Description

Technical Field

[0001] This utility model relates to the field of furniture technology, and in particular to a water-cooled and heated mattress that does not produce condensation. Background Technology

[0002] Water-cooled heated mattresses are products designed to warm the bed in winter and cool it in summer. They mainly consist of two parts: the main unit and the mattress (with a built-in hot water pipe that allows cold or hot water to circulate within it).

[0003] Existing water-cooled and heated mattresses have the following problems:

[0004] Low cooling efficiency: Hot water pipes generally adopt a spiral or serpentine pipe layout, which only forms a linear cold source. The contact area between the pipe and the mattress is small, requiring lower water temperature and higher power to maintain the cooling effect, resulting in high energy consumption and loud noise from the main unit.

[0005] Condensation issue: Low-temperature pipes exposed to air will produce condensation, causing the mattress to become damp and prone to mold, affecting normal use.

[0006] Uneven temperature distribution: Hot and cold temperatures are concentrated near the pipes, with significant local differences in temperature, which affects the user experience.

[0007] Therefore, there are still shortcomings and deficiencies in the existing technology, and how to provide a water-cooled heated mattress without condensation is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0008] The purpose of this invention is to provide a water-cooled heated mattress that does not produce condensation, thus solving the technical problems of low cooling efficiency, condensation, and uneven temperature distribution in existing water-cooled heated mattresses.

[0009] To achieve the above objectives, this utility model provides a condensation-free water-cooled and heated mattress, comprising:

[0010] The foamed layer with an open area ratio of ≥50% has channels on its surface;

[0011] An airbag material sealing layer encapsulating the foam layer;

[0012] A liquid or gel-like thermally conductive medium filled within the sealing layer of the airbag material;

[0013] A circulating water pipe is embedded in the channel and in close contact with the foam layer, and the circulating water pipe is wrapped with the heat-conducting medium.

[0014] Preferably, the thermally conductive medium is deionized water or silicone-based gel.

[0015] Preferably, the foam layer and the airbag material sealing layer are bonded together by vacuum hot pressing.

[0016] Preferably, it also includes a water-cooled heating unit connected to the inlet and outlet of the circulating water pipe.

[0017] Preferably, the channel comprises:

[0018] First main passage;

[0019] Second main passage;

[0020] The first secondary channel is connected at both ends to the first main channel and the second main channel, respectively.

[0021] The second auxiliary channel is connected to the first main channel and the second main channel at both ends, respectively.

[0022] The inlet end of the circulating water pipe is one end of the first main channel / second main channel, and the outlet end of the circulating water pipe is one end of the second main channel / first main channel.

[0023] Preferably, the first sub-channel and the second sub-channel are S-shaped.

[0024] Compared to the aforementioned background technology, the condensation-free water-cooled heated mattress provided by this utility model adopts a composite heat conduction structure. The synergistic design of a high-porosity foam layer, embedded circulating water pipes, and a heat-conducting medium transforms a linear cold source into a planar heat exchange, resulting in uniform temperature distribution, improved heat diffusion efficiency, and enhanced user experience. Furthermore, it eliminates the need for lower water temperatures and higher power to maintain cooling performance. Because the circulating water pipes are completely embedded in the foam layer and encased in the heat-conducting medium, they are isolated from the outside air, preventing condensation caused by temperature differences. This eliminates condensation, preventing the mattress from easily becoming moldy due to dampness and allowing for long-term use. Attached Figure Description

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] This utility model provides a condensation-free water-cooled heated mattress, which adopts a composite heat conduction structure to transform the linear cold source into a planar heat exchange, thereby improving the efficiency of cold and heat diffusion, reducing the energy consumption and noise of the water-cooled heated unit 50, and eliminating condensation.

[0033] Please refer to this as well. Figures 1 to 3 The water-cooled and heated mattress without condensation provided by this utility model includes a foam layer 10 with an open porosity of ≥50%, and channels 11 on the surface of the foam layer 10; an airbag material sealing layer 20 enclosing the foam layer 10; a liquid or gel-like heat-conducting medium 30 filled in the airbag material sealing layer 20; and a circulating water pipe 40 embedded in the channels 11 and in close contact with the foam layer 10. The circulating water pipe 40 is enclosed by the heat-conducting medium 30.

[0034] The porosity mentioned in this article refers to the proportion of interconnected pores per unit volume or unit area in the foamed layer 10; specifically, it reflects the proportion of the number or volume of open pores in the foamed layer 10 relative to the total volume or total area.

[0035] The water-cooled heated mattress employs a composite heat conduction structure. The synergistic design of the high-porosity foam layer 10, embedded circulating water pipes 40, and heat-conducting medium 30 transforms a linear cold source into a planar heat exchange, resulting in uniform temperature distribution, improved heat diffusion efficiency, and enhanced user experience. Because the circulating water pipes 40 are completely embedded in the foam layer 10 and encased in the heat-conducting medium 30, they are isolated from the outside air, eliminating condensation caused by temperature differences. This prevents the mattress from easily becoming moldy due to dampness, allowing for long-term use.

[0036] In cooling mode, cold water circulates in the circulating water pipe 40. The cooling energy is transferred through the pipe wall of the circulating water pipe 40 to the surrounding foam layer 10 and heat-conducting medium 30. The heat-conducting medium 30 uses its fluidity to evenly diffuse the cooling energy to the entire mattress surface, so that the temperature in all places is basically the same.

[0037] In heating mode, hot water circulates within the circulating water pipe 40. Heat is transferred through the pipe wall of the circulating water pipe 40 to the surrounding foam layer 10 and heat-conducting medium 30. The heat-conducting medium 30 uses its fluidity to evenly diffuse heat to the entire mattress surface, avoiding localized overheating.

[0038] Specifically, the foam layer 10 serves as the mattress base and can be made of polyurethane foam. The total length of the channel 11 is 40-60 meters, which can be set according to actual needs.

[0039] The circulating water pipe 40 is embedded in the channel 11 and fixed by heat sealing, snap-fit ​​or adhesive to ensure that the pipe is in close contact with the foam layer 10. The circulating water pipe 40 is a flexible hose containing materials such as silicone, PVC, graphene composite PVC, and graphene composite silicone.

[0040] The airbag material sealing layer 20 comprises nylon fabric, polyamide fabric, polyurethane (TPU), polyamide 66, PET polyester, or other composite materials. The thickness of the airbag material sealing layer 20 is 0.5-2mm. The airbag material sealing layer 20 completely seals the upper and lower surfaces of the foam layer 10, with an inlet and outlet reserved at only one end for the inlet and outlet of the circulating water pipe 40 to pass through.

[0041] After the airbag material sealing layer 20 wraps the foam layer 10, the heat-conducting medium 30 is injected into the cavity of the airbag material sealing layer 20, so that the heat-conducting medium 30 wraps the circulating water pipe 40 and the pores of the foam layer 10.

[0042] Preferably, in this embodiment, the filling rate of the heat-conducting medium 30 is ≥95%. With this setting, the filling degree of the heat-conducting medium 30 is relatively high, and the heat-conducting medium 30 can fully wrap the pores of the pipe and the foam layer 10 to ensure the heat conduction effect.

[0043] Preferably, in this embodiment, the thermally conductive medium 30 is deionized water or silicone-based gel, which has better thermal conductivity. That is, the liquid thermally conductive medium 30 is deionized water, and the gel thermally conductive medium 30 is silicone-based gel.

[0044] Preferably, in this embodiment, the foam layer 10 and the airbag material sealing layer 20 are bonded together by vacuum hot pressing to avoid air bubble residue.

[0045] Please refer to this as well. Figures 1 to 3 The water-cooled heated mattress without condensation provided by this utility model also includes a water-cooled heated main unit 50 connected to the inlet and outlet of the circulating water pipe 40. The water-cooled heated main unit 50 is the core control device of the water-cooled heated mattress, capable of heating and cooling the water in the internal water tank, and has a built-in water pump that can deliver cold or hot water to the mattress. By heating or cooling the circulating water, the mattress temperature is regulated, combining heating and cooling functions to achieve intelligent temperature control.

[0046] Please refer to this as well. Figures 1 to 3 The channel 11 includes a first main channel 111, a second main channel 112, a first auxiliary channel 113, and a second auxiliary channel 114.

[0047] The two ends of the first secondary channel 113 are connected to the first main channel 111 and the second main channel 112, respectively; the two ends of the second secondary channel 114 are connected to the first main channel 111 and the second main channel 112, respectively.

[0048] The inlet of the circulating water pipe 40 is one end of the first main channel 111 / the second main channel 112, and the outlet of the circulating water pipe 40 is one end of the second main channel 112 / the first main channel 111.

[0049] The first secondary channel 113 and the second secondary channel 114 are roughly serpentine, that is, they can be set as S-shaped. Since the shape of the circulating water pipe 40 matches the shape of the channel 11, this arrangement can increase the contact area between the circulating water pipe 40 and the foam layer 10, thereby improving the heat conduction efficiency. Optionally, the porosity of the foam layer 10 is set in a gradient, that is, along the thickness direction of the mattress, the porosity of the foam layer 10 gradually decreases from the side closer to the circulating water pipe 40 to the side in contact with the human body.

[0050] This design enhances the heat exchange efficiency between the heat-conducting medium 30 and the pipe through the high-aperture area, while reducing the rapid transfer of heat to the human body through the low-aperture area, thus avoiding hot and cold stimulation, achieving dynamic temperature buffering, and improving physical comfort.

[0051] Optionally, a diversion valve may be added to the circulating water pipe 40. The diversion valve is used to dynamically adjust the water flow path according to the water temperature and user pressure distribution.

[0052] With this setting, when the user is lying down, the flow rate of the branch circuit in the pressure area can be automatically increased to avoid uneven local temperature.

[0053] Optionally, a flexible fiber optic sensor array can be embedded in the foam layer 10 to monitor the user's body surface temperature, humidity and pressure distribution in real time and provide feedback through an APP.

[0054] This setup automatically adjusts water temperature and flow to prevent localized frostbite from low temperatures or burns from high temperatures. The data can also be linked to smart home systems (such as air conditioners and humidifiers) to achieve overall optimization of the sleep environment.

[0055] When in use, in cooling mode, the cold water output by the water-cooled heating unit 50 circulates in the circulating water pipe 40. The cooling energy is transferred through the pipe wall of the circulating water pipe 40 to the surrounding foam layer 10 and heat-conducting medium 30. The heat-conducting medium 30 uses its fluidity to evenly diffuse the cooling energy to the entire mattress surface, so that the temperature in all places is basically the same.

[0056] In heating mode, the hot water output by the water-cooled heating unit 50 circulates in the circulating water pipe 40. The heat is transferred through the pipe wall of the circulating water pipe 40 to the surrounding foam layer 10 and heat-conducting medium 30. The heat-conducting medium 30 uses its fluidity to evenly diffuse the heat to the entire mattress surface, avoiding local overheating.

[0057] The water-cooled heated mattress provided by this utility model, which eliminates condensation, adopts a composite heat conduction structure. The synergistic design of the high-porosity foam layer 10, the embedded circulating water pipe 40, and the heat-conducting medium 30 transforms a linear cold source into a planar heat exchange, improving heat diffusion efficiency. Due to the good heat conduction of the water-cooled heated mattress, the cooling capacity requirement of the water-cooled heating unit 50 is reduced, thus decreasing energy consumption and noise. Because the circulating water pipe 40 is completely embedded in the foam layer 10 and wrapped by the heat-conducting medium 30, it is isolated from the outside air, eliminating condensation caused by temperature differences. This prevents the mattress from easily becoming moldy due to dampness, allowing for long-term use.

[0058] Actual testing shows that the water-cooled and heated mattress provided by this invention, which eliminates condensation, improves the surface temperature uniformity of the mattress by 60% and reduces the power consumption of the water-cooled and heated main unit by 40% under the same cooling capacity; no condensation is generated after 8 hours of continuous operation, and the mattress humidity remains ≤50%.

[0059] In addition to the condensation-free water-cooled heated mattresses disclosed in the above embodiments, this utility model also provides a method for processing condensation-free water-cooled heated mattresses, including the following processes:

[0060] S1. Select a foam layer 10 with an open porosity of ≥50% as the mattress base, and open channels 11 on the surface of the foam layer 10;

[0061] S2. Embed the circulating water pipe 40 into the channel 11 of the foam layer 10 and fix it by heat sealing, snap fastening or adhesive to ensure that the circulating water pipe 40 is in close contact with the foam layer 10.

[0062] S3. Use the airbag material sealing layer 20 to completely seal the upper and lower surfaces of the foam layer 10;

[0063] S4. Inject liquid or gel-like heat-conducting medium 30 into the cavity wrapped by the airbag material sealing layer 20, so that the circulating water pipe 40 is wrapped by the heat-conducting medium 30.

[0064] S5. The airbag material sealing layer 20 is bonded to the foam layer 10 through a vacuum hot pressing process to avoid air bubble residue.

[0065] In process S1, the foam layer 10 is made of polyurethane foam.

[0066] In process S3, the airbag material sealing layer 20 is made of materials including nylon fabric, polyamide fabric, polyurethane, polyamide 66, and PET polyester, and the thickness of the airbag material sealing layer 20 is 0.5-2mm.

[0067] In process S4, the thermal conductive medium 30 is deionized water or silicone gel, and the filling rate of the thermal conductive medium 30 is ≥95%.

[0068] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0069] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
