DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the structure of a breast conditioner.

[0002]

2. Description of the Related Art Conventionally, for example, milk preparation for an infant is
A method has been adopted in which hot water kept warm after being boiled in an electric pot or the like is put into a baby bottle, cooled to a predetermined temperature, and used.

[0003]

However, it is very difficult to pour hot water from the hot water supply port of the electric kettle into the baby bottle. In addition, it is very difficult for the user to accurately determine whether the temperature of the hot water in the baby bottle has cooled to a desired temperature. That is the fact. So sometimes it ’s too hot,
There was a problem that was too warm.

The present invention has been made in order to solve such a conventional problem. After the boiling water is heated, the temperature of the hot water is relatively quickly cooled to an accurate set temperature, and the temperature is kept at the accurate set temperature. It is an object of the present invention to provide a milk-supplying pot server-type milking machine that can be performed.

[0005]

Means for Solving the Problems lang = EN-US> The present invention is provided with the following problem solving means in order to solve the above-mentioned conventional problems and effectively achieve the object. .

That is, in the present invention, a heater plate having a milking pot mounting surface for mounting a milking pot is provided on a case body, and the heater plate is brought into contact with the bottom surface of the milking pot. Providing a temperature sensor for detecting the temperature, and providing a heat shield plate for shielding heat downward, the heat shield plate is formed in a dish-like structure of a predetermined depth as a whole,
The case body has an upper opening formed with a side wall surrounding the outer periphery of the heater plate at a position above the opening edge by engaging with an opening edge of a side wall in the dish-shaped structure of the heat shield plate. The side wall formed at the upper opening of the case body and the side wall of the heat shield plate cover the outer periphery of the bottom of the milk preparation pot placed on the milk preparation pot mounting surface of the heater plate. It is characterized in that the heat from the heater does not escape to the surroundings.

[0007] In this configuration, the heat shield plate is formed in a dish-like structure having a predetermined depth as a whole, and the case portion main body is provided at an upper opening portion with a side wall portion in the dish-like structure of the heat shield plate. The side wall surrounding the outer periphery of the heater plate is formed at a position above the opening edge by engaging with the opening edge, and the side wall formed at the upper side opening of the case body and the side wall of the heat shield plate respectively. Since the heat from the heater is configured to cover the outer periphery of the bottom portion of the milking pot placed on the milking pot mounting surface of the heater plate so as not to escape to the surroundings,
The bottom surface of the milk preparation pot is properly placed in a stable state corresponding to the surface on which the milk preparation pot is placed on the heater plate without the milk preparation pot coming off the heater plate.

As a result, when the bottom surface of the milking pot properly corresponds to the heater plate and the heater of the heater plate is energized, the heat from the heater does not escape to the surroundings and the heater plate passes through the heater plate. The heat is efficiently transmitted to the milk-supplying pot placed on the milk-supplying pot mounting surface, and water heating with high thermal efficiency is performed.

[0009] The temperature of the hot water in the milk preparation pot which rises due to the boiling water is also accurately detected by the temperature sensor of the heater plate in contact with the bottom surface of the milk preparation pot without being affected by the outside air. . Then, when the detected value becomes a value indicating the state of boiling water, the state is determined by, for example, a microcomputer, and the power supply to the heater is stopped.

[0010] When the power supply to the heater is stopped, the milk preparation pot has a high cooling performance because the whole except the outer periphery of the bottom is exposed to the outside air as described above.
The temperature of the hot water rapidly decreases due to the heat radiation to the outside air. The decrease in the temperature of the hot water is also affected by the outside air, as described above, which is located on the bottom side of the milk preparation pot and is surrounded by the side wall of the heat shield plate and the upper side opening of the case body. The temperature is accurately detected by the above temperature sensor. Here, it is important not to be affected by the outside air temperature. For example, when the heater section and the temperature sensor section are opened to the outside in the horizontal direction as in a general coffee pot server heater, the actual hot water is not affected by the outside air. A temperature considerably lower than the temperature is detected. As a result, there is a possibility that a hot water state considerably higher than the set temperature desired by the user may be detected as the set temperature. However, such a fear does not occur in the configuration of the present invention.

On the basis of the N signal, the power supply circuit of the above-mentioned breast conditioner control circuit is controlled so that the above-mentioned sheath heater 21 can be energized. On the other hand, the milking pot 50 is removed and the upper sensing surface 35b of the sensor cylinder 35 is
2. When the limit switch 46 is protruded from the upper surface by a predetermined height, the intermediate support member 37 is also raised, and the operating lever 46a is returned to the upper position, the limit switch 46 is OFF. 21
The power supply circuit of the above-mentioned formula controller control circuit is controlled so as to be in a state in which power cannot be supplied to the breast-conditioner.

Therefore, in this embodiment, the temperature sensor 2
5 performs an empty detection operation of the milk preparation pot 50 together with a hot water temperature detection operation of detecting the temperature of the hot water in the milk preparation pot 50,
When the empty state is detected, the power supply to the sheath heater 21 is cut off, so that safe and unnecessary power consumption is eliminated.

On the other hand, the milk preparation pot 50 is made of a transparent heat-resistant glass material and has a bottle-like shape having a large diameter at the center in the vertical direction and small diameters at both upper and lower ends as shown in the figure. The bottom portion 50a is formed in a loose concave round surface corresponding to the loose convex round surface on the upper surface of the heater plate 22, and the upper end portion is formed in a cylindrical shape in which a beak-shaped pouring port 51 is formed on the front side. It is formed in the opening 50b. And
The handle 60 is fitted and fixed using the base of the opening 50b, and a lid 70 made of a transparent heat-resistant glass material is detachably fitted to the upper part of the opening 50b. ing. The lid 70 has an engaging edge 7 that engages with the inside of the rim of the opening 50b on the side of the milking pot 50.
1 is formed so as to protrude downward, and a part 71a of a front side portion thereof protrudes further downward so as to be fitted in the pouring port 51 densely. It is designed to close.

Therefore, in the breast-conditioning apparatus having the above configuration, a predetermined amount of water W is injected into the above-mentioned breast-conditioning apparatus 50, and the power plug is
1 on the heater plate 22 in a state of being inserted into the power outlet, the sensor cylinder 35 of the temperature sensor 25 and the intermediate support member 37 are lowered at the time of mounting, and Switch 46
Is turned ON, and the above-described milking controller control circuit centered on the microcomputer 29 operates to start energization of the sheath heater 21. Then, the seed heater 21 uniformly heats the entire bottom surface 50a of the milk preparation pot 50 via the heater plate 22, thereby performing water heating with high thermal efficiency.

By the way, in the above configuration, the heater plate 22 having the milking pot mounting surface on which the milking pot 50 is mounted is provided.
Is provided on the case body 10 while the heater plate 2
2 is provided with a temperature sensor 25 for detecting the temperature by contacting the bottom surface of the milk preparation pot 50, and a heat shield plate 19 for shielding heat downward, and the heat shield plate 19 has a side wall portion. Is positioned above the milk preparation pot mounting surface from the outer peripheral edge of the heater plate 22 to form an upwardly inclined surface, and is mounted on the milk preparation pot mounting surface of the heater plate 22. Since the bottom outer periphery of the milk preparation pot 50 is configured to be covered, the heat shield plate 19 realizes a heat shielding action to the side of the upper opening 2 a of the case portion main body 10 and the heat shield plate 19. The bottom surface of the milk-supplying pot 50 can be appropriately adjusted without the milk-supplying pot 50 coming off the surface of the heater-pot mounting surface of the heater plate 22 by the guide action of the upward slope of the side wall.
Is placed in a stable state corresponding to the surface of the milk preparation pot, which facilitates the placement. In addition, heat is efficiently transmitted to the milk preparation pot 50 placed on the heater plate 22, and the water heater with high thermal efficiency is performed.

The rise in the temperature of the hot water in the milk preparation pot 50 in the boiling state is accurately detected by the thermistor 34 of the temperature sensor 25, and is input to and read from the microcomputer 29 at a predetermined cycle.
When the reading temperature reaches a temperature indicating a boiling state, the microcomputer 29 determines the state, stops energization of the sheathed heater 21, and starts cooling control. In the cooling control state, the sheath heater 21 is turned off.
Only the detection signal of the thermistor 34 is input as F, and the decrease of the hot water temperature in the milk preparation pot 50 is monitored.

In the case of the breast conditioner of this embodiment, the case body 10 has a single wall structure as described above, and the case body 10 is attached to the upper side opening 2a of the upper case 2 by the heat shield plate. 19, a side wall surrounding the outer periphery of the heater plate 22 is formed at a position above the opening edge of the side wall portion, and the upper side opening 2 of the upper case 2 in the case body 10 is formed.
The side wall formed at a and the side wall of the heat shield plate 19 cover the outer periphery of the bottom of the milk preparation pot placed on the milk preparation pot mounting surface of the heater plate 22. The side wall of the upper opening 2a surrounding the outer periphery of the heater plate 22 has a low waist (height) and is designed to surround only the outer peripheral portion at the bottom of the milk preparation pot 50. The degree of cooling by the heat radiation of the pot 50 to the outside air is high, and the temperature of the hot water rapidly decreases. The decrease in the temperature of the hot water is caused by the side wall of the upper side opening 2a of the case main body 10 and the side wall of the heat shield plate 19, as described above. Thermistor 3 of the temperature sensor 25 that is surrounded and is not affected by outside air.
4 accurately detected. Here, it is important not to be affected by the outside air temperature. For example, when the heater section and the temperature sensor section are opened to the outside in the horizontal direction as in a general coffee pot server heater, the actual hot water is not affected by the outside air. A temperature considerably lower than the temperature is detected. As a result, there is a fear that a hot water state considerably higher than the set temperature desired by the user may be detected as the set temperature.
Such fear does not arise.

Then, as a result of the cooling control being continued in this manner, the hot water temperature detected by the thermistor 34 is changed to the hot water temperature selected and set by the warming temperature selection button 11 (the first set temperature of 60 ° C. or 60 ° C.). Second set temperature 9
0 ° C) at the same time.
Numeral 9 turns ON / OFF the sheathed heater 21 at a duty ratio suitable for maintaining the heat retaining temperature, and executes the heat retaining control at the set temperature.

As a result, the user can always freely obtain hot water at the above-mentioned heat retaining temperature set by the user, and
The beaker-shaped pouring port 51 of the milking pot 50 having the above can be used to easily pour a baby bottle.

As a result, according to the above-structured milk conditioner, it is easy to boil water with high heat efficiency up to boiling and high heat efficiency, and quickly and accurately cool water to a desired set temperature after completion of boiling. In addition, it is possible to provide a warming pot server-type milking machine capable of keeping heat.

Further, the milk conditioner can be used for purposes other than milk preparation, such as coffee, black tea, and green tea, for example, by allowing a plurality of types of the set temperatures to be set. Get higher.

In the above configuration, the ON / OFF duty of the sheathed heater 21 is changed during the heat retention control. For example, a separate heat retention heater corresponding to the set temperature is provided, and the heat retention heater is energized. You may do it.

(Embodiment 2) Next, FIG. 4 shows the configuration of a breast conditioner according to Embodiment 2 of the present invention.

In the milking apparatus of the present embodiment, the structure of the milking apparatus of the first embodiment is slightly changed in the structure for detecting the emptying of the milking pot of the temperature sensor 25, and a waterproof measure is provided on the microcomputer board 16. With a milking pot 50
The limit switch 46 that detects the empty state of the temperature sensor is changed from a lever type to a rod type that vertically turns ON and OFF, and is turned ON and OFF at the lower end of the cylindrical portion 37b of the temperature sensor intermediate support member 37. And the microcomputer board 16 is attached to the board cover 8.
0, and the substrate cover 8
A seal case 84 is provided at the fitting portion of the 0 cylindrical portion 37b through a seal packing 81 for sealing.

That is, in this configuration, the small-diameter cylindrical portion 37 on the lower side of the intermediate support member 37 in the configuration of the first embodiment is used.
Lead wires 39a and 39b are drawn out from the lower end side of b, and the microcomputer board 16 is arranged below the lead wires 39a and 39b. Then, the ON / OFF rod 46b of the limit switch 46 is installed facing the upper side on the microcomputer board 16 below the cylindrical portion 37b of the intermediate support member 37 as shown in the figure.

On the other hand, the microcomputer board 16
A substrate cover 80 is crowned on the upper part of the upper part, and the cylindrical portion 37b penetrates the substrate cover 80 slidably up and down to face the ON / OFF rod 46b of the limit switch 46 as described above. A sleeve-shaped seal case 84 is provided on the cylindrical portion through hole 82 of the substrate cover 80.
To form On the other hand, a flange-like packing 85 having a lip portion 85a on the outer periphery is fitted and fixed to the outer periphery of the corresponding cylindrical portion 37b, and a sealing state is realized between the inner wall of the seal case 84 via the packing 85. .

In this manner, as in the case of the first embodiment, when the milk preparation pot 50 is not placed on the heater plate 22, the sensor cylinder 35 and the intermediate support member 37 are not placed.
Is raised, and the lower end of the cylindrical portion 37b of the intermediate support member 37 is turned ON and OFF of the limit switch 46.
Since the limit switch 46 is located above the rod 46b, the limit switch 46 generates an OFF output. And
The microcomputer 29 determines that there is no milk preparation pot 50 based on the OFF output, and controls the power supply circuit so as to cut off the power supply to the sheathed heater 21.

On the other hand, when the milk preparation pot 50 is placed on the heater plate 22, the sensor cylinder 35 and the intermediate support member 37 are lowered, and the lower end of the cylindrical portion 37b is set to the ON / OFF rod of the limit switch 46. 46b is pressed downward. As a result, the limit switch 46 is turned on. Accordingly, the microcomputer 29 determines that the milk preparation pot 50 has been placed on the heater plate 22 based on the ON output of the limit switch 46, and supplies a power supply circuit so that the sheath heater 21 can be energized. Control.

As a result, according to the above-described first embodiment,
In the same manner as in the case (1), power supply control to the sheath heater 21 according to the presence or absence of the milk preparation pot 50 becomes possible, and safety and energy saving effects can be obtained.

In addition, in the case of this configuration, the microcomputer board 16 is covered by the board cover 80 as described above, and the cylindrical portion 37 of the board cover 80 is formed.
Since the b insertion hole 82 is sealed by the seal case 84 and the packing 85 so as to be able to move up and down, the water does not enter the microcomputer board 16 even when water enters the temperature sensor 25.

The other constructions and the functions and effects corresponding thereto are completely the same as those of the first embodiment in this embodiment.

(Embodiment 3) Next, FIG. 5 shows the configuration of a breast conditioner according to Embodiment 3 of the present invention.

In the present embodiment, the milking pot empty detecting structure of the temperature sensor 25 in the configuration of the milking apparatus of the first embodiment is changed. Light emitting element 62 and light receiving element 63

That is, in this configuration, the small-diameter cylindrical portion 37 on the lower side of the intermediate support member 37 in the configuration of the first embodiment is used.
While pulling out the lead wires 39a and 39b from the middle of b,
A flat portion A having a predetermined width is formed on the lower side. Then, the light emitting element 62 and the light receiving element 63 are installed on both sides of the flat part A lowered position on the microcomputer board 16 extending part 16a below the intermediate support member 37 so as to face each other as shown in the figure.

Because it will be located above the optical axis between the three,
Light from the light emitting element 62 is input to the light receiving element 63, and the light receiving element 63 generates a voltage output (ON output) of a predetermined level. Then, the microcomputer 29 determines that the milking pot 50 does not exist based on the voltage output, and controls the power supply circuit so as to cut off the power supply to the sheathed heater 21. At this time, some kind of alarm sound may be generated as necessary.

On the other hand, when the milk preparation pot 50 is placed on the heater plate 22, the sensor cylinder 35 and the intermediate support member 37 are lowered, and the flat portion A shields light from the light emitting element 62. As a result, the voltage output from the light receiving element 63 is turned off. Therefore, the microcomputer 2
9 determines that the milking pot 50 is placed on the heater plate 22 based on the OFF of the voltage output, and controls the power supply circuit so that the sheath heater 21 can be energized.

As a result, according to the configuration of the first embodiment,

In the milking apparatus of this embodiment, the structure of the milking apparatus of the first embodiment is different from that of the milking pot of the temperature sensor 25 in that the emptying of the milking pot 50 is detected by the limit switch 46. Instead, the detection is performed by a magnet (magnetic) coupler structure in which a magnet 87 and a reed switch 88 are vertically opposed.

That is, in this configuration, the lead wires 39a, 39b are inserted from the middle of the small-diameter cylindrical portion 37b on the lower side of the intermediate support member 37 similar to the intermediate support member in the configuration of the first embodiment.

(Embodiment 5) FIG. 7 shows a configuration of a temperature sensor section of a breast adjuster according to Embodiment 5 of the present invention.

Lang = EN-US> In the milking pot empty detecting structure of the temperature sensor 25 in the milking machines of the first to fourth embodiments, for example, the limit switch 46
A detecting unit and a detecting means having a detecting function different from that of the thermistor 34, such as a photo coupler unit (light emitting element 62, light receiving element 63) and a magnet coupler unit (magnet 87, magnetic reed switch 82) are required. For this reason, disadvantages arise in terms of the number of components, component costs, and wiring costs. In addition, there is a problem that the arrangement space is largely restricted and the space factor is inferior.

Therefore, in the present embodiment, such a separate detection function is not required, and only the temperature detection function of the thermistor 34 is utilized so that the hot water temperature detection can detect the emptyness of the milk preparation pot 50 from the start. It is characterized by doing.

That is, in this embodiment, as shown in the figure, the above-described sensor cylinder 35 is a multi-diameter cylinder having a chevron-shaped cross section composed of a small-diameter portion 35e and a large-diameter portion 35d whose diameter is gradually increased stepwise from above to below. The lower opening edge portion 35c is formed to have a predetermined width in the form of a flange outward in the horizontal direction.

The inside of the large diameter portion 35d is supported by an intermediate support member 57 urged upward by a coil spring 56 in the same manner as the above-described intermediate support member 37, thereby being supported so as to be able to move up and down. In the case of the present embodiment, the coil spring 56 is supported on the heat shield plate 19 by providing an engaging portion 58 thereon.

Therefore, in this configuration, as in the two embodiments described above, when the milk preparation pot 50 is not placed on the heater plate 22, the sensor cylinder 35 is biased by the coil spring 56. Upper small diameter part 3 of
The upper end sensing surface 35b of 5e protrudes from the upper surface of the heater plate 22 by a predetermined height, and the lower opening edge 35c is in contact with the lower surface 22b of the heater plate 22 as a stopper piece.

Therefore, in this state, if the power plug is inserted into the AC power outlet, the heat itself from the heater plate 22 is very quickly and satisfactorily transmitted to the thermistor 34 via the sensor cylinder 35, and the thermistor 34 Detects a temperature much higher than the hot water temperature of the milk preparation pot 50 accurately and quickly and inputs it to the microcomputer 29.

Then, the microcomputer 29 determines that the power supply is idle based on the input temperature value, generates an alarm, and further opens the open / close switch of the power supply circuit to supply power to the sheathed heater 21 side. To cut.

On the other hand, when the milk preparation pot 50 is placed on the heater plate 22, the sensor cylinder 35 descends, so that the lower opening edge 35c and the heater plate 22 are moved downward.
The sensing surface 35b at the upper end of the upper small-diameter portion 35e is separated from the lower surface 22b, and does not receive heat conduction from the heater plate 22. Therefore, the detected temperature value is lower than that in the above case, and the microcomputer 29 can accurately determine that the milk preparation pot 50 is placed on the basis of the detected temperature value, and can energize the open / close switch of the power supply circuit. To accurately detect the temperature of the bottom surface 50a of the milk preparation pot 50.

As described above, even with the configuration of this embodiment, it is possible to accurately detect the emptying of the milk preparation pot 50 substantially in the same manner as in the first to fourth embodiments.

In the present embodiment, the other structures, functions and effects are the same as those of the first embodiment.

(Embodiment 6) FIG. 8 shows the configuration of a breast conditioner according to Embodiment 6 of the present invention.

According to the configuration of the fifth embodiment shown in FIG. 7 as described above, empty detection of a milking pot can be performed only by the thermistor 24, so that the structure of the sensor unit is simple and low-cost, and the layout is also easy. .

However, in this configuration, since the sensor cylinder 35 itself is supported via the intermediate support member 57 which is also a guide member, the number of parts is still large.

Therefore, the present embodiment is characterized in that such an intermediate supporting member 57 is not required, and the ascending / descending operation can be performed by utilizing the large diameter portion 35d of the sensor cylinder 35 and the heat shield plate 19. I have.

That is, in the present embodiment, as shown in the drawing, similarly to the fifth embodiment, the above-described sensor cylinder 35 is gradually reduced in diameter from the upper side to the lower side in a small diameter portion 35e.
And a large-diameter section 35d and a multi-diameter cylindrical body having a mountain-shaped cross section, and the lower opening edge 35c is formed to have a predetermined width in the form of a flange outward in the horizontal direction. The large-diameter portion 35d is formed particularly long downward.

On the other hand, in the case of the present embodiment, the heat shield plate 19 supporting the lower end of the coil spring 56 is
The lower opening edge 35c of 5d is formed in the lower deep cylindrical portion 19a which can be loosely fitted, and the lower end side engaging portion (convex portion) 58 of the coil spring 56 is provided at the center of the bottom of the cylindrical portion 19a. It is configured.

The large diameter portion 35d of the sensor cylinder 35
The lower opening edge 35c is fitted inside the cylindrical body 19a so as to be able to move up and down, and is supported in the same manner as the above-described intermediate support member 37 while being biased and supported upward by the coil spring 56. It is supported to be able to move up and down.

Therefore, in this configuration, the milk preparation pot 5 is placed on the heater plate 22 as in the above-described embodiments.
0 is not placed, the coil spring 56
Of the sensor cylinder 35 due to the urging force of
The upper end side sensing surface 35b of the upper part projects from the upper surface of the heater plate 22 by a predetermined height.
The shoulder 89 of 5d is in contact with the hook-shaped engagement surface 90 of the opening of the heater plate 22 as a stopper surface.

Therefore, in this state, if the power plug is inserted into the AC power outlet, the heat itself from the heater plate 22 is very quickly and satisfactorily transmitted to the thermistor 34 via the sensor cylinder 35, and the thermistor 34 Detects a temperature much higher than the hot water temperature of the milk preparation pot 50 accurately and quickly and inputs it to the microcomputer 29.

Then, the microcomputer 29 determines that the power supply is idling based on the input temperature value and generates an alarm, and further opens the open / close switch of the power supply circuit to supply power to the sheathed heater 21 side. To cut.

On the other hand, when the milk preparation pot 50 is placed on the heater plate 22, the sensor cylinder 35 descends, so that the shoulder 89 of the large diameter portion 35d and the heater plate 2
The two engagement surfaces 90 are separated from each other, and the sensing surface 35b at the upper end of the upper small-diameter portion 35e does not receive heat conduction from the heater plate 22. Therefore, the detected temperature value is lower than in the above case, and the microcomputer 29 calculates the temperature value from the detected temperature value.
Accurately determines that the milking pot 50 is placed, and closes the open / close switch of the power supply circuit so as to be able to conduct electricity to accurately detect the temperature of the bottom surface 50a of the milking pot 50.

As described above, even with the configuration of this embodiment, it is possible to accurately detect the emptying of the milk preparation pot 50 substantially as in the first and second embodiments.

In the present embodiment, the other structures, functions and effects are the same as those of the first embodiment.

Thus, an operation panel section is formed.

However, with this configuration, the structure is complicated and the number of parts increases.

Therefore, in this embodiment, as shown in FIG. 9, for example, the case body 10 is formed by the lower case 1 and the upper case 2, and the lower case 1 is formed by the peripheral wall 100 and the bottom plate 5. While the control board cover 101 is integrally molded inside the upper case 2, the operation panel installation portion 100a of the peripheral wall 100 is cut out. On the other hand, the operation panel board 102 is integrally formed in a hook shape on the corresponding front side portion of the bottom plate 5 in an upright state. Then, by forming a slit-shaped cutout 103 in the operation panel substrate 102, a pressing operation piece 104 such as a switch, which is vertically long and elastically deformable in the front-rear direction, as shown, is formed.

When the operation panel board 102 is in the assembled state, the operation panel installation section 10 of the cut-out peripheral wall 100 is
10 is fitted as shown in FIG. 10, and a microcomputer board 16 provided with a corresponding ON / OFF switch 105 is mounted behind the board via the board cover 101 of the upper case 2. Then, the operation panel substrate 102
A switch sheet 106 is finally attached to the front side of the switch.

With this configuration, the structure is simplified, the number of parts is reduced, and the assembly is facilitated. Further, for example, even if the upper case 2 and the peripheral wall 100 are molded from a low-cost synthetic resin such as polyethylene terephthalate (PET), at least the bottom plate 5 has high rigidity,
In addition, sufficient durability can be ensured only by molding with a durable synthetic resin such as polypropylene (PP).
