Abstract

PURPOSE:To obtain a mattress drier with a function for automatically heating the mattress without relying on the sense of a user by setting start-up heating time inversely proportional to room temperature by a room temperature detecting means and providing a control means for controlling the heating quantity of a heater so as to have preset heat insulating temperature when the heater is heated with constant heating quantity and heating time reaches to the start-up heating time. CONSTITUTION:During the rise of the temperature of hot air, when count time reaches the time of a first process, a course setting means 12a sends a temperature control signal to a hot air control means 13a so that the rising hot air temperature is equal to heat insulating temperature and counts the time of a residual second process. The hot air control means 13a to which the control signal is input judges the rising hot air temperature from an air temperature judging means 17, compares it with the heat insulating temperature and sends a heating signal based on the comparison value to a heating quantity control means 14. Thus, the heating quantity control means 14 controls the heating quantity of a heater 2 based on the signal so as to have the same value as that of the heat insulating temperature.

(12) is a course setting means having a timer (not shown); a [warm air] course that only dries the futon (9);
It is equipped with an ``automatic fan'' course that blows air to cool the futon (9) after it has been dried. A futon drying time for drying the futon (9) with hot air and an air blowing time for cooling the futon (9) with air are set in advance in the timer. However, the futon drying time can be changed manually.

In addition, the temperature of the hot air while drying the futon can be controlled according to the material of the futon (9). For example, when drying the futon (9),
℃, or 65℃ for cotton using hot air control means (
■Control 3). These temperatures can be adjusted using the operating means described above (
11) Based on the key selection.

(13) is a hot air control means, which operates the heating amount control means (14) and the air blowing control means (15) based on the control signal from the course setting means (12). Further, the heating amount control means (14) is controlled so that the temperature of the hot air determined by the air temperature determination means (17), which will be described later, becomes the same as the temperature set by the course setting means (12). Heating amount control means (14)
is a heater (
2), and the air blowing control means (15) heats the hot air controlling means (15).
The fan (3) is operated based on the operation signal of 18).

In addition, when the above-mentioned temperature exceeds the upper limit temperature, it is due to the backflow of hot air that occurs when the mat (8) is crushed or the hose (7) is clogged with something.

The case where the futon (9) is heated in the conventional futon dryer configured as described above will be explained. Operation means (11
) to select either "feather/wool" or "cotton Δ" operation, then select the "warm air" course with the course setting means (12), and manually set the timer to an appropriate time. , the hot air control means (13) includes a course setting means (
Based on the control signal of step 12), the heating amount control means (14) and the air blowing control means (15) are operated to operate the heater (2) and the fan (3) to generate warm air. Although it varies depending on the room temperature, the temperature of the hot air increases over time until it reaches a predetermined temperature (based on the operation selected by the operating means (11)).
reaches and warms the futon (9). The temperature of the hot air is kept constant by feedback control of the air temperature determining means (17).

At this time, if the time set in the timer of the course setting means (12) expires, the course setting means (12)
) sends a control stop signal to the hot air control means (13) to stop the heater (2) and fan (8).

Therefore, the futon (9) does not get hot but stays warm.

The problem that the C invention aims to solve! ] As mentioned above, conventional futon dryers do not have a function to warm the futon (9), so the "warm air" course setting that dries the futon (9) with warm air can be used to warm the futon (9). I had to. In this case, the user had set the time by intuition to adjust the temperature of the futon (9), but if the user made a mistake in setting the time, the futon (9) may become too hot, or the futon may be heated before it warms up. There was a problem in that the dryer main body (1) sometimes stopped, making it impossible to obtain a comfortable bed temperature.

This invention was made to solve this problem, and an object of the present invention is to provide a futon dryer having a function of automatically warming a futon without relying on the user's intuition.

[Means for Solving the Problems] The futon dryer according to the present invention includes a room temperature detection means for detecting room temperature, and a rising heating time of the room temperature detection means that is inversely proportional to the room temperature, and the heater is heated at a constant temperature. and a control means for controlling the heating amount of the heater so that when the rising heating time is reached, the heating temperature reaches a preset temperature (where the predetermined temperature is greater than the heating temperature). .

[Function] In the present invention, the control means that sets the rise heating time that is inversely proportional to the room temperature of the room temperature detection means heats the heater at a constant heating amount by that time, and then controls the heating amount of the heater. It is controlled to maintain the set temperature.

After the first step, the hot air control means (13a) is operated so that the temperature of the hot air obtained by heating the heater (2) reaches a preset heat retention temperature (for example, 80°C).
(hereinafter referred to as the second step)
.

Note that the time required to warm up the futon (9) is preset in the course setting means (12a), and for example, as shown in FIG. 4, when the room temperature is low, the time for the first step described above is set in advance. Therefore, the time of the second step is set short. Conversely, when the room temperature is high, as shown in FIG. 5, the time for the first step is set short and the time for the second step is set long.

The hot air control means (13a) into which the control signal has been input operates the heating amount control means (14) and the air blowing control means (15) based on the signal. The heating amount control means (14) heats the heater (2) at a constant heating amount, and the air blowing control means (15) operates the fan (3), so warm air is generated and the temperature increases with time. When the temperature of the warm air is rising and the count time reaches the time of the first step, the course setting means (12a) sets the rising temperature of the hot air to the same value as the heat retention temperature. A temperature control signal is sent to the hot air control means (13a), and the remaining time for the second step is counted. Hot air control means (13a) to which this control signal is input
) determines the rising hot air temperature from the air temperature determination means (17), compares it with the heat retention temperature, and sends a heating signal based on the comparison value to the heating amount control means (14).

The heating amount control means (14) controls the heating amount of the heater (2) based on the signal so that it becomes the same value as the heat retention temperature. Then, when the time for the second step is up, the course setting means (12a) starts the hot air control means (13).
