Description

  The present invention relates to a hot air heater using heated steam generated by superheating steam and a dryer.

Technical background

  In general, a warm air heater or a dryer heats air through a heating means such as a heater to increase the temperature, and then uses the hot air to increase the room temperature or dry an object.

  However, such a hot air heater using hot air has the disadvantage that it takes a lot of time to raise the temperature at one corner of the place where the temperature is to be raised, and the efficiency of heating is reduced. However, since the hot air is not evenly applied to the object, the dryer has a problem in that the drying efficiency is lowered over the entire object because of the local drying.

  The reason why such a result occurs is that heating or drying is performed using hot air, that is, heated air, and an alternative method has been required.

  Accordingly, interest in using heated steam as a heat source has increased recently, but heated steam generally means steam with a high amount of heat obtained by heating saturated steam further above saturation pressure and heating above saturation temperature. .

  Conventionally, a heating steam generator heats saturated steam supplied from a boiler or the like and generates a large volume of heating steam in a short time, and the heating steam generated by this generator is higher in temperature than saturated steam and is fine particles. It is used as a heat source for food and drink, cooking utensils or drying utensils.

  Cooking utensils that use heated steam have the feature of heating food and drink uniformly, and of course, it is easy to adjust the temperature and supply rate of the heated steam, as well as to prevent food and drink from burning locally. In addition to being able to adjust easily, there is an advantage that the taste does not change without causing oxidation phenomenon due to steam.

  However, the conventional heating steam generator incorporates complex components including a screw-shaped electric heater (fin heater) in order to ensure the cross-sectional area required for generating and processing the heating steam. Due to the structure, various costs are increased, and there is a problem that costs for maintenance and repairs are increased.

  The present invention has been devised in order to solve the above-described problems, and includes a hot air heater using heating steam and a dryer using heating steam so that the heating efficiency and drying efficiency are excellent. There is a purpose to provide.

And a second fan that is discharged from the hot air heater using heating steam.

  With such a configuration, it is possible to achieve a warm air heater using heated steam that has excellent heating efficiency, a simple structure, and reduced manufacturing and maintenance costs.

  In addition, it is preferable to further include a second heater attached to the duct so as to be adjacent to the discharge port of the housing.

  Moreover, it is preferable to further include a temperature sensor mounted on the duct.

  It is preferable that the apparatus further includes a water supply adjusting unit that is provided below the water supply unit and adjusts the amount of water supplied from the water supply unit to the steam generating unit.

  Alternatively, the present invention is provided in a housing having a discharge port formed on the upper surface, a second fan located inside the housing, and an upper portion of the second fan, and an upper stage is connected to the discharge port of the housing, A second duct provided with an air heater for heating the air that is introduced and moved by the second fan, and an ultrasonic wave applied to water supplied from the water supply means located in the housing.

It does not mean that the range is limited. In the description of various embodiments of the present invention, the same reference numerals are assigned to components having the same technical features.

  With reference to FIG.1 and FIG.2, the warm air heater using the heating steam by one Example of this invention is demonstrated. The dryer using the heating steam has substantially the same configuration as the hot air heater using the heating steam shown in FIGS. 1 and 2. The following description naturally applies to a dryer using heated steam.

  As shown in FIGS. 1 and 2, the dryer using the heating steam according to the present embodiment includes a housing (10), a water tank (20), steam generating means (30), a duct (40), and a first fan. (50), a first heater (60), a second fan (70), a second heater (80), a temperature sensor (90), and a water supply adjusting means (22).

  The housing (10) is hollow so that a configuration such as a water tank (20) can be built therein.

  A discharge port (not shown in the figure) is formed on the upper side of the housing (10). The discharge port is formed so that mixed heated steam and air are discharged to the outside as described later. ing.

  The water tank (20) is mounted on one side of the housing (10), and the water stored in the water tank (20) is supplied to the steam generating means (30). In this case, a water supply adjusting means (22) is provided below the water tank (20) so that the amount of water supplied to the steam generating means (30) is adjusted. The water supply adjusting means (22) includes a water supply pin (22a) and a cock (22b).

  The steam generating means (30) is mounted on the other side of the housing (10) and serves to generate steam by applying ultrasonic waves to the water supplied from the water tank (20). Such a steam generating means (30) has an ultrasonic vibrator (32) for applying ultrasonic waves to water, and steam is generated by the vibration of the ultrasonic vibrator (32). Yes.

  On the other hand, although not shown in the figure, in the steam generating means (30), a high-pressure spray that injects water in the form of fine particles at a high pressure may be applied instead of the ultrasonic vibrator (32).

  The duct (40) is installed inside the housing (10) so that the lower stage is located above the steam generating means (30) and the upper stage is connected to the discharge port of the housing (10). Thereby, the steam generated by the steam generating means (30) moves upward through the duct (40). The duct (40) is made of stainless steel and has the advantage that contamination is prevented.

  The first fan (50) is assumed to play a role of assisting the steam generated by the steam generating means (30) to move smoothly in the duct (40), and above the steam generating means (30). It is built in the housing (10) so as to be located on one side.

  The first heater (60) is attached to the duct (40), and plays a role of heating the steam generated by the steam generating means (30) in the process of passing through the duct (40). Yes. In this case, it is desirable to heat the steam so that the temperature of the steam becomes about 100 to 600 ° C. by the first heater (60), thereby generating the heating steam. The first heater (60) is preferably a far infrared heater. Far-infrared rays have the effect of suppressing the growth of bacteria, molds, etc., and activating human and plant cell tissues.

  The second fan (70) is mounted on the upper side of the duct (40). Heated steam generated by the first heater (60) is mixed with air and discharged to the discharge port of the housing (10). To play a role. In this case, the duct (40) is provided with a separate air inlet (42) outside the portion where the first heater (60) is mounted. The first fan (50) causes the steam to pass through the portion where the first heater (60) is mounted, but the second fan (70) not only moves the steam passing through the first heater (60) upward. Air is introduced from the outside through the air inhaler (42), and the heated steam and air that have passed through the first heater (60) are mixed and sent to the upper side of the duct (40). Thereby, the mixed heating steam and air are discharged from the discharge port of the housing (10). The reason why the heated steam is mixed with the external inflow air is to increase the diffusion efficiency after being discharged from the housing (10).

  As described above, the warm air heater using the heating steam according to the embodiment of the present invention may further include the second heater (80), the temperature sensor (90), and the water supply adjusting unit (22).

  The second heater (80) is attached to the duct (40) so as to be adjacent to the outlet of the housing (10) through which the mixed heated steam and air are sent out by the second fan (70). Heated steam is generated by the first heater (60) attached to the duct (40), but when the heated steam is mixed with air, the temperature is lowered, so it is necessary before being discharged to the outside. It is desirable to provide a second heater (80) that can be reheated to adjust the temperature.

  In this case, it is desirable to mount a temperature sensor (90) on the duct (40) for measuring the temperature of the mixed heated steam and air. Preferably, the temperature sensor (90) transmits temperature information to the controller (c), and the controller (c) controls the operation of the second heater (80) based on the temperature information.

  Reference numeral 92 denotes an overheat prevention sensor. The overheat prevention sensor (92) senses the temperature of the mixed heated steam and air discharged from the discharge port of the housing (10), and transmits it to the controller (c). The controller (c) is responsible for controlling the second heater (80) to stop or operate so that a fire due to excessive heating does not occur. The operation process of the warm air heater using the heating steam according to the embodiment of the present invention will be described as follows.

  First, when water is supplied from the water tank (20), ultrasonic waves are applied by the ultrasonic vibrator (32) of the steam generating means (30) to generate steam, and the steam is moved upward by the first fan (50). To the duct (40). Then, the steam is heated by the first heater (60) in the process of passing through the duct (40) to generate heated steam, and this heated steam is mixed with the air flowing from the outside. The mixed heated steam and air are moved to the upper side of the duct (40) by the second fan (70) and then discharged to the outside through the discharge port of the housing (10). In this case, if the temperature of the mixed heated steam and air detected by the temperature sensor (90) is low, the second heater (80) performs secondary processing before discharging from the discharge port of the housing (10). Is heated to adjust the required temperature.

  Since the heating steam discharged from the discharge port of the housing (10) is finer than high-temperature saturated steam, it is fine particles. Therefore, when applied as a hot air heater, it has excellent diffusibility and excellent heating efficiency. When it is applied as a dryer, it spreads evenly over the object, so that the drying efficiency is excellent throughout the object.

Here, as shown in FIG. 4, the first heater (85) is fixed to the second duct (42). Therefore, the air flowing into the second duct (42) by the second fan (70) is heated by the air heater (85) and then moves to the upper side of the second duct (42) to move the housing (100). It comes to the discharge port.

  The steam generating means (30) is installed so as to be located on the upper side inside the housing (10), but is located at a position separated from the second duct (42), and the steam generating means (30) and the second duct are arranged. (42) is connected by a first duct (41) to be described later. The steam generating means (30) is supplied with water from a water supply means (not shown), and an ultrasonic transducer (32) is provided so that steam can be generated by applying ultrasonic waves to the supplied water. have. The water supply means is provided outside the housing (10) or inside the housing (10). When provided outside the housing (10), it is connected to the steam generating means (30) by a pipe.

  One end of the first duct (41) is coupled to the other side of the steam generating means (30). On the other hand, the other end of the first duct (41) is bent upward after passing through the upper one side of the second duct (42), and is located below the discharge port of the housing (10).

  The first duct (41) is equipped with the first heater (60). The first heater (60) is configured such that the steam generated by the steam generating means (30) is generated by the first fan (50). It is heated when passing through the first duct (41) and plays a role of generating heated steam.

  Eventually, what is discharged from the outlet of the housing (10) is a mixture of heated steam and heated air. That is, heated air moves from the second duct (42) toward the discharge port of the housing (10), and in addition, heated steam flows from the first duct (41) toward the discharge port of the housing (10). It moves, and both are discharged after being mixed under the discharge port of the housing (10). The reason for mixing the air with the heating steam is to increase the diffusion efficiency as described above, and the reason for heating the air to the air heater (85) by the second duct (42) is to supplement the amount of heat. It is to do.

  The operation process of the warm air heater using the heating steam according to another embodiment of the present invention will be described as follows.
