Description

  The present invention relates to a boiled noodle machine that boiles noodles such as udon, ramen, and spaghetti in a restaurant or a restaurant. In particular, the present invention relates to a boiled noodle machine that can automatically boil noodles provided to a large number of people with limited power (energy supply).

  Boiled noodle machines are installed in restaurants and restaurants such as udon, ramen and spaghetti. The boiled noodle machine is equipped with a large hot water storage tank capable of immersing a plurality of noodle baskets and a heat source such as a gas burner or an electric heater for boiling the hot water in the tank. The noodles are boiled in the noodle basket while being stirred by the boiling power of hot water. The boiling force is the momentum of a water flow in which a lot of bubbles are generated when the water is boiled, and has a function of boiling while stirring so that the noodles do not become lumps.

  A typical noodle basket with six typical electric heater-type boiled noodle machines has a hot water tank capacity of about 48-50 liters, and its power consumption is applied to general commercial kitchens. The maximum value is 9 kW / h for the device to be used. In addition, when noodles are spaghetti, since the noodles are long, the depth of the noodle basket is deepened, and the capacity of the hot water storage tank is increased to about 64 liters accordingly. In restaurants and canteens, orders are concentrated during lunch and dinner, so there is a demand for handling as many orders as possible in a short time. When the number of noodle baskets is 12 baskets, which is twice the current number, with a conventional boiled noodle machine, the hot water storage tank has a capacity of about 100 liters, and it is difficult to obtain sufficient boiling power with the current power. is there.

  In order to boil large quantities of noodles well with limited power, all noodle baskets can be made by increasing the thermal efficiency by reducing the capacity of the hot water tank or by concentrating the heating power of the heater efficiently on the noodles. It is necessary to apply a uniform and sufficient boiling force to the surface.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a boiled noodle machine that is semi- sealed and that generates a small amount of steam and can be operated automatically.

A boiled noodle machine related to the present invention is a boiled noodle machine that boiles noodles in hot water, comprising a hot water storage tank for storing the hot water, and means for moving the noodle basket in the hot water storage tank, and the hot water storage tank Has a substantially cylindrical outer peripheral wall and a cylindrical boss erected in the center of the tank, and the noodle basket moving means rotates the noodle basket around the central axis of the hot water tank. The outer periphery of the said boss | hub is formed in the magnitude | size which protrudes to the vicinity of the rotation locus | trajectory inside the said noodle basket.

By providing the boss in the hot water tank, the capacity of the hot water tank can be reduced. At this time, the capacity of the hot water tank can be reduced to the minimum by increasing the diameter of the boss as much as possible. For this reason, the boiling power of hot water for loosening boiled noodles can be ensured even within limited power.
The clearance between the outer periphery of the boss and the inner rotation locus of the noodle basket is preferably 3 to 6 mm, and the clearance between the outer wall of the hot water tank and the outer rotation locus of the noodle basket is preferably 3 to 6 mm.

Furthermore, it is preferable that a boiling flow guide having a downward tapered shape is provided on the outer surface of the bottom of the noodle basket.
By making the bottom shape of the noodle basket into a round shape, there is no corner at the bottom of the noodle basket where the noodles tend to clump. Further, by providing the boiling flow guide, the boiling flow can be concentrated on the bottom of the noodle basket. This type of noodle basket is suitable for boiling spaghetti dry noodles (having a length of about 260 mm).

Another boiled noodle machine related to the present invention is a boiled noodle machine for boiling noodles in hot water, a hot water storage tank for storing the hot water, means for moving the noodle basket in the hot water storage tank, A plurality of heaters arranged at the bottom of the hot water storage tank along a movement path, and boiling that is disposed on the heater and intensively applies the boiling flow formed by the heater to the center of the bottom of the noodle basket The noodle basket moving means is intermittently operated so as to stop the noodle basket on the heater.
In this boiled noodle machine , the heater is placed directly in the hot water on the bottom of the hot water tank, and a boiling outlet is formed at the center of the boiling flow concentrating plate. It can be located on the center of the heater.

  Since the noodle basket moves while stopping on the heater, the heating power of the heater can be concentrated on the noodle basket. Moreover, if the time for each noodle basket to stay on the heater is made constant, a uniform heating force can be applied to each noodle basket. Furthermore, by having a boiling flow concentration plate, the boiling power of the heater can be concentrated by the noodle basket.

  In the above invention, if the water-steam heat exchanger for exchanging the steam generated in the hot water storage tank with tap water is provided, the steam generated from the hot water storage tank can be recovered with high efficiency. In this case, the deterioration of the environment of the kitchen with the boiled noodle machine can be suppressed, and a reduction in power consumption of the air conditioner can also be expected.

In noodle machine in other boiled present invention, before Kisui - steam heat exchanger, said being a plurality of stages arranged in the exhaust passage, the water - steam heat exchanger, tap water is passed through the interior It is preferable that the flow direction of tap water passed through the pipe and the flow direction of exhaust gas led to the exhaust passage are opposed to each other.
By providing a plurality of water-steam heat exchangers, the steam recovery rate can be further increased. Moreover, the temperature of the tap water coming out of the heat exchanger is set by making the flow direction of the tap water passed through the pipe of the water-steam heat exchanger and the flow direction of the exhaust gas led to the exhaust passage opposite to each other. The tap water can be effectively used such as hot water being poured into a hot water storage tank, and the heat energy of the exhaust can be recovered.

Another boiled noodle machine related to the present invention is a boiled noodle machine that boiles noodles in hot water, comprising a hot water storage tank for storing the hot water, and means for moving the noodle basket in the hot water tank, The hot water storage tank has a substantially cylindrical outer peripheral wall and a cylindrical boss erected at the center of the tank, and the noodle basket moving means moves the noodle basket around the central axis of the hot water storage tank. The noodle basket has a polygonal cross-sectional shape.

  Here, the polygon has, for example, the outer peripheral wall of the hot water tank and the substantially parallel sides along the outer peripheral wall of the boss, the outer peripheral wall of the hot water tank is the outer peripheral circle, and the outer peripheral wall of the boss is the inner peripheral circle. It is preferable that the annular portion to be formed has a shape as close as possible to a fan-shaped shape defined by two sides extending in the radial direction from the centers of the hot water tank and the boss. When the circumferential pitch of the hot water tank or the boss is the same, the cross-sectional area (in the horizontal cross section) of the noodle basket can be made larger than when the cross-sectional shape is circular. That is, the internal volume of the noodle basket can be increased. Therefore, the amount of noodles that can be processed can be increased without increasing the capacity of the hot water tank.

Alternatively, the height of the noodle basket can be reduced by increasing the cross-sectional area. Also in this case, the amount of noodles that can be processed can be increased without increasing the capacity of the hot water tank.
Or conversely, the capacity of the hot water tank can be reduced without reducing the amount of noodles that can be processed.

It has a rotation mechanism which rotates a basket around the central axis of the hot water storage tank, and the discharge means has a mechanism which reverses the noodle basket on the rotation mechanism.

  Since there is no need to provide a special mechanism for lifting the noodle basket, the mechanism of the dispensing means can be simplified. In addition, there may be a subordinate lift operation that slightly raises the noodle basket as it rotates.

In the boiled noodle machine, the noodle basket includes a basket body and a noodle discharging guide extending upward from an outer side of the basket body, and the noodle discharging guide is located outside the basket body. A rotating fulcrum placed on the noodle basket rotating mechanism, and a force point located outside the rotating fulcrum, and the payout means has a noodle basket reversing actuator, An actuator pushes down the force point of the noodle basket to rotate the noodle basket around the rotation fulcrum, lifts the basket main body up, and discharges the noodle from the basket main body through the noodle discharge guide; it can.
Here, the speed of the reversing actuator is preferably variable. If the speed of reversing the basket is increased, the amount of boiled broth for the noodles to be discharged increases. Depending on the type of noodles and dishes, the broth is useful for preventing the noodles from drying and improving the flavor.

  Since the noodle basket is rotated around the rotation fulcrum on the noodle basket rotating mechanism, the noodle basket can be reversed without being lifted as much as possible from the rotating mechanism.

In the present invention, the reversing actuator has two vertical bars movable up and down on both sides of the noodle discharge guide, and a horizontal bar extending between the lower ends of the vertical bars. The two vertical bars are lowered, the horizontal bar is lowered to the lower side of the noodle basket while pushing down the power point of the noodle basket, and the noodle guide of the noodle basket passes between the two vertical bars. It can be turned outward.
When the noodle basket is reversed, each member of the reversing actuator does not interfere with the noodle dispensing operation. For this reason, noodles can be smoothly discharged from the noodle basket.

BEST MODE FOR CARRYING OUT THE INVENTION

  Hereinafter, it demonstrates, referring drawings.

First embodiment

FIG. 1 is a front view showing the structure of a boiled noodle machine according to the first embodiment of the present invention.
FIG. 2 is a side view of the boiled noodle machine of FIG.
FIG. 3 is a partial cross-sectional view of the boiled noodle machine of FIG.
This boiled noodle machine 1 has a noodle basket that boiles 12 servings of spaghetti and automatically performs the following operations: (1) put the noodle in the noodle basket, (2) move the noodle basket in the hot water tank Boil the noodles while (3) pull the boiled noodles together with the noodle basket, (4) send the noodles from the raised noodle baskets to the noodle receiver basket.

The boiled noodle machine 1 has a rectangular box-shaped main body 3, and a hot water storage tank 10 for storing hot water is provided at the lower part of the main body. The height of the main body 3 is 1350 mm in this example, and is a height at which a person can look around from the upper side of the main body 3 even when installed near the center of the kitchen. The main body has a width of 1000 mm and a depth of 750 mm, which is a compact size.
In practice, the front surface of the hot water tank is closed by a front cover 5 (see FIGS. 2 and 3).

  The boiled noodle machine 1 includes a moving means 20 for moving a plurality (12 in this example) of spaghetti noodle baskets 40 in the hot water tank 10, a means for concentrating the boiling power from the heater on the noodle basket, Lifting device 60 for lifting the noodle basket from the hot water tank after being boiled, means for sending noodles from the noodle basket to the noodle receiver basket (noodle basket reversing mechanism) 80, exhaust means for exhausting exhaust gas including steam generated from the hot water tank, etc. Provided (details will be described later).

First, the structure of the hot water tank 10 will be described.
The hot water tank 10 has a substantially cylindrical shape, and a step 10b higher than the bottom is formed at the center of the bottom. A cylindrical boss 11 is erected on the stepped portion 10b. The inside of the boss 11 is hollow, and the height of the upper surface of the boss 11 is substantially equal to the height of the outer peripheral wall 10 a of the hot water tank 10. With such a structure, the portion where the noodles in the hot water tank 10 are boiled becomes an annular portion 13 between the outer peripheral wall 10 a of the hot water tank 10 and the outer periphery 11 a of the boss 11. The noodles are put in the noodle basket 40 and boiled while making a round of the annular portion 13 of the hot water tank by the noodle basket moving means 20.

  As shown in FIG. 3, in the annular portion 13 of the hot water tank, the clearance between the inner ring circle C1 of the rotation locus of the noodle basket 40-1 and the outer periphery 11a of the boss 11 can be made as small as possible. It is preferable that it is 3-6 mm. Further, the clearance between the outer ring circle C2 of the same locus and the outer peripheral wall 10a of the hot water storage tank 10 is as small as possible, and is preferably 3 to 6 mm as an example. Thus, the amount of hot water storage can be reduced to the minimum by reducing the capacity of the hot water storage tank 10 excluding the passage portion of the noodle basket 40 as much as possible. In this example, although the 260 mm long spaghetti dry noodle has the depth of the boiled noodle basket and the depth of the hot water tank, the capacity of the hot water tank 10 is about 55 liters (or 50 liters) Can also be).

As shown in FIGS. 1 and 2, a plurality (12 in this example) of heaters 15 are arranged at equal intervals on the bottom of the hot water tank annular portion 13. Each heater 15 is obtained by winding a rod-shaped heater in a circular shape approximately twice, and its upper surface is flat. Each heater 15 is directly attached to the bottom of the annular portion 13 and is directly exposed to hot water. Thereby, the heating power of the heater 15 can be directly transmitted to hot water. In one example, the power capacity of one heater 15 is 750 W, and since 12 heaters are used in this example, the total power is 9 kW. When the capacity of the hot water tank is 55 liters, the thermal efficiency divided by the amount of electric power used to input the amount of heat from the water temperature to boiling can be up to 97.4%.
If one of the heaters fails, only that heater needs to be replaced or repaired.

Next, the noodle basket moving means 20 will be described.
The noodle basket moving means 20 is a means for rotating the noodle basket 40 once in the annular portion 13 of the hot water tank. The means includes a noodle basket holder 21 that holds a plurality (12 pieces in this example) of noodle baskets 40 and a motor 29 that rotates the noodle basket holder 21 around the rotation shaft 23. As shown in FIG. 3, the noodle basket holder 21 includes a plurality of (in this example, twelve) arms 25 extending radially from the center of the hot water tank 10 to the annular portion 13, and a noodle basket provided at the tip of each arm 25. A noodle basket receiver 27 for receiving 40 is provided. The base end (center of the noodle basket holder) of each arm 25 is fixed to the tip of the rotating shaft 23. As shown in FIG. 1, the rotation shaft 23 extends downward from the center of the boss 11. A motor 29 is fixed to the lower end of the rotating shaft 23 via a reduction gear. When the rotating shaft 23 is driven by the motor 29 and rotates, the noodle basket holder 21 rotates around the rotating shaft 23.

The noodle basket holder 21 stops for a predetermined time (for example, 18 seconds) when the noodle basket reaches just above the heater 15. Then, the noodle basket holder rotation motor 29 is intermittently operated so that the noodle basket moves to the next heater 15 in a predetermined time (for example, 2 seconds). That is, the noodles put in the noodle basket are boiled while moving intermittently in the annular portion 13 of the hot water tank by the noodle basket moving means 20. Since the noodle basket stops right above the heater 15, the heat from the heater 15 can be concentrated on the noodle in the noodle basket, and the noodle can be well unwound by boiling flow.
Moreover, since each noodle basket 40 stays on the heater 15 for a fixed time, a uniform boiling force can be given to each noodle basket. For this reason, the noodles put in each noodle basket can be boiled to the same state.

  It should be noted that the noodle charging and discharging points (rotation start point) in the boiled noodle machine 10 are the positions of the noodle basket 40-1 (see FIG. 3) closest to the main body. That is, at this point, noodles are put into the noodle basket, go around the annular portion 13 of the hot water tank, return to the same point, and then the noodle basket 40 is pulled up by the lifting device 60 described later.

Next, means for concentrating boiling power from the heater on the noodle basket will be described.
First, the structure of the noodle basket will be described.
FIG. 4 is a diagram showing the structure of the noodle basket.
The noodle basket 40 has a cylindrical main body 41, a ring 43 is fixed to the mouth, and the bottom 41a is rounded. In one example, the main body has a diameter of 100 mm and a height of 246 mm. The diameter of 100 mm is close to the minimum necessary diameter for forming a boiling flow that flows radially from the center to the outer periphery in the noodle basket. Moreover, long noodles such as spaghetti can be handled by setting the height of the noodle basket to 246 mm. A disc-shaped rotation fulcrum 47 is provided on the side surface of the main body 41 so as to be hooked on a lifting device 60 described later. A tilt pin 49 is provided on the ring 43 on the side surface opposite to the rotation fulcrum 47.
The noodle basket 40 is received by the noodle basket receiver 27 of the noodle basket holder 21 by the ring 43.

  By making the bottom 41a of the main body into a round shape, there is no corner where the noodles are likely to be agglomerated. A boiling flow guide 45 is provided around the bottom. The boiling flow guide 45 has a downward truncated cone shape, and is, for example, a height of 34.5 mm and a diameter of the tip opening 45a of 74 mm. The boiling power of the hot water generated by the heater 15 is smoothly introduced into the noodle basket 40 from the guide tip opening 45a. Since there is such a boiling flow guide 45, the boiling flow containing a large amount of foam enters the noodle basket 40 without escaping to the side surface of the noodle basket 40 even though the bottom of the noodle basket 40 is hemispherical. It is like that.

As shown in FIG. 2, a boiling flow concentration plate 50 is disposed on the heater 15 of the hot water tank.
FIG. 5 is a perspective view showing the structure of the boiling flow concentration plate.
The boiling flow concentration plate 50 has an annular flat disc portion 50a, and an outer wall 50c and an inner wall 50b extending downward from the outer periphery and inner periphery of the disc portion. The width of the disc part 50 a is substantially equal to the width of the annular part 13 of the hot water tank 10. The lower surface of the disc portion 50a and the recess surrounded by the outer wall 50c and the inner wall 50b are divided into a plurality of (in this example, twelve) partitions 53 by a plurality of partition walls 51 extending in the radial direction of the concentrated plate 50. . The boiling flow concentration plate 50 is arranged so that the center of each heater 15 is located at the center of each section 53. In the center of each section 53 of the disc portion 50a, an opening (boiling flow concentration port) 55 is opened. An upward tapered guide 57 is provided above each opening 55.
With such a structure, each heater 15 causes boiling water in each section 53 to boil intensively and guides the boiling flow from the opening 55 to the guide 57 to flow intensively upward. Since the noodle basket 40 is located directly above the heater 15, the boiling flow is concentrated on the bottom of the noodle basket 40.

Next, the lifting device 60 that automatically pulls up the boiled noodle will be described.
FIG. 6 is an enlarged view of the lifting device.
The elevating device 60 is disposed in the boss 11 of the hot water tank, and pulls the noodle basket that has made a round in the hot water tank and returned to the rotation start point directly above the hot water tank. The device 60 includes a lifting rod 61 that can move up and down. The elevating rod 61 is guided by a guide (not shown) and is drawn upward from the upper surface of the boss 11 inside the rotation start point. An arm 63 is provided at the tip of the rod 61 so as to be hooked on the rotation fulcrum 47 of the noodle basket 40. When the lifting rod 61 is drawn upward from the upper surface of the boss 11, the rotation fulcrum 47 of the noodle basket 40 is caught by the arm 63, and the noodle basket 40 is pulled up from the hot water storage tank together with the arm 63 (two-dot chain line in FIG. 2). ).

  In the boss 11, a belt 65 with a rack is provided in parallel with the lifting rod 61. The belt 65 is wound endlessly between pulleys 67 that are spaced apart in the length direction of the lifting rod 61. The upper pulley 67 is fixed to the output shaft of an elevating motor (DC motor with a speed reducer) 69. When the lifting motor 69 is driven, the belt 65 rotates between the pulleys 67 along the guide 71.

  A slider 73 is fixed to the belt 65. The lifting rod 61 and the slider 73 are connected by a lever 75. When the elevating motor 69 is driven in one direction, the belt 65 rotates in the same direction, and the elevating rod 61 is raised via the lever 75. When the motor 69 is driven in the opposite direction, the elevating rod 61 descends. The rod 61 has a low position where the noodle basket is sufficiently immersed in the hot water tank (a position indicated by a solid line in FIG. 2), and a high position where the noodle basket is sufficiently lifted from the hot water tank (a position indicated by a two-dot chain line in FIG. 2). Go up and down between. The low position and the high position of the rod 61 are detected by limit switches 77 provided at two locations along the guide 71 of the belt 65 with a rack.

Next, the noodle basket reversing mechanism 80 for turning over the raised noodle basket and sending the noodles to the noodle receiver basket will be described.
As shown in FIG. 1, a noodle receiver basket 7 for receiving the boiled noodles is placed on the side of the hot water tank 10 of the main body 3. The reversing mechanism 80 rotates the noodle basket 40 pulled up straight by the elevating device 60 about 120 ° around the rotation fulcrum 47 (in the state indicated by the two-dot chain line in FIG. 1), from the mouth of the noodle basket 40. Send the noodles to the noodle receiver basket 7. The main body 3 of the boiled noodle machine is provided with a noodle sliding guide 9 extending from below the mouth of the noodle basket 40 to the noodle receiver basket 7 when the noodle basket 40 is inverted by 120 °.

FIG. 7 is a view showing a noodle basket reversing mechanism.
As shown in FIG. 2, the noodle basket reversing mechanism 80 includes a noodle basket rotating plate 81 that is rotatably fixed to the inner surface of the front cover 5. The rotating shaft 81 a of the noodle basket rotating plate 81 is coaxial with the rotation fulcrum 47 of the pulled noodle basket 40. The noodle basket rotating plate 81 is provided with a U-shaped pin tilting portion 83. When the noodle basket 40 is pulled up by the lifting device 60, the tilt pin 49 of the basket 40 engages with the pin tilting portion 83. The front cover 5 is provided with a pin guide 85 (see FIG. 2) that guides the tilt pin 49 straight up to the pin tilt portion 83 when the noodle basket 40 is pulled up by the lifting device 60. When the noodle basket rotating plate 81 rotates, the noodle basket 40 rotates about 120 ° around the rotation fulcrum 47 together with the pin 49 engaged with the pin tilting portion 83.

  The noodle basket rotating plate 81 is rotated by a motor (not shown) arranged on the side of the main body and capable of being driven in a reverse direction. A motor rotating plate 87 shown in FIG. 7 is fixed to the output shaft of the motor. The motor rotating plate 87 and the noodle basket rotating plate 81 are connected via two link arms 89. When the motor rotates in one direction (for example, clockwise), the noodle basket rotating plate 81 rotates counterclockwise via the motor rotating plate 87 and the link arm 89. As a result, the noodle basket 40 is inverted around the rotation fulcrum 47 to empty the noodle from the basket. Thereafter, when the motor rotates in the reverse direction (for example, counterclockwise), the noodle basket 40 rotates around the rotation fulcrum 47 to return the noodle basket 40 to an upright posture.

  As shown in FIG. 2, a substantially cylindrical noodle charging guide 91 is provided in the main body 3 above the noodle basket rotation start point. A pair of covers 93 that can be opened and closed are attached to the lower opening of the guide with spring-type hinges. The cover 93 is normally biased by a spring to close the lower opening. At this time, the tips of the covers are overlapped. When the noodles are put into the guide 91, the cover 93 is opened by the weight of the noodles, and the noodles fall from the guide 91. Below the guide 91 is a noodle basket 40 which is pulled up by the lifting device 60 and sent to the noodle receiver basket and then returned to the upright posture. The noodles fall into this noodle basket.

  A noodle container 95 is provided above the noodle charging guide 91. The noodle container is provided with a mechanism for quantifying the noodles and a mechanism for sending the quantified noodles to the noodle guide 91 (none is shown). After the noodles are sent to the noodle receiver basket 7 and the noodle basket returns to the upright posture, the quantified noodles are put into the noodle basket through the noodle guide 91.

Next, how noodles are boiled after being put into the noodle basket will be described.
When the noodle basket 40 is lowered by the elevating device 60 after the noodles are introduced into the noodle basket 40 from the noodle container 95 through the noodle introduction guide 91, the basket 40 is received by the noodle basket receiver 27 of the noodle basket holder 21. It is done. Then, the noodle basket holder 21 is driven by the moving means 20 to rotate. At this time, as described above, the noodle basket 40 stops on the heater 15 for a predetermined time (18 seconds), and then moves to the next heater for a predetermined time (2 seconds), and then goes around the annular portion 13 of the hot water tank 10. Then return to the noodle filling point. In this example, the noodles are boiled for 4 minutes. During this time, the boiling flow is concentrated on the noodles in the noodle basket 40 by the boiling flow concentration guide 45 (see FIG. 4) of the noodle basket 40 and the boiling flow concentration plate 50 of the hot water tank (see FIG. 5). Is boiled with stirring.

  When the noodle basket 40 returns to the rotation start point, the elevating device 60 lifts the noodle basket right above. Then, the noodle basket reversing mechanism 80 rotates the noodle basket 40 so that the boiled noodle passes through the noodle sliding guide 9 and is sent to the noodle receiving basket 7.

  In order to perform these operations in series, the noodle basket moving means 20, the elevating device 60, and the rotating mechanism 80 are controlled by the control unit 150 so as to operate in synchronization. In this example, the cycle of each apparatus is determined based on the operation cycle of the noodle basket moving means 20 (18-second stop, 2-second movement). For example, during the stationary cycle of the noodle basket moving means 20, the noodle basket is raised by the elevating device 60, the noodle basket 40 is rotated by the rotating mechanism 80, and the boiled noodle is sent to the noodle receiver basket 7. Thereafter, the noodle basket 40 is reversed by the mechanism 80 to return the noodle basket 40 to the upright posture, and the lifting device 60 lowers the noodle basket.

The boiled noodle machine of the present invention further includes exhaust means for exhausting exhaust gas containing steam generated from the hot water storage tank. The exhaust means includes a water-steam heat exchanger 100 (see FIGS. 1 and 2) for exchanging heat generated in the hot water storage tank with tap water.
An exhaust space 121 is provided above the hot water storage tank 10 of the main body 3. And the exhaust port 123 extended from the back side of the exhaust space 121 to the exhaust pipe 125 provided in the back of the upper surface of the main body is provided. An exhaust fan 111 is provided in the exhaust space 121. A hood 117 extending upward toward the exhaust space 121 is provided on the back wall of the main body 103.

The heat exchanger 100 is disposed in the exhaust space 121.
As shown in FIG. 2, the heat exchanger 100 includes a header 101, a footer 103, and a number of pipes 105 extending between the header 101 and the footer 103. The pipes 105 are arranged in two stages between the header 101 and the footer 103 in parallel. The heat exchanger 100 is disposed in the exhaust space 121 so that the header 101 is located on the front side and the footer 103 is located on the back side, and is inclined downward toward the front side. The front end of the hood 117 reaches almost the center of the heat exchanger 100.

  A tap water supply port 107 is provided at one end of the header 101, and a tap water discharge port 109 is provided at the opposite end of the footer 103. The tap water is supplied from the tap water supply port 107, flows in the header 101, flows in each pipe 105 to the footer 103 side, and is discharged from the tap water discharge port 109 of the footer 103. The tap water discharge port 109 is connected to a water supply pipe (not shown) to the hot water tank 10.

The steam generated from the hot water storage tank 10 rises right above the tip of the hood 117 and reaches the upper part of the exhaust space 121 through the pipes 105 of the heat exchanger 100 as indicated by the white arrows in FIG. Then, it again flows downward between the pipes 105, is guided by the exhaust port 121 and the hood 117, and is exhausted from the exhaust cylinder 125. When the water vapor passes between the pipes 105, heat is exchanged with the tap water in the pipes to lower the temperature and condensate. The condensed water adheres to the surface of the pipe 105 and falls directly into the hot water storage tank 10 as shown by the solid line arrow in FIG. Further, the water dropped on the upper surface of the hood 117 falls on the guide and is drained from the back side of the guide.
On the other hand, the tap water in the heat exchanger 100 is heated by exchanging heat with steam. The heated hot water is sent from the water supply pipe to the hot water tank 10 as hot water.

  The heat exchanger 100 can reduce the amount of steam discharged out of the boiled noodle machine and reduce white steam. For this reason, even when the boiled noodle machine 1 is installed in the center of the kitchen as described above, the field of view is not obstructed because there is little steam or white steam. Furthermore, it is possible to suppress the deterioration of the environment of the kitchen where the boiled noodle machine is installed, and the power consumption of air conditioning equipment such as air conditioners can be expected to decrease. In addition, since the capacity | capacitance of the hot water storage tank 10 is small as mentioned above, the quantity of the vapor | steam generated from a hot water storage tank itself also decreases.

Note that the heat exchanger 100 may be provided in a plurality of stages.
FIG. 8 is a diagram illustrating an arrangement state of the three-stage heat exchanger.
In this case, the heat exchangers 100-1, 2, and 3 are provided in three stages in the exhaust space 121. The innermost heat exchanger 100-1 is the first stage. Each heat exchanger 100 is arranged such that the header 101 is on the back side and the footer 103 is on the near side, and is inclined downward toward the near side.

  And tap water is supplied from the tap water supply port 107 of the header 101 of the first-stage heat exchanger 100-1. The tap water discharge port 109 of the footer 103 of the heat exchanger 100-1 is connected to the tap water supply port 107 of the header 101 of the second stage heat exchanger 100-2. Similarly, the tap water discharge port 109 of the footer 103 of the second stage heat exchanger 100-2 is connected to the tap water supply port 107 of the header 101 of the third stage heat exchanger 100-3. The tap water discharge port 109 of the footer 103 of the heat exchanger 100-3 is connected to a water supply pipe (not shown) to the hot water tank 10.

  Thus, the inside of all the heat exchangers 100-1, 2 and 3 communicates, and the tap water goes from the third-stage heat exchanger 100-3 to the first-stage heat exchanger 100-1. Flowing. On the other hand, the steam generated from the hot water tank 10 flows from the near side to the far side in the exhaust space 121. Thereby, the temperature of the tap water which comes out of the heat exchanger 100 can be raised. And the thermal energy of exhaust_gas | exhaustion is recoverable by pouring hot water into this hot water storage tank.

  As shown in FIG. 1, a hot water supply valve 131 for supplying hot water to the hot water storage tank 10 and a drain valve 133 for draining the hot water storage tank 10 are provided in a space below the hot water storage tank 10 in the main body 3. Further, a dew cover 135 is provided above the motor 29 of the noodle basket moving means 20 in the same space to prevent dew from falling on the motor. Further, a cooling fan 137 is provided to cool the inside of the boss 11 and the lower space.

Second embodiment

  In the above example, a boiled noodle machine (first example) for mainly boiling dry noodles (spaghetti) has been described. In the next example, a boiled noodle machine for raw noodles such as udon and ramen (second example) Will be described.

First, the overall structure of this boiled noodle machine will be described.
FIG. 9 is a front view showing the overall structure of a boiled noodle machine according to another embodiment of the present invention.
This boiled noodle machine 200 is box-like as a whole and has a noodle basket that boiles 10 meals of udon and ramen. The boiled noodle machine 200 has a boiled noodle portion 201 arranged on the right side of the figure. The noodle boiled portion 201 is a space whose periphery is covered with a cover or the like, and a hot water storage tank (symbol 230 in FIG. 10) or the like for boiling noodles is disposed inside. The front side of the noodle boiled portion 201 is closed with a cover 203 that can be opened and closed. Near the center of the cover 203, a noodle slot (noodle slot) 205 is opened for charging noodles into the hot water tank. The noodle slot 205 is provided with a guide 206 extending downward, and the noodle thrown from the slot 205 is thrown along the guide 206 into a predetermined noodle basket (reference numeral 250 in FIG. 10). The The noodle slot 205 is opened and closed by a manual opening / closing lid 207. An exhaust tube (exhaust hole) 215 is provided on the back side of the boiled noodle portion 201.
The boiled noodle machine 200 can be moved by a caster 217.

  On the side of the noodle boiled portion 201 (left side in the figure), a boiled noodle takeout portion 211 is provided. A noodle passage opening (noodle discharge hole) 209 for taking out the boiled noodles is opened in the side wall of the noodle boiled portion 201 on the noodle take-out portion 211 side. The noodle passage opening 209 is provided with a noodle guide 373 inclined downward. The noodles boiled in the noodle boiled portion 201 are put into a noodle receiving basket 213 placed in the noodle take-out portion 211 through the noodle passage opening 209.

  As described above, the portion where the inside of the noodle boiled portion 201 communicates with the outside is only the noodle charging port 205, the noodle passage port 209, and the like, and the inside of the noodle boiled portion 201 is a substantially sealed space. Therefore, it is possible to prevent the temperature inside the boiled noodle portion 201 from decreasing and to reduce the release of steam generated from the hot water storage tank into the kitchen chamber.

Next, the structure of each part of the boiled noodle machine will be described.
FIG. 10 is a front view showing the internal structure of the boiled noodle machine shown in FIG.
FIG. 11 is a side view showing the internal structure of the boiled noodle machine of FIG.
12 is a cross-sectional view showing the internal structure of the boiled noodle machine of FIG.
In the noodle boil unit 201 of the boiled noodle machine 200, a hot water storage tank 230, a mechanism (noodle basket moving mechanism) 280 for moving a plurality (ten in this example) of noodle baskets 250 in the hot water storage tank 230, boiled noodles Then, a mechanism (noodle discharge mechanism) 350 for lifting the noodle basket from the hot water storage tank 230 and sending the noodles to the noodle take-out section 211, and an exhaust device 420 for exhausting exhaust gas containing steam generated from the hot water storage tank 230 are provided. (Details will be described later). In addition, the noodle receiver 211 is provided with a draining mechanism 400.

First, the structure of the hot water tank 230 will be described.
As shown in FIG. 10, the hot water storage tank 230 is arranged at the middle stage in the noodle boiled portion 201 of the boiled noodle machine 200. The hot water storage tank 230 has a substantially cylindrical shape similar to the hot water storage tank of the boiled noodle machine in FIG. 1, and a cylindrical boss 231 is erected at the center of the bottom. The noodle basket 250 and the noodles put in the noodle basket 250 are boiled while the noodle basket moving mechanism 280 substantially goes around the annular portion 233 between the outer peripheral wall of the hot water tank 230 and the outer peripheral wall of the boss 231. A drain plate 234 is provided outside the annular portion 233 so as to project outward in a ring shape. As shown in FIG. 12, an edge 235 is erected on the boundary between the drain plate 234 and the annular portion 233 of the hot water tank 230.
In addition, as shown in FIG. 12, a drain outlet 236 is opened in a portion on the near side of the drain plate 234. A notch 237 in which the edge 235 is cut is formed at a position near the drain outlet 236 of the edge 235. When hot water overflows from the annular portion 233, the hot water flows from the notch 237 on the drain plate 234 and flows into the drain port 236.

  Note that raw noodles such as udon and ramen that are boiled by the boiled noodle machine 200 in this example are in a lump shape, and therefore, compared to the boiled noodle machine in FIG. The depth is shallow. As an example, the depth of the hot water tank 230 is 21 cm, the width of the annular portion 233 is 15 cm, and the capacity of the hot water tank 230 is about 44 liters.

  As shown in FIGS. 10 and 11, a plurality (ten in this example) of heaters 241 are arranged at equal intervals on the bottom of the annular portion 233. Each heater 241 is the same as the heater of the boiled noodle machine in FIG. 1 and is a rod-shaped heater wound approximately twice in a circular shape, and has a flat upper surface. A boiling flow concentrating plate 243 is disposed on the heater 241. The boiling flow concentrating plate 243 may have the same structure as the boiling flow concentrating plate of the boiled noodle machine shown in FIG. With the boiling flow concentration plate 243, the boiling flow can be concentrated on the bottom of the noodle basket 250.

Next, the structure of the noodle basket will be described.
13A and 13B are diagrams showing the structure of a noodle basket. FIG. 13A is a front view, FIG. 13B is a plan view, FIG. 13C is a right side view, and FIG. 13D is a left side view. FIG.
The noodle basket 250 includes a basket body 251 into which noodles are put, and a noodle discharge guide 261 extending upward from the basket body 251. The shape of the basket body 251 is a vertically long rectangular parallelepiped shape, and the upper surface 251a is open. The basket body 251 has an outer peripheral surface 251b positioned on the outer peripheral side of the hot water storage tank 230 in the annular portion 233 of the hot water storage tank 230, an inner peripheral surface 251c positioned on the inner peripheral side, both side surfaces 251d and 251e, and a bottom surface 251f.
The noodle discharge guide 261 extends upward from the upper edge of the outer peripheral surface 251b.

As can be seen from FIG. 13A, the opening upper surface 251a and the bottom surface 251f of the car body 251 are parallel. As can be seen from FIG. 13B, the shape of the opening upper surface 251a is a rectangle, and the shape of the bottom surface 251f is a trapezoid that tapers from the outer peripheral surface 251b toward the inner peripheral surface 251c. The area of the opening upper surface 251a is larger than the area of the bottom surface 251f.
Moreover, the outer peripheral surface 251b and the inner peripheral surface 251c of the basket body 251 are parallel as can be seen from FIG. As can be seen from FIG. 13C, the shape of the outer peripheral surface 251b is a trapezoid tapering downward. As can be seen from FIG. 13D, the shape of the inner peripheral surface 251c is a tapered trapezoid toward the bottom surface 251f. The area of the outer peripheral surface 251b is larger than the area of the inner peripheral surface 251c.
As can be seen from FIGS. 13C and 13D, the side surfaces 251d and 251e are closer to the center toward the bottom surface 251f and closer to the center toward the inner peripheral surface 251c.
With such a shape, the cross-sectional area of the car body 251 decreases as it goes from the opening upper surface 251a to the bottom surface 251f.

  Further, an inclined surface 251g extending obliquely from the inner peripheral surface to the bottom surface is formed between the inner peripheral surface 251c and the bottom surface 251f of the basket body 251. The action of the shape of each part of the inclined surface 251g and the car body 251 will be described later.

By making the cross-sectional shape of the cage body 251 polygonal, the cage body 251 has a shape that is closer to the shape obtained by dividing the annular hot water storage tank 230 into a fan shape. That is, as shown in FIG. 12, the fan shape includes an annular portion 233 having an outer peripheral wall of the hot water storage tank 230 as an outer peripheral circle and an outer peripheral wall of the boss 231 as an inner peripheral circle from the center of the hot water storage tank 230 and the boss 231. The shape is as close as possible to a fan-shaped shape defined by two sides extending in the radial direction at a central angle of 36 °. When the circumferential pitch of the hot water storage tank 230 and the boss 231 is the same, if the cross-sectional shape of the basket body 251 is a polygon, the cross-sectional area of the noodle basket can be made larger than when the cross-sectional shape of the basket body is circular. That is, the inner volume of the noodle basket can be increased. For this reason, the amount of noodles that can be processed can be increased without increasing the capacity of the hot water tank 230.
Alternatively, the height of the noodle basket 250 can be reduced by increasing the cross-sectional area. Also in this case, the amount of noodles that can be processed can be increased without increasing the capacity of the hot water tank 230. Conversely, the capacity of the hot water tank 230 can be reduced without reducing the amount of noodles that can be processed, and the thermal efficiency can be improved.
For example, the depth of the basket body 251 of the noodle basket 250 is 144.5 mm, the width (widest part) is 110 mm, and the depth is 121 mm.

  An upper frame 253 that is hooked by the noodle basket moving mechanism 280 is attached to the outer periphery of the opening upper surface 251a of the basket body 251 so as to project outward. A reinforcing lower frame 252 is attached along the periphery of the bottom surface 251f of the basket body 251. Note that each side of the car body 251 and the frames 253 and 252 are made of a stainless steel wire having a diameter of 3 mm in this example. Each surface of the basket body 251 has a stainless mesh of about 8 mesh.

  The noodle discharge guide 261 extends upward from the upper edge of the outer peripheral surface 251b of the basket body 251. The guide 261 has a guide body 263 through which noodles that have come out of the basket body 251 of the inverted noodle basket 250 and a bracket 265 for operating the noodle discharging mechanism 350 are provided. The guide body 263 has a U-shaped cross section, and has a guide plate extending upward from the upper edge of the outer peripheral surface 251b of the cage body 251 and side walls erected on the cage body side from both sides of the guide plate.

  The bracket 265 is provided substantially at the center in the height direction of the outer surface of the guide body 263 (opposite side of the noodle basket body). As shown in FIG. 13A, the bracket 265 has a curved surface 267 extending outward from the guide body 263. The curved surface 267 is convex downward, and a surface 267a curved upward from the lowest portion to the outside is a force point at which a noodle basket reversing actuator 350 (details will be described later) of the noodle payout mechanism operates. The tip 267b of the upper curved surface 267a is slightly curved outward. A through-hole 269 extending in parallel with the width direction of the car body 251 is opened inside the lowest portion of the curved surface 267 of the bracket 265. The noodle basket 250 is rotatably attached to the noodle basket moving mechanism 280 by connecting the through hole 269 and the noodle basket moving mechanism 280 with a pin (reference numeral 311 in FIG. 15). Here, the pin passed through the through-hole 269 becomes a rotation fulcrum when the noodle basket 250 is reversed. That is, as clearly shown in FIGS. 16 and 17, when the upper curved surface (power point) 267a of the bracket 265 is pushed downward by a horizontal bar 353 (details will be described later) of the reversing actuator 350, the noodle basket 250 rotates. It rotates outward (counterclockwise in FIG. 13A) around the fulcrum (through hole 269). Then, the noodles in the basket body 251 are paid out through the payout guide 261 (details will be described later).

Next, the noodle basket moving mechanism will be described.
As shown in FIGS. 10, 11, and 12, the noodle basket moving mechanism 280 rotates a noodle basket holder 281 that holds a plurality (ten in this example) of noodle baskets, and the noodle basket holder 281 around a rotation shaft 283. A motor 285 to be operated.

14A and 14B are diagrams for explaining the structure of the noodle basket holder. FIG. 14A is a plan view and FIG. 14B is a side view.
As shown in the figure, the noodle basket holder 281 includes a plurality of (in this example, 10) spoke-shaped arms 291 that radially extend from the rotation shaft 283 to the approximate center of the annular portion 233, and a noodle basket that branches at the tip of each arm 291. A holding frame 293 and an annular outer peripheral frame 295 connecting the tips of the noodle basket holding frames 293 are provided. As shown in FIG. 14B, each arm 291 extends outward from the rotating shaft 283 substantially horizontally, and then tilts downward until reaching the outer periphery of the boss 231 as shown in FIG. The hot water tank 230 extends horizontally up to substantially the center of the annular portion 233. A reinforcing ring 292 is attached to the corner between the horizontally extending portion and the downwardly inclined portion. The arm 291 has a rod shape with a circular cross section. The noodle basket holding frame 293 is manufactured by bending a stainless steel strip, and the outer peripheral frame 295 is also formed by circularly rounding the stainless steel strip.

  As shown in FIG. 14A, a pair of noodle basket holding frames 293-1 and 293-2 that are adjacent to each other with a space between adjacent spoke-like arms 291 are parallel to each other. A noodle basket holding portion 297 is formed between the pair of parallel noodle basket holding frames 293 and 293-2 and the outer peripheral frame 295 between the tips of these noodle basket holding frames. Since the noodle basket holding frame 293 and the outer peripheral frame 295 are made of a band-shaped member having a width as described above, the noodle basket 250 can be firmly held.

  A bracket receiver 301 that meshes with the bracket 265 of the noodle basket 250 is attached to the outside of each noodle basket holding portion 297 of the outer peripheral frame 295. Each bracket receiver 301 has an L-shaped support base 303 extending outward from the outer peripheral frame 295 and a noodle basket coupling base 305 erected from the base 303.

As shown in FIG. 14B, one piece of the support base 303 of each bracket receiver 301 extends outward from the outer peripheral frame 295, and the other piece extends downward. A rollable roller 309 is attached to the outside of the piece extending below.
The noodle basket coupling base 305 is erected from both sides of the outwardly extending piece of the support base 303 and is separated by the width of the bracket 265 of the noodle basket 250. A horizontal through hole 307 is formed near the upper end of the base 305.

Next, how the noodle basket 250 is attached to the noodle basket moving mechanism 280 will be described.
15 and 16 are views showing a state where the noodle basket is set on the noodle basket moving mechanism.
The noodle basket 250 is inserted from above the noodle basket holding portion (reference numeral 297 in FIG. 14A) of the noodle basket moving mechanism 280 so that the noodle discharging guide 261 is on the outside, and the noodle basket is placed at the upper frame 253 portion. It is set so as to be placed on the holding frame 293. Then, the bracket 265 of the noodle basket 250 is fitted between the noodle basket coupling bases 305 of the bracket receiver 301 of the outer peripheral frame 295. Next, the noodle basket 250 is attached to the outer frame 295 through the pin 311 through the through hole 269 of the bracket 265 and the through hole 307 of the noodle basket coupling base 305. When the noodle basket 250 is rotated outward (clockwise in FIG. 15) around the pin 311, the basket body 251 is inverted as shown in FIG. 16.

  The roller 309 contacts the drain plate 234 outside the hot water tank 230 and moves along the edge 235. The roller 309 receives the weight of the outer peripheral frame 295 and the noodle basket 250, reduces the driving resistance of the rotating mechanism 280, and smoothly drives the mechanism. When the rotation mechanism rotates, the roller 309 moves while rotating the drain plate 234 outside the hot water tank 230 along the edge 235.

  As shown in FIG. 14, the base end of each arm 291 (the center of the noodle basket holder 280) is fixed to the tip of the rotating shaft 283. The rotation shaft 283 extends downward from the center of the boss 231 as shown in FIG. A motor 285 is fixed to the lower end of the rotating shaft 283 via a reduction gear. When the rotating shaft 283 is driven by the motor 285 and rotates, the noodle basket holder 281 rotates around the rotating shaft 283.

  A disk 321 is attached to the base of the rotating shaft 283. By detecting the scale of the outer periphery of the disk 321 with the sensor 323, the rotation angle of the rotating shaft 283 can be detected. The motor 285 rotates such that when the noodle basket 250 reaches directly above the heater 241, it stops for a predetermined time (for example, 15 seconds), and then the noodle basket moves to the next heater for a predetermined time (for example, 5 seconds). Operate intermittently at an angle and speed.

  The noodle charging point (rotation fulcrum) in the boiled noodle machine 200 is a position A below the noodle charging port 205 (see FIG. 9) on the front side of the main body shown in FIG. Is a position B where the annular portion 233 is 9/10 times counterclockwise in the figure. A noodle passage 209 is provided on the side wall of the payout point B. The mouth 209 communicates with the noodle take-out unit 211. A guide 373 inclined downward from the noodle passage opening 209 toward the noodle receiver basket 213 disposed in the noodle take-out portion 211 is provided.

  The noodles are put into the noodle basket 250 at the rotation start point A, and the annular portion 233 of the hot water tank 230 is turned 9/10 in the counterclockwise direction in the drawing to reach the rotation end point B, and then pulled up by the noodle discharge mechanism described later. And is taken out through the noodle passage opening 209.

Next, the noodle dispensing mechanism will be described with reference to FIGS. 10, 11, 15, and 16. FIG.
The noodle payout mechanism includes a reversing actuator 350 that reverses the noodle basket 250. The reversing actuator 350 is attached to the main body side wall of the noodle basket 250 on the rotation end position side. The actuator 350 includes two parallel vertical bars 351. The vertical bars 351 are separated by an interval equal to or larger than the width of the noodle discharging guide 261 of the noodle basket 250. A horizontal bar 353 is spanned between the lower ends of the vertical bars 351. The upper end of each vertical bar 351 is fixed to the upper base 355. Each vertical bar 351 is guided by a guide 363 attached to the side wall.
On the other hand, a motor 357 for reversing the noodle basket is attached to the upper part of the side wall of the main body. The upper base 355 is connected to a rotary disk 359 fixed to the output shaft of the motor 357 via a link arm 361.

  When the rotating disk 359 is rotated in a certain direction by the motor 357, the upper base 355 moves downward via the link arm 361. As a result, each vertical bar 351 moves straight down along the guide 363. When the motor 357 is reversed and the rotary disk 359 rotates in the opposite direction, the upper base 355 moves upward via the link arm 361, and each vertical bar 351 moves straight along the guide 363. Thus, the vertical bar 351 and the horizontal bar 353 move in the vertical direction by the rotation in the direction opposite to the rotation of the motor 357.

The inversion operation of the noodle basket will be described with reference to FIGS.
FIG. 17 is a diagram schematically illustrating how the noodle basket is reversed.
FIG. 18 is a perspective view for explaining a state when the noodle basket is reversed.
When the noodle basket 250 reaches the rotation end point B by the noodle basket moving means 280, the reversing actuator 350 operates to lower the reversing vertical bar 351 and horizontal bar 353. Then, the horizontal bar 353 hits the upper part of the upper curved surface 267a of the bracket 265 of the noodle basket 250 as shown in FIGS. As shown in FIGS. 16 and 17B, when the horizontal bar 353 is further lowered, the upper curved surface 267a is pushed down while sliding with respect to the horizontal bar 353. Then, the noodle discharge guide 261 of the noodle basket 250 starts to rotate counterclockwise around the pin 311 so as to pass through between the vertical bars 351 outward. When the horizontal bar 353 is lowered to the final lowering position, as shown in FIGS. 17C and 18, the noodle basket 250 is rotated about 120 ° from the initial state, and the noodle discharging guide 261 is connected to the guide 373, and the basket body The noodles in 251 are discharged from the noodle discharge guide 261 through the guide 373 to the noodle receiver basket.

  Here, it is preferable that the moving speed of each bar by the reversing actuator 350 (the rotational speed of the motor 357) is variable. If the moving speed of each bar is increased and the basket is reversed at a high speed, the amount of broth to be dispensed with respect to the noodles to be dispensed increases. Depending on the type of noodles and dishes, the broth is useful for preventing the noodles from drying and improving the flavor.

  The noodle basket 250 is made of metal (for example, stainless steel). Further, since the noodle boiled noodles are contained in the basket body 251 when the noodle basket is inverted, the weight of the noodle basket 250 when the noodle basket is discharged is considerably heavy. Become. Therefore, in order to reverse the noodle basket 250 (pressing the inclined surface 267a of the noodle basket 250 downward), a strong force is required, and a strong load is applied to the rotary holder 281 of the noodle basket moving mechanism 280 when the noodle basket 250 is pressed down. Therefore, the noodle basket holding frame 293 and the outer peripheral frame 295 of the rotary holder 281 are made of a band-shaped member, and a roller 309 is provided on the outer peripheral frame 295 to provide load resistance.

  As described above, since the depth (121 mm) of the noodle basket 250 is slightly narrower than the width (150 mm) of the hot water tank 230, the noodle basket 250 is outward with the pin (rotation fulcrum) 311 as the center. When rotating, the inner peripheral surface 251 c of the basket body 251 hits the boss 231. Therefore, as shown in FIG. 10, a cutout portion 381 for allowing the noodle basket 250 to pass through is formed at a portion of the boss 231 corresponding to the payout point B of the noodle basket 250.

19A and 19B are diagrams for explaining the rotation trajectory of the noodle basket. FIG. 19A is a side view and FIG. 19B is a plan view.
Between the inner peripheral surface 251c and the bottom surface 251f of the basket body 251, the inclined surface (chamfered) 251g is provided as described above. By providing this inclined surface 251g, the diameter of the rotation locus of the noodle basket 250 around the pin (rotation fulcrum) 311 can be made as small as possible. As shown in FIG. 19A, when the noodle basket has no inclined surface, the side 251h ′ between the inner peripheral surface and the bottom surface of the noodle basket is separated from the pin (rotation fulcrum) 311 ( Draw a two-dot chain line in FIG. However, when the inclined surface 251g is provided, the locus of the noodle basket 250 moves backward by the dimension k in the drawing to the line indicated by the one-dot chain line in FIG. Thus, by providing the notch portion 251g in the noodle basket 250, the volume of the notch portion 381 of the boss 231 can be reduced as much as possible, and the volume of the hot water tank that is increased by providing the notch portion 381 can be reduced as much as possible. Can do.

Further, when the noodle basket 250 is reversed, the basket body passes between the adjacent arms 291. As shown in FIG. 19B, each arm 291 extends radially from the center of the hot water tank, so that the distance between adjacent arms 291 is narrower toward the center. When the noodle basket is reversed, the side 251h between the inclined surface and the bottom surface of the basket body 251 passes between the arms 291 while drawing a rotation locus farthest from the pin 311 (the locus is indicated by a two-dot chain line in the figure). . As shown in FIG. 13, the side 251 h is formed to be the narrowest among the sides of the car body 251, and thus can pass between the narrow arms 291. Thereafter, the side 251i between the bottom surface and the outer peripheral surface passes between the arms 291 (the locus is indicated by a one-dot chain line in the drawing). Since this side 251i is also made narrow, it can pass between the arms 291.
In this way, by making the surface of the car body 251 trapezoid narrower as it goes down, the shape of the car surface is made trapezoidal with a narrow inner peripheral surface (surface on the hot water tank center side) and a wide outer peripheral surface. The basket body 251 can pass between the adjacent arms 291.

Next, the draining mechanism 400 will be described with reference to FIG.
The draining mechanism 400 drains the noodles delivered to the noodle receiver basket 213. The noodle receiver basket 213 is placed on the concave receiver 403. A drain port 405 is opened at the bottom of the receiving part 403, and a drain pipe 407 extends from the drain port 405 to a watering chamber 409 disposed inside the main body. A pipe 411 is connected to the upper part of the water pulling chamber 409, and a decompression pump 413 is attached in the middle of the pipe 411.

  When the pump 413 is operated, the inside of the water drawing chamber 409 is depressurized, and thereby the air in the receiving portion 403 is drawn from the drain port 405 through the drain pipe 407. With this air flow, water is drawn down from the boiled noodles in the noodle receiver basket 213, and the noodles are drained.

Next, the steam exhaust apparatus 420 will be described.
FIG. 20 is a diagram for explaining the steam exhaust device.
Above the hot water storage tank of the main body, an exhaust space 423 defined by an upper wall, side walls, front and rear walls, and a pan 421 of the boiled noodle portion 201 is provided. A gap 425 is formed between the front end of the pan 421 and the front wall of the main body. Further, on the back side of the exhaust space 423, an exhaust port 427 extending to an exhaust cylinder 215 provided in the back of the upper surface of the main body is provided.

  In the boiled noodle device of this example, three-stage heat exchangers 431A, 431B, and 431C are provided in this order from the back side in the exhaust space 423. Each heat exchanger 431 is arranged in parallel so that the header 433 is disposed on the back side and the footer 435 is disposed on the near side, and a plurality of pipes 437 are inclined upward from the header 433 toward the footer 435.

  And the tap water supply port 439 is provided in the header 433A of the heat exchanger 431A on the innermost side (first stage), and tap water is supplied into the header 433A from the supply port 439. A tap water discharge port (not shown) is provided in the footer 435A of the heat exchanger 431A. The drain port is a feed pipe 441, and the header 433B of the center (second stage) heat exchanger 431B. It is connected to a tap water supply port (not shown). Similarly, the tap water discharge port of the footer 435B of the second stage heat exchanger 431B is connected to the tap water supply port of the header 433C of the frontmost (third stage) heat exchanger 431C via the feed pipe 443. ing. A tap water discharge port of a footer 435C of the heat exchanger 431C is connected to a water supply pipe (pipe pipe) 445 to the hot water storage tank.

  In addition, a front surface of the feed pipe 441 between the footer 435A of the first-stage heat exchanger 431A and the header 433A of the second-stage heat exchanger 431B is separated by a partition plate 447. Similarly, the front surface of the feed pipe 443 between the footer 435B of the second-stage heat exchanger 421B and the header 433A of the third-stage heat exchanger 431C is separated by a partition plate 449.

  In this way, all the heat exchangers 431 communicate with each other, and the tap water flows from the first stage heat exchanger 431A to the third stage heat exchanger 431C as indicated by the broken line arrows in the figure. Flowing. On the other hand, the steam generated from the hot water storage tank 230 enters the exhaust space 423 from the gap 425 formed on the front side of the exhaust space, as indicated by the solid line arrow in the figure, and first, the third stage heat exchanger 431C is passed through. pass. The second stage heat exchanger 431B's footer 435B and the third stage heat exchanger 431C's header 433C are separated by a partition plate 449, and the first stage heat exchanger 431A's footer 435A and the second stage heat exchanger 431C are separated from the second stage heat exchanger 431C. Since the partition 447 is also separated from the header 433B of the second heat exchanger 431B, the steam that has passed through the third heat exchanger 431C is above the footer 435B of the second heat exchanger 431B. And flows above the pan 421 that has passed through the second-stage heat exchanger 431B. Thereafter, the steam passes through the first-stage heat exchanger 431A and is exhausted from the exhaust port 427 through the exhaust pipe 215.

  A fan 451 is disposed on the side of the exhaust space 423. The room air sucked by the fan 451 is sent to the exhaust port 427. When the steam passes between the pipes of the heat exchangers, the heat is exchanged with tap water in the pipes to lower the temperature, and at the exhaust port 427, the steam is mixed with room air to lower the temperature. Thereby, the white vapor | steam exhausted from the exhaust pipe 215 can be reduced. Further, the water condensed by the heat exchanger adheres to the surface of the pipe, falls to the pan 421, and is drained through a water pipe (not shown).

  On the other hand, the tap water in each heat exchanger 431 is heated by exchanging heat with steam. The heated hot water is sent from the hot water pipe 445 to the hot water tank 230 as hot water. In addition, it is preferable that the hot water officer 445 extends to a position facing the drain outlet 235 (see FIG. 12) of the hot water tank 230 and is poured into the same position. This is the portion between the noodle charging position A and the fourth position in the rotation direction of the noodle basket moving means 280, which is the part where the boiling power is to be strongest in order to heat the noodles and loosen the noodles. It is because it is not preferable to do. Moreover, by pouring hot water at a position opposite to the drainage port 235, hot water can easily flow uniformly toward the drainage port 235 in the hot water storage tank 230, and dirt such as nudge on the surface of the noodles in the hot water storage tank is easily discharged. Become.

  Such boiled noodle devices are usually washed once a day. When cleaning hot water tank 230, noodle basket holder 281 is removed from rotating shaft 283, and noodle basket 250, noodle basket holder 281 and hot water tank 230 are cleaned. Moreover, when the pan 421 is removed, the heat exchanger or the like can be washed with water from below.
