Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and more specifically to an ice container for a water dispenser. Background Art

[0002] At present, most household water dispensers use semiconductor refrigeration, which has the characteristics of simple structure, low vibration and noise, no need for refrigerant, and safety and reliability. It uses the thermoelectric effect of semiconductor materials and realizes the functions of cooling and heating through the action of electric current, providing families with convenient and efficient drinking water solutions.

[0003] At present, household water dispensers generally use semiconductor refrigeration chips as core components, and realize the refrigeration function through the temperature difference effect between the hot and cold ends. In order to enhance the heat exchange effect, the hot and cold ends of the semiconductor refrigeration chip are respectively provided with heat dissipation blocks and refrigeration blocks. As a key component, the refrigeration block is generally made of extruded aluminum alloy thermal conductive material, which has good thermal conductivity and corrosion resistance, and can ensure the refrigeration effect while extending the service life. When the water dispenser is working normally, the refrigeration block is immersed in water, and efficient cooling is achieved through convection, conduction and radiation.

On the other hand, although semiconductor refrigeration chips with large cooling capacity can significantly increase the cooling speed, their cold end temperature is too low, which can easily lead to ice on the surface of the cooling block. The formation of ice layer will not only affect the convection and conduction effects of water and reduce the heat exchange performance of the cooling block, but may also cause the water temperature in the ice tank to gradually rise as the ice layer thickens, thereby affecting the cooling effect of the water dispenser and user experience.

DETAILED DESCRIPTION

[0031] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that the embodiments of the present invention will be more comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, many specific details are provided to provide a full understanding of the implementation of the embodiments of the present invention.

[0032] Existing household water dispensers generally use semiconductor refrigeration chips as core components, and realize the refrigeration function through the temperature difference effect of its hot and cold ends. In order to enhance the heat exchange effect, the hot and cold ends of the semiconductor refrigeration chip are respectively provided with a heat sink and a refrigeration block. When the water dispenser is working normally, the refrigeration block is immersed in water, and efficient cooling is achieved through convection, conduction and radiation. However, for semiconductor refrigeration chips with small cooling capacity, due to their limited refrigeration capacity, the cooling speed of drinking water in the ice tank is relatively slow, which is difficult to meet the user's demand for rapid refrigeration. On the other hand, although semiconductor refrigeration chips with large cooling capacity can significantly increase the cooling speed, their cold end temperature is too low, which easily causes ice to form on the surface of the refrigeration block. The formation of the ice layer will not only affect the convection and conduction effects of water and reduce the heat exchange performance of the refrigeration block, but may also cause the water temperature in the ice tank to gradually rise as the ice layer thickens, thereby affecting the refrigeration effect and user experience of the water dispenser.

[0033] In order to solve the above problems, the present application provides a water dispenser ice bladder, referring to Figures 1 to 4 As shown, it includes a housing 10 and a thermoelectric module 30, and the thermoelectric module 30 is arranged on the side wall of the housing 10. The housing 10 forms a closed space, so that the refrigeration process can be carried out in a relatively stable environment. The material of the housing 10 is usually selected to be corrosion-resistant to ensure refrigeration efficiency and service life.

[0034] The thermoelectric module 30 includes a cooling block 31 and a semiconductor cooling sheet 32 ​​. The cooling block 31 is disposed in the inner cavity of the housing 10 , and the cold end of the semiconductor cooling sheet 32 ​​is in contact with the cooling block 31 .

[0035] The thermoelectric module 30 is the core component of the water dispenser ice tank, and realizes the cooling function by using the thermoelectric effect of the semiconductor cooling sheet 32. The thermoelectric module 30 is designed and installed on the side wall of the housing 10, which can effectively utilize the space and ensure the maximum cooling effect.

[0036] The cooling block 31 is the part of the thermoelectric module 30 that is in direct contact with water and is used to transfer the cold energy generated by the semiconductor cooling sheet 32 ​​to the water. The semiconductor cooling sheet 32 ​​serves as a cold source for the cooling block 31. The semiconductor cooling sheet 32 ​​realizes the cooling function through the temperature difference effect between its cold end and hot end. The cold end is attached to the cooling block 31 and transfers the cold energy to the cooling block 31.

[0037] The refrigeration block 31 includes a base plate 311 and a rib plate 312. One side of the base plate 311 is in contact with the cold end of the semiconductor refrigeration plate 32, and the other side is fixedly connected to the rib plate 312. There are multiple rib plates 312, which are evenly spaced and vertically fixed on the base plate 311.

[0038] The cooling block 31 is composed of a base plate 311 and ribs 312. The base plate 311 is used as a receiving surface for cooling, and is closely attached to the cold end of the semiconductor cooling plate 32 to ensure efficient transmission of cooling. The ribs 312 enhance the heat exchange effect. The ribs 312 are fixed vertically on the base plate 311 at equal intervals to form a plurality of heat exchange channels. These channels increase the contact area between water and the cooling block 31, thereby improving the heat exchange efficiency.

[0039] By optimizing the structural design of the refrigeration block 31, especially increasing the number and reasonable distribution of the ribs 312, the heat exchange area and heat exchange efficiency of the refrigeration block 31 are significantly improved. In this way, even if a semiconductor refrigeration sheet 32 ​​with a small cooling capacity is used, the cooling speed of drinking water can be accelerated by enhancing the heat exchange effect, meeting the user's demand for rapid cooling.

[0040] The water dispenser ice tank provided in the embodiment of the present application not only accelerates the cooling speed of drinking water, but also maintains the stability and durability of the cooling effect by reducing the possibility of ice formation. This not only improves the cooling efficiency, but also enhances the user's drinking experience. By improving the heat exchange efficiency and reducing unnecessary energy loss, it has a significant energy-saving and environmental protection effect.

[0041] In some embodiments of the present application, the thickness of the substrate 311 increases from the edge to the center.

[0042] Specifically, when the cold end of the semiconductor refrigeration plate 32 generates cold energy, the center temperature is lower, and this cold energy is first transferred to the substrate 311. Since the thickness of the substrate 311 gradually increases from the edge to the center, this design enhances the heat exchange effect in the central area, thereby improving the refrigeration efficiency. The increase in the center thickness of the substrate 311 is not only conducive to the transfer of heat, but also significantly enhances the overall structural strength of the refrigeration block 31. During the refrigeration process, due to physical phenomena such as thermal expansion and contraction, the refrigeration block 31 may be subjected to certain stresses. The substrate 311 with a thickened center can better resist these stresses and extend the service life of the refrigeration block 31.

[0043] In traditional designs, the cooling block often has the problem of uneven cooling speed, that is, the cooling speed of the area close to the cold end of the semiconductor cooling plate is faster, while the area far from the cold end is relatively slower. Through the design of the gradual thickness of the substrate 311, the cold amount is more evenly distributed during the transfer process, thereby solving the problem of uneven cooling speed. Due to the increase in the center thickness of the substrate 311, the cold amount is better accumulated and strengthened during the transfer process, thereby improving the cooling efficiency and cooling speed. This can significantly speed up the cooling speed of drinking water, especially for semiconductor cooling plates with small cold amounts.

[0044] In some embodiments of the present application, the thickness of the ribs 312 is alternating between long and short from the edge toward the center of the inner cavity of the shell 10, and the distance between adjacent ribs 312 gradually increases from the edge to the center.

[0045] In the embodiment of the present application, the thickness of the ribs 312 varies according to a certain rule. Specifically, the thickness of the ribs 312 is long and short from the edge toward the center of the inner cavity of the shell 10, that is, some ribs are relatively long, while adjacent ribs are relatively short. This size design increases the surface area of ​​the ribs 312 and optimizes the fluid dynamics characteristics inside the refrigeration block 31.

[0046] Specifically, when water flows inside the refrigeration block 31, the ribs 312 with different lengths can guide the water flow to form more complex flow patterns, such as vortex, mixing, etc. These flow patterns help to increase the contact area and contact time between water and the ribs 312, thereby improving the heat exchange efficiency. At the same time, the vortex and mixing effects can also promote the heat transfer inside the water, making the water temperature more uniform. Due to the thickness change of the ribs 312, the heat exchange area inside the refrigeration block 31 has been significantly increased. This not only improves the heat exchange rate between the refrigeration block 31 and the water, but also significantly improves the refrigeration efficiency. Under the same cooling capacity, this design can reduce the water temperature faster and meet the user's demand for rapid cooling.

[0047] In addition, since the center temperature of the refrigeration block 31 is lower, the edge spacing of the ribs 312 is small and the heat exchange area is large, and the large center spacing is conducive to convective heat exchange, reducing the risk of local overcooling. At the same time, the design of the ribs 312 also helps to promote water convection and mixing, reducing the possibility of ice formation. Even in the case of large cooling capacity, the problem of ice on the surface of the refrigeration block 31 can be effectively avoided.

[0048] It is understandable that in traditional designs, ribs often have a fixed thickness and length, which limits the increase in heat exchange area and the improvement in heat exchange efficiency. By designing the ribs 312 with alternating lengths, the heat exchange area is increased, the fluid dynamics are optimized, and the problem of low heat exchange efficiency is solved. The design of the ribs 312 with alternating lengths can also optimize the water flow path and reduce the risk of water blockage inside the refrigeration block 31. This helps to keep the water flow unobstructed and improve the reliability and durability of the refrigeration block 31.

[0049] In some embodiments of the present application, the thermoelectric module also includes a heat sink 33 and a heat dissipation fan 34; the hot end of the semiconductor refrigeration sheet 32 ​​is in contact with the heat sink 33; the heat dissipation fan 34 is arranged on the side of the heat sink 33 facing away from the semiconductor refrigeration sheet 32, and the wind direction of the heat dissipation fan 34 is to blow air outward from the side close to the heat sink 33.

[0050] The heat sink 33 is usually made of a material with high thermal conductivity, such as aluminum alloy or copper alloy, to ensure that heat can be quickly and effectively transferred from the hot end of the semiconductor cooling plate 32 to the heat sink 33. The surface area of ​​the heat sink 33 is usually designed to be larger to increase the contact area with the air, thereby improving the heat dissipation efficiency. The wind direction of the heat dissipation fan 34 is set to blow air outward from the side close to the heat sink 33, that is, forced convection heat dissipation. The heat dissipation fan 34 accelerates the air flow to quickly take away the heat on the heat sink 33, further improving the heat dissipation efficiency. This design not only ensures the stability of the thermoelectric module 30 when running at high load, but also extends the service life of the semiconductor cooling plate 32.

[0051] Through the synergistic effect of the heat sink 33 and the heat dissipation fan 34, the heat dissipation effect of the thermoelectric module 30 is significantly improved. The heat generated by the hot end of the semiconductor cooling plate 32 is quickly transferred to the heat sink 33 and taken away by the forced convection heat dissipation of the heat dissipation fan 34. This not only reduces the operating temperature of the semiconductor cooling plate 32, but also improves its cooling efficiency, so that the water dispenser ice tank can still maintain stable cooling performance during long-term operation.

[0052] In the existing water dispenser ice tank, the hot end of the semiconductor refrigeration plate 32 often only relies on natural heat dissipation or simple heat sinks for heat dissipation. This heat dissipation method may be sufficient under low heat load, but under high load or long-term operation, insufficient heat dissipation will cause the temperature of the semiconductor refrigeration plate 32 to rise, thereby affecting its cooling efficiency and stability. By introducing the heat dissipation block 33 and the heat dissipation fan 34, the embodiment of the present application effectively solves this problem and ensures the stability and cooling efficiency of the thermoelectric module 30 under high load operation. The addition of the heat dissipation block 33 and the heat dissipation fan 34 in the embodiment of the present application not only improves the heat dissipation efficiency of the thermoelectric module 30, but also indirectly improves the cooling efficiency and stability. Since the operating temperature of the semiconductor refrigeration plate 32 is reduced, its cooling efficiency is improved, thereby accelerating the cooling speed of the drinking water. At the same time, the stable heat dissipation effect also ensures the reliability of the thermoelectric module 30 under long-term operation.

[0053] In some embodiments of the present application, a graphene-based composite antibacterial coating is provided on the surface of the refrigeration block 31, and the coating is composed of a binary composite material of TiO2 and graphene, or a ternary composite material of TiO2, Ag3PO4 and graphene.

[0054] TiO2 is a widely recognized antibacterial material, and its photocatalytic activity can decompose organic matter and kill bacteria. Under ultraviolet light, TiO2 can produce free radicals with strong oxidizing properties, which can destroy the cell wall and DNA of bacteria, thereby achieving an antibacterial effect. Ag3PO4 is a material with high antibacterial properties, and its antibacterial mechanism is mainly achieved by releasing silver ions. Silver ions can interfere with the metabolic process of bacteria and inhibit their growth and reproduction. When TiO2 is used in combination with Ag3PO4, the two can produce a synergistic antibacterial effect, significantly improving the antibacterial properties of the coating.

[0055] In the ice tank of the water dispenser, the surface of the refrigeration block 31 easily becomes a breeding ground for bacteria and microorganisms. In the embodiment of the present application, by coating a graphene-based composite antibacterial coating, the growth of these bacteria and microorganisms can be effectively killed and inhibited, thereby solving the problem of bacterial growth and improving the sanitary safety of drinking water. By combining TiO2 (or TiO2 and Ag3PO4) with graphene, a graphene-based composite antibacterial coating with excellent antibacterial properties and good thermal conductivity and mechanical properties is formed. This coating can not only effectively kill and inhibit the growth of bacteria, but also quickly respond to temperature changes in the refrigeration block 31 to maintain the stability of the refrigeration efficiency.

[0056] At the same time, the excellent thermal conductivity of graphene enables the coating to quickly respond to temperature changes in the refrigeration block 31 and maintain stable refrigeration efficiency. This helps ensure that the ice tank of the water dispenser can maintain stable refrigeration performance during long-term operation and improve the user's drinking experience. The addition of graphene also enhances the mechanical strength and wear resistance of the coating, allowing the coating to resist wear and scratches in daily use and extend its service life. The antibacterial properties of TiO2 and Ag3PO4 give the coating a wide antibacterial spectrum and efficient antibacterial effect. This helps ensure that the ice tank of the water dispenser can maintain excellent antibacterial properties under different water qualities and usage environments.

[0057] In some embodiments of the present application, a photocatalytic lamp bead 40 is further disposed on the housing 10 , and the photocatalytic lamp bead 40 is disposed opposite to the thermoelectric module 30 .

[0058] The photocatalytic lamp beads 40 and the thermoelectric module 30 are arranged relative to each other, ensuring that the light emitted by the photocatalytic lamp beads 40 can directly irradiate the surface of the refrigeration block 31 of the thermoelectric module 30, especially those areas coated with the graphene-based composite antibacterial coating. The light emitted by the photocatalytic lamp beads 40 can activate TiO2 in the graphene-based composite antibacterial coating, thereby initiating a series of photocatalytic reactions. These reactions can decompose organic matter, kill bacteria, and produce free radicals with cleaning and purification effects.

[0059] The relative arrangement of the photocatalytic lamp beads 40 and the thermoelectric module 30 not only realizes the photocatalytic effect, but also forms a synergistic effect. On the one hand, the photocatalytic effect can enhance the antibacterial performance of the graphene-based composite antibacterial coating and further improve the hygienic safety of the surface of the refrigeration block 31.

[0060] In some embodiments of the present application, a water inlet 11, a water outlet pipe 12 and a sewage outlet 13 are also provided on the shell 10, and the water inlet 11, the water outlet pipe 12 and the sewage outlet 13 are all connected to the inner cavity of the shell 10; the water inlet 11 and the water outlet pipe 12 are arranged on the same side of the shell 10, and the sewage outlet 13 is arranged on the side opposite to the water inlet 11 and the water outlet pipe 12.

[0061] Specifically, the water inlet 11, the water outlet 12 and the sewage outlet 13 are all arranged on the shell 10 as channels for exchanging fluid with the external environment, and are connected with the inner cavity of the shell 10, ensuring that water can smoothly enter, flow out and be discharged from the shell 10, meeting the normal operation requirements of the water dispenser ice tank.

[0062] The water inlet 11 and the water outlet 12 are arranged on the same side of the housing 10. This layout not only reduces the complexity of the installation process, but also allows users to connect and operate more conveniently. The sewage outlet 13 is cleverly arranged on the side opposite to the water inlet 11 and the water outlet 12, which helps to form an effective fluid channel during the sewage discharge process, ensuring that sewage can be smoothly discharged from the housing 10 to avoid accumulation and contamination inside. At the same time, the relative position of the sewage outlet 13 also helps to reduce the residence time of the fluid inside the housing 10 and reduce the risk of contamination.

[0063] In some embodiments of the present application, a water temperature sensor 50 is also provided on the shell 10, and the water temperature sensor is electrically connected to the thermoelectric module 30; the water temperature sensor 50 is used to monitor the water temperature in the inner cavity of the shell 10 to obtain temperature data, and transmit the temperature data to the thermoelectric module 30; the thermoelectric module 30 is configured to: receive temperature data, and start or pause refrigeration according to the temperature data.

[0064] The thermoelectric module 30 is also configured to stop cooling when the temperature data is lower than a preset temperature, and start cooling when the temperature data is higher than a preset temperature.

[0065] Specifically, when the temperature data fed back by the water temperature sensor 50 is lower than the comfortable or safe water temperature threshold preset by the system, the thermoelectric module 30 will determine that the current water temperature meets the use requirements, and will therefore stop the cooling operation to avoid unnecessary energy consumption while maintaining the water temperature stable. Secondly, when the temperature data is higher than the preset temperature, the thermoelectric module 30 can quickly identify the risks or discomfort that may be caused by the high water temperature, and then start the cooling function to ensure the comfort and safety of the environment inside the housing 10 by adjusting the water temperature to the preset level.

[0066] The embodiment of the present application realizes intelligent monitoring and management of water temperature through the coordinated work of the water temperature sensor 50 and the thermoelectric module 30, and can automatically adjust the water temperature without human intervention, thereby improving the level of automation and convenience.

[0067] In some embodiments of the present application, a heat insulation layer 20 is also included, and the heat insulation layer 20 is wrapped around the outside or inside of the shell 10. It can effectively block the heat exchange between the inside and outside of the shell 10, which plays a vital role in preventing external heat from invading the inside and preventing internal cold from being lost to the outside. This thermal isolation effect ensures the stability of the internal environment of the shell 10, especially when the thermoelectric module 30 is operating in cooling or heating mode, it can significantly improve energy efficiency.

[0068] The material of the heat insulation layer 20 needs to have the characteristics of high thermal resistance, low thermal conductivity, good mechanical strength and weather resistance, etc. Common heat insulation materials include foam plastics, aerogels, glass fibers, etc., and this application does not make specific restrictions.

[0069] The heat insulation layer 20 can be wrapped on the outside or inside of the housing 10. Specifically, the external wrapping method can directly reduce the impact of the external environment on the internal temperature of the housing 10, and is suitable for systems that require long-term stable operation and are sensitive to changes in the external environment. The internal wrapping method focuses more on protecting the internal components of the housing 10 from temperature changes, especially providing better protection under extreme conditions.
