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

[0004] Low refrigeration efficiency: The heat-conducting water pipes generally adopt a pipeline layout with a spiral or serpentine distribution. The pipeline layout only forms a linear cold source, and the contact area between the pipeline and the mattress is small. It is necessary to rely on lower water temperature and higher power to maintain the refrigeration effect, resulting in high energy consumption and large noise of the main unit.

[0005] Condensed water problem: The low-temperature pipeline is exposed to the air and directly contacts the air to generate condensed water, resulting in the mattress being damp and prone to mildew, affecting normal use.

[0006] Uneven temperature distribution: The heat and cold are concentrated near the pipeline, and the local heat and cold difference is obvious, affecting the user experience.

[0007] Therefore, there are still disadvantages and deficiencies in the prior art. How to provide a water-cooled and heated mattress without condensed water and a processing method thereof is a technical problem that those skilled in the art urgently need to solve. Summary of the Invention

[0023] Wherein, the water inlet end of the circulating water pipe is one end of the first main channel / the second main channel, and the water outlet end of the circulating water pipe is one end of the second main channel / the first main channel.

[0024] The present invention also provides a processing method for a water-cooling and heating mattress without condensed water, including the following processes:

[0025] S1. Select a foaming layer with an open cell rate ≥ 50% as the mattress matrix, and open channels on the surface of the foaming layer;

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0040] In order to enable those skilled in the art of this technology to better understand the solution of the present invention, the present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0041] The present invention provides a water-cooled and heated mattress without condensed water, adopts a composite heat conduction structure, converts a linear cold source into a planar heat exchange, improves the cold and heat diffusion efficiency, can reduce the energy consumption and noise of the water-cooled and heated main unit 50, and eliminates condensed water.

[0042] Please refer to Figures 1 to 3 The water-cooled and heated mattress without condensation water provided by the present invention comprises a foam layer 10 with an opening rate of ≥50%, a groove 11 is provided on the surface of the foam layer 10; an airbag material sealing layer 20 wrapping the foam layer 10, a liquid or gel-state heat-conducting medium 30 filled in the airbag material sealing layer 20, and a circulating water pipe 40 embedded in the groove 11 and in close contact with the foam layer 10. Among them, the circulating water pipe 40 is wrapped by the heat-conducting medium 30.

[0043] The open porosity referred to herein refers to the proportion of interconnected pores per unit volume or unit area in the foaming layer 10; specifically, it reflects the ratio of the number or volume of open pores in the foaming layer 10 to the total volume or total area.

[0044] The water-cooled and heated mattress adopts a composite heat conduction structure, a high-opening-rate foam layer 10, an embedded circulating water pipe 40 and a coordinated design of a heat-conducting medium 30, which converts a linear cold source into a planar heat exchange, uniformly distributes the temperature, improves the efficiency of heat and cold diffusion, and improves the user experience. Since the circulating water pipe 40 is completely embedded in the foam layer 10 and wrapped by the heat-conducting medium 30, the circulating water pipe 40 is isolated from the outside air, so there is no condensation caused by temperature difference, and condensed water is eliminated, so that the mattress will not be easily moldy due to moisture and can be used for a long time.

[0045] In cooling mode, cold water circulates in the circulating water pipe 40, and the cold energy is transferred to the surrounding foam layer 10 and the heat-conducting medium 30 through the pipe wall of the circulating water pipe 40. The heat-conducting medium 30 evenly spreads the cold energy to the entire mattress surface through its fluidity, so that the temperature at each location is basically consistent;

[0046] In heating mode, hot water circulates in the circulating water pipe 40, and the heat is transferred to the surrounding foam layer 10 and the heat-conducting medium 30 through the pipe wall of the circulating water pipe 40. The heat-conducting medium 30 diffuses the heat evenly to the entire mattress surface through its fluidity to avoid local overheating.

[0047] Specifically, the foam layer 10 is used as the mattress base, and polyurethane sponge can be used. The total length of the channel 11 is 40-60 meters, which can be set according to actual needs.

[0048] The circulating water pipe 40 is embedded in the groove 11 and fixed by heat sealing, snapping or adhesive to ensure that the pipe is in close contact with the foaming layer 10. The circulating water pipe 40 is a hose containing materials such as silicone\PVC\graphene composite PVC, graphene composite silicone, etc.

[0049] The airbag material sealing layer 20 includes fabric nylon, polyamide fabric, polyurethane (TPU), polyamide 66, PET polyester or other composite materials. The thickness of the airbag material sealing layer 20 is 0.5 - 2 mm. The upper and lower surfaces of the foaming layer 10 are completely sealed by the airbag material sealing layer 20, and only a water inlet and a water outlet are reserved at one end for the water inlet end and the water outlet end of the circulating water pipe 40 to penetrate in and out.

[0050] After the airbag material sealing layer 20 wraps the foaming 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 foaming layer 10.

[0051] Preferably, in this embodiment, the filling rate of the heat-conducting medium 30 ≥ 95%. With such a setting, the filling degree of the heat-conducting medium 30 is relatively high, and the heat-conducting medium 30 can fully wrap the pipes and the pores of the foaming layer 10 to ensure the heat-conducting effect.

[0052] Preferably, in this embodiment, the heat-conducting medium 30 is deionized water or silicone-based gel, and the heat-conducting effect is better. That is, the above-mentioned liquid heat-conducting medium 30 is deionized water, and the gel-state heat-conducting medium 30 is silicone-based gel.

[0053] Preferably, in this embodiment, the foaming layer 10 and the airbag material sealing layer 20 are bonded by vacuum hot pressing to avoid air bubble residues.

[0054] Please refer to Figures 1 to 3 , the water-cooled and heated mattress without condensed water provided by the present invention further includes a water-cooled and heated main unit 50 communicated with the water inlet end and the water outlet end of the circulating water pipe 40. The water-cooled and heated main unit 50 is the core control device of the water-cooled and heated mattress, which can heat and cool the water in the water tank inside the main unit, and the built-in water pump can transport cold water or hot water into the mattress, and adjust the temperature of the mattress by heating or cooling the circulating water, with both heating and cooling functions to achieve intelligent temperature control.

[0055] Please refer to Figures 1 to 3 , the channel 11 includes a first main channel 111, a second main channel 112, a first sub-channel 113 and a second sub-channel 114.

[0056] Both ends of the first sub-channel 113 are respectively communicated with the first main channel 111 and the second main channel 112; both ends of the second sub-channel 114 are respectively communicated with the first main channel 111 and the second main channel 112.

[0057] Among them, the water inlet end of the circulating water pipe 40 is one end of the first main channel 111 / the second main channel 112, and the water outlet end of the circulating water pipe 40 is one end of the second main channel 112 / the first main channel 111.

[0058] The first sub-channel 113 and the second sub-channel 114 are roughly serpentine. Since the shape of the circulating water pipe 40 is compatible with the shape of the groove 11, such an arrangement can increase the contact area between the circulating water pipe 40 and the foaming layer 10 and improve the heat conduction efficiency.

[0059] 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 close to the circulating water pipe 40 to the side in contact with the human body.

[0060] With such a configuration, the heat exchange efficiency between the heat-conducting medium 30 and the pipeline is enhanced through the high-opening area, and the excessive heat transfer to the human body is reduced through the low-opening area, thereby avoiding cold and hot stimulation, achieving dynamic temperature buffering, and improving body comfort.

[0061] Optionally, a diverter valve is added to the circulating water pipe 40, and the diverter valve is used to dynamically adjust the water flow path according to the water temperature and the user pressure distribution.

[0062] With this arrangement, when the user lies down, the branch flow in the pressure area can be automatically increased to avoid local temperature unevenness.

[0063] Optionally, a flexible optical fiber sensor array is embedded in the foaming layer 10 to monitor the user's body surface temperature, humidity and pressure distribution in real time, and provide feedback through an APP.

[0064] This setting can automatically adjust the water temperature and flow rate to prevent local frostbite or high temperature burns. The data can be linked to smart home systems (such as air conditioners, humidifiers, etc.) to achieve global optimization of the sleeping environment.

[0065] When in use, in cooling mode, the cold water output by the water-cooling and heating main unit 50 circulates in the circulating water pipe 40, and the cold energy is transferred to the surrounding foam layer 10 and the heat-conducting medium 30 through the pipe wall of the circulating water pipe 40. The heat-conducting medium 30 evenly spreads the cold energy to the entire mattress surface through its fluidity, so that the temperature at all locations is basically consistent;

[0066] In the heating mode, the hot water output by the water cooling and heating main unit 50 circulates in the circulating water pipe 40, and the heat is transferred to the surrounding foam layer 10 and the heat conducting medium 30 through the pipe wall of the circulating water pipe 40. The heat conducting medium 30 diffuses the heat evenly to the entire mattress surface through its fluidity to avoid local overheating.

[0067] The water-cooling and heating mattress without condensed water provided by the present invention adopts a composite heat conduction structure, and the collaborative design of the foaming layer 10 with a high open-cell rate, the embedded circulating water pipe 40 and the heat conduction medium 30 converts the linear cold source into a planar heat exchange, improving the cold and heat diffusion efficiency; due to the good heat conduction effect of the water-cooling and heating mattress, the cold quantity demand of the water-cooling and heating main unit 50 can be reduced, and the energy consumption and noise are reduced. Since the circulating water pipe 40 is completely embedded in the foaming layer 10 and wrapped by the heat conduction medium 30, the circulating water pipe 40 is isolated from the external air, so there is no condensation phenomenon caused by temperature difference, and the condensed water is eliminated. Therefore, the mattress is not prone to mildew due to moisture and can be used for a long time.

[0068] Actual tests show that when using the water-cooling and heating mattress without condensed water provided by the present invention, under the same cooling capacity, the surface temperature uniformity of the mattress is increased by 60%, and the power consumption of the water-cooling and heating main unit 50 is reduced by 40%; no condensed water is generated after continuous operation for 8 hours, and the humidity of the mattress is maintained at ≤50%.

[0069] In addition to the water-cooling and heating mattress without condensed water disclosed in each of the above embodiments, the present invention also provides a processing method for the water-cooling and heating mattress without condensed water, including the following processes:

[0070] S1. Select a foaming layer 10 with an open-cell rate ≥50% as the mattress base, and open a channel 11 on the surface of the foaming layer 10;

[0071] S2. Embed the circulating water pipe 40 into the channel 11 of the foaming layer 10, and fix it by heat sealing, buckling or adhesive to ensure that the circulating water pipe 40 is in close contact with the foaming layer 10;

[0072] S3. Use the airbag material sealing layer 20 to completely seal the upper and lower surfaces of the foaming layer 10;

[0073] S4. Inject a liquid or gel-like heat conduction 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 conduction medium 30;

[0074] S5. Make the airbag material sealing layer 20 fit with the foaming layer 10 through a vacuum hot pressing process to avoid air bubble residues.

[0075] Among them, in process S1, the foaming layer 10 is made of polyurethane sponge.

[0076] In process S3, the material of the airbag material sealing layer 20 includes fabric nylon, polyamide fabric, polyurethane, polyamide 66, PET polyester, and the thickness of the airbag material sealing layer 20 is 0.5 - 2 mm.

[0077] In process S4, the heat conduction medium 30 is deionized water or silicone-based gel, and the filling rate of the heat conduction medium 30 is ≥95%.

[0078] It should be noted that in this specification, relational terms such as first and second are only used to distinguish one entity from several other entities, and do not necessarily require or imply any actual relationship or order between these entities.

[0079] In this article, specific examples are used to elaborate on the principles and implementation manners of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the protection scope of the present invention.
