Description

[0001] Temperature Detecting Apparatus [0002]

The present invention relates to a temperature detecting device for detecting the temperature of a cooking container placed on a container base of a stove.

In recent years, in order to prevent accidents such as frying oil fire due to overheating, a gas stove is generally provided with a temperature detecting device for detecting the temperature of a cooking container such as a pot placed on a container base. The temperature detecting device includes a support pipe installed at the central opening of the annular stove burner, a cylindrical holder mounted on the upper portion of the support pipe so as to be movable in the vertical direction, and a holder A coil spring for biasing the coil spring, a heat collecting member attached to the upper end of the holder, and a temperature sensor attached to the lower surface of the heat collecting member.

In such a temperature detecting device, the upper portion of the holder is provided so as to protrude upward from the center of the container support. When the cooking vessel is placed on the vessel base, the holder is pushed down by the bottom of the vessel and the collecting member is pressed against the bottom of the vessel by the biasing force of the coil spring. As a result, it becomes possible to detect the temperature of the cooking container to be delivered to the heat collecting member by the temperature sensor.

Further, in order to mount the holder so that the support pipe can move up and down, the following structure is widely applied (for example, Patent Document 1). At the upper end of the support pipe inserted into the holder, a washer having a smaller diameter than the holder is provided. On the other hand, on the lower side of the holder, there is formed a small diameter portion whose diameter is smaller than that of the left holder. When the holder is moved upward, the small diameter portion engages with the left holder to prevent it from slipping out. It guides the movement. The slope of the holder is regulated so that the heat collecting member abuts on the bottom of the cooking container in an appropriate posture by reducing the gap between the inner periphery of the thinned portion and the outer periphery of the support pipe.

JP 2008-170038 A

However, in the temperature detecting apparatus having the above-described structure, when the oil that is scattered during cooking or the broth that has boiled over from the cooking vessel adheres to the support pipe, the oil or the boiling broth is highly viscous There is a problem that the small diameter portion is fixed to the support pipe, and the holder may not move.

The present invention has been made in response to the above-described problems of the prior art, and it is an object of the present invention to provide a temperature detecting device capable of suppressing sticking of a holder by oil or boiling broth attached to a support pipe.

In order to solve the above-described problems, the following configuration is applied to the temperature detecting device of the present invention. In other words,

A temperature detecting device for detecting the temperature of a cooking container placed on an inner side of an annular stove burner and placed on a container base,

A support pipe disposed inside the stove burner,

A holder in which an upper portion of the support pipe is inserted and which is movable in a vertical direction,

A heat collecting member attached to an upper end of the holder,

A temperature sensor mounted on a lower surface of the heat collecting member,

A coil spring for urging the holder upward;

The guide pipe is inserted into the lower end side of the holder and the support pipe is inserted into the annular inner side and is guided along the support pipe to guide the movement of the holder in the vertical direction and,

And a plurality of protruding portions that are in line contact with the other in a vertical direction are formed in either the inner periphery of the guide member or the outer periphery of the support pipe.

In the temperature detecting device according to the present invention, the inner circumference of the guide member and the outer circumference of the support pipe are in line contact with the plurality of protrusions, so that the adhesion area due to the oil attached to the support pipe or the boiling broth is wider And it is difficult for the guide member to be fixed to the support pipe, so that it is possible to prevent the holder from moving.

It is also possible to suppress the tilting of the holder by reducing the clearance between the plurality of projections formed on the inner periphery of the guide member and the outer periphery of the support pipe or by reducing the clearance between the plurality of projections formed on the outer periphery of the support pipe and the inner periphery of the guide member. It is possible to improve the detection accuracy of the temperature of the cooking container by the temperature sensor by bringing the heat collecting member into contact with the bottom of the cooking container in an appropriate posture.

In the above-described temperature detecting device of the present invention, the number of protrusions may be four or more, and the protrusions may be arranged at regular intervals in the circumferential direction of the support pipe.

In this case, since the two protrusions are formed in pairs, and are in line contact with the outer periphery of the support pipe or the inner periphery of the guide member at the opposite position through the support pipe, the effect of suppressing the holder tilting can be enhanced.

Further, in the temperature detecting device of the present invention, the following may be employed. At first, the upper end of the support pipe is provided with a large plate having a larger diameter than the inner diameter of the guide member. Then, when the holder moves upward, the guide member abuts against the left leg, thereby preventing the support pipe from deviating. The upper surface of the guide member is inclined with respect to the lower surface of the left arm.

This reduces the contact area between the guide member and the left-hand metal, as compared with the case where the upper surface of the guide member and the lower surface of the left-hand metal are parallel. As a result, even when the oil or the boiled broth enters between the guide member and the left bank, the upper surface of the guide member is hardly fixed to the lower surface of the left arm, so that the holder can be prevented from moving.

In the temperature detecting device of the present invention, the outer circumference of the guide member may be provided with an abutment portion abutting against the inner circumference of the holder and an abutment portion abutting against the inner circumference of the holder.

In this way, even if oil or boiling broth enters the holder, it is discharged from the clearance between the matching portion and the inner periphery of the holder. As a result, since the guide member is hardly fixed to the left leg by oil or boiling broth, it is possible to restrain the holder from moving.

In the temperature detecting apparatus of the present invention described above, the upper surface of the guide member may be inclined downward from the inside toward the opposed contact portion.

By doing so, the oil or the boiling broth that has entered between the guide member and the left metal can be guided outwardly according to the inclination of the guide member, and can be discharged from the clearance between the matching portion and the inner periphery of the holder. As a result, the oil or the boiling broth hardly sticks to the inside of the guide member, so that the guide member can be prevented from sticking to the support pipe.

Provided is a temperature detecting device capable of suppressing sticking of a holder by oil or boiling broth attached to a support pipe.

The guide member formed in a ring shape is fitted to the lower end side of the cylindrical holder and a support pipe is inserted inside the guide member. The guide member slides along the support pipe to guide the movement of the holder in the up and down direction. A plurality of protruding portions which are in line contact with the other in the vertical direction are formed on either the inner periphery of the guide member or the outer periphery of the support pipe. As a result, the inner periphery of the guide member and the outer periphery of the support pipe come into line contact with the plurality of projections, whereby the adhesion area due to the oil adhered to the support pipe or the boiled broth is drastically reduced as compared with the case of surface contact, Since the guide member is hardly fixed, it is possible to prevent the holder from moving.

6 is an explanatory view showing the shape of the support pipe 115 in the temperature detecting device 100 according to the modification.

1 is a sectional view showing the structure of a gas furnace 1 equipped with the temperature detecting device 100 of the present embodiment. The gas furnace 1 is provided with a top plate 2 covered with an upper surface of a furnace body not shown and a furnace burner 10 provided in the furnace body by protruding an upper portion from a through hole 3 formed in the top plate 2 And a container holder 4 provided on the top surface of the top plate 2 for placing a cooking container such as a pot above the furnace burner 10.

The stove burner 10 includes a burner body 11 in which a toric mixing chamber 11a is formed, a mixing tube 12 extending from the burner body 11 in communication with the mixing chamber 11a, An annular burner head 13 mounted on the burner body 11 so as to cover the upper opening of the chamber 11a and a toric burner cover 14 mounted above the burner head 13, have.

When the fuel gas is injected toward the upstream opening 12a of the mixing pipe 12 extending from the burner body 11, the primary air for combustion is swept into the mixing pipe 12. Then, the fuel gas passing through the mixing tube 12 and the primary air are mixed, and the mixed gas is supplied to the mixing chamber 11a.

A plurality of grooves are formed radially with respect to the center of the burner head 13 on the lower surface of the outer peripheral wall of the burner head 13 A plurality of flutes 13a communicating with the mixing chamber 11a are formed by the plurality of flute grooves and the upper surface of the burner body 11. [ The mixed gas supplied to the mixing chamber 11a is ejected from the plurality of balls 13a, and when the flame is scattered by the spark plug not shown in the drawing, the combustion of the mixed gas is started. In the center of the burner head 13, a secondary air supply passage 13h necessary for combustion of the mixed gas is formed. The burner cover 14 has a role of restraining the boiling soup from being buried in the burner head 13 when boiling over from the cooking container placed on the container base 4. [

In the supply passage 13h of the burner head 13, a temperature detecting device 100 is provided. The structure of the temperature detecting device 100 will be described later with reference to a separate drawing. The upper portion of the temperature detecting device 100 protrudes upward from the center opening 14a of the burner cover 14. [ When the cooking container is placed on the container base 4, the top of the temperature detecting device 100 abuts against the bottom of the cooking container, and the temperature of the cooking container is detected.

Fig. 2 is an explanatory view showing an internal structure by taking a section of the temperature detecting device 100. Fig. The temperature detecting apparatus 100 includes a support pipe 115 installed in the supply passage 13h of the burner head 13, a substantially cylindrical holder 110 mounted on the support pipe 115, A heat collecting member 111 mounted on the upper end of the holder 110 and a temperature sensor 112 mounted on the lower surface of the heat collecting member 111.

The upper end of the holder 110 formed by the sheet metal is bent inward in the radial direction to form a top face 110a and an inner side of the top face 110a is bent downward to form a cylindrical inner peripheral portion 110b are formed. A cylindrical peripheral wall portion 111a having a diameter smaller than that of the inner peripheral portion 110b protrudes downward from a lower surface of the substantially disk-shaped collecting member 111 having a smaller diameter than the holder 110, The peripheral wall portion 111a is press fitted into the inner peripheral portion 110b so that the heat collecting member 111 is attached to the upper end of the holder 110. [

The temperature sensor 112 is housed inside the peripheral wall portion 111a, and is fixed with a filler or the like. The temperature sensor 112 of the present embodiment uses a thermistor whose electrical resistance is changed by a change in temperature. The temperature sensor 112 can detect the temperature transmitted to the lower surface of the heat collecting member 111. Two lead wires 113 are drawn from the temperature sensor 112 and connected to a control unit not shown in the drawing.

At the upper end of the support pipe 115, an annular left arm 116 having a diameter smaller than that of the holder 110 is joined by caulking, not shown. This holder 116 is inserted into the holder 110 from below. An annular guide member 120 is press-fitted into the holder 110 in a state in which the support pipe 115 is inserted into the insertion hole at the center in the lower part of the left arm 116. The guide member 120 is slid along the support pipe 115 so that the holder 110 can be moved in the axial direction of the support pipe 115 (Upward and downward directions in the figure). The guide member 120 also functions as a stopper for preventing the support pipe 115 from being pulled out by abutting against the left arm 116 when the holder 110 moves upward.

A coil spring 117 is accommodated in the holder 110 in a compressed state between the top surface 110a and the left arm 116. The coil spring 117 is inserted into the holder 110 I am compelled upward. The cable 114 covered with the two lead wires 113 extending from the temperature sensor 112 is inserted into the inside of the coil spring 117 and the inside of the support pipe 115.

In this temperature detecting device 100, when the cooking container is placed on the container base 4, the holder 110 is pressed down by the bottom portion of the cooking container, and heat is generated by the biasing force of the coil spring 117 The member 111 is pressed against the bottom of the cooking utensil. Therefore, the temperature of the cooking container can be detected by the temperature sensor 112 through the heat collecting member 111. [ The holder 110 is pushed up by the urging force of the coil spring 117 and the guide member 120 is held at a position where it abuts the left arm 116. [

3 is a perspective view showing the guide member 120 of the present embodiment. As shown in the figure, the guide member 120 is formed in an annular shape having a through hole 120h through which a support pipe 115 is inserted in the center. A plurality of protrusions 120p projecting radially inward are formed on the peripheral surface of the insertion hole 120h. In the example shown in the figure, four protrusions 120p are formed in the circumferential direction of the insertion hole 120h As shown in FIG.

The outer periphery of the guide member 120 is formed in a rectangular shape having a round shape different from the inner periphery of the substantially cylindrical holder 110. When the holder 110 is press- Four corner portions 120c abutting against the inner circumference of the frame member 120 and four edge portions 120s not abutting against each other. When the guide member 120 is cut at the position A-A in Fig. 3, the cross section shown in Fig. 2 is obtained. The edge portion 120c of the present embodiment corresponds to the "abutting portion" of the present invention, and the edge portion 120s of the present embodiment corresponds to the "abutment portion" of the present invention.

As described above, in the holder 110, the guide member 120 slides along the support pipe 115 so that the upward and downward movement is guided. However, the support pipe 115 may be splashed with oil or boiled broth from the cooking vessel during cooking. In the temperature detecting apparatus 100 of the present embodiment, the holder 110 is prevented from moving due to oil or boiling broth, which is suppressed by applying the guide member 120 having the shape shown in Fig. Hereinafter, this point will be described. First, as a preparation, the temperature detection device 100 of the conventional example in which oil or boiling broth is attached to the support pipe 115 may cause the holder 110 to be unable to move .

4 is an explanatory view showing a conventional temperature detecting device 100 in which the holder 110 is prevented from moving due to oil or boiling broth attached to the support pipe 115. [ Fig. 4 (a) is a cross-sectional view of a lower portion of the holder 110 of the conventional example cut along a plane passing through the center of the support pipe 115. Fig. A neck portion 110c having a diameter smaller than that of the left arm 116 is formed at the lower end of the holder 110 shown in the figure. When the holder 110 moves upward, the neck portion 110c So that the support pipe 115 is not pulled out by being engaged with the left bank 116. Further, the thinned portion 110c slides along the support pipe 115 to guide the upward and downward movement of the holder 110. [

The gap between the thinned portion 110c and the support pipe 115 is made small so that the inclination of the holder 110 is restricted so that the heat collecting member 111 abuts on the bottom of the cooking vessel in an appropriate posture, It is preferable to make the inner diameter of the baffle plate small. On the other hand, when the clearance between the thinned portion 110c and the support pipe 115 is reduced, the oil attached to the support pipe 115 and the boiling broth flow into the clearance, so that the thinned portion 110c ) Is likely to stick.

4 (b) shows a state in which the thinned portion 110c is fixed to the support pipe 115 in a cross-sectional view cut in a plane perpendicular to the support pipe 115. In Fig. As shown in the drawing, the inner periphery of the thinned portion 110c and the outer periphery of the support pipe 115 are both circular in cross-sectional shape and are in surface contact with each other. As a result, the oil that has flowed into the gap or the boiled broth becomes a viscous adhesive due to a change over time, so that the thinned portion 110c is fixed to the support pipe 115. As the clearance between the thinned portion 110c and the support pipe 115 is reduced, the area of adhesion due to oil or boiled broth tends to increase, and is more firmly fixed. As a result, even if the cooking container is placed on the container base 4, even if the holder 110 is not lowered and the cooking container becomes unstable or the cooking container is removed from the container base 4, It is impossible to detect the temperature of the cooking container.

5 is an explanatory view showing the reason why it is possible to prevent the holder 110 from being moved even if oil or boiling broth is attached to the support pipe 115 in the temperature detecting device 100 of the present embodiment . 5 (a) is a cross-sectional view in which the position where the guide member 120 of the holder 110 of the present embodiment is press-fitted is cut into a plane perpendicular to the support pipe 115. As shown in the drawing, the insertion hole 120h of the guide member 120 is formed with four projections 120p, which are not circular in sectional shape but protrude inward in the radial direction from the inner peripheral surface. Thereby, the support pipe 115 inserted into the insertion hole 120h comes into line-contact with the projecting portion 120p in the vertical direction. As a result, the adhesion area due to the oil attached to the support pipe 115 or the boiled broth is drastically reduced as compared with the case of surface contact, and it becomes difficult for the guide member 120 to be fixed to the support pipe 115, It is possible to prevent the holder 110 from being moved.

Since the tilting of the holder 110 can be suppressed by reducing the clearance between the plurality of protrusions 120p and the support pipe 115, it is possible to prevent the heat collecting member 111 from contacting with the bottom of the cooking container in a proper posture Thus, the detection accuracy of the temperature of the cooking container by the temperature sensor 112 can be improved. Particularly, in the guide member 120 of the present embodiment, the four projections 120p are arranged at regular intervals in the circumferential direction of the support pipe 115, and the projections 120p are paired two by two, Side contact with the support pipe 115, the effect of suppressing the tilting of the holder 110 can be enhanced.

Further, the edge portion 120c and the edge portion 120s are formed on the outer periphery of the guide member 120 of the present embodiment. When the guide member 120 is press-fitted into the holder 110, the edge portion 120c abuts against the inner periphery of the holder 110 while the edge portion 120s abuts against the holder 110, . Owing to this, even when oil or boiling broth flows into the holder 110, oil or boiled broth are discharged from the gap between the edge portion 120s and the holder 110. [ As a result, since the guide member 120 is hardly fixed to the left arm 116 by oil or boiling broth, it is possible to prevent the holder 110 from moving.

5 (b) is a cross-sectional view of the lower portion of the holder 110 taken along the line B-B in Fig. 5 (a). As shown in the drawing, the upper surface of the guide member 120 is inclined with respect to the lower surface of the left arm 116. The contact area between the guide member 120 and the left arm 116 becomes smaller than when the upper surface of the guide member 120 and the lower surface of the left arm 116 are parallel to each other. As a result, even when oil or boiling broth flows between the guide member 120 and the left arm 116, the upper surface of the guide member 120 is hardly fixed to the lower surface of the left arm 116, It is possible to inhibit the movable member 110 from moving.

Particularly, the upper surface of the guide member 120 of this embodiment has a downward slope from the inner insertion hole 120h toward the outer edge portion 120s. The oil or the boiling broth flowing between the guide member 120 and the left arm 116 is guided outward along the inclination of the guide member 120 so that the gap between the edge portion 120s and the holder 110 As shown in Fig. As a result, the oil or the boiling broth hardly sticks to the inside (the insertion hole 120h) of the guide member 120, so that the guide member 120 can be prevented from being fixed to the support pipe 115.

In the temperature detecting device 100 of the present embodiment described above, there are the following modifications. Hereinafter, a modification will be described focusing on the points different from the above embodiment.

6 is an explanatory view showing the shape of the support pipe 115 in the temperature detecting device 100 according to the modification. In the temperature detecting apparatus 100 of the above-described embodiment, a plurality of protruding portions 120p are formed on the inner circumferential surface of the guide member 120, and are in line contact with the support pipe 115. On the other hand, in the temperature detecting device 100 of the modified example, as shown in a perspective view in Fig. 6 (a), the upper end of the support pipe 115 (downward of the left pad 116) protrudes outwardly in the radial direction A plurality of projections 115p are formed. In the example shown in the figure, four projections 115p are arranged at equal intervals in the circumferential direction of the support pipe 115, and the length of the projections 115p in the vertical direction is shorter than the vertical distance of the holder 110 It is long.

6 (b) is a cross-sectional view in which the guide member 120 and the support pipe 115 of the modified example are cut in a plane perpendicular to the support pipe 115. As shown in the figure, in the guide member 120 of the modified example, when the sectional shape of the insertion hole 120h is substantially circular and the support pipe 115 of FIG. 6A is inserted, the protrusion 115p is inserted into the insertion hole 120h in the vertical direction. In the temperature detection device 100 of this modified example, as in the above-described embodiment, the adhesion area due to the oil attached to the support pipe 115 or the boiling soup is smaller than in the case of surface contact, It is difficult for the guide member 120 to be fixed to the holder 115, thereby preventing the holder 110 from moving. Since the tilting of the holder 110 can be suppressed by reducing the clearance between the plurality of protrusions 115p and the inner peripheral surface of the insertion hole 120h, the temperature detection accuracy of the cooking container by the temperature sensor 112 can be improved Can be improved.

As described above, the temperature detecting device 100 of the present embodiment and the modified example has been described. However, the present invention is not limited to the above-described embodiments and modifications, and various modifications can be made without departing from the gist of the present invention Do.

For example, in the above-described embodiment, the four protrusions 120p are formed in the guide member 120, but the number of the protrusions 120p is not limited to four but may be three or more. The number of protrusions 120p is preferably an even number (four, six, eight) than the odd number. The effect of suppressing the tilting of the holder 110 can be enhanced by making the two projections 120p in pairs and bringing the two pairs of projections 120p into line contact with the support pipe 115 at the opposite position with the support pipe 115 interposed therebetween.
