[0041] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0042] refer to Figure 1 and Figure 2 In some specific embodiments of this utility model, a cooling device 200 is provided. The cooling device 200 can be installed in the toilet seat 100. Specifically, the seat 100 may include a first cover 110 and a second cover 120, as well as a cavity formed by the two covers for housing the cooling device 200. Among the first cover 110 and the second cover 120, the one facing the user's back when the seat 100 is flipped up is provided with an air outlet 121. When the cooling device 200 is installed in the seat 100, cold air can be blown from the air outlet 121 to the user's back, thereby more effectively reducing the user's perceived temperature and improving the user experience.

[0043] refer to Figures 2 to 6 The cooling device 200 provided in this embodiment of the present invention includes a housing 210, an air supply mechanism, a cold storage component 230, and a cooling module 240. The housing 210 is sequentially provided with an air inlet 213, an air duct 214, and an air outlet 216. Airflow can enter the air duct 214 from the air inlet 213 and then flow out from the air outlet 216. The housing 210 also has at least one accommodating cavity 215, and heat transfer can occur between the accommodating cavity 215 and the air duct 214. The air supply mechanism is used to deliver airflow into the air duct. It can be a blower 220, a fan, an exhaust fan, etc. The air supply mechanism can also be set in various ways. For example, when the air supply mechanism is a blower 220 or a fan, the air supply mechanism is set at the air inlet 213. When the air supply mechanism is an exhaust fan, the air supply mechanism is set at the air outlet 216 or in the air duct 214 to control the airflow into the air duct 214. Therefore, when the user turns on the air supply function, the air supply mechanism is activated, and air enters the air duct 214 from the air inlet 213. The cold storage component 230 is disposed in the accommodating cavity 215. The refrigeration module 240 can be a semiconductor refrigeration chip, and the cold storage component 230 is thermally conductive. The refrigeration module 240 and the cold storage component 230 are thermally connected. For example, the refrigeration module 240 and the cold storage component 230 are directly attached to each other, or indirectly connected through other thermally conductive components, as long as heat conduction can be achieved between the refrigeration module 240 and the cold storage component 230.

[0044] In this embodiment, the cooling module 240 can be continuously operated or periodically activated for cooling, and the user can control the start time of cooling. When the cooling module 240 is activated, the heat in the cold storage component 230 can be transferred to the cooling module 240, causing the temperature of the cold storage component 230 to continuously decrease until it is lower than the temperature of the airflow in the air duct 214. Furthermore, since heat can be transferred between the cold storage component 230 disposed in the accommodating cavity 215 and the air duct 214, the cold storage component 230 absorbs heat from the air duct 214. Therefore, when the airflow delivered by the air supply mechanism flows through the air duct 214, the airflow will exchange heat with the cold storage component 230, thereby reducing the airflow temperature and forming a low-temperature airflow that passes through the air outlet 216 and the air supply outlet 121 successively, and finally blows out towards the user's back, achieving cold air output.

[0045] It is understandable that the air inlet 213, air duct 214, and air outlet 216 can be arranged on the same straight line, that is, the air duct 214 is set as a straight air duct 214, in which case the pressure loss when the airflow passes through is minimized. Alternatively, the air duct 214 can be set as a zigzag air duct 214 with multiple different bending angles, that is, the air inlet 213, air duct 214, and air outlet 216 are not on the same straight line. In this case, the volume of the housing 210 is smaller, which can be conveniently installed in the cover plate 100 and avoid the cover plate 100 from being too large.

[0046] It is understandable that the cold storage component 230 can contain a non-insulating material, such as water or other fluids with different freezing points. In this case, the outer shell of the cold storage component 230 is thermally conductive, allowing heat to be transferred to the contained material. The cold storage component 230 can also be a thermally conductive solid component, such as a thermally conductive metal. That is, as long as the cold storage component 230 can transfer heat with the cooling module 240 to reduce its own temperature and absorb heat from the airflow in the air duct 214, the specific configuration is not limited here.

[0047] It should be noted here that heat transfer can occur between the accommodating cavity 215 and the air duct 214. This means that the two are arranged in a corresponding manner, and heat can be transferred and moved between the accommodating cavity 215 and the air duct 214. Therefore, the accommodating cavity 215 and the air duct 214 can be directly connected or separated by a heat-conducting baffle. No specific limitation is made here.

[0048] In some specific embodiments of this utility model, at least the portion of the housing 210 that forms the accommodating cavity 215 is made of thermal insulation material. This isolates the cold storage component 230 from the external environment, preventing unnecessary energy consumption and improving the energy efficiency of the cooling device 200. Furthermore, thanks to the thermal insulation material, even if the refrigeration module 240 stops working for a short period or experiences a power outage, the cold storage component 230 will not rapidly absorb external heat, thus achieving a cold storage effect. This avoids the refrigeration module 240 from continuously operating to maintain the low temperature of the cold storage component 230, saving energy.

[0049] Furthermore, the entire housing 210 can be made of insulation material, thereby further preventing heat transfer between the airflow in the duct 214 and the external environment, thus further improving the energy efficiency of the cooling device 200.

[0050] Understandably, regardless of whether the housing 210 is partially or entirely composed of insulation material, for components in the cooling device that require heat dissipation, corresponding through holes connecting to the outside can be provided in the housing 210 to expose the parts that need heat dissipation to the external environment, thereby preventing the heat that needs to be transferred from continuously circulating in the housing 210 and reducing energy utilization efficiency.

[0051] Further reference Figure 2 The housing 210 can be formed by covering the first housing 211 and the second housing 212, and the two housings 210 enclose the air inlet 213, the air outlet 216, the air duct 214 and the accommodating cavity 215, etc.

[0052] refer to Figure 2 , Figure 5 and Figure 7 In some specific embodiments of this utility model, a condensation assembly 250 is further included in the housing 210. The condensation assembly 250 includes a heat-conducting plate 251 and at least one fin 252, wherein the heat-conducting plate 251 and the fin 252 are connected and can transfer heat between them. Specifically, the fin 252 is disposed in the air duct 214 and extends along the direction of the air duct 214, while the heat-conducting plate 251 passes through the accommodating cavity 215. The refrigeration module 240 and the cold storage component 230 are respectively connected to both sides of the heat-conducting plate 251.

[0053] In this embodiment, the cooling module 240 absorbs heat from the cold storage component 230 through the heat-conducting plate 251, causing it to gradually solidify. On the other hand, it also absorbs heat from the condensing component 250, causing the temperature of the fins 252 disposed in the air duct 214 to gradually decrease. At this time, when the airflow flows through the air duct 214, not only does the cold storage component 230 absorb heat from the airflow, but when the airflow flows over the surface of the fins 252 and comes into contact with the fins 252, it will also be absorbed by the fins 252, thereby achieving a two-stage heat absorption process for the airflow, which more effectively improves the speed and efficiency of airflow cooling.

[0054] It is understood that multiple fins 252 can be configured, wherein multiple fins 252 are arranged sequentially at intervals along a direction perpendicular to the air duct 214, and multiple fins 252 are arranged adjacent to each other to form multiple air passages 2141, thereby further increasing the contact area between the airflow and the fins 252 and improving the heat exchange efficiency between the fins 252 and the airflow.

[0055] It is understandable that multiple heat-conducting plates 251 can be used. For example, heat-conducting plates 251 connected to both sides of the fins 252 can be provided, meaning two heat-conducting plates 251 are distributed on both sides of the air duct 214. In this case, the number of cooling modules 240 and cold storage components 230 is consistent with the number of heat-conducting plates 251, also distributed on both sides of the air duct 214 and connected through corresponding heat-conducting plates 251. Furthermore, multiple heat-conducting plates 251, cooling modules 240, and cold storage components 230 can be provided and asymmetrically arranged on both sides of the air duct 214. Thus, cooling can be achieved simultaneously by two or more cooling modules 240, improving the cooling speed and efficiency of the air in the air duct 214.

[0056] refer to Figure 6 and Figure 7 In some specific embodiments of this utility model, the fins 252 are arranged in a wave shape along the air inlet and outlet direction of the air duct 214. By setting the fins 252 in a wave shape, the contact area between the airflow and the fins 252 and the residence time of the airflow in the air duct 214 are extended without significantly increasing the loss of airflow kinetic energy, thereby increasing the contact and heat exchange time between the two and helping to further reduce the airflow temperature.

[0057] It is understandable that when multiple fins 252 are configured, the multiple air passages 2141 formed by the multiple adjacent fins 252 also have a wave shape.

[0058] refer to Figure 2 Figure 4 and Figure 5In some specific embodiments of this utility model, the cooling module 240 includes a hot end 242 and a cold end 241. For example, when the cooling module 240 is a semiconductor cooling chip, when the cooling module 240 is working, the heat from the cold end 241 will be continuously transferred to the hot end 242. The cooling module 240 is connected to the heat-conducting plate 251 through the cold end 241, thereby absorbing the heat from the heat-conducting plate 251 and transferring it to the hot end 242.

[0059] Meanwhile, in order to accelerate the heat dissipation of the hot end 242 and ensure the efficiency of the hot end 242 in absorbing the heat from the cold end 241, the cooling device 200 is also equipped with a heat exchange device 260, which is connected to the hot end 242 of the refrigeration module 240 and is used to absorb the heat from the hot end 242.

[0060] In some embodiments, the heat exchange device 260 may be an air supply mechanism to accelerate the flow of air near the hot end 242, thereby removing some of the heat on the hot end 242, or it may be a heat exchange mechanism with built-in liquid heat absorption.

[0061] In this embodiment, it is understood that, regardless of whether a heat dissipation mechanism or an air supply mechanism is provided, when the housing 230 is made of thermal insulation material, the housing 230 needs to be adapted to have a channel connecting to the outside so that hot air can leave the housing 230 to transfer heat, or the heat dissipation mechanism can be exposed to the outside to dissipate heat.

[0062] refer to Figure 8 In some specific embodiments of this utility model, the heat exchange device 260 includes an inlet 261, a heat exchange chamber 262, and an outlet 263 connected in sequence. At least the heat exchange chamber 262 is connected to the hot end 242 of the cooling air device 200, and heat conduction can occur between the two. For example, at least the heat exchange chamber 262 in the heat exchange device 260 is made of a thermally conductive material. When the liquid used for heat absorption enters the heat exchange chamber 262 from the inlet 261, the heat absorbed by the heat exchange device 260 from the hot end 242 can be transferred through the outer shell of the heat exchange chamber 262 to the liquid used for heat absorption, and discharged through the outlet 263, thereby transferring the heat of the hot end 242 and cooling it down.

[0063] In this embodiment, a separate water source can be connected to the heat exchange device 260 to provide water flow for heat absorption. The heat exchange device 260 can also be connected to the toilet tank to use the water flow in the tank for heat absorption. The water flow after absorbing heat can be directly sent back to the tank for toilet flushing, thus recycling and saving water.

[0064] In some specific embodiments of this utility model, when the number of cooling modules 240 is multiple, the number of heat exchange devices 260 is also multiple, thereby achieving efficient heat dissipation.

[0065] Furthermore, multiple heat exchange devices 260 can be connected by pipes. That is, along the flow direction of the heat exchange liquid, the outlet 263 of the previous heat exchange device 260 is connected to the inlet 261 of the next heat exchange device 260 through a pipe, so that the liquid that has absorbed some heat in the previous heat exchange device 260 enters the next heat exchange device 260 to continue heat exchange, thereby improving the utilization efficiency of the heat exchange liquid. At this time, grooves can be provided on the first housing 211 or the second housing 212 for pipe embedding, so as to avoid the internal pipeline of the cold air device 200 being messy, which is not conducive to installation and subsequent maintenance.

[0066] refer to Figure 8 In some specific embodiments of this utility model, the heat exchange chamber 262 includes at least one baffle plate 2621 arranged along the liquid inlet direction, wherein the baffle plate 2621 can also conduct heat. Specifically, there can be multiple baffle plates 2621, which are arranged sequentially at intervals along a direction perpendicular to the liquid inlet direction. Thus, the multiple baffle plates 2621 divide the heat exchange chamber 262 into multiple liquid flow channels 2622, thereby increasing the contact area between the liquid entering the heat exchange chamber 262 and the baffle plates 2621, allowing the liquid to have a longer contact time with the baffle plates 2621, resulting in higher heat exchange capacity and improved heat exchange efficiency.

[0067] refer to Figure 3 In some specific embodiments of this utility model, a hinged door 217 and a motor 218 are also provided on the air inlet 213 and / or air outlet 216, wherein the motor 218 is used to control the hinged door 217. Specifically, when the hinged door 217 and the motor 218 are only provided at the air inlet 213, the air inlet 213 can be controlled; when the hinged door 217 and the motor 218 are only provided at the air outlet 216, the opening and closing of the air outlet 216 can be controlled. Thus, not only can the air outlet of the cover 100 be controlled, but the air duct 214 can also be closed when the cooling device 200 is not in use, preventing external dust from entering the air duct 214 and affecting the cleanliness of subsequent air outlets, and preventing external heat from entering the air duct 214 through the air inlet 213 or air outlet 216 and affecting the heat preservation effect of the housing 210.
