Description

Cold Blanket {COOLING AND WARMING BLANKET}

The present invention relates to a blanket. Specifically, it relates to cold and warm blankets.

Today, as technology advances, the proportion of using supplements (such as cold and hot blankets, essentially oil pumps and air purifiers) to increase the quality of human life is increasing. In other words, it was important for different manufacturers to develop ways to augment and optimize the effectiveness of conventional auxiliary products to meet the different needs of users.

Taiwan Utility Model Registration No. M288532 (published on October 14, 2005) entitled “Structure of Cold and Warm Blanket” is known from the inventor.

As shown in FIG. 1, the present configuration includes a blanket 11 having a face provided with a wound long pipe 12. The pipe 12 has a first end used as an inlet and a second end used as an outlet, and the inlet and outlet are formed at the side ends of the blanket 11. The pipe 112 comprises an outer circumference with a flat outer circumferential surface 124 corresponding to the surface of the blanket 11.

The pipe 12 has an inner circumference formed with ribs 125 opposite the flat outer circumferential surface 124. The cover member 13 is further provided on the surface of the blanket 12 provided with the pipe 12 (like a sponge) which forms the plane of a cold / hot blanket. In addition, an inlet joint 14 and an outlet joint 15 are provided at the inlet and outlet of the pipe 12. Thus, the liquid (such as cold water and hot water) is first input to the pipe 12 through the inlet joint 14 and then output from the pipe 12 through the outlet joint 15 so that the liquid is cooled down (not shown). Back) to evenly distribute the cold / hot temperatures of the surface of the blanket 11.

On hot summer nights, the cold blankets allow the user to sleep comfortably. It warms users in cold winters. Thus, cold blankets are very popular.

However, cold blankets have several disadvantages, such as:

1. Complex structure of cold and hot blanket

Referring to FIG. 1, the structure of a cold blanket includes a blanket 11, a pipe 12, and a cover member 13, the blanket 11 being made of latex fibers and polyvinyl chloride (PVC), The pipe 12 is a blandable soft pipe and the cover member is a sponge. Thus, cold blankets use several materials. Moreover, the pipe 12 must provide a rib 125 formed in the inner circumference opposite the flat outer circumferential surface 124, so that if the user is on the blanket 11, the pipe may not be pressed so that the fluid may You can stop the flow through. In order to perform the above function, the pipe 12 needs to be treated in a predetermined shape before the cold blanket is manufactured, thereby increasing the manufacturing process of the cold blanket, thereby increasing the cost.

2. Many manufacturing processes of cold and hot blanket

Referring to FIG. 1, the structure of the cold blanket includes three layers, namely the blanket 11, the pipe 12, and the cover member 13. When manufacturing the cold and hot blankets, the worker must first bend the pipe and install this pipe 12 on the surface of the blanket 11. Thereafter, the worker covers the pipe 12 so that the cover member 13 forms a plane of the blanket 11 in which the pipe 12 is installed. However, in the above-described process, the relevant manufacturer has to finish it manually because it is difficult to automatically finish this process. As a result, cold blankets have an extremely low manufacturing efficiency and many processes limit the production of cold blankets, adversely affecting product quality.

3. Excessive thickness of cold and hot blanket

Referring to FIG. 1, the structure of the cold blanket directs liquid to the pipe 12 to maintain the surface temperature of the blanket 11. Moreover, the cover member 13 is used to cover the pipe 12 in order to increase the softness and elasticity of the cold blanket. In order to perform the above functions of cold and hot blankets, the relevant manufacturers cannot reduce the overall thickness and therefore require a large amount of space, which causes problems in transporting it.

Moreover, in addition to the difficulty of storing the cold blanket, it is inconvenient for the user to carry the blanket. As a result. It has become important for related manufacturers to develop cold blankets with simple processes and simple structures to substantially improve manufacturing efficiency.

The present inventors have attempted to develop a cold blanket to solve the existing problem of the cold blanket to improve the manufacturing efficiency.

A primary object of the present invention is to provide a cold and hot blanket in which the upper member and the lower member are coupled to the blanket by high frequency sealing. The blanket comprises a liquid inlet zone and a liquid outlet zone, with an inlet joint on the side of the liquid inlet zone and an outlet joint on the side of the liquid outlet zone.

The inlet joint is used to guide the liquid entering the liquid inlet zone (such as cold and hot water) from an external source, while the outlet joint is used to guide the liquid in the liquid outlet zone to the external source. A first channel is formed between each end of the liquid inlet region and the liquid outlet region, opposite the side end having an inlet joint and an outlet joint to guide the liquid inlet region to the liquid outlet region.

Moreover, the plurality of air chambers are uniformly provided in the liquid inlet and outlet regions. The second channel is formed between two adjacent air channels such that liquid flowing into the fluid inlet and outlet regions can be uniformly guided across the fluid inlet and outlet regions via the second channel.

Thus, the user can obtain the desired temperature uniformly generated on the surface of the upper material of the blanket by guiding the liquid (such as cold water and hot water) to flow through the first and second channels. As a result, the structure of the cold blanket of the present invention can be simplified and the manufacturing cost can be substantially lowered. On the other hand, the surface of the upper material of the blanket can generate and maintain the cold temperature uniformly.

A second object of the present invention is to provide a cold blanket, wherein the upper material and the lower material are thin sheets, and all these sheets are joined to the blanket by high frequency sealing to divide the blanket into a fluid inlet zone and a fluid outlet zone. . The liquid inlet and outlet areas are provided with a plurality of air chambers. As a result, the process of the cold blanket of the present invention can be simplified by using a fully automatic machine, so that the production of the cold blanket automatically can be substantially increased.

A third object of the present invention is to provide a cold blanket which is entirely made of a plastic material and whose total volume is compact, which is easy to transport and store in the storage compartment. Moreover, the user can easily fold the cold blanket, and it is easy to carry the cold blanket of the present invention on the upper side, thereby increasing the practical ability.

By using the blanket of the present invention, the structure is simple and easy to transport and store, and the manufacturing process of the blanky is fully automated, which facilitates mass production.

2, a cold blanket according to a preferred embodiment of the present invention is illustrated. As shown, the cold blanket comprises a blanket 2, which comprises a liquid inlet region 21 and a liquid outlet region 22. An inlet joint 211 is provided on the side of the liquid inlet region 2, and an outlet joint 211 is provided on the side end of the liquid outlet region 22. On the other hand, it is formed opposite the side end having the inflow joint 211 and the outflow joint 221 between each side end of the liquid inflow area 21 and the liquid outflow area 22 of the first channel 24. The inlet joint 211 is used to guide the liquid (such as cold water and hot water) that has flowed out of the external source into the liquid inlet area 21. The first channel 24 is used to guide the fluid in the liquid inlet region 21 to the liquid outlet region 22. Outlet joint 221 is used to guide the liquid in liquid outlet region 22 to an external circle.

In addition, a plurality of air chambers 3 are uniformly provided in the liquid inlet region 21 and the liquid outlet region 22. The second chamber 26 is formed between each two adjacent air chambers 3 such that liquid flowing in the liquid inlet and liquid outlet regions 21, 22 flows in and out of the liquid via the second chamber 26. It is possible to guide uniformly through the areas 21 and 22. Accordingly, the blanket 2 generates and maintains a uniform cold / hot temperature based on the liquid temperature flowing in the liquid inflow and outflow regions 21, 22.

Referring again to FIG. 2, in a preferred embodiment of the present invention, the blanket 2 is also connected to a heat exchanger (not shown), which heat exchanger is used to provide the liquid of the desired temperature required by the user. . When liquid flows from the inlet joint 211 to the liquid inlet region 21, the liquid flows through the second chamber 26 of the liquid inlet region 21 (along the arrow direction).

Since the second channels 26 of the liquid inlet zone 2 communicate with each other, the liquid flows evenly through the liquid inlet zone 2, so that this liquid temperature is transmitted to the surface of the blanket 2 of the liquid inlet zone 21. Distribute evenly to

The liquid then flows through the first channel 24 to the second channel 26 of the liquid outlet region 22. Since the second channels 26 of the liquid outlet region 22 are in communication with each other, the liquid flows evenly through the liquid outlet region 22 so that the liquid temperature is uniform on the surface of the blanket 2 of the liquid outlet region 22. Is distributed. Finally, the liquid again flows back through the outlet joint 211 to the heat exchanger, and then heat exchange takes place in the heat exchanger to heat or cool the liquid to raise and lower the liquid temperature to maintain the desired temperature required by the user. .

Thereafter, the liquid is again guided from the inlet joint 211 to the liquid inlet region 21 to perform the next cold / hot circulation. As a result, the blanket 2 can generate the desired temperature required by the user to keep the temperature useful.

2 and 3, the blanket 21 comprises an upper material 28 and a lower material 29, which are thin sheets of plastic material. Each thin sheet comprises a cover layer (such as latex) 4 and an inner layer 5 (such as thermoplastic polyurethane (TPU) or polyvinyl crude (PVC)).

In a preferred embodiment of the present invention, the cover layer 4 is preferably latex fibers and the inner layer 5 is preferably PVC. However, in another preferred embodiment of the present invention, the cover layer 4 and the inner layer 5 are not limited to the above materials and may be selected from other equivalent materials. Because of the thermal melting properties of the inner layer 5, the inner layer 5 can be melted at high temperatures. Thus, the two inner layers 5 are bonded together and after the temperature is lowered, they are cured and integrated into one piece. Thus, two inner layers of upper and lower materials 28 and 29 can be joined together with high frequency sealing so that the upper and lower materials 28 and 29 can be joined to the blanket 2 and the upper and lower materials The space between 28 and 29 may be divided into a fluid inlet region 21 and a fluid outlet region 22 into the first channel 24, the second channel 26 and the air chamber 2. In conclusion, the relevant manufacturer can automatically manufacture the cold blanket of the present invention by using an automatic machine, which can efficiently improve the manufacturing efficiency of the cold blanket, and substantially reduce the manufacturing cost for mass production.

Referring again to FIGS. 2 and 3, when the user is on the blanket 2, the support function of the air chamber 3 prevents the first and second chambers 24, 25 from being pressed by the user to the inner circumference. It prevents the problem that the circle is pressed to prevent the liquid from flowing. Moreover, when the relevant manufacturer seals the two inner layers 5 with high frequency sealing, the two inner layers 5 are melted and joined to each other in the sealing part and the partial material of the two inner layers 5 is high frequency sealing. The pressing force of the mold (not shown) generates side displacement with respect to the sealing portion.

After the material has cured, support portions 51 are formed on two sides of each seal ring portion. Thus, each air chamber 3, the first channel 24 and the second channel 26 will be formed with one of the support portions 51 corresponding to the sealing portion of the inner layer 5. In conclusion, the support 51 can flow smoothly through the air chamber 3, the first chamber 24 and the second channels 24, 26.

It should be noted that the surface of the blanket 2 can be printed with a pattern and decorative design in a preferred embodiment of the present invention in order to enhance the decorative effect of the cold and hot blankets to increase the consumer's desire to purchase.

Various changes and modifications of the present embodiments may be made without departing from the spirit and scope of the present invention, which has been described in the preferred embodiments and is limited only by the appended claims.
