Description

Technical Field

[0001] The present invention relates to the technology of environment sensing systems. Background Art

[0002] As a cooling and heating device for cooling or heating objects such as food, water, and clothing, there are refrigerators, heat pump water heaters, and washer-dryers. The device has the function of controlling the object to a specified temperature by supplying a specified power to a power source driving the device. When the device is working, it is accompanied by heat absorption and heat dissipation with the outside. Therefore, there is the following problem: if poor heat absorption and heat dissipation occurs due to device failure, installation in a narrow place, etc., the operating load increases, resulting in increased power consumption and a short life of the device.

[0003] In contrast, Patent Document 1 discloses a refrigerator (see abstract) which "detects poor heat dissipation when the difference between the temperature around the shell and the temperature of the refrigerant after condensation is lower than a specified value, and determines whether the cause of the poor heat dissipation is a cooling fan failure or a blockage in the ventilation path based on the rate of change of the temperature difference. According to the present invention, poor heat dissipation can be detected, and the cause of the poor heat dissipation can be determined and promptly dealt with."

[0004] Prior art literature

[0005] Patent Document 1: Japanese Patent Application Laid-Open No. 7-270020 Summary of the invention

[0006] Problems to be solved by the invention

[0007] According to the method described in Patent Document 1, poor heat dissipation caused by a failure or malfunction of the device can be detected based on the operating principle of the device and its cause can be identified, so that when poor heat dissipation occurs, it can be promptly dealt with.

[0008] On the other hand, the technology of Patent Document 1 is a so-called device sensing technology for detecting abnormalities of a device. Therefore, although the device has not failed, the heat dissipation conditions of the surrounding environment are poor, and therefore, the increase in operating load cannot be detected. For example, by placing the refrigerator in a place where heat is easily accumulated, when the temperature around the shell rises, in order to maintain the heat dissipation required for control, the operating load increases, but the refrigerator has not failed, so it is difficult to detect this situation by the judgment criteria of the prior art based on the action at the time of failure. In addition, it is difficult for the user to perceive during the normal operation of the device, so the state of load increase cannot be eliminated, and the possibility of poor heat dissipation becoming chronic is high.

[0009] The present invention is an environment sensing technology for solving such a problem, and aims to evaluate the heat dissipation conditions of the surrounding environment and to provide notification based on the evaluation results, thereby enabling the user to properly operate the device.

[0010] Means for solving problems

[0011] In order to solve the above-mentioned problems, the environment sensing system of the present invention is an environment sensing system of a heat and cold device having a driving source for generating heat and cold, a heat absorbing and dissipating unit to the outside, and an external temperature detecting unit, characterized by comprising: an evaluation unit that evaluates a heat absorbing and dissipating condition indicating whether the surrounding environment of the heat and cold device is suitable for heat absorbing and dissipating based on the amount of change in the detected temperature of the external temperature detecting unit during a predetermined evaluation period; and an output unit that notifies the evaluation result of the heat absorbing and dissipating condition evaluated by the evaluation unit. Other solutions are appropriately described in the embodiments.

[0012] Effects of the Invention

[0013] According to the present invention, the heat dissipation condition of the surrounding environment is evaluated and notification based on the evaluation result is made, thereby enabling the user to perform appropriate operation of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Next, a mode for carrying out the present invention (referred to as “embodiment”) will be described in detail with reference to the drawings as appropriate.

[0028] [First embodiment]

[0029] First, refer to Figure 1 to Figure 5 , a first embodiment of the present invention is described.

[0030] <Configuration of refrigerator environment sensing system Z>

[0031] Figure 1 1 is a diagram showing the structure of the environment sensing system Z of the refrigerator in the first embodiment. In the first embodiment, the environment sensing system Z of the refrigerator that evaluates the heat dissipation conditions of the surrounding environment of the refrigerator 100 and notifies the refrigerator 100 is shown. The environment sensing system Z of the refrigerator includes the refrigerator (heating and cooling device) 100, an evaluation unit 200, an output unit 201, and a storage unit 202.

[0032] (Refrigerator 100)

[0033] The inner space 101 of the refrigerator 100 and the outer space are separated by an insulating box body filled with an insulating material 102. The inner space 101 is divided into a plurality of chambers such as a refrigerator and a freezer, and each chamber is provided with a door 103 (doors 103a, 103b, 103c, 103d) that can be opened and closed. The refrigerator 100 has a compressor 110 (driving source), an evaporator 111 (heat absorbing part), a condenser 112 (heat dissipating part), and an expansion valve 113 (expansion device) constituting a refrigeration cycle. In addition, the refrigerator 100 has an air supply fan 104 (air supply fans 104a, 104b). In addition, the refrigerator 100 has an ambient temperature sensor 105.

[0034] The refrigeration cycle is formed by the refrigerant (heat transfer medium) circulating in the flow paths connected in a ring shape in the evaporator 111, the compressor 110, the condenser 112, and the expansion valve 113. The evaporator 111 is a heat exchanger that absorbs the heat of the space 101 in the box. The compressor 110 driven by the input energy compresses the gas-phase refrigerant evaporated in the evaporator 111. The condenser 112 uses cooling water or air to cool the gas-phase refrigerant compressed by the compressor 110, thereby dissipating the heat of the gas-phase refrigerant. At this time, the gas-phase refrigerant is liquefied to become a liquid refrigerant. The expansion valve 113 expands the liquid refrigerant coming out of the condenser 112 to become a low-pressure and low-temperature two-phase refrigerant, and sends it to the evaporator 111.

[0035] The blower fan 104 blows low-temperature air generated by heat exchange in the evaporator 111 into the interior space 101 (the temperature of the interior space 101 is controlled by the compressor 110 ).

[0036] In order to explain the control method of the refrigerator 100, Figure 1 The uppermost chamber separated from the space 101 inside the box is set as a refrigerator, and the middle chamber is set as a freezer. The refrigerator and freezer are cooled by the air generated by two air supply fans 104. When cooling the refrigerator, the air supply fan 104a is operated, and when cooling the freezer, the air supply fan 104b is operated, thereby supplying low-temperature air from the evaporator 111 to each chamber. The start and stop of cooling of each chamber are controlled according to the temperature inside the box. Specifically, cooling starts when the temperature inside the box becomes above a specified value, and stops when it becomes below a specified value. Thus, the temperature inside the box is maintained within a certain range.

[0037] In the refrigerator 100 that has been running for a long time, the moisture in the internal space 101 is condensed and solidified by the evaporator 111 to form frost, which adheres to the evaporator 111. If the adhesion of frost progresses, the performance of the evaporator 111 is reduced, so the defrosting operation is performed within the range of a prescribed time interval. During the defrosting operation, the compressor 110 is stopped, and the temperature of the evaporator 111 is increased by operating a heater (not shown) to melt the frost. And, when the temperature of the evaporator 111 becomes above a prescribed temperature, the compressor 110 is started to start cooling the internal space 101 again.

[0038] (Evaluation Unit 200)

[0039] The evaluation unit 200 is composed of a CPU (Central Processing Unit) and the like, and performs processing according to the evaluation method of the heat dissipation condition of the ambient environment described later. Therefore, the evaluation unit 200 is configured to obtain required information and signals from the ambient temperature sensor 105, the temperature sensor 120, and the compressor 110 via a signal line and the like. In addition, the evaluation unit 200 has a communication function, and the evaluation unit 200 sends the evaluation result to the output unit 201 and the storage unit 202.

[0040] (Output unit 201)

[0041] The output unit 201 (display device) displays the evaluation result of the evaluation unit 200, etc. The output unit 201 may be provided on the surface of the refrigerator 100, or may be a terminal (smartphone, PC, etc.) having a communication function used by the user.

[0042] (Storage Unit 202)

[0043] The storage unit 202 is composed of a HD (Hard Disk) and a RAM (Random Access Memory), and stores the evaluation result of the evaluation unit 200, the operation information of the refrigerator 100, and the like.

[0044] <Evaluation method of heat dissipation conditions in the surrounding environment>

[0045] Figure 2A as well as Figure 2B is a diagram showing an evaluation object and an evaluation period 305 in the evaluation unit 200. Figure 2A Corresponding to the case where the refrigerator 100 is installed in an environment with poor heat dissipation conditions, Figure 2B This corresponds to the case where the refrigerator 100 is installed in an environment with good heat dissipation conditions. Figure 1 and Figure 2A , Figure 2B The method of evaluating the surrounding environment is explained.

[0046] exist Figure 2A and Figure 2B In FIG. 1 , the horizontal axis represents time, the left vertical axis represents the actual ambient temperature 301 represented by a solid line and the ambient temperature sensor value 302 (the value of the ambient temperature sensor 105) represented by a dotted line, and the right vertical axis represents the operating load 303 of the compressor 110 represented by a dotted line. Figure 2A as well as Figure 2B The diagram shows the time changes of actual environment temperature 301 (room temperature of the room where refrigerator 100 is installed), ambient temperature sensor value 302, and operation load 303 of compressor 110. Operation load 303 of compressor 110 refers to the rotation speed of compressor 110, power consumption, and the like.

[0047] When the heat dissipation condition of the surrounding environment is poor, the exhaust gas whose temperature rises due to the heat dissipation from the condenser 112 is retained in the installation space. As a result, the ambient temperature sensor value 302 is higher than the actual ambient temperature 301, which is expressed as Figure 2A In contrast, when the heat dissipation condition of the surrounding environment is good, the exhaust gas does not stagnate in the installation space, and the ambient temperature sensor value 302 is about the same as the actual ambient temperature 301. Figure 2B As shown, the temperature deviation 304 becomes a smaller value.

[0048] In this way, the more difficult it is to dissipate heat in the surrounding environment of the refrigerator 100, the greater the temperature deviation 304 is. Therefore, by evaluating the temperature deviation 304, the heat dissipation condition of the surrounding environment can be estimated.

[0049] There are two specific methods for evaluating the temperature deviation 304 .

[0050] The first method for evaluating the temperature deviation 304 is described. Figure 1 ), the temperature detected by the temperature sensor 120 is the actual ambient temperature 301, and therefore the temperature deviation 304 is calculated based on the difference between the detected temperatures of the temperature sensor 120 and the ambient temperature sensor 105.

[0051] The second method for evaluating the temperature deviation 304 is described. Figure 1 ), the temperature deviation 304 is estimated only based on the ambient temperature sensor value 302. The specific method is as follows. First, when the compressor 110 is temporarily stopped during defrosting operation, etc., the heat dissipation from the condenser 112 stops. As a result, the temperature around the shell approaches the actual ambient temperature 301, and therefore, the ambient temperature sensor value 302 decreases. The change amount 306 at this time is proportional to the temperature deviation 304, and therefore, by obtaining the change amount 306, the temperature deviation 304 can be indirectly evaluated. The evaluation period 305 of the change amount 306 in the refrigerator 100 is during the defrosting in which the compressor 110 (driving source) is temporarily stopped, and the change amount 306 is the difference between the ambient temperature sensor value 302 at the beginning and the end of the defrosting. In addition, the evaluation period 305 is equivalent to the stop period of the driving source. In addition, the evaluation period 305 may also include a specified operation period after the stop. That is, the evaluation period 305 may also be the stop period and the start period of the driving source.

[0052] Figure 3 1 is a flowchart showing the process performed by the evaluation unit 200 in the first embodiment. Figure 1 and Figure 2A and Figure 2B .

[0053] exist Figure 3 In FIG. 1 , the actual environment temperature 301 is recorded as TR, the ambient temperature sensor value 302 is recorded as TS, and the difference between the actual environment temperature 301 and the ambient temperature sensor value 302, that is, the temperature deviation, is recorded as ΔT (=TR-TS).

[0054] First, the evaluation unit 200 obtains operation information of the refrigerator 100 ( S101 ). The operation information includes information on the operation load 303 of the compressor 110 , such as the rotation speed and power consumption of the compressor 110 , and information on the ambient temperature sensor 105 .

[0055] Next, the evaluation unit 200 checks whether there is another temperature sensor 120 (S110). If there is another temperature sensor 120 (S110, No), the actual ambient temperature 301 as the detected temperature is obtained (S121), and the temperature deviation 304 is calculated (S122). On the other hand, if there is no temperature sensor 120 (S110, Yes), the change amount 306 is calculated (S120).

[0056] Then, after S120 (when there are no other temperature sensors 120), the evaluation unit 200 evaluates the heat dissipation conditions of the surrounding environment by using the threshold judgment of the change amount 306. When the change amount 306 is above the threshold value that serves as a benchmark, the heat dissipation condition is judged to be "poor", and when it is less than the threshold value, it is judged to be "good" (S130a), and enters S131.

[0057] After S122 (when there are other temperature sensors 120), the evaluation unit 200 evaluates the heat dissipation conditions of the surrounding environment by using the threshold judgment of the temperature deviation 304. When the temperature deviation 304 is above the threshold value serving as a reference, the heat dissipation condition is judged to be "poor", and when it is less than the threshold value, it is judged to be "good" (S130b), and the process proceeds to S131.

[0058] Next, in S131, the evaluation unit 200 sends the evaluation result to the output unit 201. The evaluation result is not limited to the result of the threshold determination, but also includes the value of the temperature deviation 304 or the change amount 306, etc.

[0059] <Display screen 400>

[0060] Figure 4 2 is a diagram showing an example of a display screen 400 displayed on the output unit 201. In this example, it is assumed that the output unit 201 is a smartphone or a tablet held by a user.

[0061] In addition, Figure 4 The example shown shows an example in which the heat dissipation condition is relatively poor.

[0062] The display screen 400 displays the evaluation result of the current heat dissipation condition by the evaluation unit 200. The evaluation result display unit 410 displays the result of the threshold determination by the evaluation unit 200.

[0063] In addition, a rating result display unit 411 may be provided separately from the evaluation result display unit 410 to visually and easily understandably display the quality of the heat dissipation conditions evaluated in more detailed stages than the evaluation result display unit 410 by using rating bars or star ratings. Figure 4 In the example of FIG. 1 , the inverted triangle graph indicates the current state of the heat dissipation condition, which means that the further to the left of the bar the worse the heat dissipation condition, and the further to the right of the bar the better the heat dissipation condition.

[0064] In the detailed display unit 420, the basis for the evaluation results of the heat dissipation conditions displayed by the evaluation result display unit 410 and the scoring result display unit 411 are recorded. For example, the actual environment temperature 301 used for evaluation and the ambient temperature of the refrigerator 100 are also displayed. In addition, for users whose heat dissipation conditions are evaluated as "poor", the inferred reasons and the advantages of the solution are recorded. For example, as a cause, it is considered that the refrigerator 100 is installed in a narrow place, and more furniture is arranged near the refrigerator 100. In addition, as the advantages of the solution, the reduction in power consumption and the extension of the product life can be cited. In addition, for users whose heat dissipation conditions are evaluated as "good", the content of the method of use that encourages the continuation of the current situation can also be displayed.

[0065] The suggestion content display unit 430 displays a method for improving the heat dissipation conditions or a method of use suitable for the current heat dissipation conditions. For example, as a method for improving the heat dissipation conditions, it is notified whether there are obstacles such as corrugated paper placed in the form of blocking the top surface or exhaust port of the refrigerator, and a suggestion to move the movable object is displayed if there is a movable object, and a suggestion to use a shelf or the like to ensure the required space is displayed if the object is not movable. As a method of use suitable for the current heat dissipation conditions, a suggestion to reduce the level of the temperature adjustment setting is displayed. Here, if there are multiple proposal contents, they can be written in separate paragraphs, and each proposal content can be distinguished by numbers, letters, etc.

[0066] Furthermore, an input unit 205 may be provided in the display screen 400, and the user may input proposal contents that can be implemented or proposal contents that cannot be implemented. In this case, if there are multiple proposal contents, the corresponding numbers and letters are displayed on the input unit 205. The input information may also be stored in the storage unit 202, and the proposal contents may be customized according to the user by referring to the proposals made next time and after, and excluding the proposal contents that have not been implemented continuously. By the way, in Figure 4In the example, in the proposal content display section 430, as "usage suggestions", multiple pieces of proposal content (improvement countermeasures) such as "1. On the top surface of the refrigerator...", "2. At the exhaust port of the refrigerator...", and "3 (improvement countermeasure 3)" are displayed. The user can input, via the input section 205, the number of the usage suggestion that can be implemented, that is, the proposal content (improvement countermeasure).

[0067] In addition, the timing for displaying the evaluation result of the above heat dissipation conditions on the display screen 400 can be a pre-specified date and time, or there can be an input section 205 capable of setting the presence / absence of output of the evaluation result and the timing, and it is the timing indicated by the user through the input section 205.

[0068] Figure 5 It is a diagram showing an example of the display screen 400 displayed on the output section 201 when the heat dissipation conditions change significantly from the previous evaluation due to the user's actions, etc. In addition, in Figure 5 the example shown, an example where the heat dissipation conditions change from a relatively poor state to a good state is shown.

[0069] The display screen 400 has an evaluation result display section 410 and a scoring result display section 411. In addition, it has a history display section 440, and the evaluation results of the latest and past heat dissipation conditions are displayed in the history display section 440. For example, a graph with the horizontal axis representing the date and the vertical axis representing the evaluation result is displayed, and a reference line 441, plot points 442, and an evaluation result change amount 443 are displayed in the graph. In addition, the reference line 441 represents the threshold for determining the heat dissipation conditions as "poor". In addition, the plot points 442 correspond to each evaluation result. And it has a detailed display section 420 that displays the effect of improving the heat dissipation conditions. For example, the estimated value of the reduction ratio of annual power consumption is displayed, etc.

[0070] That is, the evaluation unit 200 can compare the evaluation result of the heat absorption and dissipation conditions at the previous evaluation stored in the storage unit 202 with the current evaluation result, and output the improvement degree of the heat absorption and dissipation conditions to the output unit 201.

[0071] In addition, the environmental sensing system has: an input section 205 (refer to Figure 4 ); and a storage unit 202 that stores the output content output to the output unit 201 and the user input information corresponding to the input content input from the input section 205. The evaluation unit 200 can correct the output content based on the output content and user input information stored in the storage unit 202 up to the previous evaluation, and output it to the output unit 201.

[0072] According to the first embodiment, although the refrigerator 100 has not failed, the operating load 303 of the compressor 110 can be detected to have increased due to the poor heat dissipation conditions of the surrounding environment. For example, when the refrigerator 100 is in an environment where heat dissipation is easy without walls or furniture around it, the surrounding temperature is approximately the same as the actual ambient temperature 301, so the temperature deviation 304 is approximately 0 degrees. On the other hand, when the refrigerator 100 is in a place where heat dissipation is difficult due to the proximity of surrounding walls, the temperature deviation 304 increases. Therefore, the evaluation unit 200 can evaluate the heat dissipation conditions by performing a threshold determination using the temperature deviation 304.

[0073] According to the first embodiment, the actual environment temperature 301 can be acquired by installing another temperature sensor 120 at a distance from the refrigerator 100. Thus, the temperature deviation 304 can be directly calculated, and therefore the heat dissipation condition can be evaluated with high accuracy.

[0074] Furthermore, according to the first embodiment, the change amount 306 can be calculated based on the operating load 303 and the ambient temperature of the compressor 110. In addition, the change amount 306 is proportional to the temperature deviation 304, so the heat dissipation condition can be evaluated using the change amount 306 instead of the temperature deviation 304. That is, the heat dissipation condition can be evaluated based only on the operating information.

[0075] Furthermore, according to the first embodiment, the user can understand the heat dissipation conditions of the surrounding environment of the refrigerator 100 in use, and know the improvement method and the appropriate use method. Specifically, the user can easily understand whether the current heat dissipation condition is "good" or "bad" from the evaluation result display unit 410 of the display screen 400. In addition, the user can intuitively understand the quality of the heat dissipation condition from the scoring result display unit 411 in a more detailed stage than the evaluation result display unit 410.

[0076] Furthermore, the user can confirm the basis of the evaluation result of the heat dissipation condition from the “Detailed Report” of the detail display unit 420 , and if the heat dissipation condition is “bad”, the user can understand the reason for the estimation and the advantages that can be obtained when the heat dissipation condition is improved.

[0077] In addition, the user can learn about the improvement methods of the heat dissipation conditions and the usage methods that match the heat dissipation conditions (the usage methods suitable for heat dissipation conditions) according to the "Usage Suggestions (Improvement Measures)" of the proposal content display unit 430, so that the user can choose and practice the proposal content that can be easily dealt with.

[0078] This can provide users with a reasonable evaluation result of heat dissipation conditions and appropriate usage methods, which can encourage users to change their behavior. Furthermore, by responding to the notification, users can use the device more appropriately, which can reduce electricity bills and extend the life of the device.

[0079] Furthermore, according to the first embodiment, since the proposed contents implemented by the user and the proposed contents not implemented by the user are stored, it is possible to make a proposal that matches the user each time the number of proposals is increased.

[0080] Furthermore, according to the first embodiment, the user can understand the extent to which the heat dissipation conditions have been improved through his / her own actions. In addition, the effect of the improvement, such as the reduction rate of annual power consumption, can be confirmed. This can encourage the user to establish new actions.

[0081] The evaluation unit 200 in the first embodiment may be built into the refrigerator 100, or may be set in a place different from the refrigerator 100, such as a cloud environment. In addition, if the evaluation unit 200 is built into the refrigerator 100 having a communication function, it is not necessary for the evaluation unit 200 to have an independent communication function. That is, the evaluation unit 200, the output unit 201, and the storage unit 202 may all be built into the refrigerator 100, or may all be set outside the refrigerator 100, or may only be partially set outside the refrigerator 100.

[0082] [Second embodiment]

[0083] Next, refer to Figure 6 to Figure 8 , a second embodiment of the present invention is described.

[0084] <Structure of the environmental sensing system Za of the heat pump washer-dryer>

[0085] Figure 6 1 is a diagram showing a configuration of an environment sensing system Za of a heat pump washer-dryer in accordance with Embodiment 2. In Embodiment 2, an environment sensing system Za of a heat pump washer-dryer that evaluates and notifies the heat dissipation conditions of the surrounding environment of a heat pump washer-dryer 500 is shown.

[0086] The environment sensing system Za of a heat pump washer-dryer includes a heat pump washer-dryer 500 (cooling and heating device), an evaluation unit 200 , an output unit 201 , and a selection unit 203 .

[0087] (Heat Pump Washer-Dryer 500)

[0088] The heat pump washer-dryer 500 has a washing tub 501 (clothing holding portion), a door 502, and a motor 503. In addition, the heat pump washer-dryer 500 has a blower 504 (air supply device), a duct 505, and an ambient temperature sensor 506. In addition, it has a heat pump unit 510, a compressor 511, an evaporator 512, a condenser 513, and an expansion valve 514 connected in a ring shape. In addition, it has an air intake port 522 and an air intake valve 523.

[0089] The user opens door 502, puts the laundry to be washed into washing tub 501, and closes door 502. Thus, the laundry is held in washing tub 501. Then, motor 503 rotates washing tub 501, thereby performing a washing process, a dehydration process, and a drying process. Washing water, rinsing water, etc. are discharged through drain pipe 521.

[0090] After the washing process and the dehydration process are completed, the drying process is performed. When the drying process starts, wet clothes are put into the washing tub 501. When the drying process starts, the blower 504 and the heat pump cycle H work.

[0091] The refrigerant (heat transfer medium) circulates in the flow paths in which the evaporator 512, the compressor 511, the condenser 513, and the expansion valve 514 are respectively connected in a ring shape, thereby forming a heat pump cycle H. The evaporator 512 is a heat exchanger that absorbs the heat of the air flowing into the heat pump. The compressor 511 driven by the input energy compresses the gas-phase refrigerant evaporated in the evaporator 512. The condenser 513 is a heat exchanger that releases the heat of the high-temperature gas-phase refrigerant compressed by the compressor 511 to the air. In the condenser 513, the gas-phase refrigerant is liquefied to become a liquid refrigerant. The expansion valve 514 expands the liquid refrigerant coming out of the condenser 513 to become a low-pressure and low-temperature two-phase refrigerant, and sends it to the evaporator 512.

[0092] The blower 504 operates to generate air flow in the flow path including the washing tub 501, the heat pump unit 510, the duct 505, and the blower 504. The moisture contained in the wet clothes is mixed with the air in the washing tub 501 to form a high humidity state, and flows into the heat pump unit 510, and sequentially passes through the evaporator 512 and the condenser 513. In the evaporator 512, the temperature of the air decreases and the air is dehumidified. In the next condenser 513, the low-temperature air after dehumidification is heated to a high temperature, and the high-temperature, low-humidity air flows into the washing tub 501 again through the duct 505 and the blower 504.

[0093] During the operation of the compressor 511, when the operating load 303 of the compressor 511 is high, in order to suppress the operating load 303, the air intake valve 523 is opened, and the surrounding air is sucked in from the air intake port 522, so that the temperature and humidity of the air coming out of the washing tank 501 are reduced in advance before flowing into the heat pump unit 510.

[0094] When the heat pump washer-dryer 500 is in an environment with poor heat dissipation conditions, the temperature of the surrounding air rises due to the heat dissipation from the housing body (heat dissipation portion to the outside). Therefore, if the heat dissipation conditions are poor, high-temperature air is sucked in, and the temperature of the air coming out of the washing tub 501 does not drop and flows into the heat pump unit 510. As a result, the energy required for dehumidification increases, that is, the operating load 303 of the compressor 511 increases. The ambient temperature sensor 506 measures the ambient temperature of the heat pump washer-dryer 500.

[0095] (Selection section 203)

[0096] The selection unit 203 is composed of a CPU (Central Processing Unit) and the like, executes processing to select recommended products when purchasing replacements based on the evaluation results of the evaluation unit 200 , and transmits information on the selected recommended products to the output unit 201 .

[0097] Here, the selection of recommended products may also use the evaluation results of the evaluation unit 200, the equipment information of the currently used product (equipment information of the cooling and heating device), the market, warehouse, or the inventory management information and product information of the goods compared with the production plan. Specifically, using the above information, the suitability of the product relative to the current heat dissipation conditions is calculated, and the product with a higher suitability than the currently used product is selected as the recommended product. For example, for users whose heat dissipation conditions are evaluated as poor, a product that is smaller than the current one, a product with a different location of the air inlet 522, a product with less heat generation when drying, etc. are selected.

[0098] <Evaluation method of heat dissipation conditions in the surrounding environment>

[0099] Figure 7 305 is a diagram showing an evaluation object and an evaluation period 305 in the evaluation unit 200. Figure 6 .exist Figure 7 In FIG. 5 , the horizontal axis represents time, the vertical axis of the upper figure represents temperature, and the vertical axis of the lower figure represents the operating load 303 of the compressor 511. Figure 7 The upper figure shows the time variation of the actual ambient temperature 301 (the room temperature of the room where the heat pump washer-dryer 500 is installed) and the ambient temperature sensor value 302 (the value of the ambient temperature sensor 506), and the lower figure shows the time variation of the operating load 303 of the compressor 511.

[0100] Due to the heat dissipation from the housing body, the temperature of the air in the installation space rises, and thus the ambient temperature sensor value 302 is higher than the actual ambient temperature 301, which is expressed as Figure 7 The temperature deviation 304 in the heat pump washer-dryer 500 is greater when the surrounding environment is more difficult to dissipate heat. Therefore, the heat dissipation condition of the surrounding environment is estimated by evaluating the temperature deviation 304.

[0101] A method for estimating the temperature deviation 304 based only on the ambient temperature sensor value 302 in the heat pump washer-dryer 500 is described. First, when the compressor 511 is operating, heat is dissipated from the housing body, and the temperature around the housing rises from the actual ambient temperature 301. The change 306 at this time is proportional to the temperature deviation 304, so by obtaining the change 306, the temperature deviation 304 can be indirectly evaluated. The evaluation period 305 of the change 306 is set to the drying process in which the compressor 511 is operating, and the change 306 is the difference between the ambient temperature sensor value 302 at the start of the drying process and the ambient temperature sensor value 302 at the end of the drying process. Here, the ambient temperature sensor value 302 at the start of the drying process can also be replaced by the value at the start of the heat pump washer-dryer 500. In addition, the ambient temperature sensor value 302 at the end of the drying process can also be replaced by the value when the ambient temperature sensor value 302 becomes constant after a predetermined time or more from the start of the drying process. Thus, in the heat pump washer-dryer 500 in which the power may be cut off after the operation is completed, the change amount 306 can be calculated.

[0102] That is, the predetermined evaluation period 305 is determined based on one or both of the stop time and the start time of the driving source.

[0103] The processing of the evaluation unit 200 is based on Figure 3 Flowchart shown.

[0104] <Display screen 400>

[0105] When the setting environment is judged to be poor, as in embodiment 1, notification is made of methods for improving heat dissipation conditions such as removing obstacles, or methods of use suitable for current heat dissipation conditions. However, in a second embodiment, model selection when purchasing or replacing based on heat dissipation conditions is described as other timed notification information.

[0106] Figure 8 This is a diagram showing an example of a display screen 400 displayed on the output unit 201 when a recommended model is proposed as a product purchase replacement target based on the heat dissipation conditions evaluated by the evaluation unit 200 .

[0107] The timing for displaying the recommended replacement model on the display screen 400 is the timing when the current product usage period becomes longer than a predetermined period, the timing when the user operates the input unit 205 that has a display for applying for a replacement product purchase proposal, etc. Alternatively, the timing may be determined in cooperation with a system that prompts the user with an appropriate selling timing for the product in use. That is, the timing is generally different from the timing for displaying the evaluation method of the heat dissipation condition in the first embodiment.

[0108] The display screen 400 includes an evaluation result display section 410 and a product information display section 450. The product information display section 450 also includes a used product information display section 451 and a purchase replacement product suggestion section 452.

[0109] The information of the currently used product obtained from the operation information is displayed in the product information display unit 451. The product information refers to the model, washing capacity, size, energy saving performance, etc. of the currently used product. In addition, the suitability rate for the current heat dissipation conditions calculated by the selection unit 203 is displayed. In addition, the appearance of the product is displayed.

[0110] The purchase replacement product proposal unit 452 displays information on the recommended product selected by the selection unit 203. The recommended product information refers to the recommended product model, washing capacity, size, energy saving performance, etc. In addition, the suitability calculated by the selection unit 203 is displayed. In addition, the appearance of the product is displayed.

[0111] In addition, in the purchase replacement product proposal unit 452, in addition to new products, second-hand products or recycled products shown in the second-hand product or recycled product information display unit 453 can be presented. That is, when outputting recommended products to the output unit 201, both second-hand products or recycled products and new products can be output. In addition, it can be configured so that the user can select whether to display second-hand products or recycled products.

[0112] In addition, the display screen 400 may include an input unit 205, which can be moved to a screen where the recommended product can be purchased or temporarily held. This can reduce the burden on the user when purchasing or replacing. That is, the user can enter the purchase screen of the recommended product from the input unit 205, or can temporarily hold the recommended product.

[0113] According to the second embodiment, although the heat pump washer-dryer 500 has not failed, it can be detected that the operating load 303 of the compressor 511 has increased due to poor heat dissipation conditions in the surrounding environment.

[0114] In addition, according to the second embodiment, the user can understand the recommended products that have a high suitability rate for the heat dissipation conditions compared to the currently used products, and can compare the information of the products, thereby easily selecting products that the user is satisfied with. In addition, it is possible to move to a screen where the recommended product can be purchased or temporarily held. As a result, the user can purchase and replace products that are more suitable for the heat dissipation conditions with less burden, thereby promoting the user's willingness to purchase and replace. In addition, by purchasing and replacing according to the notification, the user can use the device more appropriately after the purchase and replacement, and can enjoy the advantages of reduced electricity bills, etc.

[0115] Furthermore, according to the second embodiment, the user can choose to purchase a replacement product from second-hand products or recycled products, thereby promoting the improvement of the user's awareness of recycling and reuse, and the user can purchase the product at a lower price than a new product.

[0116] [Third Embodiment]

[0117] Next, refer to Figures 9 to 11 , a third embodiment of the present invention is described.

[0118] <Structure of the environment sensing system Zb of the heat pump water heater>

[0119] Fig. 9 1 is a diagram showing a configuration of an environment sensing system Zb for a heat pump water heater according to a third embodiment. In the third embodiment, an environment sensing system Zb for a heat pump water heater that evaluates and notifies a heat radiation condition of a heat pump water heater 700 is shown.

[0120] The environment sensing system Zb for a heat pump water heater includes a heat pump water heater 700 , an evaluation unit 200 , an output unit 201 , and an input unit 205 .

[0121] (Heat Pump Water Heater 700)

[0122] The heat pump water heater 700 includes a heat pump unit 710, a hot water storage unit 720, and a control unit 204. The heat pump unit 710 is equipped with a heat pump cycle H that heats cold water to boil hot water during boiling operation. The hot water storage unit 720 is equipped with a water side cycle (heating flow path) W that operates during boiling operation and a hot water supply flow path group F that operates during hot water supply. The control unit 204 will be described later.

[0123] The heat pump cycle H is a flow path in which a compressor (driving source) 711, a water / refrigerant heat exchanger (heat dissipation part, temperature adjustment device) 712, an expansion valve (expansion device) 713, and an evaporator (heat absorption part) 714 are connected in a ring shape. In addition, the evaporator 714 has a blower fan 715. The various structures of the heat pump cycle H will be described later.

[0124] (Water side circulation)

[0125] The water side circulation is a structure in which the hot water storage container 721, the boiling circulation pump 722, and the water / refrigerant heat exchanger 712 are connected in a ring shape. In addition, the hot water supply flow path group F is composed of a flow path connecting the tap water pipe 724, the hot water storage container 721, and the hot water supply port (water supply device) 723 in series, and a pipe 725 directly connecting the tap water pipe 724 and the inlet of the hot water supply port.

[0126] (Heat pump cycle H)

[0127] The heat pump water heater 700 includes an ambient temperature sensor 731 for measuring the outside air temperature. The ambient temperature sensor 731 is disposed close to the air intake side of the evaporator 714 .

[0128] The heat pump water heater 700 also includes a control unit 204. The control unit 204 has a communication function, and transmits operation information such as the rotation speed of the compressor 711 and information (temperature information) of the temperature measured by the ambient temperature sensor 731 to the evaluation unit 200. In addition, the heat pump water heater 700 is controlled by executing a pre-assembled operation plan or an operation plan provided from the outside.

[0129] use Fig. 9 The operation of the heat pump water heater 700 will be briefly described.

[0130] After the refrigerant is compressed by the compressor 711 to a high temperature and high pressure state, the cold water sent from the hot water storage container 721 by the boiling circulation pump 722 is heated in the water / refrigerant heat exchanger 712, and instead of dissipating its own heat, heat exchange is performed.

[0131] After the refrigerant passes through the expansion valve 713 and becomes a low-temperature, low-pressure state, it receives heat from the external air sent by the air supply fan 715 in the evaporator 714 and then flows into the compressor 711 again. In addition, in the water / refrigerant heat exchanger 712, water and refrigerant flow in directions relative to each other, and the hot water heated by the refrigerant and having a higher temperature returns to the hot water storage tank 721.

[0132] When hot water is supplied, hot water flows from the upper part of the hot water storage container 721 to the hot water supply port, and tap water is supplied from the tap water pipe 724 to the hot water supply port via the pipe 725. Hot water and tap water are mixed at the inlet of the hot water supply port and then flow out from the hot water supply port. In addition, when hot water is supplied, the opening of the valve 726 is adjusted. The tap water is replenished from the tap water pipe 724 to the hot water storage container 721 whose pressure is reduced due to the flow of hot water via the valve 726.

[0133] Next, the operation of the evaporator 714 will be described. When the heat pump cycle H is driven, the air supply fan 715 rotates, thereby generating a flow of external air from the evaporator 714 toward the air supply fan 715. Fig. 9 As shown, the refrigerant flowing into the evaporator 714 absorbs heat from the outside air and is then discharged from the evaporator 714 .

[0134] During the operation of the heat pump water heater 700, air with a lowered temperature is discharged from the evaporator 714 by absorbing heat in the evaporator 714. At this time, when the heat pump unit 710 is set in an extremely narrow place, or when an obstacle is accidentally set on the intake surface or the exhaust surface, sometimes a circulation flow in which the exhaust returns to the intake again or the air path of the air flowing in the evaporator 714 is blocked. For example, there may be flying objects on a thin plate due to a typhoon, strong wind, etc., or the intake side of the evaporator 714 may be blocked due to garbage accumulation. If this phenomenon continues, the ambient temperature of the evaporator 714 decreases, and the detected temperature of the ambient temperature sensor 731 set on the intake side of the evaporator 714 also decreases. The refrigerant absorbs heat from the low-temperature outside air, so the operating load increases in order to maintain the amount of heat absorbed.

[0135] <Evaluation method of heat dissipation conditions in the surrounding environment>

[0136] Fig.10 305 is a diagram showing an evaluation object and an evaluation period 305 in the evaluation unit 200. Fig. 9 .exist Fig.10 In FIG. 7 , the horizontal axis represents time, the vertical axis of the upper figure represents temperature, and the vertical axis of the lower figure represents the operating load 303 of the compressor 711. Fig.10 The upper figure shows the time variation of the actual ambient temperature 301 (the outdoor external air temperature where the heat pump water heater 700 is installed) and the ambient temperature sensor value 302 (the value of the ambient temperature sensor 731), and the lower figure shows the time variation of the operating load 303 of the compressor 711.

[0137] As described above, when the air flow in the place where the heat pump unit 710 is installed is stagnant, the air whose temperature is lowered due to the absorption of heat in the evaporator 714 is discharged to the installation space, and thus the ambient temperature sensor value 302 is lower than the actual ambient temperature 301, which is expressed as Fig.10 The temperature deviation 304 in the heat pump water heater 700 is greater when the surrounding environment is less likely to absorb heat. Therefore, the heat dissipation condition of the surrounding environment is estimated by evaluating the temperature deviation 304.

[0138] A method for estimating the temperature deviation 304 based only on the ambient temperature sensor value 302 in the heat pump water heater 700 is described. First, when the compressor 711 is operating, the heat absorption in the evaporator 714 begins, and the temperature around the casing decreases from the actual ambient temperature 301. The change amount 306 at this time is proportional to the temperature deviation 304, so by obtaining the change amount 306, the temperature deviation 304 can be indirectly evaluated. The evaluation period 305 of the change amount 306 is during the boiling when the compressor 711 is operating, and the change amount 306 is the difference between the ambient temperature sensor value 302 at the start of boiling and at the end of boiling.

[0139] Here, the ambient temperature sensor value 302 at the end of boiling may be replaced by a value when the ambient temperature sensor value 302 becomes constant after a predetermined time or longer has passed since the start of boiling. In this way, the change amount 306 in the heat pump water heater 700 can be calculated.

[0140] That is, the predetermined evaluation period 305 is determined based on one or both of the stop time and the start time of the driving source.

[0141] The processing of the evaluation unit 200 is based on Figure 3 In addition, Figure 3 The temperature sensor 120 different from the ambient temperature sensor 731 is, for example, a sensor separately installed by the user, an ambient temperature sensor of another device, etc. Thus, the outside temperature of the place where the heat pump unit 710 is installed can be grasped.

[0142] <Display screen 400>

[0143] Fig.11 4 is a diagram showing an example of a display screen 400 displayed by the output unit 201 . The display screen 400 includes an evaluation result display unit 410 , a rating result display unit 411 , a detail display unit 420 , a proposal content display unit 430 , and the input unit 205 .

[0144] When the installation environment of the heat pump water heater 700 is judged to be poor, first, as in Embodiment 1, a message prompting the user to confirm the surrounding conditions is notified. When it is known that there is no abnormality and the user of the installation location cannot improve the cause, the proposed content of the operation plan suitable for the heat dissipation conditions can be displayed. Here, the operation plan is provided in the form of an operation control program for changing the operation control of the heat pump unit 710 according to the evaluation result of the installation environment, and the operation of the heat pump water heater 700 is controlled by being executed by the control unit 204.

[0145] For example, for users with poor heat dissipation conditions, such as Fig.11As shown in the proposed content display unit 430 in the figure, an operation plan for heating water during the day is displayed. By operating during the day when the temperature is relatively high, the ambient temperature is less likely to drop compared to the case of operating at night, and the operation load can be reduced. Alternatively, an operation plan for operating at a low output during a time period when the frequency of use is not high can be proposed. By executing this process, the amount of heat absorbed per unit time can be suppressed, and the drop in the ambient temperature can be suppressed.

[0146] In the proposed content display unit 430, in addition to the content of the proposed operation plan, a comparison with the current operation status can be displayed. In addition, the effect of executing the target operation plan can also be displayed, such as the annual power consumption reduction rate.

[0147] The user can select an operation plan that is considered to be executable from the operation plans displayed on the proposal content display unit 430 , and apply for execution of the operation plan through the input unit 205 .

[0148] The input unit 205 sends an execution request of the operation plan to the control unit 204. After receiving the request, the control unit 204 executes the target operation plan. In addition, the input unit 205 can also request to stop or change the executed operation plan.

[0149] According to the third embodiment, although the heat pump water heater 700 has not failed, it can be detected that the operating load 303 of the compressor 711 has increased due to poor heat dissipation conditions in the surrounding environment.

[0150] Furthermore, according to the third embodiment, even in a cooling and heating device such as a heat pump water heater 700, which is difficult to easily change the surrounding environment, the user can know the operation plan suitable for the heat dissipation conditions, and can execute the target operation plan only by operating on the display screen 400. Furthermore, by executing the operation plan, the user can use the device more appropriately, and can enjoy advantages such as reduction in electricity bills and extended product life.

[0151] As described above, the environment sensing system of the present embodiment is an environment sensing system of a cold and heat device (e.g., refrigerator 100) having a driving source for generating cold and heat (e.g., compressor 110), a heat absorbing and dissipating portion to the outside (e.g., condenser 112), and an external temperature detecting portion (e.g., ambient temperature sensor 105), and comprises: an evaluation portion 200 that evaluates a heat absorbing and dissipating condition indicating whether the surrounding environment of the cold and heat device is suitable for heat absorbing and dissipating, based on the amount of change in the detected temperature of the external temperature detecting portion during a predetermined evaluation period; and an output portion 201 that notifies the evaluation result of the heat absorbing and dissipating condition evaluated by the evaluation portion 200. Thus, the heat dissipation condition of the surrounding environment is evaluated based on the operation data of the device, and a notification based on the evaluation result is made, thereby enabling the user to perceive poor heat dissipation, and as a result, the user's behavior can be prompted to change. Furthermore, by taking action based on the notification, the user can use the device more appropriately, and can enjoy advantages such as reduced electricity bills and extended device life.

[0152] In addition, the environment sensing system is an environment sensing system for heat dissipation conditions of a heat and cold device having a driving source for generating heat and cold, a heat dissipation portion to the outside, and an external temperature detection portion, and comprises: an evaluation unit 200, which evaluates the heat dissipation condition indicating whether the surrounding environment is suitable for heat dissipation based on the temperature difference between the room temperature of the room with the heat and cold device (refer to the first embodiment) or the external air temperature (refer to the third embodiment) and the detection temperature of the external temperature detection portion; and an output unit 201, which notifies the evaluation result of the heat dissipation condition evaluated by the evaluation unit 200.

[0153] Fig.12 901 is a diagram showing the hardware structure of a computer. For example, the evaluation unit 200 and the like are configured as a computer 900 having a CPU 901, a RAM 902, a ROM 903, a HDD 904, a communication I / F 905, an input / output I / F 906, and a medium I / F 907. The communication I / F 905 is connected to an external communication device 915. The input / output I / F 906 is connected to an input / output device 916. The medium I / F 907 reads and writes data from a recording medium 917. Furthermore, the CPU 901 improves control of each processing unit by executing a program (also referred to as an application program, or an application (app) for short) read into the RAM 902. Furthermore, the program can also be distributed via a communication line or recorded on a recording medium 917 such as a CD-ROM.

[0154] The present invention is not limited to the above-described embodiments, and includes various modifications. For example, the above-described embodiments are embodiments described in detail in order to explain the present invention in an easy-to-understand manner, and are not limited to having all the structures described. In addition, a part of the structure of a certain embodiment can be replaced with the structure of another embodiment, and the structure of another embodiment can be added to the structure of a certain embodiment. In addition, with respect to a part of the structure of each embodiment, other structures can be added, deleted, or replaced.
