JP 2006-234370 A

  By the way, in the conventional built-in type gas stove, a defective portion which is a trace of a vertical portion is present in the horizontal portion of the sensor mounting portion. Further, the missing portion in the horizontal portion is present on the side where the spark plug is present (see FIGS. 1, 2, 5, and 7 (particularly FIG. 2) of Patent Document 1).

  Further, the stove burner in the built-in gas stove of Patent Document 1 includes a through-hole that vertically penetrates the center thereof, and a temperature detection device (temperature detection sensor) is disposed in a manner that vertically penetrates the through-hole. ing.

  Moreover, in the case of a built-in type gas stove including the built-in type gas stove disclosed in Patent Document 1, usually, a gas cooker body is inserted into an opening provided in a kitchen counter from above, and a flange formed around the gas stove body is provided. After the gas stove is installed in the opening provided in the kitchen counter in a manner of locking around the opening, the top plate is mounted so as to cover the upper surface of the gas stove main body.

  Further, the lower area (space) of the kitchen counter is often used as a storage, and recently, the storage area has a storage rack configured to slide in the front-rear direction with a slide rail. There are many.

  And the storage rack which comprises the front panel part of a kitchen counter is provided in the front side of the storage rack, and the storage rack is pulled out to the front drawer position by pulling this door forward. Many are configured in this manner, that is, a configuration having a so-called slide storage.

  In the case of a slide storage, when the closed storage door is pulled forward, the storage rack and the storage items stored in the storage rack are pulled out of the storage. It is easy to use and can be easily removed.

  However, when the closed storage door is pulled forward, the pressure (atmospheric pressure) inside the storage becomes lower than the pressure (atmospheric pressure) outside the storage.

  Generally, when the pressure inside the storage (atmospheric pressure) is lower than the pressure outside the storage (atmospheric pressure), the stove of the stove burner is above the top plate and the stove of the stove burner is The pressure (atmospheric pressure) at the location is the same as the pressure (atmospheric pressure) outside the storage.

  On the other hand, since the area where the gas stove body is located communicates with the space where the storage rack in the storage is located, the pressure (atmospheric pressure) where the gas stove body is located is the place where the flame burner of the stove burner is located. Lower than the pressure (atmospheric pressure).

  That is, generally, the gas stove body is formed in a box shape by bending a metal plate such as a plated steel plate, and there is a gap at the joint between the metal plate and the metal plate. If the pressure (atmospheric pressure) at the location is lower than the pressure (atmospheric pressure) at the location where the built-in type gas stove stove is located, the pressure inside the gas stove will be the pressure at the location where the stove is located. Lower.

  When the pressure in the gas stove main body becomes lower than the pressure at the location where the burner of the stove burner is located, the gas in the vicinity of the gas stove enters the gas stove main body from the through hole that penetrates the temperature detecting device (temperature detection sensor) of the stove burner. (Air) will flow in.

  The gas flowing into the gas stove main body 2 from the central through-hole of the stove burner is a gas mixed with air heated by the combustion heat of the stove burner, high-temperature combustion exhaust gas of the stove burner, and the like. It is normal.

  Therefore, as in the built-in gas stove of Patent Document 1, when a defective portion in the sensor attachment portion for attaching the temperature detection device (temperature detection sensor) exists on the ignition plug side, a high voltage is applied to the ignition plug. For example, the high-temperature gas (air) described above passes through the periphery of the high-pressure cord, and there is a risk that the high-pressure cord having a rubber-based coating may be damaged and the reliability is low. There is a point.

  The present invention solves the above-mentioned problem, and even when the pressure (atmospheric pressure) at the location where the gas stove body is located becomes lower than the pressure (atmospheric pressure) at the location where the stove of the stove burner is located, the gas stove A highly reliable built-in gas stove that can prevent high-temperature gas flowing into the main body from passing near the high-pressure cord in the gas stove body and prevent the high-pressure cord from being damaged.

In addition, in FIG. 4, illustration of the fixing tool for fixing the temperature detection apparatus 18 is abbreviate | omitted.

  In the present embodiment, the missing portion 20c, which is a trace of the vertical portion 20b cut from the horizontal portion 20a, is connected to the lower end side of the spark plug 30 and the spark plug 30 in the temperature detection device mounting portion 20. The high-voltage cord 40 is configured to be positioned in the region Q on the other end side opposite to the region P on the one end side (FIGS. 3 and 4).

  That is, the spark plug 30 and the high-voltage cord 40 have a region P on one end side where the horizontal portion 20a is present opposite to the region Q on the other end side where the missing portion 20c is present in the temperature detection device mounting portion 20 in plan view. It is comprised so that it may be located in.

  In the present embodiment, as described above, the temperature detection device mounting portion 20 is formed by raising the vertical portion 20b from the horizontal portion 20a of the integral metal plate. It can be easily formed, and the manufacturing cost can be reduced.

  Further, in the built-in type gas stove A according to the present embodiment, the tip portion which is the end portion of the horizontal portion 20a of the temperature detection device mounting portion on the side where the spark plug 30 and the high-voltage cord 40 are present (one region P side). In addition, a dam portion 21 is extended upward (FIGS. 3 and 4).

  And in the built-in type gas stove A of this embodiment, the dam part 21 is located in the boundary part of the upper dam part 21a located in an upper side, the upper dam part 21a, and the horizontal part 20a, and it ignites as it goes below. An inclined weir portion 21b is provided so as to be inclined so that the distance from the connection portion between the lower end of the metal shaft body 32 constituting the plug 30 and the high-voltage cord 40 increases.

  That is, in the built-in type gas stove A of this embodiment, the dam part 21 is comprised from the inclination dam part 21b following the horizontal part 20a, and the upper dam part 21a.

  In this embodiment, the upper dam portion 21a is substantially vertical, but the upper dam portion 21a is inclined such that the inclined dam portion 21b has an angle smaller than the angle that the inclined dam portion 21b has with respect to the vertical surface. It is also possible to configure such that

  The built-in type gas stove A according to the present embodiment includes the inclined dam portion 21b, so that the shortest distance Y between the connection portion of the ignition plug 30 and the high-pressure cord 40 and the inclined dam portion 21b is reduced to the ignition plug 30.

  As described above, in the built-in type gas stove A according to the present embodiment, the temperature detection device mounting portion 20 is formed by raising the vertical portion 20b from the horizontal portion 20a of the integral metal plate. The attachment portion 20 can be easily formed, and the manufacturing cost can be reduced.

  Moreover, since the dam part 21 is integrally formed from the metal plate together with the horizontal part 20a and the vertical part 20b described above, the manufacturing cost can be reduced.

  The built-in type gas stove A according to the present embodiment is configured as described above, and since the defect portion 20c is not formed in the region P on the one end side of the temperature detection device mounting portion 20, the gas stove main body 2 is positioned. Even when the pressure (atmospheric pressure) of the place where the gas flows is lower than the pressure (atmospheric pressure) where the flame outlet 4 of the stove burner 3 (3a, 3b) is located, the through-hole 13 that penetrates the center of the stove burner vertically The high-temperature air that has flowed into the gas stove main body through the spark plug side is suppressed by the horizontal portion 20a and the dam portion 21, and the pressure (atmospheric pressure) at the location where the gas stove main body is located is the stove 4 of the stove burner. Even when the pressure (atmospheric pressure) is lower than the location where is located, the high-temperature cord is prevented from being damaged by the high-temperature air that has flown in the vicinity of the high-pressure cord. Rukoto can.

  Incidentally, an air inlet 14 (FIG. 1) for taking air into the gas stove main body from outside the storage is formed on the front surface of the gas stove main body so as to be exposed to the outside of the storage, and the pressure ( Pressure) is equal to the pressure (atmospheric pressure) at the location where the stove 4 of the stove burner is located. Therefore, the pressure (atmospheric pressure) at the location where the gas stove body is located is equal to the pressure (atmospheric pressure) at the location where the stove 4 of the stove burner is located. When it becomes lower, air flows into the gas stove main body from the intake port 14, but as described above, the gas stove main body 2 also from the through-hole 13 that penetrates the center of the stove burner 3 (3 a, 3 b) up and down. Hot gas (air) flows into the inside.

  For this reason, in the case of a built-in type gas stove that does not include the temperature detection device mounting portion having the above-described characteristic configuration of the present invention (for example, the built-in type gas stove of Patent Document 1), the high-pressure cord having a rubber coating is damaged. Will end up.

  Thus, according to the present invention, damage to the high-pressure cord due to the inflow of high-temperature gas from the through-hole 13 of the stove burner 3 (3a, 3b), which may occur in the case of a conventional built-in gas stove, is ensured. Can be suppressed.

  Further, since the dam portion 21 is extended, the pressure (atmospheric pressure) at the location where the gas stove body 2 is located is lower than the pressure (atmospheric pressure) at the location where the flame mouth 4 of the stove burner 3 (3a, 3b) is located. When this happens, high-temperature gas (air) passing through the upper surface of the horizontal portion 20a of the temperature detection device mounting portion 20 is prevented from flowing to the region P side where the spark plug 30 and the high-pressure cord 40 are disposed. Therefore, it is possible to more reliably suppress and prevent the high-voltage cord from being damaged.

  Furthermore, the dam part 21 is located at the boundary between the upper dam part 21a located on the upper side and the upper dam part 21a and the horizontal part 20a, and the metal shaft body 32 constituting the ignition plug 30 is directed downward. It is configured to include an inclined weir portion 21b that is provided so as to be inclined so that the distance from the connection portion between the lower end and the high-pressure cord 40 is increased, and the connection portion between the spark plug 30 and the high-pressure cord 40; Since the shortest distance Y between the inclined weir portion 21b is configured to be larger than the distance X between the upper end of the metal shaft body 32 constituting the spark plug 30 and the target 6, the spark plug 30 Suppressing leakage discharge from the connecting portion of the high-voltage cord 40 to the dam portion 21 of the temperature detection device mounting portion 20 and accurately discharging between the upper end of the metal shaft body 32 of the spark plug 30 and the target 6. Let It becomes possible. As a result, it is possible to provide a highly reliable built-in type gas stove having good ignition performance.

  In the above embodiment, the case where the dam portion 21 is provided and the dam portion 21 is provided with the upper dam portion 21a and the inclined dam portion 21b has been described as an example. However, the built-in gas stove according to the present invention is illustrated in FIG. As shown in FIG. 6, it is possible to adopt a configuration in which the dam portion 21 is not provided. Moreover, as shown in FIG. 6, it is also possible to comprise the dam part 21 so that it may become a flat part bent so that it may have a predetermined angle with respect to the horizontal part 20a.
