[0001] The utility model relates to the technical field of steam water heaters, in particular to a double-safety steam water heater. Background Art

[0002] Steam water heater is a kind of equipment that can provide steam and hot water, which is widely used in various fields such as household, commercial and industrial.

[0003] The device heats water to boiling and produces steam through a specific heating system, while providing hot water supply.

[0004] In the prior art, when steam is discharged, some hot water is easily taken out, causing hot water to remain inside the steam pipe, which can easily cause pipe damage. In subsequent use, the heat of the steam in the pipe will be consumed, causing energy loss.

[0005] At the same time, it is difficult to distinguish the content of water and steam in the existing steam water heaters, and it is easy to have too much water content, resulting in excessive pressure inside the steam water heater, thereby greatly reducing the safety of the steam water heater device. Utility Model Content

[0006] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a double-safety steam water heater so as to solve the technical problems mentioned in the above background technology.

[0007] The above technical objectives of the utility model are achieved through the following technical solutions:

[0008] A double-insurance steam hot water device comprises a heating shell, wherein two guide columns are arranged at the top end of the interior of the heating shell, and a heating coil is fixedly connected to the bottom end of the guide column. The device is characterized in that a water inlet pipe and a steam outlet pipe are respectively arranged at both ends of one side of the heating shell, a floating plate is arranged inside the heating shell, and a sealing mechanism is arranged at the bottom of the floating plate on the side corresponding to the water inlet pipe.

[0009] Furthermore, a ventilation groove is provided inside the floating plate, the side wall of the floating plate contacts the inner wall of the heating shell, a push tube is slidably connected inside the ventilation groove, and a closing plate that fits the bottom side of the floating plate is provided at the bottom end of the push tube.

[0010] Furthermore, a sliding hole is provided at a position of the upper end of the floating plate corresponding to the guide post, and the guide post is inserted into the sliding hole.

[0011] Furthermore, the sealing mechanism includes a fixed plate, which is installed on the bottom side of the floating plate at a position corresponding to the water inlet pipe and has a distance from the water inlet pipe. A fixed spring is provided on the side of the fixed plate facing the water inlet pipe, and a sealing plug matching the water inlet pipe is provided at one end of the fixed spring, and an outer wall of the sealing plug is provided with a guide ring fixedly connected to the bottom side of the floating plate.

[0012] Furthermore, a right-angle elbow is provided at one end of the steam exhaust pipe located inside the heating shell, and the right-angle elbow extends upward and passes through the floating plate.

[0013] Furthermore, when the sealing plug is inserted into the water inlet pipe, a gap is provided between the floating plate and the inner upper wall of the heating shell.

[0014] In summary, the present invention includes at least one of the following beneficial technical effects:

[0015] 1. This double insurance steam hot water device allows water to enter the interior of the heating shell through a water inlet pipe, and heats the water through a heating coil to generate steam. The steam floats up under the heat and is discharged through a steam discharge pipe. The floating plate is set to prevent the water from boiling when heated, effectively improving the stability of the device when heating water;

[0016] 2. In this double insurance steam hot water device, when the floating plate rises due to the buoyancy of water, the sealing plug gradually corresponds to the water inlet pipe. When the sealing plug corresponds to the position of the water inlet pipe, the sealing plug is pushed into the inside of the water inlet pipe by the setting of the fixing spring to achieve the effect of blocking the water inlet pipe, thereby preventing water from entering, causing the water level inside the heating shell to be too high and causing the problem of steam being unable to be generated;

[0017] 3. This double-insurance steam hot water device, through the setting of the ventilation groove, after the water evaporates under the influence of the heating coil, the steam passes through the ventilation groove and passes through the floating plate, and the floating plate separates the steam from the water, so as to achieve the effect of preventing the hot water from being discharged along with the steam. At the same time, the steam can be effectively squeezed out during the rising water level, so as to improve the efficiency of steam discharge. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0024] Example:

[0025] Reference Figure 1-Figure 3 The utility model discloses a double-insurance steam hot water device, comprising a heating shell 1, two guide columns 2 are arranged at the top of the interior of the heating shell 1, a heating coil 3 is fixedly connected to the bottom end of the guide column 2, a water inlet pipe 4 and a steam exhaust pipe 5 are respectively arranged at both ends of one side of the heating shell 1, a floating plate 6 is arranged inside the heating shell 1, and a blocking mechanism 7 is arranged at the side of the bottom of the floating plate 6 corresponding to the water inlet pipe 4.

[0026] In this embodiment, when in use, water is passed into the interior of the heating shell 1 through the water inlet pipe 4, and the water is heated by the heating coil 3 to generate steam. The steam floats up under the heat and is discharged through the steam discharge pipe 5. The steam is separated from the water by the setting of the floating plate 6, and the setting of the floating plate 6 can prevent the water from boiling when heated, which effectively improves the stability of the device when heating water, and can prevent water from being discharged along with the steam when the steam is discharged, so as to prevent hot water from entering the steam discharge pipe 5. Through the setting of the blocking mechanism 7, when the water level inside the heating shell 1 reaches a certain height, the blocking mechanism 7 corresponds to the water inlet pipe 4, so as to prevent the water level in the heating shell 1 from being too high.

[0027] In a further preferred embodiment of the present invention, Figure 1-3 As shown, a ventilation groove 61 is opened inside the floating plate 6, and the side wall of the floating plate 6 contacts the inner wall of the heating shell 1. A push tube 63 is slidably connected inside the ventilation groove 61, and a closing plate 64 is provided at the bottom end of the push tube 63 to fit the bottom side of the floating plate 6.

[0028] In this embodiment, through the provision of the ventilation groove 61, after the water evaporates under the influence of the heating coil 3, the steam passes through the ventilation groove 61 and passes through the floating plate 6. The floating plate 6 separates the steam from the water, thereby preventing the hot water from being discharged along with the steam. At the same time, the steam can be effectively squeezed out during the rising water level, thereby improving the efficiency of steam discharge.

[0029] In a further preferred embodiment of the present invention, Figure 1-3 As shown, a sliding hole 62 is opened at a position of the upper end of the floating plate 6 corresponding to the guide column 2 , and the guide column 2 is inserted into the sliding hole 62 .

[0030] In this embodiment, the sliding hole 62 is provided to enable the floating plate 6 to be slidably connected to the guide column 2, thereby achieving the effect of improving the stability of the floating plate 6 and preventing the floating plate 6 from deviating and getting stuck due to the fluctuation of the water surface.

[0031] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the sealing mechanism 7 includes a fixed plate 71, which is installed on the bottom side of the floating plate 6 at a position corresponding to the water inlet pipe 4 and has a spacing from the water inlet pipe 4. A fixed spring 72 is provided on the side of the fixed plate 71 facing the water inlet pipe 4, and a sealing plug 73 matching the water inlet pipe 4 is provided at one end of the fixed spring 72, and the outer wall of the sealing plug 73 is provided with a guide ring 74 fixedly connected to the bottom side of the floating plate 6.

[0032] In this embodiment, when the floating plate 6 is lifted by the buoyancy of water, the sealing plug 73 gradually corresponds to the water inlet pipe 4. When the sealing plug 73 corresponds to the position of the water inlet pipe 4, the sealing plug 73 is pushed into the water inlet pipe 4 by the setting of the fixing spring 72 to achieve the effect of blocking the water inlet pipe 4, thereby preventing water from entering. After the water inside the heating shell 1 is continuously heated, a large amount of steam is generated, and the water level drops. Due to the decrease in the total amount of water, the speed of steam generation will increase at this time, thereby causing the air pressure inside the heating shell 1 to continue to rise. Through the setting of the push pipe 63, the closing plate 64 is always in contact with the water level surface, thereby allowing steam to enter the upper end of the heating shell 1 only through the push pipe 63 and the ventilation groove 61. The floating plate 6 is pushed out from top to bottom by the pressure generated by the steam. When the steam pressure at the upper end of the heating shell 1 reaches a value greater than the elastic force of the fixing spring 72, the pressure of the steam will push the floating plate 6 to move downward, thereby achieving the effect of separating the sealing plug 73 from the water inlet pipe 4, so that the water flow can enter the interior of the device again.

[0033] In a further preferred embodiment of the present invention, Figure 1-3As shown, a right-angle elbow 8 is provided at one end of the steam exhaust pipe 5 located inside the heating shell 1 , and the right-angle elbow 8 extends upward and passes through the floating plate 6 .

[0034] In this embodiment, by setting the right-angle bend pipe 8, the entrance of the steam exhaust pipe 5 is located at the top of the interior of the heating shell 1, and then during the rising process of steam, it is discharged into the interior of the steam exhaust pipe 5 through the right-angle bend pipe 8, thereby achieving the effect of preventing water from entering the steam exhaust pipe 5.

[0035] In a further preferred embodiment of the present invention, Figure 1-3 As shown, when the sealing plug 73 is inserted into the water inlet pipe 4 , there is a gap between the floating plate 6 and the inner upper wall of the heating shell 1 .

[0036] In this embodiment, when the sealing plug 73 is inserted into the water inlet pipe 4, there is a gap between the floating plate 6 and the heating shell 1, so that steam can enter the gap between the floating plate 6 and the heating shell 1, thereby facilitating the floating plate 6 to move downward.

[0037] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
