Description

[Detailed description of the invention] Industrial application field The present invention relates to air conditioning equipment such as oil hot air heaters.

Conventional Structure and Problems Generally, an air conditioning fan is used in an air conditioner, and a filter is provided at the suction port of the fan. This filter is removable so that it can be cleaned when it becomes clogged, and is usually removed by pulling it upward or forward. However, in the conventional type, as shown in Fig. 9, when the main body A of the device is used inside a mantelpiece, the filter B is moved to the arrow I.
There were problems such as being unable to take out the paper in the same direction or making it extremely difficult to take out. In addition, if the filter is provided near the bottom of the main body of the device, it is possible to build it into a mantel, etc., but there are problems such as a lot of dust such as cotton dust and clogging of the filter.

Purpose of the invention This invention was created in view of the above points.
The purpose is to allow the filter to be easily removed.

Structure of the invention In order to achieve this objective, the present invention provides an air suction port near the rear edge of the device body covered with a front plate, and connects an arc-shaped filter through guide portions provided on both sides of the air suction port. is removably arranged, and the entrance of the guide section is provided at the back edge of the device body, so that the filter can be freely pulled out toward the front side along the top or side surface of the device body without removing the front plate. At the entrance of the guide section, a position correction member having two tapered parts for correcting the misalignment of the filter in two directions, front and back and left and right, is installed, and the upper part of this position correction member is placed above the top surface of the main body of the device. Alternatively, it may protrude laterally from the side.

DESCRIPTION OF THE EMBODIMENTS An embodiment of the present invention will be described below using a hot air heater as an example. In Figs. The exchange unit consists of a combustion section 3 and a heat exchange section 4. Reference numeral 5 denotes a cross flow fan (this may be a Sirotskov fan or the like) installed above the heat exchange unit 2, and the air from this fan 5 is converted into warm air by the heat exchange unit 2. Hot air is blown out of the machine from a hot air outlet 6 provided at the lower part of the front panel of the main body 1 of the device. Reference numeral 7 denotes an air suction port provided in the upper part of the back plate of the device body 1 facing the suction port of the fan 5, and is formed by recessing the vicinity of the upper edge of the back plate 1a inward. Approximately half of the upper half of both sides of the recessed portion 7a forming the air suction port 7 are formed in an arc shape as shown in the drawing, and a guide portion 8 having a substantially U-shaped cross section and an arc shape is formed. be. 9 is an air suction port 7 along this guide part 8.
The filter is provided on the front surface of the filter, and is constructed by forming a breathable member such as a wire mesh into an arc shape similar to the guide section 8, and is set so that it can be taken in and out along the guide section 8.

Here, since the filter 9 is formed in an arc shape, when you hold the handle 9a and pull it out as shown by the arrow a in FIG. The front side along 1b,
That is, it is pulled out to the front side of the device main body 1. Therefore, for example, as shown in the figure, the device main body 1
Even if the filter 9 is set in the mantelpiece, the filter 9 can be easily taken out from the front side of the device body 1. Moreover, since the filter 9 can be freely inserted and removed along the guide portions 8 provided on both sides of the air suction port 7, there is an advantage that the filter 9 can be reliably attached and detached.

In addition, in this embodiment, since the correction members 10 and 11 are provided at the insertion opening of the guide part 8 of the filter 9, the filter 9 is inserted into the guide part 8 with its tapered part KL corrected for longitudinal and horizontal positional deviations. be done. The correction members 10 and 11 are formed in a symmetrical shape and fit on the left and right sides of the filter 9.
The filter 9 can be easily taken in and taken out. Moreover, since the upper parts 10a and 11a of the correction members 10 and 11 are made to protrude upward from the upper surface of the apparatus main body 1, even if the filter 9 is built in as shown in FIG. It can be easily installed from the front side.

In the above embodiment, the filter 9 was explained as being able to be pulled out along the top surface 1 of the device body 1, but it is also possible to make it so that it can be pulled out along the side surface 1c of the device body 1. , and the same applies even if the device is an air conditioner other than a hot air heater, such as a cooler.

Effects of the invention As is clear from the above description of the embodiments, the present invention allows the filter to be taken in and out without removing the front panel of the main body of the device, which not only makes it easy to put on and take off the filter, but also to correct the position of the filter. By providing the member at the entrance of the guide portion of the filter, visibility of the mounting position from the front can be improved. Further, as in the above embodiment, the tapered portions K on the inside of the position correction members 10 and 11 can correct misalignment not only in the front and back but also in the left and right directions, and the filter can be inevitably guided toward the center, allowing the filter to be easily inserted into the guide portion 8. 9 can be installed. Furthermore, since the upper part of the position correction member protrudes above the top surface of the device body or laterally from the side surface, the filter can be easily installed by looking at the top even if the device body is installed built-in. Note that since the guide member is made of a resin with good sliding properties such as ABS resin or Teflon resin, the filter 9 can be easily attached and detached, making it easy to use.
