Wherein the second mode may be referred to as a heating mode.
According to the dish washer 100 disclosed by the embodiment of the invention, the water diversion valve 4 is arranged, so that the washing water can be switched in different washing modes, and in the non-heating mode, the washing water does not flow through the heating device 3, so that the water flow resistance in a water flow system in a non-heating period can be reduced to a certain extent, the water flow speed is improved, the washing speed and the cleaning degree are increased, the washing performance of the system is improved, in addition, in the non-heating mode, the opening and closing of the heating device 3 and the flow path of the washing water can be respectively and independently controlled, and the dish washer 100 is more convenient to use. In addition, the water diversion function is concentrated in one water diversion valve 4, so that the water diversion structure is compact, the loop pipeline is shortened to some extent, and the control method is simple.
In some embodiments of the invention, the heating device 3 comprises a compressor 31, a condenser 32, a throttle device 33 and an evaporator 34, which are connected end to end in order to constitute a refrigerant cycle. That is, according to some embodiments of the present invention, the dishwasher 100 is a heat pump heating type dishwasher, and the refrigerant undergoes the processes of compression, condensation heat release, throttling expansion, evaporation heat absorption in the heat pump system, and converts low-grade energy into high-grade heat energy, and then releases the high-grade heat energy into the washing water, so as to achieve the purposes of high-efficiency and low-energy consumption heating. Compared with the traditional electric heating, the coefficient of performance of the heat pump heating system is 3-4 times or even higher than that of the common electric heating technology. The dishwasher 100 adopting the heat pump heating technology has remarkable energy-saving effect, can greatly reduce the use energy consumption of the dishwasher 100, and is an effective means for reducing the use energy consumption of the dishwasher 100.
Further, a first liquid flow passage and a second liquid flow passage are defined in the condenser 32, wherein a heating water inlet 321 and a heating water outlet 322 are respectively arranged at two ends of the first liquid flow passage, and two ends of the second liquid flow passage are respectively communicated with the compressor 31 and the throttling device 33. In other words, the condenser 32 is a liquid-liquid heat exchanger, so that the heating efficiency of the condensed water can be improved.
In addition, in order to improve the heat exchange efficiency of the washing water and the refrigerant, the first liquid flow passage and the second liquid flow passage may be designed to be complex, so that the flow resistance of the first liquid flow passage may be increased, and thus the condenser 32 is directly connected to the original washing system flow passage, so that the problems of the drop of the spray arm spray pressure of the dishwasher 100, the increase of the power consumption of the washing pump 5, and the like may be caused, especially in a non-heating period. For this reason, by using the dishwasher 100 according to an embodiment of the present invention, it is possible to solve the problem of large flow resistance caused by the washing water flowing through the condenser 32 during the non-heating period by providing the water diversion valve 4.
In the heating mode, the heat pump system is turned on, so that the washing water flowing out of the washing tub 1 can be heated by the condenser, and the high-temperature washing water enters the shower arm to perform high-temperature washing on the dishes in the washing tub 1, thereby improving the washing effect.
In the non-heating mode, the heat pump system can be turned off, so that energy sources can be saved; of course, the heat pump system may be turned on as needed, and further, other devices and spaces may be heated or cooled by the heat pump system, for example, the heat pump system may be turned on, the interior space of the washing liner 1 may be heated and dried by the condenser 32, or the interior space of the washing liner 1 may be cooled and dehumidified by the evaporator 34.
Of course, the present invention is not limited thereto, and the heating device 3 according to the embodiment of the present invention may be electrically heated, for example, heating of circulating water may be achieved by heating with heating wires or thick film heating technology. The electric heating is utilized to heat the washing water, the structure is simple, and the control is simple.
The heating device 3 will be described in detail below as an example of a heat pump system.
In some embodiments of the present invention, the spray arms may include a plurality of second interfaces, and the spray inlet on each spray arm is connected to the second interface, so that the washing water can be dispersed into the spray arms for spraying after flowing out from the second interface, and the cleaning effect is better.
In other embodiments of the present invention, the spray arm may include a plurality of second interfaces, each second interface communicating with a spray inlet on at least one spray arm. Therefore, the plurality of second interfaces and the plurality of spray arms are combined in a plurality of ways, different needed connecting structures can be met, and further alternate cleaning of the spray arms is realized.
Specifically, the spray arms include a plurality of second interfaces, each second interface being connected to at least one spray inlet of one spray arm, and in the first mode, the first interface 41 is selectively in communication with at least one second interface, such that in the non-heating mode, wash water may flow into one or more spray arms as desired, thereby completing the alternating wash mode.
Similarly, the spray arms include a plurality of second interfaces, each second interface being coupled to at least one spray inlet of one spray arm, and in the second mode, the fourth interface 44 is selectively coupled to at least one second interface such that in the heating mode, wash water may flow into one or more spray arms as desired, thereby completing the alternate cleaning mode.
Here, the number of shower arms and the number of second interfaces may be equal or unequal, so that the connection of the shower arms and the second interfaces may be combined as needed. Therefore, under different modes, the washing water can enter the corresponding spray arm through the second interface to spray and clean, the cleaning modes are diversified, and the dishwasher 100 is more convenient to use. The connection of the spray arm to the second interface and the control of the tap-off valve in the corresponding connection of the spray arm to the second interface will be described below with reference to fig. 1 to 6.
Specifically, a dishwasher 100 according to one embodiment of the present invention is described below with reference to fig. 1 to 6:
the spray arm includes: the lower spray arm 23, the upper spray arm 21 and the middle spray arm 22, wherein the lower spray arm 23 is arranged at the lower part of the inner side of the washing liner 1, the upper spray arm 21 is arranged at the upper part of the inner side of the washing liner 1, and the middle spray arm 22 is arranged at the middle part of the inner side of the washing liner 1. By arranging the spray arms at the upper part, the middle part and the lower part in the washing liner 1, the upper part, the middle part or the lower part of the washing liner 1 can be communicated. In this way, in the cleaning process, the lower spray arm 23 can spray water independently, the upper spray arm 21 and the middle spray arm 22 can spray water simultaneously, or the upper spray arm 21, the middle spray arm 22 and the lower spray arm 23 can spray water simultaneously, so that the effect of alternate spraying is realized.
The second interfaces comprise two, and each second interface is connected with at least one spray arm. For example, one of the second interfaces is connected to the lower spray arm 23, and the other second interface is connected to both the upper spray arm 21 and the middle spray arm 22.
Further, in the first mode, the first interface 41 is communicated with one of the second interfaces, or the first interface 41 is communicated with the other of the second interfaces, or the first interface 41 is communicated with both the second interfaces; thus, in the first mode, when the first interface 41 is communicated with one of the second interfaces, the washing water can enter the corresponding spray arm through the second interface, when the first interface 41 is communicated with the other of the second interfaces, the washing water can enter the other corresponding spray arm through the other second interface, and when the first interface 41 is simultaneously communicated with the two second interfaces, the washing water can enter all spray arms. Thus, by communicating the first interface 41 with a different second interface, alternate cleaning in non-heating mode is achieved, depending on the needs.
That is, in the non-heating mode, the washing water does not flow through the heating device 3 (condenser 32), the alternate washing sequence is solved in the diverter valve 4, and three non-heating modes are realized: the upper spray arm 21 and the middle spray arm 22 operate, the lower spray arm 23 operates, and the upper spray arm 21, the middle spray arm 22, and the lower spray arm 23 operate simultaneously. Therefore, in the non-heating mode, the circulation washing process does not cause a loss of flow resistance due to the flow through the heating device 3 (condenser 32), affecting the shower arm pressure and washing effect.
In the second mode, the fourth interface 44 is in communication with one of the second interfaces, or the first interface 41 is in communication with the other of the second interfaces, or the first interface 41 is in communication with both of the second interfaces; thus, in the second mode, when the fourth interface 44 is in communication with one of the second interfaces, the high-temperature washing water may be introduced into the corresponding spray arm through the second interface, when the fourth interface 44 is in communication with the other of the second interfaces, the high-temperature washing water may be introduced into the other corresponding spray arm through the other of the second interfaces, and when the fourth interface 44 is in communication with both of the second interfaces, the high-temperature washing water may be introduced into all of the spray arms. Thus, alternate cleaning in the heating mode is achieved by communicating the fourth interface 44 with a different second interface, as desired.
That is, in the heating mode, the washing water flows through the heating device 3 (condenser 32), the flow path is switched in the water diversion valve 4, the washing circulating water flows back to the water diversion valve 4 after being heated by the heating device 3 (condenser 32), and three heating modes are realized: the upper spray arm 21 and the middle spray arm 22 operate, the lower spray arm 23 operates, and the upper spray arm 21, the middle spray arm 22, and the lower spray arm 23 operate simultaneously. Thus, alternate washing over the full time course of the heating process can be achieved.
