3 is a cleaning pump that circulates cleaning water in the cleaning tank 2, and is rotationally driven by a cleaning pump motor. Reference numeral 6 denotes a leftover filter installed at the bottom of the cleaning tank 2. The cleaning water sucked from the leftover filter 6 is pressurized by the cleaning pump 3, and is ejected from the nozzle 6, which is located at the top of the nozzle/l/6. Then, the tableware 8 placed in the tray 7 is washed. At this time, the cleaning water is heated by a heater 9 disposed at the inner bottom of the cleaning tank 2. When washing or rinsing is completed, the washing water is drained, and then the exhaust fan motor 10 located at the rear of the main body 1 drives the exhaust fan 1OA to blow outside air into the washing tank 2, and the heater 9 removes the dishes 8 and the washing tank. The temperature of the gas inside the cleaning tank 2 is increased to promote the evaporation of water droplets adhering to the inside of the cleaning tank 2 and the dishes 8, and the water vapor inside the cleaning tank 2 is released from the exhaust air 012 of the lid 11, which is provided in the front of the cleaning tank 2 so as to be openable and closable. Drying is performed by draining. 13 is an intake filter provided on the rear surface of the main body 1. 14 is a ventilation duct communicating with the cleaning tank 2.

Problems to be Solved by the Invention According to the conventional configuration, since the intake filter 13, exhaust fan 10a1 fan motor 10, and ventilation duct 14 are provided at the rear of the main body 1, the following problems arise.

(1) Since the component parts are located on the rear surface of the cleaning tank 2, the depth of the cleaning tank 2 had to be reduced if the dimensions of the main body 1 were kept constant.

(2) Since the intake filter 13 is located on the rear surface of the main body 1,
In a tabletop dishwasher in which small items such as seasonings and pots are frequently placed on the top surface of the main body 1, it is difficult to attach and detach the intake filter 13 and to clean it.

(3) Since the rear surface of the intake filter 13 cannot be brought into direct contact with the wall surface, it is necessary to shift the product forward and install it, which unnecessarily increases the installation area.

(4) Since the intake filter 13 is located at the rear, when built into a so-called under-counter, the intake filter cannot be attached or removed, making it impossible to deploy the product in various installation spaces.

The present invention solves the above problems, and aims to provide a dishwasher that maximizes the effective space in the washing tank without changing the external dimensions of the product, and that can be adapted to various installation environments. shall be.

Means for Solving the Problems In order to achieve the above object, the first technical means of the present invention is to provide a washing tank for storing tableware therein, a frame for supporting the lower part of the washing tank, and a frame for supporting the lower part of the washing tank. The frame has an intake passage that is open to the outside of the machine via an intake filter at one end and communicates with the cleaning tank via a ventilation duct at the other end, and an exhaust fan is arranged inside the intake passage. be.

The second technical means is that the intake passage is constructed of a downwardly open recess formed in the underframe and a member that covers the open portion of this recess.

Further, the third technical means is that the intake filter is disposed in the front part of the intake passage, and the intake filter is configured to be able to be pushed out from the front side of the device and has the intake surface on the bottom or front side. .

Furthermore, a fourth technical means is that the exhaust fan is a sirocco fan having a central axis of rotation in the horizontal direction.

Effects According to the first technical means, since the intake passage and the exhaust fan are arranged on the lower surface of the main body, the depth of the cleaning tank can be increased. In addition, in the second technical means,
An intake passage can be easily formed by forming a recess in the underframe and using a member that covers the recess.

In addition, according to the third technical means, the intake filter can be attached and detached to the front of the device, and the ease of attaching and detaching the intake filter is not impaired even when it is installed in the under counter or when something is placed on the top of the device. Because there is no such thing, it can be used in various installation environments. Furthermore, according to the fourth technical means, since a fan having a rotation center axis in the horizontal direction is used, the fan is placed on the shaft of the cleaning pump motor having a rotation center axis in the horizontal direction, and a new fan is installed. There is no need to provide a motor, allowing for much smaller size.

EXAMPLE Hereinafter, an example of the dishwasher of the present invention will be explained based on FIG.

In the figure, 16 is a cleaning tank provided inside the main body 16, and a cleaning pump 17 (motor not shown) for circulating cleaning water is provided at the bottom.

Reference numeral 18 denotes a waste filter installed at the bottom of the washing tank 16. The washing water sucked through the waste filter 18 is pressurized by the washing pump 17, and is ejected from the nozzle 19.
Washing water is heated by a heater 22 when washing the tableware 21 placed in the washing machine.

Reference numeral 23 denotes an underframe molded from synthetic resin, which supports the lower part of the cleaning tank 16 and has a substantially downwardly open concave portion 23a formed on its lower surface, and is a member that covers the concave portion 23a of the underframe 23 from below. 24 and the recess 23a constitute an intake passage 26. A partition plate 2 is installed inside this intake passage 25.
7 is arranged to form a fan casing 3e, and an exhaust fan 26 is arranged inside this fan casing 36.
Reference numeral 8 denotes a fan motor, and its rotating shaft is arranged in the vertical direction. An intake filter 29 is detachably attached to the front surface of the frame 23 constituting the intake passage 26 from the front, and its intake surface 30 is provided on the lower surface of the frame 23. Needless to say, the intake surface 30 may be provided in the front, depending on the collection area of the intake filter 29 or the product configuration.

Reference numeral 31 denotes a ventilation duct that communicates a fan casing 36 formed in the middle of the intake passage 25 with the cleaning tank 16. 3
Reference numeral 2 denotes a lid provided at the front opening of the cleaning tank 16 so as to be openable and closable, and an exhaust port 33 is provided at the top.

The leg portion 34 is a back plate.

According to the above configuration, when the heater 22 is energized and the exhaust fan 26 is operated in the drying process, outside air is guided into the intake passage 26 through the intake filter 29,
The air is discharged into the cleaning tank 16 through the air duct 31. Moreover, in order to facilitate integral molding of the ventilation passage 26 to the underframe, a recess 23a is formed on the lower surface, and since the exhaust fan 26 is disposed within the recess 23a, a ventilation duct 31 is provided on the rear side. All you need is cleaning tank 1.
In this example, a vertical centrifugal fan is shown as an example, but depending on the configuration of the aircraft, a horizontal scirocco fan with a horizontal rotation center axis may be used. can have a similar configuration, and in this case, it can be attached to the motor 4 having a horizontal drive shaft as shown in FIG. Effects As is clear from the above embodiments, according to the present invention, since the intake passage and the exhaust fan are arranged on the bottom surface of the main body, the depth of the cleaning tank can be increased without changing the external dimensions of the main body. Furthermore, the intake passage can be easily formed by forming a recess in the underframe, making it suitable for mass production. In addition, since the intake filter can be attached and removed from the front of the main body, not only does it improve the operability of the filter, but when it is installed on top of a sink, the main body can be placed in close contact with the rear wall, which was difficult to do in the past. It can be installed in a variety of installation formats, such as being able to be installed under the counter (on the side of the sink metalwork), thereby reducing overall installation space, increasing diversification, increasing cleaning capacity, and improving operability. Furthermore, if a sirocco fan having a rotation center axis in the horizontal direction is used, the cleaning motor can also be used as a fan motor, making it possible to further downsize the device.
