If the compressor is continuously operated in the stopped state, the temperature of the compressor rises, and the temperature of the refrigerant rises, and is laid on the outer casing of the refrigerator. The refrigerant piping has also risen excessively. In particular, in an environment where the outside air temperature is high, the outer casing of the refrigerator has a high temperature. In the case of such a refrigerator, in the case where the machine room fan is malfunctioning or locked, the technique of controlling as follows is known as disclosed in Japanese Patent Laid-Open Publication No. 2003-121-32 (Patent Document No.): In order to prevent the corruption of food in the θ box as a priority, the compressor required for cooling the original refrigerator in the refrigerator is switched to a low speed, and the operation is continued to avoid the overload conversion of the compressor. However, such a previous refrigerator In the case where there is a problem to be solved as follows, since the compressor is switched to the low speed operation when the machine room fan fails without considering the external milk temperature, even if the following conditions are caused, the refrigeration efficiency is deteriorated due to the low speed operation: the outside air temperature is relatively high. Therefore, even if the normal operation of the compressor is continued, the temperature of the refrigerant does not become excessively high. [Patent Document 1] Japanese Patent Laid-Open Publication No. 2003-121032 [Abstract] 139169.doc 201007107 [Problem to be solved by the invention] The month is completed by the problem of the prior art, and the purpose is to provide a kind of refrigerator, which is preventable when the mechanical room fan is abnormally stopped. Not only the temperature of the machine room or the (4) machine, but the condition of the refrigerator casing becomes excessively high. m [Technical means to solve the problem] This issue: One feature is a refrigerator, which is equipped with a compression in the machine room. The mechanical to fan cools the machinery in the mechanical chamber by air: it has a mechanical room fan; it has: an external temperature sensor, which measures the outside air temperature around the moon I; the fan abnormality monitoring mechanism, which is a system Measuring the abnormal stop of the mechanical chamber fan; the compressor control mechanism is configured as follows: the fan abnormality monitoring mechanism detects the abnormal stop of the mechanical chamber fan, and the external air measured by the external temperature sensor, the temperature ratio is When the specific value is higher, control is performed to stop the compressor; and the fan abnormality display means displays an abnormality of the machine room fan when the compressor control means stops the compressor. The other feature of the present invention is a refrigerator in which a machine is equipped with a variable frequency control compressor, and a mechanical room fan is provided to wind the machinery in the mechanical chamber to provide a machine room fan; It has: an external temperature sensor' which measures the outside air temperature around the refrigerator; a fan abnormality monitoring mechanism, which is (4) the fan of the machine room is stopped; the compressor control mechanism is detected by the abnormality monitoring mechanism When the fan of the machine room is stopped normally, the temperature of the temperature sensor is more than the first special value, and the compressor is controlled to be faster than the normal speed. 139169.doc 201007107 = low speed deceleration operation; and fan abnormality display mechanism, which is caused by the compressor control mechanism to make the compressor decelerate the abnormality of the operation room fan. The other features of the invention are - a refrigerator, which is installed in a machine room and equipped with a machine that operates at a constant speed, and is provided with a mechanical room fan in a machinery room in which the machine room is cooled by a wind core, and has a machine temperature fan; The outside air temperature around the aforementioned refrigerator; the fan abnormality: the abnormal mechanism of the machine mechanism is detected by the mechanism; the compressor control mechanism is the fan abnormality monitoring mechanism _ to the aforementioned machine : Fan: often stops for one time, and when the outside air temperature measured by the external air overflow sensor is higher than a specific value, the compressor is controlled to be intermittently operated in a predetermined cycle; and the fan abnormality display mechanism 'When the compressor control mechanism intermittently operates the compressor, the abnormality of the machine room fan is displayed. [Embodiment] [Effect of the Invention] According to the refrigerator of the present invention, when the machine room fan is abnormally stopped, if the outside air temperature is higher than a specific value, the abnormality of the machine room fan is displayed externally, and the compressor is stopped. It is a low-speed operation or an intermittent operation. Therefore, even if the machine is stopped, the room fan will stop 'the temperature of the machine room will not rise due to the heat generated by the compressor.' As a result, the refrigerant can be prevented from becoming high temperature, and the surface of the refrigerator can be prevented from circulating due to the outer casing of the refrigerator. The refrigerant in the refrigerant piping excessively becomes a high temperature. Hereinafter, embodiments of the present invention will be described in detail based on the drawings. [First Embodiment] 139169.doc 201007107 As shown in Fig. 1, the main system of the refrigerator 1 is formed by the heat insulating box 2, and the internal storage chamber is divided into the refrigerator compartment 4 and the freezing compartment 6. A refrigerating evaporator (hereinafter referred to as "R evaporator") 7 and a cooling fan (hereinafter referred to as rR fan) 8 are disposed on the back surface of the refrigerating compartment 4, and a refrigerating evaporator is disposed on the back surface of the freezing compartment 6. (hereinafter, referred to as "ρ·evaporator".) 14 and a cooling fan (hereinafter referred to as "ρ fan"). A machine room is formed in the back to form a space in the cold image to the lower side, and a compressor 11, a machine room fan 2, a three-way valve 15, and the like are provided in the machine room 10. As shown in Fig. 2, the refrigeration cycle sequentially connects the compressor that discharges the refrigerant to the condenser 12, and in the subsequent stage, the two pipes are connected in parallel, and are connected to each other on the suction side of the compressor 11, and the two pipes are connected. The three-way valve 15 is connected in series to the capillary for freezing "and the evaporator 14"; and the capillary for refrigeration is connected! 7 with R evaporator 7. Further, a check valve 18 is connected between the outlet of the F evaporator 14 and the suction side of the compressor 11. The three-way valve i 5 system can switch the flow of the refrigerant to the R evaporator 7 side and the F evaporator side 4 to four modes: open to the R evaporator (10) evaporator 14 both sides of the flow path of the full opening open R evaporation On the side of the unit 7, the F evaporator side is closed, the R flow is closed, the F evaporator side is opened only, the R evaporator top is closed, and the flow path of both sides is closed. In this cooling ring, the following refrigerant circulation is performed: when the refrigerator is started, the temperature in the refrigerator compartment 4 and the cold chilling compartment 6 is higher than a specific temperature: the shape is set to fully open the three-way valve 15 to make the slave compressor The cold sprayed from η, from the condensation 1512 to the three-way valve 15', is split into the capillary tubes 16, 17, which are respectively evaporated on both sides of the R evaporator evaporator 14, and are again sucked back from the accumulator through the 139169.doc 201007107 suction tube. Machine 11. The cold air generated by both the R evaporator 7 and the F evaporator 14 is sprayed into the respective chambers by the R fan 8 and the F fan 13, and the stored product is cooled. When the freezing chamber 6 has been cooled to the set temperature by the above cooling action, and the temperature of the refrigerating chamber 4 has not been lowered to the set temperature, the three-way valve i 5 is switched to become the R flow, and the refrigerant is only from the three-way valve 15 It is introduced to the side of the R evaporator 7. The cold air is introduced into the refrigerating compartment 4 by the operation of the R fan 8, and is cooled. ❹ When only the freezer compartment 6 is at a set temperature or higher, the three-way valve 15 is f-flowed, and the refrigerant discharged from the compressor 11 is evaporated from the condenser 12 and the capillary 16 in the F evaporator 14 and returned via the accumulator. The compressor 丨丨, the cold air generated in the F evaporator 14 is supplied to the cold by the ρ fan π; the east chamber 6 is cooled. When the refrigerating compartment 4 and the freezing compartment 6 have been cooled to a specific temperature, respectively, the control is performed in such a manner that the temperature sensor 0 disposed at an appropriate portion in the tank detects the switch and switches the three-way valve 15 to perform cooling. Alternatively, the operation of the compressor 11 and the cooling fans 8, 13 is stopped, and the control unit 21 is controlled by the control unit 21. The configuration of the machine room 10 will be described with reference to Fig. 3 . In the machine room, a plurality of cold cycle parts and piping such as a connecting pipe to the compressor U or the condenser 12 disposed on the bottom surface of the main body, the three-way valve 15, the capillary tubes 16, 17, and the heat pipe 25 are disposed. . In addition, a mechanical room fan (hereinafter referred to as "C fan") 20' is provided in the machine room 1 and is used to take outside air into the inside of the machine room 1'. The heat generating member such as the tube 25 is cooled by the wind 139169.doc 201007107. This C fan 20 is also controlled by the control unit 21. In order to obtain a wide heat dissipation area, the heat pipe 25 is piped as follows: from the condenser 12, after passing through the sky face or the back surface of the casing of the refrigerator 1 (not shown), the machine is returned to the machine room 1 Three-way valve 15. For example, in the case where the refrigerator 1 is placed in a high-temperature gas environment or in a high-temperature gas environment in summer, and the heat-dissipation conditions are poor, such as the failure of the C-fan 20, the compressor 11 cannot be cooled, and the high-temperature state is maintained. 'There is a phenomenon that the temperature in the machine room 10 is excessively high and the temperature of the outer casing of the refrigerator 1 is excessively high. Fig. 4 is a block diagram showing the control function of the control device 21 in the refrigerator of the present embodiment. Fig. 5 is a flow chart showing the control function of controlling the compressor 11 to prevent the outer casing of the refrigerator 1 from becoming excessively high when the C fan 20 is abnormally stopped. It is assumed that the outside air temperature sensor 22' for measuring the outside air temperature is provided in an appropriate place of the refrigerator 1 (for example, the back surface of the machine room, the ceiling surface or the side surface), and the outside air temperature measurement value is input to the control device 21. Further, it is assumed that an operation panel for temperature adjustment and a display 23 are provided at appropriate places in the door of the refrigerating compartment 4 to display display information output from the control device 21. Further, the control device 21 inputs an operation signal of the power switch 24 of the refrigerator 1, controls the start/stop of the compressor n, controls the start/stop of the fan 20 of the machine room 1 , and monitors the c fan 2〇. The motion detection stops abnormally. The control operation of the compressor η when the C fan 20 of the control device 21 is abnormally stopped is as follows. 139169.doc 201007107 The control device 21 starts the compressor with the power source turned on, starts the c fan 2〇, and monitors the operation of the C fan 20 (steps si, S2). Then, if the abnormality has not occurred in the c-fan 20, the normal operation is continued (NO in step S3). When the C fan 20 is abnormally stopped, the control device 21 restarts the restart of the c-fan 2 to a predetermined number of times N (for example, three times) (steps S3 to S5). The time interval of this repetition is preferably set to be one time, one time, and one hour. Then, if the C fan 20 is actually restarted after the restart control until N times, it is determined that the c fan 2 is not malfunctioning and returns to the normal operation (in step 35, it is NO, and in the step "bifurcation" No. However, if the C-fan 20 does not restart the N-time restart attempt, then it is determined whether the temperature outside the temperature sensor 22 is determined by the bit value Trefl (-31 C ), Tref2 (=33 ° C ) is high (in step S5, it is YES to proceed to step S6). This temperature condition is merely an example, and is not limited thereto. In the above, the specific value has Tref1, Tref2. The two φ systems are used in order to use Tref2 when the outside temperature rises.

This point is also the same in the description of the following embodiments. In this step 6, if the outside air temperature is higher than the specific value Tref2 and the compressor is continuously operated, the inside of the machine room 10 becomes high temperature and the outer casing of the refrigerator is excessively high temperature, and in order to prevent it, the compressor u is The operation is stopped (steps S6, S7). Then, 'the display 23 is caused to display the abnormality of the c-fan 2G (step S8). On the other hand, the C-fan 20 is abnormally stopped, even if the restart attempt of the 139169.doc 201007107 is not restarted, such as If the outside air temperature is lower than w2, the compressor will continue to operate (the operation of the compressor will continue to cool the food in the box (steps %, S9). However, in this case, since an abnormality has no doubt occurred, the display 23 is caused to display an abnormality of the c fan 2 (step sl). In addition, even if the outside temperature is high, the temperature of the compressor is stopped, and if the outside temperature is lower than (10), the compressor 11 is restarted and the cooling operation is started again. . When the abnormality of the C fan 20 of the display 23 is seen, the user _ degrees will be switched back on after the power is turned on. If the operation is normally broken, the user's power is regarded as being put into operation again, and the refrigerator is taken into operation. The operation is restarted (the forks are not in steps S11, S12). In order to recover abnormally, no matter how many times the user restarts the operation of the refrigerator, if the abnormality of the C fan 20 is not restored, the manufacturer must be repaired. Therefore, if the repair technician performs the inspection and repair of the refrigerator 1, it is judged as a technician by the special operation of the power switch 24 which has been set in advance, and is transferred to the inspection and repair mode (steps su, SU, S13). ). In this way, according to the type of the refrigerator of the present invention, the degree of abnormality stops, and the control device 21 judges whether the C-fan 20 is actually malfunctioning by restarting by two Z, because, for example, after N times. If the restart of the C-fan 20 can be performed within the start-up attempt, the normal operation is continued. Therefore, the abnormality of the c-fan 20 can be surely determined.

The refrigerator in this embodiment! The structure is the same as that of the first embodiment, as shown in Figs. Therefore, in the following description, elements common to the first embodiment are denoted by common symbols. The present embodiment is characterized in that the control of the compressor ji during the abnormal stop of the fan 2 is performed by the control device 21, and the control device 2 is controlled as follows. When the C fan 2 is abnormally stopped, & reducer ^ set to low-speed rotation to make the operation of the cold-comfort cycle as continuous as possible, such as the N-time restart attempt and the C-fan 20 does not restart, then it is regarded as an abnormal fault according to 139169.doc 201007107 The temperature of the compressor 11 is stopped, and the operation of the refrigeration cycle is ended. The functional configuration of the control device 21 is the same as that of the i-th embodiment, as shown in Fig. 4. Then, the control flow of the control device 21 is as shown in FIG. 6. Further, in the following aspects, the control system in which the compressor n is rotated at a low speed and continues to operate means that if the compressor is controlled by the inverter, the frequency is reduced to a preset minimum frequency for operation. On the other hand, if the compressor 11 is operated at a certain speed, it means that in the following description, instead of the control for reducing the low-speed rotation, the switching is performed so that the rotation of the compressor 丨j is intermittently operated at a predetermined cycle. control. The control device 21 turns on the compressor u by the power source, activates the c fan 2, and monitors the operation of the C fan 20 (steps S1, S2). Then, if the c fan 2 does not cause an abnormality, the normal operation is continued (the fork is not at step S3). When the C fan 2G is abnormally stopped, the control device 21 continues the operation until the compressor (1) has reduced the number of revolutions to the threshold (steps Μ, S4A). Then, the restart of the C fan 2 is repeated until the preset number n is reached (steps S4B to S5). Repeat (four), repeat the time interval and the first! The implementation type is the same as #. Then, if the restart of the fan 2 is actually restarted, the CPU 2 determines that the C fan 20 is not malfunctioning, and returns to the normal operation (NO in step S5, and again in step S3). no). However, if the C-fan 2 实际 does not restart the N-time restart attempt, it is determined whether the temperature outside the air temperature sensor 22 is a bit, and the values Tref1 (=3lt) and Tref2 are High (in step 2, it is again 1 to step S6). This temperature condition is the same as the third implementation type 139169.doc 201007107. Then, in the aspect after step S6, the same control as in the first embodiment is performed. In this way, according to the refrigerator of the second embodiment, the same effects and effects as those of the first embodiment can be exhibited. In addition, according to the second embodiment, when the abnormality of the C-fan 20 is stopped, the compressor 11 is once switched to a specific low-speed operation 'while continuing the operation of the cold wire loop' and Since the fan 20 is repeatedly tried again and again, there is an advantage that the temperature inside the tank can be suppressed during the period of the restart attempt, and damage of the food in the box can be avoided as much as possible. * In the second embodiment, the external temperature sensor 22 stops the compressor u when the outside air temperature is high. However, the present invention is not limited thereto, and the C fan 20 is detected. When the abnormal stop is performed and the restart is attempted N times and the c fan is not restarted, the control for stopping the compressor 11 without considering the outside air temperature may be employed. [Third embodiment] A refrigerator according to a third embodiment of the present invention will be described with reference to Figs. 4 and 7 . The structure of the refrigerator in this embodiment is the same as that of the first embodiment, as shown in Figs. 1 to 3 . Therefore, in the following description, elements common to the first embodiment are denoted by common symbols. The present embodiment is also characterized in that the control unit 21 performs control of the compressor 时 when the control unit 21 performs abnormal stop of the fan 20, and the control unit 21 performs control. When the C fan 20 is abnormally stopped, an attempt is made to N. The second restart, even if the C fan 20 does not restart, it is regarded as an abnormal fault, 139l69.doc -13- 201007107 The money machine u is stopped according to the outside air temperature, and if the outside temperature is lowered thereafter, Then, the cold machine is restarted to make the cold; the operation of the east cycle is intermittent in the possible range. b The functional configuration of the control device 21 is the same as that of the #th embodiment, as shown in Fig. *. Then, the control flow of the control device 21 is as shown in FIG. The control device 21 turns on the compressor u by the power source, activates the c fan 2, and monitors the operation of the C fan 20 (steps S1, S2). Thereafter, the processing of steps si and s1 is the same as the processing of the third embodiment shown in Fig. 5. When the phase C fan 2 is abnormally stopped, the compressor η is stopped according to the temperature of the outside air temperature, or the performance is maintained. After the display 23 displays the abnormality of the c fan 2: the control device continuously monitors the outside air temperature. Then, after the compressor 11 is stopped, if the temperature is less than Tref1 as measured by the outside air temperature sensor 22, the elapsed time from the stop of the compressor u is observed, and it is determined whether or not the time has elapsed; t time (step S21, S22). Then, if the outside air temperature becomes below Tref1 and has passed the specific time from the stop of the compressor, the compressor is restarted (step S23) e is restarted here, since the abnormality of the c fan 20 has not been eliminated. @This continues to cause the display m to display the point of abnormality of the c fan 2 (step S24). The control processing after the compressor 11 is restarted is the same as the processing after step S11 in the fifth embodiment shown in FIG. 5, and when the abnormal notification of the C fan 20 of the display 23 is seen, the user once switches the power supply. In the case of being turned back on again, if the operation is normally turned on and off, it is regarded that the power of the user is put back into operation, and the operation of the refrigerator 1 is restarted (NO in steps S11 and S12). . 139169.doc 201007107 For abnormal recovery, no matter how many times the user operates the refrigerator! If the abnormality of the C fan 20 is not restored, the manufacturer must be repaired. Therefore, if the repair technician performs the inspection and repair of the ice (1), it is judged to be a technician by the special operation of the power switch 24 which has been set in advance, and 1 is transferred to the inspection/repair mode (step_b 812, S13).

In addition, according to the third embodiment, the 'C fan 20 is abnormally stopped, even if the outside air temperature is high, the compression is stopped, and then the outer temperature is lowered to (10), and (4) the stop of the compressor 11 is stopped. If the specific time has elapsed, the compressor will be restarted and the cooling in the tank will be started again. In this way, it is possible to prevent the outer shell of the ice from becoming excessively high due to the high outside air temperature and the stop of the compressed oil. And try to avoid damage to the food inside the box. Further, in the present embodiment, it is assumed that the abnormal restart of the C fan 20 is confirmed by the N restart attempt. However, this technique is employed as needed, and for the simplification of control, 〖Second stop detection and judged to be abnormal stop. [Fourth embodiment] A refrigerator according to a fourth embodiment of the present invention will be described with reference to Figs. 4 and 8 .

This embodiment is also characterized by a compressor that is abnormally stopped by the fan 139169.doc 201007107 by the control device 21! ! The control, control device 2 ^ is controlled as follows: when the C fan 20 is abnormally stopped, the compression is set to a low speed rotation to be cold; the operation of the east cycle is as continuous as possible, such as the restart of the C drive 20 If it is not restarted, it will be regarded as an abnormal failure. The compressor 11 will be stopped according to the outside air temperature, and will be cold. The operation of the east cycle will end, but as in the third embodiment, it will be monitored later. If the temperature has decreased and the specific temperature has elapsed since the stop of the compressor ii, the compressor 11 is restarted and the cooling in the tank is started again. The functional configuration of the control device 21 is the same as that of the i-th embodiment, as shown in the figure. Then, the control flow of the control device 21 is as shown in FIG. Further, in the squatting aspect, the control system in which the compressor Η is set to rotate at a low speed and continues to operate means that if the compressor 11 is controlled by the inverter, the frequency is reduced to a preset minimum frequency for operation. On the other hand, the case where the compressor is operated at the 疋 speed means that, in the following description, 'the control for reducing to the low speed rotation is replaced, and the rotation of the compressor is switched to the intermittent operation at a predetermined cycle. control. The control device 21 turns on the compressor η by the power source, starts the c fan ❹ 2〇, and monitors the operation of the C fan 20 (steps S1, S2). In this step, the processing of steps S3 to S10 and the processing of steps su to sn are common to the processing of the third embodiment of FIG. 3, and then the processing of steps S21 to S24 after step S8 is performed. The process of the third embodiment shown in Fig. 7 is common. In this way, the refrigerator 1 according to the fourth embodiment can exhibit the same functions and effects as those of the first embodiment. 4 implementation type, 139169.doc • 16 - 201007107 = 2 implementation type is also the same as 'the control device 21 is in the C fan 2.

The functional configuration of the control device 21 is the same as that of the first embodiment, as shown in Fig. 4 . Then, the control flow of the control device 21 is as shown in FIG. Further, in the following aspect, the control system that continuously rotates the compressor 11 at a low speed means that if the compressor 11 is controlled by the inverter, the frequency is reduced to a preset minimum frequency. On the other hand, the case where the compressor 11 is operated at a constant speed means that, in the following description, 'the control for reducing to the low-speed rotation is replaced, and the rotation of the compressor 丨i is switched to a predetermined period. Control of intermittent operation. The control device 21 activates the compressor to start the c-fan 20' and monitors the operation of the C-fan 20 (steps si, S2). Then, if no abnormality occurs in the C fan 20, the normal operation is continued (the fork is not at step S3). When the C fan 20 is abnormally stopped, the control device 21 restarts the c fan 2 to the predetermined number of times N (steps S4 and S5). The number of times of repetition N and the time interval of repetition are the same as those of the first embodiment. Then, if the fan 2 is actually restarted after the restart control until N times, it is determined that the C fan 20 is not malfunctioning, and returns to the normal operation (NO in step S5, and bifurcation in step S3) No). However, if the restart attempt of the C-fan 20 for N times is not actually restarted, then it is determined whether the temperature measured by the outside air temperature sensor 22 is lower than the reference value of the 139169.doc -18 - 201007107 i (10) (= 3 i. (: Yang Qingxun) is high (in step and then YES, proceed to step S6). This temperature condition is the same as the i-th implementation. Then 'because the temperature ratio is the reference value When D (10) / D is low, the air cooling of the machine room 1 is stopped by the abnormal stop of the C fan 20, and even if the compressor m is continuously operated, the machine room 1 does not excessively become a high temperature 'and The temperature of the outer casing of the refrigerator 1 is not excessively high, so that the normal operation of the continuous reduction machine 11 is performed, and the display unit 23 displays the difference of the c-fan 2, and informs the user (in step S6, it is again , proceed to step ® S9 , S10). In step S6, 'if the outside air temperature is higher than the i-th reference value ) ^ 丨 ^ ^ / Tref2 (= 33 ° C), and continue the normal operation of the compressor ,, Then, the machine room ίο内谷 is easy to become warm, so the control of steps S7A to S7C is performed. That is, since the compressor is not in the following environment, the compressor 丨丨 is maintained at the normal operation speed R1 (steps S7A, S7B) as in the past, and the environment is: even if the fan 20 is in an abnormal stop state, such as the outside temperature ratio 2 When the reference value φ Tref3/Tref4 is low, the inside of the machine room 10 becomes high temperature, and the temperature of the refrigerator casing is excessively high. "This situation is stopped by the C fan 2". In general, it is necessary to prevent the temperature from rising. The compressor 丨i is rotated at a high speed R2 (>R1), but it is set to maintain the operating speed of R1 to minimize damage to the food in the box. On the other hand, when the C-fan 20 is in an abnormally stopped state, if the outside air temperature is higher than the second reference value Tref3/Tref4, the temperature in the machine room 1 is high, and the temperature of the casing of the refrigerator 1 is excessively high. The compressor 11 is prevented from being continuously damaged by the damage of the food in the box, but the operation is resumed until the low speed R3 (<R1) is reduced (steps S7A, S7C). Then, in either of the cases, the indicator 23 is caused to display the abnormal stop of the c fan 20 (step S8). Thereafter, the processing after step S11 is the same as the third embodiment. In order to recover abnormally, no matter how many times the user restarts the operation of the refrigerator 1, if the abnormality of the C fan 20 is not restored, the manufacturer must Repair commission. Therefore, if the repair technician performs the inspection and repair of the refrigerator, it is judged as a technician by the special operation of the power switch 24 which has been set in advance, and is transferred to the inspection and repair mode (steps sil, si2, si3). ).藉 By this way, according to the fifth embodiment of the refrigerator, you can also play with the first! The same effect and effect of the implementation type. In addition, according to the fifth embodiment, the reference of the outside air temperature is divided into two stages, and in the high temperature environment where the outside air temperature exceeds "^", the compressor U is operated at a certain speed to suppress the box. If the internal temperature rises, if the outside air temperature becomes higher, the rotation speed of the compressor η is more concentrated. In this way, the operation of the minimum capacity of the cold bed cycle can be continued, and the refrigerator can be prevented from being double-shelled. The excessive temperature rise of the temperature and the operation of the food in the box is avoided as much as possible. Further, in the above, the rotation speed of the compressor 11 is controlled by two-stage temperature monitoring in two stages, but In more stages, it is also possible to make a continuous change in the rotational speed based on the outside air temperature. Also, in the case where the compressor U is operated at a constant speed, for example, the operation is performed in one cycle during intermittent operation. The ratio of the time may be changed. [Sixth embodiment] 139169.doc -20- 201007107 A refrigerator according to a sixth embodiment of the present invention will be described with reference to Figs. 10 and 11. The refrigerator in this embodiment mode. 1 structure and The first embodiment is the same as that shown in Fig. 1 to Fig. 3. Therefore, in the following description, elements common to the first embodiment are denoted by common symbols. The feature is as follows: as shown in FIG. 10, a machine room temperature sensor 26 for measuring the temperature in the room is provided in the machine to 1 ,, and when the fan 2 is abnormally stopped by the control device 21 The control of the compressor 11 is performed with reference to the measured temperature of the outside air temperature sensor 22 and with reference to the measured temperature of the machine room temperature sensor 26. That is, the control device 21 is controlled as follows: When the fan 2 is abnormally stopped, if the compressor is restarted for 1HtN and the fan 2 is not restarted, it is regarded as an abnormal failure, and the outside air temperature is high and the temperature of the machine room is also high. The compressor rotation speed is switched to a low speed or stopped, and the machine room temperature sensor 26 is preferably disposed in the vicinity of the compressor or heat pipe 25 of the heat generating component in the machine room. The functional structure of the device 21 As shown in Fig. 10. Then, the control flow of the control device 21 is as shown in Fig. u. The control device 21 turns on the compressor 11 by the power source, starts the C fan 20, and monitors the action of the c fan 2 (step S1). Then, if there is no abnormality in the c fan 2, the normal operation is continued (NO in step S3). If the C fan 20 is abnormally stopped, the control device 21 causes the c fan to start repeatedly. Until the preset number of times N (steps S4, s5, the number of times of repetition N, and the time interval of repetition are the same as those of the third embodiment. Then, the restart of the fan is performed by the restart control until N times. 139169.doc 201007107 The tongue is #j broken as the c-fan 20 is not a malfunction, and the ❿ is restored to the normal operation (in the step to divide it or not 'in step S3, it is no). However, if the C fan 2 (4f after the restart attempt of the ^fN times does not actually restart), it is determined whether the temperature outside the air temperature sensor 22 is determined to be bit ^Trefl(=3rC)/Tref2(=33° C) ^ high (in step S5, YES, then proceeds to step S6). This temperature condition is the same as the i-th embodiment. Then, since the temperature is higher than a specific value, the temperature is necessarily lower. By the c fan 20; ji stop and stop the air cooling of the machine room iq, and even if the machine 11 continues to operate 'the machine room 1〇 does not become high temperature' and the refrigerator i's shell is not excessive When the temperature is high, the normal operation of the compressor U is continued, and the indicator 23 displays the abnormal stop of the C fan 20, and informs the user (if the fork is not completed in step S6, the process proceeds to step S9, si). In step S6, if the outside air temperature is higher than the specific value Trefl/Tref2, and then refer to the machine room temperature, if the machine room temperature has become excessively high temperature, the compressor 11 is stopped. By this way, the machine room ig is prevented. Becomes a high temperature, and the temperature of the outer casing of the refrigerator i becomes excessively high (step %, s3i, S32) Then, the display unit 23 displays the abnormal stop of the c fan 2〇 and informs the user (step S8). Thereafter, the processing after step S11 is the same as the β-th construction mode, and the user will How many times to restart the operation of the refrigerator, if the abnormality of the fan 20 is not restored, the manufacturer must be repaired. Therefore, the repair technician should carry out the inspection and repair of the refrigerator, which is pre-set by the technician. The special operation of the power switch 24 is judged to be a technician, and is transferred to the inspection/repair mode (steps S11, Si2, and S13). 139169.doc *22- 201007107 In this way, the refrigerator according to the sixth embodiment is In addition, according to the sixth embodiment, the machine room temperature sensor 26 for measuring the temperature in the room is provided in the machine room 10 according to the sixth embodiment. When the temperature of the compressor 11 is abnormally stopped by the control device 21, the temperature of the external temperature sensor 22 is referenced and the temperature of the temperature measurement of the machine room temperature sensor 26 is referred to. Progress 'When the outside air temperature is still warm and the machine room temperature is also high, the rotation speed of the compressor 11 is stopped. By doing this control, as long as the case of the refrigerator's ® case is excessively temperature rise, the compression is performed. The machine 11 is stopped, and it is prevented from becoming excessively high in temperature. In the above description, the case where the control for stopping the compressor ii is stopped is described, but it may be replaced with a compressor. The control is continued at low speed and continues to operate. Then, in the case where the compressor is controlled by the inverter, it is set to operate at a low speed by reducing the frequency to a preset minimum frequency. On the other hand, the case where the compressor is operated at a constant speed, for example, replaces the control for reducing the rotation to the low speed, and controls the rotation of the compressor 11 to be intermittently operated at a predetermined cycle.
