Description

Technical Field

[0001] This utility model relates to the field of water-heating blankets and is a series of applications with application number 202410125751.X and the invention title "An Integrated Constant Temperature Water-Heating Blanket." In particular, it relates to a constant temperature water-heating blanket with an integrated main unit and blanket body. Background Art

[0002] A water-heated blanket uses electricity to heat water to a constant (user-set) temperature. A water pump then circulates the hot water through a blanket lined with water pipes, thereby warming the bed. Compared to traditional electric blankets (which use internal heating wires), this method of heating prevents localized, persistent temperature increases because the heat flows through the blanket. This makes it far more comfortable and safer.

[0003] Existing water-heating blankets (such as CN2667990Y and CN114158877A) consist of a separate main unit and blanket body. The main unit for water-heating blankets, however, has already established a mature market, with models such as CN303128303S, CN214851875U, and CM218127919U. Traditionally, the main unit consists of a housing, with a water inlet connection, a water tank, a water pump, a pipe heater, and a water outlet connection connected within the housing. The water tank, which stores water, is relatively large and features a pressure relief vent on its top to release gases generated by the heated circulating water, thus preventing excessive internal pressure. During use, the main unit and blanket body are connected by a hose, and a high-lift water pump is used to transfer water from the main unit to the blanket body. For storage, the main unit must be disassembled and the water inside the blanket and main unit drained. Existing water-heating blankets are generally separate units, with few integrated units and blanket bodies forming a single structure.

[0004] The existing separated water heating blankets have the following problems: (1) The separated design of the main unit and blanket body makes the water heating blanket complex in structure, high in cost and complicated in operation. A large water tank is required to store water. As a seasonal appliance, it is extremely inconvenient for users to use and store it, especially under the current situation of high housing prices, and it is expensive to find a storage space for the water heating blanket main unit; (2) Heat will be lost through the main unit and the long connecting hose, wasting energy and reducing the thermal energy efficiency; (3) The existing water tank exhaust method requires frequent replenishment of circulating water to the water tank. Once the water level is exhausted, there is a risk of dry burning; (4) The high-lift water pump increases noise and cost, and the user experience is worse. Utility Model Content

[0005] In view of the technical problems existing in the prior art, the utility model aims to provide a constant temperature water heating blanket with an integrated structure of the main unit and the blanket body. The main unit and the blanket body are integrated together, and no water tank or connecting hose is required. The high-lift water pump is also abandoned, thereby realizing the miniaturization, lightness and integration of the constant temperature water heating blanket, reducing costs and noise, and greatly improving the sense of security and experience.

[0006] Specifically, in order to solve the above technical problems, the following solution is proposed, that is, the utility model provides a constant temperature water heating blanket with an integrated main unit and a blanket body, including a main unit and a blanket body, which are integrated together to form an integrated structure.

[0007] Optionally, one corner of the carpet body has an opening, and the host is fixed in the opening.

[0008] Optionally, the host is snapped into the opening and sealed by a plastic part.

[0009] Optionally, the host is fixed in the opening by screws.

[0010] Optionally, the host and the blanket body are connected by plugging.

[0011] Optionally, the host and the blanket are connected by welding.

[0012] Optionally, the main unit includes a main unit cover and a base, a first water inlet is provided on the main unit cover, a controller, a return water chamber, a water pump and a heater are provided inside the main unit, the return water chamber includes a return water chamber silicone sealing soft cover, a sealing plug is provided on the return water chamber silicone sealing soft cover, a water outlet and a return water outlet are also provided on the return water chamber, the water outlet is connected to the water pump through a water pump inlet pipe, the water pump outlet elbow is connected to the water inlet end of the mattress circulation pipeline, and the return water outlet is connected to the return water end of the mattress circulation pipeline, and the controller is used to control the water pump and the heater.

[0013] Optionally, the host is connected to an external power source via a power cord.

[0014] Optionally, an NTC temperature measuring probe fixed by an NTC sealing seat is further provided in the return water chamber.

[0015] Optionally, a water pump shock-absorbing sleeve is provided on the water pump.

[0016] Due to the adoption of the above technical solution, the beneficial effects of the utility model include:

[0017] (1) The main unit and blanket are integrated together, eliminating the need for a separate water tank to store water, eliminating the need for hose connections when in use, and eliminating the need to drain the water inside when stored. This simplicity and convenience greatly improves the usability of the water heating blanket, making it much easier to lay out and store the blanket as the seasons change, saving storage space and eliminating the need for additional living costs. Furthermore, when a constant temperature water heating blanket malfunctions, it can be easily repaired or replaced.

[0018] (2) Because there is no long connecting hose, heat is prevented from being lost to the outside through the main unit and the connecting hose, making the product more efficient and energy-saving;

[0019] (3) Due to the integrated structure, the water circulation of the integrated constant temperature water heating blanket is basically on the same horizontal plane when in use, thus avoiding the water level difference between the main unit and the blanket body and the need for a high-lift water pump, further saving costs, reducing noise, and greatly improving the sense of security and experience.

[0034] Optionally, the main unit 1 includes a main unit cover 3 and a base 4. The main unit cover 3 is provided with a first water inlet. The main unit 1 is provided with a controller (not shown), a water return chamber 5, a water pump 6, and a heater 7. The water return chamber 5 includes a silicone sealing soft cover 8 with a sealing plug 9. The water return chamber 5 also has a water outlet and a water return port. The water outlet communicates with the water pump 6 via a water pump inlet pipe 10. The water pump outlet elbow 11 is connected to the water inlet of the mattress circulation pipe 12, and the water return port is connected to the water return of the mattress circulation pipe 12. A PPS (polyphenylene sulfide) insulation pad 15 is provided between the water return chamber 5 and the heater 7. The controller is used to control the water pump 6 and heater 7. Optionally, the heater 5 is an electric heating wire, a heating tube, or a PTC (Positive Temperature Coefficient) heater.

[0035] Optionally, the host 1 is connected to an external power source via a power cord 13. A power cord guard coil may be provided on the power cord 13. In order to further reduce the volume, thickness or weight of the host, part of the electronic circuit has been assembled on the power cord 13.

[0036] Optionally, an NTC temperature probe fixed by an NTC sealing seat 16 is further provided in the water return chamber 5. The NTC temperature probe measures the water temperature by the change of the resistance value.
