Abstract
Description
Technical Field
[0001] This invention relates to a mattress, and more specifically, to a heated mattress structure, and also to a heated and washable mattress structure. Background Technology
[0002] Currently, the mainstream heating methods for heated mattresses fall into two categories: electric heating wire heating and water circulation heating. Compared to electric heating wire heating, water circulation heating provides more even heat distribution and a gentler temperature, making it a more comfortable technology. In existing water circulation heated mattress solutions, the working principle is as follows: water is used as the heat transfer medium. First, the water is heated to a preset temperature by electric heating wires. Then, a circulation pump drives the hot water to circulate through the internal pipes of the mattress, thereby achieving overall mattress heating.
[0003] However, current water heating solutions have certain drawbacks: the circulating pump generates vibration noise during operation, and users are more sensitive to environmental noise when they are falling asleep. This kind of noise can easily disturb users' normal rest and reduce the user experience.
[0004] Therefore, a new solution is needed to address the problem of heating mattresses using water as the heat transfer medium. Summary of the Invention
[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a heated and washable mattress structure.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a heatable mattress structure, comprising a spring core and a comfort layer, wherein the comfort layer is laid on the upper layer of the spring core, and a plurality of heating tubes are arranged on the upper side of the comfort layer along the width of the mattress; the spring core comprises a bottom core and a top core, wherein a plurality of springs are installed between the bottom core and the top core, and an elastic bladder is installed between the bottom core and the top core; the upper and lower sides of the elastic bladder are respectively connected to the top core and the bottom core; the elastic bladder is connected to a lower connecting pipe and an upper connecting pipe, and both the lower connecting pipe and the upper connecting pipe are equipped with one-way valves, which can control the one-way flow of hot water along the lower connecting pipe, the elastic bladder, and the upper connecting pipe; the lower connecting pipe is connected to the circulation output end of the heating water tank, the inlet end of the heating tube is connected to the upper connecting pipe, and the outlet end of the heating tube is connected to the circulation return end of the heating water tank.
[0007] The present invention is further configured such that the heating tube is divided into several independent first heating tubes and second heating tubes, the first heating tubes and second heating tubes are distributed at intervals, and the water in the first heating tubes and second heating tubes flows in opposite directions.
[0008] The invention is further configured such that the water in the first heating tube flows from the left side to the right side of the mattress, and the water in the second heating tube flows from the right side to the left side of the mattress; both the first heating tube and the second heating tube cover more than 80% of the width of the mattress.
[0009] The present invention is further configured to include a heating water tank, an outlet water collection pipe, and an inlet water collection pipe, wherein the outlet end of each heating pipe is connected to the outlet water collection pipe, and the outlet water collection pipe is connected to the circulation return end of the heating water tank through an outlet water diversion pipe.
[0010] The present invention is further configured such that each heating tube has a water inlet pipe and at least three sets of elastic bladders at its lower part. The water inlet pipe is located on the lower inner side of the spring core, and the elastic bladders are arranged along the width of the mattress and connected in parallel between the water inlet pipe and the water inlet end of the heating tube.
[0011] The present invention is further configured such that the ends of each heating tube are connected to the water inlet manifold.
[0012] The present invention is further configured such that the elastic bladder connected to the water inlet end of the first heating tube is located inside the spring bed core on the left side, and the elastic bladder connected to the water inlet end of the second heating tube is located inside the spring bed core on the right side.
[0013] The invention is further configured such that when the spring bed core is compressed, the elastic bladder is squeezed, and the hot water inside the elastic bladder is squeezed out and flows along the elastic bladder, the upper connecting pipe and the heating pipe to heat the comfort layer; when the spring bed core rebounds, the upper and lower ends of the elastic bladder are pulled, and the hot water in the heating water tank can be drawn into the elastic bladder as a supplement to the heating hot water.
[0014] The present invention also provides a heated and washable mattress structure, including the heated mattress structure as described above, and a surface pad, which is disposed on the upper side of the comfort layer and is removable.
[0015] The invention is further configured such that a bed cover is integrally sewn to the outer periphery of the surface pad, and the bed cover surrounds the outer periphery of the mattress, which can house the comfort layer and the spring core cover inside.
[0016] In summary, the present invention has the following beneficial effects:
[0017] In this design, heating elements are installed on the upper layer of the mattress, with hot water circulating inside. This heats the mattress. Furthermore, elastic springs are installed inside the mattress core. These springs, combined with the body's movements during sleep (such as turning over), propel the hot water within the heating elements. The hot water flows along the elastic springs, the upper connecting pipe, and the heating elements, heating the comfort layer. When the spring core rebounds, the upper and lower ends of the elastic springs are stretched, drawing hot water from the heating tank into the elastic springs to supplement the heating water supply.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0028] Example 1
[0029] This embodiment discloses a structure for a heatable mattress, referring to... Figure 1 , Figure 2 As shown, the mattress includes a spring core 1 and a comfort layer 2. The spring core 1 serves as the main support structure of the mattress. The spring core 1 includes a bottom core 11 and an upper core 12. Several springs 3 are installed between the bottom core 11 and the upper core 12.
[0030] Comfort layer 2 is laid on top of spring core 1. Comfort layer 2 has a certain thickness. Specifically, sponge or latex can be used as the main support material of comfort layer 2, or a combination of materials can be used.
[0031] Several heating tubes 5 are arranged along the width of the mattress on the upper side of the comfort layer 2. Each heating tube 5 is a parallel and independent structure, rather than the continuous serpentine tube structure of the prior art. The two ends of each heating tube 5 are a water inlet 51 and a water outlet 52, located roughly on both sides of the mattress. During heating, hot water flows along the width of the mattress, entering from the water inlet 51 on one side of the heating tube 5, passing through both sides of the mattress, and finally exiting from the water outlet 52 on the other side. The heated hot water flows along the width of the mattress, thus heating it.
[0032] Reference Figure 2 , Figure 3 As shown, an elastic bladder 4 is installed between the bottom layer 11 and the top layer 12 of the bed core. The elastic bladder 4 can be a rubber bladder structure that can produce elastic deformation. The upper and lower sides of the elastic bladder 4 are connected to the top layer 12 and the bottom layer 11 of the bed core, respectively. Specifically, the upper side of the elastic bladder 4 can be bonded to the top layer 12 of the bed core, and the lower side of the elastic bladder 4 can be bonded to the bottom layer 11 of the bed core.
[0033] When the spring core 1 is subjected to elastic compression and elastic recovery, it can exert corresponding compression and relaxation on the elastic bladder 4, thereby causing the elastic bladder 4 to undergo corresponding elastic deformation. The elastic bladder 4 can hold heated hot water. During compression, the hot water inside the elastic bladder 4 can be squeezed out towards the heating pipe 5; during elastic relaxation and recovery, some water from the heating water tank 9 can be drawn into the elastic bladder 4, thus replenishing the hot water inside the elastic bladder 4.
[0034] Reference Figure 4 As shown, the elastic bladder 4 is connected to a lower connecting pipe 41 and an upper connecting pipe 42, both of which are equipped with one-way valves 43. The one-way valves 43 control the flow of hot water into and out of the elastic bladder 4. The one-way valves 43 operate in the same direction, controlling the unidirectional flow of hot water along the lower connecting pipe 41, the elastic bladder 4, and the upper connecting pipe 42. When the elastic bladder 4 is compressed, the hot water inside needs to be discharged. The one-way valve 43 on the upper connecting pipe 42 is opened, while the one-way valve 43 on the lower connecting pipe 41 is closed, allowing hot water to be transported from the upper connecting pipe 42 to the heating pipe 5.
[0035] When the elastic bladder 4 is elastically expanded, a relative negative pressure is generated inside the elastic bladder 4. The one-way valve 43 of the lower connecting pipe 41 can be opened, and the one-way valve 43 of the upper connecting pipe 42 can be shut off. Hot water will be drawn from the lower connecting pipe 41 into the elastic bladder 4 as a supplement to the hot water.
[0036] Reference Figure 7 As shown, the mattress in this embodiment also includes a heating water tank 9. The heating water tank 9 contains water as a heat transfer medium, and an electric heating element can heat and maintain the water within a preset temperature range. The heating water tank 9 has a circulation output end 91 and a circulation return end 92. The circulation output end 91 is the output end for heated hot water, and the circulation return end 92 is the return end for the heated, cooled water from the heating tube 5. The lower connecting pipe 41 connects to the circulation output end 91 of the heating water tank 9, the inlet end 51 of the heating tube 5 connects to the upper connecting pipe 42, and the outlet end 52 of the heating tube 5 connects to the circulation return end 92 of the heating water tank 9.
[0037] A circulation pump 10 is installed at the circulation output end 91 of the heating water tank 9. The circulation pump 10 provides the power to pump hot water, thereby pumping hot water to form a circulation between the heating water tank 9 and the heating pipe 5, which can heat the mattress. During the hot water circulation process, the circulation pump 10 can act as an active circulation drive.
[0038] During operation, the circulation pump 10 generates some noise. In normal mode, the circulation pump 10 operates normally and can circulate hot water normally. In deep sleep mode, the operating power of the circulation pump 10 can be appropriately reduced, thereby reducing the operating noise of the circulation pump 10. Combined with the body's turning over and other movements during sleep as the driving force, and with the compression and recovery of the elastic bladder 4, the hot water in the heating tube 5 in the mattress can be circulated. Alternatively, the circulation pump 10 can be completely stopped, and only the compression and recovery of the elastic bladder 4 is used as the power for hot water circulation.
[0039] During the passive operation of the elastic bladder 4, when the spring bed core 1 is compressed, the pressure inside the elastic bladder 4 increases, and the hot water inside needs to be squeezed out and flows along the elastic bladder 4, the upper connecting pipe 42 and the heating pipe 5 to heat the comfort layer 2; when the spring bed core 1 elastically rebounds, the upper and lower ends of the elastic bladder 4 are pulled, and the hot water in the heating water tank 9 can be drawn into the elastic bladder 4 as a supplement to the heating hot water.
[0040] Reference Figure 7 As shown, the mattress in this embodiment also includes a water outlet manifold 7 and a water inlet manifold 8. The water outlet end 52 of each heating tube 5 is connected to the water outlet manifold 7, and the water outlet manifold 7 is connected to the circulation return end 92 of the heating water tank 9 through a water outlet drain pipe 71. The water outlet manifold 7 and the water outlet drain pipe 71 can serve as a collection and circulation channel for cold water, allowing it to flow back to the circulation return end 92.
[0041] Each heating element 5 has a water inlet pipe 6 at its lower part, through which water is supplied to the corresponding heating element 5. Hot water is output from the heating element 5, passes through the corresponding elastic bladder 4, and then enters the corresponding heating element 5 to heat the mattress.
[0042] Reference Figure 2 , Figure 3 As shown, the water inlet pipe 6 is located on the lower inner side of the spring core 1, and the ends of each heating tube 5 are interconnected with the water inlet manifold 8. Furthermore, several elastic pockets 4 are installed at the water inlet end 51 of each heating tube 5, typically 3-6. The elastic pockets 4 are arranged along the width of the mattress and connected in parallel between the water inlet pipe 6 and the water inlet end 51 of the heating tube 5, resulting in a uniform distribution of elastic pockets 4 along the width of the mattress. This allows the body to adaptively compress and drive the corresponding elastic pockets when lying down.
[0043] Furthermore, referring to Figure 1 , Figure 2 , Figure 5 As shown, the heating element 5 is divided into several independent first heating elements 501 and second heating elements 502, which are distributed alternately. The water in the first heating elements 501 and second heating elements 502 flows in opposite directions: the water in the first heating element 501 flows from the left side 100 to the right side 200 of the mattress, and the water in the second heating element 50 flows from the right side 200 to the left side 100 of the mattress.
[0044] Moreover, the first heating element 501 and the second heating element 502 both cover more than 80% of the width of the mattress, so that when hot water flows in the width direction, it can evenly heat the mattress in the width direction, and the heated area can cover most of the mattress surface.
[0045] Reference Figure 2, Figure 3 , Figure 5 , Figure 6 As shown, in this embodiment, the elastic bladder 4 connected to the water inlet end 51 of the first heating tube 501 is located inside the spring bed core 1 of the left side 100, and the elastic bladder 4 connected to the water inlet end 51 of the second heating tube 502 is located inside the spring bed core 1 of the right side 200.
[0046] The structure in this embodiment is particularly suitable for double bed mattresses. Several elastic bladders 4 are arranged in the left side 100 of the mattress, which can drive the hot water in the first heating tube 501. Several elastic bladders 4 are arranged in the right side 200 of the mattress, which can drive the hot water in the second heating tube 502.
[0047] During use, two people lie on the surface of the left side 100 and right side 200 of the mattress respectively. Any turning over or related movement on the left side 100 and right side 200 will apply a squeezing action to the elastic bladder 4 on the corresponding side, thereby driving the circulation of heated water.
[0048] Furthermore, by distributing the elastic pockets 4 on the left side 100 and right side 200 of the mattress, the pressure from movements on both sides can be collected. When there is a rolling movement on either side of the left side 100 or right side 200, hot water can be circulated through the corresponding heating tube 5. Moreover, when movement occurs on only one side of the mattress (left side 100 or right side 200), only half the number of heating tubes 5 are used for hot water circulation, reducing the force required to drive the hot water and making it easier for rolling movements to circulate the hot water within the heating tubes 5.
[0049] During the hot water circulation process, the hot water in the first heating tube 501 is input from the inlet end 51 on the left, flows through the middle section of the first heating tube 501, and is output from the outlet end 52 on the left. It then flows from the outlet end 52 to the outlet collection pipe 7, thus realizing the circulation of hot water. The flow direction of the hot water in the first heating tube 501 is from right to left, forming a roughly opposite flow, which can also heat the surface of the mattress.
[0050] In addition, to improve the relative flatness of the surface of the comfort layer 2, several upper grooves 21 are formed on the upper side of the comfort layer 2. The shape of the upper grooves 21 is adapted to the heating tube 5, which can restrict and accommodate the heating tube 5, so that the heating tube 5 can be arranged smoothly. Moreover, several lower grooves 22 are also formed on the lower side of the comfort layer 2, which can accommodate the transition sections and bends at both ends of the heating tube 5.
[0051] When movement occurs on one side of the mattress (left side 100 or right side 200), if the amount of movement is small, the hot water delivery volume in heating tube 501 is small, and the hot water flow within heating tube 5 may only be about 50cm. At this time, it is impossible to form a complete flow in the upper middle section of heating tube 5. Taking the first heating tube 501 as an example, when a small amount of flow occurs in the first heating tube 501 (the flow volume is approximately 50cm), the first heating tube 501 will first heat the left side 100 of the mattress, which can concentrate the heat on one side, so that the corresponding left and right sides can be slightly heated.
[0052] Furthermore, in this solution, the heating tubes are arranged along the width of the mattress, and each heating tube is circulated with water. Compared to the traditional continuous serpentine arrangement of heating tubes, the length of a single heating tube in this embodiment can be shortened. This is particularly suitable for situations where there is a small flow rate driven by pressure from the movement of the human body, such as turning over. Even when there is a small flow rate, such as 30-50cm of the length of heating tube 5, although a circulation cannot be formed, some heat can still be transferred to the surface of the corresponding side of the mattress, thus heating the surface of the corresponding side of the mattress.
[0053] When the hot water flow rate is large, the hot water can be effectively circulated and driven, which can quickly and effectively heat each heating element 5.
[0054] In this embodiment, the heating tubes 5 are arranged in a parallel pattern on the surface of the comfort layer 2 of the mattress. When a person on one side experiences a squeezing motion, the hot water in the heating tubes 5 can circulate along the width of the mattress, thereby providing appropriate heating to the left side 100 and the right side 200 of the mattress. That is, the solution in this embodiment can heat both sides of the mattress when a person moves on either side, avoiding excessive temperature differences between the left and right sides. Especially when there is a large weight difference between the left and right sides, if the hot water circulation is controlled on only one side, it is easy to cause a large heating circulation on the side with a larger weight and a small heating circulation on the side with a smaller weight.
[0055] In addition, since tubular components such as the elastic bladder are located inside the spring core, an insulating layer can be laminated onto the surface of the inner cavity of the spring core to improve its heat retention, thereby reducing heat dissipation and heat loss of the entire system.
[0056] Example 2
[0057] Reference Figure 8As shown, this embodiment also discloses a heated and washable mattress structure, which includes the heated mattress structure as described above; based on the heated mattress structure described above, it also includes a surface pad 300, which is disposed on the upper side of the comfort layer 2 and is removable.
[0058] Specifically, a bed cover 301 is integrally sewn to the outer periphery of the surface pad 300. The bed cover 301 surrounds the outer periphery of the mattress and can enclose the comfort layer 2 and the spring core 1. The connection between the bed cover 301 and the outer periphery of the mattress can be installed using a zipper or a snap-on structure to facilitate the disassembly and cleaning of the surface pad 300 and the bed cover 301.
[0059] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
