Description

The present invention relates to a mattress heater and a mattress heating method for heating a mattress used mainly on a bed or under a mattress.

Conventionally, bedding such as mattresses, comforters, and blankets have been regularly exposed to sunlight for drying and cleaning in order to prevent house dust such as mites and dust that hinder a good night's sleep and cause allergies. ing.
However, drying the futon is a troublesome task, and it takes a lot of labor to carry the futon. Therefore, the older the person is, the less frequently the work is done, and the hygiene of the futon tends to deteriorate.
Therefore, for example, in Patent Document 1, the hot air generator of the hot air generator arranged in the center of the futon hanging back and forth from the horizontal member by hanging the futon on the horizontal member indoors without carrying the futon outdoors and Cover the futon with a cover member, blow hot air on the inner side of the folded futon to move the pests in the futon to the outer side of the futon, and then place the futon on the floor with the outer side of the futon facing up. It describes how to clean the futon by laying it on top and sucking and removing the pests in the futon from the outer surface side of the futon.
Further, in recent years, various futon cleaners have been proposed that suck and remove house dust while laying down the futon. For example, Patent Document 2 describes a handy type vacuum cleaner that weakens, sucks, and removes pests in a wide area of a futon by the exhaust air that is heated by an electric blower and discharged from the vacuum cleaner body. ing.

JP-A-2007-135703 Japanese Unexamined Patent Publication No. 2016-67729

However, since the cleaning method of Patent Document 1 uses a heating method in which heat is released from below inside the cover member to roast the futon, it is suitable for thick and hard-to-deform mattresses used in beds and the like. There was a problem that it could not be done.
On the other hand, a handy type vacuum cleaner as in Patent Document 2 is integrally provided with an operation handle that is bent in a U shape from the front end portion of the vacuum cleaner body toward the rear, and the user can operate the operation handle. Since it is used by holding it in the hand and moving it back and forth, it can be used for futons laid on the floor and mattresses on the bed. However, since the reach of the user is limited, depending on the height of the futon or mattress, you have to stretch your arms in a posture like crawl on all fours or bend your upper body. However, there was a problem that work efficiency was poor. In particular, in order to clean every corner of the futon or mattress, the worker must work in an unstable posture while moving around the futon or mattress, which prolongs the work time and causes the worker. There was also a problem that the burden on the mattress was likely to increase. Further, the vacuum cleaner of Patent Document 2 sucks the air discharged from the dust collector with an electric blower and heats an object such as a mattress by the exhaust of the electric blower, without using a heater. Only the heat generated by the electric blower is used. Therefore, there is a problem that it is difficult to sufficiently weaken or kill pests such as mites because the heating temperature is low, heating spots are likely to occur, and the heating efficiency is poor. Further, the vacuum cleaner of Patent Document 2 not only heats the object, but also taps the object by a tapping mechanism to release pests such as mites from the object, and sucks and removes them together with dust. .. For this reason, there are problems that the structure is complicated, mass productivity and maintainability are lacking, the weight is increased, it is not suitable for carrying, and it is lacking in handleability.
The present invention has been made in view of such circumstances, and the mattress can be reliably and efficiently heated from the surface to kill or weaken pests such as mites and bed bugs (bed bugs), which is a burden on the operator.

The mattress heater 10 moves mainly on a mattress used by laying it on a bed or under a mattress to heat the mattress with warm air.
As shown in FIGS. 1 to 4, the mattress heater 10 has a structure in which the hot air heater 12 is housed in the frame 11. As shown in FIGS. 1 and 3, the hot air heater 12 has a fan 13 arranged at the center of the frame 11 and a U-shaped heating source 14 arranged below the fan 13. Further, the fan 13 and the heating source 14 are supported by a cover 16 whose upper portion is covered with a top plate 15 and whose outer periphery and lower portion are formed in a mesh pattern. The hot air heater 12 in which the fan 13 and the heating source 14 are integrated in this way can be easily attached to and detached from the frame 11. The heating source 14 can be appropriately selected, but a quartz tube heater, a halogen heater, or the like is preferably used. In the present embodiment, the U-shaped heating source 14 is used, but the shape is not limited to this, and for example, two heaters may be arranged in parallel.
Further, as shown in FIGS. 1, 3 and 4, a mounting hole 18 penetrating vertically is formed in the center of the frame body 11, and the warm air heater 12 is mounted in the mounting hole 18 in a holding state. ing. As a result, the fan 13 takes in air from the center of the mounting hole 18, blows it toward the heating source 14, and exhausts the air (hot air) heated by the heating source 14 from the outside to the bottom to reach the surface of the mattress. It can be sprayed and the mattress can be heated efficiently.

Next, as shown in FIGS. 3 and 4, each inner wall surface 19 of the rectangular frame 11 in a plan view has a leaf spring-shaped heater that abuts on the outer peripheral surface 20 of the cover 16 of the warm air heater 12. Two holding portions 21 are provided. As a result, the hot air heater 12 can be held at a predetermined position in the frame 11, and the hot air heater 12 can be prevented from being displaced or vibrated during work, and reliable heating can be performed.

A handle portion 26 is formed so that the pipe can be gripped by hand. The lower end of the handle 25 is rotatably held by the shaft support 27, and wheels 28 are provided at the four corners of the bottom of the frame 11. Therefore, when the operator grasps the handle portion 26 by hand and moves the handle 25 back and forth, the angle formed by the frame 11 and the handle 25 changes according to the distance between the worker and the frame 11. As a result, the operator can smoothly move the frame 11 back and forth on the mattress and heat the mattress to every corner by the same operation as when using the vacuum cleaner in a comfortable posture. Further, the wheels 28 can secure a gap between the hot air heater 12 and the mattress, and the distance can be kept substantially constant, so that heating spots can be suppressed and the mattress can be heated efficiently. In particular, keeping the distance from the hot air heater 12 to the surface of the mattress within 10 cm is preferable because heat can be efficiently transferred. Here, the hot air heater 12 provides a safety device (not shown) that stops power supply to the heating source 14 by a bimetal thermostat, electronic control, or the like when the temperature of the heating source 14 reaches a preset upper limit temperature. It is preferable to incorporate it. As a result, the mattress can be prevented from overheating and the work can be performed safely. The heating temperature of the hot air heater 12 is 55 ° C. to 80 ° C., preferably 65 ° C. to 75 ° C. For example, bed bugs can be killed by heating them to around 70 ° C.
Further, if a cover member (not shown) that covers the gap between the frame 11 and the mattress is attached to the outer periphery of the lower portion of the frame 11, the lower portion of the frame 11 and its surroundings can be blocked, and the warm air heater 12 can be used. The surface of the mattress can be efficiently heated without letting the hot air blown out from the mattress escape to the surroundings. As the cover member, a cloth, a sheet or the like is used, and the material thereof can be appropriately selected, but it is preferable that the cover member has heat resistance.
