Description

Technical Field

[0001] The utility model relates to the field of household appliances, in particular to a water-heating blanket host and a water-heating blanket. Background Art

[0002] In winter life, electric blankets are an indispensable electrical product that can greatly improve people's sleep quality. Traditional electric blankets have electric heating wires laid inside fabric mats, and users actually sleep on the heating wires or even are wrapped in them. This is actually a very dangerous product structure. Although traditional electric blankets have taken many measures to ensure safety, the essential working principle remains unchanged, and there are still hidden concerns.

[0003] Therefore, engineers designed a completely new electric blanket, namely a water-heating blanket. The working principle of a water-heating blanket is to use water pipes instead of electric heating wires to distribute in the fabric mat. By circulating hot water in the water pipes, the heat is evenly distributed in the fabric mat to provide heating for the user. Compared with traditional electric blankets, water-heating blankets usually have an additional peripheral structure, namely the water-heating blanket host, which is mainly used to provide hot water and promote the circulation of hot water.

[0004] Most of the existing water heating blanket hosts are horizontal flat structures. This structure is relatively stable, not easy to tip over, and safer to use. However, its disadvantages are also obvious. The internal structure is relatively narrow and cannot carry a large water tank. It is inconvenient to install a water pump, not to mention providing other auxiliary functions. Utility Model Content

[0035] The technical solution of the present invention and how the technical solution solves the above-mentioned technical problems are described in detail below with specific embodiments.

[0036] The embodiment of the first aspect of the present application provides a water heating blanket host, such as Figure 1 to Figure 3 As shown, it includes a vertical water tank 100, a water pump assembly 200 and a control circuit board 300. The vertical water tank 100 is a component for storing heating medium. Water is mostly used in daily life, and tap water can be used directly. The water tank of the water heating blanket host of the present application adopts a vertical water tank 100, which has a higher vertical dimension, a higher center of gravity, and the horizontal width, length or diameter are all smaller than the vertical height.

[0037] The water pump assembly 200 at least includes a water pump 210 and a connector 220. The water pump 210 is installed on the outer wall of the vertical water tank 100 through the connector 220, and the water outlet pipe 211 of the water pump 210 extends into the chamber of the vertical water tank 100. The water pump 210 is directly installed on the vertical water tank 100, and the water outlet pipe 211 of the water pump 210 is directly connected to the water inlet 150 on the vertical water tank 100 without being connected through other water pipes. The water pumped back from the outside by the water pump 210 directly enters the vertical water tank 100 from the water outlet pipe 211. The function of the connector 220 is to fix the water pump 210 at the set position of the vertical water tank 100 to ensure its stable operation, and also to ensure the sealing between the water pump 210 and the vertical water tank 100.

[0038] The control circuit board 300 is installed on the outer wall of the vertical water tank 100, and the control circuit board 300 is electrically connected to the water pump 210. The vertical water tank 100 not only serves as a storage component for the circulating heat medium, but also serves as a mounting base for supporting structural members or other parts. As a key electronic component in the water heating blanket host, the control circuit board 300 needs to be prevented from getting wet. Placing it on the outer wall of the vertical water tank 100 can prevent it from contacting water, and can make full use of the space beside the vertical water tank 100, and use a circuit board with a lower cost. The circuit board that controls the operation of the water heating blanket host of this application is easy to find a mature product in the prior art, which realizes the functions of switching the water pump 210, processing temperature information, and preventing dumping, etc. This application does not go into further detail about the control circuit board 300.

[0039] The water heating blanket host provided by the utility model adopts a vertical water tank 100 with a larger water tank capacity. A water pump 210 is provided on the outer wall of the vertical water tank 100. The water outlet pipe 211 of the water pump 210 is directly connected to the vertical water tank 100, which reduces the use of water pipes, makes the structure more streamlined, and facilitates production and maintenance.

[0040] Optionally, in a first implementation of the first aspect of the present application, Figure 1 to Figure 3 As shown, the water heating blanket host also includes a top cover 400 and a bottom frame 500. The top cover 400 is provided with a through hole, and the vertical water tank 100 is located directly below the through hole; a sealing cover 120 is provided on the top of the vertical water tank 100, and the sealing cover 120 can cover the through hole and be connected to the vertical water tank 100; a heat dissipation window is provided on the bottom frame 500, and the vertical water tank 100 is located directly above the heat dissipation window. The top cover 400 and the bottom frame 500 are both structural parts of the water heating blanket host and installation bases capable of carrying other parts. The sealing cover 120 on the vertical water tank 100 can be provided with a sealing structure on the cover to achieve a sealed connection with the box body 110 of the vertical water tank 100, thereby avoiding circulating heat medium, that is, avoiding evaporation or overflow of water.

[0041] Specifically, Figure 3 and Figure 4 As shown, a plurality of anti-loosening grooves are arranged on the side end surface of the connection part of the sealing cover 120, and a sealing gasket is arranged inside the sealing cover 120. A rubber pad or a silicone pad can be arranged on each anti-loosening groove, or each anti-loosening groove is made of a sealable material such as rubber or silicone. When the sealing cover 120 is rotated and installed, the anti-loosening grooves are elastically pressed against the corresponding raised positions on the side wall of the water inlet of the vertical water tank 100, so that the sealing cover 120 and the vertical water tank 100 can be sealed. Figure 1 and Figure 2 As shown, in addition to the top cover 400 and the bottom frame 500, the water heating blanket host also includes a first outer cover 710 and a second outer cover 720. The first outer cover 710, the second outer cover 720 and the vertical water tank 100 constitute the main structure of the water heating blanket host. A transparent observation window can also be set on the first outer cover 710 close to the vertical water tank 100, and the box body 110 of the vertical water tank 100 is made of transparent material, so that the user can watch the water level in the box body 110 at any time through the transparent observation window. Alternatively, a transparent observation window is directly set on the vertical water tank 100, and the transparent observation window protrudes out of the first outer cover 710.

[0042] The base frame 500 is provided with a power connector 510, a water outlet pipe connector 520 and a water inlet pipe connector 530, wherein the power connector 510 is connected to electrical components such as the control circuit board 300, one end of the water outlet pipe connector 520 is connected to the water outlet 160 of the vertical water tank 100, the water outlet pipe 211 of the vertical water tank 100 is arranged on the side wall of the bottom, one end of the water inlet pipe connector 530 is connected to the water pump 210 through a water pipe, and the other end is connected to the pipe connector of the water heating blanket.

[0043] Specifically, in combination with the first aspect embodiment and the above implementation, in the second implementation of the first aspect embodiment, as Figure 1 and Figure 3 As shown, the main unit of the water heating blanket also includes a light board 600; the top cover 400 includes a transparent area 410, the light board 600 is arranged below the transparent area 410, and the light board 600 is electrically connected to the control circuit board 300. The light board 600 is arranged on the main unit of the water heating blanket for lighting, so that people can use it as a temporary lighting fixture at night. Since the main unit of the water heating blanket of the present application adopts a vertical water tank 100, combined with a corresponding housing, it can have a larger internal installation space, it is easier to set up lamps, and more obvious and easy-to-operate external buttons can also be set.

[0044] Optionally, in combination with the first aspect embodiment and the above implementation, in a third implementation of the first aspect embodiment, Figure 3As shown, the vertical water tank 100 includes a box body 110 and a heating base plate 130, and the heating base plate 130 is sealed and connected to the bottom edge of the box body 110; the heating base plate 130 is electrically connected to the control circuit board 300. Specifically, the heating base plate 130 includes a connecting plate and an electric heating plate, and the electric heating plate is embedded in the connecting plate, and the electric heating plate is electrically connected to the control circuit board 300; a sealing gasket matching the bottom profile of the box body 110 is provided on the connecting plate. The electric heating plate can specifically adopt a PTC thermistor, and the PTC thermistor is embedded in the aluminum connecting plate, so that the vertical water tank 100 becomes an electric kettle. In addition, a sudden jump thermostat can be set in the heating base plate 130, so that the vertical water tank 100 has overheating protection.

[0045] Optionally, in combination with the first aspect embodiment and the above implementation, in a fourth implementation of the first aspect embodiment, Figure 2 and Figure 3 As shown, the vertical water tank 100 also includes a water level sensor 140 disposed above the water outlet pipe 211 of the water pump 210, and the water level sensor 140 is electrically connected to the control circuit board 300. The water level sensor 140 is used to detect the water level in the vertical water tank 100 to ensure that there is a specified amount of water in the vertical water tank 100. Once the water level is lower than the specified amount, the control circuit board 300 controls the heating base plate 130 to stop running, controls the water pump 210 to stop running, and can also send out a prompt message to ensure the safe operation of the water heating blanket host. The water pump 210 is disposed at the middle position in the height direction of the vertical water tank 100, and the water level sensor 140 is disposed above the water outlet pipe 211 to ensure that the water level in the vertical water tank 100 is higher than the pipe mouth of the water outlet pipe 211, and ensure that there is enough water in the vertical water tank 100. The water level submerges the outlet pipe 211 of the water pump 210, which can greatly reduce the noise generated by the circulating water. Since the position of the water pump 210 is relatively high, the circulating water with a lower temperature sucked by the water pump 210 can quickly fall to the bottom of the vertical water tank 100, ensuring that the water in the vertical water tank 100 absorbs the heat of the heating base plate 130 more efficiently and the temperature rises faster.

[0046] In combination with the first aspect embodiment and the above implementation, in a third implementation of the first aspect embodiment, as Figure 1 and Figure 2As shown, the connector 220 includes a clamping frame 221 having a plurality of connecting ears; the connecting ears are connected to the outer wall of the vertical water tank 100 to fix the water pump 210 through the clamping frame 221. Specifically, the connector 220 also includes a sealing ring 222, which is sleeved on the outlet pipe 211 of the water pump 210, and one side of the sealing ring 222 abuts against the outer wall of the vertical water tank 100, and the other side of the sealing ring abuts against the side wall of the water pump 210 near the outlet pipe 211. The clamping frame 221 has a surrounding ring portion and a pressing bottom, which wraps and clamps the water pump 210 to ensure that the water pump 210 is securely installed. As shown in the figure, the sealing ring 222 can be a cylindrical structure with radial convex rings at both ends, so as to be arranged on the water inlet 150 of the vertical water tank 100 that matches the outlet pipe 211.

[0047] Optionally, in combination with the first aspect embodiment and the above implementation, in a fifth implementation of the first aspect embodiment, Figure 1 and Figure 2 As shown, the water heating blanket host further includes a temperature sensor 800, which is electrically connected to the control circuit board 300 and detects the temperature of the solution in the vertical water tank 100. At least a portion of the temperature sensor 800 is in contact with the solution in the vertical water tank 100.

[0048] Based on the same technical concept, the embodiment of the second aspect of the present application also provides a water-heating blanket, including a blanket body and a water-heating blanket main unit as in any one of the first aspect of the present application; the water-heating blanket is connected to the blanket body and supplies circulating fluid to the blanket body. The water-heating blanket of the present application uses a water-heating blanket main unit including a vertical water tank, which has a larger water tank volume and can support a blanket body with a larger area. A water pump is provided on the outer wall of the vertical water tank, and the water outlet pipe of the water pump is directly connected to the vertical water tank, which reduces the use of water pipes, makes the structure more streamlined, and is convenient for production and maintenance.
