TECHNICAL FIELD

[0001] The utility model relates to ice bath machine technical field especially applicable to filter core backflushing device of ice bath machine. BACKGROUND

[0002] Generally, in order to prevent foreign matter from entering into the water circulation pipeline, which may cause each related device failure, such as water pump impeller damage, mechanical seal failure, flowmeter impeller failure, valve switch abnormality, etc., it is necessary to increase the corresponding filter device in the pipeline in order to protect the above-mentioned devices. According to different application conditions, different types of filters can be adapted, and the industry generally uses mechanical filters that can be repeatedly flushed. For different user groups, related products can select different configurations of filters for different target customers, such as manual cleaning mode, automatic cleaning mode, etc. The former is generally applicable to low-configuration products, and the latter is generally applicable to high-configuration products.

[0003] In actual application, ice bath machine products will inevitably produce various impurities (such as skin flakes, hair and other foreign matter, etc.) in the bathtub after running for a certain period of time due to a large number of users, so filters must be provided in the water circulation pipeline.

[0004] However, the filter core backflushing device needs to be frequently cleaned during use, and each time the device must be stopped, the filter core must be removed, the filter core must be manually flushed, and then the device must be reinstalled and restarted, which occupies a lot of time and manpower during this period. UTILITY MODEL CONTENTS

[0005] The utility model aims at solving the problem of frequent cleaning of mechanical filter cores in the background art and provides a filter core backflushing device applicable to ice bath machines.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0007] A filter core backflushing device applicable to ice bath machines, comprising a backflushing filter body, a water inlet and a water outlet are respectively arranged at two ends of the backflushing filter body, a mechanical filter core is inserted at one end of the backflushing filter body close to the water inlet, a blowdown port corresponding to the mechanical filter core is arranged at the bottom of the backflushing filter body, a water flow reversing valve corresponding to the mechanical filter core is threadedly connected to the backflushing filter body, a flowmeter is threadedly connected to the water inlet, and a blowdown valve is threadedly connected to the blowdown port.

[0008] Preferably, the mechanical filter core is an inner filter type filter core.

[0009] Preferably, a connecting flange is fixedly sleeved at each of the water inlet, the water outlet and the blowdown port.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] The utility model discloses a mechanical filter is adjusted in structure, and water flow reversing valve is added in the inside, and the dirt outlet (electric valve or dirt valve, same below) is added outside, and the corresponding mechanical filter core can change from the manual flushing mode to the automatic flushing mode (namely backflushing device), and after the process optimization, the subsequent ice bath machine can realize the online automatic cleaning mechanical filter core. BRIEF DESCRIPTION OF DRAWINGS

[0012] Figure 1 The utility model discloses a structure diagram of filter core backflushing device suitable for ice bath machine.

[0013] In the drawing: 1 backflushing filter, 2 mechanical filter core, 3 water flow reversing valve, 4 flowmeter, 5 dirt valve. DETAILED DESCRIPTION

[0014] The technical scheme in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0015] Referring to Figure 1 A filter core backflushing device suitable for ice bath machine, including backflushing filter body 1, backflushing filter body 1's both ends are equipped with water inlet and water outlet respectively, backflushing filter body 1 is inserted with mechanical filter core 2 in the end close to water inlet, and mechanical filter core 2 is inside filter type filter core, namely water flow filters from inner wall to outer wall, and impurities stay in the filter core inside;

[0016] In the embodiment, the bottom of the backflushing filter body 1 is provided with a dirt outlet corresponding to the mechanical filter core 2, and the impurities in the filter core are directly discharged from the dirt outlet, and the water flow reversing valve 3 corresponding to the mechanical filter core 2 is screw-connected on the backflushing filter body 1.

[0017] In the embodiment, the flowmeter 4 is screw-connected at the water inlet, and the dirt valve 5 is screw-connected at the dirt outlet, and the connecting flanges are fixedly sleeved at the water inlet, the water outlet and the dirt outlet.

[0018] In the embodiment, the backwash filter 1 does not need to additionally increase the flow monitoring because the ice bath machine system is provided with the flow meter 4; when the mechanical filter core needs to use the backwash function (at this time, the flow is assumed to be set as 70% of the rated flow, the user operation interface also reminds that the flow is low, please start the backwash function in time, provides the manual key cleaning and the automatic control mode to backwash the mechanical filter core 2), because the use condition of the ice bath machine is relatively special, the short-time flow can be low, so the blow-off port can be designed to be very large, when the backwash function is started, the water flow is filtered from the outside, and the impurities in the filter core are directly discharged from the blow-off port, the efficiency is very high, so that the cost, size and other simplification requirements are met, and the troubles of stopping the equipment and manually cleaning the filter core are avoided.

[0019] In the embodiment, the original mechanical filter is adjusted in structure, and the water flow reversing valve 3 is additionally increased inside, and the blow-off port (the electric valve or the blow-off valve, the same below) is additionally increased outside, so that the corresponding mechanical filter core 2 can be changed from the manual flushing mode to the automatic flushing mode (that is, the backwash device), after the process optimization, the subsequent ice bath machine can realize the online automatic cleaning of the mechanical filter core.

[0020] The above only describes the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the application concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
