Description

Gas Range {GAS RANGE}

The present invention relates to a gas range having a temperature sensor which is installed in a through-hole in the center of the burner part and contacts the bottom of the cooking vessel to detect the temperature of the cooking vessel.

As a gas range of this kind, an umbrella-shaped cover is attached to the upper part of the temperature sensor, and when the temperature sensor is pressed down by the cooking vessel, the cover is also lowered to cover the through hole of the burner part (Patent Document 1). In addition, there is a structure in which a conical bearing cover is attached to the side surface of the temperature sensor so that the cover covers the through hole of the soup tray located below the burner (Patent Document 2). In the gas range, even if the soup boiled from the cooking vessel flows down the temperature sensor when the burner is used, the boiled soup is infiltrated into the body of the range from the burner's through hole or through the soup tray's through hole by the cover attached to the temperature sensor. It is preventing.

However, in each of the above-mentioned gas ranges, when the burner in which the cooking vessel is not placed on the burner portion is not used, the through-holes of the burner portion are opened without being blocked by the cover (the gas range of Patent Literature 2 also penetrates through the center of the burner portion). Since the hole is referred to as the vent hole "13," the cover does not block the through hole of the burner even when the temperature sensor is moved upward. Therefore, when the burner is not in use, dust, oil splashed from adjacent range parts, water or detergents when cleaning the top plate, etc., infiltrate into the range body through the burner through-holes and contaminate the inside of the gas range. There was a problem such as.

DISCLOSURE OF THE INVENTION In view of the above circumstances, an object of the present invention is to provide a gas range capable of preventing intrusion of various by-products into a through hole of a burner portion against an unused gas burner.

Gas range according to the present invention,

In the gas range provided with a temperature sensor which is installed standing with a gap between the through-hole formed in the center of the burner portion, the temperature sensor for detecting the temperature of the cooking vessel by touching the bottom of the cooking vessel,

In the upper part of the burner through-hole, a small diameter step part having a small inner diameter is formed,

The side part of the temperature sensor is provided with a sunshade projecting outward over the entire circumference,

The shading portion is separated from the small diameter step portion of the through hole in a state where the temperature sensor is pressed down by the cooking vessel, and touches the small diameter step portion of the through hole in a state where the temperature sensor does not touch the cooking vessel and is moved upward. It is made of a configuration to close the gap between the through-hole and the temperature sensor.

By the above configuration, when the burner in which the cooking vessel is not placed on the burner is not used, the upper part of the through hole of the burner is blocked by the shade formed in the temperature sensor. Therefore, when the burner is not in use, it is possible to prevent dust, oil splashed from the adjacent range portion, water splashes such as detergent or the like when cleaning the top plate, and the like, into the through hole of the burner portion. In addition, in the state where there is no cooking vessel on the burner, the shade of the temperature sensor closes the through-hole of the burner, so that the inside of the range main body cannot be seen from the through-hole of the burner, thereby improving the appearance of the gas range.

When using the burner on which the cooking vessel is placed on the burner, the shade formed in the temperature sensor is spaced apart from the small-diameter step of the through-hole of the burner to form a gap between the burner's through-hole and the temperature sensor. As a result, air is introduced into the through hole of the burner from the lower side, and the air flows outward from the gap to be supplied as combustion air to the flame forming portion of the burner, thereby ensuring a good combustion state of the gas burner. In addition, since the air flowing out of the gap prevents the air around the temperature sensor from being overheated by the heat generated from the gas burner, it is possible to prevent the temperature sensor from incorrectly detecting the temperature of the cooking vessel.

In the gas range,

The temperature sensor has an outer insulation cover to block heat from the gas burner,

The heat insulation cover is formed in a tubular shape consisting of a large diameter tube portion having a lower portion and a large diameter portion having a lower portion, and having a small diameter portion having an upper portion.

It is preferable that the said shading part is comprised by the step part formed between the large diameter cylinder part and the small diameter cylinder part of a heat insulation cover.

As a result, the shading portion is integrally formed by a heat insulating cover which is a component of the temperature sensor. Thus, when the burner is not in use, the temperature sensor is moved upward and the gap between the through-hole of the burner portion and the temperature sensor is closed. We can be surely blocked by wealth.

In the gas range,

It is preferable that the small-diameter stepped portion of the shade portion and burner portion of the temperature sensor is formed in a tapered shape in contact with each other.

As a result, when the burner in which the cooking vessel is not placed on the burner is not in use, the tapered portion of the shade portion of the temperature sensor and the tapered portion of the small-diameter step of the burner portion are brought into contact with each other, so that the burner through-hole and the temperature sensor A gap can be reliably closed by the said shading part. In addition, when the burner is not in use, the tapered portion of the sunshade portion of the temperature sensor and the tapered portion of the small-diameter step portion of the burner contact each other, whereby the temperature sensor is placed upright and perpendicular to the center of the through hole. Therefore, when the burner is used, the temperature sensor does not incline with respect to the bottom of the cooking vessel when the cooking vessel is placed, and contacts vertically, so that the temperature of the cooking vessel can be accurately detected by the temperature sensor.

As mentioned above, according to the gas range which concerns on this invention, when the burner in which the cooking container is not put on the burner part is not used, since the upper part of the through-hole of the burner part is blocked by the shading part formed in the temperature sensor, it is not used. Various fly products can be prevented from invading the gas burner into the through hole of the burner. Therefore, when the burner is not in use, no fly matter enters the range body and contaminates the inside of the gas range, thereby ensuring a clean state.

1 and 2 illustrate a gas range with a pan bottom temperature sensor, and in the gas range 1 of the present invention, a burner opening 13a is formed in an upper plate 13 covering an upper surface of the range body 12. The gas burner 2 disposed in the range main body 12 faces the burner opening 13a. The trivet 11 is arrange | positioned on the upper plate 13 so that the gas burner 2 may be enclosed. The gas burner 2 is provided with a pan bottom temperature sensor 5 (temperature sensor). In addition, the gas range 1 heats the cooking vessel A placed on the trivet 11 by the flame of the gas burner 2, and the pan bottom temperature sensor 5 sets the cooking vessel A. The temperature of the cooking vessel A is detected by abutting the bottom of the pan.

The gas burner 2 includes a mixing tube 22 for mixing fuel gas and primary air, an annular burner body 23 connected to the mixing tube 22, and a burner part disposed on the burner body 23 ( 21). The burner body 23 has an inner cylinder portion 23a and an outer cylinder portion 23b and is fitted into the insertion hole 14a of the burner ring 14 attached to the burner opening 13a of the upper plate 13. The burner portion 21 has a cylindrical burner head 31 attached to the outer cylinder portion 23b of the burner body 23 and a burner cap 32 detachably disposed on the burner head 31. . The burner cap 32 is formed in a disk shape, and a through hole 33 is formed at the center thereof, and a pan bottom temperature sensor 5 is disposed in the through hole 33. The burner head 31 has a plurality of flame holes 31a formed thereon, and blows out the mixer supplied from the mixing pipe 22 and the burner body 23 to the burner head 31 from the flame holes 31a. Burn. Moreover, the flame hole 31a may be formed in the burner cap 32 side. In addition, an ignition electrode and a flame detector (not shown) are arranged around the burner head 31.

The pan bottom temperature sensor 5 is inserted into the through hole 33 in the center of the burner cap 32, and is installed standing up with a gap between the through holes 33. The pan bottom temperature sensor 5 detects the temperature by contacting the bottom of the cooking vessel A placed on the trivet 11 with the upper end disposed higher than the upper surface of the trivet 11. The pot bottom temperature sensor 5 is comprised from the support pipe 81 installed upright in the inner space of the inner cylinder part 23a of the burner body 23, and the thermal head 7 formed in the upper end of the support pipe 81. As shown in FIG. The support pipe 81 is fixed to the support plate for the gas burner 2 which is not shown by the fixing member. The heat-sensitive head 7 surrounds the heat collecting plate 71 which abuts on the bottom of the cooking container A, the protective cylinder 72 whose upper end is closed by the heat collecting plate 71, and the protective cylinder 72 so as to surround the gas burner 2. It is provided with a heat insulating cover 73 to block the heat. The heat sensitive head 7 is provided with a heat sensitive element 71a such as a thermistor which detects the temperature of the cooking vessel A via the heat collecting plate 71 on the lower surface of the heat collecting plate 71. The lead wire 82 (refer FIG. 1) is extended from the thermosensitive element 71a, this lead wire 82 passes out through the support pipe 81, and is taken out outside, and the detection temperature of the pot bottom temperature sensor 5 is extended. Is connected to a controller (not shown) which controls the gas burner 2 according to the above. Moreover, the protective cylinder 72 is slidably fitted in the outer side of the spring support 75 attached to the upper end of the support pipe 81. And the spring 74 is provided between the said spring support 75 and the heat collecting plate 71, and the thermal head 7 is supported by the spring 74 upwards with respect to the support pipe 81, and is supported. . As a result, when the cooking vessel A is placed on the trivet 11, the thermal head 7 is pressed down against the holding force of the spring 74, and the heat collecting plate 71 compresses the spring 74. By the reaction force, the bottom portion of the cooking vessel A is reliably contacted (see FIG. 4).

In the gas range 1 of the present invention, when the burner in which the cooking container A is not placed on the burner part 21 is not used, various by-products pass through the through hole 33 of the burner cap 32. Do not break into me. As the structure, the through-hole 33 of the burner cap 32 is formed by the inner periphery of the cylindrical part 34 extended downward from the lower surface of the burner cap 32 in the burner part 21. As shown in FIG. The through hole 33 is a small diameter portion 35 having the smallest diameter formed in the upper opening portion, and a tapered small diameter formed so as to increase in diameter from the small diameter portion 35 toward the lower side. (Iii) A stepped portion 37 and a large diameter portion 36 having the largest diameter formed under the small diameter stepped portion 37.

3, in the pan bottom temperature sensor 5, the side surface part is provided with the shading part 51 which protruded outward over the whole circumference. Specifically, the heat insulation cover 73 of the pot bottom temperature sensor 5 is formed in the tubular shape which consists of the large diameter cylinder part 73a with a thick bottom, and the narrow diameter cylinder part 73b with a thin top. The large diameter tube portion 73a is formed with an outer diameter smaller than the inner diameter of the large diameter portion 36 of the through hole 33 and larger than the inner diameter of the small diameter portion 35, and the small diameter tube portion 73b is formed of the small diameter of the through hole 33. The outer diameter smaller than the inner diameter of the neck portion 35 is formed. The sunshade 51 is formed by a tapered stepped portion 73c formed between the large diameter cylindrical portion 73a and the small diameter cylindrical portion 73b of the heat insulating cover 73 so as to have a smaller diameter toward the upper side.

And the shade part 51 formed integrally with the heat insulation cover 73 which is a component of the pot bottom temperature sensor 5, the pot bottom temperature sensor 5 does not contact a cooking container A, and is burnt upwards. By being moved, the gap between the through hole 33 and the pot bottom temperature sensor 5 is closed by contacting the small diameter step portion 37 of the through hole 33 of the burner cap 32 (see FIG. 2). ). As a result, the upper portion of the through hole 33 of the burner cap 32 is closed when the burner in which the cooking container A is not placed on the burner portion 21 is closed, so that it is scattered from dust or an adjacent range portion. It is possible to prevent the infiltration of the oil, the upper plate 13, and the like into the through-holes 33 by splashes such as water or detergent. At this time, the through-hole 33 and the pot bottom temperature sensor are brought into contact by the tapered portion of the sunshade 51 of the pot bottom temperature sensor 5 and the tapered portion of the small-diameter step portion 37 of the through-hole 33 contacting each other. Since the gap between (5) can be reliably closed, it can reliably prevent the invasion of the infiltration into the through hole 33. In addition, when the burner is not used, the pot bottom temperature sensor 5 contacts the tapered portion of the sunshade 51 and the tapered portion of the small diameter step portion 37 of the through hole 33 by contacting the burner. It is installed vertically upright to fit the center of (33). Therefore, when using the burner, when the cooking vessel A is placed, the pot bottom temperature sensor 5 abuts against the bottom of the cooking vessel A vertically, so that the pot bottom temperature sensor ( The temperature detection of the cooking container A by 5) can be performed correctly. Moreover, in the state in which there is no cooking container A on the burner part 21, the shade part 51 of the pot bottom temperature sensor 5 closes the through-hole 33 of the burner cap 32, and the burner Since the inside of the range main body 12 cannot be seen from the through hole 33 of the cap 32, the appearance of the gas range 1 is improved.

On the other hand, referring to Figure 4, when using the burner on which the cooking vessel A is placed on the burner unit 21, the pot bottom temperature sensor 5 is pushed down by the cooking vessel A and the pot bottom temperature sensor 5 The gap between the through hole 33 and the pot bottom temperature sensor 5 is separated by the shade 51 from the small hole step portion 37 of the through hole 33 of the burner cap 32. Is formed. As a result, air flows into the through hole 33 from the lower side of the burner portion 21 by the upward flow, and the air flows outward from the gap between the small diameter portion 35 and the pot bottom temperature sensor 5. Since combustion air is supplied to the flame hole 31a of the burner part 21, the favorable combustion state of the gas burner 2 is ensured. In addition, since the air flowing out of the gap prevents the air around the pot bottom temperature sensor 5 from being heated by the heat generated from the gas burner 2, the pot bottom temperature sensor 5 is a cooking vessel ( The misdetection of the temperature of A) can be prevented. In addition, since the heat insulation cover 73 is made of a large diameter tube portion 73a having a lower side while the lower surface is opened, heat generated from the gas burner 2 at the time of use of the burner can be easily radiated from the large diameter portion 73a. The bottom temperature sensor 5 can be prevented from erroneously detecting the temperature of the cooking container A.

As described above, in the gas range 1 equipped with the pot bottom temperature sensor of the present invention, the pot bottom temperature sensor 5 is not used when the cooking vessel A is not placed on the burner portion 21. By moving upward, the through hole 33 of the burner cap 32 is blocked by the shade 51 of the pot bottom temperature sensor 5 (see Fig. 2), and the cooking vessel A is the burner portion. At the time of use of the burner placed on (21), the through hole 33 of the burner cap 32 is opened by pressing down the pan bottom temperature sensor 5 (see Fig. 4). Therefore, since various scattering products can be prevented from infiltrating into the through hole 33 with respect to the unused gas burner 2, the scattering products penetrate into the range body 12 and contaminate the inside of the gas range. It can be kept clean. In addition, when the burner is used, air flows through the through hole 33 of the burner cap 32, and air flowing out from the gap between the pan bottom temperature sensor 5 and the through hole 33 sparks in the burner part 21. Since the hole 31a is supplied as combustion air, a good combustion state of the gas burner 2 is ensured.

In addition, in the said embodiment, although the shading part 51 of the pot bottom temperature sensor 5 is comprised by the step part 73c which protruded from the heat insulation cover 73, for example, as shown in FIG. The sunshade part 51 may be comprised by the umbrella-shaped flange member 6 detachably attached to the side part of the cover 73. In this case, the position of the flange member 6 can be adjusted suitably, and the through-hole 33 of the burner cap 32 is matched with the small diameter step part 37 in accordance with the rising position of the pan bottom temperature sensor 5. The contact state can be easily adjusted.

Moreover, as shown in FIG. 6, the shading part 51 of the pot bottom temperature sensor 5 is comprised by the step part 73c1 formed in the taper shape of multistage, and it is located in the rising position of the pot bottom temperature sensor 5. As shown in FIG. Thus, no concave portion may be formed at the boundary between the through hole 33 and the pot bottom temperature sensor 5. As a result, when the burner is not in use, the flying products scattered by the pot bottom temperature sensor 5 do not stay at the boundary between the through hole 33 and the pot bottom temperature sensor 5, and the outside of the top surface of the burner cap 32. You can let it flow down.

In addition, as shown in FIG. 7, the shading part 51 of the pot bottom temperature sensor 5 may be comprised by the R-shaped step part 73c 'of which the outer side was convex. The flange member 6 shown in FIG. 5 may also have such an R shape.

In addition, the burner part 21 is not limited to what consists of the burner head 31 and the burner cap 32, They may be formed integrally.
