(a) Industrial Application Field The present invention relates to a washing machine that uses a temperature sensor to perform appropriate washing according to water temperature. (b) Prior art A method that detects the temperature of washing water and controls the process time according to the temperature is disclosed in Japanese Patent Application Laid-open No. 55-66394. The washing effect changes greatly. When detecting water temperature,
The temperature sensor is attached to the tank, but since contact with water is unstable at the top of the tank, it is attached to the bottom of the tank. However, in the corners of the lower part of the tank, the water in the tank tends to stagnate, and lint and dirt tend to remain at the end of the washing process, reducing the detection ability. (c) Problems to be solved by the invention The present invention aims to improve and maintain the detection ability of the temperature sensor. (d) Means for solving the problem The solution according to the present invention is to form a recess in the inner bottom of the washing tub, and to form a drainage chamber communicating with the recess on the side of the recess, The opening of the drainage chamber to the washing tub is covered with a cover having a group of through holes, a rotor with a back blade is disposed in the recess, and a temperature sensor is placed inside the drainage chamber. The structure consists of: (E) Function Water quickly flows into the drainage chamber through the recess and the group of through holes, and its temperature is detected by a sensor. Also, during operation, the water in the tank is forcibly sent to the drainage chamber by the back blade of the rotor blade and circulated using the above-mentioned group of holes, and the sensor detects the water in the tank. temperature can be accurately detected. Also, during operation, lint and dirt are blown away by the back blade, making it less likely that they will stick to the sensor. Furthermore, when draining water after completion, lint and dirt around the room are quickly discharged, and lint and dirt from outside are caught by the through-holes of the cover and are prevented from entering the room. (f) Example To explain based on the drawings, in FIGS. 2 and 3, 1 is a two-tub washing machine in which a washing tub 3 and a dewatering tank 4 for centrifugal dehydration are arranged side by side in the machine frame 2. be. A vertical centrifugal dewatering tank (not shown) is disposed inside the dewatering tank 4, and a rotary blade 7 having radial back blades 6 is provided in the recess 5 at the inner bottom of the washing tub 3. It is arranged. Reference numeral 8 denotes an operation unit provided in the machine frame 2, which is a means for controlling operation and is equipped with a microcomputer (hereinafter referred to as the microcomputer) 10 that has a built-in counter 9; 10, a wash key 12 is used to determine the washing (including rinsing, the same applies hereinafter) time, and a dehydration key 13 is used to determine the dehydration time.
There are also provided a water flow key 14 for instructing the strength of the water flow during washing (changing the reversal period of the rotary blade (7)), and an operation start/stop key 15. The operation panel 11 also has a washing time display section 16, a dehydration time display section 17, and a water flow strength/weakness display section as display sections that turn on and off LED groups in accordance with character display groups according to instructions from the microcomputer 10. A display section 18 and a temperature display section 19 are provided. Furthermore, this operation panel 11
, there is a power switch knob 20, an operating lever 21 for adjusting the overflow water level, a drain button 22 for manually opening and closing a drain valve (not shown), and switching the water supply to the washing tub 3 and the spin-drying tub. A water injection button 23 is provided. Here, as shown in FIGS. 1 and 5, an overflow chamber 24 recessed toward the dehydration receiving tank 4 is integrally formed in one corner of the washing tub 3, and a recess 5 in the inner bottom is provided with an overflow chamber 24. The bottoms of the two are connected so that they are continuous. The bottom of the overflow chamber 24 has a drain port 25 that is opened and closed from above and below by the drain valve, a mounting hole 27 for a temperature sensor 26 consisting of a thermistor, etc., and a hole 27 between the mounting hole 27 and the recess 5. Upward boss located 2
8 is formed. And there are 2 mounting holes on the outer bottom.
A cylindrical portion 29 surrounding the overflow chamber 2 is installed vertically, and the temperature sensor 26 is inserted into the mounting hole 27 from below to connect the overflow chamber 2.
4, and the temperature sensor 2 is placed inside the cylindrical portion 29.
The seal portion 30 of No. 6 is fitted. Overflow room 2
The opening surface facing the tank No. 4 is covered by a pair of upper and lower covers 31 and 32 which are removable. The covers 31 and 32 form a large number of through holes 33, and the lower cover 32 is screwed to the boss 28. The drain valve disposed in the overflow chamber 24 also has an overflow pipe (not shown) operated by the operating lever 21, and this overflow pipe is connected to the overflow chamber 24.
The water in the chamber 24 is drained through the through holes 33, etc. according to the adjusted water level. In addition, 34 is a lower water injection channel, 35 is an upper water injection box,
36 is a dehydration tank, 37 is a drainage hose, and 38 is a lint filter. Here, to further explain the control circuit related to the microcomputer 10 based on FIG. 4, the microcomputer 10 includes:
The comparison result of the reference signal from the D/A converter 39 and the temperature signal from the temperature sensor 26 is inputted by the comparator 40, and a safety confirmation signal is sent from the safety switch 41 linked to the opening and closing of the dehydration tank 36. is input. The microcomputer 10 then operates, via the driver circuit 42, a buzzer 43, a motor circuit 44 that rotates the rotor blade 7 clockwise, a motor circuit 45 that rotates it counterclockwise, and a dehydration motor circuit 46 that rotates the dehydration tank at high speed. Next, the operation will be explained. First, when you turn on the power,
Corresponds to the standard characters on the water flow strength display section 18
The LED lights up, the temperature sensor 26 detects the temperature at the same time, and the temperature signal is stored in the microcomputer 10. Next, the laundry and, if necessary, detergent are added, the water level is determined by the operating lever 21, and water is supplied. The supplied water is city water or leftover hot water from baths. When the water flow is determined by the water flow key 14, the washing time is determined by the wash key 12, and the key 15 is operated, washing starts. During this water supply, the water quickly enters the overflow chamber 24 through the recess 5, through hole 33, etc., where the temperature sensor 26 immediately starts detecting the water temperature and inputs the temperature signal to the microcomputer 10. . Based on the temperature signal, the microcomputer 10 ranks the water temperature as C rank (warm) (24 degrees Celsius or higher) or B rank (normal) (12 degrees Celsius or higher).
The temperature is divided into three ranks: (lower than 24°C) and A rank (lower than 12°C), and the corresponding LED on the temperature display section 19 is lit. On the other hand, the microcomputer 10 lights up the corresponding LED in the water flow strength display section 18 and lights up all the LEDs shorter than the set time in the washing time display section 16. In the display units 16 and 17, the corresponding LEDs are turned off one after another as time passes.

[Table] In this way, the washing time set by the user is modified depending on the temperature of the water used, regardless of the washing time display, and the microcomputer 10 controls the operation according to the corrected time. go. The dehydration time is modified based on the temperature initially detected by the temperature sensor 26. In addition, "soft"
The time corresponding to the character display is 15 seconds. (G) Effects of the invention According to the invention, a temperature sensor is installed in the drainage chamber, and by sending water there with the back blade of the rotor, the sensor can constantly come into contact with the water in the tank. The water temperature inside the tank can be accurately detected. In addition, the back blade blows off lint, dirt, etc. to prevent them from adhering to the sensor, thereby maintaining the detection ability of the sensor.
Therefore, it is possible to provide a washing machine that can continue highly accurate operation control for a long time.
