Description

Technical Field

[0001] This utility model belongs to the field of daily necessities, and in particular relates to heating products. Background Technology

[0002] Using heating devices to heat the bed surface in winter is the choice of most families. Nowadays, the mainstream devices for heating the bed surface are electric blankets and water-heated blankets. However, electric blankets heat the bed by passing heating wires through the fabric, which poses a certain fire risk. Due to structural limitations, it is difficult to use temperature sensors to measure the temperature of electric blankets, making it difficult to achieve accurate temperature control. Therefore, most electric blankets only offer options for different temperature settings.

[0003] Water-heated blankets offer more comfortable temperature control and a lower probability of accidents compared to electric blankets, making them a better choice. However, traditional water-heated blankets currently face several problems. They require a designated storage space (usually a bedside table) to house the device, and the device must be placed horizontally. Because traditional water-heated blankets often have open tanks, there's a risk of spills or the device malfunctioning due to a safety feature. Furthermore, traditional water-heated systems require regular maintenance of the heat transfer fluid in the main unit. These common issues with traditional water-heated blankets detract from the user experience. Utility Model Content

[0004] The purpose of this utility model is to provide a water-heated blanket main unit to solve the technical problem of the inconvenience of using traditional water-heated blankets.

[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows: A water-heated blanket main unit, characterized in that it includes a water bladder and a controller. The controller is equipped with a water supply pipe and a control cable, and the control cable is connected to the water bag. The water bladder is equipped with an inlet pipe and an outlet pipe. The outlet pipe is connected to the controller. The water bladder is equipped with a heating device and a temperature control sensor. The inlet pipe and the supply pipe are connected to the water-heated blanket.

[0006] Furthermore, the water bladder is provided with an exhaust port.

[0007] Furthermore, the controller includes a power management system, a temperature controller, and a water pump; the water outlet pipe and the water supply pipe are connected within the controller via the water pump.

[0008] Furthermore, the water bladder is suspended.

[0009] Furthermore, a shaping rod is provided inside the water bladder.

[0010] The technical solution of this utility model has the following advantages: 1. During the overall installation, the water-heated blanket unit is suspended beside the bed. This installation method eliminates the need to reserve space at the head of the bed (such as a bedside table) for the water-heated blanket unit, which is required by traditional water-heated blanket controllers.

[0011] 2. This avoids the situation where the heat transfer fluid in the main unit of a traditional water-heated blanket overflows when the shelf is accidentally knocked over due to an impact.

[0012] 3. It solves the problem of traditional water-heated blankets requiring frequent replenishment of heat-conducting fluid, achieving the goal of maintenance-free operation. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is a schematic diagram of the structure of the water bladder of this utility model. Detailed Implementation

[0014] To better understand the purpose, structure, and function of this utility model, the following detailed description of a water-heated blanket main unit of this utility model is provided in conjunction with the accompanying drawings.

[0015] Example 1 like Figure 1 and Figure 2 As shown, the present invention provides a water-heated blanket main unit, which includes a water bladder 2 and a controller 1.

[0016] The main body of the water bladder 2 is made of PVC film, and the surface of the water bladder 2 can be covered with Oxford cloth or velvet material as needed. For example, the Rainbow 325-G hot water bottle and the Jisu Warmer Life1 hot water bottle.

[0017] Specifically, the controller 1 is equipped with a water supply pipe 13 and a control cable 11, which is connected to the heating device 25 and the temperature control sensor 26 inside the water bladder 2.

[0018] Specifically, the water bladder 2 is equipped with an inlet pipe 22 and an outlet pipe 12, and the outlet pipe 12 is connected to the water pump in the controller 1.

[0019] In practical applications, the heating device 25 can use a 220V, 300W heating rod or, depending on the cost budget, a PTC heating element. A 12V centrifugal water pump is used.

[0020] In practical use, the inlet pipe 22 of the water bladder 2 is first connected to the water-heated blanket, and then the outlet pipe 12 of the water bladder 2 is connected to the controller 1. The controller 1 is then connected to the water-heated blanket via the supply pipe 13, thus forming a water circulation system. The entire water circuit is closed to avoid frequent maintenance issues caused by water evaporation.

[0021] Compared to existing solutions, the water bladder 2 can maintain basic water storage while isolating the water path from air. Furthermore, during heating, the flexibility of the water bladder 2 allows it to maintain water pressure balance in the water path after the liquid expands due to heat.

[0022] Example 2 In this embodiment, the water bladder 2 is provided with an exhaust port 21. If the pressure is observed to be too high through the appearance of the water bladder 2, air can be expelled through the exhaust port 21 to maintain the water circuit at a suitable pressure, and the exhaust port 21 also has the function of injecting water.

[0023] The water bladder 2 has an exhaust port 21, a water inlet pipe 22, a water outlet pipe 12, and an installation port for connecting to the control cable 11 from top to bottom. This arrangement can keep the gas released from the liquid during use at the top of the water bladder, preventing air from entering the water pump in the controller 1 and causing excessive noise.

[0024] Example 3 In this embodiment, the controller 1 includes a power management system, a temperature controller, and a water pump. The outlet pipe 12 and the supply pipe 13 are connected within the controller 1 via the water pump. A one-way check valve is provided at the connection between the water pump and the supply pipe 13.

[0025] The power management module is mainly responsible for managing the power supply to the water pump, temperature controller, and heater.

[0026] The temperature controller is used to set the temperature required by the user, read the current temperature in the water tank, and control the on / off state of the heater based on the user-set temperature and the temperature of the water in the water tank, thereby maintaining the water in the water tank at the user's desired temperature.

[0027] The water pump is mainly used to maintain the circulation of the entire water circuit, ensuring that the temperature required by the user is brought into the water-heated blanket.

[0028] The temperature controller is connected to the heating device 25 and temperature sensor 26 in the water bladder 2. The heating device 25 also includes over-temperature protection. The heating device in the water bladder 2 is connected to the controller 1 to control and heat the liquid in the water bladder 2.

[0029] In Chinese patent document CN202411173393.6, "Water-heated Blanket and its Heating Control Method, Device, Storage Medium and Program Product," and in the DSCN brand HD-1902 water-heated blanket product on the market, there are relevant disclosures and applications regarding the power management module, temperature controller, and control module for water pump and temperature control, which will not be elaborated here.

[0030] Example 4 In this embodiment, the water bladder 2 is provided with hooks or holes to facilitate hanging the water bladder 2.

[0031] Example 5 The water bladder 2 is equipped with a shaping rod 24 to maintain the stability of the shape of the water bladder 2.

[0032] Example 6 In this embodiment, a diaphragm pump is also connected to the water supply pipe 13, and a drain pipe is connected to the diaphragm pump. The diaphragm pump can automatically supply water and drain (change water) the heated blanket.
