[0001] The utility model belongs to towel humidifying equipment, in particular to an energy-saving heat-insulating heating water tank and a towel machine using the water tank. Background Art

[0002] A towel machine is a device that humidifies dry towels. When working, it delivers hot water to the dry towels to moisten them and maintain the corresponding temperature, so that the wet towels maintain a suitable temperature to improve the comfort of use.

[0003] The water tank used in the existing towel machine has the following defects:

[0004] 1. Some water storage tanks use a single-layer thin-wall heating method, which has fast heat dissipation, is not energy-saving, and is built-in and invisible. The scale impurities generated during use are inconvenient and difficult to clean;

[0005] 2. Most of the water supply lines use plastic water tanks with instant heating, which may cause the water temperature to fluctuate. Utility Model Content

[0006] The technical problem to be solved and the technical task proposed by the utility model are to overcome the defects of the water tank used in the existing towel machine, such as fast heat dissipation, no energy saving, and inconvenient cleaning of scale impurities, and to provide an energy-saving, heat-insulating and heating water tank, and on this basis maintain the stability of the water temperature.

[0007] In order to achieve the above-mentioned purpose, the energy-saving heat preservation heating water tank of the utility model is characterized by comprising:

[0008] The thermos cup body is composed of an inner wall and an outer wall, a gap is maintained between the inner wall and the outer wall, and a mouth is arranged at the upper end of the thermos cup body;

[0009] The heating plate is sealed and welded to the lower end of the thermos cup body and defines a water storage chamber with an opening together with the thermos cup body;

[0010] The water tank cover can be opened, and the water tank cover comprises a plug. When the water tank cover is closed, the plug blocks the mouth of the tank body, and when the water tank cover is opened, the plug opens the mouth of the tank body.

[0011] The insulated water tank forms a sandwich structure by maintaining a gap between the inner wall and the outer wall, which gives the water tank an insulation function and avoids rapid heat dissipation. In addition, the mouth at the upper end of the thermos cup body can open the water storage cavity, so that the heating plate is visible, which is conducive to cleaning scale impurities generated during use. Furthermore, a water tank cover with a plug is provided for the mouth. When the water tank cover is closed, the plug blocks the mouth of the box body, and when the water tank cover is opened, the plug opens the mouth of the box body. Therefore, when the plug of the water tank cover blocks the mouth of the box body, the entire insulated water tank is insulated by the gap and the first insulation layer, which prevents the stored water from transferring heat to the outside, so that the stored water is kept warm for a long time.

[0012] Preferably, a temperature sensor is installed on the bottom surface of the heating plate to detect the bottom plate temperature in real time, accurately control the water temperature, achieve continuous constant temperature, and ensure the constant temperature of the water used to wet each dry towel.

[0013] Preferably, a temperature cutout and a temperature fuse are installed on the bottom surface of the heating plate to prevent the heating plate from drying out.

[0014] Preferably, the heating plate is embedded inside the inner wall and welded to the inner wall, and the lower edge of the outer wall is lower than the upper surface of the heating plate and welded to the outer surface of the inner wall, thereby ensuring the sealing effect.

[0015] Preferably, the gap extends downward to the radially outer side of the heating plate to avoid rapid heat dissipation at the welding position.

[0016] Preferably, there are air holes on the water tank cover to prevent the water tank from being pumped into negative pressure by the water pump, resulting in different water output.

[0017] Preferably, the upper end of the thermos cup body is provided with a transfer cover for assembling and fixing the cup body. Accordingly, the cup body can be conveniently fixed and assembled by the transfer cover.

[0018] Preferably, a water level sensor is arranged in the water storage chamber, the water level sensor is mounted on the adapter cover, and the water delivery pipe is mounted on the adapter cover. This structure takes into account the opening and closing of the stopper mouth and the installation of the water delivery pipe and the water level sensor.

[0019] To achieve the above purpose, the towel machine of the utility model includes a main machine, in which the energy-saving heat preservation heating water tank of the utility model is configured, and the water tank cover is assembled on the main machine. Thus, the water tank is prevented from dissipating heat quickly, and the water storage and heat preservation are made lasting. It is also helpful to clean the scale impurities generated during use.

[0020] Preferably, the water tank is installed in the main unit through a support plate at the bottom and a top plate at the top, so as to ensure the stability of the water tank and the convenience of installation.

[0021] The utility model forms a sandwich structure by maintaining a gap between the inner wall and the outer wall of the water tank, thereby giving the water tank a heat preservation function and avoiding rapid heat dissipation. In addition, the mouth at the upper end of the thermos cup body can open the water storage cavity, so that the heating plate is visible, which is conducive to cleaning scale impurities generated during use. Furthermore, a water tank cover with a plug is provided for the mouth. When the water tank cover is closed, the plug blocks the mouth of the tank body, and when the water tank cover is opened, the plug opens the mouth of the tank body. Therefore, when the plug of the water tank cover blocks the mouth of the tank body, the entire heat-insulating water tank is insulated by the gap and the first insulation layer, and the heat transfer from the stored water to the outside is blocked, so that the stored water is kept warm for a long time.

[0041] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0042] The terms "including" and "having" and any variations thereof in the specification and claims of the present utility model are intended to cover non-exclusive inclusions. For example, a method or product comprising a series of technical features is not necessarily limited to those technical features clearly listed, but may also include other technical features that are not clearly listed and can be included in the method or product.

[0043] In the description of the present utility model, it is necessary to understand that the technical features defined by the terms "first", "second" and the like with sequential concepts are only for the purpose of clearly describing the defined technical features so that the defined technical features can be clearly distinguished from other technical features, but do not represent such naming in actual implementation, and therefore cannot be understood as a limitation of the present utility model.

[0044] The present invention is described in detail below in conjunction with specific embodiments and drawings.

[0045] like Figure 1 , Figure 3-4 As shown, the energy-saving heat-insulating heating water tank 200 includes a heat-insulating cup body 210, a heating plate 220, a water tank cover 230, an adapter cover 270, a water level sensor 280, a water pipe 290, a temperature sensor 240, a temperature cutout 250 and a temperature fuse 260.

[0046] The thermos cup body 210 is composed of an inner wall 211 and an outer wall 212 made of stainless steel. A gap 214 is maintained between the inner wall 211 and the outer wall 212. The gap 214 maintains a negative pressure, such as reaching a near vacuum state, to block the path of the water in the thermos water tank from conducting heat outward through the wall of the water tank. A mouth 215 is provided at the upper end of the thermos cup body 210. The mouth is as large as possible to facilitate adding water to the thermos cup body 210 and cleaning the thermos cup body.

[0047] The heating plate 220 is sealed and welded to the lower end of the thermos cup body 210 and defines a water storage chamber 216 with a mouth 215 together with the thermos cup body. The heating plate 220 is formed by die-casting an electric heating tube in a cast aluminum material. In this way, the effect of bottom heating and side wall vacuum insulation is achieved. In particular, the heating plate 220 is embedded in the inner side of the inner wall 211 and welded to the inner wall. The lower edge 213 of the outer wall is lower than the upper surface of the heating plate 220 and is welded to the outer surface 211 of the inner wall 211. The gap 214 extends downward to the radial outer side of the heating plate 220 to increase the insulation effect.

[0048] The water tank cover 230 is rotatably assembled on the main unit 100 of the towel machine described below through the arm 233 and can be opened, which is convenient for adding water and maintaining the hygiene in the tank. The water tank cover 230 is a component of the top surface of the main unit 100 and is opened or closed by flipping. After closing the water tank cover, the appearance is flat and beautiful, and the thermos cup body is hidden. The water tank cover 230 includes a plug 231. When the water tank cover is closed, the plug 231 blocks the mouth 215 of the box body, and when the water tank cover is opened, the plug 231 opens the mouth 215 of the box body. Accordingly, the path for the water in the water storage chamber 216 to transfer heat to the outside through the mouth is blocked, especially the path for transferring heat to the outside through thermal convection is blocked. The water tank opening is directly facing the outside, and the inside of the water storage chamber can be seen when the water tank cover is opened, which is convenient for adding water and cleaning and maintenance. In order to achieve sealing, a silicone seal is set on the plug 231. In addition, a vent hole 232 is arranged on the water tank cover to balance the air pressure inside and outside the water storage chamber when the stopper closes the mouth, so as to avoid the water tank being pumped into negative pressure by the water pump, resulting in different water output.

[0049] The adapter cover 270 is disposed on the upper end of the thermos cup body, such as being connected to the upper end of the thermos cup body by threads. A first sealing ring 271 is disposed between the adapter cover 270 and the thermos cup body 210 to achieve sealing between the adapter cover and the thermos cup body.

[0050] The water level sensor 280 and the water pipe 290 are mounted on the adapter cover 270 and extend into the water storage chamber 216. The water level sensor is used to detect whether the water storage chamber is short of water. When the water storage chamber is short of water, heating and towel making cannot be started. The water pump 104 transfers the water in the water storage tank to the towel bin 105 through the water pipe 290 to complete the water filling of the dry towel 300. The adapter cover is removed from the thermos cup body, and the water level sensor and the water pipe can be removed from the water storage chamber.

[0051] The temperature sensor 240, the temperature cutout 250 and the temperature fuse 260 are fixed to the bottom surface of the heating plate 220. The temperature sensor is used to detect the water temperature in the heat preservation water tank, and the temperature cutout and the temperature fuse are connected in series with the heating plate to prevent dry burning.

[0052] The water level sensor 280 and the temperature sensor 240 are as follows Figure 6The computer system motherboard 106 controlled by the wet towel machine is shown. The water level sensor can detect the water level in the thermal insulation water tank in real time. When the water level in the thermal insulation water tank drops to a set position, the system control motherboard can instruct an alarm, and the alarm form includes but is not limited to a phoenix sound and / or a flashing light. The water level sensor preferably adopts a floating method. When the lack of water is detected, the remaining water at the bottom of the water tank can ensure sufficient water to wet a towel. The temperature detected in real time by the temperature sensor can be displayed on the display panel 107, which is clear at a glance.

[0053] Figure 2 , Figure 5 A towel dryer equipped with the aforementioned energy-saving, heat-insulating and heating water tank is shown. The towel dryer includes a main unit 100, in which the aforementioned energy-saving, heat-insulating and heating water tank 200 is arranged, and a water tank cover 230 is rotatably assembled on the main unit 100. The water tank is fixedly installed in the main unit through a support plate 101 at its bottom and a top plate 102 at its top. A second sealing ring 272 is arranged between the upper end of the adapter cover 270 and the top plate 102. In the assembled state, the adapter cover 270 and the top plate 102 are assembled to fix the cup body. The top plate 102 is fixed to the main unit 100. The second sealing ring 272 is squeezed between the upper end of the adapter cover 270 and the top plate 102 to achieve sealing of this part. Moreover, the top plate 102 has a circular hole-shaped water inlet 103 corresponding to the mouth. When the water tank cover is closed, the plug 231 blocks the water inlet 103 to achieve sealing, and when the water tank cover is opened, the plug opens the water inlet. Accordingly, the water tank cover cooperates with the top plate to close or open the mouth. The water filling port is viewed as a component of the mouth 215.

[0054] The water tank cover 230 is also provided with a hook 234, and the edge of the top plate 102 has a hooking portion 108. When the water tank cover 230 is closed, the hooking portion 108 is hooked by the hook 234, and the water tank cover is maintained in a state where the mouth is blocked to achieve sealing and heat preservation.

[0055] like Figure 5 As shown, you can open the water tank cover to add water to the water filling port, and it is also convenient to clean the water storage chamber.

[0056] The water tank is relatively hidden inside the wet towel machine, and it is convenient to add water, and it has vacuum insulation and energy saving. It intelligently monitors the water temperature and water volume to ensure that when a water shortage alarm occurs during the towel making process, the towels being wetted still have sufficient water.

[0057] When working, the towel pressing switch 109 is pressed, and the towel bin 105 is driven by the towel making motor 110 and the transmission mechanism to move a compressed dry towel out of the case, and then the water pump will transport the water in the water tank to the towel bin through the water pipe 290 to wet the compressed dry towel in the towel bin. The battery provides power for the entire wet towel machine, and the battery can be charged through the charging interface 111 or directly provide power for the wet towel machine.

[0058] Based on the above structure, the energy-saving heat preservation heating water tank and towel machine shown in the figure can achieve the following technical effects:

[0059] 1. The cup body is vacuum insulated and the bottom is heated to achieve constant temperature and energy saving, and the temperature of the towel is stable when preparing;

[0060] 2. The thermostatic water tank has an open mouth for easy cleaning and maintenance. The thermostatic water tank and heating are integrated into one, which is small in size and easy to install;

[0061] 3. Intelligently monitor water temperature and water volume to ensure that when a water shortage alarm occurs during the towel making process, the towel still has sufficient water.
