  However, the above-described conventional stove burner has a structure in which a central passage for supplying a secondary air is opened at the center for mounting a temperature detection device, and boiling occurs during cooking. There is a problem that the boiled broth may enter the central passage and contaminate the inside, or may hang on the temperature detection device to fix the holder.

  The present invention has been made in response to the above-mentioned problems of the prior art, and may cause boiling liquid to enter the central passage and contaminate the inside, or may be hung on a temperature detection device to fix the holder. Aims to provide a no-burner stove burner.

In order to solve the problems described above, the stove burner of the present invention adopts the following configuration. That is,
The bottom surface side is formed in an annular shape, and a burner head having a plurality of flame ports opened on the outer peripheral side surface, and an annular shape having an open upper surface is formed, and the burner head is placed thereon. A burner body forming a mixed gas chamber of a shape; and a mixing passage connected to the burner body for mixing fuel gas and air and supplying the mixed gas chamber to the mixed gas chamber; At the stove burner,
A vertically movable metal moving member provided in a central passage passing through the center of the burner head;
A temperature detection unit that detects the temperature of the moving member;
A supporting member for supporting the moving member so as to be movable in the vertical direction;
A biasing member for biasing the moving member upward;
A disc-shaped umbrella portion having an outer diameter larger than the inner diameter of the central passage of the burner head and equal to or less than the outer diameter of the burner head is formed at the upper end of the moving member.
The upper surface of the umbrella portion is in a state of being protruded from the upper surface of the Vitoku by urging the moving member upward by the urging member.
The temperature detection unit detects a temperature on the back surface side of the umbrella portion.

  In the stove burner of the present invention, a moving member having a disc-shaped umbrella formed at the upper end is provided in the central passage of the burner head. The moving member is supported by the supporting member in a vertically movable manner in the central passage, and can detect the temperature on the back side of the umbrella portion. The outer diameter of the umbrella portion is set to be equal to or smaller than the outer diameter of the burner head, but larger than the inner diameter of the central passage of the burner head. Therefore, even if boiling occurs during cooking, the boiling juice is not blocked by the umbrella portion and does not enter the central passage. As a result, there is no possibility that the inside of the stove burner may be contaminated with boiling water or the moving member may be fixed to the support member by the boiling water. In addition, when the mixed gas is burned by a plurality of flame ports, the air rises in the central passage formed at the center of the burner head, and the flame as secondary air from the gap between the upper surface of the burner head and the umbrella portion The flames formed at the plurality of flame ports can be maintained to continue the combustion of the mixed gas.

  Further, in the stove burner of the present invention described above, the portion of the upper surface of the burner head which is at least the outer side of the outer diameter of the umbrella portion may be inclined toward the outer side.

  In this way, even if the boiled broth gets on the umbrella part, it can be discharged outward, so that it can be prevented from flowing into the central passage.

  Moreover, in the stove burner of this invention mentioned above, you may form the upper surface of an umbrella part in spherical shape convex upwards.

  In this way, even if boiling juice is applied to the umbrella portion, the boiling juice can be discharged to the outside, so that it is possible to make it difficult for the remaining juice to remain on the upper surface of the umbrella portion. As a result, it is possible to prevent the situation in which the boiled soup adhering to the upper surface of the umbrella portion is deposited and the heat from the cooking container is not easily transmitted or the appearance of the stove burner is impaired.

  Moreover, in the stove burner of this invention mentioned above, it is good also as detecting the temperature of the back surface side of an umbrella part as detecting a temperature non-contactingly.

  If the temperature on the back side of the umbrella portion is detected, even if the temperature is detected without contact, the cooking is stable and accurate over a long period of time without being affected by dirt and the like attached to the bottom of the cooking container. It is possible to detect the temperature of the container.

  Further, as described above, in the stove burner of the present invention for detecting the temperature on the back side of the umbrella portion in a noncontact manner, the temperature detection portion is attached to the support member while covered with a sensor window of a material transparent to infrared rays. You may do so.

  By so doing, even if the sensor window is soiled for some reason and the temperature detection accuracy is lowered, it is possible to easily recover the detection accuracy by wiping the sensor window.

FIG. It is explanatory drawing about the stove burner 10 of the modification which attached the temperature sensor 21 to the back surface side of the burner cap 13. FIG.

  FIG. 1A is a perspective view showing the external shape of a stove burner 10 of the present embodiment mounted on a gas stove 1. As illustrated, the stove burner 10 of the present embodiment is provided at an opening 2 a that opens to the top plate 2 of the gas stove 1. The upper part of the burner body 11 mentioned later protrudes from the opening part 2a, and the burner head 12 mentioned later is mounted on the burner body 11. As shown in FIG. The burner head 12 has a substantially annular shape, and in the portion to be mounted on the burner body 11, a plurality of flame hole grooves forming a plurality of flame ports 12a with the burner body 11 are bored. ing. Further, above the burner head 12, a burner cap 13 formed of a metal material having high thermal conductivity such as aluminum is mounted. Furthermore, in the periphery of the stove burner 10, Vitoku 3 on which a cooking vessel such as a pot is placed is mounted.

  FIG. 1B is a perspective view showing the burner cap 13 removed. As illustrated, the burner cap 13 includes a cylindrical shaft portion 13 b and a substantially disc-shaped umbrella portion 13 a formed on the upper end of the shaft portion 13 b. The upper surface of the umbrella portion 13a has a spherical shape slightly convex upward, and an upper inclined surface 13c inclined outward is formed on the entire outer periphery of the umbrella portion 13a. Further, the burner head 12 has a substantially annular shape with a central passage 12c formed at the center, and the lower side is inclined toward the outside over the entire circumference of the upper surface of the burner head 12 as well. The surface 12 b is formed. Furthermore, a substantially cylindrical support pipe 14 described later is provided at the center of the central passage 12c of the burner head 12, and the burner cap 13 inserts the upper portion of the support pipe 14 into the shaft portion 13b of the burner cap 13. Thus, it is mounted in a vertically movable state. The burner cap 13 of the present embodiment corresponds to the "moving member" of the present invention, and the support pipe 14 of the present embodiment corresponds to the "support member" of the present invention.

  FIG. 2 is a longitudinal sectional view showing the structure of the stove burner 10 of the present embodiment. As illustrated, the stove burner 10 of the present embodiment includes a burner body 11, a burner head 12 mounted on the burner body 11, and a burner cap 13. The burner body 11 accommodates an inner plate 11i made of sheet metal press-formed into a cylindrical shape having a smaller diameter than the outer plate 11o in an outer plate 11o made of sheet metal press-formed into a large diameter cylindrical shape, A mixed gas chamber 16 is formed in the space between the outer plate 11o and the inner plate 11i.

  Further, the outer side plate 11o has a passage upper portion 11a formed by being press-formed into a wedge shape in which a part of the end is extended and the part is opened downward. Similarly, the passage lower side 11b is formed by pressing the inner plate 11i in a wedge shape in which a part of the end is extended and the part is opened upward. Then, when the upper passage portion 11a formed at the end of the outer plate 11o and the lower passage portion 11b formed at the end of the inner plate 11i are assembled facing each other, the outer plate 11o is formed in a cylindrical shape. The cylindrical portion of the inner plate 11i is accommodated in the inside of the hook portion. The mixing passage 17 is formed between the passage upper side 11a and the passage lower side 11b by assembling the opposing passage upper side 11a and the passage lower side 11b in an airtight state.

  Further, one end side of the mixing passage 17 is an open end 17 o opening in a circular shape, and the gas injection nozzle 20 is provided to face the open end 17 o. When fuel gas is injected from the gas injection nozzle 20 toward the open end 17 o as shown by a broken arrow in the figure, the fuel gas flows into the mixing passage 17 from the open end 17 o while entraining surrounding air. Then, while flowing toward the mixed gas chamber 16 in the mixing passage 17, the mixed gas is mixed with air to be mixed gas and flows into the mixed gas chamber 16. As described above, since the burner head 12 forming the upper side of the mixed gas chamber 16 has a plurality of flame ports 12a, the mixed gas flowing into the mixed gas chamber 16 flows out from the flame port 12a to the outside. . The mixed gas can be ignited if the spark is blown from a spark plug (not shown) to the mixed gas flowing out from the flame port 12a to the outside.

  The burner head 12 is a substantially annular member formed by forging or die casting of aluminum alloy, brass or the like (see FIG. 1 (b)), and has a shape in which a central passage 12c having a circular cross section penetrates at the center ing. Further, the upper end of the cylindrically formed portion of the outer plate 11o is bent inward to form an annular mounting surface 11f. Then, by placing the burner head 12 on the mounting surface 11 f, a plurality of flame ports 12 a are formed between the burner head 12 and the burner body 11.

  A hollow support pipe 14 having a substantially cylindrical shape is provided at the center of a central passage 12c of the burner head 12, and the lower end side of the support pipe 14 is screwed to a bracket 18 made of a sheet metal. The bracket 18 is fastened together with the burner body 11 to a not-shown burner bracket that supports the burner body 11 from the lower surface side. As a result, as shown in FIG. 1 (b), the support pipe 14 is erected at the center of the central passage 12 c of the burner head 12.

  The shaft portion 13 b of the burner cap 13 is formed in a hollow cylindrical shape having an inner diameter larger than the outer diameter of the support pipe 14, and a coil spring 15 is inserted inside the shaft portion 13 b. Then, when the burner cap 13 is placed on the support pipe 14 in a state where the upper portion of the support pipe 14 is inserted inside the shaft portion 13 b, the burner cap 13 is supported by the support pipe 14 in a vertically movable state. It will be Moreover, in this state, the upper surface of the burner cap 13 is in a state of projecting more than the upper surface of the Vitoku 3 (that is, the surface on which the cooking container is placed). The coil spring 15 of the present embodiment corresponds to the "biasing member" in the present invention.

  FIG. 3 is an enlarged cross-sectional view showing a portion encircled by a broken line in FIG. 2 in an enlarged manner. As shown, a recess 19 a is formed at the upper end of the support pipe 14 provided at the center of the central passage 12 c of the burner head 12. A temperature sensor 19 is attached to the inside of the recess 19a to detect the temperature of the object in a noncontact manner by detecting infrared rays, and the temperature sensor 19 is covered by a sensor window 19w attached to the recess 19a. It is The sensor window 19 w is formed of a heat-resistant material that transmits infrared light. Also, the wiring 19L connected to the temperature sensor 19 is drawn to the outside through the inside of the support pipe 14. The temperature sensor 19 of this embodiment corresponds to the "temperature detection unit" in the present invention.

  As described above, the shaft portion 13 b of the burner cap 13 is hollow, and the coil spring 15 is accommodated inside the shaft portion 13 b. The coil spring 15 is fitted and attached to the outer periphery of a convex portion 13d which is provided in a disk shape and protrudes from the umbrella portion 13a at the upper end inside the shaft portion 13b. When the burner cap 13 is attached to the support pipe 14 by inserting the support pipe 14 inside the shaft portion 13 b, the burner cap 13 is biased upward by the coil spring 15 and supported.

  Further, the outer diameter d of the umbrella portion 13a formed at the upper end of the shaft portion 13b is larger than the inner diameter D3 of the central passage 12c of the burner head 12 but smaller than the outer diameter D1 of the burner head 12 There is. Furthermore, as described above with reference to FIG. 1 (b), a lower inclined surface 12 b that inclines outward is formed on the entire outer periphery of the upper surface of the burner head 12. The inner diameter D2 is set to be smaller than the outer diameter d of the umbrella portion 13a of the burner cap 13.

  FIG. 4 is an explanatory view exemplifying a state in which the cooking container is placed on the vantage 3 in the stove burner 10 of the present embodiment. As described above with reference to FIG. 3, the burner cap 13 is urged upward by the coil spring 15. Further, as described above with reference to FIG. It protrudes more than the upper surface. For this reason, when the cooking container is placed on Gotoku 3, the burner cap 13 is pushed down at the bottom of the cooking container, and the bottom of the cooking container and the burner cap 13 come into contact with each other reliably. Then, as described above with reference to FIG. 1A, since the burner cap 13 is formed of a metal material having high thermal conductivity, when the bottom of the cooking vessel is heated by the stove burner 10, the bottom of the cooking vessel is Heat is quickly transferred to the burner cap 13 so that the burner cap 13 is at the same temperature as the bottom of the cooking vessel. Further, as described above with reference to FIG. 3, since the temperature sensor 19 for detecting the temperature of the object without contact is attached to the upper end of the support pipe 14, the burner by the cooking vessel placed on Vitoku 3 When the cap 13 is pushed down, the end face of the convex portion 13 d protruding from the back surface side of the burner cap 13 approaches the temperature sensor 19. Therefore, the temperature sensor 19 can detect the temperature of the end face of the convex portion 13d of the burner cap 13, and as a result, the temperature of the cooking container can be detected.

  Further, on the upper surface of the burner cap 13, an upper inclined surface 13c is formed at the outer edge portion, and further, a lower inclined surface 12b is formed at the outer edge portion of the upper surface of the burner head 12. For this reason, even if boiling occurs during heating of the cooking vessel and the boiling broth is transmitted to the outside of the cooking vessel and flows to the burner cap 13, the boiling broth is from the upper inclined surface 13c of the burner cap 13 It is transmitted to the lower side 12b of the head 12 and flows to the outside of the stove burner 10. Arrows shown by thick broken lines in FIG. 4 indicate that the boiled broth transmitted from the outside of the cooking vessel flows to the outside of the stove burner 10. As described above, even if the boiled broth flows to the burner cap 13, it does not flow into the central passage 12 c of the burner head 12, so the inside of the stove burner 10 may be contaminated or the burner cap 13 and the support pipe 14 may be separated. There is no sticking of boiled broth between the two.

  In addition, as shown in FIG. 1A, the central passage 12c of the burner head 12 is covered with the umbrella portion 13a of the burner cap 13. Therefore, for example, when moving the cooking vessel on Gotoku 3, even if the soup is accidentally spilled, the soup goes into the central passage 12 c to contaminate the inside of the stove burner 10 or the burner cap 13 It does not stick to the support pipe 14.

  Furthermore, although the burner cap 13 is smaller than the outer diameter of the burner head 12, the burner cap 13 covers the burner head 12. Therefore, the user can see the upper surface of the burner cap 13 but does not see a complicated structure such as the central passage 12c and the support pipe 14 provided at the center of the central passage 12c. It can also give the user an impression. In addition, since the upper surface of the burner cap 13 is formed in a spherical shape convex upward, for example, when moving the cooking container from Gotoku 3, the soup etc. hangs on the burner cap 13 for some reason However, since the simmered liquid tends to flow from the burner cap 13, it is possible to suppress a situation in which the upper surface of the burner cap 13 is contaminated with simmered water or the like.

  Moreover, in the stove burner 10 of the present embodiment, as described above, the method of transmitting the heat of the cooking vessel to the burner cap 13 and detecting the back side of the burner cap 13 by the non-contact temperature sensor 19 is employed. . By this, even when the gas stove 1 is used for a long time, the temperature of the cooking vessel can be detected stably and accurately. Below, this point is explained in detail.

  If a non-contact temperature sensor 19 is used, it is possible to directly measure the temperature at the bottom of the cooking vessel without the intervention of the burner cap 13. Therefore, as in the stove burner 90 illustrated in FIG. 5, a through hole 93 h for temperature detection is formed at the center of the burner cap 93 provided above the burner head 12 (see FIG. 5 (a)). It is considered normal to attach a temperature sensor 19 to the upper part of the support pipe 14 below the hole 93 h (see FIG. 5 (b)). In this way, when the cooking vessel is placed on Vitoku 3, the temperature sensor 19 can detect the temperature at the bottom of the cooking vessel through the through hole 93 h of the burner cap 93. Moreover, since this method directly detects the temperature at the bottom of the cooking vessel without the intervention of the burner cap 13, it is an excellent method capable of detecting the temperature quickly and accurately. It was initially thought that there was no.

  However, when the temperature of the cooking vessel was actually detected, it was found that the variation in temperature became larger than when detected using a conventional non-contact temperature sensor. And when the reason is examined in more detail, it has been found that if rust or dirt adheres to the bottom of the cooking vessel, the variation becomes large. On the other hand, in the conventional temperature sensor, the temperature did not greatly vary depending on the degree of rust and dirt adhering to the bottom of the cooking vessel. The reason is considered to be as follows. First, the non-contact temperature sensor 19 utilizes a phenomenon called “thermal radiation” in which the surface of an object emits electromagnetic waves (mainly infrared rays) with an intensity corresponding to temperature, and detects the intensity of infrared rays, The temperature is detected by converting the detected intensity into a temperature. Here, even if the surface temperature of the object is the same, the intensity of the emitted infrared radiation varies depending on the material of the object. For this reason, the intensity of the radiated electromagnetic wave changes in the case where it adheres to the bottom of the cooking container and the case where it does not adhere, and as a result, the temperature detected by the temperature sensor 19 also changes. it is conceivable that. In contrast, conventional temperature sensors detect temperature using heat transfer (not heat radiation), and heat transfer is ultimately obtained although the rate of heat transfer varies depending on the material. The temperature never changes. For this reason, it is considered that the correct temperature could be detected regardless of the presence of dirt or the like fixed to the bottom of the cooking container.

  Therefore, although the stove burner 10 of the present embodiment uses the non-contact temperature sensor 19, it does not directly detect the temperature of the bottom of the cooking vessel, but dares to heat the cooking vessel to the burner cap 13 After the transmission, the temperature on the back side of the burner cap 13 is detected. In this way, the heat of the cooking vessel is transferred to the burner cap 13 by heat transfer, so the temperature of the bottom of the cooking vessel can be properly conducted to the burner cap 13 regardless of the presence or absence of dirt or the like adhering to the bottom of the cooking vessel. . And, as shown in FIG. 4, since the back surface side of the burner cap 13 (in particular, the end surface of the convex portion 13d) has a structure that is not easily soiled, the temperature can be always detected under the same conditions. For this reason, even when the gas stove 1 is used for a long time, it is possible to detect the temperature of the cooking container stably and accurately.

  In addition, the temperature sensor 19 is covered by a sensor window 19 w formed of a material that transmits infrared light. For this reason, even if the sensor window 19w gets soiled for some reason, as shown in FIG. 1B, the sensor window 19w can be easily cleaned by removing the burner cap 13. As a result, it is possible to detect the temperature of the cooking container with high accuracy over a long period of time.

  As mentioned above, although the stove burner 10 of a present Example was demonstrated, this invention is not limited to said Example, It is possible to implement in a various aspect in the range which does not deviate from the summary.

  For example, in the embodiment described above, the temperature on the back side of the burner cap 13 is detected using the non-contact temperature sensor 19. However, as illustrated in FIG. 6, the contact-type temperature sensor 21 may be attached by filling the heat-resistant ceramic filler 23 in the recess 22 on the back side of the burner cap 13. Even in this case, the temperature of the cooking vessel can be detected by detecting the temperature of the burner cap 13. Also in this case, the central passage 12c and the support pipe 14 are covered by the burner cap 13 and can not be seen by the user, as in the above-described embodiment, so that the impression is refreshing, and in addition, the simmerant etc. There is no risk of entering into the passage 12c to contaminate the interior of the stove burner 10 or sticking the burner cap 13 to the support pipe 14.

  In the stove burner 10 of the modification shown in FIG. 6, the temperature sensor 21 is inserted by inserting the temperature sensor 21 into the recess 22 on the back side of the burner cap 13 and filling it with the heat resistant ceramic filler 23. It is attached. For this reason, depending on the state in which the temperature sensor 21 is inserted in the recess 22 or the state in which the ceramic filler 23 is filled, the characteristic of detecting the temperature by the temperature sensor 21 may vary. On the other hand, when the non-contact temperature sensor 19 is used as in the above-described embodiment, it is possible to obtain the advantage that the characteristic of detecting the temperature hardly varies.
