The plane of the upper end of the first heat-conducting element 71 coincides with the plane of the lower end of the second heat-conducting element 72. The four side walls of the first heat-conducting element 71 are wrapped with the phase change material 6. The second heat-conducting element 72 is coaxially disposed between the inner liner 1 and the cup shell 2. The cup shell 2 has a sliding channel 21. The second heat-conducting element 72 is connected to a sliding handle 8 that passes through the sliding channel 21 and can slide along the sliding channel 21.

[0048] When the phase change material 6 absorbs heat and needs to transfer it to the inner liner 1, the sliding handle 8 is slid along the sliding channel 21, thereby driving the second heat conductor 72 to move so that the upper end of the first heat conductor 71 coincides with the lower end of the second heat conductor 72. When heat transfer needs to be blocked, the sliding handle 8 is slid in the opposite direction so that the second heat conductor 72 moves away from the first heat conductor 71.

[0049] To prevent excessive heat dissipation from the mounting cavity to the outside through the sliding channel 21, a baffle 9 is connected to the side wall of the second heat conductor 72 to block the sliding channel 21. The height of the baffle 9 corresponds to the height of the sliding channel 21, and the baffle 9 is located near the sliding handle 8. When the sliding handle 8 drives the second heat conductor 72 to rotate, the baffle 9 rotates along with it and blocks the sliding channel 21.

[0050] To prevent the heat generated at the heating end of the thermoelectric cooler 51 from becoming too hot and difficult to dissipate, which could damage the thermoelectric cooler 51, a heat dissipation hole 31 is provided in the cup holder 3 to communicate with the outside.

[0051] To adjust the exposed area of ​​the heat dissipation hole 31 and thus control the amount of heat dissipation, the heat dissipation hole 31 is formed on a portion of the bottom and a portion of the peripheral wall of the cup holder 3. An adjusting sleeve 101 is coaxially rotatably fitted onto the bottom of the cup holder 3. The adjusting sleeve 101 has an adjusting hole 1011 that exposes the heat dissipation hole 31. By rotating the adjusting sleeve 101, the adjusting hole 1011 of the adjusting sleeve 101 is aligned with the position of the heat dissipation hole 31. The smaller the corresponding area, the less heat is dissipated, ensuring that most of the generated heat is absorbed by the phase change material 6.

[0052] To prevent the heat generated by the phase change material 6 from being transferred to the second heat conductor 72 when heating is not required, heat insulation cotton 102 is connected to both sides of the second heat conductor 72. When the second heat conductor 72 is separated from the first heat conductor 71, a distance is maintained between the two phase change materials 6 and each heat insulation cotton 102 in the circumferential direction. Here, circumferential direction refers to the direction along the circumference of a circle.

[0053] To ensure that the heat from the first heat-conducting element 71 can be transferred more fully to the first heat-conducting element 71, the lower end surface area of ​​the second heat-conducting element 72 is larger than the upper end surface area of ​​the first heat-conducting element 71. Therefore, when the sliding handle 8 slides from one end of the sliding channel 21 to the other end, the upper end surface of the first heat-conducting element 71 is completely in contact with the lower end surface of the second heat-conducting element 72.

[0054] To allow people to easily monitor the drinking water temperature, a first temperature sensor (not shown in the figure) is installed at the upper end of the installation cavity near the inner liner 1, so that the temperature detected by the first sensor is close to the water temperature. The cup shell 2 is connected to a display screen 103 that can display the temperature detected by the first temperature sensor.

[0055] To facilitate understanding the ambient temperature between the bottom of the cup holder 3 and the inner liner 1, and thus compare it with the phase change temperature of the phase change material 6, it is convenient to determine whether to open the heat dissipation hole 31 and to what extent. A second temperature sensor (not shown in the figure) is installed in the mounting cavity between the bottom of the cup holder 3 and the inner liner 1. The second temperature sensor is connected to the display screen 103.

[0056] The working process of this utility model:

[0057] When it is necessary to cool the hot water in the inner tank 1, the upper end of the semiconductor cooling chip 51 is cooled by pressing the control switch 106 to control the cooling, thereby achieving cooling. If the water temperature exceeds the phase change temperature of the phase change material 6 but is only slightly hot, it can also be cooled by the heat conduction component 7 and the phase change material 6.

[0058] While the upper end of the semiconductor cooling chip 51 is cooled, heat is generated at the lower end. This heat is absorbed and stored by the phase change material 6. When the water temperature is observed to be lower than the phase change temperature of the phase change material 6 through the display screen 103 and the water needs to be heated, the sliding handle 8 can be slid along the sliding channel 21 to drive the second heat conductor 72 to rotate so that its lower end is in contact with the upper end of the first heat conductor 71. Therefore, the heat of the phase change material 6 can be transferred to the second heat conductor 72, and then transferred to the inner tank 1 by the second heat conductor 72, thereby heating the water in the inner tank 1.

[0059] If the water temperature is lower than the phase change temperature of the phase change material 6 but the temperature to be heated is higher than the phase change temperature, the water can be heated first by the phase change material 6, and then the second heat-conducting element 72 can be separated from the first heat-conducting element 71, and then heated by the semiconductor cooling chip 51.

[0060] If the water temperature is found to be higher than the phase change temperature of the phase change material 6 but heating is still required, the control switch 106 for heating can be pressed to heat the upper end of the semiconductor cooling chip 51, thereby achieving heating.

[0061] The above description is merely a specific example of this utility model and does not constitute any limitation on this utility model. Obviously, those skilled in the art, after understanding the content and principle of this utility model, may make various modifications and changes in form and details without departing from the principle and structure of this utility model. However, these modifications and changes based on the concept of this utility model are still within the protection scope of the claims of this utility model.
