FIG. 3 shows a configuration example of a laundry processing liquid supply unit that supplies a laundry processing liquid such as a detergent or a softener on the left side of the upper surface of the outer frame. FIG. In the following description, the vertical and horizontal directions are based on the vertical and horizontal directions shown in FIG.

  An outer frame 2 composed of a steel plate and a resin molded product is placed on the upper part of the base 5 to form a casing 1 of the washing machine. A lid 3 and a front cover, which are doors for taking in and out the laundry, are provided on the front of the outer frame 2, and a back cover is provided on the back.

  A water tub 6 is provided inside the housing 1, and a laundry processing liquid supply unit 4 that supplies a laundry processing liquid into the water tub 6 is provided on one side (left side in the drawing) of the housing 1.

  In this embodiment, an example of a drum-type washing machine in which laundry is put in the water tank 6 and a cylindrical rotating drum that performs washing and dewatering is provided will be described.

  A water faucet is provided on the upper surface in the vicinity of the back surface of the casing 1 of the washing machine, and a water pipe is connected to supply water to the casing 1 that is the main body of the washing machine. Since the configuration is the same as that of a conventional washing machine or washing / drying machine, a detailed description is omitted.

  As shown in FIG. 3, the laundry processing liquid supply unit 4 has a tank tray 12 that holds a laundry processing liquid such as a detergent in advance, and an automatic unit that automatically puts a predetermined amount into the water tank 6 from the tank tray 12. In addition to the automatic feeding unit 13, a manual loading unit 9 for manually loading the laundry processing liquid is provided separately from the automatic.

  As an example, the tank tray 12 includes a detergent tank 7 that is a first tank that holds a detergent that is a first washing treatment liquid in advance, and a second tank that holds a softener that is a second washing treatment liquid in advance. And a softener tank 8 that can be installed. The tank tray 12 is provided with a tank lid, and the detergent tank 7 and the softener tank 8 can be pulled upward from the opening where the tank lid is opened, and can be set again. In the following description, the common configuration of the softener tank 8 and the detergent tank 7 may be simply referred to as “tank”. Details of the tank structure will be described separately.

  The manual loading unit 9 is provided with a detergent loading unit 10 into which a detergent manually loaded into the water tank 6 is loaded, and a softener loading unit 11 into which a softening agent is loaded. The introduced detergent and softener are supplied through a water supply pipe at a predetermined point in the washing process, and are supplied together with water into the water tank 6 through the detergent supply pipe.

  In this embodiment, since the washing processing liquid charging unit 4 is provided on the upper surface of the washing machine casing 1, it is not necessary for the user to bend in order to attach and detach the tank, and an easy-to-use washing machine can be provided. Further, since both the manual loading unit 9 and the automatic loading unit 13 are disposed on the left side of the upper surface of the casing 1 of the washing machine, the manual loading unit 9 and the automatic loading unit 13 are arranged in a unified position, so that user convenience is further improved. In addition, when the automatic charging unit 13 and the tank tray 12 are disposed below the water tank 6, there is a possibility that water may flow backward from the pipe connecting the automatic charging unit 13 and the water tank 6 to the automatic charging unit 13. In the embodiment, since the automatic charging unit 13 and the tank tray 12 are disposed above the water tank 6, there is no fear of such a backflow, and a highly reliable washing machine can be provided. In addition, since the tank in the tank tray 12 can be inserted and removed from the top surface of the housing 1 in the vertical direction, usability is improved.

  Next, the configuration of the tank held in the tank tray 12 will be described with reference to FIGS.

  FIG. 4 is a view in which a detergent tank 7 as a first tank and a softener tank 8 as a second tank are held in a tank tray 12, and FIG. It is a figure.

  Below the tank tray 12, a convex positioning convex portion 14 is provided on the upper side so that the detergent tank 7 and the softener tank 8 are stably held. The positioning projection 14 makes it clear which position the detergent tank 7 and the softener tank 8 should be installed in the tank tray 12, and is stable without shifting in the tank tray 12. Can be retained.

  Further, a first connection portion 22 and a second connection portion 23 are provided on the lower side of the tank tray 12, and these two connection portions are connected to the first nozzle 15 and the second nozzle for supplying the washing treatment liquid into the water tank 6. Connected to the nozzle 16. The first nozzle 15 is connected to the first supply port 17 provided at the lower end of the detergent tray 7 as it is, and the second nozzle 16 is the second supply port provided at the lower end of the softener tray 8. The detergent and softening agent held in each tank are introduced into the water tank 6 from the respective supply ports via nozzles.

  The configuration of the detergent tank 7 and the softener tank 8 will be described with reference to FIGS.

  The detergent tank 7 and the softener tank 8 are provided with a handle 19 that is a tank handle so that the detergent tank 7 and the softener tank 8 can be easily inserted and removed from the top surface of the housing 1 in the vertical direction. When the tank is stored in the tank tray 12, the handle 19 is stored by being tilted to the side of the tank. When stored, the handle 19 is stored on the side opposite to the adjacent side, that is, the handle 19 of the detergent tank 7 is stored on the side opposite to the side where the softener tank 8 is disposed, The handle 19 of the tank 8 is stored on the side surface opposite to the side where the detergent tank 7 is disposed. By doing in this way, when opening the lid of each tank, the handle of the adjacent tank does not get in the way, and the lid can be smoothly opened and the tank can be replenished with detergent or softener.

  As shown in Fig. 4, there are two tanks that can be washed using different washing treatment liquids such as detergents and softeners. However, depending on the laundry and the user's preference, the softener is not used. In some cases, only detergent is used.

  An example of a tank in the case of washing with one washing treatment liquid will be described with reference to FIG.

  In the case of using only one laundry processing liquid, for example, a detergent without using two laundry processing liquids, a third amount is retained so as not to be replenished many times, that is, a volume larger than the detergent tank 7 in FIG. A detergent tank 20 is provided as a tank. At that time, changing the tank tray 12 depending on the type of washing liquid and the number of tanks increases the cost and is troublesome for the user. Accordingly, the tank tray 12 is not changed, so that it can be used with either two or one tank.

  The configuration of the BB cross section of FIG. 8 is FIG. 9, and the configuration of the washing tank 20 is FIG. As shown in FIGS. 9 and 10, a recess 21 is provided below the detergent tank 20 at a position corresponding to the positioning protrusion 14 of the tank tray 12. By providing the recess 21, it is clear which position the one detergent tank 20 should be installed with respect to the tank tray 12, and can be stably held without being displaced in the tank tray 12. .

  Further, similarly to FIG. 5, a first supply port 17 is provided below the detergent tank 20, and connected to the first nozzle 15, the detergent stored in the detergent tank 20 is put into the water tank 6. At this time, the detergent tank 20 is not connected to the second nozzle 16 or the second connection part 23 of the tank tray 12, or the detergent that is the first washing treatment liquid is not discharged to the second connection part 23. This is because it is necessary to largely change the control of the input amount of the washing processing liquid in the automatic charging unit 13 between two tanks and one tank. However, if the control of the amount of laundering treatment liquid in the automatic charging unit 13 can be largely changed between the case of two tanks and the case of one tank, even if one tank is provided, two supply ports are provided and two tanks are provided. As in the case of one, it may be connected to two nozzles.

  In the case of one tank, as in the case of two tanks, a handle 19 that is a tank handle is provided because it can be easily inserted and removed from the top surface of the housing 1 in the vertical direction. When the tank is stored in the tank tray 12, the handle 19 is stored by being tilted to the side of the tank.

  As described above, according to the present invention, it is possible to provide a washing machine capable of realizing a combined tank tray when using different laundry processing liquids and when using one laundry processing liquid.
