Description

  The present invention relates to a range hood used in a kitchen.

  Conventionally, as described in Patent Document 1, for example, a range hood is known in which the entire inner surface of an air passage from the inlet of the fan case to the outlet of the fan case can be cleaned outside the range hood. .

  In the range hood described in Patent Document 1, the blower A itself including the fan case is configured to be detachable from the hood body, and at the time of cleaning, the blower A is removed from the hood body, and the fan case of the blower A is used in the kitchen. It can be cleaned in a large space. Thus, the entire inner surface of the air passage from the inlet of the fan case where the oil easily adheres to the outlet of the fan case can be cleaned.

Japanese Patent Laid-Open No. 11-311431

  However, since the blower A has a built-in motor for rotating the fan case, when removing the blower A, the motor for rotating the fan case must be removed. Further, in the range hood described in Patent Document 1, the inner surface of a part of the air path from the inlet to the outlet of the fan case is formed by the outer surface of the relatively large motor body attached to the fan case. Since it is formed, in order to clean the entire inner surface of the air passage from the inlet to the outlet of the fan case outside the range hood, it is essential to remove the motor.

  Normally, the wiring from the power supply is connected to the motor. When attaching or detaching the motor to or from the range hood, it is necessary to connect and remove such wiring from the motor. It takes time to install and remove. In addition, when removing the motor, the motor may be accidentally dropped, causing the motor to malfunction. Further, when the removed blower A is attached again, the connection work of the motor wiring may be forgotten and the fan may not operate.

  The present invention has been made in view of the above problems, and provides a range hood capable of cleaning substantially the entire inner surface of the air passage from the inlet to the outlet of the fan case outside the range hood without removing the motor. The purpose is to do.

  In order to solve the above problems, a range hood according to the present invention collects air containing oily smoke generated during cooking, and a hood body having a baffle that guides the collected air to the downstream side, and by rotation. A fan that generates an air flow so that the air flows downstream from the air guide port, a motor that drives the fan to apply a rotational force, and the air guide port that communicates with the air guide port so that the air flows downstream from the air guide port. An inflow port provided at a position facing the upstream end surface of the fan, and a fan case that has an exhaust port for discharging the air flowing in from the inflow port from the circumferential direction to the outside, and houses the fan therein, The fan case is configured to cover an outer peripheral surface and a downstream end surface of the fan with an air passage forming wall that forms an air passage from the inlet to the outlet. The hood body is formed in a size that allows the fan case to be taken in and out of the hood body, and further, a fan case mounting portion to which the fan case is attached, and a fan case. And a motor mounting portion to which the motor is attached. The motor is attached to the motor mounting portion provided outside the fan case, and the fan case is the fan. It is characterized by being detachably attached to the case attaching portion.

In the range hood according to the present invention, the fan case is configured to cover the outer peripheral surface and the downstream end surface of the fan with an air passage forming wall that forms an air passage from the inlet to the outlet. Therefore, since almost the entire inner surface of the air passage is constituted by the inner surface of the air passage forming wall, a part of the air passage from the inlet to the outlet of the fan case is caused by the outer surface of the motor body as in the prior art. It is never formed. And the oil of the air which flowed in from the inflow port of a fan case adheres to the inner surface of this air path formation wall.
The motor is attached to a motor mounting portion provided outside the fan case, and the fan case is detachably attached to the fan case mounting portion. Therefore, when cleaning the entire inner wall of the air passage from the inlet to the outlet, remove only the fan case from the fan case mounting part and remove it from the air inlet of the hood body. It is possible to clean substantially the entire inner surface of the air passage from the outlet to the outlet. For this reason, it is not necessary to remove a motor like the past.
Therefore, according to the range hood of this invention, it becomes possible to wash | clean the whole air path inner surface from the inflow port of a fan case to an outflow port outside a range hood, without removing a motor.

  Moreover, in the range hood which concerns on this invention, it is also preferable that the said fan case is comprised so that it can remove from the said fan case attaching part with the shape at the time of being attached to the said fan case attaching part.

  In this preferred embodiment, the fan case is configured so that it can be removed from the fan case mounting portion while maintaining the shape when attached to the fan case mounting portion. Therefore, when the fan case is removed, the shape of the fan case is changed. At least, the fan case can be removed, so that the workability of removing the fan case can be improved.

  According to the range hood of the present invention, it is possible to clean substantially the entire inner surface of the air passage from the inlet to the outlet of the fan case outside the range hood without removing the motor.

Specifically, although not shown in FIG. 1, the upper portion of the fan case mounting housing 5 has a protruding portion 5 e that protrudes upward and has substantially the same cross section as the shape of the top plate 7 k of the fan case 7. A plurality of leaf springs 5d extending from the end of the upper surface of the protrusion 5e to the side wall are fixed to the upper surface of the protrusion 5e with screws. The leaf spring 5d has a protrusion 5da at its tip, and the protrusion 5da protrudes into the protrusion 5e from a hole 5f provided in the side wall of the protrusion 5e. A plurality of grooves 7e that engage with the protrusions 5da are provided in the upper part of the side peripheral plate 7h of the fan case 7, and a leaf spring that applies an inward pressing force to the plurality of grooves 7e. By engaging the protrusion 5da of 5d, the side peripheral plate 7h is sandwiched between the plurality of spring plates 3f, whereby the fan case 7 is attached to the fan case attachment housing 5. When the fan case 7 is removed, a force for lowering the fan case 7 is applied to overcome the pressing force applied from the leaf spring 5d, so that the protrusion 5da of the leaf spring 5d is removed from the groove 7e of the fan case 7. The fan case can be removed. In this way, the fan case 7 is detachably attached to the fan case attachment housing 5.

  A concave portion 5c for attaching the motor 11 and a motor insertion hole 5g for inserting the motor 11 are provided on the upper surface of the protruding portion 5e. The motor 11 has a mounting flange extending radially outward from the motor body 11a. The motor 11 is mounted on the fan case mounting housing 5 by fixing the mounting flange 11b to the bottom surface of the recess 5c with a screw or the like (not shown).

Yes. A rotation shaft insertion hole 7f for inserting the rotation shaft 12 of the motor 11 is provided on the bottom surface of the second recess 7d.

  In a state where the fan case 7 is mounted on the fan case mounting housing 5, the recess 5c enters the first recess 7c, and the lower portion of the motor body 11a of the motor 11 enters the second recess 7d. . Accordingly, the first hollow portion 7c and the second hollow portion 7d cover and hide the motor body 11a and the recess 5c of the protruding portion 5e.

  In a state where the fan case 7 is attached to the fan case attachment housing 5, the rotating shaft 12 attached to the motor 11 extends downward from above in the fan case 7. A rotating shaft mounting portion 9a at the center of the fan 9 is detachably connected to the tip of the rotating shaft 12.

  Next, the structure of the fan case 7 will be described in more detail. FIG. 4A and FIG. 4B are a perspective view of the fan case 7 viewed from the lower surface and a perspective view viewed from the upper surface, respectively. The fan case 7 has a bottom plate 7g, a side peripheral plate 7h, and a top plate 7k, which are integrally formed. The bottom plate 7g is provided with an inflow port 7a, and the side peripheral plate 7h is provided with an outflow port 7b. The inflow port 7a is formed at a position facing the upstream end surface 9b (see FIG. 2) of the fan 9 and has a diameter larger than the diameter of the fan 9, and the fan 9 is removed from the inside through the inflow port 7a. Can be taken out. The top plate 7k is provided so as to cover the motor body 11a of the motor 11 and the upper part of the fan case mounting housing 5. Therefore, substantially all the air passage 8 from the inlet 7 a to the outlet 7 b of the fan case 7 is formed by the inner surface of the fan case 7. That is, the bottom plate 7 g, the side peripheral plate 7 h, and the top plate 7 k of the fan case 7 form an air passage forming wall that forms the air passage 8. The side peripheral plate 7h and the top plate 7k are configured to cover the outer peripheral surface 9c and the downstream end surface 9d of the fan 9, respectively.

  As described above, since the air passage 8 from the inlet 7a to the outlet 7b of the fan case 7 is almost entirely formed by the inner surface of the fan case 7, the entire inner surface of the air passage 8 is wide open space outside the range hood 1. In the case of cleaning with, for example, it is sufficient to remove the fan case 7, and it is not necessary to remove the motor 11 as in the prior art.

  Subsequently, a process of removing the fan case 7 will be described. FIG. 5 is a perspective view showing how the fan case 7 is removed.

  When removing the fan case 7, first, the current plate 21 is removed, and then the oil pack 23 is pulled downward to remove the oil pack 23. Then, after removing the fan 9 which is detachably attached to the rotating shaft 12, the fan case 7 which is detachably attached to the fan case attaching housing 5 is pulled downward (force is applied downward) to attach the fan case. Remove from the housing 5. When the fan case 7 is removed, the fan case 7 can be removed from the fan case mounting housing 5 with the same shape as when the fan case 7 is attached to the fan case mounting housing 5.

  The user can remove the fan case 7 in this way and wash the fan case 7 outside the range hood 1. Further, when the fan case 7 is attached to the fan case mounting housing 5, the inner surface of the fan case mounting housing 5 is covered with the fan case 7, so that a hand is inserted into the fan case mounting housing 5 during cleaning. Thus, there is no need to perform an operation of cleaning the inner surface of the fan case mounting housing 5. Therefore, it is possible to save the user from having to clean the fan case mounting housing 5 at a high position. In addition, after washing | cleaning the fan case 7, what is necessary is just to attach components to the range hood 1 in the reverse process to the process mentioned above.
