When the outlet 55 is provided to penetrate the first body 51, the water in the chamber C through the outlet 55 is compared to the case where the outlet 55 is provided in the connecting body 53. Since it will be possible to prevent the discharge, the outlet 55 is preferably provided to penetrate the first body (51). The outlet 55 is provided with a steam supply pipe 551 for guiding steam to the clothes receiving portion.

The heater 56 is fixed to the second body 52 and is located outside the chamber C. Therefore, the heat supplied by the heater 56 is transferred to the water inside the chamber C through the second body 52.

Since the above-described steam generator 5 is configured to heat water inside the chamber C through the second body 52 provided as a conductor, all the water supplied to the chamber C can be converted into steam. . Therefore, the steam generator 5 does not require a water level control to maintain the state in which the heater required for the conventional steam generator is submerged in water, and it is possible to minimize the amount of water remaining inside the chamber C and minimize steam. It is possible to minimize the number of water supply to generate.

Looking at the specific structure of the second body 52 with reference to Figure 2, the second body is a heating plate 521 forming the bottom surface of the chamber (C), is provided on the edge of the heating plate of the connecting body A fastening groove 523 in which the free end is accommodated, and a mounting portion 525 provided in the heating plate 521 to provide a space for fixing the heater 56 may be provided.

As illustrated in FIG. 1, an attenuation unit 59 may be further provided inside the chamber C to reduce the fluctuation range of the water level generated inside the chamber C when boiling water.

Since the heater 56 is fixed to the mounting portion 525, the water inside the chamber C boils before the space in which the mounting portion 525 is located is far away from the mounting portion 525. Accordingly, when the water inside the chamber C starts to boil, the water surface inside the chamber C will fluctuate, and in this process, the water may move to the steam supply pipe 551 through the outlet 55. When water is supplied to the clothes through the steam supply pipe 551, there is a problem in that it is difficult to realize effects (smell removal, wrinkle removal, etc.) that can be realized by supplying steam to the clothes. Furthermore, when the water inside the chamber flows into the discharge port 55, there is also a problem that noise is caused.

The damping part 59 is a means for solving this problem. That is, the damping portion 59 provided in the present invention is located between the mounting portion 525 and the outlet 55 to move from the space where the mounting portion 525 is located to the space where the outlet 55 is located Attenuate waves.

The damping part 59 provided in the present invention may be provided as a board protruding from the first body to the second body. In this case, one end of the board is fixed to the first body 51, and the free end of the board should be provided so as not to contact the second body. This is to ensure that water supplied to the supply port 54 is supplied to the mounting portion 525.

It may be provided with a plurality of first board 591 spaced apart from each other. Each of the first boards 591 is fixed to the first body 51 at one end, and the free end does not contact the second body 52.

However, since one first board 591 and the other one board are spaced apart from each other, each of the first board 591 provided in the present embodiment is the first body 51 and the second It may be provided to connect the body 52.

The second attenuation portion 59b may be provided with a plurality of second boards 593 spaced apart from each other along a direction parallel to the first attenuation portion 59a. In this case, the second boards 593 constituting the second attenuator 59b will be positioned between the first attenuator 59a and the outlet 55.

The third attenuator 59c may be provided with a plurality of third boards 595 spaced apart from each other along a direction parallel to the first attenuator 59a.

The space formed between the first boards 591, the space formed between the second boards 593, and the space formed between the third boards 595 are as shown in FIG. 3(a). It may be arranged on a straight line (L1), or may be arranged (L2) staggered with each other as shown in Figure 3 (b).

The shapes of the first board 591, the second board 593, and the third board 595 are divided into a space in which the mounting portion 525 is located and a space in which the outlet 55 is located. It may be provided in a shape parallel to the direction (A) (equipped as a flat plate).

However, as shown in FIG. 4, the shapes of the first board 591, the second board 593 and the third board 595 are convexly bent toward a direction away from the mounting part 525. It may be provided (equipped as a curved plate). When each board 591, 593, 595 is provided in a convex shape toward the direction away from the mounting portion 525, the contact area of each board and water is widened, so that the wave can be attenuated more effectively than the embodiment of FIG. 3.

The embodiment of FIG. 4 also shows a space formed between the first boards 591, a space formed between the second boards 593, and a space formed between the third boards 595. ) May be arranged on a straight line, or may be alternately arranged as shown in FIG. 4(b).

On the other hand, although not shown in the drawing, any one of the three boards 591, 593, and 595 is provided in a convex shape toward a direction away from the mounting part, and the rest of the three boards are equipped with an inside of the chamber C It may be provided in a shape parallel to the direction (A) that divides the space and the space where the outlet is located.

The damping unit 59 provided in the present invention may be provided with only one of the three damping units 59a, 59b, and 59c. In this case, the attenuator 59 is arranged so as to be spaced apart from each other along the direction (A) that divides the interior of the chamber (C) into a space in which the mounting portion 525 is located and a space in which the outlet 55 is located. It can be made of a board.

In addition, each board may be provided with a flat plate parallel to the direction (A) that divides the interior of the chamber (C) into a space in which the mounting portion is located and a space in which the outlet is located, and the direction away from the mounting portion 525 It may be provided with a curved plate convex toward.

The steam generator 5 may further include a water level sensor 57 that senses the water level inside the chamber C, and a temperature sensor 58 that senses the temperature inside the chamber C.

As shown in FIG. 4, the water level sensor 57 is fixed to the connecting body 53 and is a means to prevent the water level inside the chamber C from becoming higher than the outlet 55. That is, the water level sensor 57 is fixed to the connecting body 53 and may be positioned between the second body 52 and the outlet 55.

The water level sensor 57 may be provided as a first electrode 571 and a second electrode 573 fixed to the connection body 53. The first electrode 571 and the second electrode 573 may be provided to be spaced apart from each other along the height direction (direction from the first body to the second body) of the chamber, and the width direction or the length direction of the chamber Accordingly, it may be provided to be spaced apart from each other.

As shown in FIG. 1, when the control unit controls the valve 543 to open the water supply source connection pipe 541, water will be supplied to the chamber C. When the water level inside the chamber (C) rises to the height of the water level sensor (57), the first electrode (571) and the second electrode (573) are electrically connected to each other to control the control signal (control about the water level) Signal), and when the control signal is received from the water level sensor 57, the control unit may control the valve 543 such that the water source connection pipe 541 is closed.

The temperature sensor 58 is fixed to the connecting body 53 and is provided to be positioned between the water level sensor 57 and the second body 52. Therefore, if the water level inside the chamber C is higher than the temperature sensor 58, the temperature sensor 58 measures the temperature of the water, and the water level inside the chamber C is lower than the temperature sensor 58. , The temperature sensor 58 will measure the air temperature inside the chamber.

The heater 56 is provided with an overheating prevention unit (not shown) to prevent overheating of the heater. When the temperature of the heater 56 reaches a preset maximum temperature, the heater is cut off, and the power supplied to the heater is cut off. When the temperature of the heater 56 reaches a predetermined minimum temperature, it may be provided with a fuse that supplies power to the heater again. Therefore, the heater 56 is controlled on-off by the overheating prevention unit.

In the steam generator 5 equipped with the above-described water level sensor 57 and the temperature sensor 58, the heater (in spite of insufficient water supply to the chamber C) due to a failure of the water level sensor 57 56) can be activated. In this case, a fire may occur due to overheating of the heater, and FIG. 5 shows an example of a control method for preventing overheating of the heater by controlling the steam generator 5 with the temperature sensor 58 when the water level sensor 57 fails. It is shown.

In the control method of the present invention, the control unit controls the valve 543 to supply the water to the chamber C through the supply port 54 (S1), and measures the first temperature through the temperature sensor 58. A first measurement step (S10), a heater operation step (S20) for operating the heater 56 after the measurement of the first temperature, and a predetermined first reference time elapsed from the time when the heater 56 starts operating Step S21 of measuring whether the first reference time has elapsed, a second measuring step of measuring a second temperature through the temperature sensor 58 (S30), the second temperature and the second If the difference of 1 temperature is smaller than the first reference value, a heater operation termination step (S80) of stopping the operation of the heater is included.

Since the temperature sensor 58 is fixed to the connecting body 53 and located between the second body 52 and the water level sensor 57, when there is no water inside the chamber C, the water level sensor ( 57), the control signal (control signal about temperature) that the temperature sensor 58 transmits to the control unit tends to be different in each case where water maintains a water level lower than the height of the temperature sensor 58 Will show

That is, since the heater 56 is controlled on-off by the overheating prevention unit, if the heater 56 is operated without water in the chamber C, the on-off period of the heater will be shortened. When the on-off period of the heater is short, there will be almost no heat supply into the chamber, so there will be almost no temperature change inside the chamber C measured by the temperature sensor 58.

Alternatively, when there is water in the chamber C, the temperature measured by the temperature sensor 58 will tend to increase to 100 degrees Celsius. Therefore, when comparing the temperature change after the first reference time after the electric power is supplied to the heater 56, it is possible to determine whether there is water or no water in the chamber C.

Therefore, the difference between the first temperature measured before the start of the heater operation step is compared with the first reference value at the second temperature measured when the first reference time has elapsed after the start of the heater operation step (S20) (S31). If it does, it may be possible to determine whether water is stored in the chamber C or water is not in the chamber C.

In order to prevent a safety accident due to overheating of the heater, the shorter the first reference time is, the more advantageous it is. According to an experiment, the first reference time is set to a time of 1 minute or more and 2 minutes or less, and the first When the reference value was set to 15 degrees Celsius, it was confirmed that the case with and without water in the chamber can be effectively distinguished.

If it is determined that the difference between the second temperature and the first temperature is smaller than the first reference value, it can be seen that there is no water in the chamber (C), so the control method of the present invention is to terminate the heater operation step (S80). To proceed. Therefore, the present invention can solve the problem caused by the operation of the heater 56 even though there is no water inside the chamber C due to the failure of the water level sensor 57.

In the control method of the present invention, an error display step (S70) of displaying an abnormality of the steam generator 5 on the display unit 17 may be performed before the heater operation end step (S80). The information displayed on the display unit 17 may be a text or audio signal that requests a user to inspect the steam generator 5.

On the other hand, if it is determined that the difference between the second temperature and the first temperature is greater than or equal to the first reference value, the control method of the present invention is a third measurement step (S40) of periodically measuring the third temperature through the temperature sensor 58 , Determining whether or not the third temperature measured in the third measurement step (S40) has reached a preset reference temperature (S41), a second reference time preset from when the third temperature reaches the reference temperature Determining whether or not this has elapsed (S43), a fourth measuring step (S50) of measuring the fourth temperature through the temperature sensor 58 when the third temperature reaches the reference temperature, the fourth temperature and the Step S51 of determining whether the difference between the third temperature (reference temperature) is equal to or greater than a preset second reference value (S51).

Even when water is stored in the chamber C, the control signals transmitted from the temperature sensor to the control unit show different trends depending on the amount of water. That is, it takes a short time to reach the boiling point (100 degrees seed) when the chamber C has little water compared to the case where there is much water. This means that the rate of temperature change when the amount of water is small is larger than the rate of temperature change when the amount of water is large.

Therefore, if the value obtained by subtracting the third temperature from the fourth temperature is greater than or equal to the second reference value, the control method of the present invention determines that less water is stored in the chamber C, and the third temperature is the fourth temperature. If the value minus is less than the second reference value, the control method of the present invention can be judged to be full of water stored in the chamber C.

According to the experiment, when the reference temperature is set to 80 degrees C, and the second reference time is set to a time of 10 seconds or more and 30 seconds or less, it was confirmed that the amount of water inside the chamber C can be effectively classified. In addition, the second reference value may be set to the same value as the first reference value, or may be set to a different value. In FIG. 5, the second reference value is the same as the first reference value (15 degrees C). The case where the value is set is illustrated as an example.

If the value obtained by subtracting the third temperature from the fourth temperature is greater than or equal to the second reference value, the control method of the present invention sequentially performs an error display step (S70) and a heater operation end step (S80).

On the other hand, if the value obtained by subtracting the third temperature from the fourth temperature is less than the second reference value, the control method of the present invention is a fifth measurement step (S60) for measuring the temperature (the fifth temperature) inside the chamber (C). ), a step (S61) of determining whether the fifth temperature measured through the fifth measurement step is less than a preset termination reference temperature. The termination reference temperature may be set to a temperature of 20 degrees C or more and 40 degrees C or less.
