Background
A dishwasher is an apparatus for automatically washing dishes. The dish washing machine can greatly reduce tedious manual labor, is simple and convenient to operate and high in automation degree, so that the dish washing machine is favored by more and more consumers.
At present, the washing water used for washing a dish washer is tap water at normal temperature, and also water which reaches a certain temperature after being heated. The applicant found after comparing the cleaning effect based on different water temperature conditions: the washing effect of the dishwasher is positively correlated with the temperature of the water being washed over a range of temperatures. Generally, the effect of direct washing with tap water at normal temperature is inferior to that of washing with heated water.
In order to ensure that the dishwasher has a better cleaning effect, the water for washing can be raised to a certain temperature. However, the applicant found the following problems:
if the water to be washed is heated by the heating function of the existing dish washer, the washing time of the dish washer can be prolonged.
If the external heat source is used to directly supply hot water to the dish washer, the water inflow required for one washing of the dish washer is about 3 liters, and when the water inflow is 2.5L/min, the water inflow time of the dish washer is usually about 1 minute. In this short water intake time, the water reaching the inside of the dishwasher is usually cold water in the heat source-to-dishwasher line, while all or most of the hot water provided by the hot water device has not reached the dishwasher, which results in a substantial increase in the temperature of the water for washing the dishwasher and thus in a substantial improvement in the washing effect.

The utility model provides a combined supply system which can ensure that a cleaning machine has a better cleaning effect, shorten the total cleaning time and improve the use experience of a user.
Referring to fig. 1 to 5, in an embodiment of the present utility model, a co-generation system is provided, which may mainly include: a cleaning machine 1 and a water heating device 2. The cleaning machine 1 and the water heating device 2 are connected through a pipeline.
The cleaning machine 1 may be a dishwasher for cleaning objects to be cleaned such as tableware, kitchen ware, etc., the tableware may include bowls, plates, dishes, chopsticks, etc., and the kitchen ware may include pans, basins, etc. In addition to this, the washing machine 1 may also be used for washing other kinds of articles, for example, when the washing machine 1 is used for washing laundry, it may correspond to a washing machine. In the embodiment of the present disclosure, the washing machine 1 is mainly described by way of example with reference to a dishwasher, and other similar application scenarios may be referred to in the present disclosure, and the disclosure will not be described in detail here.
The washing machine 1 is provided with a water inlet 10, through which water supplied from the outside is supplied into the washing machine 1, so that washing water is supplied to the washing machine 1. In general, the washing machine 1 is further provided with a water cup 11, a washing pump 12, a shower arm 15, a drain pump 14, a drain port 13, and the like. The washing machine 1 generally comprises a plurality of washing modes, for example: pre-wash mode, power wash mode, energy saving wash mode, etc. When the washing machine 1 enters a certain washing mode, water with a preset water quantity can be supplied into the water cup 11 through the water inlet 10; the washing pump 12 is started, and the washing pump 12 drives water in the water cup 11 into the spray arm 15, and then the water is sprayed to the object to be washed by the spray arm 15, so that the object to be washed is washed. The cleaned water is collected again into the water cup 11 under the action of gravity, so that the water is reused. When one of the washing modes is completed, the drain pump 14 may be activated to drain the water from the cup 11 and finally through the drain port 13.
The water heating device 2 may be a device capable of outputting hot water to the outside. Specifically, the water heating device 2 may be any one of the following: gas water heater, hanging stove, heat pump water heater, electric water heater, solar water heater, etc. Of course, the specific form of the water heating device 2 is not excluded from the other forms in the prior art, and the present application is not limited thereto. In the embodiment of the present specification, the water heater 2 is mainly described by taking a gas water heater as an example, and other similar application scenarios can be referred to in the present specification, and the present application will not be described in detail here.
The water heating device 2 is provided with a water inlet 21 and a water outlet 22. The water inlet 21 and the water outlet 22 are used for communicating with an external water source 7, a water supply end and the like through a pipeline.
Referring to fig. 1 to 4, in some embodiments, the water inlet 21 and the water outlet 22 of the water heating device 2 are connected to the water inlet 10 of the cleaning machine 1 through a co-feeding pipe. Correspondingly, the combined supply system can also comprise a switching device, a water pump 4 and a controller which can be in communication connection with the cleaning machine 1, the hot water device 2, the water pump 4 and the switching device. The switching device comprises a first state and a second state, and when the switching device is in the first state, the water heating device 2 can be matched with at least part of the combined supply pipeline to form a first circulating waterway; when the switching device is in the second state, the water outlet 22 of the water heating device 2 is communicated with the water inlet 10 of the cleaning machine 1, and the water heating device 2 supplies water to the cleaning machine 1.
When the switching device is in the first state, the water heating device 2 and the combined supply pipeline are matched to form a first circulating water path, and after the water heating device 2 and the water pump 4 are started, water in the first circulating water path can be heated to a preset temperature by the water heating device 2 under the driving of the water pump 4. Subsequently, when the washing machine 1 needs to be started for a washing operation, the state of the switching device can be switched from the first state to the second state, and the water outlet 22 of the hot water device 2 is communicated with the water inlet 10 of the washing machine 1 by using the switching device, so that the hot water device 2 provides water with a predetermined temperature to the washing machine 1. Because before the water heater 2 supplies water to the cleaner 1, the water heater 2 and at least part of the combined supply pipeline can be matched to form a first circulating water path, the water temperature in the pipeline is improved by utilizing the heating function of the water heater 2, and the water heated by the water heater 2 can enter the cleaner 1 through part of the first circulating water path, which is equivalent to shortening the length of a cold water section between the water heater 2 and the cleaner 1, and improving the water temperature supplied to the cleaner 1, thereby ensuring that the cleaner 1 has better cleaning effect in a shorter cleaning time.
Wherein, the preset temperature required to reach the water temperature in the first circulating water path can be set by a user (namely, the preset temperature is the target water temperature set by the user).
Alternatively, the predetermined temperature may be a temperature separately set based on the cleaning water temperature required for the cleaning machine 1, and the predetermined temperature may be set at the time of shipment of the cleaning machine 1 and stored in the controller.
Alternatively, the predetermined temperature may be a temperature determined based on a required washing water temperature of the washing machine 1 in combination with heat loss of the pipe line between the hot water device 2 and the washing machine 1. When the predetermined temperature is a temperature determined based on a required washing water temperature of the washing machine 1 in combination with heat loss of the pipe between the hot water apparatus 2 and the washing machine 1, the predetermined temperature is a sum of the washing water temperature and a pipe loss temperature difference.
Wherein the water pump 4 is used for providing driving force for water flow. The water pump 4 may be disposed at any position of the first circulation water path. Specifically, the water pump 4 may be integrally provided in the water heating device 2, may be provided in a combined supply line, or may be provided in a washer. For example, when the water heating device 2 is a zero cold water type water heater, the water pump 4 is arranged inside the water heating device 2, and the water pump 4 can be utilized by the water pump 4 arranged inside the water heating device 2 without additional arrangement.
The switching device has a plurality of different states, and when the switching device switches between the different states, the switching device can be used for changing the communication relationship between the pipelines, and by changing the communication relationship between the pipelines, the switching device can be used for switching the communication relationship between the water inlet 21, the water outlet 22 of the water heating device 2 and the water inlet 10 of the cleaning machine 1.
The controller can be in communication connection with the cleaning machine 1, the water heating device 2, the water pump 4 and the switching device, and can directly or indirectly control various components in the combined supply system according to the acquired signals. Specifically, the controller may be provided in the washing machine 1; alternatively, the controller may be provided in the water heating device 2; alternatively, the controllers may be independently provided; alternatively, the controller may be disposed at a cloud end, and the water heating device 2 and the cleaning machine 1 are provided with communication modules.
When the controller is provided in the washing machine 1, the controller may be provided integrally in the controller of the washing machine 1 itself, for example on a control chip of the washing machine 1. The controller may communicate with the water heating device 2 by wired or wireless means. For example, when the controller communicates with the water heating device 2 in a wireless manner, the water heating device 2 may be provided with a communication module, and the controller is communicated with the communication module, so as to receive a control signal sent by the controller, or feedback a current state signal of the water heating device 2 to the controller.
When the controller is provided in the water heating device 2, the controller may be provided integrally in the controller of the water heating device 2 itself, for example on a control chip of the water heating device 2. The controller may communicate with the washing machine 1 by wired or wireless means. For example, when the controller communicates with the cleaning machine 1 in a wireless manner, the cleaning machine 1 may be provided with a communication module, and the controller may be communicated with the communication module, so as to receive a control signal sent by the controller, or feedback a status signal of the current cleaning machine 1 to the controller.
When the controller is provided independently, the controller can establish communication connection with the washing machine 1 and the hot water apparatus 2 respectively by wired or wireless means. For example, the controller may be a PLC controller provided independently to the washing machine 1 and the water heating apparatus 2, and of course, the specific form of the controller is not limited to the above example, and the present application is not limited thereto. In addition, the installation position of the controller can be flexibly set according to the installation environment of the user, and the application is not particularly limited herein.
When the controller is arranged at the cloud, the cloud can store a control program for controlling the operation of the hot water device 2 and the cleaning machine 1, the hot water device 2 and the cleaning machine 1 are provided with a communication module, and the hot water device 2 and the cleaning machine 1 can respectively establish communication connection with the controller positioned at the cloud by using the communication module, so that a control signal sent by the cloud controller is received, or a current state signal is fed back to the cloud controller.
In some embodiments, for the water heater 2 with the zero cold water function, the water inlet 21 of the water heater 2 can be further communicated with the water return pipeline 23, the water outlet 22 can be further communicated with the hot water pipeline 24, and the water heater 2 can be matched with the water return pipeline 23 and the hot water pipeline 24 to form a second circulating water path.
When the water heating device 2, the water return pipeline 23 and the hot water pipeline 24 are matched to form a second circulating water path, namely the water heating device 2 has a zero cold water function. When the user turns on the water terminal for water, the water heating device 2 with the zero cold water function can immediately supply water with proper temperature to the user without emptying the cold water section in the pipeline.
Specifically, for the water heating device 2 with the zero cold water function, besides the heating module, a water pump 4 is generally arranged in the water heating device, and after the water pump 4 is started, a driving force can be provided for water flow in the second circulating waterway. The water in the second circulation waterway may be heated while passing through the heating module of the water heating device 2, so that the water in the second circulation waterway is maintained above a predetermined temperature.
For example, when the water heater 2 with the zero cold water function is not in use by a user, the water return pipeline 23 and the hot water pipeline 24 can be connected by the constant pressure water return valve 25, and the water in the second circulating water path can circulate in the hot water pipeline 24, the water return pipeline 23 and the water heater 2 under the driving of the water pump 4, and the water is heated by the heating module when flowing through the heating module until the proper water temperature is reached.
In this description, the constant pressure water return valve 25 is mainly used as an example for illustration, and other control valves can be used for analogy reference, so that the application is not described here one by one.
In this embodiment, the second circulation water path and the first circulation water path of the co-generation system may be turned on at the same time, or alternatively turned on.
For example, in the case where the second circulation water path is in the conductive state, the first circulation water path is in the non-conductive state when the user does not use the demand of the washer 1, that is, the water demand signal on the washer 1 side is not recognized.
If the user has a need to use the washing machine 1, that is, the water demand signal on the washing machine 1 side is recognized, the first circulation water path may be turned on by the switching device if the second circulation water path is in the on state. Generally, most of water can be automatically split into the first circulation pipeline because the pipe resistance of the first circulation pipeline is smaller than that of the second circulation pipeline.
If the user has a need to use the washing machine 1 when the second circulation waterway is in a conductive state, that is, a water demand signal on the side of the washing machine 1 is recognized, the constant-pressure water return valve 25 may be controlled to be in a disconnected state so that the second circulation waterway is in a non-conductive state, and the first circulation waterway is conducted through the switching device. In addition, when the other water terminal side has a need to use hot water and the cleaner 1 side has no need to use, the first circulation water path and the second circulation water path may be both non-conductive.

In one embodiment, the co-supply system may further include a first temperature sensor 51 for detecting a water temperature in the first circulation water path, and the switching device may switch from the first state to the second state when the temperature detected by the first temperature sensor 51 reaches a target water temperature.
In the present embodiment, the first temperature sensor 51 is mainly used for detecting the water temperature in the first circulation water path, and when the first temperature sensor 51 detects that the current water temperature in the first circulation water path reaches the target water temperature, it means that the water heating device 2 can supply water with a sufficiently high temperature to the cleaning machine 1 for cleaning at this time, and at this time, the switching device can be switched from the first state to the second state. When the switching device is in a first state, a first circulating water path can be formed; when the switching device is in the second state, the water outlet 22 of the water heating device 2 can be connected to the water inlet 10 of the washing machine 1.

Of course, the first temperature sensor 51 is not limited to the above-mentioned installation position, and may be installed at another position in the first circulation water path, as long as it directly or indirectly reflects the water temperature supplied to the washing machine 1 by the current hot water apparatus 2.
In one embodiment, the washing machine 1 is provided with a water cup 11, a second temperature sensor 52 for detecting the temperature of water in the water cup 11, and a heating unit capable of heating water in the water cup 11 to a set washing temperature when the temperature detected by the second temperature sensor 52 is lower than the set washing temperature.
In the present embodiment, the cleaning machine 1 may be provided with a cup 11, and the cup 11 is used for receiving water for cleaning. The washing machine 1 may also be provided with a second temperature sensor 52, which second temperature sensor 52 may be used to detect the temperature of the water in the water cup 11. Furthermore, the washing machine 1 may be provided with a heating unit, which may be provided in particular at any position in the washing circuit of the washing machine 1.
Specifically, the cleaning circuit of the cleaning machine 1 includes: the water cup 11, the washing pump 12, the spray arm 15 and the communication pipeline connected between the water cup 11 and the washing pump 12 and between the washing pump 12 and the spray arm 15. The heating unit may be provided in any or a combination of the following: a water cup 11, a washing pump 12, a spray arm 15 and a communication pipeline.
When the second temperature sensor 52 detects that the current water temperature in the water cup 11 is lower than the set washing temperature, the heating unit may be activated to heat the water in the water cup 11 to the set washing temperature.
In this embodiment, taking the heating unit integrally disposed in the water cup 11 as an example, when the second temperature sensor 52 detects that the current water temperature in the water cup 11 is lower than the set cleaning temperature, the heating unit may be started first, the water in the water cup 11 is heated to the set cleaning temperature, and then the washing pump 12 and the spray arm 15 are started to perform cleaning operation; alternatively, the washing pump 12 and the shower arm 15 may be activated to perform the cleaning operation simultaneously with the activation of the heating means.
Wherein the set washing temperature may be stored in a program inside the washing machine 1. For the washing machine 1, it may comprise a plurality of washing modes, such as: strong washing, quick washing, energy-saving washing, etc. In each cleaning mode, different cleaning time, cleaning water temperature and the like can be correspondingly stored. Of course, the set cleaning temperature can also be set and modified by a user according to the requirements. For example, when a user is washing certain heavy oil heavy dirty dishes, he may set the set washing temperature higher.
In one embodiment, the combined supply system is further provided with a flow detection member 53 for detecting the amount of water entering the washing machine 1, and a washing pump 12 in communication with the water cup 11, and the washing pump 12 is started after the amount of water currently entering the washing machine 1 reaches a preset amount of water based on a flow signal detected by the flow detection member 53.
In the present embodiment, the cleaning machine 1 is generally provided with a wash pump 12 in communication with the water cup 11, and the wash pump 12 is configured to drive water in the water cup 11 into the shower arm 15 to spray the water toward the object to be cleaned. The co-feed system may also be provided with a flow detector 53, which flow detector 53 is used to detect the amount of water entering the washing machine 1. When the flow signal detected by the flow detecting member 53 indicates that the current water amount entering the cleaning machine 1 reaches the preset water amount, the cleaning pump 12 is started again to drive the spray arm 15 to rotate, so as to spray and clean the cleaned object. The preset water amount may be about 3 liters, and of course, the preset water amount may be differently set according to the specific model of the cleaning machine 1, and the present application is not limited thereto.
Furthermore, the way of measuring the amount of water entering the washing machine 1 is not limited to the above examples, but it can also be realized in other ways. For example, a level gauge may be provided in the cup 11, with which the current water volume of the cup 11 is measured, or in case the flow in the line is constant, the water volume entering the cup 11 of the washing machine 1 may be determined from the time signal.
In one embodiment, the cleaning machine 1 is provided with a water outlet 13 and a water cup 11, a second temperature sensor 52 for detecting the temperature of water in the water cup 11, the water outlet 13 is communicated with the water cup 11, and when the temperature detected by the second temperature sensor 52 is lower than the set cleaning temperature, the water supplied by the water heater 2 is discharged through the water outlet 13.
Generally, the cleaning machine 1 is provided with a cup 11, and the cup 11 is used for receiving cleaning water. Further, the washing machine 1 is provided with a drain opening 13 and a drain pump 14. The water outlet 13 communicates with the water cup 11. The drain pump 14 is activated to drain the washing water for washing the water cup 11. The washing machine 1 may be further provided with a second temperature sensor 52 for detecting the temperature of the water in the water cup 11. When the temperature detected by the second temperature sensor 52 is lower than the set washing temperature, the drain pump 14 may be activated, and the water supplied from the water heating device 2 is discharged through the drain port 13. When the temperature detected by the second temperature sensor 52 reaches the set cleaning temperature, the cleaning pump 12 is started again to formally enter the cleaning operation, so that the cleaning water temperature is ensured to reach the set cleaning temperature.
After formally entering the cleaning operation, the drain pump 14 may be turned off. If the temperature detected by the second temperature sensor 52 is lower than the set washing temperature during the main washing, the washing water temperature may be raised by activating the heating unit, and the drain pump 14 may be maintained in a closed state. In the above-mentioned flow of detecting that the water temperature in the water cup has not reached the set cleaning temperature and draining by the drain pump 14 is mainly in the water supply stage before the main cleaning, if the cleaning operation is performed, the cleaning water temperature can be raised by the heating unit to control the drain pump 14 to be in the off state so as to ensure that the cleaning operation is not interrupted accidentally.
In a specific scenario, when the set washing temperature is higher than the target water temperature in the first circulation water path; alternatively, the water provided in the first circulation water path loses heat during the process of supplying the water to the water cup 11 of the cleaning machine 1, and when the water temperature is reduced, the water with the temperature lower than the set cleaning temperature can be discharged through the water outlet 13, so as to ensure that the water temperature for cleaning can reach the set cleaning temperature.
When the water heater 2 is a water storage type water heater, the highest water temperature which can be provided by the water storage type water heater to the cleaning machine 1 is possibly lower than the set cleaning temperature required by the cleaning machine, at this time, the water of the water storage type water heater can be utilized to firstly discharge the cold water section in the pipeline between the water heater 2 and the cleaning machine 1, and then the cleaning machine 1 is supplied with hot water with stable water temperature. After the cup of the cleaning machine 1 receives the hot water with the stable water temperature, the water temperature can be further increased by the heating unit so as to reach the set cleaning temperature.

When the water heating device 2 is provided with the soft water module 6, i.e., the water heating device 2 itself is integrated with the soft water module 6, it is possible to provide the user with soft water of a target temperature. When soft water satisfying the temperature requirement is supplied to the washer 1, the washing effect of the washer 1 can be further improved.

By reducing the concentration of calcium and magnesium ions, the scale attached to the surfaces of tableware and the washing cavity of the washing machine can be avoided, so that the washing effect is further improved.
In addition, in the case of the soft water module 6 being provided in the combined supply line, the cleaning effect achieved is similar to that in the case of the above-described integrated arrangement in the washing machine 1 or the water heating device 2, and the application will not be described here again.

Because the hot water provided by the hot water device 2 is utilized to discharge the cold water section in the joint supply pipeline 3 between the hot water device 2 and the cleaning machine 1, the water temperature supplied to the cleaning machine 1 by the subsequent hot water device 2 is higher, the water temperature supplied to the cleaning machine 1 can be effectively increased, and therefore the cleaning machine 1 can be ensured to have a better cleaning effect in a shorter cleaning time.
