Description

Dryer using heat exchanger

The present invention relates to a dryer utilizing a heat exchanger, and more particularly, to a dryer using a new heat exchanger that can improve drying efficiency and contribute to energy saving by appropriately utilizing waste heat while drying a drying object with hot air.

In general, shoes or clothing should be washed periodically after use, and washed shoes or clothing need to be dried. In order to dry shoes or the like, a dryer may be installed in an office or home. Cabinets installed in offices and homes only have a function of storing shoes or clothes, and a separate dryer is required for drying shoes and clothes. If you just put your shoes in the cabinet, the smell of the shoes will still exist, and even if you put the shoes in the cabinet and put them on again, you will have a bad feeling of wearing because the sweat stays inside the shoes. There is often a need for a dryer to suck and dry. If the user wears the shoes for a long time, the sweat from the feet will be moistened on the shoes, and if these shoes are left in the cabinet, the inside of the cabinet will be filled with odor and the shoes will not dry out quickly. Since the wear is worse on the next wearing, there is a need for a dryer that can suck shoes and dry them quickly. Laundered laundry (including shoes, clothing, etc.) is stored in the cabinet after using natural light or drying in a dryer. Clothes and shoes stored in cabinets are dry, but long-term storage of shoes or clothing, or in wet climates such as the rainy season, the laundry is often wet or moldy, and when the laundry is wet, microorganisms or insects can form inside the cabinets It damages the wardrobe and the wardrobe, and causes bad smell, so it is not hygienic. Therefore, in order to prevent the laundry, such as clothes or shoes, from becoming wet or moldy, it is necessary to remove clothes from a closet on a sunny day, dry them or put them in a dryer, and store them in a storage cabinet. On the other hand, when drying and ventilation are simultaneously performed inside the dryer, as the heated hot air drying air is exhausted and the cold outdoor air is sucked at the same time, the internal temperature of the dryer decreases relative to the drying air temperature, thereby decreasing the drying efficiency. There is a need for dryers that utilize heat exchangers appropriately.

It is an object of the present invention to provide a dryer utilizing a new heat exchanger that can dry the object to be dried with hot air while properly utilizing waste heat to improve drying efficiency. In addition, the present invention provides a dryer utilizing a new heat exchanger that can maximize the drying efficiency by recycling (at least two or more times) recycling the hot air heat exchanged for the drying of the drying object in the heat exchanger (sensible heat exchanger) again. It aims to do it.

According to the present invention, there is provided a drying chamber for accommodating a drying object therein, and a dryer body having an air flow chamber at a circumferential position of the drying chamber; A sensible heat exchanger embedded in the air flow chamber of the dryer body; A blowing fan embedded in the air flow chamber of the dryer body to allow air to pass through the sensible heat exchanger; The dryer provided with the heat exchanger provided in the air flow chamber of the dryer body comprises a heater to be supplied to the drying chamber by converting the air supplied by the blowing fan into a hot air for drying the One technical problem is to be solved.

The present invention is to recycle the object to be dried by circulating through the sensible heat exchanger without discarding the dry hot air (waste heat) as it is, it reduces the number of operating hours or operating time of the PTC heater, the effect of saving energy and also increases the drying efficiency Will have Since each heat exchange plate of the sensible heat exchanger maintains (holds) a constant temperature, the heat and heat exchanged in the external heat are retained in the sensible heat exchanger when the external relatively cold air is introduced by the blowing fan to pass through the sensible heat exchanger. As the temperature rises, the external air (warmed external air) whose temperature is increased by heat exchange with the sensible heat exchanger is supplied to the PTC heater, so that the PTC heater heats the external air accordingly and reduces the number of operations, thereby saving energy. Not only contributes greatly, but also improves the drying efficiency.

In addition, by circulating the hot air (waste heat) coming from the drying chamber of the dryer body again in the sensible heat exchanger itself, further increases the waste heat utilization, it is possible to further reduce the PTC heater operating time to further increase the energy saving efficiency, This can lead to even more improved results in drying efficiency. When the waste heat (which can be referred to as dry hot air) rises up from the drying chamber of the dryer body and enters into the sensible heat exchanger, the waste heat flows inside the sensible heat exchanger along the guider with the circulation guide plate structure as indicated by the arrow. Since it is recycled again, the heat retained in the sensible heat exchanger itself can be increased. When the holding heat (holding heat) of the sensible heat exchanger is increased, the external air entering the dryer body passes through the sensible heat exchanger. As it is supplied to the PTC heater in an even higher state, the result is that the operation time or the number of times of operation of the PTC heater can be further reduced as compared to the absence of the guider, thereby significantly reducing the energy associated with the operation of the PTC heater. At the same time, the drying efficiency is quite high. It brings the desired results.

In addition, the present invention is to circulate the air outside the drying chamber when the air outside the dryer body is circulated to the inside of the air circulation pipe when the desired time to be properly dried inside the drying object baked in the drying chamber of the dryer body Due to the relatively low temperature of the outside air passing through the tube, condensation forms on the surface of the air circulation tube, lowering the amount of vapor in the drying chamber, and the object to be dried while lowering or absorbing the amount of vapor in the drying chamber by this condensation. By drying for an appropriate time, since the outer part of the drying object and the inner part of the drying object are uniformly dried, more safe and reliable drying quality of the drying object can be ensured.

Efficiency also has the advantage of increasing. As described above, since each heat exchange plate 24 of the sensible heat exchanger 20 maintains (holds) a constant temperature, relatively cool air from the outside is introduced by the blowing fan 30 to allow the sensible heat exchanger 20 to flow. When passing, the outside air rises as heat exchange occurs with the accumulated heat held in the sensible heat exchanger 20, and the external air (warmed external air) whose temperature rises by heat exchange with the sensible heat exchanger 20 is a PitiC heater. Since it is supplied to the PTC heater, the time for warming up the external air or the number of operations is reduced, thereby contributing to energy saving and improving the drying efficiency.

In the present invention, the sensor is installed in the drying chamber 12 of the dryer body 10, the sensor is electrically connected to the control unit, the control unit temperature inside the dryer body 10 (that is, the drying chamber 12) Temperature) is set to maintain 55 ° C. to 60 ° C., so that when the temperature (hot air in the drying chamber 12) rises to the sensible heat exchanger 20, the sensible heat exchanger 20 is approximately Since heat is maintained at about 45 ° C., when external air (approximately 25 ° C.) enters in this state, the temperature of the external air before reaching the heater 40 is increased (the temperature held by the sensible heat exchanger 20) Since the average temperature of 45 ° C and 25 ° C of 25 ° C is supplied to the PTC heater at about 35 ° C., the operating time of the PTC heater is reduced, thereby saving energy. Therefore, the present invention will be the main feature that can be used by the sensible heat exchanger 20 to discard the waste heat again to increase the drying efficiency.

On the other hand, Figure 9 is a side cross-sectional view schematically showing the structure of another embodiment of the present invention, according to the invention shown in Figure 9, the dryer body 10 is an air flow chamber 14 around the drying chamber 12 Is provided, the sensible heat exchanger 20 is built in the air flow chamber 14 so as to communicate with the drying chamber 12, the sensible heat exchanger 20 is hot air coming into the sensible heat exchanger 20 from the drying chamber 12 The guider 50 is provided so that (waste heat) is circulated again to the sensible heat exchanger 20. In the present invention shown in FIG. 9, the guider 50 extends from the rear end facing the blowing fan 30 to the air inlet end of its front end via the upper side opposite to the lower side from which the hot air enters from the drying chamber 12. It is a circulation guide plate structure. That is, the guider 50 has a circulating guide plate structure that covers from the rear end of the sensible heat exchanger 20 to the upper side of the sensible heat exchanger 20 and the front end of the sensible heat exchanger 20. At this time, the guider 50 is a sensible heat exchanger so as to secure a passage through which the outside air can be introduced into the lower side of the sensible heat exchanger 20 rather than descending to the position completely wrapped up to the lower end of the sensible heat exchanger 20. It is configured to extend from the lower end side of the 20) to the position further upward. Thus, when the blowing fan 30 rotates, external air entering the air flow chamber 14 (ie, the upper flow chamber 14a portion) of the dryer body 10 may enter and pass through the sensible heat exchanger 20. Will be.

9 is characterized in that the hot air (waste heat) coming up from the drying chamber 12 of the dryer body 10 further increases the waste heat utilization by circulating again in the sensible heat exchanger 20 itself. By further reducing the seed heater uptime, the energy savings efficiency can be further increased, which results in even more improved drying efficiency. That is, waste heat circulates as indicated by the arrow when waste heat (which may be referred to as a dry hot air to dry) rises upward from the drying chamber 12 of the dryer body 10 and is introduced into the sensible heat exchanger 20. Recirculation once again inside the sensible heat exchanger 20 along the guider structure having the guide plate structure (waste heat (hot air) from the drying chamber 12 primarily circulates inside the sensible heat exchanger 20 and then the guider). Since the waste heat circulates inside the sensible heat exchanger 20 once again by the 50, it is possible to further increase the heat retained in the sensible heat exchanger 20 itself, and thus the sensible heat exchanger 20 itself When the holding heat (holding heat) is raised to a higher state, the external air entering the dryer body 10 is supplied to the PTC heater in a further elevated state through the sensible heat exchanger 20. It is possible to further reduce the operating time or the number of times of operation of the PTC heater when compared to the case where there is no 50, thereby significantly reducing the energy associated with the operation of the PTC heater and at the same time increasing the drying efficiency. To get results.

At this time, in the present invention, the waste heat (that is, the heat rising from the drying chamber 12 inside the dryer body 10 and rising to the sensible heat exchanger 20) by the guider 50 is circulated again in the sensible heat exchanger 20. Heat exchange between the cool air and the relatively hot air (waste heat) when the relatively cold air coming from the outside of the dryer body 10 is also passed into the sensible heat exchanger 20. In view of the fact that condensation occurs in the sensible heat exchanger 20 when hot air meets, the condensation receiving plate 18 (tray) is further installed to be positioned below the sensible heat exchanger 20. That is, the condensation receiver 18 is installed in the drying chamber 12 of the dryer body 10 to be disposed below the sensible heat exchanger 20. The condensation receiver 18 has a tray structure with sidewalls, and may be fixed to the drying chamber 12 by fixing means such as a bracket and a bolt. On the other hand, the dew condensation falling from the sensible heat exchanger 20 is collected in the condensation receiving 18, in order to allow the water due to this condensation to naturally flow down the drying chamber 12 to one side. Lay out inclined. That is, it is the structure arrange | positioned so that the height of the other end may be lower than the height of the one end of the condensation bin 18, and the said inclined other end of the condensation bin 18 is adjacent to the inner wall of the drying chamber 12. FIG. It is configured to extend to the position (extended to a position in close contact with the inner wall of the drying chamber 12). Then, water falling on the condensation tray 18 naturally flows down to the other end side inclined of the condensation tray 18 and then flows down the inner wall of the drying chamber 12. At this time, a drain hole 12h is formed in the bottom portion 12a constituting the bottom of the drying chamber 12, and water flowing down the inner wall of the drying chamber 12 is drained from the bottom hole 12h of the bottom portion 12a.
