Description

Technical Field

[0001] This invention relates to the field of heated and cooled mattress technology, specifically a water tank module for a heated and cooled mattress main unit. Background Technology

[0002] As the core component for temperature regulation in heated and cooled mattresses, the main unit's structure directly affects the product's portability, operational stability, and energy efficiency. Current heated and cooled mattress main units generally employ a dual-tank design, such as a storage tank and a circulating tank arranged side-by-side, side-by-side, or as separate independent chambers. However, this type of dual-tank structure has the following drawbacks in practical applications: 1. The dual water tanks require a completely independent cavity separation structure, which results in a large amount of space being occupied inside the main unit, making the overall size of the main unit larger and reducing the integration of the product; 2. The dual-tank configuration requires two independent inlet / outlet water pipes and control pumps, resulting in twice the number of pipe interfaces compared to a single-tank system. This multi-interface, multi-pipe design not only increases assembly difficulty but also raises the risk of leakage at pipe connections, impacting product safety. 3. Increased complexity of the pipeline system leads to increased energy loss during the circulation process, resulting in a large amount of energy being wasted and a low product energy efficiency ratio. Summary of the Invention

[0003] To address the aforementioned shortcomings, this invention proposes a water tank module for a hot and cold mattress main unit, solving the problems of low integration and low efficiency in the water tank modules of existing hot and cold mattress main units.

[0004] To achieve this objective, the present invention adopts the following technical solution: A water tank module for a heated and cooled mattress main unit includes a water replenishment tank, a circulating water tank, and a water pump. The water replenishment tank has a water inlet and a water storage chamber. The circulating water tank is disposed in the water storage chamber of the water replenishment tank and has a water replenishment hole. The circulating water tank is connected to the water storage chamber through the water replenishment hole. The circulating water tank has a circulating inlet and a circulating outlet. The circulating outlet is connected to the water inlet of the water pump. The water outlet of the water pump is used to connect to the water inlet of the semiconductor cooling module of the heated and cooled mattress main unit. The circulating inlet is connected to the water outlet of the heated and cooled mattress.

[0005] To further clarify, the water pump is located directly below the circulating water tank.

[0006] To further explain, the water pump is vertically located below the circulating water tank, and the circulating water outlet is vertically connected to the water inlet of the water pump.

[0007] To further explain, it also includes a filter screen, which is detachably installed at the water inlet.

[0008] To further explain, a closed-loop water storage area is left between the outer periphery of the circulating water tank and the inner wall of the replenishment water tank, and both the circulating water inlet and the circulating water outlet are located at the bottom of the circulating water tank.

[0009] To further explain, the top of the water replenishment tank, the circulating water tank, and the outer periphery of the circulating water tank are integrally formed, and the vertical cross-section of the integrally formed structure is similar to a "". The circulating water tank is shaped like a "", with an installation part on the bottom surface of its outer periphery and a bottom mounting part that mates with the installation part. The bottom of the circulating water tank is sealed and installed on the bottom surface of its outer periphery.

[0010] To further explain, the water tank consists of a lid and a body with an open opening. The lid covers the open opening of the body, and the water inlet is located on the lid. The tank body, the top of the circulating water tank, and the outer circumference of the circulating water tank are integrally formed. The bottom surface of the outer circumference of the circulating water tank is provided with an installation part, and the bottom of the circulating water tank is provided with a bottom mounting part that cooperates with the installation part. The bottom of the circulating water tank is sealed and installed on the bottom surface of the outer circumference of the circulating water tank.

[0011] To further explain, the water inlet holes are provided in a plurality of manner, and the plurality of water inlet holes are respectively provided on the top and / or side of the circulating water tank.

[0012] Furthermore, it also includes a support frame located below the water supply tank, forming a receiving cavity directly below the water supply tank, the receiving cavity being used to accommodate the water pump.

[0013] To further explain, the support frame has an n-shaped structure, which consists of a horizontal top and two vertical sides. The opposite sides of the horizontal part are respectively connected to the vertical sides. The other two opposite sides of the horizontal top are respectively provided with limiting portions extending upward. The bottom of the vertical sides has horizontally extended installation portions. The installation portions are used for installation with the hot and cold mattress main unit, and the limiting portions are used for limiting the water tank.

[0014] Further explanation: It also includes an anti-overflow component, which is installed at the water inlet. When the water tank is full, the anti-overflow component blocks the water inlet.

[0015] The technical solution of the present invention may include the following beneficial effects: 1. The circulating water tank is embedded in the water storage chamber of the replenishment water tank. The double-layer design realizes the internal micro-circulation of the water tank module. The aforementioned internal micro-circulation refers to the circulation within the circulating water tank. The water returning from the heating and cooling mattress mixes with the water in the circulating water tank through the circulation inlet and then flows out from the circulation outlet, rather than the entire replenishment water tank. This effectively reduces temperature loss and accelerates the cooling speed. At the same time, although the circulating water tank and the replenishment water tank are not completely isolated, the replenishment water tank plays a role in heat preservation for the circulating water tank, further improving energy efficiency. Compared with the traditional double water tanks arranged side by side or left and right in the existing technology, or the two are separated, it is simpler and more practical. 2. Regarding improvements to water pump operation: First, the water pump is installed vertically to ensure that water completely enters the pump impeller, preventing noise caused by gas inside the pump; Second, a filter screen is installed to block external impurities (such as animal hair and bedding lint) from entering the water tank, thus avoiding affecting the operation of the water pump. 3. The closed-loop water storage area isolates the outer perimeter of the circulating water tank, effectively reducing the feeling of coldness / heat when touched from the outside, and also avoiding the phenomenon of condensation on the outer wall that would occur with a separate circulating water tank.

Detailed Implementation

[0017] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] In the description of this invention, it should be understood that the terms "length", "middle", "upper", "lower", "left", "right", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0019] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0020] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "assembly," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0021] like Figures 1-7 As shown, a water tank module for a heated and cooled mattress main unit includes a water replenishment tank 1, a circulating water tank 2, and a water pump 3. The water replenishment tank 1 has a water inlet 101 and a water storage chamber 102. The circulating water tank 2 is disposed in the water storage chamber 102 of the water replenishment tank 1. The circulating water tank 2 has a water replenishment hole 21 and is connected to the water storage chamber 102 through the water replenishment hole 21. The circulating water tank 2 has a circulating water inlet 22 and a circulating water outlet 23. The circulating water outlet 23 is connected to the water inlet of the water pump 3. The water outlet of the water pump 3 is used to connect to the water inlet of the semiconductor cooling module of the heated and cooled mattress main unit. The circulating water inlet 22 is connected to the water outlet of the heated and cooled mattress.

[0022] The water tank module proposed in this invention has a circulating water tank 2 embedded in the water storage cavity 102 of the replenishment water tank 1. The double-layer design realizes the internal micro-circulation of the water tank module. The aforementioned internal micro-circulation refers to the circulation within the circulating water tank 2. The water returning from the hot and cold mattress mixes with the water in the circulating water tank 2 through the circulation inlet 22 and then flows out from the circulation outlet 23, rather than the entire replenishment water tank 1. This effectively reduces temperature loss and accelerates the cooling speed. At the same time, although the circulating water tank 2 and the replenishment water tank 1 are not completely isolated, the replenishment water tank 1 plays a role in heat preservation for the circulating water tank 2, further improving energy efficiency. Compared with the traditional double water tanks arranged side by side or left and right in the prior art, or the two are separated, it is simpler and more practical, effectively solving the problems of low integration and low efficiency of the water tank module of the hot and cold mattress host in the prior art.

[0023] It should be noted that the water pump 3 is controlled by the electronic control module of the hot and cold mattress main unit. The electronic control module is existing technology and will not be described in detail here.

[0024] In a preferred embodiment, the water pump is located directly below the circulating water tank. This allows the water tank module to be arranged vertically, enabling the piping to be moved downwards.

[0025] In a preferred embodiment, the water pump 3 is vertically positioned below the circulating water tank 2, and the circulating water outlet 23 is vertically connected to the water inlet of the water pump 3. The vertical orientation of the water pump 3 ensures that water completely enters the impeller of the water pump 3, preventing noise caused by gas inside the water pump 3.

[0026] In another preferred embodiment, a filter screen 4 is further included, which is detachably installed on the water inlet 101. The filter screen 4 is provided to block external impurities (such as animal hair and bedding lint) from entering the water tank 1, thus avoiding affecting the operation of the water pump 3. In a specific embodiment, the filter screen 4 can be filter cotton (e.g., synthetic fiber filter cotton, non-woven filter cotton, glass fiber filter cotton, or activated carbon filter cotton), specifically, it is detachably installed on the water inlet 101 via a filter cotton frame. The detachable method can be by setting mutually mating threads, achieving threaded installation and fixation by rotation, or by using a flexible snap-fit ​​structure to achieve the detachability of the filter cotton frame.

[0027] In another preferred embodiment, a closed-loop water storage area is provided between the outer periphery of the circulating water tank 2 and the inner wall of the replenishment water tank 1. Both the circulating water inlet 22 and the circulating water outlet 23 are located at the bottom 202 of the circulating water tank 2. The closed-loop water storage area refers to the water storage area surrounding the outer periphery of the circulating water tank 2. This closed-loop water storage area isolates the outer periphery of the circulating water tank 2, effectively reducing the feeling of coldness / heat when touched from the outside, and also preventing condensation on the outer wall that would occur with a separate circulating water tank 2.

[0028] In another preferred embodiment, the top of the water replenishment tank 1 and the outer periphery of the circulating water tank 2 are integrally formed, and the vertical cross-section of the integrally formed structure is similar to a "". The circulating water tank 2 is shaped like a "", and the bottom surface of the outer periphery of the circulating water tank 2 is provided with an installation part 201. The bottom 202 of the circulating water tank 2 is provided with a bottom installation part 2021 that cooperates with the installation part 201. The bottom 202 of the circulating water tank 2 is sealed and installed on the bottom surface of the outer periphery of the circulating water tank 2.

[0029] In specific embodiments, such as Figure 6 As shown, the mounting portion 201 can be an annular groove, and the bottom mounting portion 2021 is an annular protrusion that mates with the annular groove. The annular protrusion is fitted into the annular groove and fixed with adhesive. In another embodiment, the bottom mounting portion 2021 can be an annular groove formed at the bottom 202 of the circulating water tank 2, and the corresponding mounting portion 201 is an annular protrusion that is fitted into the annular groove and fixed with adhesive.

[0030] In another preferred embodiment, the water replenishment tank 1 is divided into a tank cover 11 and a tank body 12 with an open opening. The tank cover 11 covers the open opening of the tank body 12, and the water inlet 101 is opened on the tank cover 11. The top of the tank body 12 and the circulating water tank 2 are integrally formed with the outer circumference of the circulating water tank 2. The bottom surface of the outer circumference of the circulating water tank 2 is provided with a mounting part 201, and the bottom 202 of the circulating water tank 2 is provided with a bottom mounting part 2021 that cooperates with the mounting part 201. The bottom 202 of the circulating water tank 2 is sealed and installed on the bottom surface of the outer circumference of the circulating water tank 2. The split design of the water replenishment tank 1 facilitates processing and reduces processing difficulty, while also facilitating subsequent assembly. In a specific embodiment, the tank cover 11 and the tank body 12 are fixed with adhesive.

[0031] In another specific embodiment, the outer wall of the water tank 1 is also provided with a number of mounting protrusions. The mounting protrusions are used for installation and connection with the heating and cooling mattress main unit. Specifically, the mounting protrusions are provided with threaded grooves, and screws or bolts pass through the through holes of the outer shell of the heating and cooling mattress main unit and are threadedly connected in the threaded grooves.

[0032] In another preferred embodiment, a plurality of water replenishment holes 21 are provided, and the plurality of water replenishment holes 21 are respectively provided on the top and / or side of the circulating water tank 2. The provision of a plurality of water replenishment holes 21 allows for timely replenishment of water to the circulating water tank 2. In a more preferred embodiment, the water replenishment holes 21 are located close to the circulating water outlet 23. Combined with the arrangement of the circulating water inlet 22 and the circulating water outlet 23, this reduces mutual interference between the various inflow and outflow water flows within the circulating water tank 2 and optimizes the water flow pattern within the circulating water tank 2. In a preferred embodiment, the water replenishment hole 21 is divided into round holes 211 and strip holes 212. Several round holes 211 are respectively arranged on the top of the circulating water tank 2. The round holes 211 are not located directly below the water replenishment port 101 of the water replenishment tank 1 to avoid gas entering the circulating water tank 2 during water replenishment, which would affect the operation of the water pump 3. Several strip holes 212 are respectively arranged vertically on the side of the circulating water tank 2. Both the round holes 211 and the strip holes 212 are set close to the circulating water outlet 23 to obtain a better water flow pattern.

[0033] In another preferred embodiment, a support frame 5 is further included, located below the water supply tank 1. The support frame 5 forms a receiving cavity 501 directly below the water supply tank 1, which is used to accommodate the water pump 3. The water tank module is designed as a vertically distributed module to facilitate modular installation within the heating / cooling mattress unit. Furthermore, in addition to accommodating the water pump 3, the receiving cavity 501 can also accommodate an anti-interference magnetic ring.

[0034] Preferably, the support frame 5 has an n-shaped structure, which consists of a horizontal top 51 and two vertical sides 52. The opposite sides of the horizontal part are respectively connected to the vertical sides 52. The other two opposite sides of the horizontal top 51 are respectively provided with limiting portions 511 extending upward. The bottom 202 of the vertical side 52 is provided with a horizontally extending mounting portion 521. The mounting portion 521 is used for installation with the hot and cold mattress main unit. The limiting portion 511 is used to limit the water tank 1.

[0035] The support frame 5 with the above-mentioned n-shaped structure not only forms a receiving cavity 501, but can also be used to fix the hot and cold mattress main unit and to limit the water tank 1, simplifying the internal structure of the hot and cold mattress main unit and facilitating the assembly of the water tank module.

[0036] In another preferred embodiment, an anti-overflow component 6 is further included. The anti-overflow component 6 is installed in the water inlet 101. When the water tank 1 is full, the anti-overflow component 6 seals the water inlet 101, effectively preventing water from overflowing from the water inlet 101 of the water tank 1. In a specific embodiment, the anti-overflow component 6 includes a limiting ring 61, a float 62, and a mounting bracket 63. The limiting ring 61 is installed inside the water inlet 101, and the mounting bracket 63 is installed directly below the water inlet 101. The mounting bracket 63 has a cavity for the float 62 to move up and down. The float 62 is movably placed in the cavity, and the limiting ring 61 is used to confine the float 62 within the cavity. When the float 62 rises and touches the limiting ring 61, the float 62 seals the water inlet 101. The float 62 will rise as the water level in the water tank 1 rises. By observing the rise of the float 62, users can more intuitively feel whether the water tank 1 is full and stop adding water in time.

[0037] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of the invention and should not be construed as limiting the scope of protection of the invention in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of the invention without inventive effort, and these embodiments will all fall within the scope of protection of the present invention.
