JP 2007-147275 A

  When adding a steam cooking function to a heating cooker, the side of the heating cooker often faces the wall or other household appliances so that the water tank can be pulled out and removed from the front. Since the upper surface of the container is often used as a place for placing articles, it can be said that the structure is inevitable. By the way, the water tank is often handed when the cooking device is transported. If the water tank is pulled out by something when the water cooker is being lifted by placing a hand on the water tank, the cooker that has become unsupported will fall and be damaged. If the fallen place is on a person's body, you must be prepared for injury.

  The present invention has been made in view of the above points, and in a heating cooker provided with a drawer-type water tank, even if the water tank is touched during transportation of the heating cooker, the water tank does not come out. The purpose is to be able to avoid various dangers caused by the water tank coming out.

To achieve the above object, according to the present invention, in a cooking device capable of supplying steam to a heating chamber from a built-in steam generator, a water tank for supplying water to the steam generator can be drawn from the front of the housing. An engagement portion including a protrusion is formed between the water tank and the housing, and is formed on one of the water tank and the housing when an upward force is applied to the water tank. The projected protrusion engages with the other of the water tank and the housing to prevent the water tank from being pulled out.

  Further, the present invention is the heating cooker having the above configuration, which is opposed to a substantially U-shaped cut groove formed in the housing wall facing the upper surface of the water tank, and a tongue piece portion surrounded by the cut groove. The protrusion formed on the upper surface of the water tank in the form of the engaging portion, and when the upward force is applied to the water tank, the protrusion excludes the tongue piece portion, and the protrusion And an engagement state occurs between the cut grooves.

According to the present invention, when the heating cooker is lifted for transportation, even if the water tank is touched, the upward force acting on the water tank is provided on one of the casing of the heating cooker and the water tank. Since the projected protrusion is engaged with the other of the heating cooker casing and the water tank, the heating cooker casing and the water tank are engaged, and the water tank is prevented from being pulled out. It is possible to avoid a situation in which the cooking device that has lost its support due to the tank falling out can be avoided, and the cooking device can be safely transported.

  Hereinafter, the structure of the heating cooker 1 which is embodiment of this invention is demonstrated based on figures.

  The heating cooker 1 includes a rectangular parallelepiped housing 10 configured by combining a sheet metal member and a synthetic resin molded member. A heating chamber (not shown) is provided inside the housing 10. The heating chamber has an opening on the front surface, and the opening is closed by the door 11. The door 11 rotates in the horizontal plane with the left end as a fulcrum.

  On the front surface of the housing 10, a portion corresponding to the right side of the door 11 is configured by a panel 12 that is a synthetic resin molded product. A display unit 13 made of a liquid crystal panel or the like is formed at the upper part of the panel 12, and an operation unit 14 having a plurality of operation keys (not shown) arranged at the lower part thereof. An opening 16 (see FIGS. 2 and 3) for inserting the water tank 15 into the housing 10 is provided below the operation unit 14. The water tank 15 is a pull-out type, and the handle portion 15a protrudes forward. A gap is provided between the upper surface of the water tank 15 and the ceiling portion of the opening 16 to allow the water tank 15 described later to move upward.

  The heating cooker 1 is capable of heating with high frequency, heating with hot air, heating with water vapor, and heating mixed with them. In order to implement | achieve it, the heating cooker 1 is provided with the element shown in FIG.

  The control unit 20 forms the center of control of the heating cooker 1. The control unit 20 is configured with a microcomputer as a core, receives output signals from various components, and outputs control signals to various components.

  The elements connected to the control unit 20 include the following in addition to the display unit 13 and the operation unit 14 described above. First, as elements for performing high-frequency heating, there are a high-frequency drive power source 21 that oscillates a magnetron (not shown) and an antenna motor 22 that rotates an antenna (not shown) that distributes high-frequency waves generated by the magnetron oscillation into the heating chamber. . As elements for heating with hot air, there are a convection heater 23 that turns air into hot air and a convection fan 24 that sends the hot air into a heating chamber and circulates it. As elements for performing heating with water vapor, a steam generating heater 25 that generates steam in a steam generator (not shown), a steam heating heater 26 that converts the generated steam into superheated steam, and water is supplied to the steam generator. There is a water supply pump 27. In addition, there is a cooling fan 28 that takes in cooling air from the outside inside the housing 10.

  Elements that output a signal to the control unit 20 include a temperature sensor 29 that measures the temperature inside the heating chamber, a humidity sensor 30 that measures the humidity inside the heating chamber, a water level sensor 31 that measures the water level inside the steam generator, and a door. There is a door opening / closing sensor 32 that detects that 11 is opened or closed.

  When the water tank 15 is inserted into the housing 10, the water tank 15 is connected to the water supply pump 27, and the water supply pump 27 sucks out water from the water tank 15 and supplies it to the steam generator. An engaging portion is formed between the water tank 15 and the housing 10, here the panel 12, which is engaged when an upward force is applied to the water tank 15. This will be described below with reference to FIGS.

  The engaging portion 40 is composed of an element formed on the panel 12 and an element formed on the water tank 15. Elements formed on the panel 12 are a substantially U-shaped cut groove 41 (see FIG. 6) formed in the horizontal wall 12 a facing the upper surface of the water tank 15, and a tongue piece portion 42 surrounded by the cut groove 41. is there. The tongue piece 42 has a shape in which the tip is directed toward the user. The tongue piece portion 42 is bent when a force is applied due to the elasticity of the synthetic resin that is a material of the panel 12 and is restored to the original shape when the force is removed.

  The element formed in the water tank 15 is a protrusion 43 formed on the upper surface of the water tank 15. The protrusion 43 is a side shape triangle, and the front surface is a vertical wall. The protrusion 43 is disposed so as to be directly below the tongue piece portion 42.

  When the water tank 15 is pushed into the opening 16, in the normal state, the engaging portion 40 is not engaged as shown in FIG. 5, and the water tank 15 can be pulled out without any trouble. However, when the heating cooker 1 is lifted for transportation, an upward force indicated by an arrow in FIG. 7 acts on the water tank 15 when the water tank 15, particularly the handle portion 15 a, is touched. As a result, the water tank 15 is lifted upward, and the protrusion 43 pushes up the tongue piece 42 and enters the opening remaining after the tongue piece 42 is removed.

  Even if the water tank 15 is pulled forward, the vertical wall on the front surface of the protrusion 43 engages with the cut groove 41, and the water tank 15 does not come out of the opening 16. That is, the water tank 15 is locked. Thereby, the situation that the heating cooker 1 which the water tank 15 slipped out and became unsupported can be avoided, and the safe cooking of the heating cooker 1 is attained.

  The engaging portion 40 includes a tongue piece portion 42 formed on the panel 12 by a substantially U-shaped cut groove 41 and a protrusion 43 formed on the upper surface of the water tank 15 so as to face the tongue piece portion 42. Therefore, it is not necessary to add another part, and it can be configured at a very low cost.

  When steam cooking is performed, a large amount of condensed water adheres to the back surface of the door 11 (the side facing the heating chamber). In order to treat the condensed water efficiently, the following structure is provided on the back side of the door 11.

  FIG. 8 shows the back side of the door frame 50 constituting the main part of the door 11. The door frame 50 is a synthetic resin molded product, and the front shape is rectangular. A window 51 is formed at the center of the door frame 50 to show the inside of the heating chamber. The window 51 is covered with a window glass made of heat-resistant glass and a radio wave leakage prevention screen (both not shown).

  A dew receiving bowl 52 is formed near the lower edge of the back surface of the door frame 50. The dew receiving bowl 52 inclines downward in FIG. 8 and has an outlet 52a at the right end. A water pan 53 is disposed under the outlet 52a. The water pan 53 constitutes a part of the front surface of the housing 10.

  Since the dew receiving bowl 52 has an inclination that decreases toward the outlet 52 a, the dew condensation water received by the dew receiving bowl 52 flows down quickly and is received by the water receiving pan 53. For this reason, dew condensation water stays on the back side of the door 11, and when the door 11 is opened, it does not drip out of the heating cooker 1. Even if the dew receiving bowl 52 is inclined in this way, it does not affect the shape of the door 11 viewed from the front, and does not impair the design.

  Although the embodiments of the present invention have been described above, the scope of the present invention is not limited to these embodiments, and various modifications can be made without departing from the spirit of the invention.

  The present invention can be widely used in heating cookers that cook using steam.
